Published: July 2024

This study aims to understand the characteristics of the dental visit, and to evaluate the compliance with regular check-up of infants who visited Wonkwang University Daejeon Dental Hospital(WKUDH) from January 2008 to December 2017. A retrospective analysis of clinical data including chief complaint, visit route, performed treatment option and pattern of recall visit for 3 years after the first visit was conducted based on the electronic medical record. The compliance with a regular check-up of each individual was evaluated according to the intervals and the number of recall visits. Within 321 infants, 19.3% of the participants were under 6 months old whereas 80.7% were between 6 months and 1 year old. While the presence of natal/neonatal teeth was the most frequent chief complaint of infants under 6 months old was, dental trauma was the most common one of the infants between 6 months and 1 year old. The participants were classified into 4 groups according to the compliance with regular check-up for 3 years. The group which showed poorer compliance with regular check-up occupied bigger proportion. It is necessary to understand why and how infants make their first visit to dental clinic, which would be a groundwork to provide adequate clinical management and oral health education for the infants as well as their caregivers.

Published: July 2024

Synovial chondromatosis is an uncommon benign lesion in which the synovial membrane within the joint forms cartilaginous nodules and loose bodies due to cartilaginous metaplasia. It is rare to develop in the temporomandibular joint, and may be accompanied by cranial base expansion or temporal bone morbidity. A 41-year-old male patient visited our hospital complaining of preauricular pain and crepitus. On CT and MRI, increased synovial fluid in the joint cavity, loose body, temporal bone erosion and cranial base expansion were observed. It was diagnosed as synovial chondromatosis through imaging and clinical symptoms. After arthrocentesis, the symptoms slightly decreased, and arthrotomy was performed for complete resolution of the pain. The patient's pain and crepitus were resolved, and no recurrence of the lesion was observed.

Authors: Kim Young-Hyun , Park In-sook , Kim Ji-Rak
Published: July 2024

Pyogenic granuloma is a prevalent, benign muco-cutaneous lesion with exuberant tissue caused by local irritation or trauma. The term ‘pyogenic granuloma’ can be a misnomer because the lesion neither causes pus formation nor represents a true granuloma, histologically. Pyogenic granuloma appears as a sessile or peduncu-lated exophytic mass covered by yellow fibrinous membrane. Its smooth or lobulated surface may easily bleedor ulcerated. Gingiva is the most common site (75% of all cases), and lips, tongue, buccal mucosa and the hardpalate are also affected. Surgical excision is the first choice of treatment many other treatment modalities can beused. After surgical excision, recurrence occurs up to 16% of these lesions. It is believed that recurrence ensues as a result of incomplete excison, failure to eliminate etiologic factors or repeated trauma.This case report describes the use of diode laser in surgical excision of the recurred pyogenic granuloma on the hard palate

Authors: Lee Songhyun , Jeon Jung Hee , Lee Kee-Joon
Published: July 2024

Currently the unofficial health care system is growing in North Korea as the socialist public free medical treatment system is not working properly due to the prolonged economic recession.In the Kim Jong-Un era, the North Korean government has been making investments in the medical sector recommending policies for the devel-opment of the health care system. Suggestions such as the establishment of a health care system and large scale hospitals have been discussed, but the public and private systems are unbalanced in all the medical segments where the private sector seems to be growing at a faster pace. Such examples would be the pharmaceutical supply and medical delivery systems.A survey of in-depth interviews with 53 North Korean defectors who resided at Hanawon, South Korea in 2020 revealed that dentistry, particularly the prosthetic sector, is recognized mostly as private paying care and is rapidly growing. Overall oral healthcare, including dental care, is provided in private facilities of dental care providers outside the current public healthcare system. The growth and demand for dental care is supported in that it is observed very few patients who had missing teeth had received prosthetic treatment before 2010, while nearly half of those with lost teeth received prosthetic treatments at a personal private cost after 2018.Through this research, it is evaluated there is a strong growing demand for dental care in North Korea, and unofficial private dental care is filling the need as the current government system is inadequate.

Published: July 2024

Purpose: This study was conducted to evaluate the influence of contamination of the scan-mirror on the accuracy of obtained scan data by using two type of intra-oral scanner.Materials & methods: After printing the Crown & inlay specimens according to the ISO standard, the data values of the specimens were calculated using a model scanner and two intra-oral scanners. Experimental groups were classified into three groups according to cleanliness of scan-mirror.Each group performed 10 repeated scans. Data analysis was performed with statistical software (SPSS 25, IBM Corp., Armonk, New York, USA) to check the normality of data sets and ANOVA & Bonferroni test was performed for multiple comparisons between groups.Results: The d1(top diameter of cylinder), d2(bottom diameter of cylinder), h(cylinder height) values of the crown specimens and d1(top diameter of cavity), d2(bottom diameter of cavity), h(cavity height) of the inlay specimens compared with the reference data using two intra-oral scanners were similar for each group.Discussion: In the scanning process, it was observed on the screen that a data value that deviated from the normal range was inputted in the group with higher level of contamination, but they were removed through the software’s own filtering and post-processing, and it was found that there was no significant effect on the result values.Conclusion: Under the conditions of this study, as the degree of contamination of the scan-mirror surface increased, an inaccurate capture screen appeared, but it did not significantly affect the accuracy and precision of the scan data.
The endodontic treatment for immature permanent teeth with pulp necrosis
Authors: Lee Chaehwan
Published: July 2024

Root canal treatment of immature permanent teeth with pulp necrosis presents clinical difficulties due to wideroot canals and apical foramen. In addition, there is a high risk associated with a potential cervical fracture due to the thin dentinal walls even after successful root canal treatment. Thus, a notion of continued root development of the immature tooth has continuously explored. Regenerative endodontic treatment (RET) provides a biological treatment approach based on regeneration and revascularization principles. Unlike conventionalapexification, RET promotes the growth and development of immature roots and the healing of the periapical lesion via disinfection of the infected root canal system. Therefore, RET may provide a positive effect on thelong-term prognosis of immature permanent teeth with pulp necrosis.

Authors: Kim Bumsu , Kim Heechul
Published: July 2024

With the development of oral scanners and dental CAD/CAM systems, a various prostheses can be manufactured more accurately than before. If equipment such as a dental milling machine and 3D printer are equipped in the hospital, the dentist can produce the desired prosthesis relatively quickly and easily. Digital prosthesis production in the hospital can reduce chair time and the time for model making and delivery compared to the impression taking method. If the dentist actively participates in the prosthesis manufacturing process, it can improve understanding and help the clinical process. If conditions such as CAD software or equipment installation do not allow, communication between the dentist and the laboratory can be improved through the Viewer provided by the company. It should be remembered that the importance of basic treatment procedures such as tooth preparation, accurate margin, and soft tissue management remains the same even when digital prostheses are manufactured.
Maxillary expansion for treatment of obstructive sleep apnea
Authors: Lee Kee-Joon , Choi Yoon Jeong
Published: July 2024

Patients having obstructive sleep apnea frequently present malocclusion such as maxillary constriction, posterior crossbite, and long face. Maxillary expansion has been addressed to correct the malocclusion and to improve obstructive sleep apnea. In growing patients, rapid palatal expander (RPE) can separate the midpalatal suture and expand the maxilla, which results in increase of volume in the nasal cavity and nasopharynx as well as increase of the cross-sectional area. In non-growing patients, miniscrew-assisted rapid palatal expander canbe used for the same effect. Maxillary expansion can be used for correction of obstructive sleep apnea in caseof maxillary constriction.

Cemento-osseous dysplasia in need of careful examination : a case report
Authors: Cho Juyeon
Published: July 2024

Cemento-osseous dysplasia (COD) is a fibro-osseous lesion of the maxilla and mandible, originating from a periodontal ligament. It resembles a periapical lesion such as a periapical abscess or a cyst in its early stage. Usually, the affected tooth is vital and without symptoms. A healthy 35-year-old female was referred to the endodontic department for evaluation and endodontic treatment of an amalgam restored mandibular first molar with an apical radiolucency. Since the tooth was sensitive to a cold stimulus, chronic apical periodontitis was suspicious at first sight. But after clinical and radiographic evaluations, multiple periapical COD involving vital teeth of the mandible was diagnosed. No specific treatment of COD was scheduled except for renewing the pre-existing restoration. The present case is a confusing case since COD was associated with an asymptomatic tooth. Knowledge of the clinical features related to pulp vitality tests and cone-beam computed tomography (CBCT) helps determine the differential diagnosis between COD and a periapical lesion.

Published: July 2024

This study aimed to investigate occupational risk among dental practitioners and its associated factors. Ma-terials and Methods. A total of 505 dentists and other dental staff from Korean dental institutions were includedin this study. A self-report questionnaire on demographic characteristics, perception and experience of occupa-tional hazards, the prevalence of chronic diseases, and type of musculoskeletal problems, were distributed to the participants. A logistic regression model was used to identify factors affecting the perception of occupational hazards. Results. Among the participants, 61.58% were dentists and 38.42% were dental staff (dental hygien-ists, dental technologists, and other office workers). Overall, 48.12% had a serious perception of occupationalhazards, and 77.53% had experienced occupational hazards. The common occupational hazards encounteredwere stress (20.58%), exposure to hazardous materials (15.44%), and cross-infections (14.75%). Regardless ofparticipants’ occupation and their perception of occupational hazards, musculoskeletal problems had the high-est prevalence (35.94%) (neck/shoulder pain [35.53%], lower back pain [24.74%], and wrist pain [19.07%]).Those with experience of occupational hazards and musculoskeletal problems were more likely to recognize occupational hazards (odds ratio 5.186 and 1.535, respectively; p<0.05). Conclusion. Approximately half of the dental workers were aware of the risk of occupational hazards. This study highlighted that the more the partici-pants experience occupational hazards, the more likely they are to recognize occupational hazards. The high prevalence of physical and mental occupational hazards indicates the need for preventive measures to reduce occupational risk in dental practices.
Review of several clinical factors that affect the occlusal bite forces
Authors: Park Jaehan
Published: July 2024

Occlusal bite forces are the most critical consideration factor in treatment planning. Measurement methods ofocclusal bite forces were developed in a century, and affected factors are studied in many experiments. Gender, age, shapes of facial morphology, teeth position, periodontal states, etc., are revealed affective aspects of theocclusal bite forces. The dental clinician should make a treatment plan by considering occlusal bite forces and would predict the patient's prognosis. In clinical procedures, several specific factors that include endodontic treatment, implant treatment, and com-plete denture prosthesis cause severe results after treatments. If clinicians do not consider these factors before the treatment procedures, extraction of the tooth, implant, and dismission of the complete denture are struggled by patients. These factors (endodontic treatment, Implant, complete denture prosthesis) cause the changes of occlusal bite forces, and then consideration of these changes makes a great result of treatment. The purpose of this study was to summarize the parts that clinicians can refer to based on reviewing studies on complex factors that affect occlusal bite force.
Strategy to obtain an accurate occlusal registration using intraoral scanners
Authors: Lee Hyeonjong
Published: July 2024

Obtaining precise occlusal registration is one of the main issues in prosthodontics. The adequate trimming strategy of bite material and removing the bubbles in the cast are important and time-consuming procedures to acquire the correct occlusal registration in the conventional pathway. In the era of digital dentistry, the use of intraoral scanners has been widely spread out, and the occlusal registration step is automatically performed through the software algorithm. However, the accuracy of occlusal registration using intraoral scanners is differ-ent depending on the digital trimming strategy. Clinicians are required to understand the theoretical knowledge for occlusal registration and data trimming strategy.

Authors: Jeong Sung-Hee
Published: July 2024

Chronic toothache with no specific cause, no standardized characteristics, have been called ‘Atypical Odontalgia(AO)’. Recently, it has been replaced by the term 'persistent dentoalveolar pain disorder (PDAP)'.Since patients have various causative factors and their symptoms are diverse, it is also a challenge for clini-cians to make an accurate diagnosis. PDAP is a persistent pain, and various aspects appear. There are no special triggers, exacerbation or alleviation factors, no response to anesthesia tests and dental treatment. The purpose of this study is to assist clinicians in diagnosing patients with unexplained tooth pain by examining the clinical characteristics, differential factors, and treatment of PDAP.
An Update on Diagnosis and Treatment of Bruxism
Authors: Lee Yeon-Hee
Published: July 2024

Bruxism is a movement disorder characterized by grinding and clenching of teeth. Polysomnography and controlled sleep studies have allowed us to better understand the relationship between sleep stages, microarousal responses, and autonomic function and bruxism. Bruxism can sometimes threaten the integrity of the masticatory system when the magnitude and direction of the applied force exceeds the system's adaptive capacity. Thus, bruxism is the most common contributing factor found in patients with temporomandibular disorder and orofacial pain. In addition, it contributes to abnormal wear of teeth, periodontal disease, and causes considerable problems in dental care. There are two main types of bruxism, which are associated with various circadian cycles (sleep and wake bruxism) that may differ in pathophysiology. Bruxism is considered to have multifactorial etiology. Sleep bruxism have been associated with peripheral factors, psychosocial influences such as psychological distress or anxiety, and central pathophysiology involving brain neurotransmitters. Currently, there is no specific and effective treatment that can permanently get rid of the bruxism. Palliative treat-ment and alternatives have been mainly proposed to prevent the pathological effects of bruxism on the oral and maxillofacial system and to ameliorate adverse clinical outcomes. This study is a review of literature published in the last 30 years on 'bruxism', especially sleep bruxism, and is performed using Medical Subject Headings (MeSH) Database and PubMed search engines.

Published: July 2024

The meta-evaluation of dental education evaluation and accreditation was conceptualized as 'evaluating the evaluation and accreditation system' in order to improve the quality of evaluation. In order to perform meta-evaluation of dental education evaluation and accreditation, which seeks improvement directions by comprehensively and systematically evaluating and analyzing dental education evaluation and accreditation, the development of evaluation criteria should be preceded. The purpose of this study is to redefine the direction of dental education evaluation and accreditation and to establish improve-ment plans by developing criteria for meta-evaluation and confirming its validity. In this study, the meta-evaluation criteria and sub-evaluation system for evaluation and accreditation by Korean Institute of Dental Education Evaluation (KIDEE) were developed. In order to confirm the validity and reliability of the meta-evalu-ation criteria and sub-evaluation system, a questionnaire was conducted targeting the self-evaluation members of the evaluation target institutions with a high understanding of evaluation and the evaluation and accreditation members of KIDEE.The developed meta-evaluation criteria and subsystem for evaluation and accreditation should be used for the purpose of introducing a quality improvement system for evaluation and accreditation. It is expected that the meta-evaluation of KIDEE will be conducted regularly as a meta-evaluation criteria and sub-system faithfully to this purpose.

Oral health care in the long COVID era : Focusing on the relationship between COVID-19 and periodontal disease
Authors: Jeong Jae Seok , Heo Seok-Mo
Published: July 2024

The purpose of this study is to investigate the relationship between periodontal disease and coronavirus disease 2019 (COVID-19) as a respiratory disease, and to suggest its molecular biological mechanism. Oral bacteria and viruses can be aspirated into the respiratory tract and may cause respiratory diseases. The COVID-19 virus can inhabit, replicate and spread in the oral environment including dental plaque, saliva, and periodontal pockets. The COVID-19 virus can induce strong innate immunity and inflammatory responses by binding to the angiotensin-converting enzyme 2 receptors, which are abundantly present in the oral stratified epithelium in the oral cavity. The COVID-19 virus may activate inflammasome, one of inflammatory key factors in cell cytoplasm. In patients with periodontal disease, oral hygiene habits, professional oral cleaning, and plaque control management are effective for reducing the possibility of COVID-19 infection. This review is based on the evidences from COVID-19 related literature in the last two years.

Root coverage achieved with a connective tissue graft overlaid onto allogeneic demineralized dentin matrix incorporated with rhBMP-2
Authors: Kwak Han-wool , Um In-Woong , Ku Jeong-Kui
Published: July 2024

Autogenous demineralized dentin matrix (DDM) has been widely used in implant dentistry and highlighted as a potential carrier of recombinant human bone morphogenetic protein-2 (rhBMP-2). Allogeneic DDM (Allo-DDM) is comparable to autogenous DDM in safety and effectiveness. The various endogenous growth factors in dentin, including BMP, transform-ing growth factor, fibroblast growth factor, and insulin growth factor suggest that DDM incorporated with rhBMP-2 (DDM/ rhBMP-2) may exert a synergistic effect that promotes soft tissue healing through angiogenic activity, in addition to its osteoinductivity. This case report describes a successful outcome of root coverage where connective tissue graft (CTG) was overlaid onto Allo-DDM incorporated with rhBMP-2 (Allo-DDM/rhBMP-2).

Published: July 2024

Duration of administration of related medications, presence of bacterial infections in necrotic areas, and methods of treatment have been suggested as factors related to the recurrence of MRONJ. The purpose of this study was to investigate recurrence risk factors in patients who had undergone surgical treatment. The recurrence rate was statistically significant when the teeth affected by alveolar bone necrosis were removed together. When comparing patients who received post-operative antibiotic treatment, recurrence was significantly reduced. Comprehensive surgical approaches, including the extraction of adjacent teeth during surgery, and appropriate post-operative antibiotic therapy can be effective strategies for reducing the recurrence rate of MRONJ.

Authors: Noh Kwantae
Published: July 2024

For the long-term success of implants, not only the implant surgery but also the design of the prosthesis is important. The subgingival part of an implant prosthesis should be designed to avoid bone interference, maintain the volume of surrounding soft tissue, and be easy to clean. The supragingival part of the prosthesis must be manufactured so that food does not accumulate, is easy to clean, and forms appropriate occlusion. In this paper, I will describe the appropriate form of implant prosthesis for a successful long-term prognosis.

Authors: Kwon Jung-Wook , Hyun Seung-Chul , Kim Dong-Hyuck , Lee Eui-Seok , Lim Ho-Kyung
Published: July 2024

This paper reviewed prolotherapy as an approach to treating temporomandibular joint disorders (TMD), focusing on temporomandibular joint subluxation and hypermobility. Prolotherapy, commonly used in orthopedics, involves injecting substances like dextrose or lidocaine to promote healing in musculoskeletal conditions. Clinical studies in which this prolotherapy was used for TMD were reviewed. Total 13 papers involving 372 patients (Male 90, Female 282) were examined, considering factors such as dextrose concentration (10%~50%), injection frequency (one to four times), injection period (one to four weeks) and injection sites. The assessment primarily focused on pain reduction and changes in maximum mouth opening after prolotherapy. In all papers, a consistent trend of pain reduction after prolotherapy was observed. Regarding maximum mouth opening, there were 6 cases of decreased range and 7 cases of increased range. With prolotherapy's rec-ognition as a new medical technology for TMD, it emerges as a potential alternative treatment, highlighting its significance in the field.

Authors: Hyun Seung-Chul , Kwon Jung-Wook , Kim Dong-Hyuck , Lee Eui-Seok , Lim Ho-Kyung
Published: July 2024

Temporomandibular disorders (TMD) are challenging to treat despite various existing methods. Stress on the temporomandibular joint (TMJ) leads to an accumulation of reactive oxygen species, promoting inflammation and cartilage degra-dation. Resveratrol, a natural polyphenol, inhibits inflammatory pathways and suppresses chondrocyte apoptosis, making it a promising candidate for TMD treatment. This review analyzes six studies with 3 kinds of animals on the intra-articular application of resveratrol for treating arthritis. This paper aims to elucidate the potential of resveratrol administrations into the articular cartilage to improve severity of arthritis, providing a foundation for future research and clinical investigations.

Authors: Cho Sung Hun , Park Hyun-Jun , Kim Hee-Jung , Song Joo-Hun
Published: July 2024

In clinical practice, patients often exhibit extensive dental wear and fractures due to deleterious habits such as bruxism, clenching, and suboptimal oral hygiene. These cases may necessitate comprehensive full-mouth restorations that typically involve numerous dental visits, which can potentially lead to patient fatigue, delayed recovery, and uncertain treatment outcomes. The present study reports an innovative approach in which provisional restorations are digitally designed and fabricated on the same day as tooth preparation. The morphology of the provisional restorations that the patient adapted to is then replicated onto the final restorations with dual-scanning technique. The study aims to simplify treatment progress and achieve higher predictability of the final restorations, highlighting the advantages of dual-scanning techniques in simplifying and expediting the treatment process.

Authors: Kwak Hyun-Jin , Kim So-Hyeon , Nam Yoon-ju , Kim Chul-Hoon , Kim Jung-Han , Kim Bok-Joo
Published: July 2024

Oral vestibule is important in oral health. Various vestibuloplasty techniques are used in cases involving vestibule loss. This case report describes the treatment outcomes from performing modified Kazanjian vestibuloplasty with artificial der-mis graft and connective tissue graft for severe trismus and mandibular denudation caused by shallow vestibule and postoperative scarring after facial contouring surgery. Based on an accurate understanding of the anatomical structures within the oral cavity, problems caused by multiple surgery due to inflammatory complications after a facial contouring surgery, including scarring, discomfort during mouth and cheek movements due to loss of oral vestibule, trismus, alveolar bone exposure, and gingival recession, were resolved with a single surgery. When performing intraoral surgery, it is necessary to understand the meaning and importance of vestibule and perform incision and suturing to minimize the shallowing of vestibule. In cases involving vestibule loss, appropriate techniques should be selected to ensure restoration of vestibule.

Published: July 2024

Objective: The purpose of this study was to evaluate the effects of the mini-implant assisted rapid palatal expansion on the nasal septum and the inferior nasal meatus (INM) in the patients with nasal septal deviation. Methods: The CBCT images were taken before (T0), after (T1), and more than 5 months after (T2) MARPE in 17 patients who had NSD. According to the direction of the NSD, the concave side was set as group 1 and the convex side was set as group 2 by patient. The volume of the INM, nasal septal tortuosity ratio were calculated. Also, to evaluate 3-dimensional changes of the nasal septum, distance between C point (The junction of perpendicular plate of ethmoid bone and vomer) and three vertical planes were calculated. And distance between C point and lateral wall of nasal cavity was measured. Results: The total volume of the INM increased significantly after MARPE (p < 0.001). The distance from the C point to the vertical plane increased significantly after MARPE (p < 0.01). Also, there was a significant difference between the groups in the distance between the C point and the lateral wall of nasal cavity (p < 0.001) before and after treatment. But there was no significant difference in the increase ratio. Conclusion: After MARPE, the volume of INM was significantly increased. The nasal septum was more displaced to the deviated side without a significant morphological change. But the increase ratio of both group was similar.

Objectives: The aim of this study was to compare the differences in the morphology of the lips according to anteroposte-rior dentoskeletal patterns and facial divergence.Materials and Methods: The samples were composed of the frontal facial photographs of 117 adult patients who satisfied all the cephalometric measurements for six groups (Class I or II or III and normodivergent or hyperdivergent). The morphol-ogy of the lips was evaluated on the frontal facial photographs and the measurements were compared between the groups.Results: In the normodivergent groups, the height-to-width ratio of the lip vermilion was significantly greater in the Class II group than in the Class I group, and the labrale superius angle and upper lip convexity of the Class II group was smaller than that of the Class I group. In the hyperdivergent groups, the stomion inferius angle of the Class III group was smaller than that of the Class II group. Lower facial height and the interlabial gap in the hyperdivergent groups tended to be larger than those in the normodivergent groups. The height-to-width ratio of the lip vermilion and the commissure height were larger in the hyperdivergent groups than in the normodivergent groups. However, the upper lip height and philtrum height did not differ between the hyperdivergent and normodivergent groups.Conclusion: The morphological characteristics of the lip vermilions on the frontal view differed according to the sagittal dentoskeletal relationship and facial divergence.

Authors: Hwang Kyung-Gyun
Published: July 2024

Pain control according to sensory nerve innervation in the oral and maxillofacial area is an important part of clinical dentistry for treating diseases of teeth, periodontal tissue, oral mucosa, temporomandibular joint, and maxillofacial area. Local anesthesia has been used the basic pain control procedure in dental treatment. Dental local anesthesia is a basic procedure in the curriculum of dental schools, and is the most frequently used dental procedure by many dentists in clinical practice. As one of these procedures, we would like to review the considerations of whether clinical guidelines for these procedures are necessary.
Case report of peritonsillar space abscess misdiagnosed as parapharyngeal space abscess
Authors: Choi Moon Gi
Published: July 2024

Peritonsillar abscess, the most commonly occurring deep infection of the neck, involves formation of pus in the peritonsillar space. Although abscess of the peritonsillar space and abscess of the parapharyngeal space occur in different anatomical spaces, the clinical symptoms are similar, making it difficult to distinguish between the two diseases. Delay of treatment can result in transfer of infection from one space to another.Improper treatment or delayed treatment of a peritonsillar abscess can lead to serious complications such as an abscess of the parapharyngeal space, necrotizing fasciitis, internal jugular vein thrombosis, and descending mediastinitis. These condi-tions can be life-threatening due to airway obstruction or sepsis.Drainage, fluid therapy, and antibiotic therapy provide the basis for treatment of peritonsillar abscess. Airway manage-ment is the most urgent priority. Airway obstruction can occur immediately during a deep infection of the neck space and is a common cause of death rather than sepsis. Immediate airway management is required in cases where there is evidence that airway obstruction is imminent. Transoral incision and drainage is the most commonly used method for drainage of peritonsillar abscesses. However, transoral incision and drainage may not be sufficient and use of a transcervical approach may be necessary.The author reports on a case of an abscess of the peritonsillar space misdiagnosed as an abscess of the parapharyngeal space and on issues that should be considered with regard to abscess of the peritonsillar space.

Purpose: To investigate the characteristics of impacted teeth in Korean patients and the factors affecting the treatment success and period of upper impacted canines.Materials and Methods: Among the patients who visited Department of Orthodontics at Gil Hospital from 2010 to 2019, we evaluated 438 subjects who had sufficient medical records for evaluation of impacted tooth characteristics.Results: A total of 570 cases ware evaluated for this study (316 cases in male, 254 cases in female patients) and the total number of patients was 438, of which 240 were males and 198 were females. Most of them were between the ages of 11 and 15, and the number of cases in the age group reached 298. There were 406 cases in the maxilla and 164 cases in the mandible respectively. The impacted teeth were often located in the center of arch rather than buccal or lingual. Repositioned flap (RF) method was the most common surgical exposure technique. Orthodontic treatment was performed in 378 cases, and the success rate was 94.1% in the maxilla, and 93.6% in the mandible. In order to find out the factors affecting the treatment success and treatment duration of maxillary impacted canines, gender, age, axis angulation and tooth position were evalu-ated. Age was the most significant factor in determining the treatment success, while ankylosis was the most common cause of the treatment failure. And age and axis angulation were factors influencing the treatment period.Conclusion: It is necessary to make various and continuous efforts to increase the treatment success rate and shorten the treatment period of impacted teeth.

Published: July 2024

Childhood obesity is a common chronic disease in childhood, and its prevalence and socioeconomic costs have increased worldwide over the past 40 years. The World Health Organization has designated obesity as a global epidemic, emphasizing the need for its treatment and management. The impacts of childhood obesity on dentistry include a higher risk of dental caries, advanced dental development, as well as psychological changes (anxiety, depression, attention deficit hyperactiv-ity disorder) and physical changes (increased complications, changes in drug metabolism) that should be considered when implementing preventive strategies, orthodontic treatment, behavior management and sedative procedures. Dentists should regularly check child’s body mass index and diet for every child visiting dental office. Parental obesity, consumption of sugar-sweetened beverages, poor dietary habits, and lack of exercise can be a risk factors for obesity in normal/overweight child. Diet counseling should be provided to high-risk children and their parents. Preventing childhood obesity is crucial, and the key point in treating childhood obesity is behavior modification therapy, which focuses on regulating daily eatinghabits and physical activity. Dentists should recognize the seriousness of childhood obesity and participate in the prevention and management of the obesity epidemic, thus enhancing oral and systemic health
