Abstract
Changes that occurred in the pattern of tooth extraction in the last 13 years among a population of children in Nigerian were studied. The result of this study was then compared to that of a past study done in the same institution 13 years earlier. Information on age, gender, and indication of tooth extraction was collected prospectively from 379 consecutive patients who visited the outpatient Pediatric Dental Clinic for the first time during the year 2002. Results showed tooth extraction due to caries decreased, while there was an increase in tooth extraction from an apparent increase in orthodontic treatment needs. Acute necrotizing ulcerative gingivitis (ANUG), a significant cause of tooth loss in the last decade, decreased significantly. The pattern of deciduous tooth loss also changed as more anterior teeth were lost for orthodontic reasons in this present study. The pattern of tooth loss in the permanent dentition remains very similar to that of the past study, though more premolars were lost in the present study. There appears to be an increasing need for tooth extractions in orthodontic treatment for this population of children. The focus of planned dental health care provisions, treatment policies, and training emphasis in child dental care may need to shift to addressing orthodontic needs.

Anterior Esthetic Gingival Depigmentation and Crown Lengthening: Report of a Case
Authors: Nandakumar K. , Roshna T. 
Published: July 2019

Abstract
Excessive gingival display space and gingival hyperpigmentation are major concerns for a large number of patients visiting the dentist. Melanin hyperpigmentation usually does not present a medical problem, but patients usually complain of dark gums as unaesthetic. This problem is aggravated in patients with a “gummy smile” or excessive gingival display while smiling. Esthetic periodontal plastic surgery is especially rewarding in such individuals with compromised esthetics. A case is reported here on the cosmetic correction of “black gums” and “gummy smile.” Periodontal plastic surgery combining gingival depigmentation and esthetic crown lengthening was performed in a single appointment using scalpel surgical technique. The outline of steps involved in the surgical procedure is demonstrated and a brief review of the various gingival depigmentation techniques is depicted here.

Authors: Abou-Atme Youssef S. , Melis Marcello , Zawawi Khalid H. 
Published: July 2019

Abstract

Objectives
The aim of this experiment was to detect pressure pain threshold (PPT) differences on intra-oral palpation of the lateral pterygoid muscle (LPM) between subjects diagnosed with temporomandibular disorders (TMD) and controls.

Methods
Thirty-one consecutive female TMD patients and 31 age and gender matched controls underwent palpation of the LPM using an algometer made with a queue-tip connected to a digital scale, and PPT was measured.

Results
Mean PPTs of the right and left LPM of the controls were respectively 191g (49KPa) and 200g (51KPa), and mean PPTs of the right and left LPM of TMD patients were respectively 245g (62KPa) and 256g (63KPa). ANOVA between the four PPT measurements showed significant difference only between the PPT readings of the right LPM of the controls and the left LPM of the patients (p<0.05).

Conclusions
The findings of this study suggest that PPT measured by means of the described algometer is not decreased in TMD patients as compared to control subjects.

The Economics of Pit and Fissure Sealants in Preventive Dentistry: A Review
Authors: Kitchens Dinah H. 
Published: July 2019

Abstract
Oral diseases are progressive, cumulative, and become more intricate to treat with advancement. While dental caries is an infectious transmissible disease with children being at the highest risk, primary prevention can reduce this risk. Primary prevention in dentistry is usually considered to be community fluoridated water supplies, professional fluoride treatments, and pit and fissure sealants. While community fluoridated water supplies have been proven to be cost-effective, the cost-effectiveness of pit and fissure sealants has primarily been studied in school–based programs of children from low socio-economic backgrounds. Dental sealant programs are just one way to help increase primary prevention in the oral health disparities of children. The purpose of this paper is to review the literature regarding the cost-effectiveness of pit and fissure sealants as a preventive strategy in preventive dentistry.

Squamous Cell Carcinoma of the Oral Tissues: A Comprehensive Review for Oral Healthcare Providers
Authors: Bsoul Samer A. , Terezhalmy Geza T. , Huber Michaell A. 
Published: July 2019

AbstractNorth Americans in 2004 were projected to die from oral and pharyngeal cancer at a rate of 1.2 per hour. Oral healthcare providers can be instrumental in reducing the incidence of oral and pharyngeal premalignant and malignant lesions by identifying patients with high-risk behavior, educating their patients about the consequences of their high-risk behavior, and by early detection of premalignant and malignant conditions. The fact only 34% of the cancers of the oral cavity and larynx are localized at the time of diagnosis and evidence that at least one third of the patients diagnosed with an oral or pharyngeal malignancy have undergone oral cancer screening within the past three years suggests the current protocol for the early detection of pre-malignant or malignant changes appears to be deficient. To facilitate early diagnosis, oral healthcare providers must take into consideration the capriciousness of oral cancer and must be familiar with the availability and application of diagnostic modalities beyond conventional visual inspection and palpation of oral soft tissues. This article provides a comprehensive review of the disease for healthcare professionals.CitationBsoul SA, Huber MA, Terezhalmy GT.

Published: July 2019

Abstract
Experimental findings suggest a protective role for cyclic nucleotides against induction of oxidative stress in saliva. Oxidative stress is a major contributor to the pathogenesis of inflammatory diseases. This study was conducted to evaluate salivary oxidative stress along with cGMP and cAMP levels in periodontitis subjects. cAMP and cGMP are second messengers that have important roles in salivary gland functions. Unstimulated whole saliva samples were obtained from periodontitis patients and age- and sex-matched healthy individuals. Saliva samples were analyzed for thiobarbituric reactive substances (TBARS) as a marker of lipid peroxidation, ferric reducing ability (total antioxidant power, TAP), and levels of cAMP and cGMP. Concentrations of cAMP and cGMP were reduced in the saliva of patients with moderate and severe periodontitis. Saliva of patients with severe periodontitis had higher TBARS and lower TAP than control subjects. The presence of oxidative stress and lower levels of salivary cGMP and cAMP in periodontitis are in association with disease severity.

Report of Ankylosis of the Temporomandibular Joint: Treatment with a Temporalis Muscle Flap and Augmentation Genioplasty
Authors: Martins Wilson Denis 
Published: July 2019

Abstract
A case of true bilateral ankylosis of the temporomandibular joint (TMJ) is presented. A 19-year-old male patient had a life-threatening ear infection at the age of ten resulting in a progressive restriction of his mouth opening. He presented with almost complete lack of mobility of the mandible. Surgical treatment was a resection of the ankylotic mass, interpositional temporalis composite muscle flaps, and early mobilization and aggressive physiotherapy. The functional results of the interpositional arthroplasty were excellent. After a twoyear follow up, an augmentation genioplasty was performed in order to improve facial aesthetics.

Abstract

Objective
The purpose of this study was to evaluate the two year clinical performance of posterior composite restorations in endodontically treated premolars and molars using a hybrid composite (Filtek Z-250, 3M ESPE) and a total etch bonding system (Single Bond, 3M ESPE).

Method and Materials
Thirty-nine class II restorations in endodontically treated premolars (n=11) and molars (n=28) of 27 patients (14 female, 13 male, mean age 36.51) in 16 maxillar and 23 mandibular teeth were placed by one operator. Restorations were evaluated by two experienced investigators at baseline, 12 months, and 24 months according to the modified United States Public Health Service (USPHS) criteria that included retention, color match, marginal discoloration, secondary caries, anatomic form, marginal adaptation, and surface texture. All restorations were able to be evaluated at baseline, 12 months, and 24 months.

Results
Paired samples t-test showed only marginal discoloration showed a statistically significant difference (p<0.05) at the end of 24 months, and no other significant differences were observed for the other variables examined over the duration of the study. None of the restored teeth showed periapical pathology at the end of 24 months.

Conclusion
At two years, limited deterioration in marginal discoloration was detected. The clinical performance of posterior composite restorations in endodontically treated teeth using Filtek Z250 was found clinically acceptable after two years.

Temporomandibular Joint Clicking Noises Caused by a Multilocular Bone Cyst: A Case Report
Authors: Özçelik Tuncer Burak , Ersoy Ahmet Ersan 
Published: July 2019

AbstractWhen diagnosing patients with temporomandibular disorder (TMD) symptoms, the possibility of unusual causes must be considered, including neoplastic disorders, as well as infections and inflammatory disease. Therefore, radiologic examination may prove to be invaluable in the differential diagnosis of TMDs. This article describes a patient whose temporomandibular joint (TMJ) noise was initially diagnosed by another dental clinic as a TMJ anterior disc displacement with reciprocal clicking. Occlusal splint therapy was used for nearly three to four months but did not improve the TMJ noise condition. When the patient was examined clinically and imaged with magnetic resonance imaging (MRI) and computed tomography (CT), a multilocular bone cyst (MBC) was suspected. The cyst could cause surface irregularities in the posterior part of the left eminence of the temporal bone, which could be the source of the clicking noise.CitationÖzçelik TB, Ersoy AE.

Fiber-reinforced Composite Substructure: Load-bearing Capacity of an Onlay Restoration and Flexural Properties of the Material
Authors: Lassila Lippo V.J. , Vallittu Pekka K. , Garoushi Sufyan K. , Tezvergil Arzu 
Published: July 2019

Abstract

Aim
The aim of this study was to determine the static load-bearing capacity of composite resin onlay restorations made of particulate filler composite (PFC) with two different types of fiber-reinforced composite (FRC) substructures. In addition, flexural properties of the material combination and the effect of polymerization devices were tested.

Methods and Materials
Specimens were prepared to simulate an onlay restoration, which consisted of 2 to 3 mm of FRC layer as a substructure (short random and continuous bidirectional fiber orientation) and a 1 mm surface layer of PFC. Control specimens were prepared from plain PFC. In Group A the specimens were incrementally polymerized only with a hand-light curing unit for 40 s, while in Group B the specimens were post-cured in a light-curing oven for 15 min before they were statically loaded with a steel ball.
Bar-shaped test specimens were prepared to measure the flexural properties of material combination using a three-point bending test (ISO 10477).

Results
Analysis of variance (ANOVA) revealed all specimens with a FRC substructure have higher values of static load-bearing capacity and flexural properties than those obtained with plain PFC (p<0.001).

Conclusion
The load-bearing capacity of all the specimens decreased after post-curing and water storage.
Restorations made from a material combination of FRC and PFC showed better mechanical properties than those obtained with plain PFC.

Prevalence, Intensity, and Correlation of Different TMJ Symptoms in Lebanese and Italian Subpopulations
Authors: Abou-Atme Youssef S. , Melis Marcello , Zawawi Khalid H. 
Published: July 2019

Abstract

Aim
The aim of this study was to compare self reported joint related temporomandibular disorder (TMD) symptoms in Lebanese and Italian dental and non-dental students and to detect any correlation between different symptoms.

Methods and Materials
A questionnaire was distributed in Sardinia (Italy) to dental and psychology students and in Lebanon to dental, physical therapy, and biology students to investigate the prevalence, intensity, and correlation of four temporomandibular joint (TMJ) symptoms.

Results
Prevalence of earache varied among the groups from 10.1% to 29.2%, ear stuffiness from 22.5% to 30.8%, TMJ pain from 13.2% to 21.2%, and TMJ sounds from 18.4% to 46.2%.

Discussion
Different prevalence and intensity of earache and TMJ sounds were found in the examined subpopulations diverse in cultural background and education. However, prevalence and intensity of ear stuffiness and TMJ pain were similar. Association between TMJ sounds and TMJ pain was detected in selected subpopulations, and correlation between one symptom on one side of the head with the same symptom on the contralateral side were noted suggesting most of these symptoms are bilateral.

Conclusion
The results of the study might be useful to anticipate the possible occurrence of associated symptoms or the same symptom on both sides of the head. Correlations with cultural background and education are difficult to establish.

Effect of Different Bonding Conditions on the Shear Bond Strength of Two Compomers to Bovine Dentin
Authors: Al-Nahedh Hend , Ateyah Nasrien 
Published: July 2019

Abstract

Aim
Despite the improvements to compomer materials, the bond strength of these materials remains inferior to .composite/resin bonding. systems and limits their clinical use. The purpose of this study was to evaluate the effect of acidic conditioning with phosphoric acid and Prompt L-Pop (PLP) on the shear bond strength of two compomers Dyract AP (DAP) and Composan Glass (CG) to dentin.

Methods and Materials
Sixty extracted bovine teeth were used to test the shear bond strength of two compomers to flat dentin labial surfaces. The dentin specimens were randomly assigned to six groups of ten specimens each: Group 1: DAP and Prime & Bond NT (PBNT); Group 2: DAP/PBNT with a 15 second dentin etch prior to bonding; Group 3: DAP placed with PLP adhesive; Group 4: CG and Compobond NE (CBNE); Group 5: CG/CBNE with a 15 second dentin etch; and Group 6: CG placed with PLP adhesive. The specimens were stored at 37°C with 100% humidity for 24 hours then mounted and sheared using an Instron Universal Testing Machine at a cross head speed of 0.5 mm/min. The results were recorded in Mega Pascals (MPa). The sheared specimens were examined under a light microscope, and the type of failure (adhesive, cohesive, or mixed) was recorded.

Results
The mean dentin shear bond strength value (MPa) for the groups was: Group 1 (11.6±3.9); Group 2 (13.2±3.3); Group 3 (12.4±2.0); Group 4 (13.0±4.3); Group 5 (19.3±3.7); and Group 6 (13.1±3.0). One way analysis of variance (ANOVA) and Tukey HSD post-hoc tests detected a significantly higher bond strength (P ≤ 0.003) for group 5. For groups 1, 3, 4, and 6, the mode of failure was mostly adhesive. When acid etching of dentin was performed (groups 2 and 5), cohesive fracture within dentin was the predominant mode of failure. Acid etching and the use of PLP significantly reduced the number of adhesive fractures and reduced variability in the shear bond strength results.

Conclusions
Acid etching significantly increased the shear bond strength of CG to dentin but did not affect DAP. The application of PLP resulted in a shear bond strength not statistically different from PBNT or CPNE. CG bond to dentin is improved with acid etching using phosphoric acid. However, PLP provided no significant improvement in the shear bond strength of DAP and CG.

Published: July 2019

Abstract

Aims
To assess reasons for third molar teeth extractions in a sample of Jordanian dental patients and to evaluate the association of extractions with other independent variables.

Methods and Materials
The study sample was comprised of dental patients in North Jordan who had third molar extractions. Data were collected from 36 dentists who were instructed to administer questionnaires to their adult patients undergoing third molar extractions and then to record the primary reason for those extractions. The data in this study was analyzed using a descriptive summary and chi square statistics.

Results
Dentists performed 810 extractions for 648 patients. The reasons for the extractions were: dental caries and its consequences about 42%, eruption problems 39%, periodontal diseases about 7%, and approximately 9% of extractions were a result of the dentist.s choice. The percentage of extractions due to dental caries significantly increased with increasing age. However, significant numbers of teeth were extracted due to eruption problems (51%-69%) in young adults. For 46+ year olds, 23% of extractions were caused by periodontal diseases. Extraction due to dental caries was distributed equally among the sexes. Persons with irregular tooth brushing and fewer dental visits had significantly more third molar teeth extracted due to caries and periodontal diseases compared to persons with regular tooth brushing and dental visits.

Providing Advanced Degrees in Dental Hygiene via Computer Mediated Distance Learning: A Model Program
Authors: Gadbury-Amyot Cynthia C. , Krust Bray Kimberly S. , Mitchell Tanya Villalpando 
Published: July 2019

Abstract
A chief concern regarding distance education for the health professions is quality of the experience. Distance education has the potential for expanding student access, providing individualized instruction, and promoting active learning among geographically separated members of learning groups. Students and professors who have participated in distance learning platforms have expressed concerns about technical problems, inability to interact in real time with each other, and other frustrations related to this type of delivery. The Dental Hygiene program at the University of Missouri-Kansas City (UMKC) has addressed these issues and enhanced an already successful program by putting the professor, a technologist, and the student in the same space, at the same time, in real time. This enhancement has substantiated the ability of distance education to provide instruction among geographically separated members of learning groups, making it a plausible solution to the shortage of educators in healthcare professions.
