Published: February 2023

Background and Objectives:
According to the global cancer situation, which is very alarming, with over 10 million new diagnoses and more than 6 million deaths each year globally, cancer is one of the most prominent causes of morbidity and mortality today. One of the cancers is oral cancer. Oral cancer is the irregular development of malignant cells in the oral cavity. The study's objective was to decide the mortality of cross-tabulation among patients treated for oral carcinoma from Hospital Universiti Sains Malaysia (USM), Kelantan, Malaysia.

Materials and Methods:
This chapter summarizes the medical history for 7 years from January 2011 to December 2018 of patients who have been treated for oral carcinoma in the Hospital USM, Oral and Maxillofacial Surgery (OMFS) Unit. Each patient's complete medical record was checked, and data gathered were based on age, gender, site lesion, clinical diagnosis, and mortality. Version 26.0 of the SPSS software was used to evaluate the correlation and distribution of patient survival.

Results:
This was a retrospective cross-sectional review of the medical evidence of 117 patients infected for oral carcinoma at OMFS (Hospital USM). Sixty-seven (57.26%) of the patients were male and fifty (42.74%) were female. Patient age ranged from 25 to 93 years. Malay has the highest prevalence (85.5%) in oral carcinoma, followed by a second ethnic group, Chinese (7.7%). The result indicates that the majority of oral carcinoma patients were over 60 years old.Cases of oral squamous cell carcinoma have proved to be the most prevalent malignant tumour in the mouth cavity. The largest number of cases collected is 91% of the data collected. Mucoepidermoid carcinoma (10%) is the second most common small salivary gland tumor.

Conclusion:
OSCC is the most prevalent kind of oral cancer. According to the data review, the most popular site for oral cancer is the tongue.

Published: February 2023

Background:
Cosmetic defects after the major orofacial disease corrections may have an effect on the overall well-being of the patient. Head-and-neck cosmetic surgeries after a major episode of oral cancer impact the functional ability of the individual in several ways. In general, two types of flap are used in reconstructive surgery: microvascular free flaps and regional pedicle flaps. In socioeconomically poor countries like India, bilobed pectoralis major myocutaneous (PMMC) flap has been seen as a mainstay in facial reconstructive surgeries.

Materials and Methods:
The present study was conducted on 100 individuals with oral neoplasm who underwent resective surgery had a soft-tissue defect. All the complications that arose after reconstructive surgery were noted. Simple proportions were recorded.

Results:
Majority of the individuals had the buccal mucosa as the common site of oral neoplasm, and the tumor nodes and metastases staging was I + II. One individual sustained total flap necrosis. Wound infection and dehiscence were the most common complications.

Conclusions:
PMMC is best proven for flap reconstruction in oral neoplasm cases. It is established to be effective with good acceptability and very few complications. Due to these reasons, in spite of the known advances in facial reconstructive surgeries, this technique is widely followed in developing countries.

Published: February 2023

Introduction:
In the facial bones, the angle of the mandible is the common site of fractures. Furthermore, it is the site with the highest number of complications after fracture and hence needs an efficient fixation. The right approach is still debatable for the angle fractures. In the light of these factors, we evaluated the transoral and the transbuccal approaches for the treatment of fractures at the angle of the mandible.

Materials and Methods:
Twenty patients were equally divided into two groups of transoral and transbuccal methods. The parameters such as ease of access, surgical time, occlusion, postsurgical infection, fracture gaps, scarring, and complications were noted, and the values that were compared were statistically analyzed. P < 0.05 was considered statistically significant.

Results:
No significant variations were seen in the variables such as ease of access, occlusion, postsurgical infection, and fracture gaps. Surgical time was significantly less for the transoral method. Negligible scarring was noted in the transbuccal method.

Conclusion:
Although both the methods were comparable, the transbuccal approach was more efficient for the mandibular angular fracture treatment.

Materials and Methods:
This was a cross-sectional web-based questionnaire survey conducted among orthodontist in India. The pilot study was conducted to estimate the sample size and final sample size is 263 participants. The predesigned and validated, self-administered, structured 10 questions related to the impact of an orthodontist and their orthodontic practices during and after COVID 19 are used. The statistical analysis was done using Statistical Package for Social Sciences SPSS (V 22.0) the frequency distribution was computed.

Results:
The result showed that 81% orthodontist were reported that routine orthodontic treatment was disturbed due to this COVID 19 lockdown, about 79.1% reported hospital/clinic was closed due to lockdown with a duration of more than 1 month. Still, 64.6% orthodontist handling their orthodontic emergencies through telecommunication and 47.9% of orthodontist received a complaint about fixed appliance among all other appliances. Due to the current situation, 41.4% orthodontist suggested 3–6 months' period required to normalize the current situation and 66.9% agreed that there will be decline in orthodontic treatment need after COVID 19.

Conclusion:
Owing to the high virulence activity, elective procedures have been postponed and can manage a patient through virtual teleconsultation. Reassurance of the patient is needed regarding prolonged treatment duration due to this COVID 19 pandemic.

Published: February 2023

Introduction:
The success of any restoration depends on the marginal seal. The adaptation of castings, luting cement, and the surface structures of the margins are all important factors in achieving marginal seal.

Aim:
The aim of this study was to evaluate the vertical marginal discrepancy of cast copings obtained by employing conventional casting technique with two different base metal alloys with two different finish lines before and after porcelain firing.

Material and Methods:
A total of forty wax copings were fabricated with stainless steel die assembly and divided into four groups with ten specimens for each metal and each finish line. Measurements were recorded from coping margin to the stainless steel die margin for vertical marginal gap recordings. Each metal coping was finished, and porcelain application was completed. Copings with porcelain were placed on their respective dies, again subjected to the same measuring microscope for checking the vertical marginal discrepancy by the same operator and results.

Results:
The results of the present study showed that the mean vertical marginal gaps of all the cast copings obtained in each group (G1–G8) were within clinically acceptable limits. The mean vertical marginal gap of G1 was 135.36 ± 2.30 μm, G2 was 67.22 ± 4.25 μm, G3: 39.47 ± 2.98 μm, G4: 71.00 ± 3.97 μm, G5: 109.57 ± 2.98 μm, G6: 109.57 ± 2.98 μm, and G8: 114.58 ± 2.40 μm.

Conclusion:
The difference in the vertical marginal gap of cast copings obtained in different groups was statistically highly significant at 0.005 level, while the difference in the vertical marginal gap of cast copings obtained at different points was statistically nonsignificant.

Published: February 2023

Introduction:
Periodontitis is inflammation of periodontium. Periodontal disease is associated with various risk factors among which female hormonal alterations such as menopause have been found to be connected with periodontal breakdown and osteoporosis in women. The aim of this study was to determine the periodontal status in pre- and postmenopausal females.

Materials and Methods:
In this study, 60 female patients were analyzed aged between 40 and 60 years. Group 1 (test) comprised 30 premenopausal women with/without chronic periodontitis and Group II (control) comprised 30 postmenopausal women with/without chronic periodontitis. After recording clinical parameters, the scores were provided using Orthopantomograph for each patient. Paired t-test was applied for intragroup comparison and independent sample t-test was applied for intergroup comparison. The value of P < 0.05 was considered statistically significant.

Results:
The mean plaque index, gingival index, calculus index, pocket probing depth, and clinical attachment loss scores in the premenopausal group were less as compared to postmenopausal group. Both the groups showed statistically significant differences with T=15.28 and P = 0.01.

Conclusion:
Postmenopausal women are more susceptible to periodontitis. Hence, precaution and initial management of oral diseases should be the utmost priority in women's health. The effect of sex hormones can be reduced with regular dental examination, maintaining good oral hygiene, and hormonal replacement therapies.

Published: February 2023

Aim:
The aim of this study was to conduct a cross-sectional questionnaire-based survey concerning the practice of occlusal splint for treating temporomandibular disorders (TMDs) by the dental practitioners of Jabalpur.

Materials and Methods:
A questionnaire containing questions on diagnosis, treatment, and management of TMD was given to a total of 157 general dental practitioners in Jabalpur. The responses were collected; data analysis was done by Chi-square test.

Results:
Of the General Dental Practitioner's, nearly 78% of participants did not attend any continuing dental education on TMD per year. More than 10 years of experience (82%) was associated with increase in positive response for treatment of TMD patient. Both the diagnosis and treatment of TMD patient were done using combination methods. The duration of splint use was considered patient dependent (42.27%) irrespective of the years of practice. Soft splint was most commonly employed for treatment, and fabrication of splint was done on hinge and mean value articulator.

Conclusion:
The knowledge of occlusal splint by general practitioners was found to be insufficient for treating TMDs.
Role of Facial Index and Odontometric Parameters in the Establishment of Stature and Gender of Individuals
Authors: Gopinath Tarunikaa , Ganesh Suryaprakash , Subramani Vijaya Nirmala 
Published: February 2023

Background:
Dental anthropology is an important aspect of bioarchaeology and forensic anthropology. In forensic anthropological studies, identifying an unknown individual from a mangled and decomposing body is a challenging task. Cranial remains are the only critical clues available for personal identification. Age, sex, and stature are significant parameters in establishing the identity of an unrecognized individual. Stature is the natural height of the individual in an upright position. Stature can be estimated from various parts of the body such as long bones, short bones, and skull. Few studies conducted in specific population have established a correlation for predicting stature from cephalometric and odontometric parameters. Thus, the present study was conducted to determine stature and gender based on cephalometric and odontometric parameters in the population of Tamil Nadu.

Aims:
The aim of this study was to investigate the possibility of predicting the stature and gender of an individual based on odontometric measurements, facial height, and bizygomatic width.

Materials and methods:
A total of seventy individuals in the age group of 18–24 years were selected for the study. The facial height, bizygomatic width and length, mesiodistal and labiolingual diameter of clinical crown of maxillary central, lateral and canine teeth of both the right and left quadrants were measured. The values were analyzed statistically. Through this analysis, regression equations for estimation of stature from odontometric and facial index were derived.

Results:
Pearson correlation test was carried out to establish a correlation between the stature and the measured parameters. Regression analysis was carried out to establish stature from the odontometric and facial index of the individual. The regression equations were used to get estimated stature in the same sample of volunteers from which regression equations were obtained. Tabulated results showed a probable correlation between various parameters.

Conclusion:
In our study, a positive correlation between cephalometric measurements, gender, crown length of permanent left central incisor, and combined mesiodistal diameter of permanent maxillary anteriors with stature was found. This can be used as a supplementary method for estimating the stature of unknown human bodies.

Authors: Singh Rajsandeep , Lehl Gurvanit , Hussain Arshad Bin , Abhang Tejal Nivrutti , Kulkarni Manisha Mangesh , Elagib Mohamed Fadul A. , Tiwari Rahul V. C. 
Published: February 2023

Background:
With increase in exposure to titanium in daily life and its use in medical procedures, there is a greater chance for developing titanium hypersensitivity. Our aim and objective is to examine whether patient patients with titanium implants had a greater incidence of titanium hypersensitivity or not. Titanium is widely considered to have good biocompatibility. A passivating surface layer of TiO2 is formed when exposed to air which gives it good corrosion resistance. These properties along with its high strength, lightweight, and improvements in smelting technologies have led to its widespread use as an intraosseous and periosteal implant in dentistry and orthopedics.

Materials and Methods:
Only case–control studies were used for the meta-analysis. Studies with a sample size of <5 were excluded. Cutaneous and epicutaneous tests were used in the study.

Results:
Three studies met the inclusion criteria. Titanium hypersensitivity is more prevalent in patients with titanium implants.

Conclusions:
It is also used in a variety of medical devices such as pacemakers and insulin pumps. Moreover, our external exposure to titanium is increasing. It is used in aerospace, chemical, and automobile industries. It is also used in jewelry, home furnishings, and in making sports and marine equipment. Titanium implants increase the possibility of developing titanium hypersensitivity, and thus, it should be considered as a major factor in unexplained implant failure where other causes have been excluded.

Authors: Das Lopamudra , Panigrahi Ashok Kumar , Biswal Sashi Bhusan , Bisoi Debasis 
Published: February 2023

Background:

Nyctanthes arbor-tristis (NAT) is an ornamental garden plant traditionally used for treating many diseases such as helminthiasis, arthritis, and malaria.

Aims:
The aim of this study was to validate the ethnobotanical uses of the antimalarial activity of leaves of NAT by in vivo tests.

Materials and Methods:
Leaves of NAT were identified and authenticated and phytoconstituents of NAT were identified. The antimalarial activity of NAT was studied in in vivo for its schizonticidal activity, repository activity, and curative tests in Swiss albino mice by using Plasmodium berghei (ANKA).

Statistical Analysis Used:
One-way ANOVA was done for comparison of different groups followed by post hoc analysis (Tukey-Kramer multiple comparison tests). Level of significance was at P < 0.05.

Results:
The mean schizonticidal activity of NAT increased from 14.21 to 46.15 (P < 0.01) with doses ranging from 100 to 200 mg/kg compared to 67.29 with that of chloroquine (CQ). The repository activity with NAT doses 100–200 mg/kg increased from 12.91 to 42.85 (P < 0.01) compared to 78.79 in pyrimethamine 1.2 mg/kg/day. In Rane's test, there was chemosuppression in range of 55.50–65.02 (P < 0.01) with NAT in doses of 100–200 mg/kg compared to 74.15 with that of CQ 5 mg/kg.

Conclusions:
The antiplasmodial activity of NAT might be like that of artemisinin by producing oxidative stress mostly due to the iridoid glycosides. The active phytoconstituent(s) responsible may be tested individually or in combination both by in vitro and in vivo studies to identify the active chemical ingredient.
