Introduction: Temporomandibular Joint (TMJ) has been a controversial topic in Oral and Maxillofacial Surgery speciality especially regarding temporomandibular joint disorders and internal derangement of articular disc. The aetiology behind it has been related to the anatomic variations of the disc and its impact on the functioning of the articular disc. To understand such anatomic variation, the study has been conducted that will help future maxillofacial surgeon’s in designing accurate prosthetic articular disc that will improve the overall mechanics of the functioning of the prosthetic disc. Aim: To analyse the morphometric variations of the intra-articular disc in terms of circumference of the disc, perforations and their thickness within the disc in cadavers. Materials and Methods: The present observational study was carried out on cadavers in the Department of Anatomy. SBKS Medical College and Research Centre, Sumandeep Vidyapeeth University, Gujarat, India. The study was done from January 2017 to October 2018. Temporomandibular joints were dissected bilaterally from 10 human cadavers, i.e., 20 articular discs. The disc was removed and was measured with the help of thread, vernier callipers and standardised metallic scale and the circumference and thickness in the disc were evaluated. Descriptive statistical test was used and Chi-square test was applied. Results: Mean thickness of disc, both in males as well as females ranged from 1.4-2.0 mm in the Posterio-Medial (PM) and Posterio- Lateral (PL) region, while in Anterio-Medial (AM) and Anterio- Lateral (AL) region it ranged from 1.6-1.8 mm. Maximum length of disc ranged from 12-13 mm in anterio-posterio dimension while in Medio-Lateral (ML) it was 22-23 mm. Conclusion: The study gives an indepth knowledge about the various morphometric variations of articular disc and also shows its impact on the functioning of the disc. The study also directs maxillofacial surgeons to design prosthetic articular disc with greater accuracy and anatomical knowledge so that the procedures like surgical replacement of the disc can be carried out with greater potency and efficacy for the betterment of the patient.

The temporomandibular joint (TMJ) is prone to a number of disease states involving any one of its anatomical components. The current favoured term for problems associated with the TMJ is ‘temporomandibular disorder’ (TMD). TMD is one of the most common orofacial pain conditions. Patients will present to GPs and general dental practitioners as well as directly to accident and emergency, typically for referral to Oral and maxillofacial surgery, due to either significant acute pain or chronic pain that can no longer be tolerated. Common features of TMD include pain in the face and preauricular area, restricted jaw movement, and noise from the TMJs during jaw movements. TMD can coincide with poor general health, psychological co-morbidities such as depression and often affects quality of life.

OBJECTIVES:To evaluate the prevalence and severity of TMDs in house officers and postgraduate students belonging to public and private sector medical and dental colleges.METHODOLOGY:This was a cross sectional study carried out from July 2018 to September 2018 in Department of Oral and Maxillofacial Surgery, Sardar Begum Dental College and Hospital, Peshawar. After approval from ethical committee Gandhara University, an informed consent was obtained and Fonseca questionnaire was used to evaluate TMDs from 320 subjects who voluntarily want to participate in the study; selected with equal genders from public and private sectors medical and dental hospitals, Peshawar. Those who have musculoskeletal, neurological, systemic problems and orthodontics treatment subjects were excluded from the study.RESULTS:The age range selected was 22-32 years and the mean age presentation was 26.5 ± 3.4 years. Results showed that female postgraduate residents of private sector consider themselves tenser (18.8%) than others. 70.17% female house officers of private sector have noticed TMJ clicking and 83.17% of male house officers clenched or grind their teeth than others.CONCLUSION:The study concluded that mild and moderate TMDs are more common in-house officers and postgraduate residents.KEYWORDS: Temporomandibular Disorders, Prevalence, Temporomandibular Joint, Fonseca’s Anamnestic Index, Cross-Sectional Study

Introduction: Temporomandibular joint disorders (TMDs) are among the most common disorders in the maxillofacial region which usually present with joint pain, decreased jaw mobility, joint clicking, headache, tinnitus, neck pain etc. There are different modalities of treatment used for the TMDs. These include some conservative and surgical procedures. The main aim is to improve the jaw function and reduction of joint pain. Arthroscopy is a modern diagnostic and effective therapeutic procedure for the TMDs. Objective: To assess the outcome of arthroscopic lavage of Temporomandibular Joint (TMJ) in terms of improvement of jaw function and joint pain in patients suffering from TMDs. Materials and Methods: This prospective study was carried out at the department of Oral and Maxillofacial Surgery, Military Dental Centre, Combined Military Hospital of Dhaka Cantonment from 01 October 2014 to 31 March 2016. Patients were selected consecutively having TMDs and unresponsive to conservative nonsurgical therapy. Total thirty patients of TMDs were selected for study and all the patients were treated with arthroscopic lavage. Objective data were collected including, inter incisal opening, lateral excursion, deviation on opening, tenderness on palpation. A questionnaire in the form of visual analogue scale relating to pain, joint clicking and Jaw mobility were completed by each patient at 1 week,1 month and 6 months post operatively. Results: Among thirty patients, 10 patients were male and 20 patients were female. Mean age of the patient was 42.6±5.79 years. Maximum patients were in the age group of 41-45 years. There was statistically significant improvement in maximum incisal opening and pain score. There was also reduction in Joint clicking and tenderness in maximum patients. Conclusion: The findings of the present study suggested potential utility of arthroscopic lavage in the management of TMDs. Journal of Armed Forces Medical College Bangladesh Vol.12(1) 2016: 88-93

Those dual qualified in oral and maxillofacial surgery (OMFS) in Australia have a scope of practice that includes dentoalveolar surgery, facial fractures, craniofacial deformities, salivary gland disease, temporomandibular joint disorders, and the treatment of oral and facial cancers with reconstruction. This differs from other countries such as the UK, the US, France and Brazil, which can lead to complexities of interaction when internationally trained health professionals, who may be unaware of this wide breadth of practice, are the ‘gatekeepers’ at tertiary health facilities. 1 – 3

<p><strong>Objective:</strong> To verify the level of agreement among different indexes used to achieve the prevalence of Temporomandibular Disorders (TMD). <strong>Material and Methods</strong>: One hundred one dental students were selected by a randomized process. TMD were evaluated by the Fonseca’s Anamnestic Index (FAI), Helkimo’s Clinical Index (HCI), and the Research Diagnostic Criteria for TMD (RDC/TMD). Data was analyzed using Chi-square and Kappa tests, considering a significance level of 5%. <strong>Results:</strong><em> </em>HCI showed the highest prevalence of TMD, and the comparison between RDC/TMD, FAI, and HCI showed low agreement (k=0.17 and k=0.35 respectively). Most individuals presented mild TMD for both FAI and HCI indexes. A moderate correlation for TMD severity was obtained (k<sub>w</sub>=0.53) between FAI and HCI, and a high sensitivity and low specificity were observed for both diagnosis when compared to RDC/TMD. <strong>Conclusion</strong><em>:</em> The prevalence of TMD may vary significantly depending on the index used for its diagnosis, which may lead to a large number of false positives and overtreatments.</p><p><strong> </strong></p><p><strong>Keywords: </strong>Epidemiology; Prevalence; Temporomandibular joint; Temporomandibular joint disorders; Young adult.</p>

Pre-prosthetic surgery is part of the oral and maxillofacial surgery, which concerns restoration of facial form and oral function. Pre-prosthetic surgery is a surgery done to obtain a better anatomic environment and to provide proper supporting structures for denture construction. The aim of this study was to analyse the various pre-prosthetic surgeries performed in a private dental institution. In this retrospective study, digital case records of all patients who underwent pre-prosthetic surgeries in Saveetha Dental College and Hospital from June 2019 to March 2020 were reviewed. Demographic details of patients and types of pre-prosthetic surgeries performed were recorded from digital case records. Retrieved data was analysed using IBM SPSS Software Version 23.0. Descriptive statistics and tests of association for categorical variables by Chi square tests were done and results were obtained. P value <0.05 was considered statistically significant. In this study, we observed that pre-prosthetic surgery was more commonly performed in the age group of 51-60 yrs (23.3%). Pre-prosthetic surgeries were done more in males than females. The most common type of pre-prosthetic surgery was valvuloplasty (62.2%), followed by frenectomy (20.7%). Statistically, a significant association was found between pre-prosthetic surgery and age group; pre-prosthetic surgery and gender; pre-prosthetic surgery and quadrant involved (p<0.05) Within the limits of this study, it can be concluded that the most common pre-prosthetic surgery performed was valvuloplasty. Pre-prosthetic surgery was performed more in males and the age group of 51-60 years, mostly in the third quadrant.
