A BSTRACT Introduction: The third molar is the most frequently impacted tooth with a frequency of occurrence generally reported to be from 18 to 32%. It is considered impacted when its eruption into normal functional occlusion has been interfered with by other teeth, overlying bone or soft tissue and when it is not fully erupted by its expected age of around 20 years. Racial differences affect the pattern of impaction. There is a lacunae of literature on the pattern of mandibular third molar impaction in Tamil population. Aim: To investigate the prevalence of pattern of third molar impaction among the population in Madurai. Materials and Methods: A retrospective cohort study was conducted. The first 1000 OPGs (Orthopantamograms) were taken at the Department of Oral Medicine and Radiology, CSI College of Dental Sciences and Research from August to December 2018 of Madurai population aged between 20 and 40 years old. Data include angle, level and position of impaction, proximity to inferior alveolar nerve and dental caries in second molar and/or third molar. Results: The average age of subject with mandibular third molar impaction is 30.5 years. The most common occurring mandibular impaction is mesioanglar (60%), Level A (71%), Class II (50%) without involving the inferior alveolar nerve (33%) and dental caries in 20% of second and/ or third molar. Conclusion: Mandibular third molar impactions are one of the common developmental condition in this modern civilization. Assessing the third molar and prognosis of its eruption is mandatory for better patient management because of numerous complications associated with unerupted third molar.
A BSTRACT Introduction: Maxillofacial injuries are more prevalent in road traffic accidents (RTAs). The incidence of RTAs tends to vary with geographical location, socioeconomic status, religion etc. Aim: The main aim of this study is to determine the pattern and prevalence of maxillofacial injuries reported to our institution. Materials and Methods: Data were obtained from medical records of the patients from January 2007 to December 2017 reported in CSI College of Dental Sciences and Research, Madurai, Tamil Nadu were retrieved and analyzed. Data include age, gender, etiology, site of injury, anatomical site associated injuries and their management were recorded and analyzed with STATA software version 14 (StataCorp LLC, College Station, TX, USA). Results: Maxillofacial injuries occur more commonly in 2nd and 3rd decade (40.44%) with mean age of 32.58 ± 11.15 years. RTA (77.21%) and alcohol influence (51%) were considered as the most common cause of maxillofacial injuries and was statistically significant. Mandible (44.85%) was most commonly involved and 62.5% required a surgical intervention. Conclusion: RTA with mandibular fracture is predominant in men between the age group of 20-30 years. Expansion in road network, increase in motorization, alcohol consumption and urbanization in developing countries had accompanied with rise in RTAs. Thus the use of safety devices and educating people by conducting preventive camps about traffic rules will reduce the number of RTA.
Objective: The conventional treatment for Anterior Maxillary Vertical Excess (AMVE) is surgical reduction and rigid fixation which has low patient acceptance. However, intrusion of some selected AMVE cases can be achieved with minimal intervention using micro plate anchorage, thus expediting and simplifying their management. The present paper demonstrates the efficacy of microplate anchorage in the intrusion of anterior maxilla. Methods: A total of 7 patients (2 males and 5 females) in the age group of 13–43 years were treated for anterior maxillary vertical excess. Anterior maxillary intrusion was carried out using two hole microplates anchored bilaterally at the naso maxillary buttress and closed coil spring attached to the arch wire. The activation was carried out at monthly interval. Results: The mean duration of surgical procedure was 18.4 minutes and the mean duration for intrusion was 4.86 months (3–7 months). The patients compliance were overall good and the average amount of intrusion achieved was 4.14 mm. All the patients were satisfied with post treatment smile. Conclusion: The result of this study elucidates that intrusion using micro plates is an easy, efficient, safe and cost effective option in the management of AVME. It is less invasive with acceptable clinical and radiographic outcome. Careful case selection is needed for achieving satisfactory result and smile.
