Background: Temporomandibular disorder (TMD) is a general term that refers to disorders associated with the temporomandibular joint (TMJ) and the masticatory muscles. Due to the complexity of the masticatory system, TMD symptoms may be caused by different physiological and/or psychosocial factors, such as malocclusion and occlusal interferences, alterations in the masticatory muscles, direct trauma to the jaw or TMJ, micro trauma caused by continuous parafunctional habits Aim: To determine frequency of anxiety and depression in temporomandibular joint disorders. Methods: Cross sectional study design was conducted in the Department of Oral and Maxillofacial surgery, Mayo Hospital Lahore for a period 6 months. a total 365 cases fulfilling inclusion criteria was enrolled in study from Oral and Maxillofacial surgery Mayo Hospital Lahore. Informed written consent was taken from patients and then their data according to variables in proforma was recorded. Anxiety and depression was measured by researcher himself according to operational definition. Results: The mean age of cases was 28.95 ± 6.71 years with minimum and maximum age of 18 and 40 years. In this study there were 185(50.68%) male and 180(49.32%) female cases. The mean Hospital Anxiety and Depression (HAD) score was 12.15±11.75 with minimum and maximum score as 0 and 42. Anxiety and depression was seen in 180(49.32%) of the cases while 185(50.68%) of the cases did not has anxiety and depression. Conclusion Through the findings of this study it is found that the frequency of Anxiety and depression is very much high. So we should formulate proper treatment strategy with the help of psychiatry department to cope this issue. No doubt it will help to improve their prognosis and better quality of life.

Introduction: Professional skills, training and experience is mandatory for removing impacted 3rd molars with aid of local/general anesthesia, sedation. As for symptomatic 3rd molars decision for removing is not difficult usually, but for removing asymptomatic 3rd molars decision is less clear & requiring good clinical experience. Objective: The objective this study was to determine frequency of lingual nerve damage during surgical removal of impacted 3rd molar Design: Descriptive cases series Study Setting: This study was conducted at Department of Oral and Maxillofacial Surgery, Sandeman Provincial Hospital Quetta over 6 months (April 10, 2018 till Oct 10, 2018). Materials and Methods: All 149 cases after approval of hospital ethical committee fulfilling the inclusion criteria were included in this study. After clinical and radiographic diagnosis of affected tooth like depth, position or any other difficulty, the surgical procedure was selected. An impacted tooth was labeled when it was failed to explode into the dental arch within the expected developmental window. After operation surgical sites of all patients were reviewed by the same consultant after 7 days. It was instructed to all patients that report any problem in lingual sensation; by clinical examination sensory deficits were recognized bilaterally. Results: The mean age of all cases was 29.82 ± 6.81 years with minimum and maximum age of 18 and 40 years. There were 83(55.7%) male and 66(44.3%) were females. According to types of impaction 22(14.8%) cases had Mesioangular, 10(6.7%) had Horizontal, 12(8.1%) had Vertical, 17(11.4%) had Distoangular, 14(9.4%) had Class I, 15(10.1%) had Class II, 11(7.4%) had Class III, 14(9.4%) had Class A, 16(10.7%) had Class B and 18(12.1%) cases had Class C. A total of 16(10.7%) cases had inguinal injury in this study. Conclusion: This study concludes that 10.7% cases had inguinal injury in this study. So, this procedure of impacted mandibular third molar is associated with minor but expected complications like the lingual nerve damage. Hence, preoperative and intraoperative consideration must be taken up to reduce this preventable complication. Keywords: Impacted teat, 3rd molar, surgery, complications, lingual nerve damage

Background: Mandibular fracture, also known as fracture of the jaw, is a sudden discontinuity through the mandibular bone. In the treatment of un-favorable mandibular angle fractures, 3D plating system was analogous to double miniplates Osteosynthesis. Over the last century, the indicators for closed vs. open reduction have shifted considerably. Objective: To compare the outcome of conventional miniplates versus 3-D miniplates for reduction of mandibular fractures Material & Methods Study Design: It was randomized control trial Setting: Department of Oral & Maxillofacial Surgery, Mayo Hospital, Lahore Duration: 6 months i.e. from 24-04-2017 to 24-10-2017 Data collection: 70 mandibular fracture patients were enrolled. The patients were split into two groups. Group A is treated with 3D plates technique and group B treated with conventional mini plate technique. After surgery patients were evaluated for plate failure or and at 1 month for occlusal discrepancy. All the data was entered and put in SPSS version 21. Results: In this study the mean age of the group A patients was 29.29±1.802 years whereas the mean value of age in group B patients was 35.69±11.65 years, male/female ratio of the patients was 1.05:1. Plate was successfully inserted in 100% patients by 3D mini-plate technique. The occlusal discrepancy was noted in 8(11.43%) patients (p-value=0.005). Conclusion: 3-D mini-plates for reduction of mandibular fractures is significantly more efficacious than to conventional mini-plates method Keywords: 3-D mini-plates, Conventional, Mandibular Fractures,
