Objective The purpose of this study is to identify the prevalence of uncomplicated and complicated crown fracture in permanent teeth. Study Design: Cross-Sectional Place and Duration: Nishter Institute of Dentistry, Multan between 2018-2020. Methods: There were 359 patients of both genders were presented with 525 permanent teeth. Patients were aged between 7–12 years. Patients detailed demographics age, sex, type of damage sustained, presence or absence of class II Div 1 were recorded after taking informed written consent from the authority. CPI probe was used to measure the degree of overjet as described by the 1997 WHO Basic Oral Health Survey Guidelines. Prevalence of complicated and uncomplicated crown fracture was calculated among traumatic dental injuries. Complete data was analyzed by SPSS 24.0 version. Results: Majority of the patient was male 200 (55.7%) were males and 159 (46.3%) were females. Mean age of the patients were 8.64 ±12.37 years. Falling was the most common cause of injury found in 195 (54.3%) cases followed by sports 110 (31.6%), RTA was found in 30 (8.4%) and physical violence in 24 (6.7%). Class II div 1 was present among 149 (34.2%) cases. Frequency of crown fracture was found among 43 (11.98%) cases in which complicated crown fractures were 16 (4.5%) cases and the rest 27 (7.5%) were uncomplicated crown fractures. Among 43 cases of crown fractures majority of the cases were males 27 (62.8%). Conclusion: We concluded in this study that the prevalence of crown fracture among TDI was 11.98% and majority among them was uncomplicated crown fractures. Preventive interventions are needed because of the high incidence of oral trauma. There needs to be a greater awareness among parents and children about the dangers of mouth trauma.

Aim: To evaluate the radiographical success of pulpotomy in cariously exposed mature permanent teeth using mineral trioxide aggregate. Methods:This Descriptive case series was conducted at the Department of Operative Dentistry, de’Montmorency College of Dentistry/ Punjab Dental Hospital, Lahore from December 2015 to December 2016.A total of 75 cases were included using non-probability consecutive sampling..Patients of both genders with age range from 15 to 26 years were considered. Performance of procedure and evaluation of success was done in terms of absence of periapical radiolucency on periapical radiographs.Data was entered and analyzed with IBM SPSS 20. Level of significance was kept at p-value ≤ 0.05 Results: Out of 75 patients, 41 were females and 34 were males.Mean age of patients included in this study was 20.5 ±3.60. Follow up at 6 months showed 92% success, with 69 cases showed absence of periapical radiolucency on periapical radiograph. There was no significant relation of success with age and gender of patient with p- value greater that 0.05. Conclusion: It is concluded from current study that the protocol of pulpotomy using Mineral trioxide Aggregate (MTA) in mature permanent teeth with carious exposure of pulp is encouraging and can be recommended for the treatment of mature permanent teeth with carious exposures.
