Aim: The aim of the study was to investigate the incidence and configuration of C-shaped root canals in mandibular second molars in North Indian population using clinical and radiographic method and to compare the relative efficacies of these two methods. Methods and Material: 500 patients with mandibular second molar teeth scheduled for root canal treatment over a period of 1.5 years were examined during 2018-2019. C-shaped root
canals were determined by clinical examination using modified Melton's criteria and by radiographic method using Fan’s criteria.
Results: Incidence of C-shaped root canals was found to be 6.80% using clinical method and 5.20% using radiographic method. Females had greater (9.4%) predilection than males (4.69%) clinically. There were only 19 teeth in which presence of C-shaped root canal were confirmed both clinically and radiographically

 Aim: The purpose of our research was to study various patterns as well as incidence of mandibular population amongst Indian population. Methodology: The medical records of 1842 patients with mandibular fractures treated
over a 3 years period were identified and analyzed supported age, sex, mechanism of trauma, seasonal variation, drug/alcohol abuse, number and anatomic location Results: 464 Patients who were in age range of 7 to 89 years participated in the study. The highest incidence (37.5%) of mandibular fractures was in the age group of 21–30 years. Most prominent cause for mandibular fracture was due to road traffic accidents which accounted for 68.8 % of all cases followed by free falls as well as assault cases. It was observed that parasymphyseal fracture was the most common site affected in mandible and the least affected was the angle of mandible. Mandibular angle
fractures were found mostly to be related to assault victims. Conclusion: The mechanism of injury correlates significantly with the anatomic location of fracture and knowledge of those associations should guide the surgeons for appropriate and timely management.

Globally, oral cancer is the sixth most common cancer and it is associated with a mortality
rate up to 50%. Oral cancer usually encompasses tumours derived from the lips, anterior
two-thirds of the tongue, buccal mucosa, hard palate, the floor of mouth, upper and lower
alveolar ridges, retromolar trigone, and sublingual area. An approximate age-standardized
to world population (ASR (W) for oral cavity and lip cancer according to the World Health
Organization (WHO) the topmost is South East Asia with incidence of 6.4 per 100000,
followed by Europe and East Mediterranean (4.6 cases per 100000), America (4.1 per
100000), Africa (2.7 per 100000), and Western Pacific area (2.0 per 100000).Oral
squamous cell carcinoma has multifactorial pathogenesis which includes smoking, alcohol
consumption, and HPV and others. Oral cancer has multifactorial etiology, mainly
smoking, tobacco, alcohol consumption, betel quid chewing and high-risk human
papillomavirus (HPV). Worldwide, the prevalence of HPV infection is 3% in oral cavity
cancer and has a significant role in the management of oral squamous cell carcinoma
(OSCC) as HPV-related oral cancers have shown better prognosis.
The risks of oral cancer in many developing countries had increased mainly by the habits
of using betel quid chewing, tobacco and alcohol consumption.Human papillomavirus is a
major concern and a public burden in a clinical setting all over the world. The sites
frequently involved in HPV related cancers are tonsils and base of the tongue.

Multidisciplinary management is essential when the canine fails to erupt on time. This requires combined surgical and orthodontic intervention. Good periodontal status is necessary for the positive outcome of treatment. Hence the objective of this study was to evaluate the incidence of gingival recession in disimpacted canines. A retrospective study was conducted. Data collection was done through reviewing 86000 patients who had visited a hospital in Chennai from June(2019) to March(2020). A total of 6 patients who had undergone disimpaction of canine were evaluated. Data such as age, gender, site of impaction, presence of gingival recession were noted. The data was analysed statistically through IBM SPSS software. The study group belonged to the age group ranging 13-21. Disimpaction was performed higher among males(66.6%) compared to females. Among the samples, about 57.14% of canines were palatally impacted. No gingival recession was seen in the study sample. The incidence of gingival recession in the disimpacted canines was not statistically significant and did not reach clinical significance due to very less sample size.

AimThe aim is to assess the knowledge, attitude and practice on the incidence of pulp stones in maxillary molars among endodontists and general practitioners.IntroductionPulp stones are discrete calcified masses found in the dental pulp tissue or embedded into dentin. Based on their radiographic features, they can be classified into true and false which are located more often in the coronal region of the tooth. True pulp stones are made up of dentine and lined by odontoblasts, whereas the false pulp stones are formed from degenerating cells of the pulp that get mineralized. Materials and MethodsThe sample size is 102 people and a random sampling method is used to minimise bias. Internal validity was a pre tested questionnaire and external experiment and cross verification with existing studies was performed. Data analysis was done in SPSS and Statistical test used is chi square test and dependent variables are demographic data such as gender and experience and independent variables are pulp stones incidence and knowledge.ResultsFrom this survey it was found that 70% were aware about the types of pulp stone, 62% were able to diagnose pulp stones radiographically and 60% encountered pulp stones rarely in maxillary molars.Conclusion
Within the limitations of the study , the prevailing knowledge in regard to the prevalence of pulp stones among endodontists was high when compared to the general practitioners. More awareness can be created among general practitioners about pulp stones. Furthermore, the existing Attitude and practice among respondents was high among endodontists and general practitioners when compared to knowledge.
