Background:Cheiloscopy is a forensic investigation that deals with the examination of the system of furrows on the red part of human lips. Like fingerprint, lip print is also unique for every individual. But most of the crime-detecting agencies are unaware of the importance of lip print and it is not commonly attempted in identification of the suspects.Aim:The aim of the present study is to determine the predominant lip print pattern among Pondicherry population, India, and also to determine its uniqueness.Materials and Methods:The study comprised of 60 students (30 males and 30 females), aged from 17 to 25 years, from Pondicherry population, India. A dark-colored lipstick was applied with a single stroke and the students were asked to rub both the lips to spread the applied lipstick, after which a lip print was made on butter paper. The lip print was visualized with magnifying lens.Statistical Analysis:Percentage calculation method was used to identify the predominant lip pattern. One-sample T test was done to identify the statistical significance within the different types of lip pattern with P value <0.05.Results and Conclusion:The present study concludes that every individual has unique lip print and Type III appears to be the most predominant pattern in males, followed by the Type II, Type IV, Type I and Type V patterns. In females, Type II appears to be the most predominant pattern followed by the Type IV, Type I, Type III and Type V patterns.
INTRODUCTIONDirect pulp capping (DPC) is defined as the treatment of a mechanical or traumatic vital pulp exposure by sealing the pulpal wound with a biomaterial placed directly on exposed pulp to facilitate formation of reparative dentin and maintenance of the vitality of pulp.1 Calcium hydroxide has been the gold standard for this purpose.The alkalinity of calcium hydroxide causes superficial necrosis of exposed pulp. This necrosis acts as mild irritation and thus stimulates the pulp to form a reparative dentin bridge. The success rate of calcium hydroxide direct capping was 80.1% after 1 year, 68.0% after 5 years, and 58.7% after 9 years.2 The reason for failure over time is attributed to tunnel defects that form in the bridge. This fails to provide a permanent barrier and a ABSTRACT Background: Calcium hydroxide has traditionally been used as the pulp capping material for pulpal exposures in permanent teeth. The tunnel defects in the barrier and the tendency for dissolution, however, fails to provide permanent protection to the pulp. Light curable resin based cements have been introduced to enable a better marginal seal and lesser dissolution. The purpose of this study was to compare and evaluate the response of human pulp following direct pulp capping with the new resin based Calcium silicate (TheraCal LC) and Calcium hydroxide with hydroxyapatite (Septocal LC) cements compared with calcium hydroxide (Dycal). Methods: 72 intact human premolars scheduled for orthodontic extractions were exposed to direct pulp capping procedures using three different pulp capping agents. Teeth were randomly divided into 3 groups, Group A: Dycal, Group B: TheraCal LC, Group C: Septocal LC. The teeth were extracted at the end of 15 and 40 days' and were evaluated histologically. They were scored for reparative dentin formation and inflammatory response. Inferential statistics was done using Chi square test. Results: Majority of the specimens in all three groups at the end of 15 days' showed partial to lateral deposition of hard tissue. There was continuous deposition of hard tissue and severe inflammatory response at the end of 40 days' in Dycal. There was partial deposition of hard tissue and reduced inflammatory response at the end of 40 days' in TheraCal LC and Septocal LC. However, the results were not statistically significant between the three groups at two different time periods. Conclusions: Light cured, Calcium silicate (TheraCal LC) and Calcium hydroxide with hydroxyapatite (Septocal LC) cements were as effective as calcium hydroxide (Dycal) in inducing the formation of reparative dentin and evoking inflammatory response.
Peripheral Ameloblastoma (PA) is a benign odontogenic tumor, arising from the cell rest of Serres, reduced enamel epithelium and basal cells of the surface epithelium. Peripheral ameloblastoma is a rare odontogenic neoplasm occurring commonly in the mandibular gingiva. PA clinically resembles other peripherally occurring lesions like pyogenic granuloma, peripheral ossifying fibroma, peripheral giant cell granuloma, and squamous papilloma. The recurrence rate of PA is 16-19% which demands a straight follow up. We report a case of recurrent peripheral ameloblastoma occurring in a 72-year old male located in the mandibular lingual gingiva in relation to the 44, 45 element's regions. The patient had a primary lesion excised from the same site 6 years before which was diagnosed as ameloblastoma.
Oral cancer is the sixth most common malignancy in the world. Oral cancer is of major concern in Southeast Asia primarily because of the deleterious habits such as smoking, betel nut chewing and alcohol consumption. Despite recent advances in cancer diagnoses and therapies, the survival rate of oral cancer patients has remained at a dismal 50% in the last few decades. This paper is an overview of the various etiological agents and risk factors implicated in the development of oral cancer.
Objective Literature revealed that oral health status and awareness about oral hygiene measures of Narikuravar tribes were very poor. There was also an increased prevalence of tobacco usage among this population. Considering this, incidence and prevalence of oral precancerous and cancerous lesions are expected to be high in this population. Surprisingly, the literature search revealed a lack of data on the awareness, knowledge, and prevalence of oral cancer and precancer in this group. The primary objective of this survey is to assess knowledge, awareness and attitude toward oral precancer and cancer among the Narikuravar tribal population in Pondicherry state. Materials and Methods This questionnaire survey is a part of the Model for Oral Cancer Eradication project conducted among the Narikuravar population in Pondicherry, which is funded by Indian Council of Medical Research (ICMR). A total of 153 participants were recruited for the survey. A prevalidated questionnaire was used for the survey. Results The results indicated that 47% of the participants were aware of what is oral precancer and cancer. As much as 62% knew that chewing tobacco causes oral cancer and 44% thought that the growth of tissue in the mouth could be a sign of oral cancer. Almost 100% did not think that the presence of a red lesion, white lesion, or limitation of mouth opening could be signs of cancer or precancer. Only 16% thought that oral cancer is preventable. Conclusion Awareness about oral cancer and precancer is inadequate among the Narikuravar population of Pondicherry. Majority of the population is not aware of the risks, signs, or treatment options of oral precancer and cancer. The National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) identified the people’s knowledge gaps, and improving awareness is one of the strategies of the program.
