ABSTRACT
BACKGROUND: Periapical lesions can be appreciated in the teeth that have underwent root canal treatment leading to more complications. Radiographic as well as histological evaluation is important for definitive diagnosis. AIM: The aim of this study was to examine the histology of constant periapical radiolucent lesions that are associated with root canal treated teeth and also to find association between histological findings and radiographic size of lesion as well as existence or nonappearance of a radiopaque lamina. MATERIALS AND METHODS: The study included 60 incisors and canines allotted for apical microsurgery. Two observers studied the diameter of periapical radiolucent lesions and the existence or nonappearance of radiopaque lamina. During apical microsurgery, biopsy specimens were collected and after tissue processing oral pathologist examined the specimen under a light microscope. Histological features of the specimen were taken into consideration, and the diagnosis of abscess, cyst, granuloma, and scar tissue were given. Pearson's chi-square test was used to study the established relationship between histological diagnosis and lesion size. RESULTS: Results indicated that 68.33% of lesions were granulomas, 23.33% were cysts, 5% were abscesses, and 3.33% were scar tissue. CONCLUSION: According to histological results, most of the lesions in this study were granulomas, followed by cysts. Abscesses and scar tissues were rare.
ABSTRACT
INTRODUCTION: Very little is known about the hard to reach tribal communities in India and one such community is a primitive hidden and isolated tribe group of Bharia people in Patalkot. Their health problems need special attention as they have very limited access to health care. The aim of this study is to assess the oral hygiene and periodontal status in the primitive tribe group of Bharias in Patalkot, Madhya Pradesh, India. MATERIALS AND METHODS: A descriptive cross-sectional study was undertaken with sample size of 462 patients. The sample was selected using simple random technique. A predefined pro forma was used to record information about oral hygiene practices and tobacco-related habits. Oral Hygiene Index-simplified (OHI-S), Community Periodontal Index (CPI), and loss of attachment (LOA) were used to assess oral hygiene and periodontal status, respectively. RESULTS: The prevalence of periodontal disease based on CPI scores showed that 35.4 % had periodontal pocket > 6mm. It was also found that 27.9% people had attachment loss of 6-8mm. Mean Debris Index-simplified, Calculus Index-simplified, and OHI-S for the participants were 1.59 ± 0.73, 0.99 ± 0.70, and 2.56 ± 1.36, respectively. Poor oral hygiene status was found in 36.3% of Bharias. CONCLUSION: Higher prevalence of periodontal diseases and poor oral hygiene status in Bharia people can be attributed mainly to their difficult terrain, isolation, very low literacy level, socioeconomic status, and cultural practices.
