RESUMO
UNLABELLED: Aims & Objective: To assess the oral health awareness and periodontal health status of different socio-economic groups in out-patient department of the Teerthanker Mahaveer Dental College and Research Centre (TMDC&RC), Moradabad, India. MATERIALS AND METHODS: This cross-sectional study was conducted on 416 subjects of 30-60 years age group with different socio-economic status classified according to modified Kuppuswamy scale (2012). Subjects were interviewed by the questionnaire and Community Periodontal Index was recorded. STATISTICAL ANALYSIS: Chi-square test (SPSS version 17). RESULT: This study showed that the code 2 and code 3 is more in lower socio-economic status (p =0.115 and p=0.079 respectively). Significant association was seen in Code 0, code 1 & code 4 (p<0.01) which is indicative that upper class have more healthy periodontal status than lower. CONCLUSION: Significant association exists between oral health awareness and periodontal health with the socio-economic status of the individual.
RESUMO
CONTEXT: The success of endodontic treatment therapy depends on how well we eliminate pathogenic microflora from the root canal system as micro organism as the major cause of root canal infection. Conventional root canal treatment can fail if microorganisms cannot be removed sufficiently by thorough cleaning, shaping of root canal. Newer modalities such as photodynamic therapy are being tried now a days for disinfection of root canals. Aim & Objectives: The basic aim of this study was assessment of the antimicrobial efficacy of Photodynamic Therapy in deeper dentinal tubules for effective disinfection of root canals using microbiological and scanning electron microscopic examination in vitro. MATERIALS AND METHODS: The study was conducted at Teerthanker Mahaveer Dental College & Research Centre. The teeth required for study was collected from Department of Oral and Maxillofacial Surgery. Only freshly extracted 20 intact, non carious single rooted teeth which were indicated for orthodontic treatment were taken for this study. Statistical analysis was done using Student's Unpaired t-test were at (p<0.001) was found to be highly significant. Microbiological examination of samples were done and colony forming units were counted to assess the disinfection potential of photodynamic therapy. Scanning electron microscopic examination of samples was done to check penetration of bacteria's into deeper dentinal tubules. RESULTS: On examination, there was a marked reduction in microbial growth after use of photodynamic therapy. On scanning electron microscopic examination, it was observed that there were less number of bacteria's in deeper dentinal tubules in case of PDT group as compared to control group. CONCLUSION: The results of the present study indicate that PDT can be effectively used during antimicrobial procedures along with conventional disinfection procedure for sterilization of root canals.
