Background: Chronic periodontitis is the most prevalent form of periodontitis with a multifactorial etiology, dental plaque being the primary etiologic agent. The removal of such etiologic factor through scaling and root planing builds the foundation of treatment. In addition, the use of an antimicrobial adjunct augments elimination of microbes leading to subsequent control of the disease. Chlorhexidine and Metronidazole have been found to be active against several periodontopathogens. In this study, the use of these antimicrobial gels has been made. To evaluate and compare the clinical efficacy of subgingival application of 1% Metronidazole, 1% Chlorhexidine and Combination gel when used as an adjunct to non-surgical therapy. Methods: A total of 120 patients, age group 30-60 years with chronic generalized periodontitis were included in the randomized, controlled, double blinded study. The patients were randomly divided into four groups and treated with scaling and root planing along with antimicrobial adjunct. The antimicrobials used were Chlorhexidine, Metronidazole, Combination of Chlorhexidine and Metronidazole, and Placebo. Clinical parameters (plaque index, gingival index, probing pocket depth and clinical attachment level) were recorded at baseline, 1 month and 3 months. Results: In all the groups, there was a statistically significant reduction in all the clinical parameters at different time intervals. Inter-group comparison with respect to clinical changes showed that Combination gel was the best. Conclusions: Long term, controlled randomized trials with more samples are suggested to further validate the efficacy of these antimicrobial drugs.
Corticotomy assisted orthodontic treatment is a promising interdisciplinary approach, which has offered solution to many limitations in the orthodontic therapy. The procedure involves the alveolar decortication in the form of cortical grooves and perforations performed around the teeth that are to be moved. In this case report, a 17 year old male under fixed orthodontic therapy with a complaint of delayed protraction of mandibular second molars underwent corticotomy procedure. The decortication was done followed by elevation of buccal and lingual flaps. After 2 weeks of the surgical procedure, orthodontic tooth movement was initiated.
Gingival augmentation technique is used to increase the thickness of attached gingiva and arresting the progress of recession. Autogenous epithelialised free gingival graft obtained from palate is a well-established periodontal plastic procedure for root coverage and increasing the width of attached gingiva. This case report shows augmentation of attached gingiva from operculum of erupting third molar as an alternative donor site in marginal tissue recession not extending beyond the mucogingival junction with soft and hard tissue loss interdentally of 31 and 41 in a 20-year-old female.
Ameloblastoma is an uncommon benign epithelial neoplasm of odontogenic origin that accounts for about 18% of the odontogenic tumour. It is a slow-growing, locally invasive but rarely metastatic tumour. Extraosseously occurring peripheral ameloblastoma is a rare variant that comprises about 2-10% of all ameloblastoma. We report a case of peripheral ameloblastoma in a 43-years old male patient affecting the mandibular canine-premolar region with a histopathological diagnosis of acanthomatous ameloblastoma. This case report emphasises the clinical, radiographic, and histological features of a rare variant that distinguishes it from the other similar appearing lesion on gingiva along with its various treatment modalities.
Background: In academic institutes, dental students are not only involved in academic activities, but also in the management of patients’ care. This calls for inculcation of adequate knowledge and positive attitude among them so that a good clinical practice is implemented in the dental setting, thereby creating a safe working environment for students as well as patients. Thus, the study was conducted to assess knowledge and attitude regarding infection control among undergraduate dental students of B.P.Koirala Institute of Health Sciences, Dharan, Nepal.Methods: An online descriptive cross-sectional study was conducted at BPKIHS from February till March 2021. Undergraduate students from third year, fourth year and internship were included in the study. A self-administered questionnaire comprised of demographic characteristics, knowledge and attitude regarding infection control was used to collect the data via a Google form. Descriptive and inferential statistics was used to analyze the data. The p value <0.05 was considered statistically significant at 95% confidence interval.Results: A total of 136 undergraduate dental students participated out of which 65.0% were females and 35.0% were males. Out of the total participants, 78.7% were found to have adequate knowledge while 74.3% participants showed ‘positive’ attitude. Mean age of the participants with adequate knowledge was significantly higher than participants with inadequate knowledge (p=0.047). The difference in knowledge among participants was statistically significant (p=0.001) in academic years. The majority (90.4%) of interns showed adequate knowledge followed by fourth year (83.7%) and third year (58.7%) students. The difference in attitude, was also statistically significant (p= 0.011) in academic years, but it was mostly (90.4%) of positive attitude in fourth year participants followed by third year (68.3%) and Interns (65.4 %).Conclusion: The present study reports adequate knowledge and positive attitude regarding infection control among undergraduate dental students in BPKIHS. Further studies are encouraged to be conducted among students from different academic institutes all over the country to ascertain their level of attitude and knowledge regarding infection control in dental care services.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
