ABSTRACT
Background: Dental caries is one of the most common concerns in oral health of children. Arresting these lesions is a treatment which is gaining momentum as against conventional restorative approaches. Aim: The aim is to evaluate the efficacy of nanosilver fluoride (NSF) as a caries arresting agent in primary teeth or first permanent molars in children. Design: The protocol for the systematic review has been registered with PROSPERO database (CRD42020162386). Several databases, such as PubMed®/MEDLINE, Web of Science™, Scopus®, Google Scholar, LILACS, Cochrane Library, ProQuest, and BBO, were searched for randomized controlled trials (RCTs) which evaluated the arrestment of caries, in primary teeth and first permanent molars in children, with a minimum follow-up of 6 months. The Risk of Bias tool by Cochrane reviews system software, Revman 5.4.1, was used for quality assessment of the included RCTs. The quality evaluation was done using the GRADE approach. Heterogeneity was assessed using Cochrane's Q and I2 statistics. Results: Five studies were included for qualitative and quantitative analysis. The Risk Ratio for NSF versus active control group was assessed to be 1.09 (0.93-1.28) with 95% Confidence Interval and for placebo control was 0.49 (0.35-0.67). Conclusion: NSF shows promise as a caries arrestment agent when applied in primary teeth.
ABSTRACT
Introduction: The third molar (3M) varies more than other molars in terms of shape, size, timing of eruption, and tendencytoward impaction. Hence, studies need to be carried out to clarify the association of the various patterns of facial growth withmandibular 3M impaction.Purpose: The purpose of this study is to relate the level of impaction of mandibular 3Ms and their inclinations to various patternsof facial growth among Indian patients.Materials and Methods: A total of 207 lateral cephalograms and optic pathway gliomas (OPGs) of patients were obtainedfrom NISSAN Radiological and Diagnostic Centre. The OPGs were analyzed by a single examiner as per: (1) Angulations(using Quek’s analysis - beta angle, 2003). (2) Depth of 3Ms. The lateral cephalograms were assessed by a single examinerusing: (1) Down’s analysis. (2) Beta angle. (3)Jarabak’s ratio. (4) Bjork’s analysis.The subjects were further classified into skeletal Class I, II, and III as well as into horizontal, vertical, and normal growth patterns.The final study data were subjected to a Pearson correlation test to check the association between the 3M impactions andvarious angles. The values found significant were coded into ordinate data and Kendall’s Tau-B Test was done.Results: Statistically, significant correlation was found between depth of impacted mandibular 3Ms and facial angle, Y-axis,cant of occlusion, angle of convexity, and gonial angle.Conclusion: Greater incidence of 3Ms was found to be at position B and C in Class II patients as compared to Class I and IIIpatients. Furthermore, patients showing vertical growth pattern were found to have increased percentage of mandibular 3Mimpactions.
ABSTRACT
Implant therapy has become an important part of treatment to restore function and esthetics in partially/completely edentulous patients. Inspite of the progress made in implant dentistry since its inception, there have been some loopholes in scientific based knowledge and established clinical experience amongst dental professionals and postgraduates.So,an analysis was performed of the real picture. Objectives: A study was conducted to assess and compare the knowledge, attitude and practice of dental implants among dental postgraduate students and dental practitioners (General and institutional)in Davangere City, Karnataka and to identify the variations in their knowledge, attitude and practice with respect to dentist's factors (years of experience, implant training and their specialization). Materials and Methods: A cross sectional questionnaire based survey was conducted using census approach with informed consent. A pretested, self administered questionnaire containing demographic details and knowledge ,attitude and practice based questions was distributed and collected back from the respondents. Responses were coded before and decoded after the analysis. Statistical analysis was performed using SPSS SoftwareV17.0. Results: The results were determined after the statistically analyzed and concluded that the knowledge was widespread among postgraduates and dental practitioners and variations existed amongst the subjects with respect to age, gender, years of experience, practice type, implant training and their specialization. It was also found that the attitude and practice towards implants and their evidence based knowledge about the same was variable.
