Direct pulp capping has been used as an alternative approach to the maintenance of vital pulp so that many tooth extractions and root canal treatments could have been avoided through the conservative approach of direct pulp capping. For this purpose different kinds of materials used such as Zinc Oxide Eugenol, Glass Ionomer(GI), Resin Modified Glass Ionomer (RMGI), Adhesive systems, Calcium Hydroxide, Mineral Trioxide Aggregate (MTA) and Biodentine. The MTA clinically performed more effective than conventional Calcium Hydroxide liner as a direct pulp capping material, showed higher success rate than dycal. MTA easier to use clinically as a direct pulp capping material. MTA provided better long term results more effective than Calcium Hydroxide in maintaining long-term vitality. MAT significantly less toxic, less pulpal inflammations. MTA more predictable than dycal in formation of dentin barrier and superior than Calcium Hydroxide in dentinogenesis process in human pulp. MTA is more effective and superior comparing the Calcium Hydroxide as a direct pulp capping material, showed higher success rate with favorable outcomes in maintaining long term tooth vitality and easier to use in pulp capping. The MTA is less toxic, less pulpal inflammation capping compared to Calcium Hydroxide. MTA superior and in dentinogenic process and more predictable hard tissue barrier formation.","PeriodicalId":361768,"journal":{"name":"Online Journal of Dentistry & Oral Health","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121836738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifteen U.S. dental schools were selected, six of which used some type of pass/fail grading, the remainder used traditional grading and were randomly selected from a list of all U.S. dental schools. Six schools of the fifteen received the questionnaire which included demographic questions, questions on status as student or faculty, questions on current school grading system and individual preference for grading system types. Data was analyzed using an ANOVA with post hoc analysis using the Bonferroni method. Faculty significantly strongly disagree with pass/fail grading as compared to students (p=0.001, CI 3.07-3.70). Additionally dental school faculty were more likely to disagree with the pass/fail/pass with honors grading system than first and second year dental students (p=0.001, CI 2.74-3.38). Faculty agree significantly more with traditional grading compared to students. (p=0.001, CI 2.10-2.77). Overall faculty prefer traditional grading and disagree with pass/fail grading of both types especially compared to first and second year students concerning pass/fail/pass with honors grading. This study will add to a growing body of research on the benefits, risks and effects of varying types of grading systems used in dental schools and their relation to the potential success of students both in dental education and those entering into dental postgraduate education programs.","PeriodicalId":361768,"journal":{"name":"Online Journal of Dentistry & Oral Health","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115442432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study design: A total of 261; 19-55 year old mothers were selected. Clinical examination of mothers were conducted to estimate dental caries experience with the Silness-Loe index, as well as stimulated saliva were collected to assess S.mutans levels by colony forming units (CFU). Difference in proportions calculated the differences between the groups and the associated OR of colonization with tested factors were estimated and significancy was determine by chi square and P value. Results: Out of 261 mothers, 72 (27.6%) showed heavy colonization of S.mutans. Overall 12 (4.6%) mothers were caries free (Score 0) and 249 (95.4%) presented with caries (Score 1-3). There was significant grow in the rate of S.mutans heavy colonization with growing caries score (score 1=20.8%, 32.2% for score2 and 46.2% for score 3). There was ascend in the rate of S.mutans heavy colonization with growing age. Regarding oral hygiene practices, there was significant grow in the rate of S.mutans heavy colonization with using mouthwashes while significant drop in the rate with using flossing and regular visit of dentist. Conclusion: A high rate of heavy colonization of S.mutans occurred, with significant grow in the rate with growing caries score, there is negative effect of using regular mouthwashes while positive one with using flossing and regular visit of dentist.","PeriodicalId":361768,"journal":{"name":"Online Journal of Dentistry & Oral Health","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125734888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study carried out for one year, starting in December 2011 and ending in November 2012. The study included 296 patients of whom 153 were males and 143 were females, their ages ranged from 5 to 65 years old, with a mean age of 36.2 years. Clinical and demographic data were collected in standard questionnaire then oral swabs or pus were collected from patients and cultured, isolated and identified using standard laboratory techniques. The prevalence of different clinical oral infections were 20.6% for dental abscesses, 19.3% for periodontal abscesses, 17.6% for gingivitis, 16.6% for periodentitis, 10.1% for dental caries, 8.4% for pulpitis and 7.4% for oral thrush. Out of the total 296 cultured swabs, only 217 swabs yielded positive culture with a percentage of 73.3%. Gram-Positive bacteria constituted 67.4% of the total isolates, where Staph. aureus was the predominant pathogen (43.1%), whereas, the Gram-Negative bacteria represented only 26.6% of the total isolates, in which Bacteroides spp was the predominant Gram-Negative isolate (26.6%), and finally Candida albicans constituted only 6% of the total micro-organisms. It can be concluded from this that the prevalence of dental abscesses in oral infections was more common, Staph. aureus was the most common bacterial isolate and Bacteroides spp was positive in more than quarter of the total isolated microorganisms and Strept. mutans occurred in high frequency in dental caries patients.","PeriodicalId":361768,"journal":{"name":"Online Journal of Dentistry & Oral Health","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134601555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
