ABSTRACT
Introduction: Dental aesthetic plays an important role inoverall facial representation of a person. A smile enhancesexpression of a person. A perfect harmony of size, form, andposition of the teeth and their relation with alveolar boneand gingival tissue have important role in creating a pleasingsmile. Excessive gingival melanin pigmentation can givebrownish to blackish colour to gingival.Case report: This case report highlights a case ofhyperpigmentation gingiva with midline diastema which wastreated by gingival depigmentation using the scalpel techniquewith frenectomy and cosmetic filling.Conclusion: The appearance of ‘black gum’ especially inhigh smile line person gives unaesthetic smile. The demandfor cosmetic therapy is commonly in people with pigmentedgingiva.
ABSTRACT
Aims: The objective of this in vitro study was to find out the efficacy of Novamin in remineralizing enamel surface on which artificial caries lesion had been created. The changes were analyzed using Vickers Hardness Testing Machine and Scanning electron microscope (SEM). Settings and Design: A total of 40 primary teeth were selected and divided into two groups: Control group and SHY NM (Novamin). All the samples were subjected to ph cycle protocol and assessed using Vickers Hardness Testing Machine and Scanning electron microscope. Each demineralized sample was randomly divided into two groups: Gp I –Control group, Gp II – Novamin (SHY NM). After 10-day period of ph cycle, the obtained data was analyzed statistically. Statistical Analysis Used: Pre and post groups were compared by paired t test. The significance of mean difference between the groups was done by Tukey's post hoc test after ascertaining normality by Shapiro-Wilk (W) test and homogeneity of variance by Levene's test. A two-tailed P value less than 0.05 (P < 0.05) was considered statistically significant. All analyses were performed on SPSS software (Windows version 17.0). Results: Statistical analysis showed that bioactive glass (novamin) remineralizes artificially induced carious lesion in primary teeth. Conclusions: SHY NM (Novamin) exhibited superior remineralization potential.
ABSTRACT
Introduction: Recent surveys reported that dentists inseveral countries have restricted knowledge about prescribingantibiotics. The aim of this study was to investigate theknowledge and attitude of a group of dentists in Jharkhandtowards antibiotic prescription.Material and Methods: The present study was conductedamongst a group of dentists in Jharkhand, a state in easternpart of India. A questionnaire was mailed to 150 dentists outof which 131 responded back. The questionnaire includedquestions about the knowledge and attitudes of dentists towardprescribing antibiotics to dental patients.Results: Amoxicillin and amoxicillin clauvanic acid were themost popular antibiotics. More than 66% of the sample prescribed antibiotics daily.Conclusion: There is a need to improve awareness of dentistsregarding antibiotic prescribing to patients particularly in theaspects of type of antibiotic and its clinical indications.
