To fabricate a proportional smile is an extremely challenging effort for an aesthetic dentist. This challenge becomes even more perplexing when it gets complicated by disease involving the periodontal and periapical zone. This case report highlights a satisfactorily acceptable management of a case in which a malaligned maxillary central incisor complicated with a resorptive defect was treated effectively through wellorganized team diagnosis and treatment planning, comprising of endodontic therapy, followed by periodontal regenerative treatment using bone graft and allograft barrier membranes to enhance its restorative ability. The final restoration was obtained by a fixed prosthesis using pink colored porcelain, which resolved the malalignment and esthetic concerns of the patient. This multidisciplinary approach provided patient benefit from the periodontal, restorative and prosthetic foundation that consistently produced optimal results for two years. [ABSTRACT FROM AUTHOR]

The aim of present invitro study was to investigate antimicrobial efficacy of leaf extract of the cashew plant (Anacardium occidentale) and 2% chlorhexidine gluconate solution against Enterococcus faecalis and Candida albicans. Disk diffusion method using lawn cultures of the E. faecalis and C. albicans was performed to determine the antimicrobial efficacy. The inoculums of these organisms were used to make the lawn culture on sabouraud's agar and blood agar plates. Wells were prepared in these lawn cultures and filled with the various concentrations of the test solutions. The agar plates were incubated at 37° C and zone of inhibition was examined after 48 hours. The results suggest that leaf extract of Anacardium occidentale had antibacterial activity against E. faecalis which was equivalent to Chlorhexidine. However, its antifungal activity against C. albicans was poor compared to Chlorhexidine [ABSTRACT FROM AUTHOR]

The aim of present in vitro study was to investigate antimicrobial efficacy of hydroalcoholic extract of Cymbopogon citratus and 2% chlorhexidine gluconate solution against Candida albicans and Enterococcus faecalis. Punch well method using lawn cultures of the C. albicans and E. faecalis was performed to determine the antimicrobial efficacy in the intial stage. The inoculae of these organisms were used to make the lawn culture on Muller Hinton agar plates. Wells were prepared in these lawn cultures and filled with the test agents. The agar plates were kept for incubation at 370 C and zone of inhibition was examined after 24 to 48 hours. Further, Direct Contact method was performed to establish the temporal relation between the pre determined concentration of the extract and the microbicidal efficacy. Gaussian test was employed as test of significance (p<0.05). The results suggest that there was a significant difference in the antimicrobial activity between C. citratus and chlorhexidine gluconate against C. albicans and E. faecalis. C. citratus had a significant antimicrobial efficacy against C. albicans than E. faecalis whereas, chlorhexidine gluconate was more effective against E. faecalis than C. albicans.

The scientific literature regarding dental application for laser is increasing. The past decade has seen a veritable explosion of research into the clinical applications of lasers in dental practice. Once regarded as a complex technology with limited uses in clinical dentistry, has grown with its awareness and usefulness in the armamentarium of the modern dental practice. They have been used as an adjunct or alternative to the traditional approaches. Since the development of the ruby laser by Maimam in 1960, a variety of papers on potential application of lasers in dentistry have been published. Various, and at times conflicting, claims by manufacturers, scientists and clinicians fill dental meetings and journals. The purpose of this paper is to review the general principles of lasers including their properties, components, tissue interaction, hazards and laser safety. With the potential availability of many new laser wave lengths and modes, much interest is developing in this promising field. [ABSTRACT FROM AUTHOR]

Aim: This study evaluated in vitro, the smear layer removing ability of different concentrations (3%, 5% or 7%) of maleic acid and a commonly used EDTA based paste preparation (RC-prep) both followed by irrigation with 2.5% NaOCl on instrumented root canal surface. Methods: Fifty extracted human maxillary anterior teeth were used. Crown portions of the teeth were decoronated and root canals were instrumented and irrigated with 3%, 5% or 7% maleic acid or RC- prep followed by 2.5% NaOCl. Following irrigation, middle and apical thirds of the root canal surface were examined under SEM for the presence or absence of smear layer. Scores were evaluated using the Wilcoxon matched pair signed rank test and analysis of comparison among the groups was calculated using Chi-square lest. Results: Results showed that all the three concentrations of maleic acid were better than EDTA (RC- prep) in removing the smear layer from both the middle and apical third of the root canal system. Conclusion: Maleic acid can be used as an alternative agent to EDTA in the removal of the smear layer from the root canal surface in endodontics. [ABSTRACT FROM AUTHOR]

Dental procedures, oral infections and poor oral hygiene can provoke the introduction of oral microorganisms into the blood stream or the lymphatic system. The subsequent attachment and multiplication of these bacteria on tissues or organs can lead to focal oral infections. Pathogenic agents also remain at their primary oral site but the toxins liberated can reach an organ or tissue via the bloodstream and cause injury. The present case report describes a rare case of Uveitis caused by a non vital tooth and its management. Clinical significance: An endodontists should be aware that, the odontogenic infections particularly a non vital tooth can also cause uveitis. [ABSTRACT FROM AUTHOR]
