Non-surgical Management Of A Large Periapical Lesion: A Case Report

Aim - To report the non-surgical management of a large periapical lesion. This paper presents the successful management of periapical lesion with successful resolution of signs and symptoms both clinically and radiographically. With dawn of era of minimal intervention in dentistry, surgical management of periapical lesions become controversial. Nonsurgical or conservative management of periapical lesions not only cause less trauma to the tissues, but also promote faster and less eventful healing. This article highlights the healing potential of non surgical endodontic treatment in the management of large periapical lesions.

Color and its Dimensions - A Review.

In the modern civilized, cosmetically conscious world, well-contoured and well-aligned white teeth set the standard for beauty. Such teeth are not only considered attractive, but are also indicative of nutritional health, self-esteem and hygienic pride. Attention to accuracy and reliability of any spectral or color measurement system, with further attention to the proper statistical parameters to evaluate accuracy and reliability.

Effect of Morinda Citrifolia Juice and Triphala as Root Canal Irrigants on Sealer Penetration Depth Into the Dentinal Tubules. – A Confocal Laser Microscope Study.

Aim: The aim of this study was to evaluate the effect of Morinda citrifolia juice (MCJ) and Triphala on sealer penetration depth into the dentinal tubules as root canal irrigants. Materials and Methods: Forty five single rooted extracted human teeth were collected; decoronated and root canal length were standardized to16mm. Cleaning and shaping was done with protaper universal rotary instruments till F5. 30 samples were selected randomly and divided into two groups with 15 samples in each, according to the final irrigation regimen. In Group I, 5 ml of MCJ was used for 1min and in Group II; 5 ml of Triphala was used. The remaining 15 samples were irrigated with 5ml of Smear clear which acted as a positive control Group. Obturation was done with corresponding gutta-percha points and AH 26 sealer (Dentsply; DeTrey, Konstanz, Germany) labelled with fluorescent dye and left to set for 48 hrs. Then, the roots were sectioned and subjected to confocal laser microscope. Results: Statistical analysis was done by two-way analysis of variance (ANOVA) and Tukey multiple post-hoc procedures. The sealer penetration depth is higher in the MCJ group than the Triphala group at all three levels. Conclusion: MCJ showed a significant sealer penetration depth than Triphala.

A Review of In Vitro Evaluation of Shaping Ability Assessment Techniques-An Evolution from Past to Present.

The ideal preparation for a root canal is a continuously tapered funnel shape with the smallest diameter at the apex and the widest diameter at the canal orifice. The main parameters used to evaluate a technique or an instrument which has been developed for root canal preparation should be ‘shaping the root canal whilst protecting the curvature of the canal’. Various methods have been proposed for evaluation of shaping ability of instruments. A reliable standardization and proper methodology is necessary for proper positioning of samples for obtaining images before and after root canal preparation. All techniques have their own benefits and limitations.

Methods for Quantifying Sealing Ability of Endodontic Sealers-A Review.

The current concept among clinicians is that after complete debridement, a three-dimensional obturation of the root canal space that is free of inflammation constitutes the key factor for successful endodontic therapy. Different sealer formulations have been subjected to extensive research with respect to their mechanical and biological properties, reflecting the prevailing belief that the appropriate selection of a sealer and its clinical performance may influence, at least in part, the outcome of endodontic therapy. Many techniques have been suggested and evaluated, most of them advocating the use of gutta-percha as the core material and with sealer of a different composition to fill the residual gaps between the individual gutta-percha points and between the gutta-percha and the canal wall. Evaluating the sealing competency of the sealers to the root canal walls is utmost consequential for the presage of outcome of treatment.

Evaluation of Effect of Allium Sativum On Smear Layer Removal In Root Canals - An Ex Vivo Study.

Background: Allium sativum was known to possess antibacterial activity because of the presence of allic acid in its bulbs. Aim: To compare and evaluate the smear layer removal capacity of 3% NaOCl, 2% Allium sativum, 17% EDTA and saline. Methodology: Forty one extracted teeth were collected and the root canals were instrumented with protaper till F3 size. During root canal preparation, irrigations were made with the different solutions being evaluated and the roots were cut in the buccolingual direction for SEM analysis, to ascertain the presence or absence of smear layer and debris. Statistical analysis: Pearson’s chi-square test and fisher exact test were used. Results: In the coronal and middle thirds, Group I produced a synergistic effect, resulting in effective removal of the entire smear layer. Group II has good smear layer removal also. Conclusion: Allium sativum does have an effect on the removal of smear layer when used as endodontic irrigant.
