Effectiveness of 2% Articaine as an anesthetic agent in children: randomized controlled trial.

Abstract: The aim of this study was to compare the effectiveness of 2% articaine and 2% lignocaine in achieving adequate anesthesia in children between the age group of 6–13 years using inferior alveolar nerve block. A triple blinded randomized controlled trial was conducted in 180 participants (90 patients- 2% articaine, 90 patients-2% lignocaine). Effectiveness of the anesthetic agent was determined at 3 points determined by subjective evaluation of pain using pain scales (FPS-R). Paired sample t-test and chi square test were performed for statistical significance. Anesthetic success for 2% articaine were 64.4%, 42.2% and 81.8% respectively. The anesthetic success of 2% lignocaine was 66.7%, 48.9% and 85.7% at point one, point two and point three respectively (p > 0.05). This study concludes that 2% articaine in 1:2,00,000 did not demonstrate superior clinical effectiveness in comparison to 2% lignocaine. Lignocaine has always been considered the gold standard. With its unique chemical structure and increased potency, Articaine has been gaining popularity. Its efficacy in 2% concentration had not been compared to 2% lignocaine. 2% articaine did not show clinical superiority but its comparable effectiveness with lignocaine can encourage further research in using articaine in reduced concentrations to improve effectiveness.

Factors determining post selection: a literature review

Abstract: Most endodontically treated teeth require a post-and-core build-up for restoring the teeth to optimum health and function. Selection of an appropriate post-and-core system from the wide variety of those available may be a clinical dilemma. Therefore, the purpose of this article is to review the literature to identify the various factors that influence the selection of the post-and-core assembly. English-language peer-reviewed articles between 1961 and 2002 were identified using MEDLINE, as well as a hand search. The following key words were used: post, design, retention, fracture resistance, survivability, and esthetics. Selection of a post and core system should satisfy many interrelated biologic, mechanical, and esthetic factors to optimally restore the endodontically treated tooth to adequate form and function. This review may serve as a guide to aid the clinician in the selection of a post-and-core system.

Factors affecting the fracture resistance of post-core reconstructed teeth: a review.

Abstract: Purpose This article presents a review of the literature on factors that affect the resistance to fracture of post-core reconstructed teeth. Materials and methods Articles cited in a MEDLINE search were obtained from the journals and reviewed with respect to factors affecting fracture resistance of post-core reconstructed teeth. Results A large part of the literature reviewed emphasizes the stress distribution during insertion of posts and during function. Other factors, like post length, post diameter, amount of remaining dentin, post material, post adaptability, post design, cement, core material, core and crown design, biocompatibility of post material, use of treated tooth, and load experienced by restored tooth, are also found to influence the fracture resistance of a reconstructed tooth. Of all the factors enumerated, crown design, occlusal forces, and use of the treated tooth are found to have direct impact on the longevity of the restored tooth. Conclusion Literature indicates that (1) preservation of tooth structure is a must; (2) posts should not be used with the intention of reinforcing the tooth; (3) review of functional and parafunctional forces must be undertaken before restoring the tooth, as these will influence the prognosis; and (4) controlled prospective clinical studies evaluating each factor should be undertaken.

Zirconia-based fixed partial dentures: a clinical review.

Abstract: Ceramics have a long history in fixed prosthodontics of achieving optimal esthetics. Yttrium tetragonal zirconia polycrystal (Y-TZP)-based systems are a recent addition to the high-strength, all-ceramic systems used for crowns and fixed partial dentures. CAD/CAM-produced, Y-TZP-based systems are in considerable demand in esthetic and stress-bearing regions. The highly esthetic nature of zirconia coupled with its superior physical properties and biocompatibility have resulted in restorative systems that meet the demands of today's patients. Undoubtedly, these systems are considered to be prospective replacements for metal-ceramic restorations. This article reviews relevant contemporary literature regarding all-ceramic materials and systems and discusses their material properties, biocompatibility, advances in cementation, and more with special emphasis on clinical survival. The article also aims to provide recommendations for their use.

Types of Implant Surgical Guides in Dentistry: A Review

Abstract: Various techniques have been proposed for the fabrication of surgical guide templates in implant dentistry. The objective of this paper is to review the associated literature and recent advancements in this field, based on design concept. An electronic and hand search of the literature revealed 3 categories, namely, nonlimiting, partially limiting, and completely limiting design. Most clinicians still adopt the partially limiting design due to its cost-effectiveness and credibility. Moreover, clinicians use cross-sectional imaging during the preimplant assessment of surgical sites.
