Clinical utility of locally-delivered collagen-based biodegradable tetracycline fibers in periodontal therapy: an in vivo study.

Aim: The purpose of the present investigation was to evaluate and compare the efficacy of resorbable collagen-based tetracycline fibers (Periodontal Plus AB fibers) given as an adjunct to scaling and root planing, with the clinical effects of scaling and root planning delivered as a monotherapy, in the treatment of chronic periodontitis.

Methods: A split-mouth design was used to conduct this study. Forty patients with periodontal pockets ranging from ≥ 5 mm to ≤ 7 mm, with minimum of two sites in two non-adjacent quadrants, were selected for the study.

Papillon-Lefevre syndrome (PLS) without cathepsin C mutation: A rare early onset partially penetrant variant of PLS.

Papillon-Lefevre syndrome (PLS) is a very rare, autosomal recessive syndrome characterized by palmar-plantar hyperkeratosis and severe destructive periodontitis. Most patients present with PLS harbor mutations in the cathepsin C gene, but recent studies have identified individuals with classic PLS symptoms without such mutations. This suggests more genetic heterogeneity for PLS than previously thought.

Aesthetic replacement of an anterior tooth using the natural tooth as a pontic; an innovative technique.

This article presents a novel technique for replacing an anterior tooth. A new modification to the clinical technique of direct fabrication of a resin-bonded bridge was employed, in which the patient's natural tooth was used as a pontic. Treatment with this modification led to overall improved aesthetics and reduced treatment cost.

Multicentric peripheral ossifying fibroma: A case report and review of the literature.

A peripheral cement-ossifying fibroma is a benign fibro-osseous lesion of a reactive rather than a neoplastic nature, whose pathogenesis is uncertain. It predominantly affects adolescents and young adults, with the peak prevalence between 10 and 19 years, especially affecting females (two to four times more). Such lesions are commonly found on the maxillary bone.

Spiral computed tomographic evaluation and endodontic management of a mandibular second molar with four roots. A case report and literature review.

The vast majority of mandibular second molars have two roots with three root canals; however, variations in molar root canal anatomy are not uncommon. To the best of our knowledge, four rooted mandibular second molar with three mesial roots and one distal root has never been reported. Herein, we present the endodontic management of a four rooted mandibular second molar tooth, diagnosed with the assistance of spiral computed tomography (SCT) with a brief review of literature.

The dissolving ability of different organic solvents on three different root canal sealers: in vitro study.

Introduction: The purpose of this in vitro study was to evaluate three common gutta-percha solvents' effectiveness in dissolving three different types of root canal sealers.

Materials And Methods: The solubility of three different root canal sealers (AH Plus, Apexit Plus and Endoflas FS) was assessed in xylene, refined orange oil, tetrachloroethylene and distilled water (control). One-hundred twenty samples of root canal sealers were prepared and then divided into three equal groups (n=40).

Papillon-Lefèvre syndrome: Case report and review of the literature.

Papillon-Lefèvre syndrome is a very rare syndrome of autosomal recessive inheritance characterized by palmar-plantar hyperkeratosis and early onset of a severe destructive periodontitis leading to premature loss of both primary and permanent dentitions. Various etiopathogenic factors are associated with the syndrome; but a recent report has suggested that the condition is linked to mutations of the cathepsin C gene. Two cases of Papillon-Lefèvre syndrome in the same family, having all of the characteristic features are presented.

Dissolving efficacy of different organic solvents on gutta-percha and resilon root canal obturating materials at different immersion time intervals.

Unlabelled: BACKGROUND AIM: The purpose of this study was to compare and evaluate the dissolving capability of various endodontic solvents used during endodontic retreatment on resilon and gutta-percha at different immersion time intervals.

Materials And Methods: 160 ISO no. 40 cones (0.

Spiral computed tomographic evaluation and endodontic management of a mandibular first molar with three distal canals.

The use of spiral computed tomography serves as a boon in endodontic diagnosis of complex anatomic variations. The present case demonstrates the spiral tomographic evaluation and endodontic management of a mandibular first molar with 5 canals (2 mesial and 3 distal canals), which is a very rare anatomic variant. Such anatomic variations should be taken into account in day to day endodontic practice to ensure a high degree of clinical success.
