A study of complexity of oral mucosa using fractal geometry.

Background: The oral mucosa lining the oral cavity is composed of epithelium supported by connective tissue. The shape of the epithelial-connective tissue interface has traditionally been used to describe physiological and pathological changes in the oral mucosa.

Aim: The aim is to evaluate the morphometric complexity in normal, dysplastic, well-differentiated, and moderately differentiated squamous cell carcinoma (SCC) of the oral mucosa using fractal geometry.

Reorientation simplified: a device for recording and reproducing the path of insertion for removable partial dentures.

Aim: The record of path of insertion on the dental cast is part of the dentist's work authorization to the dental laboratory technician. The path of insertion record enables the dental technician to replace the cast on a surveyor in the same position that the dentist selected. Analysis of factors that influence the path of insertion should determine a path of insertion that will reduce the potential for dislodgement and promote stability of removable partial denture (RPD).

A rare root canal configuration of bilateral maxillary first molar with 7 root canals diagnosed using cone-beam computed tomographic scanning: a case report.

Introduction: The complexity of the root canal system of maxillary molars presents a constant challenge in the diagnosis and treatment of these teeth. This case report describes the importance of a surgical operating microscope and cone-beam computed tomographic (CBCT) imaging.

Methods: Root canal treatment of a left maxillary first molar with 3 roots and 7 canals was successfully performed.

Esthetic rehabilitation of discolored anterior teeth with porcelain veneers.

The common man is bombarded by the media extolling the virtues of "the perfect smile." In the 21(st) century of esthetic dentistry, fractured, malformed, malposed, and discolored teeth can be changed and restored to highly desirable form due to introduction of wide range of esthetic materials and techniques. Porcelain veneers is a conservative method of restoring the appearance of discolored, pitted teeth, and teeth with diastemas that provide extremely good esthetic results.

Congenital granular cell epulis of a newborn.

The congenital granular cell epulis (CGCE) is a rare tumor, which is apparent at birth. The histogenesis is still uncertain, but several theories, including origin from epithelial, undifferentiated mesenchymal cells, pericytes, fibroblasts, smooth muscle cells, and nerve-related cells have been proposed. This case report describes management of a 2-day-old baby girl having a large, round, soft, single 3 × 4 cm, pedunculated swelling, on the lower anterior ridge, which was causing difficulty in feeding.

Chemoprevention of premalignant and malignant lesions of oral cavity: Recent trends.

The word chemoprevention includes prevention of initiation, promotion, and progression of carcinogenesis to cancer. This article is an attempt to review the dietary chemopreventive agents and their mode of action in chemoprevention of oral premalignant lesions and oral cancer using a systematic approach. Selected chemoprevention trials are discussed with a focus on strategies of trial design and clinical outcome.

In vitro comparative evaluation of the effect of two different fiber reinforcements on the fracture toughness of provisional restorative resins.

Background: Fracture of provisional fixed partial denture (FPD) may jeopardize the success of provisional prosthodontic treatment phase and cause patient discomfort.
