Evaluation of facial asymmetry using digital photographs with computer aided analysis.

Facial asymmetries exist in all individuals. Due to these facial asymmetries that exist, a standardized approach in locating the occlusal plane that is parallel to the ala-tragus and interpupillary lines, may result in less than ideal esthetics in the final restoration. The challenge for the prosthodontist is to determine an acceptable occlusal plane with an individualized approach that can be used as a guide for alignment of the maxillary anterior teeth in cases that require their replacement or extensive restoration.

Noise levels in a dental teaching institute - A matter of concern!

Objective: To measure and assess the noise levels produced by various dental equipments in different areas of a dental institution and to recommend improvements if noise levels are not within permissible limits.

Material And Methods: Sound levels were measured at three different areas of a dental institution where learning and teaching activities are organized. The sound level was measured using a sound level meter known as 'decibulolmeter'.

Strength characteristics and marginal sealing ability of chlorhexidine-modified glass ionomer cement: an in vitro study.

Background: This study was done to compare and evaluate the compressive strength, diametral tensile strength, and microleakage of glass ionomer cement and chlorhexidine-modified glass ionomer cement. The glass ionomer cements used in the study were Fuji IX for group I and chlorhexidine-modified glass ionomer cement for group II.

Materials And Methods: The strength characteristics (compressive and diametral tensile strengths) and microleakage of both the groups were evaluated after 24 h.

Oral leiomyoma.

Oral leiomyoma is a benign smooth muscle tumor with a low incidence. Oral leiomyomas present as slow growing, asymptomatic sub mucosal masses, usually in the tongue, hard palate or buccal mucosa. They may be seen at any age and are usually discovered when they are 1 to 2 cm in diameter.

Dexmedetomidine and fentanyl combination for procedural sedation in a case of Duchenne muscular dystrophy.

Duchenne muscular dystrophy, an X-linked disorder characterized by progressive muscle weakness, is the most common muscular dystrophy among children leading to death before the end of third decade. Anesthesia in such patients pose a great challenge due to various complications associated with it. The dreaded metabolic and clinical complications occur due to various inhalational anesthetics and succinylcholine in this subset of patients.

Monomer systems for dental composites and their future: a review.

This review discusses the history of monomers used in resin composites, highlights recent and ongoing research reported in the field of dental monomer systems, and future development. The main deficiencies of current resin composites are polymerization shrinkage and insufficient wear resistance under high masticatory forces. The problem has been approached with the synthesis of potentially low-shrinking/nonshrinking resin composites.

The effect of occlusal restoration and loading on the development of abfraction lesions: A finite element study.

Background: Abfraction, a type of non-carious cervical tooth loss, is a poorly understood condition. One factor thought to contribute to the development of these lesions is the effect of occlusal loading and the presence of occlusal restoration.

Aim And Objectives: The aim of this paper is to study the stress profile in the cervical region of mandibular first premolar with variation of occlusal loads, and to compare the stress profile between sound and occlusally restored tooth under variation of occlusal load, using two-dimensional plane strain finite element model.
