An analysis of the palatal surface anatomy of maxillary central incisors: complexity behind the simplicity.

Background: The palatal surface of the maxillary anterior teeth in conjunction with the incisal edge represents the mechanical area, which is of great importance for lateral and anterior guidance. Therefore, in terms of restorative dentistry, it is crucial for the clinician to have a detailed knowledge of the palatal surface anatomy (PSA) of the different maxillary anterior teeth in order to reestablish a definitive correlation between form, function, and esthetics. The aim of the present study was to analyze the variations in the PSA of the maxillary central incisors (CIs) and their correlation with tooth form and gender.

Biological posts and crown: An esthetic recovery of smile.

Anterior teeth fracture is a common form of dental trauma that mainly affects children and adolescents. Maxillary incisors are the most commonly affected teeth. Loss of coronal tooth structure might affect esthetics and function.

Randomized controlled clinical trial on the efficacy of dentin desensitizing agents.

Objective: To investigate the effects of four dentin desensitizers on pain reduction in hypersensitive cervical dentin lesions.

Materials And Methods: The trial was designed as a randomized, controlled, four-arm, single-masked study. Fifty subjects with at least one hypersensitive lesion in each of the four quadrants were allocated.
