The purpose of this review was to get significant experimental data about the acid etching technique upon pulpo-dentinal complex highlighting aspects such as pulpal biology and dentinal permeability. Studies since early 70's, going 80's 90's show value retention well need protective bases lower toxic effects etching.

this case report describes the treatment of two immature maxillary central incisors in a 7- year-old female patient. she suffered complicated crown fracture because of trauma, and the root formation was incomplete. white mineral trioxide aggregate (mta) was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. follow-up ev...

INTRODUCTION Microorganisms should be considered to have the major role in starting and perpetuation of pulpo-periapical diseases. Using intracanal medicaments is necessary to gain a bacteria-free environment in the canal system. Calcium hydroxide (abbreviated as Ca(OH)2), which is the most commonly used medicament in endodontic therapy, has been shown to be effective against primary sources of...

PURPOSE The aim of this article is to review a group of lesions associated with periodontal ligament (PDL) widening. MATERIALS AND METHODS An electronic search was performed using specialized databases such as Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus to find relevant studies by using keywords such as "periodontium", "periodontal ligament", "periodontal ligament space...

In all-ceramic restorations, crack formation and propagation phenomena are of major concern, since they may result in intra-oral fracture. The objective of this study was calculation of damage in porcelain MOD inlays by utilization of a finite-element (FE) implementation of the distributed crack theory. "Damage" is defined as the parameter that describes the local decrease of stiffness caused b...
