objective: loss of tooth structure due to dental caries and cavity preparation can reduce fracture resistance, especially in endodontically treated teeth. the aim of the present study was to evaluate fracture resistance of pulpotomized primary molar teeth restored with extensive multisurface amalgam restorations. materials and methods: eighty extracted carious human primary molar teeth were sel...

This study aimed to compare the push-out bond strength of a bulk-fill and conventional composite resin root dentin primary anterior teeth using 7th-generation bonding agent. in vitro evaluated 24 randomly divided into two groups: Filtek P60 resins. Single Bond Universal adhesive was used for bonding. After filling coronal part canal with resin, were mounted acrylic sliced obtain 1-mm-thick sect...

Objective: To investigate the types of restorative materials used for treatment in primary teeth through a retrospective university-based study. Material and Methods: The sample consisted all clinical records children attended at Pediatric Dentistry Clinic School Ribeirão Preto University São Paulo Brazil. Inclusion criteria were anterior posterior that received dental restorations caries lesio...

OBJECTIVE THE AIM WAS TO EVALUATE THE EFFECT OF ER, CR: YSGG laser and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on surface micro-hardness of primary tooth enamel. MATERIALS AND METHODS A total of 30 freshly extracted caries free primary anterior teeth were cleaned and stored in 1% thymol. Teeth were embedded in acrylic resin such that only their buccal surfaces were exposed...

The visibility of anterior teeth was studied in a population of 425 subjects. Scoring photographic data gave the percentages of anterior teeth that would not show a crown margin if it were placed in incisal, middle, or gingival sections. The results of this study indicate: their anterior teeth which would not show unless the lips were retracted.

A study was conducted to determine differences in pulpal sensitivity of the maxillary primary anterior teeth in groups of children with unilateral clefts of the lip, alveolar process and palate, bilateral clefts of the lip process, and children without clefts. Thirty-nine children between the ages of 4 and 5 years with a total of 216 maxillary primary anterior teeth were tested using a pulp tes...

The golden proportion is a well-known phenomenon and considered often cited as frequently occurring in nature. It has been demonstrated by various artists, mathematicians, scientists even philosophers. revolves around living beings inactive creatures; synthetic components designs seem to follow the proportion. Human are genetically developed so that they can easily recognize pleasurable because...

Sphagesaurus montealtensis is a sphagesaurid whose original description was based on a comparison with Sphagesaurus huenei, the only species of the clade described to that date. Better preparation of the holotype and the discovery of a new specimen have allowed the review of some characteristics and the identification of several synapomorphies of S. montealtensis with the genus Caipirasuchus: p...

The objective of this study was to analyze the correlation between lower anterior teeth crowding and the periodontal status among cadets of Armed Forces Institute of Dentistry. The investigation of this relationship was done on 60 cadets. 30 subjects each represented the experimental and the control sample, with an age range between 19-24 years. Plaque Index (PI) of lower six anterior teeth was...
