OBJECTIVES Controversy exists regarding cavity preparation for restoration of interproximal caries in posterior teeth in terms of preserving the tooth structure and suitable stress distribution. This study aimed to assess the effect of extension and type of class II cavities and the remaining tooth structure in maxillary premolars restored with composite resin on the biomechanical properties of...

The effect of chewable saliva-stimulants on Streptococcus mutans levels in dental plaque and paraffin-stimulated whole saliva among participants who were mentally disabled was investigated. Over 64-days, 98 participants chewed one of four saliva-stimulating tablets five times/day. The tablets contained one of the following: xylitol (X) or sorbitol (S), or 1:1 mixtures of xylitol and erythritol ...

statement of problem: digital measurement of rvg may improve diagnostic interpretation of radiographs in terms of accuracy, although it has been shown that validity of linear measurements of interproximal bone loss could not be improved by basic digital manipulations. purpose: the aim of this study was to evaluate the accuracy of radiovisiography (rvg) in the linear measurement of interproximal...

The purpose of this study was to determine the need for supplemental periapical radiographs in planning restorative services and pulp treatment for primary molars when a child’s bite-wing radiographs were taken with No. Oor No. 2-size film. Forty-eight good quality bite-wing radiographs were selected from patients 5-7 years of age and sorted into four groups containing 12 films classified accor...

The best way to adjust proximal contacts of newly fabricated indirect restorations has been a long-standing unresolved issue in dentistry. Excessively tight contacts cause incomplete seating of indirect restorations and intrusion of adjacent teeth, which leads to patient discomfort, hypersensitivity, and recurrent dental caries at the crown margins. When seating indirect restorations, interprox...

The aim of the investigation was to compare overall and anterior Bolton ratios in different malocclusion groups with Bolton's standards. The material comprised 600 pre-treatment study casts (262 males and 338 females, aged 12-25 years), selected from the models of 3088 patients who had applied for orthodontic treatment based on the following criteria: permanent dentition from the first right mo...

One of the basic principles of orthodontics is the creation of space to facilitate tooth movement. With appropriate case selection, slenderization offers the ability to safely obtain sufficient space for tooth movement without the need for extractions and without compromising slenderized teeth. Introduction Creating space to facilitate tooth movement is one of the basic principles of orthodonti...

BACKGROUND Purified recombinant human platelet-derived growth factor BB (rhPDGF-BB) is a potent wound healing growth factor and stimulator of the proliferation and recruitment of both periodontal ligament (PDL) and bone cells. The hypothesis tested in this study was that application of rhPDGF-BB incorporated in bone allograft would induce regeneration of a complete new attachment apparatus, inc...

Materials and Methods: 1391 individuals (age 45-64 years old) randomly selected from Dental Atherosclerosis Risk in Communities Study (Dental ARIC). Clinical measures collected included PD, CAL on six sites for all teeth. Case definition of periodontal disease consists of following three degrees; 1) severe periodontitis: >2 interproximal sites ( not on same tooth) with > 6mm CAL and 1 or more i...
