OBJECTIVE This study was intended to optimize perlite particle size and morphology for better tooth cleaning and lower tooth abrasion, and to evaluate the performance of a whitening toothpaste containing the optimized perlite abrasive for tooth cleaning, abrasion, and polishing. METHODS Perlite toothpaste abrasive samples were prepared by air classifying a commercial expanded perlite product....

We report on a patient with Schimke immunoosseous dysplasia, an autosomal recessive disorder, and review nine patients from the literature. Manifestations include spondyloepiphyseal dysplasia, lymphopenia, signs of defective cellular immunity, and progressive renal disease. This is the first patient known to have the additional findings of thrombocytopenia and microdontia.

OBJECTIVE To explore how many millimeters of tooth size discrepancy (TSD) are clinically significant, to determine what percentage of a representative orthodontic population has such a tooth size discrepancy, and to determine the ability of simple visual inspection to detect such a discrepancy. MATERIALS AND METHODS The sample comprised 150 pretreatment study casts with fully erupted and comp...

The aim of this study was to investigate tooth size and morphology in subjects with unilateral cleft palate (UCLP), bilateral cleft palate (BCLP), and isolated cleft palate (ICP) living in the north of England and to compare these with a control group. The measurements were undertaken retrospectively using dental study casts. To assess tooth size, the mesiodistal and buccolingual dimensions of ...

UNLABELLED Proper diagnosis of tooth size for each patient is critical in treatment planning for aesthetic restorative dentistry. The goal of this study was to determine the clinically relevant range and mean distribution frequency of individual tooth width of the maxillary anterior dentition within a given population of patients. Mean values for restoration of tooth size were not interchangeab...

It is contentious whether size variation among mammalian teeth is heterogeneous or homogeneous, whether the coefficient of variation is reliable, and whether the standard deviation of log-transformed data and the residual of standard deviation on mean variable size are useful replacements for the coefficient of variation. Most studies of tooth size variation have been on mammals with complex-cr...

Orthodontic treatment comprises different phases with unique characteristics and challenges. The orthodontic "finishing" phase is recognized for the multitude of details necessary to achieve an excellent result. In some cases, the finishing phase is very difficult, requiring the production of complicated biomechanical forces to reach a satisfactory orthodontic solution. A high percentage of the...

Introduction: Many epidemiological studies have been conducted to determine the prevalence of the various types of the dental anomalies. The aim of the present study was determination of developmental and acquired dental anomalies in patients attending the faculty of dentistry in Rasht, Iran. Materials and Methods: In this retrospective cross-sectional study, 1224 digital panoramic ra-diographs...
