PURPOSE To evaluate the efficacy and safety of two oscillating/rotating toothbrushes, (Braun Oral-B Plaque Remover-D7 and Braun Oral-B Ultra Plaque Remover-D9) and a manual toothbrush with respect to removing extrinsic dental stain. MATERIALS AND METHODS This randomized, three-way cross-over study investigated 24 subjects entering the trial, which was divided into three, 5-day periods. Over t...

this paper reports multidisciplinary treatment of a dental trauma case to achieve a favorable prognosis. a healthy 14-year-old girl reported avulsion of teeth 11 and 21 which had occurred three months earlier. the initial treatment consisting of replantation with a semi-rigid splint was performed in hospital. at presentation, the patient was still using the semi-rigid splint. the clinical exami...

Objectives: To analyze the effect of risedronate hydrogel on enzyme alkaline phosphatase (ALP) and osteoclast/osteoblast ratio during tooth relapse movement
 Materials methods: The research design is experimental with time series. lower incisors 75 guinea pigs are distally moved using open coil spring. were divided into three groups: without (group A; n = 25); given 250 µmol/L B; 25), 500 ...

Plaque is a soft, colorless deposit containing bacteria that adheres to the surface of teeth and surrounds gingiva other hard surfaces in oral cavity. A disclosing agent selective dye can detect presence dental plaque by changing color so it contrasts with tooth surface. Henna has many properties produce staining. Lawsone main ingredient henna plant. high affinity for binding proteins causing T...

Background and Aim: Management of iron-induced tooth pigmentation is challenging. This study aimed to compare the efficacy of sodium bicarbonate powder and pumice flour for removal of iron-induced pigmentation from primary ante-rior teeth. Materials and Methods: In this in vitro, experimental study, 60 sound primary anterior teeth were collected. After cutting the roots and sealing the pulp ch...

A review of the existing literature was performed by using electronic and hand searching methods for CEM cement from January 2006 to December 2013. CEM cement has a different chemical composition from that of mineral trioxide aggregate (MTA) but has similar clinical applications. It combines the biocompatibility of MTA with more efficient characteristics, such as significantly shorter setting t...

In the course of the previous study entitled " Chronological Study of Enamel Knot with Special Reference to Mitoses in Enamel Knot" the present author noticed the presence of (1) specific spindle cells with nuclei stained darkly with hematoxylin in the vicinity of the enamel knot as well as (2) small granules or globular substances of brownish black or yellowish brown in color in the enamel kno...

INTRODUCTION This study investigated the accuracy of cone-beam computed tomography (CBCT), peripheral quantitative computed tomography (pQCT), spiral computed tomography (SCT), plain (plain digi), and contrast medium-enhanced digital radiographs (contrast digi) in studying root canal morphology. METHODS The root canal anatomy was analyzed in 95 teeth using CBCT, pQCT, SCT, plain digi, and con...

BACKGROUND Bleached dental enamel can be more susceptible to staining than the enamel that has never been bleached, especially right after tooth bleaching. The aim of this study is to evaluate the effect of surface treatments and waiting time prior to contact with dye on bleached enamel staining susceptibility. MATERIAL AND METHODS One hundred teeth were bleached with 35% hydrogen peroxide (W...

Materials and methods: Study One: In February, March, and April of 2009, oral exams were performed on 735 piglets at weaning. Deciduous teeth were recorded as being erupted or not. Occlusion between premolars was noted. A superscript (or subscript) number indicated position within the maxilla (or mandible) of incisors, canines, and premolars (i, c, and p, respectively). Prevalences of tooth dam...
