Question: Do the biomechanical properties of the diet influence the tooth shape of insectivores? We examined dietary ‘intractability’, the extent to which structural strength, toughness and stiffness of a food are increased, roughly equivalent to ‘hardness’. Hypotheses: The following three factors may cause discrepancies in tooth form in animals with different diets: (1) optional functional for...

Since the advent of post and core systems, dentists have regularly accepted the traditional cast and post and core as choice of treatment modality to restore a badly broken root canal treated tooth. The important question being, if at all the cast, post is indicated in every case.

PURPOSE To search if the shear bond strengths of brackets would change after two different base-cleaning procedures such as sandblasting or carbide bur cleaning, and to determine if a previously bonded tooth surface had any effect on bond strength. MATERIALS AND METHODS A total of 120 new brackets were first bonded to 120 extracted premolars and then debonded and bond strength was recorded. T...

BACKGROUND Traumatic injuries caused to anterior teeth are most common. Emergency management of fractured fragments is necessary, for preserving their vitalities and for retaining aesthetics in an economical way. Various methods are available for restoring fractured, uncomplicated teeth, such as reattachment of fractured fragments, composite restoration. But only limited data is available on ev...

BACKGROUND This study compared the shear bond strength of metallic brackets bonded with Single Bond and Assure bonding agents under dry and saliva-contamination conditions. METHODS Sixty sound premolar teeth were selected, and stainless-steel brackets were bonded on enamel surfaces with Single Bond and Assure bonding agents under dry condition or with saliva contamination. Shear bond strength...

Gears are an integral and necessary component in our everyday lives. Most of the work performed in plastic and metal but very few works available in combine effect of plastic and metal gears. The main problem while referring plastic gear is the bending strength and in case of metal gear is cost. Hence, the work is performed on metal plastic composite gear to get benefit of both. Here use the co...

Background: The debonding of acrylic teeth from the denture base is a challenging problem to the dentist and dental technician in which special means must be done to increase the debonding strength of the tooth. Material and method: Sixty specimens of acrylic central incisors were attached to acrylic rods and grouped into 5 groups according to the shape of the retention means placed at the toot...

QUESTION What is the effect of wearing splints at night to stretch the plantarflexors on dorsiflexion range of motion (ROM) in people with Charcot-Marie-Tooth disease? DESIGN Randomised, assessor-blinded, cross-over trial. PARTICIPANTS 14 people (1 dropout) aged 7 to 30 years with Charcot-Marie-Tooth disease Type 1A and with < or = 15 degrees dorsiflexion range of motion (ROM). INTERVENTI...

INTRODUCTION Tooth preservation in adults and children is one of the Healthy People 2020 goals for oral health. Although the overall prevalence of tooth loss has been declining in the United States, substantial racial/ethnic differences in preventable tooth loss persist as a public health problem. We examined the strength of the association of health risk factors and tooth loss in Hawai'i. ME...
