The objective of this paper is to critically review the literature regarding the mechanics, geometry, load application and other testing parameters of "micro" shear and tensile adhesion tests, and to outline their advantages and limitations. The testing of multiple specimens from a single tooth conserves teeth and allows research designs not possible using conventional 'macro' methods. Specimen...

Introduction. It is widely acknowledged that the behavior of parents affects their children's health. This study aimed to evaluate the relationship between oral health behavior of parents and oral health status and behavior of their children in a sample of preschool children in Iran. Method and Material. A random sample of over-five-year-old preschool children and their parents were enrolled in...

Received July 10, 2006 Abstract Objectives: To briefly outline the development and reasons for the decline in the clinical use of tetracyclines, and to consider if the side-effects of doxycycline a contra-indication to its use. Data Sources: Literature search of MEDLINE from 1950 to 2005. Study Selection: Literature and data related to doxycycline, tetracycline and tooth discolouration. Data Ex...

OBJECTIVES The aim of this review was to critically analyze the empirical evidence on the association between Sense of Coherence (SOC) and oral health behaviors through a systematic approach. METHODS A systematic search up to April 2015 was carried out using the following electronic bibliographic databases: PubMed, Ovid MEDLINE; ISI Web of Science; and Ovid PsychInfo. Studies were included if...

abstract the attrition of anterior teeth leads to the loss of efficient anterior guidance, which protects posterior teeth from wear during lateral excursions. this clinical report describes a 48-year-old man with diagonal tooth wear and posterior mandibular tooth loss. the clinical diagnosis was based on a complete oral examination, photos, functional analysis of lateral excursion movements, ge...

The tooth is an ectodermal organ that arises from a tooth germ under the regulation of reciprocal epithelial-mesenchymal interactions. Tooth morphogenesis occurs in the tooth-forming field as a result of reaction-diffusion waves of specific gene expression patterns. Here, we developed a novel mechanical ligation method for splitting tooth germs to artificially regulate the molecules that contro...

Bone-anchored appliances for the treatment of Class III malocclusions have recently been found to reduce dentoalveolar effects caused by conventional tooth-borne devices while also improving orthopaedic outcomes in growing patients. The goal this systematic review was compare skeletal interceptive with dental anchoring those achieved mixed anchored palatal expanders. inclusion criteria were as ...

The reasonable selection of three-dimensional roughness parameters can evaluate the service performance machined surface, and its excessively high dimension greatly increases difficulty selection. In order to reveal correlation law between 3D tooth surface contact parameters, analysis theory is used explore correlation, nonlinear mapping model constructed by using BP neural network, genetic alg...

Background: The selection of shade a tooth is routine practice for dentist, especially prosthodontist, to make esthetically pleasing prostheses. The phenomenon colour matter perception by the eye. Every opaque object receives light, absorbs some it and reflects rest. A being an object, amount light. dominant wavelength this reflected light discerned us as tooth. Ligh...
