OBJECTIVES The purpose of this study was to evaluate the performance of both single and double applications of (Adper Prompt L-Pop) self-etching dental adhesive, when used with three classes of light-activated restorative materials, in comparison to the performance of each restorative system adhesive. Evaluation parameters to be considered for the adhesive systems were (a) immediate marginal ad...

CONTEXT Various agents are studied for their remineralization potential. AIM To evaluate the effect of GC Tooth Mousse and Toothmin Tooth Cream on microhardness of bleached enamel. SETTINGS AND DESIGN In vitro- study. METHODS AND MATERIAL Twenty freshly extracted anterior teeth were cut sagittally and impregnated in cold cure acrylic resin. Specimens were kept in artificial saliva to prev...

Dental cementum is a vital tissue which demonstrates continuous apposition throughout the life of the tooth. This study was conduct on 101 impacted and 106 erupted mandibular third molar teeth extracted from healthy patients, aged 18-30 years. The buccolingual ground sections were prepared. The distance between the edges of enamel and cementum were measured with micrometer attached with light m...

background: human endeavors to prevent dental caries have led to the use of different modalities and agents, the most commonly used of which is fluoridated dentifrice. an in situ study was carried out to evaluate the efficacy of fluoridated dentifrices in achieving remineralization of initial caries-like lesions using surface microhardness measurements and to study the qualitative changes by sc...

Using a one-dimensional mathematical model that couples tooth demineralisation and remineralisation with metabolic processes occurring in the dental plaque, two mechanisms for subsurface lesion formation were evaluated. It was found that a subsurface lesion can develop only as the result of alternating periods of demineralisation (acid attack during sugar consumption) and remineralisation (rest...

Dental enamel development occurs in stages. The ameloblast cell layer is adjacent to, and is responsible for, enamel formation. When rodent pre-ameloblasts become tall columnar secretory-stage ameloblasts, they secrete enamel matrix proteins, and the ameloblasts start moving in rows that slide by one another. This movement is necessary to form the characteristic decussating enamel prism pattern...

OBJECTIVE To determine whether micro-computed tomography (micro-CT) could be used to reconstruct ancient dental anatomy accurately and differentiate the enamel from the dentin, as well as to verify whether micro-CT could detect tooth disorders such as attrition or caries accurately. METHODS Micro-CT imaging was performed, using a cone-beam micro-CT specimen scanner, on a 500-year-old human to...

There has been growing recognition of the essential roles of citrate in biomechanical properties of mineralized tissues, including teeth and bone. However, the sources of citrate in these tissues have not been well defined, and the contribution of citrate to the regulation of odontogenesis and osteogenesis has not been examined. Here, tooth and bone phenotypes were examined in sodium-dependent ...
