Objective: The human body has evolved to maintain homeostasis through the covering of skin and mucous membranes, which separate the internal environment from the harsh and variable external milieu. Few structures naturally penetrate these coverings, and teeth are the only exception in human beings. Dental enamel and root cementum at the cervical region is of interest since that area represents ...

INTRODUCTION Dental caries is a major public health problem, and Streptococcus mutans is considered the main causal agent of dental caries. This study aimed to compare the effect of three re-mineralizing materials: resin infiltrant, fluoride varnish, and nano-hydroxy apatite paste on the surface hardness and adhesion of Streptococcus mutans as noninvasive treatments for initial enamel lesions. ...

PURPOSE To find the most appropriate Er:YAG laser parameters for an optimal marginal adaptation of Class V restorations in enamel and dentin. METHODS Six saucer-shaped mixed Class V cavities were prepared in each of the eight experimental groups with an Erbium:YAG hard laser (Opus Duo) on extracted human molars in near contact mode with a conical 800 microm sapphire tip under continuous water...

This study evaluated the shear bond strengths and etching patterns of seven self-adhesive resin cements to human enamel specimens which were subjected to one of the following surface treatments: (1) Polishing with #600 polishing paper; (2) Phosphoric acid; (3) G-Bond one-step adhesive; or (4) Phosphoric acid and G-Bond. After surface treatment, the human incisor specimens were bonded to a resin...

BACKGROUND Air-abrasion can be used for enamel preparation before fissure sealing as well as acid etching which is the evidence-based method for enamel preparation before sealing. AIM The aim of this study is to evaluate the status of sealed occlusal surfaces of the first permanent molars after one, two, and five years and to compare consequence of using the two different methods for enamel p...

Bonding composite resin to enamel of teeth affected by amelogenesis imperfecta (AI) is often problematic, especially in cases with poorly mineralized, friable enamel. Difficulty in bonding hypomineralized enamel can significantly limit the restorative and orthodontic treatment options for AI patients. In this report, we document a novel approach to bonding AI enamel by pretreating the tooth sur...

Dens evaginatus is a developmental anomaly that is characterized by occurrence of an extra cusp-like structure projecting from the crown portion of the tooth. Unusual extension of enamel has been found in posterior teeth as enamel pearl or as cervical enamel extensions from the cementoenamel junction or at the furcation areas. We hitherto report a case of extra enamel formation from the proxima...

background: the aim of this clinical trial study was to clinically evaluate the use of enamel matrix protein derivative combined with the coronally positioned fl ap to treat gingival recession compared to the subepithelial connective tissue graft by a new method to obtain denuded root surface area. materials and methods: thirteen patients, each with two or more similar bilateral miller class i ...

polyacrylonitrile (pan) membranes with nano-porous surface and high hydrophilicity were fabricated by addition of polyoxyethylene (40) nonylphenyl ether (igepal) as an additive in the casting solution. the membranes were prepared from pan/igepal/1-methyl-2-pyrrolidone (nmp) via phase inversion induced by immersion precipitation technique. pure water was used as coagulation medium. the effects o...
