Non-carious cervical lesions are characterized by the loss of dental hard tissue at the cement-enamel junction (CEJ). Exceeding stresses are therefore generated in the cervical region of the tooth that cause disruption of the bonds between the hydroxyapatite crystals, leading to crack formation and eventual loss of enamel and the underlying dentine. Damage identification was performed by image ...

BACKGROUND Management of human teeth has moved from a surgical to a more conservative approach of inhibiting or preventing lesion progression. Increasing enamel mineralization is crucial in this regard. A potential difficulty is the preferential mineralization of the outermost portion of the enamel that can prevent overall mineralization. We describe a strategy for increasing the mineralization...

3 Introduction noticed in whale's tooth by Ploquet in 1794. Salter first described this anatomical anomaly Dens invaginatus is a dental anomaly as “a tooth within tooth” in 1855, and was the which results from invagination of enamel first person who described dens invaginatus in organ into dental papilla, beginning at the 3 ,4 human tooth in 1856. Clinically, a crown and sometimes extending int...

BACKGROUND Objective was to evaluate the in vivo effects of a novel dental gel (Livionex gelR) vs. a comparison dental gel on the surfaces of pre-eroded enamel chips. METHODS On days 1-5, after toothbrushing with dentifrice, nine subjects each wore 8 enamel chips mounted on a palatal appliance for 4 h. Enamel blocks were pre-demineralized daily. After 2 day washout, subjects repeated the prot...

Patients with Axenfeld-Rieger Syndrome (ARS) present various dental abnormalities, including hypodontia, and enamel hypoplasia. ARS is genetically associated with mutations in the PITX2 gene, which encodes one of the earliest transcription factors to initiate tooth development. Thus, Pitx2 has long been considered as an upstream regulator of the transcriptional hierarchy in early tooth developm...

BACKGROUND AND AIM: Sesame has a high content of calcium. Regarding to the lack of adequate data about its remineralizing potential, we conducted this study to evaluate the surface hardness of enamel exposed to sesame extraction gel in comparison to artificial saliva and fluoride.METHODS: After mounting and polishing twenty-four caries-free human premolars, the baseline microhardness was record...

OBJECTIVE To verify the relationship between lead concentration in the enamel of deciduous teeth and the presence of enamel defects and, consequently, with dental caries among preschool children. METHODS The sample consisted of 329 preschool children in Piracicaba, State of São Paulo: 132 attending municipal kindergartens close to industrial plants and 197 attending kindergartens in non-indus...

AIM This paper addresses the need of the dental literature to document cases of Glycogen Storage Disease (GSD) type Ib with focus on the paediatric management of oral and dental problems and the potential complications arising from the increased susceptibility to bacterial infections, cariogenicity, and blood diathesis. METHODS Previous medical and dental papers on GSD type Ib published from ...

Like other types of human teeth, the permanent first molar (PFM) has important masticatory function. Since its development and eruption is almost predictable, and the tooth can resist taphonomic conditions, it can form part of possible materials for use in forensic dentistry. The enamel, which forms the coronal outer covering of the tooth, is the hardest tissue of the tooth and is seen with lus...

Background and Purpose: Fluoride is a natural element essential for human nutrition due to its  benefits for dental enamel. It is well-documented that standard amounts of fluoride in drinkingwater can decrease the rate of dental caries. This study was conducted with the aim of measuring fluoride concentration of drinking-water supplies and urban distribution system in Qom, I...
