The demineralization kinetics of deproteinized lobster shells using CO2 were studied. Demineralization reaction proceeds until the concentration of Ca+2 in solution reaches an equilibrium value. The introduction of a cation exchange resin (cationite), in an open system for CO2, allows replacement of the solution Ca 2+ ions by Na+ ions, whereby the equilibrium shifts and an effective dissolution...

Introduction: The oral cavity and the teeth are frequently subjected to numerous physiological pH variations, mainly due type of diet. These changes main cause enamel demineralization consequent breakage under mechanical forces. This causes severe sensitivity sometimes pain, which endures unless hard tissue is remineralized. Since does not self-repair, application alloplastic materials that hav...

AIM: The objective of this in vitro study was to evaluate the effects of new dentifrices containing 1.5% arginine, an insoluble calcium compound, and fluoride for their ability to promote remineralization of demineralized enamel. Methods: Twenty human premolar extracted for orthodontic reasons were used. The specimens were immersed in demineralization solution followed by application of proargi...

Enamel and dentin are susceptible to acids from food sources leading dental erosion, a global problem affecting millions of individuals. Particulate hydroxyapatite (HAP) on the tooth surface can influence effects acid attacks. Standardized bovine enamel samples with artificial saliva used in an vitro cyclic demineralization–remineralization protocol analyze structural changes experienced by sur...

Dental caries is the leading cause of tooth loss, which can promptly be prevented if detected in early stages of progression. Unfortunately, conventional diagnostic modalities currently used in dentistry lack the sensitivity to detect early caries. The authors' intention is to compare the ability of polarized Raman spectroscopy and thermophotonic imaging to make early caries diagnosis. Extracte...

The initial detection of dental caries is an essential biomedical requirement to barricade the progression of caries and tooth demineralization. The objective of this study is to introduce an optical frequency-domain imaging technique based quantitative evaluation method to calculate the volume and thickness of enamel residual, and a quantification method was developed to evaluate the total int...
