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...

  Objective: Amorphous calcium phosphate (ACP) is a reactive solution capable of releasing calcium and phosphate ions, conversion to apatite and remineralization of mineral tooth structure. This study reviews ACP structure, its properties and its applications in dentistry.   Methods: In this review study, keywords including “amorphous calcium phosphate”, “mineralization”, “hydroxyapatite”, “cas...

This paper discusses the role of dental biofilm and adjunctive therapies in the management of dental caries. Dental biofilm is a site of bacterial proliferation and growth, in addition to being a location of acid production. It also serves as a reservoir for calcium exchange between the tooth and saliva. The salivary pellicle, a protein-rich biofilm layer, regulates the reaction between tooth s...

In the present study the mineral loss/gain (∆Ca) in dental enamel during de-/ remineralization process, depending on used fluoride concentration, were measured in vitro in pH cycling conditions. 20 sound premolars extracted for orthodontic reasons were divided in 4 subgroups. Artificial lesions were created on each of them. They were all subject to a pH cycling regimen for 2 weeks. During the p...

This study investigated the feasibility of using a digital image analysis system to process the information contained in microradiographs of tooth sections that included dental caries lesions. The results show that by using an aluminum step wedge to provide a range of thickness standards and a sound area of the sample as an internal reference, data on tooth mineral content as a function of the ...

Objectives: The aim of this study was to evaluate the effectiveness of casein and hydroxyapatite on remineralization of white spot enamel lesion and assessment by a new caries detection device, FluoreCam System (Thereametric Co., Indianapolis, USA). Study Design: Demineralized human enamel specimens were measured for baseline surface by the following methods; micro hardness, Quantitative Light ...

Dental caries is a multifactorial disease caused by the interaction of dietary sugars, dental biofilm, and tissue host. It results from repeated cycles demineralization remineralization at interface biofilm tooth surface. Demineralization process removing mineral ions hydroxyapatite crystals in hard tissues, such as enamel, which can lead to if left unchecked. The reverse lost that occur during...

The purpose of the present study was to investigate whether fluoride (F) ions are really capable of the repair (remineralization) of damaged crystals and useful for reinforcing the quality (i.e. modify the crystal structure) of tooth enamel using transmission electron microscopy and Raman microprobe analysis. Additionally, carbonic anhydrase activity was measured in immature enamel tissue to co...

statement of the problem: with the recent focus of researches on the development of non-invasive treatment modalities, the non-invasive treatment of early carious lesions by remineralization would bring a major advance in the clinical management of these dental defects. casein phosphopeptide-amorphous calcium phosphate (cpp-acp) is considered to be effective in tooth remineralization. purpose: ...
