Early diagnosis of dental caries is paramount importance. If we are able to intercept lesion at subsurface level with the help remineralizing agents, can actually achieve a free mouth.Remineralization was ruled by fluorides from 1960s. Since then it has been successfully carious lesions & certain disadvantages like dependant on calcium and phosphate saliva accomplish this. Also overuse caus...

OBJECTIVE To study and compare the effects of different demineralization-inhibition methods on the shear bond strength (SBS) and fracture mode of an adhesive used to bond orthodontic brackets to demineralized enamel surfaces. METHODS Eighty freshly extracted, human maxillary premolars were divided into 4 equal groups and demineralized over the course of 21 days. Brackets were bonded to the de...

Adhesive restorations are based on the use of materials, which have the capacity to bond tooth effectively. This is possible due to a polymerizing hybrid layer interface created by the use of the Etch&Rinse (ERAs) and self-etching adhesives (SEAs). Bonding using ERAs include the acid-etching removal of the mineral phase from the substrates of enamel and dentine. A hybrid layer results by fillin...

A range of lasers is now available for use in dentistry. This paper summarizes key current and emerging applications for lasers in clinical practice. A major diagnostic application of low power lasers is the detection of caries, using fluorescence elicited from hydroxyapatite or from bacterial by-products. Laser fluorescence is an effective method for detecting and quantifying incipient occlusa...

OBJECTIVE: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals. METHODS: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were first measured. The bone segments were then divided into four groups of 15 segments each and demineralized in an aqueous 0.5 N hydrochloric aci...

Background: The cause of cavities is initially due to roughness on the tooth surface, requiring fluoride varnish prevent caries, as applies a compound surface. Fluoride reacts with enamel surface form calcium and fluorapatite, thus making more resistant demineralization damage. Purpose: This study aims compare surfaces among three varnishes under acidic conditions. Methods: research method uses...

Optical coherence tomography (OCT) is an interferometric imaging technique. This study aimed to employ OCT to evaluate four different resin-based materials including a coating containing glass-ionomer filler and calcium, a giomer, and two fluoride-releasing self-etch resins. The coating and its underlying and adjacent enamel were monitored using swept-source OCT (center wavelength: 1330 nm) at ...

Dental caries is one of the most common preventable childhood disease; people are susceptible to this ailment throughout the lifetime [1]. Data from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2004 revealed that 28 percent of children ranging from 2 to 5 years of age had one or more primary tooth affected by dental caries and 51 percent of children h...

One common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. Different methods have been used to prevent demineralization such as fluoride therapy and application of sealant to prevent caries. The recent effort to improve the resistance against the demineralization ...
