With the development of new dental restorative materials, advances in adhesive dentistry, better understanding of the caries process, the tooth’s potential for remineralization and changes in caries prevalence and progression; the management of dental caries has evolved from G.V. Black’s “extension for prevention” to “minimally invasive.” This concept includes early detection of lesions; indivi...
Numerous lines of evidence have conclusively established the role of sugars in caries etiology and the importance of sugars as the principal dietary substrate that drives the caries process has not been scientifically challenged. While sugars appear to differ little in acidogenic potential, sucrose has been given special importance, as the sole substrate for synthesis of extracellular glucans. ...
Dental caries remains the most common chronic childhood disease. Despite strong evidence of genetic components, there have been few studies of candidate genes and caries. In this analysis we tried to assess genetic and environmental factors contributing to childhood caries in the Iowa Fluoride Study. Environmental factors (age, sex, race, tooth-brushing frequencies and water fluoride level) and...
OBJECTIVE This study evaluated the correlation between laser fluorescence readings and the extent of incipient occlusal caries as measured by the volume of tooth preparation in vitro. MATERIALS AND METHODS One hundred and three permanent molars and premolars containing incipient occlusal pit-and-fissure caries and sound occlusal surfaces (1/4 of the sample, control) were selected. DIAGNOdent ...
Introduction: The development and progress of computerized technologies has revolutionized radiology with digital imaging. The aim of this study is to compare Digital Radiography(DR) and Temporal Digital Subtraction (TDS)in detection of dentinal caries progression. Methods: 27carious teeth were placed in separate vials of sterile buffer solution after extraction .Three radiopaque restorations ...
Objective: To determine the caries pattern of tooth surface children at SDN Mangaran 2 in Kebun Renteng Jember. Methods: Descriptive observational with a cross sectional approach. The sample were students class I-III totaling 38 total sampling technique. data discussed descriptively and presented tabular form. Results: Caries primary teeth was more common on mesial least facial or buccal surfac...
Lamellae or cracks are distributed throughout tooth enamel in both deciduous and permanent dentitions. While earlier authors postulated that lamellae may be pathways of entry for caries, no evidence was adduced and the theory appears to have been discounted. The present study seeks to show that, at least in some cases, lamellae are permeable to dyes, may be associated with caries initiated in t...
Dental research gives rise to data with potentially complex correlation structure. Assessments of dental caries yield a binary outcome indicating the presence or absence of caries experience for each surface of each tooth in a subject's mouth. In addition to this nesting, caries outcome exhibit spatial structure among neighboring teeth. We develop a Bayesian multivariate model for spatial binar...
