OBJECTIVES This study was conducted to evaluate Yemeni dental practitioners' knowledge and practices concerning fissure sealants. MATERIALS AND METHODS A modified questionnaire consisted of 25-items was distributed to 500 dentists working in Sana'a City. Descriptive statistics and Chi-square/Fisher's exact tests were used for statistical analyses. RESULTS The response rate was 74%. Most of ...

BACKGROUND AND OBJECTIVE The onset and progression of early tooth decay is often preventable with dental sealants. However, occasionally decay progresses underneath the sealant. Current technology does not permit monitoring of potential lesion progression or arrest. Dental sealants themselves mask the visual cues that identify early tooth decay, and radiographs are not sufficiently sensitive. T...

background pit-and-fissure sealants are safe and effective ways to prevent dental caries and are considered as a part of an overall caries-preventive strategy. dental caries are a public health problem and the most common intraoral disease affecting mankind. it is an infectious transmissible disease, with the child patient being at the highest risk. objectives the purpose of this study was to e...

micro-leakage, one of the major reasons for recurrent decays, may lead to uncontrollable flow of liquids, pulp inflammation and peri-apical pathology. the purpose of this in vitro study was to evaluate micro-leakage of pit and fissure sealants after using three different pit and fissure preparation techniques: 1) acid etching, 2) fissure enameloplasty and acid etching, and 3) air abrasion and a...

This paper describes the program structure and strategies being used by the Massachusetts Department of Public Health to promote the utilization of sealants. The program design includes four components: clinical demonstration, consumer education, professional education, and reimbursement. Eighteen Massachusetts neighborhood health centers and six local health departments are participating in th...

Bisphenol A or BPA-based epoxy resins are widely used in the manufacture of commercial products, including dental resins, polycarbonate plastics, and the inner coating of food cans. BPA is a precursor to the resin monomer Bis-GMA. During the manufacturing process of Bis-GMA dental sealants, Bisphenol A (BPA) might be present as an impurity or as a degradation product of Bis-DMA through esterase...

background and aims. newer curing units such as plasma arc can polymerize the sealants in much shorter curing times. the aim of this study was to compare the effect of two different curing units on the micro-leakage of a fissure sealant material. materials and methods. sixty two extracted premolars without caries were randomly divided into two groups of 31 samples. occlusal surfaces of all teet...

The current study was aimed towards evaluating retention of the sealants on the first permanent molars of low socioeconomic class children 5 years post application. Also presence and absence of dental caries was determined. It is a follow up study to evaluate the retention of sealants placed during a randomized control trial conducted in children of low socioeconomic class school of Karachi in ...

The slow adoption of sealants into dental practice is attributed partly to the fact that few prepayment plans pay for sealants. An important concern of insurers is how a sealants benefit will affect premiums. In this analysis, caries rates for various surfaces and teeth, failure rates for both sealants and amalgam restorations, fees and copayments, interest rates, reimbursement policies for rep...

BACKGROUND Concern about inadvertently sealing over caries often prevents dentists from providing dental sealants. The objective of the authors' review was to examine the effects of sealants on bacteria levels within caries lesions under dental sealants. METHODS The authors searched electronic databases for comparative studies examining bacteria levels in sealed permanent teeth. To measure th...
