PURPOSE The purpose of this study was to assess the performance of sealants placed by senior dental students as part of a comprehensive dental care program that included periodic patient recall. METHODS The dental records of 100 patients ranging in age from 6 to 13 years were selected for review to determine the treatments provided for first permanent molars over time. Criteria for inclusion ...

Previous studies have shown that near-infrared (NIR) reflectance and transillumination imaging can be used to acquire high contrast images of early caries lesions and composite restorative materials. The aim of the study was to determine the optimum NIR wavelengths for imaging demineralized areas under dental sealants. Fifteen natural human premolars and molars with occlusal lesions were used i...

BACKGROUND Bonding agents could be used as fissure sealants. This study compares the retention three fissure sealants (Delton, Delton Plus and Concise) and a filled dentin bonding system (Optibond Solo). METHODS. Fifty-six children aged 7-8 years received fissure sealants either in the four permanent first molars, in the four deciduous second molars, or in all eight of these teeth. Every child ...

objective: the aim of this study was to evaluate the efficacy of enamel bonding agents on pit and fissure sealant retention in a well-isolated situation. materials and methods: thirty-two patients (6-9 years old, all males) with four fully erupted permanent first molars were selected. their occlusal, buccal, and lingual fissures were sealed according to a split-mouth design using concise light ...

A nonprofit private dental clinic provides free dental treatment for children up to the age of eighteen years. In order to expand its services to reach more children, a school-based sealant program using dental auxiliary personnel was organized. This paper evaluated the performance of the school-based program during 1991 by comparing the costs of the school-based program with the costs of the s...

AIM Aim of this study was the evaluation of the microhardness of 4 dental sealants polymerised with two different curing units. METHODS Twenty samples (5 x 5x 2 mm) were prepared with 4 different sealants; 10 samples for each group were polymerised with a plasma curing unit (Apollo 95 E DMD) and 10 with a halogen curing light (Heliolux DLX Vivadent ETS, Schaan, Liechtenstein). For each sectio...

PURPOSE The purpose of this 10-year, retrospective, cohort study was to evaluate the success of permanent molar sealants by comparing the effectiveness of sealants placed by dentists, dental hygienists, and dental assistants in a private dental practice, with all operators using an identical, standardized, application technique and 4-handed dentistry. METHODS From 810 patient records that met...

Neurocutaneous syndrome (NCS), a newly discovered toxicity disorder, is described in light of our new understanding of its relationships with the causative agents included in the dental liners used in afflicted patients. NCS is characterized by neurological sensations, pain, depleted energy and memory loss as well as itchy cutaneous lesions that may invite various opportunistic infections. Comp...

Although dental caries has been declining in permanent teeth for many children since the 1960s, previous findings showed caries in primary teeth for preschool children increasing from 24% to 28% between 1988 and 2004. Disparities in caries continue to persist for some race and ethnic groups in the United States. Prevalence of dental sealants--applied to the tooth chewing surfaces to help preven...

CONTEXT Dental sealants and composite filling materials containing bisphenol A (BPA) derivatives are increasingly used in childhood dentistry. Evidence is accumulating that BPA and some BPA derivatives can pose health risks attributable to their endocrine-disrupting, estrogenic properties. OBJECTIVES To systematically compile and critically evaluate the literature characterizing BPA content o...
