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 ...

PURPOSE The purpose of this in vitro study was to evaluate microleakage of pit and fissure sealants after using three different pit and fissure preparation techniques: (1) traditional pumice prophylaxis and acid etching, (2) fissure enameloplasty and acid etching and (3) air abrasion and acid etching. METHODS Sixty extracted third molars with no clinical evidence of caries were randomly divid...

BACKGROUND The success of pit and fissure sealants is directly related to their retention. The purpose of this study was to assess and compare the retention of pit and fissure sealants placed using acid etch alone and a combination of air abrasion and acid etch techniques. MATERIAL AND METHODS 50 subjects aged 6-8 years were included in the study. Primary second molars and permanent first mol...

BACKGROUND The relative performance of ART sealant and fluoride-releasing resin sealant in preventing fissure caries in permanent molars was compared in a randomized clinical trial conducted in southern China (ClinicalTrials.gov NCT01829334). METHODS After obtaining ethical approval, healthy schoolchildren who had permanent first molars with occlusal fissures which were sound but deep or pres...

Aims and objectives: The aim of this in vitro study was to evaluate self-adhering composite Dyad flow (Kerr, USA) as a pit and fissure sealant. The objectives were to assess the degree of microleakage with self-adhering composite Dyad flow and that with Fissurit F as pit and fissure sealants and, to compare the same between these two materials. Materials and Methods: 20 premolars extracted for ...

Objective: Radio-opacity is a fundamental requirement for fissure sealants in order to be clearly visible radiographicallyand may be well differentiated from caries. Many attempts have been made to make resin based fissure sealants radio-opaque. Researchers achieved radio-opacity of the sealants by blending heavy metals as fillers into the polymeric matrix. Keeping the demerits of using heavy m...

OBJECTIVE This study evaluated the effectiveness of sealant retention and caries prevention with and without primer and bond below the fissure sealant among Kuwaiti schoolchildren. SUBJECTS AND METHODS This clinical trial used fissure sealant that was applied to four sound first permanent molars on 78 children. All the teeth were cleaned with pumice and rubber cups, isolated with rubber dams,...

May/June 2002 This article focuses on the techniques used for successful pit and fissure sealant application by the dental assistant. Pit and fissure sealants first were utilized in 1967 and formally recognized by the American Dental Association in 1971. Since that time, many product developments have been introduced to increase their effectiveness and ease of use. Finding adequate time in the ...

UNLABELLED The penetration of a sealant into the tooth fissures can establish longer retention time for a pit and fissure sealant restoration. AIM This in vitro study was to evaluate the penetration ability of two low-viscosity resin materials, a composite and a compomer, applied with and without their bonding agents in comparison to an unfilled resin sealant. METHODS Forty premolars with s...

The clinical behavior of Concise and Prisma Shield sealants for pit and fissure was analyzed by clinical/photographic evaluation. A hematoxylin-based staining solution was applied to the occlusal surface 7 days, 18 months, 36 months, and 11 years after the occlusal sealing, thus allowing the sealant material on the surface to be checked. At each analysis time, each occlusal surface was photogra...
