BACKGROUND The purpose of this study was to investigate and compare three different pit and fissure sealants with different composition to check their effectiveness for sealing ability and microleakage. MATERIALS & METHODS Total 120 therapeutically extracted premolars devoid of any caries, anomalies or morphogenic diversity were collected and distributed equally in three groups (40 in each). ...

A variety of pit and fissure sealants are used clinically to protect the occlusal surfaces of teeth against dental caries. A new chemically activated bis-GMA type sea­ lant, Delton Pit and Fissure Sealant, has recently be­ come commercially available. The Delton Etching So­ lution supplied with the sealant contains 35 per cent orthophosphoric acid. The tensile bond strength of this sealant to e...

AIM To evaluate the effect of amorphous calcium phosphate (ACP)-containing pit and fissure sealant on inhibition of enamel demineralization in vitro. MATERIALS AND METHODS Enamel specimens (n = 75) were prepared using freshly extracted noncarious human third molars. Box-shaped cavities (8 × 2 × 2 mm) on the buccal or lingual surfaces were prepared and restored with resin-based sealant (Concis...

Purpose: To evaluate microleakage of pit and fissure sealant after using four different pit and fissure preparation techniques 1) Pumice prophylaxis and acid etching 2) Fissure enameloplasty and acid etching 3) Self etching adhesive system 4) Air abrasion and acid etching. Methods: Eighty exfoliated primary molars with no clinical evidence of caries were randomly divided into 4 groups of 20 eac...

background: a prolonged life of fissure sealant has always been the target for preventing caries in vulnerable newly erupted teeth. the use of preparatory techniques including bur introduction to the fissures is considered among such improving steps. the aim of this investigation was to compare the microleakage level of fissure sealants prepared by a fissurotomy bur or pumice prophylaxis prior ...

Background: For the prevention of dental caries, fissure sealants application is recommended if pits and fissures are very deep and narrow, creating a physical barrier for the plaque's accumulation, in these specific anatomical areas of the tooth. Aim: This review article about fissure sealant aims to address the main properties, indications, advantages and limitations of fissure sealants that ...

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...
