A case of mucosal burn during the placement of fissure sealant on the first permanent molars of a 9-year-old Malay boy is presented. The erythematous lesion with accompanying burning sensation appeared a few minutes after the etching liquid, containing 37% by weight phosphoric acid, had accidentally come into contact with the buccal mucosa on the right side of the angle of the mouth. The mucosa...

INTRODUCTION/AIM To appraise the clinical literature in determining whether loss of complete sealant retention as surrogate endpoint is directly associated with caries occurrence on sealed teeth as its clinical endpoint and to apply the appraised evidence in testing the null-hypothesis that the retention/caries ratio between different types of sealant materials (resin and glass-ionomer cement) ...

Earlier studies have reported extensive volumetric loss of fissure sealant shortly after placement. To determine the volume of fissure sealant lost at six months, we used a servohydraulic profilometric apparatus in combination with computer graphics. Twenty-two premolar teeth were selected, and baseline silicone impressions were made of each tooth. The teeth were sealed and the occlusion adjust...

Aims. To ascertain whether deproteinization pretreatment of molar-incisor hypomineralization (MIH) enamel affects resin sealant infiltration. Design. Thirty one extracted MIH teeth were divided into three sections and randomly allocated into the Control (etch and FS), Treatment 1 (5% NaOCl, etched and fissure sealed), and Treatment 2 (5% NaOCl and fissure sealed with no etch) groups. Two hundre...

BACKGROUND AND AIMS Marginal seal of the material is extremely important in fissure sealant therapy. The aim of this study was to investigate microleakage of flowable composite resins and conventional fissure sealants with or without dentin bonding agent. MATERIALS AND METHODS The occlusal surface of 60 intact extracted human premolars, divided into four groups, were cleaned with pumice/slurr...

Introduction: It was to compare the efficacy of semiannually fluoride varnish application versus pit and fissure sealant to reduce occlusal caries incidence. Materials and methods: A randomized parallel designed study was conducted with 352 child-ren aged 6-7 years. Participants were allocated into biannual application of varnish (n=179) (NaF 5 %( Durafluor, DENTSPLY®, Latin America) or re...

Physical properties such as surface hardness of dental materials are directly linked to their clinical behavior. The aim of this study was to investigate the influence of extended curing time on the polymerization depth offluoride-containing materials used as pit and fissure sealants. Conventional and extended exposure times (20 and 60 seconds) were used to photoactivate a gold-standard pit and...

UNLABELLED ATM: Oral health is important for everyone, but specially for children and people requiring special care owing to impaired manual ability. Primary prevention, with correct oral hygiene, proper diet, use of fluoride and pit and fissure sealants, can reduce caries risk thereby improving patients' quality of life. The first aim of this paper was to assess the marginal microleakage of di...
