background: microleakage is still one of the defects of resin composites that can lead to treatment failure; and re-bonding technique is one of the effective ways to reduce it. this study evaluated the effect of re-bonding with a surface sealant or a dentin adhesive on microleakage in class v microhybrid, nanohybrid, and packable composite restorations. materials and methods: in this in vitro s...

AIM Aim of this study was to evaluate the marginal microleakage of a dental sealant using different pre-treatment techniques of the enamel surface. METHODS Thirty extracted human intact teeth were selected and divided into 3 groups (n = 10) (1: acid etching with 37% orthophosphoric acid - 3M ESPE, St. Paul, Minnesota, USA; 2: air abrasion; 3: air abrasion + acid etching). The sealant (Heliose...

AIM To evaluate the remineralization potential of Amorphous Calcium Phosphate (ACP) and Fluoride containing pit and Fissure Sealants using Scanning Electron Microscopy. MATERIALS AND METHODS Thirty maxillary first premolars were divided into three groups of ten each and were randomly selected for ACP containing (Aegis- Opaque White, Bosworth Co. Ltd.), Fluoride containing (Teethmate F1 Natura...

Sealing occlusal pits and fissures in teeth is a common and highly effective preventive method. The main purpose of sealing the pits and fissures is to prevent plaque microflora and food debris accumulation in the fissures where saliva cannot reach and clean the debris, re-mineralise initial lesions, and buffer the acid produced by cariogenic bacteria. Resin-based sealants, as well as glass ion...

This paper reviews the literature and discusses the latest updates on the use of pit and fissure sealants. It demonstrates the effectiveness of pit and fissure sealants in preventing caries and the management of early carious lesions. It compares the use of different sealant materials and their indications. It describes the application technique for sealants. It also reviews the cost-effectiven...

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...

PURPOSE Since properly placed and retained sealants can reduce the incidence of caries lesions and save subsequent restorative costs, the purpose of this study was to compare the subsequent restorative cost in a group of predominantly African American Medicaid children who received prior sealants to that of a group of children who did not receive sealants. METHODS Dental claims of 2 cohorts o...

Examination of sealants recovered at their moment of failure offers clues to factors which played a role in failure. The fitting surfaces of 10 failed sealants recovered immech’ately after placement, and 14 winch had failed after several months in the mouth were examined by scanning electron microscopy. Large areas of the fitting surfaces were smooth, with only localized regions showing evidenc...

The effect of sealant placement and sealant loss on caries-like lesion formation was studied using an artificial caries technique and polarized light microscopy. The results indicate that lesion formation does not occur subjacent to an intact sealant. Even enamel which had lost is sealant was found to be caries-free. It is concluded that resin tags may be responsible for the ability of sealants...
