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 ...

Clinical trials were conducted on the teeth of 148 children to determine the effectiveness of a clearly visible white pit and fissure sealant. A three-year-follow-up study showed a high retention rate for the sealant.

objective: long-term retention of pit and fissure sealants is crucial for their success. this clinical study evaluated the retention rate of a flowable composite resin (filtek supreme xt flowable restorative) compared to a conventional resin-based sealant (concise light cure white sealant) over 12 months. materials and methods: forty subjects aged 6 to 9 years were included in the study. using ...

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...

The resistance of white spot lesions to acid demineralization when etched with phosphoric acid and sealed with a resin material was studied. Artificially created white spot lesions were sealed and re-exposed to an artificial caries medium along with unprotected white spot lesions. Examination with polarized light microscopy revealed continued progression of the unprotected white spot lesions, w...

MATERIALS AND METHODS Forty subjects aged 6 to 9 years were included in the study. Using ...

OBJECTIVE To introduce and assess a system for the delivery of fibroblast growth factor to autologous cartilage grafts using fibrin sealant and analyze whether this "enhancement" results in reduced rates of cartilage resorption and greater preservation of normal architectural features compared with "unenhanced" cartilage grafts. METHODS Auricular cartilage segments measuring 1 cm(2) were harv...

BACKGROUND Sealant application during fixed appliances orthodontic treatment for enamel protection is common, however, reliable data on its durability in vivo are rare. OBJECTIVE This study aims at assessing the durability of a sealant (OpalSeal, Ultradent) for protection against white-spot lesion formation in orthodontic patients over 26 weeks in vivo, taking into account the provision or ab...

We compared fibrin sealant, polydioxanone (PDS) pins and Kirschner wires in the fixation of osteochondral fractures in rabbit knees. Standardised osteochondral fractures of the right medial femoral condyle were made in 56 adult New Zealand white rabbits. There were equal groups of control knees, and those which had Kirschner-wire, fibrin-sealant or PDS-pin fixation. No external immobilisation w...

PURPOSE As a national objective, 50% of US children are expected to have dental sealants on at least one permanent molar by the age of 14 years. The present study was conducted to estimate the prevalence of dental sealants among Alabama Medicaid children and to evaluate the characteristics of the sealant users and non-users so the potential barriers in meeting the year 2000/2010 sealant objecti...
