BACKGROUND AND AIMS Despite the increasing demand for adhesive restorations in pediatric dentistry, polymerization shrinkage and subsequent marginal microleakage remains a problem. The aim of this study was to evaluate of the sealing ability of novel low-shrinkage composite silorane in class V cavity of primary canines in comparison with three types of composite resin. MATERIALS AND METHODS N...

The effect of momentary pretreatment by 35% HEMA solution on the adaptation between dentin and resin material was investigated by measuring wall-to-wall polymerization contraction in a cylindrical dentin cavity. Five marketed bonding agents tested in this study exhibited improved marginal seal when the dentin cavity wall was pretreated by 35% HEMA for a few seconds with the exception of Pyrofi1...

Introduction: Glass ionomer and polycarboxylate cement have different effects on the marginal seal, microleakage, pulp tissue stimulation, and gingival health. The purpose of this study was to assess the effect of these cement on the gingival health of primary molars restored with stainless steel crowns (SSC). Methods: A total number of 34 children were selecte...

OBJECTIVE To evaluate the gingival marginal seal in class II composite restorations using different restorative techniques. MATERIAL AND METHODS Class II box cavities were prepared in both proximal faces of 32 sound human third molars with gingival margins located in either enamel or dentin/cementum. Restorations were performed as follows: G1 (control): composite, conventional light curing te...

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...

OBJECTIVES This study aimed to evaluate the effect of chlorhexidine (CHX) application protocol on durability of marginal seal of class V composite restorations. MATERIALS AND METHODS Class V cavities (4×2×1.5mm) were prepared in the buccal surfaces of 160 human third molars. The teeth were randomly divided into five groups (n=32) of (G1) CHX+rinse+etching, (G2) CHX+etching, (G3) etching+CHX+r...

The success rate of the given fixed partial denture and longevity is depend on tooth preparation usage luting cement under prosthesis. Luting plays an important role in maintaining or securing prosthesis cemented position. should be bio compatible, it non-irritating to underlying structure pulp, maintain adequate marginal seal. In recent days so many newer cements has been introduced dentistry,...

At a time of drastic change in the environment surrounding financial institutions, administrative work centralization aimed at reducing the workload of the back office has propelled the introduction of cost-effective image processing systems geared toward centralized operations. Further, in an effort to prevent forgery, more and more institutions have done away with duplicate seals and are intr...

Background Complete seal at dentin-sealer-core interface of the root canal is required to maintain long-term periapical health. Aim The aim of this in vitro scanning electron microscopic (SEM) study was to determine which of the commonly used root canal sealer among AH-Plus, GuttaFlow, and RealSeal provides a superior marginal adaptation with the dentin in the apical third region of root cana...
