Objectives: In this article, we report two cases of type I dentin dysplasia (DD): the first case is subtype “d” DD and second case is severe form of DD type I, which presents all of four subtypes and describes characteristics and the management of this type of teeth anomalies. Materials and methods: Dentin dysplasia is a rare abnormality of dentin that involves both primary and permanent dentit...

OBJECTIVES The aim of this study was to evaluate the performance of a visual-tactile examination and a laser fluorescence device for detecting residual dentinal caries after carious dentin removal with bur excavation, hand excavation and chemomechanical excavation (Carisolv()]. METHODS Thirty extracted coronal caries primary second molars were used. The caries infected dentin has been removed...

introduction: this study investigated the sealing ability of three different adhesives in primary bovine teeth. methods: facial and lingual class v cavities were prepared half in enamel and half in cementum, in 48 bovine primary mandibular incisors and randomly divided into three groups and each group divided to two subgroups. the tested adhesives were xpbond (xp), clearfils3 bond (s3), and xen...

background: glass ionomer cement is a common material used in pediatric dentistry. the aim of this study was to evaluate the microleakage of high-viscosity glass ionomer restorations in deciduous teeth after conditioning with four different conditioners. materials and methods: fifty intact primary canines were collected. standard class v cavities (2 mm × 1.5 mm × 3 mm) were prepared by one oper...

To evaluate the effect of a dentin adhesive on sclerotic dentin, contraction gap width and shear bond strength were measured. Dentin cavity wall was pretreated with an experimental dentin bonding system with and without a dentin primer, or with a commercial dentin bonding system. In the experimental dentin bonding groups, contraction gap width of sclerotic dentin was significantly smaller than ...

abstract introduction: the mineral content of dentin increases with age and its primary structure is altered. these changes may have unknown effects on efficiency of adhesive systems. the aim of this study was to find the effect of aging on dentin bonding agents. methods and materials: fourty eight extracted human premolars were divided into 2 groups under 15 years old & 2 groups over 45 years ...

Preventive measures have helped to minimize the occurrence of dental caries. However, premature loss of primary teeth on account of dental caries still remains a common problem among children. The pulpotomy technique has been the choice for treating vital primary and young permanent teeth with carious, mechanical and traumatic pulp exposures. The ideal pulpotomy medicament should be bioinductiv...

This article describes a technique for restoring Class V carious lesions in the primary dentition. The discussion will include the treatment of aprismatic enamel in primary teeth, bonding to dentin, and the restorative techniques that are available for composite bonding. A case report is presented that utilizes several modern techniques for restoring Class V lesions.

Objectives: This study aimed to investigate dentinal crack rate following parapulpal pin insertion in anterior primary teeth. Methods: Thirteen sound freshly extracted primary canine teeth were horizontally sectioned 1 mm above the cementoenamel junction (CEJ). All samples were thoroughly inspected to ensure that the teeth had no cracks. The teeth were then mounted in acrylic blocks...

The aim of this study was to evaluate the microtensile bond strength (microTBS) and the elemental contents of the adhesive interface created to normal versus caries-affected dentin. Extracted human molars with coronal carious lesions were used in this study. A self-etching primer/adhesive system (Clearfil Protect Bond) was applied to flat dentin surfaces with normal and caries-affected dentin a...
