PURPOSE The objective of this in vitro study was to evaluate the tensile bond strength of three self-etching primers to human primary enamel and dentin. METHODS Forty (40) freshly extracted primary molars were sectioned bucco-lingually and embedded in self-curing acrylic resin with the facial or lingual surfaces exposed. The specimens were wet ground to 600 grit SiC paper to expose a flat ena...

PURPOSE Successful bonding of resins to teeth affected by amelogenesis imperfecta (AI) may be highly dependent on how the enamel responds to acid etching. The aim of this study was to determine, using scanning electron microscopy (SEM), the types of etching pattern achieved with 37% phosphoric acid on dental enamel of 5 clinical variants of AI, namely, pitted hypoplastic, smooth hypoplastic, X-...

AIM This in vitro study compared the effect of a concave with a straight-bevelled cavity margin on the microleakage of Class V composite resin restorations in primary teeth. MATERIALS AND METHODS Standardised Class V cavity preparations were made in vitro on the buccal (all margins placed in enamel) and on the lingual (margins placed in enamel and cementum) surfaces of 20 sound primary molars...

OBJECTIVE The purpose of this study was to determine and compare the prevalence and presentations of developmental defects of the enamel (DDE) in the primary and permanent dentitions of a group of healthy schoolchildren residing in Granada (Spain). STUDY DESIGN A total of 1,414 healthy schoolchildren were examined using modified DDE criteria for recording enamel defects. RESULTS The prevale...

BACKGROUND AND AIMS The objectives of the present study were to investigate the prevalence and the position of enamel defects of primary teeth and hence to estimate the approximate time of an insult. MATERIALS AND METHODS 121 children aged 3 to 5 years were included in the study. The Modified Developmental De-fects of Enamel Index was used to diagnose and classify the defects. The defects wer...

Enamel mineralization is affected by genetic disorders like Down syndrome and familial dysautonomia (FD). Congenital Insensitivity to Pain with Anhidrosis (CIPA) is associated with decreased sensation and autonomic dysfunction, somehow similar to FD. In this study we examined the effect of CIPA on pre and post-natal enamel mineralization of 9 primary extracted teeth and matchpaired normal teeth...

introduction: marginal seal integrity is important for a successful adhesive dental restoration. alterations caused by laser irradiation in the enamel and dentin surface can affect the marginal integrity of adhesive restorations. the aim of this study was to evaluate the microleakage of a composite resin restoration in primary teeth following laser irradiation of enamel and dentin. methods: for...

AIM The aim of this study was to investigate the cementoenamel junction of a group of 11 primary sound mandibular incisors extracted for orthodontic reasons. MATERIALS AND METHODS Eleven caries and defect-free human inferior deciduous incisors were extracted for orthodontic reasons and the cementoenamel junction was investigated by scanning electron microscopy (SEM). The types of tissue inter...

Purpose: To evaluate the erosive effect of pediatric liquid medicinal syrups on primary and permanent enamel. Materials methods: Eighty teeth were equally divided into eight subgroups (n=10), according to immersion solutions: Depakine, Ventolin, Sansovit, Artificial saliva. The cycles drugs conducted under a 1-min agitation three times daily for 28 days. Enamel microhardness measurements taken ...
