Idiopathic attrition of primary maxillary central incisors: a case report.
A case of idiopathic attrition of Primary Maxillary Central Incisors in a five year old girl is reported.
Congenital insensitivity to pain (hereditary sensory and autonomic neuropathy) HSAN: a report of two cases.
Pain is one of the protective phenomenon possessed by the body. Pain arouses and demands our immediate attention. There are instances in which there is a congenital insensitivity to pain. Two cases of congenital insensitivity to pain are reported.
Comparison of levels of mutans streptococci and lactobacilli in children with nursing bottle caries, rampant caries, healthy children with 3-5 dmft/DMFT and healthy caries free children.
Ten children from each group of nursing caries, rampant caries, 3-5 dmft/DMFT and caries free children were selected and plaque samples from carious lesion, early carious lesion, sound tooth surface as well as salivary sample were collected. The levels of mutans streptococci and lactobacilli were estimated at all the sample sites. The result further supported the role of mutans streptococci in the initiation and of lactobacilli in the progression of the dental caries.
Comparison of resin-dentine interface in primary and permanent teeth for three different durations of dentine etching.
Hybridization of dentine is identified as a basic bonding mechanism between resin and dentine, hence studying the micro morphology of hybrid layer may explain lower bond strength that has been observed in primary teeth. The aim of the present study was to compare the thickness and micromorphology of Hybrid layer formed in primary and permanent teeth for 3 different durations of dentine etching time (5, 10 and 15 sec) with 10% phosphoric acid as etchant. Thickness and micromorphology of hybrid layer was observed on SEM photographs obtained at 750X. Results indicated that primary teeth presented with a significantly thicker hybrid layer compared to permanent teeth at 10 sec (P<0.05) and 15 sec (P<0.01) of dentine etching. It was concluded that owing to the high reactivity of primary teeth to etchants, the etchants be applied for shorter period on primary dentine compared to permanent dentine for better performance of composite restoration in primary dentition.
