background and aims. due to anatomic variation in tooth anatomy between populations, this study compared the buccolingual (bl) and mesiodistal (md) dimensions of primary molars with those of stainless steel crowns (sscs) in an iranian population. materials and methods. impressions were taken from both dental arches of children, and casts were poured. teeth with caries, restoration, hypoplasia o...

This study assessed the pulp healing response to human freeze-dried bone (FDB) in two cynomolgus monkeys using 36 noncarious primary teeth pulpotomized and randomly assigned to three medicaments. FDB was applied on the pulp stumps and covered with sterile tin foil as experimental group. The two other groups received either calcium hydroxide [Ca(OH)2], or IRM (reinforced ZOE). All teeth were res...

The aim of this study was to compare the effect of ferric sulfate (FS) to that of dilute formocresol (DFC) as pulp dressing agents in pulpotomized primary molars. Ninety-six primary molars in 72 children were treated by a conventional pulpotomy technique. Fifty-eight teeth were treated by a FS solution for 15 sec, rinsed, and covered by zinc oxide-eugenol paste (ZOE). In another 38 teeth, a cot...

single rooted primary mandibular first molar is a rare developmental anomaly. literatures reveal that failure of invagination of hertwig's epithelial root sheath leads to this unusual root form. thorough knowledge of root canal morphology and anatomical variations of primary teeth can help a pediatric dentist in successful root canal treatment. hereby, we describe two cases of primary mandibula...

Mortal pulpotomy is the most commonly used technique in Bulgaria for treatment of pulp chronic infections in primary teeth. Data from the special literature reveal another method for pulp treatment in primary teeth – vital pulpotomy associated with good adaptive healing response. During the past several years, special attention has been paid to Mineral Trioxide Aggregate -MTA as probable altern...
