although the delayed exfoliation of primary teeth among children is a common dental problem, simultaneous presence of primary teeth and corresponding successors is a rare feature in adults. this paper reports an unusual case in which both permanent teeth (molars, premolars, and canines) and primary teeth were present simultaneously. this report describes questions concerning the etiology of ove...
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...
Introduction: Premature loss of primary teeth affects child's nutrition, sleep, growth, and self-confidence. Besides, it can cause undesirable movement of the primary or permanent teeth. Case presentation: This paper reports a 5.5-year old boy presenting with severe-early childhood caries, who had suffered from early extraction of some primary teeth as well as several other dental problems. Af...
Background and Aim: Although the use of adhesive systems can be effective in decreasing microleakge, it is still a major problem in composite resin restorations. The aim of the present study was to evaluate the marginal sealing ability of resin composite restorations using four dentin bonding systems in both primary and permanent teeth. Materials and Methods: In this experimental study, one hun...
Abstract Introduction: This study aimed to determine the prevalence of dental caries and plaque in patients undergoing removable orthodontic treatment. Materials and Methods: In this cross-sectional study, 57 patients were selected and examined for dental caries (clinically and radiographically) and plaque (O’Leary Index) on permanent and primary teeth. Data were analyzed using chi-square an...
Odontomas are benign tumors of odontogenic origin characterized by their slow growth. They are considered to be a common type of odontogenic tumor, but rarely occur in the primary dentition.The etiology of odontomas is unknown, although local trauma, infection and genetic factors have been suggested. Odontomas often cause disturbances in the eruption of teeth such as, impaction or delayed erupt...
introduction: ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. but the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide eugenol paste. the aim of this study was to determine and compare ...
Background and Aim: Restoration of primary anterior teeth with severe caries extending to the gingival margin is challenging for many clinicians especially in uncooperative children. Resin modified glass ionomer cements (RMGICs) can be suitable for use in such cases since they require fewer application steps than composite resins. This study aimed to assess the fracture strength of severely dam...
