introduction: this cross-sectional survey determined the dental prevalence of apical periodontitis (ap) in selected iranian population, and evaluated the influence of the quality of root canal treatment (rct) and their coronal restorations (cr) on the periapical status. materials and methods: a total of 1064 panoramic radiographies were evaluated by two observers during 2009. the quality of rct...

BACKGROUND Traumatic injuries of permanent teeth with incomplete root formation are frequent during childhood. Adequate therapy is important for the further destiny of teeth with damaged pulp. OBJECTIVES To evaluate the effect of pulpotomy and high pulpotomy on the pulp and on root development, and the effect of platelet rich plasma (PRP) with hydroxyapatite (HAP) as a carrier and hydroxyapat...

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...

INTRODUCTION Root canal-treated teeth are weaker than vital teeth and are more susceptible to fractures. Therefore, special precautions should be adhered to, such as the use of various types of cast or prefabricated posts. Regarding the effect of post material on fracture resistance of teeth, the aim of this in vitro study was to evaluate the effect of non-precious gold color alloy (NPG) and ni...

This study investigated the prevalence of apical periodontitis (AP) and its association with endodontically treated teeth in residents of São Luís, MA, Brazil. Two-hundred complete series of periapical radiographs taken over a 10-year period (1993-2003) were retrieved from the files of four prosthesists and five periodontists. The Periapical Index (PAI) was used and the age range, sex, tooth gr...

introduction: in cases of severe hard tissue loss, 2 mm circumferential ferrule is difficult to achieve. so in these cases we should use different ferrule designs. this in vitro study investigated the effect of different ferrule designs on the fracture resistance of teeth restored with bonded post and cores. materials and methods: forty freshly-extracted central incisors were endodontically tre...

the :union: of two different dental sprouts which can happen in any phase of dental development is commonly called fusion. this developmental anomaly may cause clinical problems including esthetic impairment, which are mainly treated by endodontic and surgical treatments. there are a few reports of conservative not invasive treatment of fused incisors teeth through restorative or prosthetic tec...

The goal of this general article is to present a survey of the current knowledge about the clinical approach of restoring endodontically treated teeth. The best way to restore teeth after root canal treatment has long been and still is a controversial subject of debate to this day. The clinical approach of restoring endodontically treated teeth needs taking into consideration several issues: ai...

Introduction: The restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. The aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. Methods: E...
