Background: The primary objective of this study was to assess the occurrence, distribution, and features ectopic first permanent molars (FPMs), as well investigate clinical outcomes associated with eruption based on degree root resorption observed in second molars. Methods: This performed retrospectively by examining panoramic radiographs 7070 patients aged 5 12 years. gender age patients, numb...

Early detection of occlusal caries in children is challenging for the dentists, because of the morphology of pit and fissures. The aim of this study was to compare in vitro the diagnostic performance of low-powered magnification with light-emitting diode headlight (LPMLED) using ICDAS-II criteria and AC Impedance Spectroscopy (ACIS) device, on occlusal surfaces of primary molars. The occlusal s...

background: root canal cleaning is an important step in endodontic therapy. in order to develop better techniques, a new generation of endodontic instruments has been designed. the aim of this study was to compare the effectiveness of manual k-files (mani co, tokyo, japan) and two rotary systems–mtwo (dentsply-maillefer, ballaigues, switzerland) and protaper (vdw, munich, germany)–for root cana...

PURPOSE The aim of this pilot study was to assess the clinical performance of esthetic crowns and to compare these to conventional stainless steel crowns (SSC). METHODS Twenty two crowns (11 conventional and 11 esthetic) were placed in mandibular primary molars obeying the following criteria: the tooth was not mobile; no fistulae were present; the tooth had at least one caries free or properl...

INTRODUCTION Furcal perforations are one of the most challenging causes of endodontic failures. Several materials including MTA have been used for non surgical repair of these perforations. The aim of this study was to compare treatment outcome of furcal perforation treatment in primary molars using Root MTA and ProRoot MTA. MATERIALS AND METHODS This in vitro study was conducted on 54 primar...

INTRODUCTION Adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. This in vitro study evaluated the sealing ability of mineral trioxide aggregate (MTA), calcium-enriched mixture (CEM) cement and Biodentine in repair of furcation perforation in primary molars. METHODS AND MATERIALS A total of 61 freshly extracted primary ma...

AIM Proper anesthesia and pain management during treatment are most important concerns in dentistry for people of all ages, especially children. This study compared the success rate of lidocaine block with articaine buccal infiltration during anesthesia of the primary mandibular second molars in children aged 6 to 8 and 8 to 10 years. MATERIALS AND METHODS The present clinical trial was condu...
