Introduction: Relationship between periodontal infection and pulp pathosis has been debated for many years. This human case control study was performed to evaluate the possible effects of moderate to advanced chronic periodontitis on pulp stone formation and pulpal calcifications. Methods: Current study is an experimental case control study.  Samples included 23 hopeless permanent teeth...

Introduction & Objective: Preparation of access cavity to root canal is a critical phase in endo-dontic treatment. The purpose of this study was to evaluate the effect of access cavity loca-tion (labial or palatal) on fracture resistance of endodontically treated maxillary central teeth. Materials & Methods: In this experimental laboratorial study, 84 intact human maxillary central incisors w...

Aim: the aim of this study was to compare cusp deflection, infraction and fracture in teeth filled with three temporary filling materials. Materials & method: Forty five extracted human premolar teeth were chosen. After root canal therapy and mesio-occluso-distal cavity preparation, samples were randomly divided into three groups , each contained 15 teeth and filled with three temporary filling...

Introduction: This study aimed to evaluate and compare the apical sealing ability of different irrigation regimens (NaOCl, CHX, NS, and MTAD) . Methods: Seventy intact extracted single-rooted human teeth were selected. The roots were resected at 3 mm short of the apical foramen after access preparation. The canals were prepared with profile. This rotary file moved forward into the apical for...

  Objective: The diagnosis of vertical root fracture (VRF) in endodontically treated teeth is a clinical challenge due to lack of specific clinical and radiographic signs. Although radiographic evaluation such as CBCT is helpful, intracanal posts can produce artifacts and may impair the quality of CBCT scans. This study aimed to compare the diagnostic accuracy of different resolutions of CBCT i...

Objectives: In restorative dentistry, it is essential to estimate the amount of remnant tooth structure after caries removal to make the best treatment plan. The present study was aimed to determine whether there is a correlation between the real thickness of remnant dentin under carious lesion and the radiographical measurement from photostimulable phosphor plates (PSPs). Methods: a whole numb...
