INTRODUCTION Knowledge of the anatomic location and dimension of the molar pulp chamber may preserve healthy pulp during operative procedure and reduce risk of perforation of chamber during access preparation. A review of literatures regarding the morphology of pulp chamber however revealed very little information; so the aim of this in vivo study was to measure the dimensions of first molar pu...

Aim: The study aims to compare the use of clinical probing and Cone Beam Computed Tomography (CBCT) in diagnosis furcation involvement (FI) patients with periodontitis. Methods materials: Twenty-two patients, aged 30 65 years periodontitis were included study. who visited from April 2021 May 2022 assessed based on selection criteria. A total 135 teeth checked for involvement. Buccal, mesiopalat...

Background– Periodontal disease, if not interfered, will headway further with attachment loss involving the bifurcation or trifurcation of multirooted teeth. Furcation involved molar teeth respond less favorably to conventional periodontal therapy alone resulting into tooth loss. Combining osseous grafting guided tissue regeneration membrane may enhance response treatment as compared graft – on...

background: congenital heart disease (chd) is the most common congenital anomaly in newborns. this study was performed to determine the live birth incidence of chd by ethnicity and sex in gorgan, northern iran. methods: in this longitudinal, hospital-based study, 18162 live births in dezyani hospital in gorgan, north of iran, were screened for chd, from 2007 through 2009. clinical examination, ...

background: closure of patent ductus arteriosus (pda), ventricular septal defect (vsd) and atrial septal defect (asd) can be done surgically or by device. this study was designed to compare the total cost of surgical or device closures of pda, asd or vsd for iranian patients. methods: this is a cross-sectional study, conducted from january 1, 2005 until january 1, 2006 in two large heart center...

this is a case presentation of a 26-year-old woman with a moderate-sized atrial septal secundum defect (17mm) who underwent catheterism, during which an amplatzer septal occluder number 26 was inserted successfully. on the second postoperative day, she deteriorated and a clinical examination showed a typical tamponade. after a percutaneous aspiration of the pericardial cavity and transient impr...

We report a patient with severe chronic periodontitis requiring regenerative periodontal surgery and different types of prosthesis in the maxillary and mandibular regions. The patient was a 57-year-old woman who presented with the chief complaint of occlusal pain. An initial clinical examination revealed that 73% of sites had a probing depth of ≥4 mm, and 60% of sites exhibiting bleeding on pro...

BACKGROUND Regenerative periodontal therapy aims to predictably restore the tooth's supporting periodontal tissues and should result in formation of a new connective tissue attachment (i.e. new cementum with inserting periodontal ligament fibres) and new alveolar bone. Histologic evidence from preclinical models has demonstrated periodontal regeneration following treatment with barrier membrane...
