OBJECTIVES To assess the prevalence of both impaction and associated pathosis in a Saudi population in Al-Madinah, Saudi Arabia based on digital panoramic radiographs. METHODS This study was carried out from December 2013 to February 2015. Panoramic radiographs of 359male patients attending the Oral Diagnosis Clinics, Faculty of Dentistry, Taibah University, Al-Madinah, Saudi Arabia were revi...

Eleven unrestorable primary molars with interradicular radiolucencies were extracted. The granulation tissue was curretted from the sockets and examined using immunofluorescence for the immunoglobulins IgG, lgA, and IgM, and the third component of complement. The results demonstrated the presence of IgG in 100%, C3 in 80%, Ig~ in 54.5%, and IgM in 18.1% of the lesions. In an attempt to describe...

PURPOSE To compare ferric sulfate (FS) pulpotomy and primary tooth root canal therapy (RCT) in cariously exposed vital pulps of primary incisors. METHODS A total of 133 incisors in 50 children were randomly selected to be treated by FS pulpotomy (64) or RCT (69). RESULTS Two years after treatment, 77 incisors (41 FS pulpotomy, 36 RCT) were available for clinical and radiographic examination...

Objectives: The aim of this study was to investigate levels of matrix metalloproteinase-8 (MMP-8) and substance P (SP) in root canal exudates during root canal treatment (RCT) of nonvital, painful teeth. Materials and Methods: Patients scheduled for nonsurgical RCT were prospectively selected; the study was performed after obtaining informed consent from the patients and was approved by the Ins...

Calcium hydroxide is advocated as an intracanal medication for various purposes, including prevention of posttreatment symptoms. This study assessed whether calcium hydroxide had a pain-controlling effect at different times when compared with no intracanal medication. One hundred forty patients participated. Conditions diagnosed were pulp/periapical pathosis with or without symptoms. At least p...

INTRODUCTION There is a lack of research to support the belief that root canal treatment can be considered for stopping or decreasing external apical root resorption (EARR). There is conflicting evidence as to whether root-filled teeth are more or less likely to experience EARR after orthodontic treatment. The purpose of this study was to compare the degree of EARR of root-filled teeth with tha...

Surgical endodontics was performed using an Er:YAG laser on 23 patients (4 males, 19 females) exhibiting periapical pathosis. After mucoperiosteal flap reflection, osteotomy was performed over the lesion using a low-speed dental engine with a round bur (#6–8). Root-end resection was then performed using an Er:YAG laser (100 mJ, 10 pps) with copious saline coolant. The root apex cavity for the r...
