The aim of this study was to evaluate the influence of calcium chloride (CaCl(2)) on the sealing ability of three Mineral Trioxide Aggregate (MTA) cements, ProRoot MTA, MTA-Angelus, and radiopaque White Portland cement (WPC), for retrograde root filling. Seventy roots of extracted single-rooted teeth were instrumented and obturated. After sectioning the samples at 2 mm from the apex, they recei...

Purpose: To evaluate the ability of BiodentineTM as a retrograde root-end filling in conjunction with a well-documented periapical surgery protocol in a clinical case series study. Material and Methods: Thirteen teeth in 13 patients referred for periapical surgery were included in the study. Teeth with obvious signs of root-fracture or apical-marginal communications were excluded from the study...

AIM This randomized, controlled, clinical study was designed to evaluate the adjunctive effect of calcium sulphate grafts on the surgical treatment of through and through periradicular lesions. METHODOLOGY Twenty patients each with one tooth showing evidence radiologically of a periradicular lesion wider than 10 mm, with lack of both buccal and lingual cortical bony plates and an indication f...

AIM Dentists are probably contributing to the development of bacterial resistance to certain antibiotics. Campaigns to promote prudent use of antibiotics in dentistry are, thus, needed but require proper identification of dentists' knowledge gaps. The objective here was to comprehensively evaluate antibiotic prescription knowledge of dentists in Saudi Arabia. MATERIAL AND METHODS A link to an...

CASE REPORT This case report describes the outcome of a number of retreatments on a failed root filling in a maxillary first molar. The patient wanted all amalgams replaced by tooth-coloured Cerec restorations, including one in a symptomless maxillary molar. This tooth had a pulpotomy or a poorly done root-canal treatment 10 years earlier. The molar was root-canal retreated before placing the C...

INTRODUCTION Procedural accidents have a negative effect on healing and might contribute to the persistence of infections in inaccessible apical areas, requiring surgical intervention. This report describes a case of persistent apical periodontitis of a lower left first molar associated with the sinus tract and a periapical lesion that required nonsurgical endodontic retreatment and apical surg...

as gray-yellowish necrotic material. Necrotic material is not observed in an intact cystic lesion, such as a dentigerous cyst. This material was probably keratin, which is not produced in dentigerous cysts 3. Although the diagnosis is established solely after histo-pathological analysis, some imaging features presented in this case are more likely to indicate OKC. Radiolucencies distal to the t...

PURPOSE The aim of this study was to answer the question: For patients requiring apicoectomy (apicectomy/root-end resection) and retrograde (root-end) obturation (filling), which retrograde obturation (root-end filling) material(s) is/are the most effective, as determined by reduction in periapical radiolucency and elimination of signs and symptoms? MATERIALS AND METHODS A MEDLINE and a Cochr...

BACKGROUND AND AIM: A periapical endodontic surgery is an alternative treatment when teeth are not responding to conventional treatment and endodontic re-treatment.CASE REPORT: The following case report presents a clinical case of maxillary right and left central incisors with unsatisfying endodontic surgery and severe sensitivity in the buccal mucous membrane. Radiographic examination revealed...
