A previous study by our group found nickel-titanium (NiTi) 0.02 hand files maintained the original canal shape better than similar stainless-steel K-files (SS-K). Inexperienced dental students used both file types on molar teeth. The purpose of this study was to compare the 1-yr success rate of endodontic treatment of the same teeth used in our previous(More)
Volume 28, Number 2, June 2002 With the rapid spread of HIV throughout Sub-Saharan Africa, new approaches to HIV prevention are urgently needed, especially among young women. Family planning services have traditionally focused on promoting methods that are highly effective at preventing pregnancy but provide no protection against HIV. Further, thousands of(More)
This study was performed to evaluate radiographic healing of teeth with apical periodontitis, treated in one visit or in two visits (a) with or (b) without calcium hydroxide as an intracanal disinfecting medicament. The patients were assigned one of the three treatment groups by the throwing of a die. The Periapical Index (PAI) Scoring Method was used to(More)
BACKGROUND Extraction and endodontic therapy are treatment options for irreversible pulpitis. Extraction often is chosen for financial reasons. The authors conducted a study to investigate an alternative interim therapy. METHODS The authors recruited patients (N = 73) with irreversible pulpitis and whose teeth were restorable but who opted for extraction(More)
Increased levels of systemic inflammatory markers have been observed in patients with chronic dental diseases, such as marginal periodontitis. A canine model was used to determine if a systemic inflammatory response was evident during chronic apical periodontitis (CAP). Dental pulps in 10 dogs were exposed and infected with dental plaque to induce CAP.(More)
PURPOSE This prospective clinical study was designed to determine the clinical and biologic outcomes of treatment for minor signs and symptoms of pericoronitis. PATIENTS AND METHODS Patients (n = 20) with all third molars, presenting consecutively to an academic clinical center for treatment of minor signs and symptoms of pericoronitis, were enrolled in(More)
OBJECTIVE The purpose of this study was to compare both subjective (Periapical Index, PAI) and objective (densitometric) radiographic evaluation of healing after endodontic treatment for apical periodontitis. STUDY DESIGN Standardized radiographs of 103 teeth taken at baseline (immediately after endodontic treatment) and at 1, 4, 12, 26, and 52 weeks were(More)
The objective of this study was to establish an objective method for evaluating the treatment outcome of apical periodontitis (AP). AP was induced in the mandibular premolars of beagle dogs and apicoectomies were performed with retrofilling. Standardized periapical radiographs were taken immediately after completion of treatment and at 6 months. Ten pairs(More)
This study compares the diagnostic accuracy of caries detection using Ultra-speed (Eastman Kodak), Ektaspeed (Eastman Kodak) and Ektaspeed Plus (Eastman Kodak) films after they were developed in both new and used processing solutions. Ektaspeed Plus film provided significantly better diagnostic accuracy for small proximal-surface caries limited to the outer(More)
