In recent years, periapical surgery has evolved thanks to new diagnostic and technical advances. A review is made of the literature on periapical surgery of the antral teeth, based on a Medline search and on the revision of Spanish dental journals in the period between 1974 and 2003. The anatomy of the maxillary sinus is discussed, along with the diagnosis of periapical lesions and the relation...

The aim of this study was to evaluate the accuracy of imaging methods for detection of apical periodontitis (AP). Imaging records from a consecutive sample of 888 imaging exams of patients with endodontic infection (1508 teeth), including cone beam computed tomography (CBCT) and panoramic and periapical radiographs, were selected. Sensitivity, specificity, predictive values, and accuracy of per...

The pathogenesis of periapical lesions has not been fully elucidated. Currently, the possibility of its being an immunologic phenomenon is receiving much attention. This article presents a review of the literature concerning immunologic reactions which may involve periapical lesions. It appears that antigen-antibody complexes and IgE-mediated reactions can initiate preliminary changes in periap...

BACKGROUND Jaw bones might be potential locations for different lesions. Differences in prevalence and the type of lesions can help in designing and programming prevention procedures in health care centers. OBJECTIVES The aim of the present study was to evaluate the prevalence of intraosseous lesions in the jaws of patients referred to diagnostic and therapeutic centers in Hamadan during 1990...

Nine hundred fifty-one emergency and 997 nonemergency patients seeking endodontic treatment were the basis of this study. Variables of interest were 10 pain descriptors, percussion and palpation tests, causative factors, and paired pulpal and periapical diagnoses. A higher number of patients suffering from symptomatic pulpal conditions sought emergency care. Odds of caries being a causative fac...

BACKGROUND The prevalence of apical periodontitis in diabetes mellitus patients is high. The altered immunity in diabetes affects the healing process of periapical tissue. Single visit endodontic treatment has shown to increase the periapical healing rate with better patient compliance. Hence the present study aims at evaluating the clinical and radiographic healing outcome of single visit endo...

PURPOSE The purpose of this study was to evaluate the success of dental implants placed immediately into extraction sites in the presence of chronic periapical pathology. MATERIALS AND METHODS The charts of 655 patients who had implants immediately placed into fresh extraction sites were reviewed for the presence or absence of periapical radiolucencies. A total of 922 implants were included. ...

Periapical cyst is a chronic inflammatory disorder of periradicular tissues. The precise pathological mechanisms involved in periapical cyst enlargement remain unclear. Notch signaling is an evolutionarily conserved pathway with a regulatory role in cell fate decisions during development and in carcinogenesis. To date, there are no published data available on the expression of Notch signaling c...

Granuloma annulare is a benign, relatively common dermatosis of childhood and young adults. Lesions typically occur on the extremities. Localized facial and periocular involvement is rare. We describe a 25- year-old woman with asymptomatic skin-color, firm, and papular lesions on both periocular areas since 6 months ago. Histological examination revealed palisading necrobiotic granuloma, charac...

INTRODUCTION Intermittent administration of parathyroid hormone (PTH) promotes oral osseous wound healing and protects against ligature-induced alveolar bone loss. However, its therapeutic value on periapical periodontitis is unknown. The goal of this study was to determine the effect of intermittent PTH administration on the progression of periapical periodontitis. METHODS Seven lymphotoxin ...
