INTRODUCTION This study evaluated the in vivo response of apical and periapical tissues of dogs' teeth with apical periodontitis after one-session endodontic treatment with and without antimicrobial photodynamic therapy (aPDT). METHODS Sixty root canals with experimentally induced apical periodontitis were instrumented and assigned to 4 groups receiving(More)
This case report describes a case of intrusion of the right mature permanent central incisor. After gingivectomy and endodontic treatment with changes of the intracanal dressing (calcium hydroxide paste) every 30 days, spontaneous re-eruption was observed. We conclude that waiting for spontaneous re-eruption associated with gingivectomy and endodontic(More)
AIM To evaluate ex vivo the accuracy of two electronic apex locators during root canal length determination in primary incisor and molar teeth with different stages of physiological root resorption. METHODOLOGY One calibrated examiner determined the root canal length in 17 primary incisors and 16 primary molars (total of 57 root canals) with different(More)
This study was evaluated the response of subcutaneous connective tissue of isogenic mice to calcium hydroxide-based pastes with chlorhexidine digluconate (CHX). Seventy isogenic male BALB/c mice aged 6-8 weeks and weighing 15-20 g were randomly assigned to 8 groups. The animals received polyethylene tube implants as follows: Groups I, II, and III (n=10) -(More)
INTRODUCTION This study evaluated the pulpal and periapical responses of dogs' teeth after pulpotomy and pulp capping with a new tricalcium silicate-based cement (Biodentine) when compared with mineral trioxide aggregate (MTA) by radiographic, histopathologic, and histomicrobiological analyses. METHODS Sixty roots (30 teeth) of dogs were divided into 2(More)
This study evaluated the response of the subcutaneous connective tissue of BALB/c mice to root filling materials indicated for primary teeth: zinc oxide/eugenol cement (ZOE), Calen paste thickened with zinc oxide (Calen/ZO) and Sealapex sealer. The mice (n=102) received polyethylene tube implants with the materials, thereby forming 11 groups, as follows: I,(More)
OBJECTIVE This study evaluated the response of apical and periapical tissues of dogs' teeth with pulp vitality after root canal filling with the endodontic sealers Sealapex Xpress and Real Seal XT. METHODS Thirty-eight root canals with vital pulp from dogs' premolars were used. After instrumentation, the canals were filled with Sealapex Xpress and(More)
Few studies are available about racial inequalities in perinatal health in Brazil and little is known about whether the existing inequality is due to socioeconomic factors or to racial discrimination per se. Data regarding the Ribeirão Preto birth cohort, Brazil, whose mothers were interviewed from June 1, 1978 to May 31, 1979 were used to answer these(More)
OBJECTIVE To verify the concordance between data routinely collected by the Sinasc (Information System on Live Births) and data obtained by a cross-sectional survey (gold standard). METHODS The survey was performed in a sample of 2,831 hospital deliveries in ten maternity hospitals of the municipality of São Luís, Brazil. The sample frame represented(More)
Lymphangiomas are benign tumors resulting from a congenital malformation of the lymphatic system. Relatively uncommon, lymphangiomas are usually diagnosed at birth and develop within the first years of life. When these tumors occur in the oral cavity, the tongue is the most frequently affected site. Lymphangioma of the tongue is a common cause of(More)
