The objective of this study was to evaluate the bacterial profile in root canals of human primary teeth with necrotic pulp and periapical lesions using bacterial culture. A total of 20 primary teeth with necrotic pulp and radiographically visible radiolucent areas in the region of the bone furcation and/or the periapical region were selected. After crown(More)
INTRODUCTION This randomized clinical trial assessed, by using microbial culture and scanning electron microscopy (SEM), the contamination by mutans streptococci (MS) colonies/biofilms on acrylic baseplates of removable orthodontic appliances and evaluated the efficacy of antimicrobial sprays (Periogard [Colgate-Palmolive Ind. Brasileira, Osasco, SP,(More)
This report describes a case of a patient (1 year and 8 months old) with traumatic avulsion of the maxillary right primary central incisor and morphological changes in the germ of the permanent successor. One year after the trauma, an odontoma-like malformation developed. This malformation was removed 6 years after trauma and orthodontic treatment was(More)
The aim of the present study was to evaluate the effect of calcium hydroxide dressing on the bond strength of three commercially available endodontic sealers (MTA Fillapex, Sealapex, and AH Plus) to root canal dentin. Sixty slices of extracted human canines were obtained from cervical, middle, and apical root thirds. Root canals were standardized and(More)
PURPOSE The purpose of this study was to evaluate mouth-breathing and nasal-breathing children prior to surgical intervention and 28 months postoperatively, comparing the occlusal features obtained pre- and postoperatively through orthodontic study casts. METHODS The mouth-breathing (MB) group consists of 33 MB children who underwent surgery and(More)
BACKGROUND Morphological and dentofacial alterations have been attributed to impaired respiratory function. OBJECTIVE To examine the influence of mouth breathing (MB) on children facial morphology before and after adenoidectomy or adenotonsillectomy. METHODS Thirty-three MB children who restored nasal breathing (NB) after surgery and 22 NB children were(More)
PURPOSE The purpose of this study was to evaluate: (1) in vivo the contamination by mutans streptococci (MS) of toothbrushes after use on 52 children (24-48 months old) by a single dentist; (2) in vivo the efficacy of 3 solutions (Periogard, Brushtox, and a Cosmocil CQa and Myacide pharma BPa-based experimental solution) in the disinfection of these(More)
Chlorhexidine (CHX), widely used as antiseptic and therapeutic agent in medicine and dentistry, has a toxic effect both in vivo and in vitro. The intrinsic mechanism underlying CHX-induced cytotoxicity in eukaryotic cells is, however, still unknown. A recent study from our laboratory has suggested that CHX may induce death in cultured L929 fibroblasts via(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)
This report describes the case of a 10-year-old boy that was referred to the pediatric dentistry clinic 15 days after sustaining a severe traumatism that led to complete intrusion of the maxillary left mature permanent central incisor. The intruded tooth was repositioned by using surgical extrusion. Endodontic therapy was performed with calcium(More)
