Efficacy of various intracanal medicaments against aerobic and facultative anaerobic microorganism found in human primary teeth with necrotic pulp: A randomized clinical trial.

AIM: The aim of this in vivo study is to evaluate the antimicrobial efficacy of calcium hydroxide (Ca(OH)2), chlorhexidine (CHX), and metronidazole gel as intracanal medicaments against aerobic and facultative anaerobic microorganisms found in root canals of human primary teeth with necrotic pulp. SETTING AND DESIGN: It is a double-blinded randomized clinical trial. MATERIALS AND METHODS: Pulp canals of 45 single-rooted primary maxillary anterior teeth with pulp necrosis in 34 children were included in the study. They were divided into three groups of 15 samples each: Group I: Ca(OH)2; Group II: 1% CHX gel; and Group III: 1% metronidazole gel. Microbial count was obtained from each tooth at two different stages - (1) after instrumentation and (2) after placement of the medication. Statistical analysis using the SPSS 10.0 software program (SPSS Inc., Chicago, IL, USA) with Wilcoxon signed-rank test after grouping the samples was performed. RESULTS: Ca(OH)2, 1% CHX gel, and 1% metronidazole gel were ineffective in completely eliminating aerobic and facultative anaerobic microorganism from root canal of human primary teeth with necrotic pulp. CONCLUSION: None of the commonly used intracanal medicaments, that is Ca(OH)2, 1% CHX gel, and 1% metronidazole gel, was effective in completely eliminating aerobic and facultative anaerobic microorganism from root canal of human primary teeth with necrotic pulp. Ineffectiveness of these medicaments against aerobic and facultative anaerobic microorganism has opened new door of research regarding the manner of bacterial growth in unfavorable environmental and nutritional conditions, the way root canal environment favors biofilm formation and the use of suitable intracanal medicaments against single and multispecies biofilms.

Efficacy of Various Intracanal Medicaments in Human Primary Teeth with Necrotic Pulp against Candida Biofilms: An in vivo Study.

BACKGROUND: Candida has been associated with cases of secondary and persistent root canal infections. The purpose of this study was to evaluate and compare the effectiveness of commonly used intracanal medicament against Candida biofilms found in root canals of human primary teeth with necrotic pulp. MATERIALS AND METHODS: Pulp canals of 45 single-rooted primary maxillary anterior teeth with pulp necrosis in 34 children were included in the study. They were divided into three groups of 15 samples each - group I: Ca(OH)2 (calcium hydroxide); group II: 1% chlorhexidine gel (CHX); and group III: 1% metronidazole gel. Bacterial count was obtained from each tooth at two different stages: (1) after instrumentation, and (2) after placement of the medication. Statistical analysis using the Statistical Package for the Social Sciences version 10.0 software program (Inc., Chicago, IL, USA) with Wilcoxon signed rank test after grouping the samples was performed. RESULTS: Ca(OH)2, 1% CHX gel, and 1% metronidazole gel were ineffective in completely eliminating Candida biofilms from root canal of human primary teeth with necrotic pulp. CONCLUSION: None of the commonly used intracanal medicaments, i.e., Ca(OH)2, 1% CHX gel, and 1% metronidazole gel, was effective in completely eliminating Candida biofilm from root canal of human primary teeth with necrotic pulp. Ineffectiveness of these medicaments against Candida has opened new door of research regarding the use of suitable intracanal medicaments against single and multispecies biofilms.

Christ Siemens Touraine syndrome: A rare case report.

Christ-Siemens-Touraine (CST) is a rare hereditary disorder of X-linked recessive trait, characterized by abnormal development of two or more structures or tissues of ectodermal origin. The common clinical findings include hypodontia, hypohydrosis, hypotrichosis, and onychodysplasia. Although hypodontia is common, anodontia is a rare feature. Most of the patients are suffering from social rejection and consequent psychological trauma because of the facial dysmorphism and absence of multiple teeth. Oral rehabilitation is of prime importance for such patients. This article presents a case in a 5½-year-old boy presenting with altered manifestations affecting almost all the ectodermal structures like skin, hair, nails, teeth, sebaceous glands, sweat glands, salivary glands, mammary glands, and tear glands. He also had complete anodontia and dry mouth. A multidisciplinary treatment was given to the patient with the collaboration of various health professionals. The child gained confidence and was relieved from the psychological impact following the prosthetic rehabilitation.

Efficacy and tolerance of papain gel with conventional drilling method: a clinico-microbiological study.

BACKGROUND: Conventional methods of caries removal are commonly associated with pain, fear and discomfort. Chemomechanical methods were introduced to instill a positive dental attitude. Agents like GK-101, Caridex, Carisolv did not prove effective alternatives owing to their high cost, need of special instruments and taste of chlorine. A new chemomechanical agent, Papacarie®, has been introduced to overcome these deficiencies. OBJECTIVE: This study was aimed to compare the effectiveness and tolerance of Papacárie® with the conventional method. METHOD: 25 children with at least two primary teeth with broad cavitated occlusal or cervical lesion were selected. One carious tooth from each patient was randomly treated with each of Papacarie® and conventional drilling method, one after the other. Time taken for caries excavation, child's pain perception, change in anxiety levels, microbial flora and child's preference of treatment were recorded separately for both the methods. RESULT: Although the mean time taken for caries removal by the Papacarie® method was slightly longer (P≯0.05) but it led to reduction in pain and anxiety (p<0.05). The viable bacterial counts were significantly reduced by either of the two methods (P <0�0001). More patients preferred Papacarie® over conventional method of treatment (P<0.05). CONCLUSION: Papacárie® method seems to be a better alternative to conventional method of caries removal.

Apert syndrome.

Apert syndrome (acrocephalosyndactyly) is a rare developmental malformation characterized by craniosynostosis, mid-face hypoplasia, symmetrical syndactyly of hands and feet. The prodromal characteristics for the typical cranio-facial appearance are early craniosynostosis of the coronal suture, cranial base and agenesis of the sagittal suture. The purpose of this paper is to report a case of Apert syndrome with emphasis on craniofacial and oral features in an eighteen-month-old male child. The patient presented with several craniofacial deformities, including brachycephaly, midface hypoplasia, flat face, hypertelorism, ocular proptosis, downslanting palpebral fissures. Syndactylies with osseous fusion of the hands and feet were also observed. Intraoral findings included delayed eruption of teeth, high arched palate with pseudo cleft in the posterior one third.

Unicystic ameloblastoma of the maxilla: a case report.

Unicystic ameloblastoma is believed to be less aggressive and responds more favorably to conservative surgery than the solid or multicystic ameloblastomas. This report is a rare case of unicystic ameloblastoma of the maxilla that was treated by enucleation under suspicion of a radicular cyst related to a dens in dente. The neoplastic nature of the lesion became evident only when the enucleated material was available for histologic examination. With this report, the authors illustrate the importance and complexity of a differential diagnosis of lesions with a cystic aspect in the anterior region of the maxilla, among them - inflammatory radicular cysts, odontogenic keratocysts, adenomatoid odontogenic and unicystic ameloblastoma. Relevant diagnostic problems and choice of treatment of unicystic ameloblastoma are presented along with a review of the literature.
