The prevalence of pulpal involvement in young permanent teeth ranges between 0.3-36%. The outcome of Endodontic Therapy (ET) has not been widely studied in children and adolescents. Published studies that evaluated Endodontically Treated Teeth (ETT) in children and adolescents had results that varied tremendously. This variation could be due to the wide age range spanning from 6-18 years. Evaluating the predictors of survival, failure, and tooth retention between smaller subgroups within this age range may be relevant. AIM: To identify and assess variables associated with the outcome of ETT in 6-18 year old subjects stratified by age and to compare the results to the general population. METHODS: Retrospective chart review along with clinical follow up of subjects that received ET at BUGSDM between 2007-2015 at age 6-18 years. RESULTS: ET of the young permanent tooth resulted in 85% tooth survival and 91% retention. Patient age and tooth type were significantly related to survival and retention of ETT. CONCLUSIONS: Survival and retention of ETT observed among children and adolescents were similar to observations in adults. ET is more likely to survive when it is performed at an older age (15-18 years), or on an anterior tooth. This suggests that the longer ET is prevented through proper oral hygiene measures and preventive dental care, the better the likelihood of survival and retention of ETT in young patients.

Magister Scientiae Dentium - MSc(Dent) / Many books, articles and reviews of this aspect of restorative dentistry have been published. An attempt has been made to correlate all the relevant material in order that a comprehensive review of most of the published literature could be presented under one cover. It is possible that certain aspects have been omitted, this would not have been deliberate but in a review of this nature every published article may not have been attainable.

No sentido de colaborar com o estudo da redução de microrganismos em Endodontia, foi realizada uma análise crítica dos modelos metodológicos in vivo sobre as técnicas moleculares utilizadas na avaliação da microbiota endodôntica e na capacidade de medir a antissepsia que o tratamento endodôntico proporciona. Desta maneira, os trabalhos foram agrupados de acordo com a proposta do presente estudo. Na análise critica e comparativa, pode-se observar uma grande variedade de métodos moleculares aplicados nos estudos, sendo que o mais utilizado nos ensaios para avaliação da microbiota foi o PCR. Havia estudos que utilizavam uma combinação de vários métodos onde foi possível identificar microrganismos ainda não conhecidos. Nos ensaios que utilizam iniciadores universais e que se valem da identificação de microrganismos através do DNA, foram listados de maneira a poder observar que o iniciador universal formado pela seguinte cadeia de oligonucleotídeos: F: 5- AGA GTT TGA TCC TGG CTC AG-3/R: 5-ACG GCT ACC TTG TTA CGA CTT-3 foi o mais descrito pela literatura. / In order to collaborate with the study of disinfection in Endodontics, was performed a study of critical methodological models in vivo on the molecular techniques used in the evaluation of endodontic microbiota and the ability to measure the disinfection capacity of endodontic treatment. Thus, the studies were grouped according to the purpose of this study. Under in critical and comparative analysis its can be seen a wide variety of molecular techniques used in the studies, and as used in the tests was to evaluate the microbial PCR studies using a combination of various methods which could be identified microorganisms has not known. In assays using universal primers which rely on the identification of microorganisms using the DNA, were listed as to be able to observe that the universal primer chain formed by the following primers: F: 5\'-AGA GTT TGA TCC TGG CTC AG-3 \'/ R: 5\'-ACG GCT ACC TTG TTA CGA CTT-3\' was as described in the literature.
