Postoperative Pain after Endodontic Treatment under Irrigation with 8.25% Sodium Hypochlorite and Other Solutions: A Randomized Clinical Trial.

INTRODUCTION: The aim of this study was to evaluate the postoperative pain in patients after endodontic treatment using 8.25% sodium hypochlorite (NaOCl) compared with other concentrations and 2% chlorhexidine (CHX). METHODS: In this double-blind randomized trial, 180 patients were evaluated who underwent a single session of endodontic treatment under irrigation with 2.5%, 5.25%, or 8.25% NaOCl or 2% CHX solutions. The presence of postoperative pain was assessed 24, 48, and 72 hours after treatment and recorded using the visual analog scale (VAS). A descriptive analysis, logistic regression, and Wald test were performed. RESULTS: Altogether 169 patients participated, of whom 107 were women, and the mean age was 38.1 ± 14.4 years. No significant differences occurred between the irrigants and the pain outcomes, not even for the use of postoperative pain medication and responses to VAS (P > .05). In the multivariate model including irrigants, after 24 hours or at any time, a significant difference (P < .05) remained in preparation time ≥10 minutes and the presence of overfilling. Also, in relation to the VAS, the overfilling presented significantly different results (P < .05). CONCLUSIONS: There was no significant difference in the presence of postoperative pain between the 8.25% NaOCl and the other irrigation solutions. However, the extended preparation time and the overfilling material were responsible for the increase of postoperative pain.

Avaliação de métodos de manutenção da esterilidade do órgão dental humano extraído para armazenamento em banco de dentes / Evaluation of methods for maintaining sterility of the extracted human dental organ during storage in a tooth bank

A importância de um banco de dentes humanos em uma instituição de se justifica e se mostra vantajosa, uma vez que permite a máxima aproximação da realidade ao se trabalhar com o órgão extraído. Este estudo teve o propósito de avaliar métodos de manutenção da esterilidade do órgão dental humano extraído armazenado. Foram utilizados 72 dentes incisivos humanos extraídos, obtidos em clínicas de graduação e de pós-graduação da Universidade Positivo, Curitiba, PR, Brasil. Os elementos dentários foram cedidos pelos pacientes, por meio de termo de doação devidamente assinado. Após os procedimentos de limpeza e de desinfecção, 36 dentes foram esterilizados em autoclave e 36 foram somente limpos. Os dentes foram, então, armazenados em recipientes contendo o método (autoclavagem ou limpeza) ou a solução de escolha, por um período de 15 e 120 dias. Testes microbiológicos foram realizados a fim de determinar qual método ou solução de armazenamento promove a manutenção da esterilidade no tempo determinado. Melhores desempenhos foram observados quando as amostras foram armazenadas em Incidin Extra N®, formol e álcool, mesmo para os dentes não autoclavados. As substâncias em análise nos períodos propostos se mostraram capazes de impedir o crescimento microbiano. Este experimento poderá auxiliar o desenvolvimento de um protocolo de processamento e de administração do órgão dental humano extraído em um banco de dentes (AU).

The importance of a human teeth bank in an institution is justified and it is advantageous, since it allows the maximum approximation of reality when working with the extracted organ. This study aimed to evaluate methods for maintaining the sterility of extracted human teeth during storage. A total of 72 human incisors extracted in the undergraduate and graduate clinics of Universidade Positivo (Curitiba, PR, Brazil) were used in this study. The teeth were provided by patients, who signed a donation form. After all teeth were subjected to cleaning and disinfection procedures, 36 teeth were autoclaved as well. Teeth were then stored in various solutions for periods of 15 and 120 days. Microbiological tests were conducted to determine which method or storage promoted maintenance of sterility. Better results were obtained for teeth - including autoclaved teeth - stored in Incidin Extra N®, formaldehyde, and alcohol. The solutions analyzed over the proposed time periods have been shown to prevent microbial growth. Results of this study will aid in developing a protocol of processing for extracted human dental teeth to be stored in a tooth bank (AU).

Epidemiological data and relevance of care provided in dental emergency service of a private hospital

Introduction and Objective: The aims of this study were to determine the etiology and prevalence of dental emergency visits in a private hospital in the period from July 2009 to July 2011 and the importance of this type of service in private hospitals. Material and methods: During the study period, we analyzed 795 charts from patients seeking emergency services. The emergencies were classified as trauma, odontalgia, prosthesis, periodontal diseases, and traumatic factors. Results: Women and men accounted for 61% and 39% of cases, respectively, and the most prevalent age group was individuals aged 20 to 49 years. The predominant types of dental emergencies observed were odontalgia (52.58%) and dental trauma (22.64%). Pulpitis was the most common pathology (67% of cases) and the most frequent type of trauma was enamel and dentin fracture (54% of cases). Conclusion: A high demand for dental emergency care exists in hospital settings. Most people seek emergency dental services for emergencies related to lack of prevention and dental traumas.

Knowledge of triathlon athletes about the relationship between oral health and performance

Introduction: The triathlon athletes have great energy loss due to physical activity of high intensity and resets are based on a highcarbohydrate diet and acid elements (acids replacers), both substrates to decay and periodontal disease. Objective: This study aimed to evaluate, through a questionnaire whether triathlon athletes relate oral health to their physical performance. Material and methods: We developed a questionnaire with 20 objective questions and applied during marathons and at fitness centers, in the city of Curitiba, in 2015. Results: The majority of athletes use supplements with high levels of carbohydrates and acids for energy replacement daily and do not brush their teeth after workouts / nutrition. Of the 254 respondents, only 96 relate oral health to their performance in sports. Conclusion: The athletes do not relate the importance of oral health care to performance and largely do not brush the teeth after the activities, leaving the oral environment more susceptible to the onset of periodontal disease and caries, which can decrease their performance. It is necessary to inform triathlon athletes about the relationship oral health x systemic health x performance, as well as the dentists about the need of oral health care for these athletes.
