ABSTRACT
Abstract Objective: To evaluate the factors associated with the occurrence of dental trauma in children up to six years of age and describe the results of clinical follow-up and possible sequelae. Material and Methods: A retrospective study was carried out with data collected from the dental records of 96 pediatric patients up to 6 years old with traumatized primary teeth who sought care from the. Pediatric Dental Trauma project of a private university in the city of Rio de Janeiro from July 2014 to July 2017, and who had clinical and radiographic follow-up for up to three months as of their initial visit. Results: 96 children (58.3% boys and 41.7% girls) included who presented 166 traumatized primary teeth. Intrusion was the most observed type of trauma and in 45.8% of cases, the care occurred one-week post trauma. The maxillary central incisors were the most affected teeth (97.6%). The prognosis of the dental elements with more than 3 months of follow-up was considered favorable, and 59.6% of the teeth did not present any clinical or radiological sequelae. Oral hygiene instruction and monitoring were the most common approaches. Conclusion: The prevalence of dental trauma in the present study was high and occurred mainly in domestic settings. The upper central incisors were the teeth that suffered the most injuries. The presence of patients at follow-up visits was an important factor for the positive result in most cases.

Os microrganismos têm um papel essencial na etiopatogenia das principais alterações pulpares e periapicais. O resultado da terapia endodôntica em dentes contendo polpa necrosada e infectada depende da desinfecção bem-sucedida e obturação adequada do sistema de canais radiculares. A eliminação de microrganismos pode ocorrer pela ação mecânica, associado à irrigação dos canais radiculares. No entanto, apesar dos recentes avanços em termos de técnicas e instrumentos de preparo, diversas áreas do canal ainda permanecem com detritos dentinários e micro-organismos mesmo após a instrumentação. Isto ocorre em grande parte devido à complexidade anatômica. Assim, o objetivo desta revisão de literatura é apresentar diferentes abordagens para suplementar a desinfecção dos canais radiculares, incluindo a irrigação ultrassônica passiva (IUP), a irrigação final com clorexidina, Endovac®, o sistema Self-Adjusting File (SAF®), XP- Endo Finisher® e a terapia fotodinâmica (TF).
Microorganisms have an essential role in the etiopathogenesis of the pulp and periapical changes. The outcome of endodontic therapy in teeth with necrotic and infected pulp depends on successful disinfection and adequate filling of the root canal system. The elimination of microorganisms can occur by mechanical action, associated with irrigation of the root canals. However, despite recent advances in terms of techniques and tools of preparation, several areas of the canal remain with dentinal debris and microorganisms even after instrumentation. This occurs mainly due to anatomical complexity. Thus, the objective of this literature review is to present different approaches to supplement the disinfection of root canals, including passive ultrasonic irrigation (PUI), final irrigation with chlorhexidine, Endovac®, Self-Adjusting File system (SAF®), XP- Endo Finisher ® and Photodynamic Therapy (PDT).
