Brief Summary:
Mechanized instrumentation systems stand out amongst various devices used in modern Endodontics. Its use in Pediatric Dentistry, its action in primary teeth, has been in the center of many discussions and laboratory studies. Nevertheless, up to now, a lack of clinical studies on this issue can be found. Our objective is to conduct a double blinded, 2 years follow up clinical trial to compare the success of endodontic treatment in primary teeth using mechanized reciprocating instrumentation to the use of manual instrumentation.
Detailed Description:
With the approval of the Ethics Committee of University of São Paulo, after clinical and radiographic examination, patients in search for endodontic treatment in primary teeth will be invited to take part in the study. The participants of the study will be randomized to one of two groups (manual or reciprocating instrumentation). Endodontic treatment will be held by a specialist according to the randomized group. A blinded examiner will proceed one week, 3 months, 6 months, 12 months and 24 months follow ups. Clinical and radiographic conditions of endodontic treatments will be analyzed to classify them as Success or Failure. The unit of analysis will be the teeth; hence, each participant may have more than one tooth included in the study. The randomization will be performed considering the tooth. Data analysis will consider the cluster nature of the sample.
The primary outcome of the study will be the success rates according to the groups. The longevity of treatments will be evaluated by estimating survival rates by Kaplan-Meier and Cox regression. The differences between survival rates of both groups will be through Cox regression adjusted for the cluster nature of the sample (more than one tooth per participant), considering a level of significance of 5%.
