Evaluation of Anesthetic Efficacy in Extraction on Mandibular Molars

Tooth Extraction Clinical Trial

Official title: Evaluation of Anesthetic Efficacy in Extraction on Mandibular Molars With Periapical Granuloma

Status Recruiting

Clinical Trial Summary

To evaluate subjectively and objectively the quality and efficacy of local anesthetic block with mepivacaine in simple extraction of mandibular molar. Provide and collect information such as: signs and symptoms, quality of anesthetic block, quantify pain and / or discomfort, as well as medication used, both preoperatively and postoperatively.

Clinical Trial Description

Anamnesis and clinical diagnosis of patients, with indication of extraction, will be performed by the Emergency Department of the School of Dentistry of the University of São Paulo (SDUSP). Of these, 80 patients with mandibular molar teeth extraction, with and without apparent apical lesion radiographically identified in the initial imaging examination will be included. They must be over 16 years old, with good judgment and good general health, who have availability of return to the clinic for postoperative follow-up and aware of the Term of Consent.

After the anamnesis, clinical and radiographic examinations for diagnosis and inclusion in the study, they will receive information on the procedure to be submitted, mainly on the quality of the local anesthetic block, quantification of pain and / or discomfort, and what will occur on the days after the procedure, such as guidelines and post-operative care (PO).

The clinical procedure (extraction) will follow the protocol of attendance of the Emergency Department of SDUSP, which is consistent with the surgical practice in force in this School and in other Dentistry Schools. In clinical care, patients will be questioned about the presence of discomfort and / or pain, indicated on the visual analogue scale (VAS score 0, score 1, score 2 or pain score 3). They will be informed about the effects of anesthesia, the use of the pulptest sensitivity test, absence of sensitivity in soft tissue and pulp after anesthesia, and the need for complementation with more local anesthetic (Mepivacaine and Noradrenaline) and / or incorporation of other anesthetic techniques.

To obtain basal tooth responsiveness patterns, prior to anesthesia, the pulptest will be applied to vital teeth of the quadrant that will receive intervention. The same will be reapplied after the injection of the anesthetic, in order to verify the installation of the blockade. Only after the anesthetic blockade has been confirmed and installed, both pulp ("Pulptest"), and soft tissues, the patient will be included in the research, initiating the surgical procedure. Any discomfort or complaint that the patient may have during the transoperatory period will be considered and, if necessary, we will use anesthetic complementation, which is recorded. In the postoperative period, these patients will have the opportunity to report some discomfort and pain, through a questionnaire, which will be filled and returned on the day of removal of suture, as well as intercurrence and / or need to use the suggested medication in case of pain.

The information obtained in this study will be inserted in Excel spreadsheet for descriptive analysis, statistics and comparison. ;
