Pain, Postoperative Clinical Trial
Official title:
Topical Intrapocket Anesthesia With Prilocaine and Lidocaine as Alternative to Injectable Anesthesia During Scaling and Root Planing - A Randomized Clinical Trial
Injectable anesthesics previous to subgingival scaling and root planing (SRP) presents some disadvantages like fear of the needle insertion, long-lasting effect and prolonged dampening of adjacent tissues. This study will compare the intrapocket anesthetic effectiveness of a skin topical anesthesic EMLA with intrapocket 2% benzocaine, intrapocket placebo and injectable anaesthesia for SRP in a Split-mouth, double-blind, clinical trial study.

Inclusion Criteria: - eligible individuals for the study were selected from those requiring SRP with at least 2 experimental teeth in four of the six sextants. - each experimental teeth had to present = 1 site with probing depth = 5 mm associated with BP after treatment of gingivitis (without marginal bleeding). - furthermore, individual should present = 18 years-old, have not ever done periodontal treatment and be able to understand Verbal Scale (VS) and Visual Analog Scale (VAS). Exclusion criteria: - patients that related allergy history or sensitivity reaction to any used amide or ester anesthetics form, - who received anesthesia or sedation 12 hours before SRP, - who presented ulcerated lesions or abscesses in the oral cavity, - who presented oral pathologies with immediate surgical, - who had prior abuse alcohol history, pregnant women, - who presented uncontrolled hypertension or - who had participated in a clinical trial of investigational drug before four months from the beginning of this study. |

Primary | Pain and discomfort | For each experimental tooth, the patient was asked to indicate the intensity of pain and discomfort experienced intraoperatively using the VAS (VAStrans) (5 minutes after the start of the instrumentation in each tooth) and postoperatively (VASpost) immediately after the end of instrumentation of the respective tooth. At the end of the procedure, the patient was asked to also describe the pain sensation of the tooth using VS as: no pain (0), mild pain (1), moderate pain (2), severe pain (3), or extremely severe pain (4). | For each tooth was evaluated intraoperative pain using the Visual Analog Scale (5 minutes after the start of the instrumentation) and postoperative immediately after instrumentation. At the end of the procedure, was asked Verbal Scale, for 4 weeks. | No |
Secondary | Patient satisfaction with anesthesia | Patient satisfaction with anesthesia was determined at the end of all treatment sessions using the following four categories: very satisfactory, satisfied, not satisfied, and completely unsatisfactory. | Determined at the end of all treatment sessions, for 4 weeks. | No |
Secondary | Injectable anesthetic requirement | Percentage of subjects injectable anesthesia requirements in different anesthetic groups. In case of occurrence of pain during the subgingival SRP, an additional dose of the same anesthesic was repeated. If pain persisted after this second application, then an anesthesia infiltration/block was performed. | If pain persisted after this second application, then an anesthesia infiltration/block was performed, for 4 weeks. | No |
Secondary | Adverse Events | When each patient returned for the next treatment session, they were asked about the occurrence of pain, discomfort, localized ulceration, edema, or desquamation of the oral mucosa. | Determined when each patient returned for the next treatment session, for 4 weeks. | No |
