Abstract

Objective

To assess the anesthetic efficacy of articaine with the needle-free/Comfort-in™ method compared to the conventional needle method. To assess pain during anesthesia application, onset of anesthesia and patient`s self-reported quality of life-related to oral health after the dental emergency appointment.

Materials and methods

This parallel, randomized clinical trial was conducted by a single operator/dentist in the state of Maranhao, northeast of Brazil. Included participants were adult dental patients with one molar (maxillary) or premolar (maxillary or mandibular) tooth diagnosed with symptomatic irreversible pulpitis. The primary outcome was the anesthetic efficacy, measured using a combination of electrical and cold pulp tests (cold + EPT) and the Numerical Rating Scale (NRS). Secondary outcomes were pain during anesthesia application, onset of anesthesia, and patient`s quality-of-life (measured with the OHIP-14).

Results

62 patients were randomized in the anesthesia needle-free group and Comfort-in group (34.26 ± 10.786 × 33.29 ± 8.399 years old, respectively). The group of patients in the Comfort-in group had 71.0% success. Patients from the Comfort-in group reported statistically lower pain during the anesthesia application than patients from the conventional group (2.13 ± 2.172 × 6.03 ± 3.146 NRS scores, respectively) as well as immediately after the anesthetic procedure. Patients self-reported negative impact in quality of life was similar between groups before (p > 0.05) and after (p > 0.05) the dental emergency.

Conclusions

Comfort-in™ had similar efficacy to the conventional needle method.

Clinical relevance

This trial showed that it is possible to anesthetize patients with tooth pulpits without using needles to provide comfort mainly to anxious patients.
