DentalVibe reduces pain during the administration of local anesthetic injection in comparison to 2% lignocaine gel: results from a clinical study

BACKGROUND

This study was designed to compare the efficacy of DentalVibe against 2% lidocaine gel in reducing pain during the administration of local anesthetic injection in the adult population.

METHODS

This was a split-mouth open-label, randomized, controlled clinical study conducted in the Department of Oral and Maxillofacial Surgery of a dental institute. Fifty patients who were scheduled for bilateral dental extractions requiring an inferior alveolar nerve block were enrolled in the study. Site A (n = 50) was coated with 2% lidocaine gel followed by a local anesthetic injection, and DentalVibe with local anesthetic injection was used for Site B (n = 50). The primary outcome was pain, which was recorded immediately after the administration of anesthetic injection using the Visual Analogue Scale [VAS 0 - 10].

RESULTS

The VAS pain scores ranged from 4 to 10 for site A and 0 to 6 for site B. Comparison between the two sites showed a statistically significant difference [Mann-Whitney U test value = 51.50, P < 0.001] favoring site B.

CONCLUSION

This study showed that DentalVibe reduces pain during injection of local anesthesia compared to topical anesthetic gel.

The effect of DentalVibe on pain and discomfort during local anesthesia in children: a randomized clinical trial

Objective: To evaluate the effectiveness of using DentalVibe during injection in comparison with the traditional injection technique, regarding pain and discomfort associated with buccal infiltration anesthesia (BIA) in pediatric patients. Method and materials: This randomized clinical trial included 6- to 12-year-old healthy children currently receiving nonurgent dental treatment on the maxillary arch that required BIA. In the control group, subjects received traditional BIA. In the test group, they received BIA with the aid of DentalVibe. A sample of 30 subjects per group was included. The mean ± SD age of the subjects was 9.18 ± 1.66 years. All the subjects were videotaped, and two trained and calibrated evaluators assessed the children's behaviors during the injection using the face, legs, activity, cry, consolability (FLACC) scale independently. Immediately after anesthesia administration, the subjects were administered the validated Arabic version of the Wong-Baker FACES scale ranging from 0 to 10. Results: Female subjects showed significantly higher mean FLACC and Wong-Baker FACES scale scores (2.20 ± 1.82 and 2.93 ± 3.05) compared with males (1.08 ± 1.37 and 1.12 ± 2.09) (P = .008 and P = .006, respectively). Multiple regression analysis showed that regardless of age and treatment group, females had significantly higher mean scores on the FLACC (β = 1.63, P = .002) and the Wong-Baker FACES scales (OR = 4.44, P = .004) than males. Conclusion: The use of DentalVibe did not significantly affect pain, discomfort, or time during BIA among pediatric patients compared with the traditional technique. Female children were more likely to report higher pain and discomfort scores during BIA administration regardless of age and anesthesia administration technique.

The effectiveness of electronic pulsed soft tissue vibration compared with topical anaesthesia in reducing the pain of injection of local anaesthetics in adults: a randomized controlled split-mouth clinical trial

The purpose of this study was to evaluate the effectiveness of an electronic hand-held pulsed vibration device on the pain of local analgesia (LA) injection and physiologic changes. A prospective randomized controlled clinical trial using split-mouth (crossover) design was implemented. The control-side injection was performed after using topical anaesthesia. The experimental side injection was carried out without topical anaesthesia, but with the aid of a switched-on vibration device. Overall, 332 dental LA injections were given to 166 patients for routine exodontia. The pain at penetration and pain during injection were significantly lower in the experimental sides (vibrations sides) compared with those of the controls (P<0.001). Similarly, the heart rate changes at penetration and during injections were significantly lower in the experimental sides (P<0.001). The vibration device was clinically and statistically more effective than topical anaesthesia in the reduction of dental injection pain in adults, measured subjectively and objectively, regardless of the gender, injection technique (infiltration or block) or anxiety level.

Pain assessment during mandibular nerve block injection with the aid of dental vibe tool in pediatric dental patients: a randomized clinical trial

OBJECTIVE

This study aimed to evaluate the effectiveness of DentalVibe in pain reduction during local anesthetic injection compared to traditional injection in pediatric patients.

METHOD AND MATERIALS

This cross-over randomized controlled clinical trial included a sample of 60 children, aged 5 to 7 years, who were selected based on the need for local anesthesia for bilateral mandibular pulpotomy treatment. They were randomly allocated into two groups. Each group received two mandibular nerve block injections, with a 2-week interval as the washing out period. At first appointment, mandibular nerve block injection was performed either with vibration using DentalVibe at the injection site or benzocaine gel 20% applied before local anesthetic injection; the alternative technique was used at the second appointment. In each visit subjective pain was evaluated using the Wong-Baker FACES Pain Rating Scale and objective pain was evaluated using the FLACC (Face, Legs, Activity, Cry, Consolability) scale.

RESULTS

Assessment using the Wong-Baker FACES Pain Rating Scale showed that the mean pain levels in DentalVibe and traditional injection groups were 0.80 ± 1.34 and 2.60 ± 3.22, respectively. The mean pain levels according to the FLACC scale were 2.20 ± 2.04 and 3.13 ± 2.30 in the DentalVibe and traditional injection groups, respectively. Both scales showed statistically significant differences between the two groups in favor of DentalVibe (P < .001). A positive significant correlation between the two scales in the two interventions was recorded, where the Spearman rho was 0.41 for the DentalVibe group, and 0.52 for traditional injection group (P < .001).

CONCLUSION

Compared to the traditional approach, DentalVibe reduced pain sensation during mandibular nerve block injection in pediatric patients.

Efficacy of vibrotactile device DentalVibe in reducing injection pain and anxiety during local anaesthesia in paediatric dental patients: a study protocol for a randomised controlled clinical trial

INTRODUCTION

A current non-pharmacological mean for attaining painless local anaesthesia (LA) is presented by vibrotactile devices. Their concept is to reduce injection pain due to distraction by applying physical stimuli which interfere with pain signals. The aim of this study is to determine the efficacy of the DentalVibe (DV) device in reducing pain and anxiety associated with LA in paediatric patients.

METHODS AND ANALYSIS

The proposed study is a randomised controlled clinical trial with split-mouth design. Included are positive patients aged 8-12 years, requiring buccal infiltration for extraction of two bilateral primary maxillary molars. After dental fear measurement, eligible patients undergo two single-visit treatments with DV device allocated to either first or second LA via computer-generated randomisation sequence. Outcome measures will be self-reported pain felt during LA on Visual Analogue Scale; self-reported anxiety on Facial Image Scale; pain-related behaviour according to Faces, Legs, Activity, Cry, Consolability Scale; heart rate; patient preference to LA technique.Data will be analysed with intention-to-treat concept by Student's t-test for paired samples, Wilcoxon signed-rank test, p<0.05. Pretest on 20 subjects resulted in n=41 patients sample size.
