Comparative Evaluation of Mucosal Vibrator with Topical Anesthetic Gel to reduce Pain during Administration of Local Anesthesia in Pediatric Patients: Anin vivoStudy

Abstract

IntroductionUsually discomfort and pain are associated with dental work, especially for young patients. Pain control can be achieved by using anesthesia. Sight of injection can terrify any patient and if the patient is a child it is really difficult to convince them for injections. Alternatives to injections have been explored. Pediatric dentists are using anesthesia in the form of jelly and patch. Recently, the concept of mucosal vibration has been put forward to enhance the effectiveness of local anesthesia.AimThe aim of the present study was to compare and evaluate the effectiveness of lignocaine jelly and mucosal vibration in reducing pain during administration of local anesthesia in pediatric dental patients.Materials and methodsThirty children in the age group 6 to 11 years who required bilateral anesthesia for dental treatment in mandible were selected for this study. Pain was compared using Wilcoxon signed-rank test at the time of injection using Sound, Eye, Motor (SEM) scale as objective criteria and facial pain rating (FPR) scale as subjective criteria after administration of injection by a trained assistant who was blinded to the procedure.ResultsLocal anesthetic injection along with mucosal vibration resulted in significantly less pain (p = 0.001) in comparison with the injections without the use of mucosal vibration.ConclusionThe result shows that mucosal vibration can be used as an effective means to reduce the intensity of pain during local anesthetic injection in dentistry.How to cite this article: Tandon S, Kalia G, Sharma M, Mathur R, Rathore K, Gandhi M.

The effect of vibratory stimulus on pain perception during intraoral local anesthesia administration in children: a systematic review and meta-analysis

“…After removing duplicate articles, 390 records were screened by title and abstract. The full text of the 13 potentially relevant papers was evaluated [ 14 16 18 19 20 21 22 23 24 26 27 28 29 ] and six studies were excluded [ 14 16 26 27 28 29 ]. Reasons for exclusion are given in Table 1 .…”

“…Characteristics of included studies: The characteristics of the included studies are shown in Table 2 . Among these seven studies published between 2014 and 2020, six studies had a crossover design [ 18 19 20 22 23 24 ], and one study had a randomized controlled design [ 21 ].…”

“…Vibratory stimuli for intraoral dental injection-related procedures were obtained by various methods such as direct manual stimulation using cotton roll vibration [ 14 ], specialized attachment devices that fit on the syringe (SMV- Syringe Micro Vibrator) [ 15 16 ], and intraoral vibratory devices such as Dental Vibe® [ 17 ]. Studies reported diversified outcomes with the use of vibration as a counter-stimulatory method to reduce dental injection-related pain in children—positive [ 18 19 20 21 22 ] and no significant difference [ 23 24 ]. On the contrary, few studies have reported that vibration sensation during intraoral local anesthesia administration is perceived as discomfort by the child [ 23 ].…”

Efectividad de dos anestésicos tópicos para la colocación de la grapa. Estudio clínico aleatorizado

“…La anestesia tópica se define como el bloqueo nervioso por la aplicación directa de sustancias en mucosa o piel intacta en el sitio donde se originaría el dolor. Sus objetivos son: 1) que las moléculas del anestésico alcancen las terminaciones nerviosas de los nociceptores en la zona de inicio del dolor, 2) conseguir que la concentración de anestésico sea máxima en el lugar de acción en el menor tiempo posible y 3) que el paso de la solución anestésica al torrente circulatorio sea mínimo para evitar efectos sistémicos indeseables 5,7 .…”

“…La FPS-R se acompañó de la siguiente explicación: De hecho, hay autores que afirman que el efecto de la anestesia tópica tiene un componente psicológico, debido a la naturaleza multidimensional de la percepción dolorosa y por tanto a la influencia significativa de factores como la ansiedad, el miedo y la percepción individual en la reducción de la sensación de dolor 5,13,22,28,29,32 .…”
