Abstract

BACKGROUND We wanted to clinically evaluate the efficacy of lidocaine bioadhesive patches for extraction in paediatric dentistry and assess the comfort and pain response by sound eye motor (SEM) scale and intensity of pain using the visual analogue scale (VAS). METHODS A total of thirty-five co-operative children of age group 8 - 12 years without systemic diseases who needed dental extraction participated in the study. Extraction was carried out using customized lidocaine bioadhesive patches as anaesthetic agent. Evaluation of comfort and pain response was done by sound eye motor scale and intensity of pain using the visual analogue scale. Statistical analysis was done with SPSS version 2.0. Comparison of SEM scale and VAS scores between different subgroups was done using a chi-square test. P value less than 0.001 was considered statistically significant. RESULTS Children of higher age groups belonging to both the genders demonstrated less perception to pain during extractions using lidocaine patch. During extraction of firm teeth and teeth with Grade I mobility, perception of pain was more in girls. Maxillary arch extraction in children with various grades of mobility perceived less pain. Irrespective of age, gender and arches,teeth with Grade II and Grade III mobility were extracted with minimal VAS and SEM score. CONCLUSIONS Bioadhesive patches serve as a potential non-invasive alternative to traditional modes of local anaesthetic delivery with the advantage of eliminating needle phobia and possible negative influence on the behaviour.
