Abstract
BACKGROUND: Pain from local anesthetic injection makes patients anxious when visiting a dental clinic. Therefore, the purpose of this study was to determine differences in pain according to types of local anesthetizing methods, and to identify the possible contributing factors (e.g., dental anxiety, stress, and sex).
METHODS: The patients of this study were composed of thirty-one patients who were treated due to chronic periodontitis. They underwent open flap debridement in maxillary premolar and molar areas. A randomized, split-mouth, single-masked clinical trial was implemented. Dental anxiety scale (DAS) and perceived stress scale (PSS) were examined before the surgery. Two lidocaine ampules for each patient were used for local infiltration anesthesia (supraperiosteal injection). Injection pain was measured immediately after local infiltration anesthesia with visual analogue pain scale (VAS) questionnaire. The results from the questionnaire were utilized to compare the degree of pain patients feel when conventional local anesthetic technique (CNV) is used versus when computer-controlled anesthetic delivery system (CNR) is utilized Result: DAS and PSS did not correlate to the injection pain. VAS score was lower for the CNR than for the CNV regardless of the order in which the anesthetic procedures were applied. The VAS score did not differ significantly with sex. The Pearson coefficient for the correlation between the VAS scores for the two systems was 0.80, also indicating a strong correlation.
CONCLUSION: Within the limitations of the present study, a relief of injection pain was observed in utilizing the computer-controlled anesthetic delivery system.
