Sažetak
Intraoral local anesthesia is essential for dental care. However, it is often perceived by some patients as unpleasantly
painful and in some cases as the only painful part of the treatment. The purpose of this prospective single blinded clinical
study was to compare pain in one of the most commonly used conventional single-stage injections of traditional inferior
alveolar nerve (IAN) block with a two-stage IAN block technique. Subjects and methods: Upon approval of the ethics
research committee, a prospective parallel two-group single blinded comparative in vivo study was performed in which
the Heft-Parker visual analog scale was used to assess pain by subjectively assessing the entire injection procedure. Data
were statistically analyzed using the Statistical Package for Social Sciences v. 17.0 using independent sample MannWhitney U test. Results: A total of 102 adult subjects (mean age 4.15±17.13 years) with uncomplicated medical history
participated in the study. Statistical analysis confi rmed that difference in the results on pain assessment between the two
compared groups was not signifi cant, i.e. there was no difference in pain perception between the conventional singlestage and modifi ed two-stage IAN block injection technique. Conclusion: The two-stage injection did not reduce pain from
needle insertion signifi cantly in female and male patients regardless of age, as compared to the traditional IAN techniques.
The results of the present study suggest that dental operator should be aware of pain and discomfort of injecting local
anesthesia, along with the effi cacy of various techniques.
