A new ultrasonic system in initial periodontal therapy: clinical efficacy and perception of pain / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the clinical efficacy and perception of pain during initial periodontal treatment using Vector-system and a conventional ultrasonic system.</p><p><b>METHODS</b>Thirty-eight patients with mild to moderate periodontitis were debrided using both A-system (Vector-system) and B-system (Suprasson P5 Newtron) in a split mouth design. At baseline, one month after treatment, plaque index (PLI) and bleeding on probing (BOP) were recorded and probing depth(PD) was measured. A verbal analogue scale (VAS) was used to evaluate the perceived pain right after the treatment.</p><p><b>RESULTS</b>At one month evaluation, all areas showed an improvement in clinical parameters. No statistically significant differences in PD and BOP could be observed between areas treated by two different systems, while A-system contributed to greater improvement in PLI than B-system. Patients treated with A-system [(22.5 +/- 7.5) mm] experienced about 60% the amount of pain compared with the conventional ultrasonic device [(37.2 +/- 11.3) mm].</p><p><b>CONCLUSIONS</b>During initial periodontal treatment for the patients with mild to moderate periodontitis, A-system could achieve a comparable clinical efficacy and reduced pain sensations to conventional ultrasonic device.</p>
