The aim of this investigation was to determine if cavitation occurred around dental ultrasonic scalers and to estimate the amount of cavitation occurring. Three styles of tip (3 x TFI-10, 3 x TFI-3, 3 x TFI-1) were used, in conjunction with a Cavitron SPS ultrasonic generator (Dentsply, USA), to insonate terephthalic acid solution. The hydroxyl radical, [*OH], concentration, produced due to cavitation from the scaler tips, was monitored by fluorescence spectroscopy. Cavitational activity was enhanced at higher power settings and at longer operating times. The tip dimensions and geometry as well as the generator power setting are both important factors that affect the production of cavitation.

OBJECTIVE: To observe the effect of clinical therapy of using six flavor glutinous rehmannis pill on chronic adult periodontal inflammation. METHODS: 120 adult patients who have been cured for their periodontitis were selected and divided into two groups randomly. Control group was only treated with SRP (scaling and root planning), and test group was requested to take six flavor glutinous rehmannis pills orally for 5 months after SRP. RESULTS: After taking the medicine for 5 months, RPD (reduction in probing depth) was 0.43 mm, GAL (gain in attachment level) was 0.22 mm and was quite different from the control group (P < 0.01) . CONCLUSION: SRP together with six flavor glutinous rehmannis pill is better than pure SRP in RPD and GAL, it is one kind of taking medicine for improving resistibility and maintenance therapy.
