The effects of ultrasonic scaling in combination with povidone-iodine solution treatment one time (group A) in comparison with two times (group B) with a one week interval were examined clinically and bacteriologically.
The results obtained were as follows:
1. Clinical findings, with the exception of plaque index, showed improvement in group A as compared with group B.
2. Phase contrast microscopically, both total bacterial count and spirochetal and motile rod incidence decreased after ultrasonic scaling in group A in comparison with group B during all observation periods.
3. Based on synthetic evaluation of clinical and bacterial findings, significant improvement was found in group A as compared with group B.
