The clinical and microbial effects of ultrasonic scaling in combination with povidone-iodine solution were examined in patients using the following three ultrasonic scaling systems in combination with povidone-iodine solution and root planing. Four different sites, one in each quadrant, were randomly selected in each of 10 periodontal patients participating in this study. Each patient received the following treatments : ultrasonic scaling in combination with povidone-iodine solution performed one time at one site (Group A), two times at one-week intervals at another site (Group B), two times at two-week intervals at the third site (Group C), and root planing alone at the fourth site (Group D) .<BR>The results were as follows :<BR>1. Clinical findings, except for plaque index, showed improvement in groups B and C as compared with group A throughout the observation periods.<BR>2. By phase-contrast microscopic observation, both total bacterial count and spirochetal and motile rod incidence decreased in groups B and C as compared with group A throughout the observation periods.
