[Article in English, Italian]


Aim: This study was carried out to compare a conventional manual instrumentation with an ultrasonic technique (Odontoson M) in scaling and root planing periodontal treatment. The effects of subgingival irrigation with 10% iodised solution in association with Odontoson M were studied.

Methods: Sixty patients were selected: they were suffering from adult periodontitis, aged between 35 and 65 and non-smokers. They were randomly divided into 3 groups (Gs1, Gs2, Gs3). Gs1 was treated with curettage using Gracey curettes, Gs2 was treated with scaling and root planing using Odontoson M, while in Gs3 scaling and root planing with Odontoson M irrigated with a 10% iodised solution were performed. Clinical parameters (probing depth, bleeding on probing, dental mobility, loss of attachment level) were measured before treatment (T0), after 30 days (T1), after 90 days (T2) and after 120 days (T3).

Results: No statistical significant differences between Gs1 and Gs2 were observed. The improvement of clinical parameters in Gs3 was greater and statistical significant differences with other groups treated were recorded.

Conclusions: There are no significant differences between the effectiveness of scaling and root planing with manual instruments and with Odontoson M. The 10% iodised solution used such as topic antiseptic carries out greater effects in not surgical periodontal treatments.
