Introduction:

Antimicrobial therapy after scaling and root planing treatment in the elderly has not been evaluated at the "Mártires del Moncada" Provincial Teaching Stomatology Clinic in Santiago de Cuba.

Objective:

To evaluate the effectiveness of tetracycline and azithromycin in the treatment of scaling and root planing in the elderly.

Method:

Quasi-experimental study of therapeutic intervention, carried out between 2018 and 2019, on 30 patients with the age of 60 and over and diagnosed with chronic periodontitis. Three groups with 10 cases were created using the simple randomized method. Group 1 treated with the conventional technique and groups 2 and 3, after using the same technique, a subgingival concentration of tetracycline and azithromycin was applied respectively and surgical cement placement for 7 days. Variables such as age, sex, clinical picture, evolution of signs and symptoms at the seventh day, 1 and 3 months, and healing effectiveness were used. The statistical validation was through the Chi-square test, with a 95% reliability and the antimicrobial effectiveness, through the Analysis of Variance ANOVA.

Results:

Predominance of the group age between 65 and 69 years and female sex, persistent gingival inflammation in 30,0 % of group 1 at the third month, decreased the depth of the catheterization and there was a clinical insertion gain, improving their averages in time. A 100.0% healing effectiveness was achieved in groups 2 and 3.

Conclusions:

High effectiveness of subgingival topical application of tetracycline and azithromycin with surgical cement, over patients treated with conventional scaling and root planing.
