RESUMO
OBJECTIVES: The aim of the present case series was to evaluate the clinical and microbiological effects of a single session of mechanical and manual scaling and root planing (SRP) combined with the use of two different chlorhexidine formulations in the treatment for generalized chronic periodontitis. METHODS: Ten patients affected by chronic periodontal disease with periodontal probing depth (PPD) ≥ 5 mm were treated with SRP plus local chlorhexidine. In each patient, similar teeth, treated with SRP with the adjunctive use of chlorhexidine digluconate and dihydrochloride or chlorhexidine gluconate, respectively, were selected and assigned to a test and a control group. In both groups, PPD, bleeding on probing (BOP) parameters, total bacterial counts (TBC) and quality of periodontal bacteria at time 0 and 6 weeks after treatment were measured. RESULTS: PPD significantly decreased over time both in the test and in the control group; however, no significant differences between the two groups were observed. BOP and TBC were significantly lower in the test than in the control group 6 weeks after treatment. In the post-treatment revaluation, a significant decrease both in the treatment and in the control group, for each of the single periodontal pathogens, was observed. CONCLUSION: In this study--a preliminary case series with small sample size and short follow-up--the adjunctive use of chlorhexidine (CHX) to SRP resulted in clinical and microbiological benefits in the treatment for generalized chronic periodontitis. A CHX gel formulation consisting of CHX digluconate and CHX dihydrochloride seems to lead some additional benefits over SRP plus CHX gluconate in the short term. Additional investigations are needed to evaluate the effectiveness of this antiseptic therapy.

Xerostomia, jointed to local or general diseases or to drug therapy, is a very heavy problem for complete denture patients. Lack of saliva produces changes in the oral mucose membrane and instability of the complete denture. The Authors suggest a change in the complete denture consisting in small tanks full of solution making up for the lack of saliva. The new method proved to be good, easy to make, and very cheap.

The cementation is a basic step in the fixed prosthesis rehabilitation. Therefore, it is very important to know the main chemical, physical and biological properties of luting cements. The tensile strength of some dental cements for fixed cast restorations has been studied. Results obtained showed that glass ionomer and zinc oxide-eugenol with Eba are better than the other dental cements. The difference between the data obtained showed to be statistically significant.
