The aim of this study was to identify and evaluate some structural aspects of the dental care supply and demand, its mechanism and then characterizes the periodontal preventive activity in the region of Port-au-Prince. We had conducted between January and February 2012 an epidemiological survey, using a questionnaire that we had administered to the dentists operating in Port-au-Prince. Our analysis of 230 questionnaires revealed a dental practice that is almost private and which is largely carried out by men. Our results also indicated that the dentist population in this region happens to be quite young. Most of the demands resulting from dental consultation are related topain or bleedings. The preventive periodontal act was the most practiced.Althoughmany interventions has been performed in periodontal surgery. Practitioners in the two categories think that a reference should be addressed in severe cases and even if the number of years of experience affect their position towards the built-in support.A fact is that the two groups are agreed that this type of approach is the ideal.

Background: Local delivery of antimicrobials in sustained or controlled delivery systems are used to enhance the effect of non-surgical periodontal therapy.

Aim: Aim of the present study was to investigate and compare the effectiveness of subgingivally delivered antimicrobial bio-absorbable controlled release 0.4% Moxifloxacin gel and 0.1% Ofloxacin gel as an adjunct to scaling and root planing in the treatment of chronic periodontitis.

Methods and material: A total of 62 patients suffering from chronic periodontitis were randomly divided into group A and group B. The group A were treated with Scaling & Root Planing (SRP) in combination with subgingival application of 0.4% Moxifloxacin gel. The group B received SRP and subgingival application of 0.1% Ofloxacin gel. Probing Depth (PD) and Clinical Attachment Level (CAL) were recorded at baseline, 3, 6 and 9 months.

Statistical analysis: Statistical analysis was done using oone way Analysis of Variance (Anova) to test the difference between groups.

Results: The PD scores in experimental group A were 5.22, 3.71 and 3.71 mm and for the experimental group B were 5.30, 3.96 and 3.96 mm at baseline, 3 months, 6 months and 9 months respectively.

Conclusion: Overall, both the therapies led to significant improvements of the investigated parameters. Thus in periodontal pockets with PD of ≥ 5 mm, a single subgingival administration of a 0.4% Moxifloxacin gel and 0.1% of Ofloxacin gel as an adjunct to SRP may result in additional PD reduction compared to SRP alone
