Clinical Evaluation Of A Micro-Hyride Composite : 2 Years Follow-Up Z. Baccouche*, H. Tassery (Faculté d’Odontologie Marseille. Université de la Méditerranée. France) New dental resin composites were proposed to replace amalgam restorations. Despite the aesthetic advantages of these new materials, long term clinical evaluations should valid their current uses.   Objectives: The purpose of this study was to investigate the clinical performances of a micro-hybride dental resin composite at baseline, 6 months and 24 months.   Materials and methods: 66 classe II lesions (20 patients) were restored with a bonding agent / composite combination (Syntac Sprint / Tetric Ceram). The restorations were clinically evaluated using the modified USPHS criteria. The clinical data expressed in percentage were summarized in the table herewith.   Criteria % value (15 days - 6 months - 24 months) A B C D Present Absent Surface texture 100-94,1-87,8 0-5,9-12,2         Color match 97,4-91,27-85 2,6-8,73-15         Marginal integrity 100-95-90 0-5-15         Anatomical form 100-100-100           Patient complaints 100-100-100           Sensibilities 90,76-0-0 9,24-0-0         Recurrent caries           100 Marginal discolorations 100-92,84-86,8 0-7,16-13,2         retention rate         100   Proximal contact 97-0-0 3-0-0         Self pain scale from 0 to 10 in % 0 1 2 3       25 25 35 15       24 months later the clinical evaluations of this combination gave encouraging results . However, only an extented period over 5 years will reveal whether these shortcomings recorded after 24 months will be clinically relevant for the longevity of the class II restorations.
