A total of 37 class I and II restorations (compound and complex type) were placed in 6 premolars and 31 molars. The restorations were reviewed clinically at 6 months (baseline) and 12 months using modified USPHS codes change criteria for marginal adaptation, post-operative sensitivity, pulpal pain and secondary caries criteria. Photographs and x-rays were obtained for restorative analysis. Results of 12 months evaluation showed 5 restorations having little marginal leakage (B score) and 1 patient had minor pulpal symptom and post-operative sensitivity (B score). No secondary caries or bulk fracture was detected. The majority of restorations exhibited A scores of the evaluated criteria. After 12 months, restorations combining base of short fiber reinforced composite resin as substructure and surface layer of hybrid composite resin displayed promising performance in high load bearing areas. 1 6 2012 41 45 TODENTJ-6-41 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2011-11-05 2011-12-30 2011-12-30 2012-1-6 http://creativecommons.org/licenses/by-nc/3.0/ 10.2174/1874210601206010041 1553505315 https://opendentistryjournal.com/VOLUME/6/PAGE/41/ https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.pdf https://opendentistryjournal.com/contents/volumes/V6/TODENTJ-6-41/TODENTJ-6-41.xml J Am Dent Assoc Bowen RL 66 57 1963 Bowen RL.
