Clinical effectiveness and soft tissue compatibility of a temporary restorative material.

OBJECTIVE: The purpose of this six-week study was to evaluate in vivo the effectiveness of Systemp.inlay as a temporary restorative material. METHOD: Subjects with the proper indication for a class II restoration were entered into the study. Twenty-three subjects and twenty-nine temporary restorations were evaluated at time of placement, three and six weeks. Two faculty members were calibrated to evaluate the material. Following the six-week trial, the temporary restorative material was removed and the test teeth were restored with a definitive restorative material. RESULTS: The temporary restorative material provided mechanical and anticariogenic protection of tooth structure while preventing dental sensitivity and patient discomfort. It promoted soft tissue health as evidenced by the enhanced plaque and gingival indices found associated with the temporarily restored teeth. Its ease of placement and removal makes it an attractive alternative for the dental practitioner. The change in color of the material over the six-week duration of the study may limit its use to posterior teeth and to lingual/palatal surfaces of anterior teeth. CONCLUSION: Ease of placement and removal and retention of the temporary restorative material were extremely good. Marginal and surface integrity of the material was maintained and no or minimal sensitivity was reported throughout the study. The material did not promote the accumulation of plaque nor result in gingival inflammation. The color change noted was not of clinical importance. Therefore, this temporary restorative material was demonstrated to be clinically effective in Class II cavity preparations.
