Abstract
Objective: Cervical end preparation is an important procedure in fixed partial denture, because if it is inadequate it will increase dental plaque accumulation which is the beginning of periodontal disease. The aim of this study was to analyze the effect of cervical end preparation design on collarless metal ceramic crown to the level of IL-1? in gingival crevice fluid (GCF).
Methods: The study was carried out using by quasi experimental with pre and post test with contol grup design involving 48 subjects. The tooth preparation and the cervical end preparation were made with shoulder, beveled shoulder, and deep chamfer cervical end preparation. The assessment of IL-1? in GCF was measured before and 1, 7, 21 days after insertion of collarless metal ceramic crown.
Results: This study showed that the increase of level IL-1? in GCF on bevel shoulder and deep chamfer was significant different compared with control group (p＜0.05).
Conclusion: Shoulder is a better preparation design for collarless metal ceramic crown.
