ABSTRACT

Purpose: To evaluate the relation between marginal adaptation and depth of gingival sulcus on primary teeth restored with stainless steel crowns. Methods: Depth of gingival sulcus was measured in 114 primary teeth restored with stainless steel crowns on 67 children, both sex, 3 to 6 years old in a Pediatric Dentistry Clinic at the Universidad Autónoma de Tlaxcala, México. The children were divided in three groups: a) experimental (n=30), b) control (n=8) and c) negative control (n=29). Informed consent was obtained and plaque and gingival indexes (Löe and Silness 1967) were taken on six dental surfaces, depth of gingival sulcus was measured with a dental probe and stainless steel crowns were clinically and radiographically evaluated on its marginal adaptation and cervical length. Results: Plaque index and Gingival index were not statistically significant for experimental and negative control groups. 34% of stainless steel crowns showed good marginal adaptation, 33% poor adaptation, 10.5% were short and 7.9% long, 14 % other kind of poor adaptation. Depth of Gingival sulcus was statistically significant on lower right first and second primary molars and for lower cuspids (p›0,05); disto-buccal surface showed the deepest measured of gingival sulcus (2.34 mm), wich was statistically significant (p›0,05). Conclusions: Depth of gingival sulcus was greater on primary teeth restored with long stainless steel crowns and poor marginal adaptation. Plaque presence and gingivitis were related with poor adapted stainless steel crowns.
