Estado gingival por el uso de coronas metálicas en la clínica de odontopediatría UCSG. Semestre A-2019.

Abstract

Abstract: Introduction: The gingival groove is the biological space between the inner side of the marginal gum and the tooth and the shape of the biological-functional unit of the periodontium. A healthy periodontium has the shallow gingival groove that changed from 1.5 mm to 3 mm in the permanent dentition. With the use of metal crowns it is possible to preserve the temporary dental organ until its physiological exfoliation, however there are controversies in the literature regarding gingival tissue with restorations of steel crowns. Objective: To assess the gingival status by the use of metal crowns in the UCSG pediatric dentistry clinic. semester A-2019. Materials and methods: A retrospective observational study was carried out, in the sample it is made up of 68 pediatric patients with restorations of metal crowns who were treated at the UCSG dental clinic in semester A -2019. Results: The universe was comprised of 68 patients from 6 to 9 years of age in both sexes, the age range that I present was greater than 8 years with a (57%), being the minimum age of 6 (7%) and the maximum of 9 (12%), the highest prevalence was female sex, among which 29 boys (43%) and 39 girls (57%) were determined. Table 1. When evaluating the results, a higher percentage of reduced marginal adjustment was found in the grade B (long crowns) of 22 (32%) patients in both sexes, and a minimum average in grade C (often marginal adjustment) with 6 (9%) Table 2. It was observed radiographically that the piece # 74 present poor marginal adaptation in the cervical area grade B (long crowns) in 6 patients. Table 3 It was analyzed that 18 (26%) patients had an invasion of the gingival tissue by cementation of the crown with 1 mm greater, 33 (49%) patients had equal to 1 mm was the percentage higher than I present, and 17 ( 25%) I present invasion of the gingival groove smaller than 1mm. Table 4. Conclusion: It was concluded that a poor marginal adaptation of the crown can cause a degree of inflammation of the gingival tissue. There is not enough scientific evidence to support that crown adaptation is the risk factor that causes gingival damage. Excess cement greater than 1 mm subgingivally may be an indicator that produces gingival inflammation. Even so, the results were significant, which shows that it is an adequate technique and good oral hygiene favors gingival health when placing a metal crown.
