Valoración de la sensibilidad postoperatoria entre tratamientos de restauraciones directas con y sin base cavitaria.

Abstract

Introduction: Postoperative sensitivity in composite resin restorations is a common occurrence that causes discomfort in the patient and discomfort for the professional, because it is multifactorial. Clinical research has indicated that up to 30% of study populations have reported post-operative sensitivity after placement of a posterior composite resin restoration. Objective: To evaluate the presence of postoperative sensitivity between treatments of direct restorations with and without cavitary base in posterior teeth made to patients in the "Clinica de Restauradora II" of the Santiago de Guayaquil Catholic University. Materials and methods: Study is observational, transversal and descriptive. Patients with at least one occlusal caries lesion were randomly selected in the posterior teeth using the inclusion and exclusion criteria. The data obtained was recorded with respect to each restorative treatment and a descriptive statistical analysis of frequency and percentages was performed for the variables established in Microsoft Office Excel® 2016. Results: 60 posterior dental pieces were evaluated, of which 30 (50% ) corresponded to treatments of direct restorations with a cavity base and the other 30 (50%) to direct restorations without a cavity base. The prevalence of postoperative sensitivity was 11.7%. Discussion: In several researches it has been reported that the prevalence of postoperative sensitivity after the restoration of posterior teeth is up to 20% higher when the cavity base is placed. Conclusion: The prevalence of postoperative sensitivity in treatments of direct restorations with and without cavitary base in posterior teeth was low and has an undefined multifactorial origin.
