Use of bioactive materials and orthodontic band as a minimal intervention alternative in primary teeth with deep caries lesion: case report

Abstract

The minimal intervention philosophy emphasizes preserving tooth structure and keeping teeth vital and functional until they are exfoliated. Within this concept, the technique of selective removal of decayed tissue followed by restoration of the tooth is recommended. This work aims to present a clinical case report of a minimally invasive treatment in a pediatric patient with deep carious lesions. Patient, 5 years old, female, attended for dental care at a Private Postgraduate Institution in Pediatric Dentistry – Serra, Espirito Santo. After clinical and radiographic examination, a deep caries lesion was identified in the inner third of the dentin in teeth 84 and 85, with no history of pain and no chronic changes in the furcation region and root apex. In order to stop progression and preserve pulp health, it was decided to perform selective removal of decayed tissue in both teeth restoration with bioactive bulk fill composite resin in tooth 85 and orthodontic band cementation and restoration with conventional glass ionomer cement in tooth 84. Clinical and radiographic follow-up was carried out for 90 days. It was possible to conclude that the minimal intervention approach for the treatment of primary teeth with deep carious lesions presented good clinical and radiographic results. The intervention interrupted the progression of the caries lesion, without pulp exposure, making it possible to restore the function of the teeth, in addition to maintaining space in the dental arch. However, the need to monitor the case to ensure the patient's health stands out.
