title: Clinical evaluation of direct composite restoration done for midline diastema closure - long-term study.
abstract: OBJECTIVE
  The aim of this study was to evaluate clinically the performance of composite resin used to restore midline diastema between the maxillary and mandibular central incisors.
  
  
  METHODS
  Direct composite restorations were done for 45 patients with midline diastema between the maxillary and mandibular central incisors. Standard protocols were followed for the placement of composite resin for the diastema closure, and recall visits were made for every 6 months for a period of 60 months for evaluation of the success of these restorations made. Qualified dental personnel examined the restorations made.
  
  
  RESULTS
  Clinical evaluations were done after the restorations had been in place for an average of 6 months. Results indicate that none of the restorations were totally lost, and resulting in a 91% overall retention rate for the period of 60 months. About 62% of the restorations made had no noticeable color difference with that of the adjacent tooth, and gingival health indicated 73% of the sample was without any signs of inflammation.
  
  
  CONCLUSIONS
  Composites restored for diastemas exhibit satisfactory survival rates placed with recommended placement protocols and without occlusal loading.
