All of the following have negative influence on the healing of luxation injury in a pediatric patient, except:
• The type of splint and fixation period in multivariate analysis studies were generally not significant variables on healing outcomes.
• Andreasen et al. did find that fixed splinting with orthodontic bands and composite resin splints was a significant variable for the development of intracanal calcification.
• Thus, flexible splints are advocated currently and have shown to provide positive results in maintaining the vitality of the pulp as well as preserving the periodontium.
• The less traumatic application of a wire and composite resin splint showed similar outcomes as teeth which were not splinted.
• Another study of 172 luxation injuries immobilized with rigid splints consisting of cap splints, ligature wires +/- acrylic coverage reported that the fixation period was a significant variable for loss of alveolar bone.
• The mean duration of immobilization in this study was 52 days.
• It is plausible in these instances that longer periods of immobilization resulted in bone loss from periodontitis associated with oral hygiene difficulties.
