Abstract
Background: Dental eruption pathways could be influenced by several factors, both general and local, with different prevalence and morbidity. This study aims to report our experience of pediatric impacted teeth due to local factors, with the exclusion of the third molars, illustrating their prevalence, diagnostic and therapeutic pathways, and treatment outcomes. Methods: The inclusion criteria were minor age (<18 years) and the presence of impacted teeth due to a local cause, excluding wisdom teeth. The complete diagnostic and therapeutic procedures and their outcomes were described. The relationship between the treatment and the outcomes was assessed with a chi-square test. Results: One hundred twelve patients with a single impaction were included in the study. The local causes of single impaction were: 63 odontogenic cysts (57%), 24 supernumerary teeth (21%), 17 odontogenic tumors (15%), and eight primary bone lesions (7%). During the follow-up period, 83 teeth erupted spontaneously 12-36 months following surgery (74%), 12 were extracted during surgery (11%), and 17 needed orthodontic traction to achieve their aesthetic and functional position (15%). The relationship between mini-invasive surgery and spontaneous eruption was significant (p < 0.00001). Conclusions: Within the limitations of this study, mini-invasive surgical treatment preceded by a correct diagnosis may lead to a spontaneous eruption of permanent teeth, avoiding further orthodontic intervention and premature loss of permanent teeth.
