Abstract

SOUZA, Maria Lúcia Almeida Haueisen et al. Selective Alveolar Corticotomy to Intrude Overerupted Maxillary First Molars: Analysis of Pulp Vitality. Int. J. Odontostomat. [online]. 2017, vol.11, n.2, pp.231-236. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2017000200017.

The excessive and prolonged orthodontic treatment might result in loss of pulp vitality. Selective alveolar corticotomy is an alternative to accelerate the orthodontic treatment in adults. This study aimed to evaluate the impact of selective alveolar corticotomy associated with orthodontic intrusion on pulp vitality of overerupted maxillary first molars. Six individuals with extruded maxillary first molars were randomly selected to undergo corticotomy as coadjuvant therapy for intrusion. Pulp vitality was evaluated with thermal (Endo-Ice and Heated gutta-percha) and electric tests before the surgical procedure and after intrusion (90 days). The intrusion of all teeth was obtained (mean 2.26 ± 0.52 mm), and all teeth responded positively to pulp vitality tests before and after intrusion. This suggests that selective alveolar corticotomy did not promote pulp damage, and can be considered an effective and safe auxiliary method to intrusion of overerupted maxillary molars.

Keywords : selective alveolar corticotomy; orthodontics; dental pulp test.
