ABSTRACT

OBJECTIVE:

The aim of the present study was to investigate the correlation between initial alveolar bone density of upper central incisors (ABD-UI) and external apical root resorption (EARR) after 12 months of orthodontic movement in cases without extraction.

METHODS:

A total of 47 orthodontic patients 11 years old or older were submitted to periapical radiography of upper incisors prior to treatment (T1) and after 12 months of treatment (T2). ABD-UI and EARR were measured by means of densitometry.

RESULTS:

No statistically significant correlation was found between initial ABD-UI and EARR at T2 (r = 0.149; p = 0.157).

CONCLUSION:

Based on the present findings, alveolar density assessed through periapical radiography is not predictive of root resorption after 12 months of orthodontic treatment in cases without extraction. .
RESUMO

OBJETIVO:

avaliar a correlação entre a densidade óssea alveolar inicial dos incisivos centrais superiores (DOA-IS) e a reabsorção radicular apical externa (RRAE) após 12 meses de movimentação ortodôntica em casos sem extração.

MÉTODOS:

quarenta e sete pacientes ortodônticos (maiores que 11 anos) foram submetidos ao exame periapical dos incisivos superiores no pré-tratamento (T1) e 12 meses após (T2). Mensurou-se a RRAE no intervalo de 12 meses, bem como a densidade óssea alveolar inicial da região apical desses dentes por meio da fotodensitometria.

RESULTADOS:

não houve correlação estatisticamente significativa entre a DOA-IS inicial e a RRAE em T2 (r = 0,149; p = 0,157).

CONCLUSÃO:

a densidade alveolar avaliada pela radiografia periapical não se apresentou como fator de interferência ou preditivo para reabsorção radicular após 12 meses de tratamento ortodôntico sem extração. .
