ABSTRACT


Aim

To study incidence and distribution of deciduous molar ankylosis. MATERIALSAND

Methods

Study
design: longitudinal retrospective study. A total of 512 consecutive subjects (aged 5 to 15 years) were examined at the
Orthodontics and Paediatric Dentistry Department of the Genoa University School of Dentistry; for each subject an
ortopantomography x-ray was taken.

Results

Thirty-four children were affected by deciduous molars ankylosis
(6.6). A statistically significant difference was revealed between the distributions: the lower deciduous molars were
ankylosed more frequently than the upper ones (P<0.001); the second deciduous molars were ankylosed more frequently than the first molars (P<0.001). No statistical significance was found between sex and number of infraoccluded teeth (P 0.74).

Conclusion

This study found an incidence of deciduous molar ankylosis of about 6.6; the lower
deciduous molars and second deciduous molars were ankylosed more frequently (P<0.001).
