GALVAO, Anna Karyna Fernandes de Carvalho et al. Prevalence of tooth injuries in patients with neuropsychomotor disorder. Rev. odontol. UNESP [online]. 2017, vol.46, n.6, pp.351-356. ISSN 1807-2577.


Traumatic dental injuries are distressing experiences in children, which promote both physical, emotional and psychological changes.


To evaluate the prevalence of dental trauma in patients with neuropsychomotor disorder and to compare to normoreactive individuals.

Material and method

120 individuals, 60 neuropsychomotor changes (study group) and 60 normorreatives (control group), of both sexes, from 2 to 15 years old, assisted in the Foundation of Support to the Disabled of the Government of the State of Paraíba. Data were collected through a structured questionnaire and clinical examination. Descriptive and inferential analysis (t-student test; Fisher's exact test) was performed, adopting a significance level of 5%.


The prevalence of dental trauma observed in patients with neuropsychomotor disorder was 20.0%, whereas in the control group it was 16.6% (p>0.05); in the control group the occurrence was higher in males. The groups differed according to the type of activity at the moment of the trauma (p<0.05) in relation to the etiology (p<0.05), and in relation to the place of occurrence (p<0.05). For both groups, the most affected teeth were the maxillary central incisors. Enamel fractures, followed by enamel and dentin fractures without pulp exposure were the most common lesions in both groups.


The prevalence of dental trauma in individuals with neuropsychomotor alterations is similar to that of normorreative individuals, with a higher occurrence in females, in preteen phase, during routine activities.
