Early Primary Tooth Loss: Prevalence, Consequence and Treatment

Resumen

The aim of this study was to perform an epidemiological survey of the prevalence of early  primary tooth loss (EPTL) as a result of caries lesion, as well as the consequences and the treatment proposed in a Brazilian population. A study was conducted  with a total of 446 dental records containing the panoramic radiograph of children from 5 to 12 years (8.0 years ± 1.5). For statistic analysis Chi-square test (p<0.05) was used. One hundred twenty-nine  children (28.9%) had EPTL, either by premature loss or indication of tooth extraction as a consequence of caries  lesions. There was no significant difference between genders (p=0.53) in EPTL. Among the children that presented absence of at least one dental element affected, 52 (96%) had erupted permanent first molar and 20 (37%) presented loss of space and impaction of the successor tooth. Sixty-three children had indication for space maintanence. The prevalence of EPTL, as well as orthodontic treatment was high in this population. These findings suggested that there is an immediate need for educational and preventive programs related to caries.
