Effects of traumatic XXXX to primary teeth on permanent teeth--a clinical follow-up study.

@entity1 @entity8495 @entity509 @entity74 @entity130
AIM: This study evaluated the prevalence of developmental sequelae to permanent teeth (DSP) after traumatic @entity8495 to primary teeth (TDI-1) and their association with age, gender, @entity130 , recurrence of injury and post-traumatic damage to primary teeth. MATERIALS AND METHODS: Dental records of 2725 @entity1 treated from February 1993 to December 2008 in a private pediatric dental clinic were examined. A total of 308 records had 412 primary teeth that sustained @entity130 . Age at the time of injury ranged from 4 months to 7 years. A chi-squared test and logistic regression were used for statistical analyses. RESULTS: One hundred forty-eight @entity1 (241 teeth) were followed up until the eruption of the permanent successor. The prevalence of DSP was 22.4%. Discoloration and @entity509 were the most frequent abnormalities (74.1%), followed by @entity74 (25.9%). Age at the time of TDI-1 was the only variable significantly associated with DSP. Sequelae were most prevalent among @entity1 who suffered an injury between 1 and 3 years of age. CONCLUSIONS: @entity1 who sustain traumatic @entity8495 should be followed up regularly for an early diagnosis and treatment of possible DSP.
