Factors associated with the survival of primary maxillary anterior teeth after intrusive luxation: a retrospective longitudinal study

PURPOSE

To evaluate the survival rate of primary maxillary anterior teeth following intrusive luxation and identify associated factors.

METHODS

A retrospective longitudinal study was conducted at a primary dental trauma centre using 88 dental records of children with intrusive luxation between 2007 and 2018. The variables of interest were time the tooth remained in the alveolus, degree of intrusion, accentuated overjet, lip protection, visible plaque, compromised germ of the permanent successor, clinical signs of infectious and inflammatory processes, endodontic treatment, pulp canal obliteration, sex, age at the time of trauma, family income, mother's schooling, and immediate care. Descriptive, bivariate, and Cox regression analyses were performed (p < 0.05; 95% CI).

RESULTS

The 88 dental records of children with intrusive luxation included 128 teeth. Survival rate throughout the follow-up period was 65.6% (n = 84). Age older than three years and eight months (HR 2.28; 95% CI 1.04-4.99; p = 0.039), the development of an infectious process (HR 3.51; 95% CI 1.39-8.86; p = 0.008), development of an inflammatory process (HR 2.35; 95% CI 1.17-4.71; p = 0.016) and compromised germ of the permanent successor (HR 4.38; 95% CI 1.99-9.61; p < 0.001) were associated with a lower survival rate of intruded primary maxillary anterior teeth.

CONCLUSION

The survival rate during the follow-up period of intruded primary maxillary anterior teeth was considered high. A significantly lower survival rate was associated with age, the occurrence of an infectious process and inflammatory process, and the compromised germ of the permanent successor.

Impact of untreated dental caries and dental pain on sadness related to oral health of Brazilian children

PURPOSE

Children should feel sad when they believe that a negative outcome is permanent. The sadness that an oral problem might bring tends to contribute to children's loneliness and increase the social stress levels. The aim of this study was to evaluate the impact of untreated dental caries, dental pain, malocclusion, and traumatic dental injury on prevalence of sadness related to oral health among Brazilian children.

METHODS

This cross-sectional study was carried out with 397 children aged 8-10 years randomly selected from public and private schools in Diamantina, Brazil. The Brazilian version of the CPQ_8-10 was applied. Sadness was collected through the question, "In the last month how often did you feel sad because of your teeth or mouth?" and dental pain through the question, "In the last month, how many times have you had pain in your teeth?" One calibrated examiner (Kappa value intra examiner: 0.77-0.91; Kappa value inter examiner: 0.80-1.00) performed the exam for dental caries (DMFT), malocclusion (DAI), and dental trauma (O'Brien). Parents answered questions addressing socioeconomic issues. Descriptive analyses, Chi-square test, and hierarchical Poisson regression models were performed (IC 95%; p < 0.05)."

RESULTS

The prevalence of sadness related to oral health was 30.5% (n = 121). Sadness related to oral health was associated with untreated dental caries (PR: 1.46; 95% CI 1.32-2.46; p = 0.001 ) and dental pain (PR: 2.91; 95% CI 2.00-4.22; p < 0.001). Other clinical variables analyzed (traumatic dental injury and malocclusion) were not significantly associated with sadness related to oral health.

CONCLUSIONS

Children with untreated dental caries and dental pain presented a higher report of sadness related to oral health.
