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.

Family Impact Scale (FIS): psychometric properties of the Brazilian Portuguese language version.

AIM: Evaluate the psychometric properties of the Brazilian version of the Family Impact Scale (FIS). METHODS: Following translation and cross-cultural adaptation, the FIS was tested on 123 parents-caregivers of children between 11 and 14 years of age with dental caries and malocclusions. The parents were recruited from the Paediatric Dental and Orthodontic clinics where their children were receiving dental care. Psychometric properties were assessed through internal consistency, test-retest reliability, construct validity and discriminant validity. RESULTS: The mean FIS score was 6.97 (SD 7.81) for the dental caries group and 7.25 (SD 7.70) for the malocclusion group. The FIS score was unable to discriminate different family impact caused by children's oral health conditions. Internal consistency was confirmed by a Cronbach's alpha coefficient of 0.79. Test-retest reliability revealed good reproducibility (ICC 0.83). Construct validity was good, demonstrating highly significant correlations between parent's perceptions regarding the overall wellbeing indicator for their children and the total FIS and subscales. Financial burden demonstrated no significant correlation with global indicators. CONCLUSIONS: Overall psychometric results for the Brazilian version of the FIS confirm it as a reliable, valid questionnaire for assessing the family impact caused by children's oral conditions.
