The dental changes in MPS population are high and consequently it is important to know them for differential diagnoses, early treatment intervention, prevention and education of both patients and parents/caregivers about oral health.

This epidemiologic survey aimed at assessing the prevalence of traumatic dental injuries in children seen at the Federal University of Rio de Janeiro, Brazil. The records of a total of 111 children (aged 0 to 6 years) seen from 2004 to 2006 in the dental trauma clinic were surveyed, comprising a total of 201 traumatized primary teeth. Data pertaining to the child and to the trauma such as age, gender, etiology, teeth involved, type of traumatic injury, time elapsed between the trauma and seeking care, and the presence and kind of clinical and radiographic sequelae in the first visit were collected from the dental records. All variables studied were assessed by means of frequency analysis and the Chi-square test (p < 0.05). A higher prevalence of trauma was observed in boys (56.7%) and in the age group from 0-3 years (73.8%). The most affected teeth were the central incisors (84.7%) and the most common trauma etiology was a fall from the child's own height (63.0%). The supporting tissues were the most affected. Lateral luxation was the most frequent alteration observed (33.4%), followed by concussion (21.0%). Coronal discoloration (17.7%) and external resorption (18.3%) were, respectively, the most prevalent clinical and radiographic sequelae. Gender had no influence on the clinical (p = 0.54) and radiographic (p = 0.55) sequelae. Even though age had no influence on radiographic sequelae (p = 0.41), clinical sequelae were more prevalent in children aged 0 to 3 years (p = 0.03). In conclusion, traumatisms in primary teeth were more prevalent in boys, and in 0-3-year-old children. Luxation was the most frequent traumatic lesion, and coronal discoloration and external resorption were the most prevalent sequelae.

This study aimed to assess the responsiveness of the Brazilian version of the Parental-Caregiver Perception Questionnaire (B-P-CPQ) to describe changes in quality of life (QoL) after treatment for traumatic dental injury (TDI). After eligibility criteria were applied, 42 of 255 patients who went to a dental trauma center for TDI treatment were included. QoL was evaluated in two different appointments: A1 (after TDI) and A2 (after TDI treatment). The B-P-CPQ scores were calculated using the additive method. Psychometric properties like internal consistency (Cronbach's Alpha), test-retest reliability, intraclass correlation coefficient (ICC), and construct validity (Spearman's correlations) were assessed, and, mainly, the responsiveness was analyzed by standardized response means (SRM). Mean B-P-CPQ scores were 30.05 (1.74 SD) and 2.67 (4.05 SD), while the median scores were 17.39 and 2.00 (P < 0.01), respectively in A1 and A2. Cronbach's Alpha was 0.87 in A1 and 0.66 in A2. ICC was 0.90. B-P-CPQ scores were correlated with overall well-being (P < 0.01; rho: 0.71). The B-P-CPQ responsiveness scores declined 27.38 points, and a perfect SRM of 1.76 was achieved. The B-P-CPQ scores indicated changes in QoL following TDI. The change was observed as an impact decrease after TDI treatment, demonstrating positive reduction and improvement on QoL. The responsiveness of the P-CPQ (Brazilian version) in detecting change on QoL after TDI treatment was confirmed by SRM assessment. The findings represent an evidence of the importance of professional care and treatment of TDI.

One can observe a relationship between traumatic dental injury and its impact on quality-of-life. Children and adolescents who suffered traumatic dental injury showed negative experiences and greater functional and emotional impact.
