RESUMEN
OBJECTIVE: To characterize the stomatognathic system of individuals with Treacher Collins syndrome (TCS) by assessing bite force (BF) and masticatory performance (MP) and to evaluate the nutritional status (NS) of this population through anthropometric measurements. DESIGN: Cross-sectional study. SETTING: A public tertiary care hospital. PATIENTS: Forty-one individuals were divided into 2 groups: (1) Control (CON): 20 control adults with class I skeletal pattern and (2) TCS: 21 adults with TCS. INTERVENTIONS: BF measurement was assessed using a gnathodynamometer (IDDK Kratos). MP assessment was done using Image J-NIH software, by calculating the particles size of food submitted to standard chewing cycles ). NS was assessed based on body mass index (BMI). MAIN OUTCOME MEASURES: Based on the craniofacial dysmorphology, it is our hypothesis that this population present a dysfunctional masticatory system, which can negatively impact NS. RESULTS: Means BF values for the TCS were significantly reduced when compared with the CON group and corresponded to 170.9 ± 109.4N and 431.6 ± 134.1N (right molar [RM]) and 171.2 ± 93.9N and 427.4 ± 147.8N (left molar [LM]), respectively (P < .05). Although no significant differences were observed, the mean particle size of the TCS was greater when compared with the CON group and corresponded to 1.58 ± 1.93â mm2 and 0.66 ± 0.52â mm2, respectively. Although statistically similar mean values of BMIs were observed on both groups (CON = 23.4 ± 4.7/TCS = 23.4 ± 6.1), underweight and overweight individuals were found in 48% of the individuals with TCS and in 15% of the CON group participants. CONCLUSION: Individuals with TCS showed a significant BF reduction, but no differences were observed in MP and NS when compared with the control individuals.
RESUMEN
OBJECTIVES: To relate nutritional status with food acceptance by patients undergoing alveolar bone grafting and to elaborate an interdisciplinary instrument for data collection, involving nutrition and nursing teams. DESIGN/INTERVENTION: A prospective, longitudinal, and comparative study with a quantitative approach was conducted in a tertiary institutional hospital. The nutritional anthropometric evaluation was performed one day before surgery (M1) and at hospital discharge (M2), by measuring body mass index (BMI), triceps skinfold thickness (TST), subscapular skinfold thickness (SST), and arm muscle circumference (AMC). The interdisciplinary instrument for data collection was used. PATIENTS: The sample comprised 150 patients, aged 10 to 20 years, of both genders, who agreed to participate in this study. RESULTS: Most of patients were well-nourished during the study. There was correlation between BMI and Σ TST + SST at M1 and M2 (P < .0001) and between BMI and AMC (P < .0001). Concerning food acceptance, 145 patients had adequate intake and 5 did not. Comparisons between the groups of patients revealed decreases in values for BMI, Σ TST + SST, and AMC from -0.37, 0.0, and 0.3, respectively, at M1 to -0.71, -3.0, and 0.0, respectively, at M2. BMI and AMC showed similar decreases in both groups. CONCLUSIONS: The interdisciplinary instrument was useful and appropriate for associating nutritional status with food acceptance, adding value for teamwork.
