Collection description
OBJECTIVE: The aim of the study is to describe secular changes in mandibular growth comparing a historical group of non-treated subjects from AAOF legacy, used as control group in many cross-sectional studies on craniofacial skeletal growth, with a contemporary group of similar subjects. MATERIALS AND METHODS: The subjects group of historical controls from Bolton-Brush Growth Collection were matched for sex, age and race with subjects from a contemporary control group. Two examiners performed all of the cephalometric measurements at T0 and T1 (12 months later) according to Pancherz’s method using Dolphin Imaging 11.0 software. Data were analysed by conventional descriptive statistics. RESULTS: The mandibular increment in contemporary group is significantly higher than in the historical group (p=0.03). The dental values are also statistically higher in contemporary group, whilst for the other values there is not a significant increase. DISCUSSION: The results confirm the secular trends in craniofacial growth already described by other authors using anthropometry and cephalometric analysis. Add to this, there are some limitations in using the historical controls, resulting from difficulty to make a diagnosis of skeletal class II having only cephalometric data. CONCLUSIONS: An increased growth trend in contemporary subjects compared with historical controls is confirmed. The clinical trials using as controls individuals from historical collection could not have validity. There is need for further research to verify secular trends of growth on larger samples.
