Despite improvements in materials and preventive efforts, orthodontic treatment continues to carry the considerable risk of enamel demineralization. Each patient's prophylactic efforts, including fluoride use, are of paramount importance in preventing WSLs.
The oral hygiene regimens in Germany and Poland were not comparable, as more plaque was found in the Polish than in the German population. Plaque accumulation seems not to be a key factor in causing periodontal destruction in the cleft area. Factors other than oral hygiene should be considered of major importance in relation to the development of gingival recession on teeth in cleft areas.
This new technique of symmetry analysis reveals that the noses of 10-year-old patients with complete unilateral cleft lip and palate who had not undergone revisional surgery present a measurable and significant degree of asymmetry, while the upper lip is symmetrical as a consequence of interdisciplinary treatment by orthodontists and oral and maxillofacial surgeons. Further 3D analyses on larger numbers of patients will allow more comprehensive and consistent analysis of the potential and limitations of various surgical and conservative methods so as to identify those techniques with the best outcome in terms of facial symmetry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
