The research team will aim to elucidate more information on the role of genetics in the development of the physiognomy of the face. Equally as important will be the effects of the environmental factors on maxillo-facial development. It should help us to become more knowledgeable about the interface of the individual parts of the face of the child along the development course of becoming an adult face. Normative data will be developed to give much needed facial growth standards on American Blacks to serve as a guide to orthodontics, plastic surgeons, maxillo-facial surgeons, pedodontists and other physicians, dentists and health care professionals treating American Blacks. The study will quantify the similarities of the morphology on the facial region of the two ethnic groups in the United States, i.e. Blacks and Whites. It will also identify the differences in the physiognomy of the face of the two groups. A three dimensional study of the development and eruption of third molars will be done on a longitudinal basis. It should be the first three dimensional longitudinal study of third molar eruption and impaction. It should set standards that will allow clinicians to scientifically determine when to extract third molars and when to leave them in place. This study will further elucidate the role played by genetics in the development of malocclusions and the role played by the environment. It should determine the types of malocclusions that can be prevented and those that will require corrective surgery. The data will be digitized and computerized. This study will further enhance the use of computers in orthodontic diagnosis and treatment planning. It should improve on the preventive aspects of treatment of the oral and facial structures to improve on function and for cosmetic purposes. It should further reduce the amount of needless surgery being done to extract third molars.

研究小组将致力于阐明更多关于 遗传学在面部相貌发育中的作用。等同于 重要的是环境因素对 颌面部发育。它应该帮助我们变得更有见识 关于儿童面部个别部位的界面沿途 成人面孔的发展历程。规范的数据将是 旨在为美国黑人提供亟需的面部发育标准 作为正畸、整形外科医生、颌面外科医生的指南 外科医生、小儿科医生和其他内科医生、牙医和保健 治疗美国黑人的专业人士。这项研究将量化 两个民族面部形态的相似性 在美国的群体，即黑人和白人。它还将确定 两组患者面部相貌的差异。A三 第三磨牙发育和萌出的维度研究将是 在纵向的基础上完成。它应该是第一个三维的 第三磨牙萌出和阻生的纵向研究。它应该设置为 将允许临床医生科学地确定何时 拔除第三颗磨牙，以及何时将其保留到位。这项研究将 进一步阐明遗传学在人类发育过程中所起的作用 错(牙合)和环境所起的作用。它应该确定 可以预防的错合类型和将要预防的错合类型 需要做矫正手术。这些数据将被数字化和计算机化。 这项研究将进一步加强计算机在正畸中的使用 诊断和治疗计划。它应该在预防的基础上有所改进 口腔和面部结构的治疗需要改进的方面 功能和美容用途。它应该会进一步减少 为拔掉第三颗磨牙做了不必要的手术。
