Quid is a mixture of substances that is placed in the mouth or actively chewed over an extended period, thus remaining in contact with the mucosa. It usually contains one or both of 2 basic ingredients, tobacco and areca nut. Betel quid or paan is a mixture of areca nut and slaked lime, to which tobacco can be added, all wrapped in a betel leaf. ⋯ The recognition of the role of such products in the development of oral precancer and cancer is of great importance to the dental practitioner. A variety of oral mucosal lesions and conditions have been reported in association with quid and tobacco use, and the association of these conditions with the development of oral cancer emphasizes the importance of education to limit the use of quid. In most cases, cessation of the habit produces improvement in mucosal lesions as well as in clinical symptoms.

Esthetic dentistry is among the most dynamic areas of contemporary clinical dentistry. Teaching programs in dental schools have a strong effect on the practice of dentistry, not only for recent graduates, but also for established clinicians, especially with respect to new techniques and concepts. The purpose of the study reported here was to assess the frequency and extent of the teaching of esthetic dentistry in North American dental schools and to report how it differs among the various schools. ⋯ The teaching of esthetic dentistry in North American dental schools is highly variable and in many schools is shared among different disciplines. Dental schools should work together to establish the parameters for teaching this subject and should formulate the necessary standards for education and research in this new field.
