Abstract Consideration of the age factor in dentogenics provides a means for intelligent, as well as artistic, correlation of the physiologic and chronologic life lines in the edentulous patient. No longer can it be acceptable to place dentures in patients' mouths which have no identity with the patients' general age structure. The dignity of advancing age must be appropriately portrayed in the denture by careful tooth color selection and by mold refinement; also by the intervention of such characterization as would be fitting for the personality and sex of the patient. Very often, we have observed people in advanced years with dentures displaying a complement of teeth which would seldom be found in the natural dentition of a teenager. This is thoughtlessness, and it is not only embarrassing to the patient but reflects very unfavorably upon the dental profession. The positioning of the teeth in the denture base is the beginning in age interpretation, and it will be found that the subtle nuances of early age significance is usually more difficult to achieve than the imperfections associated with increasing age. The diastema so appropriate in the older interpretation must be used very judiciously in the more youthful interpretation. It should be kept in mind that the qualities of age are present in the natural teeth as well as in other tissues of the body, and we must create the illusion of age to a satisfactorily artistic sense in our artificial substances. The matrix in which the teeth are invested is a very important means of expressing the quality of age. Not only is this possible by the use of color in the matrix, but, even more important, by particular attention to the interdental papillae as to shape, length, and breadth. These are the subtle but powerful nuances at the command of the observing dentist.
