Clinicians must be very careful when making clinical evaluations of the need for crown lengthening procedures and margin placement and subsequent determinations about the dento-gingival junction and biologic width. Clinicians have tried to standardize a biologic phenomenon and assign the same standard to all patients regardless of the circumstances.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

D000539	Alveolar Process	The thickest and spongiest part of the maxilla and mandible hollowed out into deep cavities for the teeth.	Alveolar Ridge,Alveolar Processes,Process, Alveolar,Processes, Alveolar,Ridge, Alveolar
D016556	Crown Lengthening	Technique combining controlled eruptive TOOTH MOVEMENT TECHNIQUES and incision of the supracrestal gingival attachment to allow for proper restoration of a destroyed or damaged crown of a tooth. Controlled eruption of the tooth is obtained using ORTHODONTIC APPLIANCES. During this eruptive phase, repeated incisions are made at the junctional epithelium of the sulcus and the supracrestal connective tissue to prevent coronal displacement of the gingiva and of the attachment apparatus.	Lengthening, Crown
D019228	Tooth Crown	The upper part of the tooth, which joins the lower part of the tooth (TOOTH ROOT) at the cervix (TOOTH CERVIX) at a line called the cementoenamel junction. The entire surface of the crown is covered with enamel which is thicker at the extremity and becomes progressively thinner toward the cervix.

D019237	Tooth Cervix	The constricted part of the tooth at the junction of the crown and root or roots. It is often referred to as the cementoenamel junction (CEJ), the line at which the cementum covering the root of a tooth and the enamel of the tooth meet.
