Evaluation of Smile Line in Relation to Age among Saudi Population in Asser Region

Abstract

ABSTRACT Introduction Dentofacial appeal and smile are vital to a person's psychosocial well-being. The 'smile line’ is commonly used as a parameter to evaluate and categorize a person's smile. This study was undertaken to determine the parameters for an objective evaluation of smiles and to assess the prevalence of various smile determining parameters in relation to age among Saudi population in Asser region. Materials and methods A cross-sectional survey was designed. A total of 162 study samples participated in the study. A pre-designed proforma was used to evaluate malocclusion which consisted—demographic details, smile line, gingival line, incisal line, lower lip to incisal line, buccal corridor, facial midline and dental midline, shade for upper central incisors and shade for upper lateral incisors. Results The mean age of study participants were 27.07 ± 9.76 years. Majority of the participant, i.e. 52%, had average smile line and 9.3% had very high smile line. 64.8% of the study participants had normal gingival line. Only 2.5% had over, incisal line whereas 77.2 had normal incisal line. Majority (88.3%) of the participants had normal lower lip to incisal line. 44.4% had small buccal corridor. Conclusion There is scientific evidence that a certain smile line/tooth arrangement is the most common parameter which can be applied for treatment planning purposes. These results underline the importance of the smile line when restoring a patient's intraoral harmony. The clinician should aim for these parameters for an esthetic and functional balance.
