Mesiodistal dimension of maxillary anterior teeth: their clinical implications

The size and form of the maxillary anterior teeth are important in achieving pleasing dental and facial esthetics1, 2 However, little scientific data have been defined as criteria for evaluating these. morphological features. Purpose of this study was to determine mesio-distal dimension of six maxillary anterior teeth at two different points i.e. from contact point to contact point and from mesio-labioincisal point angle to disto-labio-incisal point angle so that excellence in treatment can be achieved. Gypsum casts of 100 full dentate Pakistani adult [14-36 years] representing, with well aligned maxillary anterior teeth and minimal attrition were included in this study. Following conclusions were drawn: 1] Mesio-distal dimensions of six anterior maxillary teeth at two different areas i.e. measured from contact point to contact point [mesiodistal width of maxillary central incisors [R and L] 8.70+0.53 and 8.71+0.53 respectively, maxillary lateral incisors [R and L] 7.00+0.62 and 7.04+0.66 respectively and maxillary canine [R and L] 7.84+0.51 and 7.82+0.51] and measured from mesio-labio-incisal point angle to disto-labio-incisal point angle [mesiodistal width of maxillary central incisors [R and L] 8.10+0.52 and 8.10+0.53 respectively, maxillary lateral incisors [R and L] 6.46+0.61 and 6.53+0.62 respectively and maxillary canine [R and L] 6.97+0.48 and 6.95+0.52] respectively was established as an aid for appropriate diagnosis and treatment out come in different domains of dentistry. 2] Statistically significant correlation existed for each pair between right side anterior maxillary teeth and left side anterior maxillary teeth
