NEW PERSPECTIVE FOR EVALUATION OF TOOTH WIDTHS IN PATIENTS WITH MISSING OR PEG-SHAPED MAXILLARY LATERAL INCISORS: QUADRANT ANALYSIS

Objective: To compare the mesiodistal widths of teeth having missing lateral or peg lateral with the control side and control set of dentition. Materials and Methods: This cross sectional study was carried out at Khyber college of dentistry from January 2019 to April 2019. 60 individuals were selected 24 males and 36 females were selected. The mesiodistal width of teeth in quardarants having missing lateral incisors or having peg shape lateral were included and compared with the control set of dentition, consective sampling technique was used using SPSS version 22. Results: maxillary central incisor shows statistically non-significant difference in the mesiodistal width as compared with the control groups of having mesiodistal width of 8.5mm. canine shows statistically significant difference in mesiodistal width when compare with the control groups of having mesiodistal width of 7.5mm. premolars and molars also shows statistically significant difference in mesiodistal widths when compared with the control groups of having mesiodistal width 7mm and 10mm, respectively. Conclusion:in Patients having missing or peg shape lateral incisor the mesiodistal width of the dentition is narrower than the control subjects so in quadarant analysis will be more helpful in determining treatment stratagies as compared to the conventional tooth analysis method.
