IntroductionThe knowledge of anterior tooth width and their relationships with each other is essential for any esthetic and prosthodontic rehabilitation. The objective of this study is to measure the width of the anterior teeth of patients coming to a teritary hospital of Nepal.MethodsThis descriptive cross-sectional study was conducted at a tertiary care hospital from 30th September 2019 to 30th October 2019 after receiving ethical clearance from the institutional review committee (reference number: 2076/77/20). Convenient sampling was done. Point estimate at 99% Confidence Interval was calculated along with frequency and proportion for binary data. Data analysis was done in Statistical Package for the Social Sciences version 21.ResultsOut of the 40 participants, the mean width of right and left side of anterior teeth of the maxillary central incisors were 8.62±0.62 mm and 8.65±0.55 mm; maxillary lateral incisors were 6.97±0.74 mm and 7.11±0.78 mm; maxillary canine were 7.81±0.69 mm and 8.15±0.72 mm; mandibular central incisors were 5.37±0.4 mm and 5.43±0.37 mm; mandibular lateral incisors were 5.88±.52 mm and 6.06±0.53 mm; mandibular canine were 6.69±0.55 mm and 6.93±0.7 mm respectively. The difference between the teeth was compared with the central incisors of each side.ConclusionsOur findings of the average values of the anterior teeth and their difference from the central incisors on each side showed an agreement with the optimal relationships of anterior teeth, with the exception of the maxillary lateral incisors, which were 0.5mm larger than the values of the optimal relationship.
