Anterior Tooth Width Measurements among Patients in a Tertiary Hospital of Nepal: A Descriptive Cross-sectional Study
Introduction: The 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.
Methods: This 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.
Results: Out 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.
Conclusions: Our 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
