Comparison of the Mesio-Distal Widths of the Maxillary and Mandibular Central Incisors Between Cleft Lip and Palate and Non Cleft Lip and Palate Individuals
Keywords:Cleft lip and palate, tooth abnormalities, tooth size discrepancy
Objective: To compare the mesiodistal widths of the maxillary and mandibular central incisors of cleft lip and palate individuals with non-cleft individuals, in a local population.
Methodology: A total of 80 casts (40 of cleft patients and 40 normal) were selected by the department of orthodontics from January, 2021 to February, 2022, dividing them it into 4 groups by consecutive non-probability technique. The mesiodistal width of the maxillary and mandibular central incisors was measured with vernier caliper. Independent t test was applied to compare the mesiodistal width of maxillary and mandibular central incisors between normal and cleft patients. Descriptive statistics were calculated for all four groups.
Results: The mean MD width for the maxillary central incisors was 6.58 ± 1.16mm and 7.67 ±1.18mm for the CLP and control group respectively. The mean MD width for the mandibular central incisors was 4.22± 0.91 mm and 4.67 ± 0.9 mm for the CLP and control group respectively. The student t test showed a significant difference in the MD width of both the maxillary and mandibular central incisors between the CLP and control group.
Conclusion: Patients suffering from cleft lip and palate are associated with diminutive central incisors in both jaws.
