| Summary: | Objective: This study was carried out to determine the prevalence of microdontia among patients undergoing orthodontic treatment.
Materials and Methods: This was a cross-sectional study conducted at Sindh Institute of Oral Health Sciences, Jinnah Sindh Medical
University (JSMU) from January-2020 to May-2020. Pre-treatment casts were taken of 140 subjects. The mesiodistal dimension of each
tooth was recorded through the vernier caliper. Frequency and percentage were calculated for the presence of microdontia. The test
applied was Pearson’s Chi-square test to assess the relationship between microdontia and variables like age and gender. P-value <0.05
was taken as statistically significant. Data analysis was performed on SPSS version 22.
Results: A total of 140 subjects were selected i.e. 105 (75%) females and 35 (25%) males with the age range 13-30 years and mean age
of 18.29 ± 3.88 years. 42(30%) subjects presented with microdontia. Out of 42, single tooth microdontia was found in 3 (7.1%), more than
one tooth microdontia, and generalized microdontia was present in 36 (85.7%) and 3 (7.1%) respectively. Microdontia was found to be
more common in the maxilla (n=42, 100%) than the mandible (n=14, 33.3%). It was found more common in females (n=37, 35.2%) as
compared to males (n=5, 14.3%). Statistically significant relationship was found among gender and prevalence of microdontia (p=0.019)
with a statistically insignificant relationship between age and presence of microdontia (p=0.228).
Conclusion: Microdontia was found to be a frequent dental anomaly, was more common in maxilla and females with a significant
association with gender |
