Abstract
The aims of this cross-sectional study were to investigate prevalence of dental caries and occlusion and
analyse the association between medical parameters and dental caries and occlusion in thalassemic pediatric
patients one hundreds and nine subjects at Pediatric OPD, Srinagarind Hospital, Faculty of Medicine, Khon Kaen
University. Medical information of the patient were recorded. Each patient was examined dental caries and
occlusion by one dentist. Results showed that mean dmft was 3.75±3.41, 7.58±4.49 and 0.64±1.95 for ages 0-<5,
5-<10 and more than 10 years old. The DMFT values were 1.87±1.98 and 5.83±4.01 for ages 5-<10 and more
than 10 years old, respectively. Convex profile were the most prevalence of profile in thalassemic patients
(82.6%). Present malocclusion were the most prevalence of occlusion (85.4%). Age at onset transfusion therapy
was significantly associated with malocclusion (P= 0.012). In conclusion, medical parameters are associated with
occlusion in Thailand pediatric patients.
