OBJECTIVE
To assess the prevalence of periodontal disease, orofacial changes and craniofacial abnormalities in patients with thalassemia major (TM). Dental management is discussed
METHODS
The sample consisted of 54 patients with TM, 31 males and 23 females aged 5.5 to 18.3 years, with the mean age (+/- SD) of 1.6 +/- 3.2 years. The sample was divided into two subgroups according to age. A similar number of unaffected control group matched by age and sex served as a control. Clinical and radiographic examinations were carried out to assess the prevalence of changes caused by this disorder. Student's t-test was used to compare the means between thalassemic group and the control group. The Chi-square test was employed to determine statistical differences in frequencies between the two groups.
RESULTS
Poor oral hygiene and gingivitis were observed in 61.1% and 43.0% of the thalassemic patients, respectively. The overall mean plaque score was 1.66 +/- 0.51 and gingival score 1.43 +/- 0.59. In all tested periodontal parameters, a higher frequency and severity were noted in the thalassemic patients compared with controls. More than half of the patients exhibited frontal bossing, saddle nose and to less extent maxillary protrusion; giving in severe cases (16.7%) a "chipmunk" like appearance. Dental discoloration and pallor oral mucosa were noted in 44.4% and 38.9%, respectively. Dental/jaw pain was reported by 40.0% and headache by 29.6% of the patients. Increased overjet was evident in 25.9% of the patients. The majority of the patients had thickened frontal bone (66.7%), and thinned inferior border of the mandible (64.6%). Widened dipolic spaces and spiky roots and were observed in one-third of the patients. The ramus length and width in the patients were significantly smaller than in controls (P < 0.001).
CONCLUSIONS
TM may particularly diagnose through orofacial abnormalities. Dentists required understanding the complications and management of the disease.
