The bleeding tendency and fear of bleed may have a negative effect on preventive dental care of patients with hemophilia both at home and at dental office. A review of literature regarding the care of hemophilic patients showed the paucity of material on this important subject, and the lack of information on the dental health of this group of patients. Aim: To evaluate the oral hygiene status, prevalence of dental caries and treatment needs of children with haemophilia Materials and Methods: A descriptive cross -sectional study was conducted on 328 subjects with age ranging from 5-15 years attending and registering their names, residential address, parental occupation and other criteria in hemophilic society at Telangana state and Andhra Pradesh state.

Teeth affected by dental caries and teeth restored/extracted as sequale of dental caries were assessed using decayed, missed, filled tooth (DEFT), DMFT for primary and permanent dentition respectively. Statistical analysis: student t test. Results: The mean oral hygiene index simplified scores were 3.21 in 5-10 years and 3.22 in 11-15 years respectively. The mean deft of 5-10 years was 3.23 and for 11-15 years was 2.27 and DMFT for 5-10 years was 2.81 and highest mean DMFT 5.92 was recorded in 11-15 years age group.
