Introduction:
Bleeding disorders are certainly one of the most difficult health conditions among health professionals. The haemophilia requires special care in dentistry mainly due to highly vascularized oral cavity.
Aim:
The objective of this study was to determine oral health conditions of children and adolescents with haemophilia at a haematology centre.
Methods:
The sample was composed of 40 children and adolescents aged 1-18 years. Data collection occurred by means of a questionnaire about social and economical conditions, and an examination of the oral cavity. The decayed, missing and filled deciduous teeth (dmft), decayed, missing and filled permanent teeth (DMFT) and gingival bleeding (allows the determination of gingival bleeding) epidemiological indexes were evaluated.
Results:
When evaluating caries experience, the mean value for the dmft index was 3.4 for the deciduous dentition, DMFT score of 0.9 for mixed-dentition, and 2.9 for permanent dentition. The mean value for the gingival bleeding index was similar in all three phases of development, showing a mean value of 1.74.
Conclusion:
The majority of the children and adolescents demonstrated unsatisfactory oral health.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
