Summary
Dental age estimation in Brazilian children with Human Immunodeficiency Virus (HIV) shows slight overestimation using Willems
Area of Science:
- Pediatric Dentistry
- Radiology
- Infectious Diseases
Background:
- Human Immunodeficiency Virus (HIV) infection in Brazilian children, primarily vertical transmission, presents unique challenges.
- Many HIV-positive children face abandonment or loss of relatives, leading to uncertain identification and developmental monitoring.
- Accurate age assessment is crucial for managing pediatric HIV and other health conditions.
Purpose of the Study:
- To estimate the dental age of Brazilian children with HIV compared to healthy controls.
- To evaluate the applicability of Willems' method for dental age estimation in this population.
Main Methods:
- 160 panoramic radiographs from children aged 4-15 years (80 HIV-positive, 80 controls) were analyzed.
- Willems' method (2001) was used by three examiners to determine dental age.
- Intraclass Correlation Coefficient (ICC) and Student paired t-test were employed for statistical analysis.
Main Results:
- Willems' method showed a slight statistical overestimation of dental age in both HIV (2.86 months) and control (1.90 months) groups.
- Overestimation was more pronounced in males within both HIV (3.85 months) and control (2.86 months) groups.
- These statistical differences were not clinically significant, indicating high reliability.
Conclusions:
- Willems' method is a reliable tool for dental age estimation in Brazilian children, including those with HIV.
- The method demonstrates high reproducibility and clinical applicability despite minor statistical overestimations.
- Dental age estimation using Willems' method is recommended for both HIV-positive and healthy children with unknown chronological age.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
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...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
