    Summary
    This summary is machine-generated.

    Ankylosis of primary molars affects 3.7% of children, with higher prevalence in white children. Early extraction is recommended for ankylosed primary teeth to manage potential growth issues.

    Area of Science:

    • Pediatric Dentistry
    • Dental Anthropology

    Background:

    • Ankylosis of primary teeth is a condition where the tooth root fuses with the alveolar bone, potentially impacting permanent tooth eruption.
    • Understanding the prevalence and patterns of primary molar ankylosis is crucial for timely diagnosis and intervention.

    Purpose of the Study:

    • To determine the prevalence of ankylosis in primary molars within a specific pediatric sample.
    • To investigate demographic variations (e.g., race) in ankylosis prevalence.
    • To identify specific primary molars and age groups most affected by ankylosis.

    Main Methods:

    • A cross-sectional examination of 2234 children was conducted.
    • Prevalence rates were calculated for ankylosis of primary molars.
    • Data were analyzed to compare prevalence across different racial groups and identify affected tooth types and age ranges.

    Main Results:

    • The overall prevalence of primary molar ankylosis was 3.7% (82 out of 2234 children).
    • Prevalence was significantly lower in black children (0.93%) compared to white children (4.10%).
    • The mandibular first primary molar was most frequently and earliest affected; ankylosis of the second primary molar increased with age, with a high incidence in children aged 7-11 years.

    Conclusions:

    • Primary molar ankylosis occurs in a notable percentage of children, with racial disparities observed.
    • The mandibular first primary molar is a common site, and prevalence increases with age for second primary molars.
    • Treatment strategies, including early extraction and space management, should consider the child's growth potential and the specific characteristics of the ankylosis.
