Quantitative cytomorphometric analysis of exfoliated normal gingival cells

Area of Science:

• Oral exfoliative cytology
• Biomarkers in oral health
• Quantitative cytology

Background:

• Oral exfoliative cytology is crucial for diagnosing oral abnormalities.
• Establishing a baseline for normal oral tissue is essential for comparison.
• Understanding variations in normal cells aids in detecting pathological changes.

Purpose of the Study:

• To determine age and sex-related changes in nuclear area (NA), cytoplasmic area (CA), and nuclear:cytoplasmic ratio (N:C ratio) in healthy gingival smears.
• To establish a baseline for quantitative cytological parameters in a healthy population.

Main Methods:

• Collected gingival smears from 80 healthy individuals (40 male, 40 female) across four age groups.
• Utilized Papanicolaou staining and image analysis software for measuring NA and CA.
• Performed statistical analysis using ANOVA and Student's t-test to assess differences.

Main Results:

• Significant age-related differences in NA, CA, and N:C ratio were observed in both males and females (P<0.001).
• Significant sex-related differences in NA, CA, and N:C ratio were found across all age groups (P<0.001).
• Overall age irrespective of gender showed significant differences in NA, CA, and N:C (P<0.05).

Conclusions:

• Age and sex significantly influence cytomorphometric parameters in normal gingival cells.
• These findings provide a crucial baseline for interpreting cytological changes in oral premalignant and malignant lesions.
• Quantitative analysis of gingival smears can reveal subtle alterations related to demographic factors.
