Summary

Children with deciduous teeth formed less plaque and gingivitis compared to those with mixed or permanent dentition over a 7-day period without oral hygiene. This highlights age-related differences in plaque formation and gingival response.

Area of Science:

  • Oral health research
  • Periodontology
  • Pediatric dentistry

Background:

  • Dental plaque accumulation is a primary factor in gingival inflammation.
  • Understanding plaque formation and gingival response across different dentition stages is crucial for oral hygiene strategies.

Purpose of the Study:

  • To investigate de novo plaque formation and gingival changes in deciduous, mixed, and permanent dentitions.
  • To compare plaque accumulation and gingivitis development in different age groups over a 7-day period without oral hygiene.

Main Methods:

  • 31 volunteers were divided into three groups based on dentition: deciduous (4-6 years), mixed (8-9 years), and permanent (14-16 years).
  • Participants received oral hygiene instruction and professional cleaning, then abstained from mechanical oral hygiene for 7 days.

  • Plaque and gingivitis assessments were conducted at baseline, and after 3 and 7 days.

    • Main Results:

    • Subjects with mixed or permanent dentition showed visible plaque and mild gingivitis after 7 days without hygiene.
    • Younger subjects with deciduous dentition formed less plaque and exhibited minimal gingivitis.
    • Plaque formation and gingivitis development were similar in deciduous and permanent teeth within the mixed dentition group.

    Conclusions:

    • Age and dentition stage significantly influence de novo plaque formation and gingival inflammation.
    • Children with deciduous teeth demonstrate a reduced capacity for plaque accumulation and gingival response.
    • Findings suggest tailored oral hygiene approaches may be beneficial across different developmental stages of dentition.
