Gingival inflammation at deciduous and permanent teeth. An intra-individual comparison

Area of Science:

• Pediatric Dentistry
• Periodontology
• Oral Health Research

Background:

• Previous research indicated differing gingivitis tendencies between deciduous and permanent dentition in children and dogs.
• Juvenile dogs exhibited protective morphologic characteristics in their junctional epithelium.
• Understanding human gingival differences between deciduous and permanent teeth requires studying reactions to controlled plaque levels.

Purpose of the Study:

• To conduct an intra-individual comparison of gingival reactions to plaque in children with mixed dentition.
• To determine if structural differences in human gingiva between deciduous and permanent teeth have clinical significance regarding gingivitis.

Main Methods:

• Study involved 30 children aged 7-9 years with mixed dentition.
• Plaque levels were assessed using the plaque index.
• Gingival inflammation was measured using the gingival index.

Main Results:

• No significant differences in mean gingival index scores were observed between deciduous and permanent teeth.
• A higher percentage of plaque index scores 2+3 was found on permanent teeth.
• Areas with similar plaque irritation showed a tendency towards higher gingivitis degrees at deciduous teeth.

Conclusions:

• Structural differences, if present, between gingiva at deciduous and permanent teeth lack clinical significance in the gingivitis response.
• The findings suggest that age-related gingival tissue variations do not substantially alter inflammation susceptibility in children.
