Labial Gingival Recessions And The Post Treatment Proclination Of Mandibular Incisors

Area of Science:

• Dentistry
• Periodontology
• Orthodontics

Background:

• Labial gingival recession, characterized by apical migration of the gingival margin, affects dental aesthetics and health.
• Mandibular incisor proclination post-orthodontic treatment is a potential factor in gingival recession development.
• Understanding this relationship is crucial for clinical strategies to minimize periodontal complications.

Purpose of the Study:

• To evaluate the relationship between mandibular incisor proclination and the emergence of labial gingival recession.
• To investigate the impact of incisor inclination on periodontal health following orthodontic treatment.

Main Methods:

• A prospective cohort study involving 180 participants followed for one year.
• Assessments included clinical crown height measurements, gingival recession presence, and cephalometric analysis of incisor inclination.
• Participants were grouped based on post-treatment incisor inclination (<95°, 95°-100.5°, >100.5°), with focus on non-proclined (<95°) and proclined (>100.5°) groups.

Main Results:

• Mean increase in clinical crown heights for lower incisors post-treatment varied between the proclined (0.58-1.32 mm) and non-proclined (0.64-0.89 mm) groups.
• No statistically significant difference in the elevation of clinical crown heights was observed between the non-proclined and proclined groups.
• Gingival recession occurrence did not significantly differ between groups.

Conclusions:

• Mandibular incisor inclination does not elevate the risk of gingival recession.
• No significant association was found between post-treatment incisor proclination and gingival recession over a five-year period.
