Alveolar bone loss in patients with long-term supportive care

Area of Science:

• Dentistry
• Periodontology
• Radiology

Background:

• Periodontitis is a chronic inflammatory disease affecting the gums and supporting bone.
• Long-term management is crucial for preventing further disease progression and tooth loss.
• Dental school clinics provide a setting for studying treatment outcomes over extended periods.

Purpose of the Study:

• To assess the long-term radiographic progression of alveolar bone loss in periodontitis patients treated and maintained in dental school clinics.
• To evaluate the rate of bone loss over an average of 14.9 years.
• To determine if disease progression correlates with specific anatomical sites or recall frequencies.

Main Methods:

• Retrospective audit of radiographic records from 63 periodontitis patients treated for ≥10 years.
• Analysis of bite-wing radiographs from 50 patients, with assessments spanning 8 to 34 years.
• Calculation of mean annual bone loss rates and comparison across different sites (maxillary/mandibular, molar/premolar, mesial/distal).

Main Results:

• The mean annual rate of alveolar bone loss was 0.037 mm.
• No significant differences in bone loss were observed between different anatomical sites.
• The observed bone loss is comparable to findings in other published studies.

Conclusions:

• Long-term treatment and maintenance of periodontitis patients in dental school settings result in minimal radiographic evidence of disease progression.
• Regular recall and maintenance are effective in controlling alveolar bone loss.
• The findings support the efficacy of current periodontitis management protocols.
