Tooth loss in 1535 treated periodontal patients

Area of Science:

• Periodontology
• Dental Implantology

Background:

• Long-term outcomes of periodontal disease treatment are crucial for patient prognosis.
• Understanding tooth loss patterns post-treatment informs clinical decision-making.

Observation:

• A study surveyed 1535 patients an average of 12.9 years after periodontal treatment.
• 1371 patients (89.4%) experienced no tooth loss due to periodontal disease.
• Average tooth loss was 0.29 per patient, totaling 444 teeth lost.

Findings:

• Full arch splinted cases showed a significantly higher tooth loss rate (14.67 teeth/patient).
• 73.5% of patients required surgical procedures during initial treatment.
• Recurrent periodontal issues necessitated surgical retreatment in 15.9% of patients.

Implications:

• Periodontal treatment demonstrates high success rates in preserving teeth long-term.
• Patients with initially doubtful prognoses are at higher risk for recurrent problems and extraction.
• Further research comparing different surgical pocket therapy procedures is warranted.
