Summary
This study proposes a periodontal treatment model using remaining bone support to achieve a bone height of one-third root length by age 75. It analyzes radiographic data to predict bone loss and identify intervention points for maintaining periodontal health.
Area of Science:
- Dentistry
- Periodontology
- Radiology
Background:
- Periodontal disease leads to alveolar bone loss, impacting long-term tooth retention.
- Predictive models are crucial for timely periodontal treatment decisions.
- Establishing treatment goals based on bone support is essential for patient prognosis.
Purpose of the Study:
- To develop a tentative model for periodontal treatment decision-making.
- To define a target for remaining alveolar bone height by age 75.
- To establish criteria for therapeutic intervention based on bone loss rates.
Main Methods:
- Analysis of longitudinal intraoral radiographs from 194 dentate individuals (aged 25-70).
- Measurement of alveolar bone levels at mesial and distal tooth sites over approximately 10 years.
- Calculation of longitudinal bone level changes and determination of a rate factor for bone loss prediction.
Main Results:
- Described alteration in alveolar bone height per 5-year interval between ages 25 and 75.
- Determined a rate factor for each tooth site based on mean bone loss data.
- Defined specific alveolar bone levels at which therapeutic intervention is recommended to meet the study's goal.
Conclusions:
- The developed model provides a framework for proactive periodontal treatment planning.
- Maintaining one-third root length of alveolar bone by age 75 is presented as a feasible treatment objective.
- The model's applicability in clinical decision-making for periodontal therapy is discussed.
