Quantification of periodontal attachment at single-rooted teeth

Area of Science:

• Periodontology
• Biostatistics
• Dental Diagnostics

Background:

• Current methods for measuring periodontal attachment loss face challenges in clinical interpretation, measurement precision, and data analysis.
• Existing methodologies for assessing periodontal attachment loss have limitations impacting clinical decision-making and research.

Purpose of the Study:

• To propose an alternative measurement process for periodontal attachment loss.
• To estimate the lost attachment surface area (LAS) and remaining attachment surface area (RAS) using a combination of clinical measurements.

Main Methods:

• Developed linear combination models to predict RAS and LAS.
• Utilized bucco-lingual attachment level measurements, radiographic data (lost attachment area, tooth length, remaining attachment area), gingivitis index, and mobility index.
• Constructed models using anatomical landmark measurements to ensure accuracy.

Main Results:

• A diagnostic model for LAS achieved R2 = 81.5%, predicting the square root of LAS with high accuracy.
• The LAS model improved estimation precision by a factor of 1.86 compared to using only attachment level measurements.
• A diagnostic model for RAS achieved R2 = 75.5%, predicting the square root of RAS.

Conclusions:

• Periodontal data modeling offers a simple, cost-effective, and precise tool for predicting periodontal attachment loss and remaining attachment in single-rooted teeth.
• This novel measurement approach can enhance the evaluation of clinical decisions and research questions in periodontology.
• The proposed models address existing discrepancies between anatomical and clinical measurements, improving diagnostic reliability.
