Oral health indices predict individualised recall interval

Area of Science:

• Dentistry
• Public Health
• Epidemiology

Background:

• The individualised recall interval (IRI) is a key component of routine oral health examinations.
• Determining appropriate recall intervals is crucial for effective dental care management and resource allocation.

Purpose of the Study:

• To investigate the association between common oral health indices and the length of the IRI in an adult population.
• To understand how measures of dental caries and periodontal disease influence recall interval recommendations.

Main Methods:

• An observational, register-based study analyzed data from 42,533 adults undergoing oral health examinations.
• Oral health was assessed using DMFT (decayed, missing, filled teeth), DT (decayed teeth), and CPI (Community Periodontal Index).
• Recall intervals were categorized, and their association with oral health indices was modeled using a proportional odds model.

Main Results:

• Higher scores for DMFT, DT, and CPI were significantly associated with shorter recall intervals.
• The number of teeth present was not a relevant predictor of recall interval length.
• The severity of periodontal disease (indicated by CPI) strongly predicted shorter recall intervals, independent of other demographic and health factors.

Conclusions:

• Oral health indices, particularly those reflecting caries and periodontal disease, are strong predictors of individualised recall intervals.
• Poor oral health necessitates shorter recall intervals, guiding dental organizations in preventive care planning.
• These findings underscore the utility of oral health indices in tailoring recall strategies for optimal patient outcomes.
