A new equine peripheral caries grading system: Are the caries likely active or inactive?

This research article presents a proposed grading system for assessing equine peripheral caries to assist clinicians in evaluating the condition, categorizing it as likely active or inactive and determining the need for intervention.

Objective of the Research

• The main goal of this study was to test the reliability of a new alternative grading method for equine peripheral caries composed of three systems: the traditional grading system, a new research grading system, and a new clinical grading system.

Research Methodology

• An online survey was carried out among veterinary surgeons who then graded images of peripheral caries using the three grading systems.
• The consistency in grading and agreement among the participants on the severity of caries was analyzed using a statistical measure known as Fleiss’ kappa and the percentage agreement.

Results of the Study

• All percentage agreements and Fleiss’ kappa values were significantly greater than zero, indicating a high level of agreement among graders.
• The Fleiss’ kappa for the new methods ranged from 0.48 to 0.58, which was higher than the traditional method (0.40), but the difference was not significant.
• There was a high level of consistency in the assessment of caries as either active or inactive, with both grading systems showing over 80% agreement.
• Over 90% of reviewers stated that they were likely to use the new grading system, indicative of a positive feedback.

Conclusions Drawn

• There were some difficulties in using photographs due to image quality and the challenge in judging if the dentin had been affected without an occlusal image of the teeth.
• Despite these, the new grading system still provided a consistent estimate of caries severity and offered high levels of agreement as to whether the caries were likely active or inactive. This makes it a promising tool to aid practitioners in deciding whether intervention is necessary.

In conclusion, this research proposes an alternative method to the traditional grading system for equine peripheral caries that not only estimates the severity of the caries but also provides valuable information on their current state as either active or inactive. This could assist clinicians in formulating better-informed management and treatment plans for affected horses.
