Summary
Equine cheek tooth extraction complications, like delayed healing, occur in 13.6% of cases. Risk factors include specific tooth positions and extraction methods, but oral extraction shows the lowest complication rate.
Area of Science:
- Veterinary Medicine
- Equine Dentistry
- Surgical Complications
Background:
- Delayed alveolar healing is a frequent complication after equine cheek tooth extraction.
- Objective data on the prevalence and characteristics of these complications are limited.
Purpose of the Study:
- To determine the types and prevalence of complications following equine cheek tooth extraction.
- To identify potential risk factors for predicting and reducing these complications.
Main Methods:
- Retrospective cohort study analyzing clinical records from February 2004 to September 2018.
- Owner questionnaires were used to gather post-extraction complication data.
- Logistic regression evaluated associations between complications and factors like age, breed, tooth position, and extraction technique.
Main Results:
- An overall complication rate of 13.6% (58/428 extractions) was observed, with 7.9% causing long-term issues.
- Alveolar bone sequestration and infection were the most common complications.
- Increased risk of complications was associated with mandibular 06-08 extractions, pre-existing apical infections, and repulsion/minimally invasive transbuccal extraction (MTE) compared to oral extraction.
Conclusions:
- Oral extraction demonstrated the lowest risk of complications, consistent with previous research.
- This study provides novel insights into the prevalence, types, and risk factors for post-extraction complications.
- Understanding these risk factors can aid in mitigating complication rates in equine dental surgery.
