Background
Complications, especially delayed alveolar healing,
are common following equine cheek teeth extraction,
however, limited objective information is available on
the prevalence and nature of these problems.
Objectives
To document the type and prevalence of complications
that occur following equine cheek tooth extraction and
to identify possible risk factors for these complications
that could be used to predict their occurrence and
hopefully reduce their prevalence.
Study design
Retrospective cohort study.
Methods
Clinical records of all cheek teeth extractions performed
between February 2004 and September 2018 were
examined and written questionnaires sent to owners.
Details of post‐extraction complications were analysed
and logistic regression was used to evaluate potential
associations between the likelihood of post‐extraction
nonhealing alveolus managed by the authors and the
variables: age, breed, reason for extraction, Triadan
position and extraction technique.
Results
Post‐extraction complications were recorded following
58/428 extractions giving an overall complication rate
of 13.6%, that caused a longer term clinical problem
in 34/428 (7.9%) cases, with complications being
asymptomatic or quickly self‐resolving in the other
24 cases (5.6%). The most frequent complication was
alveolar bone sequestration, including alveolar infection.
Risk of developing a post‐extraction alveolar disorder
managed by the authors (n = 53) increased following
extraction of the mandibular 06s, 07s or 08s compared
with all other cheek teeth combined (P = .001); for cheek
teeth with apical infections (P = .002) compared with
those without; and following repulsion or minimally
invasive transbuccal extraction (MTE) than following
oral extraction (P = .01 and P = .02 respectively).
Main limitations
Length of time between exodontia and survey data
collection for some cases, use of clinical records and
survey data and biases associated with decision to treat.
Conclusions
In agreement with previous studies, oral extraction had
the lowest risk of complications. This study provides
new information regarding the prevalence, types and
risk of development of post extraction complications.
Knowledge of these risk factors may help reduce these
complications.
