abstract: BACKGROUND
  Rasping of sharp enamel points (SEPs) is the most common procedure performed at routine dental examinations; however, there is little evidence to prove the true clinical significance of SEPs [1]. Maxillary SEPs are thought to cause buccal ulceration and pain on external palpation of the cheeks. Mandibular SEPs are thought to cause lingual ulceration.
  
  
  OBJECTIVE
  To examine associations between the presence of SEPs on the cheek teeth rows and the presence of pain on palpation of the cheeks and buccal and/or lingual ulceration.
  
  
  METHODS
  Retrospective clinical case series.
  
  
  METHODS
  Clinical records of routine dental examination performed by 8 veterinary surgeons in a single first opinion practice were examined. Presence of SEPs, buccal and/or lingual ulceration and pain on palpation of the cheeks (externally) were recorded. Chi squared tests were used to examine whether horses exhibiting pain on palpation or oral ulceration were significantly more likely to have SEPs present.
  
  
  RESULTS
  Prevalence of buccal SEPs was 84.8% and prevalence of lingual SEPs was 84.3%. Five hundred and forty-eight horses (6.0%) had signs of pain on palpation. Prevalence of buccal ulceration was 5.9%. In contrast, only 0.2% of horses had visible lingual ulceration. Buccal ulceration and pain on palpation were significantly associated with presence of buccal SEPs (P<0.001 for both). Lingual ulceration was not significantly associated with lingual SEPs (P<0.0001).
  
  
  CONCLUSIONS
  Buccal SEPs are common and often result in pain and buccal ulceration. Routine rasping would appear to be justified. Lingual SEPs are common but rarely cause lingual ulceration. The value of routine rasping of lingual SEPs is therefore questionable.
