Presentation on theme: "Will my horse need to be sedated during a dental exam?"— Presentation transcript:
1Will my horse need to be sedated during a dental exam? Some horses find the process of having their mouth opened and instruments placed in the oral cavity to be stressful.For a complete oral examination and good quality corrective care, most horses benefit from a mild sedative to relieve any stress or unnecessary movement on the patient's part.When the horse is sedated, it allows us to do a better job in a safer way
2Dental Equipment Dental floats Extractors Periosteal elevator Forceps Wolf toothPremolars (cap)MolarsPeriosteal elevatorForcepsElectric dremmel
3Clean and SanitaryAll dental instruments, the speculum (device that holds the horse’s mouth open), buckets, etc are all cleaned and washed with an antimicrobial disinfectant (Nolvasan) between each and every horse. No exceptions!
4Diagnostic ImagingDentist should have access to diagnostic imaging equipment such as x-rays, preferably digital x-rays.This allows us to uncover and manage a host of equine dental abnormalities.
5What is the difference between traditional floating and power floating? Traditionally, horses have had their sharp enamel points and dental crown elongations reduced with hand-held rasps (floats).These manual dental instruments have improved in quality over the past 20 years but still require a reasonable amount of manual dexterity, physical strength and "elbow grease.”High quality dental tools powered by electricity or compressed air have become readily available and affordable over the past 10 years. These instruments reduce the physical effort that is required, and with expertise and caution, allow for more complete and efficient dental care.
6Common Dental Procedures Dental Equilibration - “Floating” to remove enamel pointsExtract wolf teeth.Reduce hooksReduce rampsCorrect unopposed teethCorrect overgrown teeth
7Dental Equilibration Removal of sharp enamel points Buccal surface – maxillary arcadeLingual surface – mandibular arcadeMost common procedure performed on adult (7 – 15 years of age) horses
8Equine Dentistry: “Floating” Technique Develop a sequential approach:Outside of upper arcadeInside of lower arcadeSeat float with short strokes.Lengthen strokes as float cuts into teeth.Maintain float handle parallel to occlusal surface.
11Wolf Tooth Extraction Indication: Vestigial, serve no purpose and may cause problemsHead tossingIrritation secondary to bit traumaBeginning training
12Wolf Tooth Extraction Procedure: Sedation Local anesthesia Loosen with periosteal elevatorExtract with small forcepsMay require rongeurs to remove broken root from below gum line
13Wolf Tooth Extraction Do not leave broken tooth root under gingiva. Choke the elevator to prevent laceration of the palatine artery.Should the palatine artery be lacerated-fold a towel, place into mouth, and tape shut for 30 minutes.
15Incisor reduction Correction of incisor misalignment Hand float Dremel toolMotorized raspImprove molar contact
16Canine Reduction Erupts between 4 – 6 years of age Reason for reducing caninesDisarm a horse with dental weaponsPrevents entrapping tongue between bit and toothPrevents ulceration of tonguePrevents damage to canine by horse, bit, etc..Prevents trauma to dentistPulp in young horses with 5-mm of crownReduce to level or just below occlusal surface of 06
17Molar/Premolar Reduction Reduction of excess clinical crownStep mouthSevere ramps and hooksWave mouthShear mouth
18“Bit Seat” Rounding of the rostral edge of 106/206 and 306/406 Smooth surface for cheek to rest with bit pressure
19Hooks/Ramps Excessive crown is greater in the vertical axis Result of mal-alignment of the mandibular and maxillary arcadesFunction of domestication
20Step Mouth Individual super-erupted tooth Usually un-apposed Missing apposing tooth
21Wave ComplexA series of super erupted teeth apposed by a series of excessively worn teethAge relatedWearing of the infundibular enamel
23Do donkeys and mules require different dental care than do horses? All equine species have the same type dentition.We see the same types of pathology and wear patterns in donkeys, mules, zebras and horses.Under current domestication practices, all require regular dental care.
