The effect of three types of rasps on the occlusal surface of equine cheek teeth: a scanning electron microscopic study.
Abstract: Two hand rasps (tungsten chip blade, solid carbide blade) and an electrically-driven solid carbide axial bur were used to treat the cheek teeth of 2 horses immediately postmortem. All teeth were normal and were rasped to a standard considered satisfactory in practice. Six teeth from each horse served as untreated controls. Following treatment, the teeth were extracted and the clinical crown removed and prepared for scanning electron microscopy. Teeth were also extracted and examined from a horse that had excessive dental treatment previously. Dental debris created by the procedures was collected and examined. All three rasp techniques resulted in amputation of odontoblast processes. The solid carbide blade cut deep gouges and grooves into the surface of the dentin, chipping the enamel and peripheral cement. No smear layer was created. Rasping with a tungsten chip blade created a partial smear layer and a smoother surface than the solid carbide blade. The electrically-driven bur produced a complete smear layer and removed all dental tissues to a smooth layer. The enamel had also been damaged by the electric bur. Crown particles collected after the procedures were larger following hand rasping compared with particles produced by the electric bur. The extent of damage to sensitive and vital dentin tissue was of concern. Further studies are required to establish the optimum technique for rasping equine cheek teeth.

This study investigates the effect of different rasping tools on horses’ teeth. It finds substantial tooth and gum damage attributable to these procedures, asking for further research to find optimal techniques.
Objective
The study’s main objective was to evaluate and compare the impact of three types of rasps (two hand rasps and an electrically-driven bur) on the occlusal surface of equine cheek teeth. The teeth were examined postmortem, and after treatment, compared to untreated control teeth. The study also looked at dental debris produced by the procedures.
Methodology
- For the study, two hand rasps (tungsten chip blade, solid carbide blade) and one electrically-driven solid carbide axial bur were used on horse teeth immediately after they passed away.
- Each horse provided six treated teeth and six untreated control teeth, with the treatment aspiring to a standard considered satisfactory in veterinary practice.
- Post-treatment, the teeth were extracted, and the clinical crown removed, preparing it for a scanning electron microscopy examination.
Findings
- All three rasping techniques were found to disrupt odontoblast processes, which entails damage to the tooth’s structure.
- The solid carbide blade resulted in deep gouges and grooves in the dentin, as well as a chipping of the enamel and peripheral cement. No smear layer was created by this instrument.
- The tungsten chip blade rasp created a partial smear layer and produced a smoother surface compared to the solid carbide blade.
- The electrically-driven bur generated a complete smear layer and removed all dental tissues, leaving a smooth layer behind. However, enamel damage was observed in teeth treated with the electric bur.
- The debris produced by the procedures and collected after they were larger when hand rasping was used compared to the electric bur.
Concerns and Further Research
The authors expressed concern about the extent of damage to sensitive and vital dentin tissue caused by these rasping techniques. They called for additional investigations to establish the least harmful and most effective technique for rasping equine cheek teeth.
