Intra-pulp temperature increase of equine cheek teeth during treatment with motorized grinding systems: influence of grinding head position and rotational speed.

Abstract: In equine practice, teeth corrections by means of motorized grinding systems are standard procedure. The heat resulting from that treatment may cause irreparable damage to the dental pulp. It has been shown that a 5.5°C temperature rise may cause severe destruction in pulp cells. Hence, the capability to continuously form secondary dentine is lost, and may lead, due to equine-typical occlusal tooth abrasion, to an opening of the pulp cavity.To obtain reliable data on the intra-pulp increase in temperature during corrective treatments, equine cheek teeth (CT) were modified in a way (occlusal surface smoothed, apical parts detached, pulp horns standardized) that had been qualified in own former published studies. All parameters influencing the grinding process were standardized (force applied, initial temperatures, dimensions of pulp horns, positioning of grinding disk, rotational speed). During grinding experiments, imitating real dental treatments, the time span for an intra-pulp temperature increase of 5.5°C was determined. Results: The minimum time recorded for an intra-pulp temperature increase of 5.5°C was 38 s in mandibular CT (buccal grinding, 12,000 rpm) and 70 s in maxillary CT (flat occlusal grinding, 12,000 rpm). The data obtained showed that doubling the rotational speed of the disk results in halving the time span after which the critical intra-pulp temperature increase in maxillary CT is reached. For mandibular CT, the time span even drops by two thirds. Conclusions: The use of standardized hypsodont CT enabled comparative studies of intra-pulp heating during the grinding of occlusal tooth surfaces using different tools and techniques. The anatomical structure of the natural vital hypsodont tooth must be kept in mind, so that the findings of this study do not create a deceptive sense of security with regard to the time-dependent heating of the native pulp.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research focuses on examining how temperature increases within the pulp of equine (horse) teeth during dental correction procedures, specifically those using motorized grinding systems. The study establishes the time it takes for a critical temperature increase, which can cause irreparable damage, to occur in different conditions.

Methodology

  • A set of equine cheek teeth was modified for the experiment.
  • The variables that might influence the grinding process were substantiated. These included the force used, the initial temperatures, dimensions of the pulp horns, the positioning of the grinder, and its rotational speed.
  • During grinding experiments, replicating real dental treatments, the time it took for an intra-pulp temperature increase of 5.5 °C was established.

Results

  • The briefest time recorded for an intra-pulp temperature increase of 5.5 °C was 38 seconds in lower teeth (buccal grinding at 12,000 rpm) and 70 seconds in upper teeth (flat occlusal grinding at 12,000 rpm).
  • The data showcased that doubling the rotational speed of the disk reduced the time after which the critical intra-pulp temperature increase is met by half in upper teeth. For lower teeth, the time span lessened by two-thirds.

Conclusion

  • This study allowed for a comparative analysis of intra-pulp heating during the grinding of occlusal tooth surfaces using different tools and techniques.
  • The researchers caution that despite these findings, the complex anatomical structure of horse teeth should always be considered to avoid a misleading sense of safety about the time-dependent heating of the native pulp.
