Manual versus reciprocating endodontic debridement of equine cheek teeth: Micro-computed tomography findings.

Abstract: In orthograde endodontic treatments, different methods are available to debride the pulp canals of endodontically compromised equine cheek teeth, but their efficacy is unknown. Objective: To explore and compare the efficacy and anatomical changes caused by manual versus reciprocating filing techniques in equine cheek teeth, to explore the presence of instrumentation mishaps described in human dentistry and to explore anatomical complexities of the pulp cavity that often remain uninstrumented using microcomputed tomography (μCT). Methods: Ex-vivo randomised experiments. Methods: Twenty-two extracted healthy equine cheek teeth were randomised into two groups: debridement with nickel-titanium (Ni-Ti) manual H-files and debridement with Ni-Ti reciprocating K-files. All canals of all teeth were instrumented by a single clinician and μCT scans made before and after instrumentation were digitally analysed to compare the change in pulp volume, loss of dental material, percentages of instrumented pulp canal wall at three levels, instrumentation times and instrumentation mishaps between both techniques. The data were analysed using either an Independent samples T-test or Mann-Whitney U-test with p < 0.05 denoting a statistically significant difference. Results: The use of reciprocating files resulted in a statistically significant advantage at apical levels when it comes to the percentage of instrumented root canal surface (p < 0.01; reciprocating mean 12% ± 6; manual mean 3% ± 3). No other significant differences were found between the methods. Instrumentation mishaps were detected in this study and were equally distributed between the two groups. Frequently uninstrumented regions consisted of intercanal communications, root canal branches, narrow corners of pulp canals and branches of pulp horns. Conclusions: Convenience sample, use of healthy cheek teeth, ex vivo debridement. Conclusions: The debridement efficacy in equine cheek teeth is generally poor with a slight apical advantage using reciprocating instruments. Instrumentation mishaps should be kept in mind when performing endodontic procedures in the equine patient.

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.

This research article investigates and compares the debridement (cleaning) efficiency of two methods – manual H-files and reciprocating K-files – in treating endodontically compromised equine cheek teeth. The study evaluates the changes brought about by these techniques in the tooth’s anatomy and identifies common errors and uninstrumented areas.

Methodology

  • The researchers conduct ex-vivo experiments on 22 healthy equine cheek teeth, extracted for the study. These teeth are divided into two groups: one group is treated with manual H-files, and the other group is treated with reciprocating K-files. Both these instruments are made from nickel-titanium (Ni-Ti).
  • A single clinician conducts the instrumentation process for all tooth canals, and microcomputed tomography (μCT) scans are used to analyse the pre and post instrumentation condition of the teeth.
  • The parameters observed and compared include changes in pulp volume, loss of dental material, the percentage of instrumented pulp canal wall at three levels, instrumentation times, and errors during instrumentation.
  • Statistical analysis is performed using the Independent samples T-test or Mann-Whitney U-test, and any result with p < 0.05 is considered as a statistically significant difference.

Results

  • The use of reciprocating K-files shows a considerable advantage at the root canal’s apical levels, where it was able to debride a higher percentage of the root canal’s surface.
  • However, the study does not show any other significant difference between the two techniques.
  • Errors during instrumentation were observed in the study and were evenly spread out between the two groups. Frequently uninstrumented areas included intercanal communications, root canal branches, narrow corners of pulp canals and branches of pulp horns.

Conclusion

  • The study concludes that while both debridement methods for treating equine cheek teeth have similar efficiencies, reciprocating instruments provide a slight advantage when operating at the apical levels of the root canal.
  • The researchers also urge clinicians to be cautious of possible errors while performing endodontic procedures in horses, based on the observation of instrumentation mishaps in the study.
