Maxillary Incisors of the Horse before and at the Beginning of the Teeth Shedding: Radiographic and CT Study.

Abstract: To gain insight into the radiographic appearance of maxillary deciduous incisors and dental germs of maxillary permanent incisors in the period prior to teeth shedding, radiographs and computed tomography (CT) of 25 horse skulls, with an estimated age of between 12 and 42 months, were studied. Data regarding morphology and development were obtained. Dental germs of first maxillary permanent incisors were identified radiographically as rounded radiolucent areas at the level of the apical parts of the first deciduous incisors, in skulls with an estimated age of twelve months. The first sign of crown mineralization of these dental germs appeared in skulls supposedly a few months older. Before teeth shedding, the unerupted, mineralized crowns of the first permanent incisor could be identified radiographically relatively caudal to the corresponding first deciduous incisors. The results of the present study indicate that radiographic intraoral images are suitable to identify the grade of development of the dental germs of maxillary permanent incisors. A detailed description of the radiographic appearance of deciduous incisors and dental germs of permanent incisors will help clinicians to expand their knowledge for diagnostic or treatment purposes.

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 study examines the radiographic and CT imaging of baby teeth and the incoming adult teeth in the upper jaw of young horses to better understand tooth development and morphology during the teeth shedding process.

Methodology

  • Investigation involved the use of both radiographs and computed tomography (CT) scans on 25 horse skulls. These horses were estimated to be between 12 and 42 months old.
  • The team was specifically looking to study the change in appearance of maxillary deciduous incisors (baby teeth) and the dental germs of maxillary permanent incisors (new, developing adult teeth) during the period before teeth shedding.

Findings

  • The researchers found that dental germs of the upcoming adult teeth appeared as rounded, radiolucent (area appearing dark on radiographs) at the level of the apical (lower) parts of the first baby teeth on the skulls of horses that were approximately twelve months old.
  • Signs of mineralization, or hardening, of the crowns of the dental germs was evident a few months later. These unerupted, mineralized crowns of the first adult tooth could be identified radiographically, positioned towards the back of the corresponding baby tooth.

Implications

  • This study suggests that radiographic intraoral (inside the mouth) images can serve as suitable tools for identifying the stage of development of permanent incisors in horses.
  • The detailed description of the radiographic appearance of baby and adult teeth before shedding should expand clinicians’ knowledge, aiding in diagnostic and treatment purposes. This is especially useful in veterinary dentistry for horses, which may involve treatments like extraction of deciduous teeth, detection of dental abnormalities, or orthodontic cases.
