RESUMEN
Periodontal disease in dogs is highly prevalent but can only be accurately diagnosed by performing an anesthetized oral examination with periodontal probing and dental radiography. In this study, 114 dogs had a visual awake examination of the oral cavity and were administered an oral-fluid thiol-detection test prior to undergoing a a full-mouth anesthetized oral examination and digital dental radiographs. The results show the visual awake examination underestimated the presence and severity of active periodontal disease. The thiol-detection test was superior to the visual awake examination at detecting the presence and severity of active periodontal disease and was an indicator of progression toward alveolar bone loss. The thiol-detection test detected active periodontal disease at early stages of development, before any visual cues were present, indicating the need for intervention to prevent periodontal bone loss. Early detection is important because without intervention, dogs with gingivitis (active periodontal disease) progress to irreversible periodontal bone loss (stage 2+). As suggested in the current AAHA guidelines, a thiol-detection test administered in conjunction with the visual awake examination during routine wellness examinations facilitates veterinarian-client communication and mitigates under-diagnosis of periodontal disease and underutilization of dental services. The thiol-detection test can be used to monitor the periodontal health status of the conscious patient during follow-up examinations based on disease severity.

This study evaluated a novel test strip designed to assess thiol levels as they relate to gingival/periodontal health in dogs. The simple to use strip (similar in form to a pH test strip) provides a colorimetric signal which estimates the level of thiols dissolved in oral fluid. Among several oral sites tested (left and right lingual vestibules, lower buccal vestibule, and upper buccal gingival margin), fluid from the maxillary gingival margin gave results with the best dynamic range, and its thiol levels correlated well with several oral health parameters (Pearson coefficients between 0.55 and 0.84; P < 0.001), especially those relating directly to the gingiva. The strip, which can be used on animals which are awake, may be useful as a quick, objective assessment of periodontal health, potentially enhancing compliance for thorough examinations, and promoting earlier and better-sustained treatment programs.
Évaluation pilote d'un nouveau bâtonnet diagnostique pour l'évaluation des taux de thiol dissous comme indicateur de la santé gingivale canine et de la situation parodontale. Cette étude a évalué un nouveau bâtonnet diagnostique conçu pour évaluer les taux de thiol tels qu'ils se rapportent à la santé gingivale et parodontale des chiens. Le bâtonnet facile à utiliser (de forme semblable à un bâtonnet diagnostique de pH) fournit un signal colorimétrique qui estime le taux de thiols dissous dans le liquide buccal. Parmi plusieurs sites buccaux testés (vestibules linguaux gauche et droit, vestibule buccal inférieur et bord marginal de la gencive buccale supérieure), le liquide du bord marginal de la gencive maxillaire a donné les résultats avec le meilleur écart dynamique et ses taux de thiol correspondaient bien à plusieurs paramètres de la santé buccale (coefficients de Pearson entre 0,55 et 0,84; P < 0,001), particulièrement ceux se rapportant directement à la gencive. Le bâtonnet, qui peut être utilisé sur les animaux lorsqu'ils sont éveillés, pourra être utile comme évaluation objective rapide de la santé parodontale, ce qui rehaussera potentiellement l'observance pour des examens complets et fera la promotion de programmes de traitement mieux soutenus qui sont administrés plus tôt.(Traduit par Isabelle Vallières).
