To measure production of volatile sulfur compounds (VSC) responsible for halitosis on the crown surface of the maxillary fourth premolar of dogs with gingivitis.
28 dogs owned by veterinary students who complained that their dogs had halitosis.
Clinical dental indices (plaque index, calculus index, and gingival index) were measured on the most diseased maxillary fourth premolar tooth. Production of VSC from the crown surface of the tooth was recorded by use of a portable sulfide monitor. Measurements were performed several times on each dog over a 2-month period, resulting in 98 series of measurements.
Dogs with heavy amounts of plaque or calculus (plaque and calculus indices of 2 or 3) had significantly higher VSC readings than did dogs with no visible plaque and calculus accumulation. Significant (P = 0.0008) correlation was found between VSC measurements and plaque index, and significant correlations were found between VSC measurements and calculus index (P = 0.00118) and gingival index (P = 0.00475).
VSC production recorded on the crown of maxillary fourth premolar teeth of dogs with gingivitis is significantly correlated with the amount of plaque and calculus accumulation and with severity of gingivitis.
VSC measurements on tooth surfaces could be used as a site-specific method to assess, in conjunction with clinical dental variables, effectiveness of dental hygiene products.
测量患有牙龈炎的犬上颌第四前磨牙牙冠表面产生的导致口臭的挥发性硫化物（VSC）。
28只由兽医专业学生饲养的犬，这些学生抱怨他们的犬有口臭。
在患病最严重的上颌第四前磨牙上测量临床牙科指数（菌斑指数、牙石指数和牙龈指数）。使用便携式硫化物监测仪记录牙齿牙冠表面VSC的产生情况。在2个月的时间里对每只犬进行多次测量，共得到98组测量数据。
菌斑或牙石量较多（菌斑和牙石指数为2或3）的犬的VSC读数显著高于无可见菌斑和牙石堆积的犬。VSC测量值与菌斑指数之间存在显著相关性（P = 0.0008），VSC测量值与牙石指数（P = 0.00118）和牙龈指数（P = 0.00475）之间也存在显著相关性。
患有牙龈炎的犬上颌第四前磨牙牙冠表面记录的VSC产生量与菌斑和牙石堆积量以及牙龈炎的严重程度显著相关。
牙齿表面的VSC测量可作为一种特定部位的方法，结合临床牙科变量来评估口腔卫生产品的有效性。
