To determine the incidence and rates of progression of gingivitis and periodontitis in Labrador retrievers.
Fifty-three dogs, aged 1·1 to 5·9 years, had their periodontal health assessed every 6 months for up to 2 years. The extent of gingivitis and periodontitis was measured around the whole gingival margin of every tooth under general anaesthesia.
All dogs had gingivitis at the initial assessment. The majority (64·2%) of tooth aspects had very mild gingivitis. The palatal/lingual aspect of all tooth types was most likely to show bleeding when probed: 63·0% of these aspects had mild or moderate gingivitis. Over 2 years, 56·6% of dogs developed periodontitis and dogs as young as 1·9 years were affected. There was a significant positive correlation between the proportion of teeth with periodontitis and age. In total, 124 teeth (5·7%) developed periodontitis; 88 (71·0%) of these were incisors. The palatal/lingual aspect of the incisors developed the disease first (2·8% of incisor aspects).
Periodontitis developed in regions that are difficult to see in conscious dogs implying that detection and treatment of disease requires periodic sedation or anaesthesia.
确定拉布拉多寻回犬牙龈炎和牙周炎的发病率及进展速率。
53只年龄在1.1至5.9岁的犬，每6个月进行一次牙周健康评估，为期2年。在全身麻醉下，测量每颗牙齿整个牙龈边缘周围的牙龈炎和牙周炎程度。
所有犬在初次评估时均患有牙龈炎。大多数（64.2%）牙齿部位患有非常轻微的牙龈炎。所有牙型的腭侧/舌侧在探诊时最容易出血：其中63.0% 的部位患有轻度或中度牙龈炎。在2年时间里，56.6% 的犬患上了牙周炎，年仅1.9岁的犬也受到了影响。患有牙周炎的牙齿比例与年龄之间存在显著正相关。共有124颗牙齿（5.7%）患上了牙周炎；其中88颗（71.0%）为切牙。切牙的腭侧/舌侧最先发病（占切牙部位的2.8%）。
牙周炎发生在清醒犬难以看到的区域,这意味着疾病的检测和治疗需要定期镇静或麻醉。
