Dimensions of periodontal tissues are thought to predispose to the development of periodontal disease in man and dogs. Several studies have suggested that thin gingiva correlates with an increased incidence of periodontal disease. In this study, we hypothesized that the dimensions of periodontal tissues will vary in different breeds of dogs and could possibly correlate with the incidence of periodontal disease. Forty-two jaws of dogs aged up to 5-years were examined post-mortem and gingival and alveolar bone thickness were measured using methods of transgingival probing and digital calipers, respectively. Dogs were divided into three groups based on their body weight. Group I (< 5.0 kg; n=21), group II (5 to 10 kg; n=11), and group III (10 to 15 kg; n=10). Thickness of gingiva ranged from 0.30-mm to 3.2-mm and was relatively thinner in group I than in group II and III based on the means of ratios comparison. Alveolar bone thickness ranged from 0.27-mm to 4.1-mm and was relatively thinner in group I compared with groups II and III. Our study showed significantly thinner gingiva and alveolar bone in toy breed dogs compared with small and medium-sized breed dogs. Both gingival and alveolar bone dimensions may be predictors for severity of periodontal disease and influence clinical outcome in certain periodontal surgical procedures.

An endosseous implant is described as osseointegrated when it is immobile in function. Objective measures of stability testing have been described. The Periotest is a commercially available device that is used for this purpose. This study was designed to measure stability of endosseous implants placed in the mandible. Implants were placed in the mandibular canine or first premolar area to support an overdenture prosthesis. Stability was evaluated through the use of a Periotest device at the time of implant placement and following one year of functional loading. Implant designs were either a screw-shaped titanium alloy or a hydroxyapatite-coated cylinder. A total of 54 implants were placed, 37 were titanium screw-shaped implants, while the remaining 17 were hydroxyapatite cylinders. Initial measurements of stability showed no difference due to implant type. Following one year of functional loading, titanium screw-shaped implants were more stable than hydroxyapatite implants (P < 0.05). The difference in implant rigidity following a period of functional loading may be an indication of a difference in osseointegration between the two implants used in this study.
