Clinical Periodontal Diagnosis: Probing

Periodontal pocketing, attachment loss, bone loss, and subgingival inflammation are among the clinical signs of periodontitis. Periodontal pockets and subgingival inflammation give evidence of actual periodontal infection, whereas attachment loss and bone loss are symptoms of former periodontitis that has caused tissue destruction in the past. Several clinical or radiographic methods are used t...

Diagnosis of Periodontal Diseases

cient and Practical Diagnosis

The task of diagnosis, a typical abductive problem, is to nd a hypothesis that best explains a set of observations. Generally, a neural network diagnostic reasoning model nds only one hypothesis to a set of observations. It is computationally expensive to nd the hypothesis because the number of the potential hypotheses is exponentially large. Recently, we have proposed a connectionist diagnosis...

Microbiological Diagnosis for Periodontal Diseases

Periodontitis, an infectious disease caused by bacteria, brings about destructive changes leading to loss of bone and connective tissue attachment (Williams, 1990). Several oral bacteria are considered to be possible pathogens in periodontitis (Darveau et al., 1997). In particular, the black-pigmented, Gram-negative anaerobic rods Porphyromonas gingivalis and Tannerella forsythia have been impl...
