摘要:

Intraoral transmission radiographshave been the primary diagnostic method for the assessment of bone support as well as for the detection and measurement of osseous changes due to periodontitis. The purpose of the present paper is three‐fold. The first is to review radiographic techniques for the assessment of periodontal disease progression, presenting the strengths and weaknesses of each method while placing special emphasis on digital subtraction radiography. The second purpose is to present data from a recent study that compared the ability of digital subtraction radiography and automated attachment level probing to detect the same active sites. Thirty periodontitis patients and eight control patients were studied over a 6‐month period. The results indicate that when these two sensitive methods for the assessment of progressive periodontitis were used there was concordance between the presence or absence of probing attachment loss and bone loss in 82.1% of the sites. The final goal of this paper is to present future directions for the quantitative analysis of digital radiographic images.J Periodontol 1992; 63:367– 372.

摘要:

Physical measurements including the evaluationof probing depth, bleeding on probing, tooth mobility, and inflammation form the basis for most periodontal diagnostics in use today. The interpretation of these observations and the methods available for their measurement, however, have begun to change significantly. The episodic disease activity concept has done much to implement these changes. Observation of episodic attachment loss has been correlated with parallel radiographic changes, alteration in levels of probable pathogens, and changes in inflammatory mediator levels. The failure of pocket depth, suppuration, and bleeding on probing to predict episodic attachment loss has been given plausible explanations and enhanced meanings. Although attachment loss by a continuous process cannot be excluded in some disease conditions, the hypothesis of periodontal disease progression by episodic activity supplements and expands understanding of the disease process. Interest in periodontal diagnostics has accelerated in the last decade. As a parallel development, the technology of small computers has decreased in cost and increased in sophistication. The combination of these factors has created an environment for the development of intelligent diagnostic systems. Four commercially available systems and two systems under development are described. The systems, which measure pocket depth, pocket depth or attachment level, tooth mobility, and pocket temperature, all utilize computer processing of measurements. The result is to provide a simplified and more meaningful presentation of diagnostic information. As intelligent diagnostic systems prove themselves, some of these instruments are likely to become common to dental practice. The promise of more accurate identification of areas of the mouth that are diseased can increase both the efficiency and effectiveness of periodontal therapy. J Periodontol 1992; 63:373–382.

摘要:

New diagnostic technologiesmay be capable of providing the dental practitioner with powerful tools that can assist in the early identification of periodontal disease that can result in expediated treatment. In this paper, clinical, host, and microbiological parameters will be evaluated for their ability to assess disease activity and to assist in the treatment decision‐making process. The discussion will focus on: 1) the perceived need for markers of disease activity; 2) the most commonly proposed markers of disease activity currently under consideration for clinical application; and 3) a plan for future use of disease activity markers. The review concludes that: 1) tooth loss and most forms of rapid disease progression is limited to a small subset of patients within the periodontally diseased population; 2) no single parameter will stand alone as a measure of disease activity; 3) different aspects of treatment may require different combinations of tests to successfully intercept disease in this vulnerable patient group; and 4) early diagnosis can affect long‐term periodontal status. Best estimates are presented for: 1) pre‐disease identification of high‐risk population groups; 2) early diagnosis of disease activity on a site and patient basis; and 3) assistance in the therapeutic decision‐making process. It is further concluded that the complexity of the problem may require a re‐examination of priorities such that more time and money is allocated to early diagnosis as opposed to treatment in this highly vulnerable patient population.J Periodontal 1992; 63:383‐393.
