One study has demonstrated that at least one furcation of maxillary first or second molars is affected by the periodontal disease in 50% of all patients over 30 years of age 7. Category Definition very good <25% attachment loss good 25% attachment loss and/or class I furcation involvement >75% attachment loss, class III mobility. New attachment can occur to the cementum of both non-vital and vital teeth. Initial stage should be determined using clinical attachment loss (CAL). However, it must be remembered that deep pockets can have a better prognosis if the bone levels are adequate and the bone defects present are amenable for regenerative therapy. T ooth loss for 100 treated periodontal patients (2,509 teeth) under maintenance care was evaluated to determine the effectiveness of commonly taught clinical parameters utilized in the assignment of prognosis in accurately predicting tooth survival. Just like many other diseases, the earlier it is found and treated, the better the prognosis is. As a review, the periodontal classifications were revised in 1999 and classified as chronic, aggressive (localized and generalized), necrotizing, and a manifestation of systemic disease. (adsbygoogle = window.adsbygoogle || []).push({}); Individual tooth prognosis referrers to the prognosis of an individual tooth, based on local and prosthetic/restorative factors that have a direct effect on its prognosis. The broad occlusal surface is a bad prognostic factor as it may cause increased tooth mobility. References are available in the hard-copy of the website. Very Good Good Fair Poor Hopeless. Previous studies in this series evaluated prognosis as a surrogate variable representing the condition of the tooth at a particular point. Presence/absence of occlusal interferences. I. The AAP states that clinical attachment loss (CAL) should be used to initially stage periodontal disease, but, if not available, then radiographic bone loss can be used in its place. In patients with slow disease progression, the prognosis of teeth is always better than those with rapid disease progression. Various studies have demonstrated that the actual success of the treatment does not depend on the execution of the treatment but on the patient’s adherence to the oral hygiene regimen and cooperation with the dental team 30, 31. The periodontal status of the tooth is influenced by local and/or systemic factors that cannot be controlled. A review of the literature by Kinane (1997) 22 found considerable evidence to suggest that diabetes and periodontitis have a direct relationship. However, this is a crude method for the determination of prognosis because there are various other factors such as root length, root form, root shape, single or multiple roots etc., which also have to be considered while determining the prognosis. Journal of dental education. Methods . Hughes FJ, Syed M, Koshy B, Marinho V, Bostanci N, McKay IJ, Curtis MA, Croucher RE, Marcenes W. Prognostic factors in the treatment of generalized aggressive periodontitis: I. It also refers to the determination of whether the prosthesis to be planned shall be therapeutic or detrimental. A classification for gingivitis and periodontitis has been proposed based on clinical observations and immunologic parameters (summarized in Table 10). Retrospective study of tooth loss in 92 treated periodontal patients. Systemic conditions, like uncontrolled diabetes mellitus, are associated with poor periodontal prognosis. 5. Usually, patients commonly ask questions like, for how many years my teeth will be all right after this treatment? %���� <> The initial periodontal treatment can be well executed by a general dentist, but a strict referral protocol should be employed when advanced periodontal treatment is required. For example, the maxillary first premolars show increased tooth mobility because these have conical and tapered roots. Periodontal Prognosis Friday, January 16, 2015 1:00 PM Exam 2 Page 1 ... McGuire Nunn Classification - based on tooth loss. It has been demonstrated by various studies (see chapter 35), that traumatic occlusal forces combined with inflammation can cause increased bone loss and attachment loss. The Effectiveness of Clinical Parameters and IL-1 Genotype in Accurately Predicting Prognoses and Tooth Survival . 2005 May 1;69(5):498-508. Int J Periodontics Restorative Dent 2:65–70 Google Scholar. Individual tooth prognosis referrers to the prognosis of an individual tooth, based on local and prosthetic/restorative factors that have a direct effect on its prognosis. In teeth with furcation involvement, the grade of furcation involvement, Periobasics A Textbook of Periodontics and Implantology, Text Book of Basic Sciences for MDS Students. <> Table 1 Classification of prognosis after McGuire (1991). The distribution of reaming teeth is also important. However, based on the factors discussed above, many researchers have recommended different categories of prognosis. One should be well versed with the basic principles of fixed prosthodontics to determine prosthetic prognosis. However, there is limited direct evidence in … Further, a periodontal assessment, including probing depths should be conducted to assess the prognosis for the tooth. Center of tooth rotation should also be considered along with crown-root ratio. The rate of disease progression may be rapid or slow. 2004 Feb;34(1):165-203. A thorough analysis of the factors discussed above guides us to determine the individual tooth and overall prognosis of a patient. The periodontal status of the tooth is influenced by local and/or systemic factors that may or may not be able to be controlled. Increasing bone loss is associated with an increase in tooth mobility. The patient-level factors include smoking, poorly controlled diabetes and bleeding on probing. Prognosis. J. Periodontol. 62:51-58, 1991. Gingivitis is the mildest form of periodontal disease and can be found in up to 90% of the population. In dentistry prognosis of a particular tooth or teeth depends on various factors. TYPES OF PROGNOSIS McGuire MK, Nunn ME, 1996, based on studies evaluating tooth mortality, the following classification has been proposed: Good prognosis: Control of etiologic factors adequate periodontal support easy to maintain by the patient and clinician. The tradition-al systems were based on tooth mortality19 and did not look at the possibility of classify-ing a tooth’s prognosis, based on the ability to control the disease process and success- A favorable crown-root ratio is considered as a good prognostic factor.
