It also refers to the determination of whether the prosthesis to be planned shall be therapeutic or detrimental. Contents available in the book …….. NunnPrognosis versus actual outcome. Periodontal diseases are disease processes involving the periodontium, a term used to describe the supportive apparatus surrounding a tooth, which includes the gums (gingiva), alveolar bone, cementum, and periodontal ligament. The grossly carious teeth should be restored to improve the overall progno-sis of teeth. More the center of rotation, Tooth root morphology plays an important role in periodontal maintenance. This would be in line with the rather low accuracy of tooth loss predictions utilising conventional prognostic indexes. See this chart from the AAP on staging and grading of periodontal disease. IV. What categories are considered? 25% attachment loss and/or class I furcation involvement. Grade III and Grade IV furcation involvements do not have a good prognosis. It is the prognosis of the teeth if no treatment is provided. McGuire MK (1991) Prognosis versus actual outcome: a long-term survey of 100 treated periodontal patients under maintenance care. 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. These are also seen on both the root surfaces of mandibular first molars and incisors 9. >75% attachment loss, class III mobility. It is hard for clinicians to predict their prognosis. 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. J Periodontol 2007;78:2063–2071. A tooth with an endodontic-periodontal lesion can be categorized as having a hopeless, poor, or favourable prognosis. Michael K. McGuire, Martha E. Nunn. It is a well-established fact that smoking is associated with poor prognosis in a periodontally compromised patient. 5. Contents available in the book ………..

Various factors which determine overall tooth prognosis are, The remaining bone support is directly proportional to the prognosis of the tooth. Long-standing endodontic involvement may result in the formation of a periapical lesion. Prior work has evaluated the validity of using various clinical measured parameters for assigning periodontal prognosis as well as for predicting tooth survival and change in … The bone loss has to be seen in relation to root length. Journal of dental education. What does questionable mean in the Becker, Berg, and Becker include? A summary paper of the workshop by Dr. Gary Armitage is available on the AAP Web site at Keeping in mind the financial status of the patient, it is the duty of the dentist to suggest best treatment options available for that particular patient. When bone loss increases beyond 50%, tooth mobility increases rapidly with each millimeter of further bone loss. All of these classification schemes combine to provide the periodontal diagnosis of the aforementioned … Initial furcation involvement can be treated with non-surgical and surgical periodontal therapy and responds well to the treatment. The prognosis can be classified in two ways. ���� JFIF ` ` �� C Multi-rooted teeth with flared roots have a better prognosis than teeth with close together or fused roots. The correction of occlusal abnormalities should be considered as an important component of the comprehensive treatment plan.

In an effort to improve one’s prognostic skill, one should make a conscious effort to keep on re-evaluating the patient over a long period of time so that factors that influence the success or failure of therapy can be identified and analyzed. 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. 62:51-58, 1991. The broad occlusal surface is a bad prognostic factor as it may cause increased tooth mobility. Mucogingival defects including gingival recession occur in 88% of adults aged ≥65 years and 50% of people aged 18-64 years. A thorough analysis of the factors discussed above guides us to determine the individual tooth and overall prognosis of a patient. The prognosis can also be classified as individual prognosis or overall prognosis. The epidemiological studies have provided irrefutable evidence that smoking adversely affects the prognosis in a periodontally compromised patient and the mechanisms by which it does so 23. 13.

The Miller–McEntire Score for Molars Provides an Evidence-based Approach to Assigning Periodontal Prognosis for ... prognostic indicators using classification and regression trees for survival. 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. AU - McGuire, Michael K. AU - Nunn, Martha E. PY - 1996/7. The remaining bone support is directly proportional to the prognosis of the tooth. ... A system for assigning periodontal prognosis. ………. The effectiveness of clinical parameters in developing an accurate prognosis. Table 1 Classification of prognosis after McGuire (1991). Researchers found that periodontal regeneration is a clinically suitable and less costly alternative to tooth extraction and prosthetic rehabilitation for teeth compromised by extremely severe attachment loss up to or beyond the apex. The classification includes systemic modifying factors thus recognizing the role of factors such as diabetes and smoking on the onset and progression of periodontal disease. This is because occlusal forces are distributed adequately among all the teeth. 50-75% attachment loss and/or class II inaccessible furcation involvement, class III furcation involvement, class II mobility. 134-142.

In general, two third to one half of the investing bone is the minimal requirement for a tooth to have a favorable prognosis. This new classi-fication has numerous subcategories; only the major categories will be discussed here. The systemic condition of the patient is a very important factor in the determination of the overall prognosis. These forces may result in mobility, wear facets, and enlargement of the periodontal ligament space. A favorable crown-root ratio is considered as a good prognostic factor. The morphological deformities of the root surface such as concavities, grooves or bizarre morphology jeopardize these procedures. In general, two third to one half of the investing bone is the minimal requirement for a tooth to have a favorable prognosis. endobj
Various studies have found that it is very difficult to determine the exact prognosis of periodontally compromised teeth after their appropriate periodontal treatment.

Recently, McGowan et al. }���5\�5T����� Classification of Periodontal Disease and Conditions2 (Table 2) and has been accepted by the AAP. Abstract. Very Good Good Fair Poor Hopeless. Initial stage should be determined using clinical attachment loss (CAL). Table 5. These common factors suggest that for any given diagnosis, there should be an expected prognosis under ideal conditions. Describe the McGuire classification of prognosis. Categories of prognosis proposed by, Whether to retain or extract the involved tooth, After critically analyzing the tooth-related and patient-related factors, the decision about retaining or extracting a tooth should be made. When comparing two patients, one 30 years old and another 65 years old having a similar periodontal bone loss, the younger patient has a poor prognosis as compared to the older patient. Problem List- Systemic Conditions (diabetes), risk factors (smoking), clinical findings, secondary finding (overhangs, etc) SJ 31/32 Posterior proximal 5. A simplification of the McGuire (1991) classification of periodontal prognosis was proposed by Checchi et al (2002). Diagnosis, prognosis and decision‐making in the treatment of combined periodontal‐endodontic lesions. 2005 May 1;69(5):498-508. In patients with slow disease progression, the prognosis of teeth is always better than those with rapid disease progression. One classification of prognosis classifies it as diagnostic, therapeutic or prosthetic prognosis and the other classification classifies it as the individual and overall prognosis. Prognosis is the prediction of the probable course, duration, and outcome of a disease, based on the general knowledge of the pathogenesis of the disease and the presence of risk factors for the disease 4.

The New Classification from the 2017 World Workshop on Periodontal and Peri-implant Disease and Conditions (“the World Workshop”) reviewed the scientific evidence and reached four main conclusions: 1. The development of an accurate prognosis is an integral component of treatment planning in the practice of periodontics. In dentistry, numerous types of classification schemes have been developed to describe the teeth and gum tissue in a way that categorizes various defects. In other words, it can be said that it is very difficult to establish an accurate prognosis of periodontally compromised tooth/teeth. The information presented in this website has been collected from various leading journals, books and websites. McGuire Classification of Tooth Prognosis (Levi 2016): Good: Teeth with adequate periodontal support where the etiologic factors can be controlled, including systemic factors Fair: No more than 25% attachment loss with Grade 1 furcation invasion which can be maintained. 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. More the number of endodontically involved teeth, worse is the prognosis. It is the prognosis of the teeth after an appropriate periodontal treatment is provided.
