Classification of prognosis by tooth type (molars vs. non-molars) from multivariate exponential survival trees. So, it is advisable that only a provisional prognosis should be established for a patient until Phase I therapy is completed and evaluated. It should be remembered that prognosis does not remain the same for a patient. Patients commonly ask about the prognosis of their dentition and it becomes the moral duty of the dentist to explain it to the best of his/her capability. The treatment may vary from primary periodontal treatment for stopping the disease progression to regenerative procedures. The prognosis can also be classified as individual prognosis or overall prognosis. Various factors which determine individual tooth prognosis are, It refers to the prognosis of the teeth based on the sum of various local, systemic, environmental and other factors which may affect the overall periodontal health of the teeth. These common factors suggest that for any given diagnosis, there should be an expected prognosis under ideal conditions. Contents available in the book ……….. A. Rabel, S. G.

It has been generally assumed that there is a paucity of knowledge on periodontal prognosis. Dr. Oh uses this but initial prognosis she uses McGuire Nunn. Previous studies by McGuire [19.] It has been generally assumed that there is a paucity of knowledge on periodontal prognosis. The New Classification is the product of the World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions, held in Chicago in November 2017. 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. Let us now discuss in detail the factors affecting the prognosis of teeth. The root concavities are most commonly present on the maxillary first premolar and the mesiobuccal root of the first molar. 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.

This new classi-fication has numerous subcategories; only the major categories will be discussed here. The tooth level factors include ratio of bone loss: age, periodontal pocket depth, extent of furcation involvement, presence of an infrabony defect, compromising anatomical factors and the extent of tooth mobility. More the number of teeth present in oral cavity better is the prognosis. Start studying Prognosis. Quizlet flashcards, activities and games help you improve your grades. Various mechanisms by which smoking causes increased periodontal destruction have been discussed in the “Smoking as a risk factor for periodontal diseases”. Increasing bone loss is associated with an increase in tooth mobility. Teeth with short, slender and tapering roots have a poorer prognosis than teeth with long and broad roots. It is a well-established fact that smoking is associated with poor prognosis in a periodontally compromised patient. El pronóstico es una predicción del curso de la enfermedad. However, based on the factors discussed above, many researchers have recommended different categories of prognosis. The presence of pseudo-pockets is a good prognostic factor as these represent increase in the size of soft tissue only . Scaling and root planing of the root surfaces are essential for the maintenance of periodontal health. Very Good Good Fair Poor Hopeless. In this carefully reviewed article, Perio-Implant Advisory's Editorial Director Dr. Scott Froum provides a simple summary of the new classification of periodontal disease and peri-implant disease, as well as a discussion of the staging and progression of periodontitis. 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 bone loss has to be seen in relation to root length. The information presented in this website has been collected from various leading journals, books and websites. A review of the literature by Kinane (1997) 22 found considerable evidence to suggest that diabetes and periodontitis have a direct relationship. Development of an accurate prognosis is an integral component of treatment planning in the practice of periodontics. stream Trauma from occlusion and parafunctional habits: Abnormal occlusal forces and parafunctional habits may cause injury to the periodontal apparatus. Various studies have found that it is very difficult to determine the exact prognosis of periodontally compromised teeth after their appropriate periodontal treatment. There is no evidence of a specific pathophysiology that enables the differentiation 1 0 obj Contents available in the book …….. Pockets present on the proximal surfaces have a better prognosis than in other areas such as furcation. In teeth, with short roots, a small amount of bone loss may create a significant difference, whereas a large amount of bone loss around long roots may not result in significant loss of support. 2005 May 1;69(5):498-508. In general, the prognosis is guarded with a complex and extensively complex prosthesis as compared to the simple prosthesis or no prosthesis at all. Categories of prognosis proposed by McGuire (1991) 2 and Kwok and Caton (2007) 32 are given in the following tables. Prognosis versus actual outcome: A. Overlapping clinical situations and exceptions to the rule certainly exist and pose challenges to clinicians during diagnosis, prognosis, and treatm … The development of an accurate prognosis is an integral component of treatment planning in the practice of periodontics. Usually, patients commonly ask questions like, for how many years my teeth will be all right after this treatment? 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. Recently, McGowan et al. Nieminen A, Sirén E, Wolf J, Asikainen S. Prognostic criteria for the efficiency of non‐surgical periodontal therapy in advanced periodontitis. A classification for gingivitis and periodontitis has been proposed based on clinical observations and immunologic parameters (summarized in Table 10). As already stated, the overall prognosis is the sum of multiple factors that have a direct or indirect relationship with periodontal disease progression. 1991 Jan;62(1):51-8. doi: 10.1902/jop.1991.62.1.51. It is a bad prognostic factor, because furcation is difficult to access and treat. A thorough analysis of the factors discussed above guides us to determine the individual tooth and overall prognosis of a patient. 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. IV. Following a complete evaluation of the patient, treatment planning requires the analysis of individual teeth, accurate diagnosis, and prognosis evaluation. The root concavities are most commonly present on the maxillary first premolar and the mesiobuccal root of the first molar. Firm teeth, even with advanced bone loss have a better prognosis than loose teeth. Journal of periodontology. Contents available in the book ……….. The systemic condition of the patient is a very important factor in the determination of the overall prognosis.

When bone loss increases beyond 50%, tooth mobility increases rapidly with each millimeter of further bone loss. II. The presence of developmental structures such as enamel projections and developmental grooves worsen the prognosis of the involved tooth. 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.

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. Scaling and root planing of the root surfaces are essential for the maintenance of periodontal health. It also refers to the determination of whether the prosthesis to be planned shall be therapeutic or detrimental. 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 … Journal of dental education. The bone loss has to be seen in relation to root length. 1 New technology, research, and information has emerged in the past 18 years which led to the new revisions. What categories are considered? J. Periodontol. Previous studies by McGuire [19.] In dentistry prognosis of a particular tooth or teeth depends on various factors. 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. The periodontal status of the tooth can be stabilized with comprehensive periodontal treatment and periodontal maintenance. Periodontal Disease and Diabetes Mellitus: Case Report H Marie Keeling1 ... prognosis of all maxillary teeth, 4-1, 3-1, 4-3 and 4-7 to be hopeless, according to McGuire’s classification system(3), and teeth4-2 and 3-2 had questionable prognosis as well. INTRODUCTION. Previous studies in this series evaluated prognosis as a surrogate variable representing the condition of the tooth at a particular point. Several studies 10-17 reported the prevalence of cervical enamel projections ranging from 8.6 % to 85 %. Technique. Contents available in the book …….. Hence, retaining such a tooth is not a wise decision. Also, the quality of remaining teeth is important. Further, a periodontal assessment, including probing depths should be conducted to assess the prognosis for the tooth. Retrospective study of tooth loss in 92 treated periodontal patients. If the missing teeth are distributed in an arch in such a way that remaining teeth can withstand the occlusal forces when rehabilitated with a prosthesis, it is always a good prognostic factor. Prognosis Versus Actual Outcome. J. Periodontol. These forces may result in mobility, wear facets, and enlargement of the periodontal ligament space. AU - McGuire, Michael K. AU - Nunn, Martha E.

The aim of this study is to investigate the factors affecting the prognosis of endo-periodontal lesions. Establishing the prognosis of periodontally involved tooth or teeth is indeed difficult. 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. Pockets present on the facial and lingual/palatal surfaces may result in loss of bony plate over the convexities of the root surface. For example, the maxillary first premolars show increased tooth mobility because these have conical and tapered roots. The present evidence clearly suggests that emotional stress can modulate the immune system through the neural and endocrine systems in at least three different ways, including the autonomic nervous system pathway, through the release of neuropeptides and through the release of hypothalamic and pituitary hormones 26-28. These percentages were much higher for questionable prognosis: the TLPD prediction failed in between 37% and 74% of cases (Becker et al., 1984; McFall, 1982; McGuire & Nunn, 1996). Describe the McGuire classification of prognosis. While discussing the prognosis with the patient, initially, the patient should be told about the diagnostic prognosis (i.e., what will happen if no treatment is provided), then the therapeutic prognosis (i.e., status of teeth after the treatment is provided) and if indicated, the prosthetic prognosis (i.e., future prediction of prosthetic restoration of teeth after periodontal treatment). In general, two third to one half of the investing bone is the minimal requirement for a tooth to have a favorable prognosis. Clinical features and initial outcome. 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. Rotstein I, Simon JH. It is always better to have. 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. However, with accurate analysis of the periodontal condition, occlusion, systemic factors and patient motivation a predictable prognosis can be determined most of the times. Similarly, in a series of studies, McGuire and Nunn (1991, 1996) 2, 3 concluded that it is difficult to predict the prognosis of teeth with an initial prognosis of less than good. An evidence-based scoring index to determine the periodontal prognosis on molars.Miller PD Jr, McEntire ML, Marlow NM, Gellin RG.J Periodontol 2014;85… An inadequate width of attached gingiva, recession, high frenal attachment, and presence of periodontal pockets below the level of mucogingival junction are all related to poor prognosis. Categories of prognosis proposed by McGuire (1991) 2 and Kwok and Caton (2007) 32 are given in the following tables. Risk Assessment, Prognosis and Clinical Significance in Periodontal Diseases study guide by Ashley_Hinsch includes 67 questions covering vocabulary, terms and more. Determination of prognosis and The Treatment plan for periodontal disease Further, difficult to reach areas such as maxillary and mandibular posterior-most areas are more difficult to maintain as compared to the anterior areas. These are also seen on both the root surfaces of mandibular first molars and incisors 9. 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. However, based on the factors discussed above, many researchers have recommended different categories of prognosis. McGuire MK. In general, two third to one half of the investing bone is the minimal requirement for a tooth to have a favorable prognosis. IV. Kwok V, Caton JG.

Research output: Contribution to journal › Article. This would be in line with the rather low accuracy of tooth loss predictions utilising conventional prognostic indexes. Appropriate surgical procedures are required to correct these problems to improve the overall prognosis of the teeth. As we know that periodontal disease progresses in an episodic manner, the active period is associated with signs and symptoms of disease activity, whereas the inactive period does not demonstrate signs and symptoms of the disease. In general, tilted, rotated or drifted teeth have a worse prognosis as compared to well-aligned teeth. 4 0 obj We critically review the use of multivariate classification and regression trees (CART) for survival in developing evidence-based periodontal prognostic indicators. Future loss of the periodontal supporting tissues is unlikely. In other words, we can say that what will be the status of the teeth under question in the future if no treatment is provided for the present periodontal condition. Contents available in the book ……….. It must be remembered that a severely involved tooth jeopardizes the adjacent teeth. When bone loss increases beyond 50%, tooth mobility increases rapidly with each millimeter of further bone loss. While routine periodontal therapy can be afforded by many patients, extensive periodontal surgical procedures or dental implants may raise financial concern for many patients. Good is when there are two or more factors - less than 50% bones loss - no furcation involvement - less then 2 mm mobility. The grossly carious teeth should be restored to improve the overall progno-sis of teeth. Periodontal prognosis ... Miller PD (1985) A classification of marginal tissue recession. Table 5. Prognosis is an integral part of the periodontal practice because it directly influences treatment planning. $.' 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. In general, long root trunk, a wide furcation, and a crown fornix near cementum-enamel junction are poor prognostic factors for furcation involvement 8.
