This is because oral hygiene is more difficult to maintain in areas with malaligned teeth. Methods . The periodontal disease progression associated with smoking is dose-dependent 24. 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. Long-standing endodontic involvement may result in the formation of a periapical lesion. Overlapping clinical situations and exceptions to the rule certainly exist and pose challenges to clinicians during diagnosis, prognosis, and treatm … 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. One study examined 5,230 extracted molars and concluded that 25.2% of mandibular molars and 15.8% of maxillary molars demonstrated the presence of cervical enamel projection 11. If the patient’s response to phase I therapy is good and there is a considerable reduction in inflammation and pocket depth the prognosis may be better than as assumed before the treatment. However, with accurate analysis of the periodontal condition, occlusion, systemic factors and patient motivation a predictable prognosis can be determined most of the times. Classification of Periodontal Disease and Conditions2 (Table 2) and has been accepted by the AAP. Kwok V, Caton JG. Let us now discuss in detail the factors affecting the prognosis of teeth. 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). 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. Appropriate surgical procedures are required to correct these problems to improve the overall prognosis of the teeth. Prognosis Versus Actual Outcome. Contents available in the book ……….. However, there is limited direct evidence in … Patients who show a severe response to the minimal amount of plaque accumulation have a poor prognosis. When bone loss increases beyond 50%, tooth mobility increases rapidly with each millimeter of further bone loss. The presence of developmental structures such as enamel projections and developmental grooves worsen the prognosis of the involved tooth. 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. This would be in line with the rather low accuracy of tooth loss predictions utilising conventional prognostic indexes. 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. Contents available in the book …….. Contents available in the book ……….. What categories are considered? endobj Periodontal prognosis ... Miller PD (1985) A classification of marginal tissue recession. The periodontal prognosis of treated non-vital teeth does not differ from that of vital teeth. So, it is advisable that only a provisional prognosis should be established for a patient until Phase I therapy is completed and evaluated. 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 … It is the prognosis of the teeth if no treatment is provided. Prognosis. The periodontal status of the tooth can be stabilized with comprehensive periodontal treatment and periodontal maintenance. A classification for gingivitis and periodontitis has been proposed based on clinical observations and immunologic parameters (summarized in Table 10). 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. 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. 1 New technology, research, and information has emerged in the past 18 years which led to the new revisions.

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. 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. Various factors which determine individual tooth prognosis are 5. M.K. Staging intends to classify the severity and extent of a patient’s disease based on the measurable amount of destroyed and/or damaged tissue as a result of periodontitis and to assess the specific factors that may attribute to the complexity of long-term case management. excluding good prognosis, is close to being a chance occurrence or comparable to a coin toss (McGuire & Nunn 1996). 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. Root canal treatment, post and core treatment with crown placement should be included in the treatment plan for these teeth to improve the therapeutic prognosis. Contents available in the book ……….. The broad occlusal surface is a bad prognostic factor as it may cause increased tooth mobility. It must be remembered that a severely involved tooth jeopardizes the adjacent teeth. 1991 Jan;62(1):51-8. doi: 10.1902/jop.1991.62.1.51. The book is usually delivered within one week anywhere in India and within three weeks anywhere throughout the world. Teeth with short, slender and tapering roots have a poorer prognosis than teeth with long and broad roots. (2017) 33, proposed an evidence-based periodontal prognosis model. Development of an accurate prognosis is an integral component of treatment planning in the practice of periodontics. In patients who respond well to the treatment the prognosis improves, whereas in patients where results of treatment are not as expected, the prognosis may worsen. stream Contents available in the book …….. J. Periodontol. 13. 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. Grade I and Grade II furcation involvement respond well to regenerative therapy. References are available in the hard-copy of the website. Although it is very difficult to predict the exact prognosis of the tooth, but if careful examination of the dentition and patient as a whole is done, one can establish a quite accurate prognosis. ………. 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. In general, long root trunk, a wide furcation, and a crown fornix near cementum-enamel junction are poor prognostic factors for furcation involvement 8. Following a complete evaluation of the patient, treatment planning requires the analysis of individual teeth, accurate diagnosis, and prognosis evaluation. The distribution of reaming teeth is also important. However, the complexity of the prosthesis fabricated should be considered while the determination of the prognosis. 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… 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. Previous studies by McGuire [19.] Faggion Jr CM, Petersilka G, Lange DE, Gerss J, Flemmig TF. Presence/absence of occlusal interferences. It is hard for clinicians to predict their prognosis. The loss of periodontal support in relation to patient’s age is an important factor which has to be considered while determining prognosis. Previous studies by McGuire [19.] endobj The correction of occlusal abnormalities should be considered as an important component of the comprehensive treatment plan. Optimal management of periodontally diseased molar requires precise and reliable means to assess their prognosis. J Periodontal 62:51–58 Google Scholar 21. Problem List- Systemic Conditions (diabetes), risk factors (smoking), clinical findings, secondary finding (overhangs, etc) SJ 31/32 Posterior proximal 5. It is always better to have.

Contents available in the book ……….. However, due to marked differences in their post-operative course, these patients lost zero to 23 teeth per patient during this period of evaluation. Firm teeth, even with advanced bone loss have a better prognosis than loose teeth. 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. Recently, McGowan et al. Contents available in the book ……….. The treatment may vary from primary periodontal treatment for stopping the disease progression to regenerative procedures. Both diseases are thought to share a common pathogenesis that involves an enhanced inflamma-tory response that can be observed at the local and systemic level, Inflammatory response consistent with the presence of local factors is a good prognostic factor.

The World Workshop was organised jointly by the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP) to create a consensus knowledge base for a new classification to be promoted … Systemic conditions, like uncontrolled diabetes mellitus, are associated with poor periodontal prognosis. If the periapical lesion is large, apical surgery should be performed. In general, the prognosis is guarded with a complex and extensively complex prosthesis as compared to the simple prosthesis or no prosthesis at all. ���� JFIF ` ` �� C 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). Center of tooth rotation should also be considered along with crown-root ratio. x��W]O�J}�����vE����ЖVTB]��P݇ !D@B�ӏό�d�c�����?fv�93��>��S�������OB�/>|�(�����q8�>X�*��k�,��Q/���r��~88O'���gÁ�QL��-�p����Ji���+e�r2\�Ya-�}bT�e�èD\Z���m,�Cе�e�m���G��� � Ƒ� The alteration in the immune response results in inadequate defense against infection, which favors periodontal disease progression. All of these classification schemes combine to provide the periodontal diagnosis of the aforementioned … After critically analyzing the tooth-related and patient-related factors, the decision about retaining or extracting a tooth should be made. 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. Thus, this low sensitivity or capability of anticipating the TLPD event represents a major limitation of peri-odontal prognosis. The presence of these projections predisposes the tooth to the formation of periodontal pocket, which many times, is difficult to treat. 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 patients were well motivated regarding professional oral health care and personal oral health care, including maintenance of oral hygiene and periodontal health. These are also seen on both the root surfaces of mandibular first molars and incisors, The presence of developmental structures such as enamel projections and developmental grooves worsen the prognosis of the involved tooth. Contents available in the book ……….. Mucogingival defects including gingival recession occur in 88% of adults aged ≥65 years and 50% of people aged 18-64 years. When present, these factors downgrade the prognosis by one level as previous research has established that these factors are significantly associated with an increased risk of tooth 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. Currently, no uniform system for assignment of periodontal prognosis exists. A thorough analysis of the factors discussed above guides us to determine the individual tooth and overall prognosis of a patient. 3 0 obj In teeth with furcation involvement, the grade of furcation involvement ………. The new periodontal classification system emerged from the 2017 World workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. However, based on the factors discussed above, many researchers have recommended different categories of prognosis. Increasing bone loss is associated with an increase in tooth mobility. 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. Patient keeping tooth or not. Contents available in the book ……….. Table 5. The presence of pseudo-pockets is a good prognostic factor as these represent increase in the size of soft tissue only . 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. McGuire MK : Prognosis versus actual outcome: A long-term survey of 100 treated periodontal patients under maintenance care. Periodontal literature Most of the attempts to attach a classification for the prognosis of individual teeth come from the periodontal literature. The association between periodontal disease and diabetes mellitus (DM) is well documented. It is estimated that 47% of people older than age 30 have some form of periodontal […] It also refers to the determination of whether the prosthesis to be planned shall be therapeutic or detrimental. & Linden, 2004; McGuire & Nunn, 1996). $.' Development of an accurate prognosis is an integral component of treatment planning in the practice of periodontics. The association between periodontal disease and diabetes mellitus (DM) is well documented. The grossly carious teeth should be restored to improve the overall progno-sis of teeth. The replacement of missing teeth with a prosthesis is a commonly carried out procedure. Retrospective study of tooth loss in 92 treated periodontal patients. This would be in line with the rather low accuracy of tooth loss predictions utilising conventional prognostic indexes. Establishing the prognosis of periodontally involved tooth or teeth is indeed difficult. The proposed system uses six tooth level and three patient-level factors to give each tooth a prognosis of secure, doubtful, poor or irrational to treat. endobj Usually, patients commonly ask questions like, for how many years my teeth will be all right after this treatment? Once all the treatment is completed, the general dentist can carry on with the maintenance schedule. Periodontol 2000, 58 (1) (2012), pp. or what will be the life of my tooth, which is causing me trouble? Further, difficult to reach areas such as maxillary and mandibular posterior-most areas are more difficult to maintain as compared to the anterior areas. The Effectiveness of Clinical Parameters and IL-1 Genotype in Accurately Predicting Prognoses and Tooth Survival . A detailed discussion of stress and periodontitis is available in “Stress as a risk factor for periodontal diseases”. Diagnostic and prognostic tests for oral diseases: practical applications. 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. 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.
