After critically analyzing the tooth-related and patient-related factors, the decision about retaining or extracting a tooth should be made. Simple periodontal treatments can halt the progression of periodontal diseases and in a well-motivated patient, the prognosis becomes favorable. The periodontal status of the tooth is influenced by local and/or systemic factors that cannot be controlled. 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. Increasing bone loss is associated with an increase in tooth mobility. In dentistry prognosis of a particular tooth or teeth depends on various factors. Prognosis … ",#(7),01444'9=82. Methods . 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. Contents available in the book ……….. In other words, it can be said that it is very difficult to establish an accurate prognosis of periodontally compromised tooth/teeth. When bone loss increases beyond 50%, tooth mobility increases rapidly with each millimeter of further bone loss. 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. Periodontal literature Most of the attempts to attach a classification for the prognosis of individual teeth come from the periodontal literature. Optimal management of periodontally diseased molar requires precise and reliable means to assess their prognosis. Technique. A simplification of the McGuire (1991) classification of periodontal prognosis was proposed by Checchi et al (2002). Contents available in the book …….. … Contents available in the book …….. … Contents available in the book …….. 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. J Periodontal 62:51–58 Google Scholar 21. The broad occlusal surface is a bad prognostic factor as it may cause increased tooth mobility. AU - McGuire, Michael K. AU - Nunn, Martha E. PY - 1996/7. Center of tooth rotation should also be considered along with crown-root ratio. (2017) 33, proposed an evidence-based periodontal prognosis model. Describe the McGuire classification of prognosis. 25% attachment loss and/or class I furcation involvement. Further, if many teeth are missing and the remaining teeth are also supporting removable or fixed prosthesis, the prognosis is even poor. 12. In teeth with furcation involvement, the grade of furcation involvement ………. In general, the prognosis is guarded with a complex and extensively complex prosthesis as compared to the simple prosthesis or no prosthesis at all. Diagnostic and prognostic tests for oral diseases: practical applications. It is always better to have.
$.' Initial furcation involvement can be treated with non-surgical and surgical periodontal therapy and responds well to the treatment. Dr. Oh uses this but initial prognosis she uses McGuire Nunn. J … The association between periodontal disease and diabetes mellitus (DM) is well documented. While routine periodontal therapy can be afforded by many patients, extensive periodontal surgical procedures or dental implants may raise financial concern for many patients. However, due to marked differences in their post-operative course, these patients lost zero to 23 teeth per patient during this period of evaluation. The individual tooth prognosis is an integral component of these factors. The knowledge and ability of the dentist play a significant role in the overall prognosis of the patient. 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. However, with accurate analysis of the periodontal condition, occlusion, systemic factors and patient motivation a predictable prognosis can be determined most of the times. 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. In dentistry, numerous types of classification schemes have been developed to describe the teeth and gum tissue in a way that categorizes various defects. It has been demonstrated that the odds ratio for the development of periodontal disease in association with smoking is 3.97 for current smokers and 1.68 for former smokers 24 and 3.25 for light smokers and 7.28 for heavy smokers 25. However, as bone loss exceeds, In general, increased tooth mobility is a poor prognostic factor. In general, teeth with shallow periodontal pockets have a better prognosis than teeth with deep pockets (8 mm or more). Also, the quality of remaining teeth is important. 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 … Also, the quality of remaining teeth is important. %PDF-1.5

It may be usually expected that the younger patient may have a greater bone reparative capacity as compared to the older patient, but a rapid bone loss in a short period of time in a younger patient does not go in favor of good bone reparative capacity. The periodontal disease progression associated with smoking is dose-dependent 24. 5. � �����I���w�z-�V�%��8�I�Ò-���r1@�m+�fɲ) کn�["��0|w�S�VȮ��f~���~���^�$�v5�~ۯ��/�e���i��-2d\��T4�q����Wt�̵��ܶ#bܒ������,6F��ry~. 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. stream
13. The bone loss has to be seen in relation to root length. 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 authors elected to define prognosis based on residual bone levels and/or furcation involvement. 5 0 obj
Journal of Clinical Periodontology. All of these classification schemes combine to provide the periodontal diagnosis of the aforementioned … Inflammatory response consistent with the presence of local factors is a good prognostic factor. The association between periodontal disease and diabetes mellitus (DM) is well documented. A favorable crown-root ratio is considered as a good prognostic factor. 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). Two major factors contributing to the patient’s periodontal status could be due to her poor oral … what's the McGuire and Nunn classification? 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). Start studying (2) Perio--Periodontal 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. It must be remembered that a severely involved tooth jeopardizes the adjacent teeth. Faggion Jr CM, Petersilka G, Lange DE, Gerss J, Flemmig TF. 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.

J. Periodontol. The presence of mucogingival problems is associated with a bad prognosis. 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. In general, two third to one half of the investing bone is the minimal requirement for a tooth to have a favorable prognosis. Prognosis versus actual outcome: A. Scaling and root planing of the root surfaces are essential for the maintenance of periodontal health. Various mechanisms by which smoking causes increased periodontal destruction have been discussed in the “Smoking as a risk factor for periodontal diseases”. or what will be the life of my tooth, which is causing me trouble? 3 0 obj
Quizlet flashcards, activities and games help you improve your grades. However, the complexity of the prosthesis fabricated should be considered while the determination of the prognosis. This is because occlusal forces are distributed adequately among all the teeth. A classification for gingivitis and periodontitis has been proposed based on clinical observations and immunologic parameters (summarized in Table 10). 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 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.

Journal of dental education. The broad occlusal surface is a bad prognostic factor as it may cause increased tooth mobility. 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. [1,2] DM can be controlled by lifestyle intervention, education, self-monitoring, and self-management by … 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. 62:51-58, 1991. Various factors which determine individual tooth prognosis are 5. Patient keeping tooth or not. Thus, this low sensitivity or capability of anticipating the TLPD event represents a major limitation of peri-odontal prognosis. Abnormal occlusal forces and parafunctional habits may cause injury to the periodontal apparatus. The patient-level factors include smoking, poorly controlled diabetes and bleeding on probing. 1991 Jan;62(1):51-8. doi: 10.1902/jop.1991.62.1.51. 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- Pockets present on the proximal surfaces have a better prognosis than in other areas such as furcation. The presence of pseudo-pockets is a good prognostic factor as these represent increase in the size of soft tissue only . Endodontic examination serves to improve treatment planning, performance, and prognosis. The periodontal status of the tooth is influenced by local and/or systemic factors that may or may not be able to be controlled. 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.

Various studies have found that it is very difficult to determine the exact prognosis of periodontally compromised teeth after their appropriate periodontal treatment. This would be in line with the rather low accuracy of tooth loss predictions utilising conventional prognostic indexes. Hence, it is difficult to establish a prognosis for the patient. Classification of Periodontal Disease and Conditions2 (Table 2) and has been accepted by the AAP. This would be in line with the rather low accuracy of tooth loss predictions utilising conventional prognostic indexes. The prognosis can be classified in two ways. 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. It is hard for clinicians to predict their prognosis. <>
