We report the results of a survey of family members on their attitudes to the disclosure of the diagnosis. The coefficients from this model were able to predict accurately the 5-year and 8-year prognoses 81% of the time. McGuire Nunn Classification - based on tooth loss. The Effectiveness of Clinical Parameters and IL-1 Genotype in Accurately Predicting Prognoses and Tooth Survival. b/w 25-50% attachment loss, class II furcation. In addition, good hygiene was found to increase the probability of improvement in prognosis while initial mobility was found to decrease the likelihood of improvement in prognosis. eCollection 2020 Jun. 1996. Neither of these factors was found to be significant in worsening of prognosis. Category Definition very good <25% attachment loss good 25% attachment loss and/or class I furcation involvement fair 25–50% attachment loss and/or easily accessible class II furcation involvement poor A positive IL-1 genotype increased the risk of tooth loss by 2.7 times, and heavy smoking by 2.9 times. Increased probing depth, more severe furcation involvement, greater mobility, unsatisfactory crown-to-root ratio, malpositioned teeth, and teeth used as fixed abutments resulted in worse initial prognoses. The effectiveness of clinical parameters in developing an accurate prognosis. Histological comparison of different compressive forces on particulate grafts during alveolar ridge preservation: a prospective proof-of-concept study. McGuire MA, Robotin MC, Bourke JP, Yip ASB, Johnson DC, Dewsnap BI  |  IV. 1996;67;666-674. 1996; 67:666–674. J Periodontal Implant Sci. The results of this study indicate that some clinical factors used in the assignment of prognoses are clearly associated with changes in clinical condition over time. One hypothesis for the increased periodontal changes noted in smokers is that the periodontal pockets of smokers tend to be more anaerobic compared to nonsmokers.8 An anaerobic environment could conceivably promote the growth of Gram-negative periodontal pathogens in the subgingival plaque. A multiple linear regression model was constructed for predicting initial prognosis based on initial clinical data. The effectiveness of clinical parameters in developing an accurate prognosis. J Periodontol. up to 25% attachment loss and/or class I furcation. Prognosis versus actual outcome. Robust log rank tests indicated that initial probing depth, initial furcation involvement, initial mobility, initial crown-to-root ratio, and initial root form were all associated with tooth loss. 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. Since most periodontally involved teeth are compromised, further work should include the development of a more effective method for assigning prognoses that is based on clear, objective clinical criteria. The system categorized teeth as “good,” “fair,” “poor,” “questionable,” and “hopeless.” Their first 2 McGuire MK, Nunn ME. Furthermore, initial prognosis did not adequately explain the condition of the tooth or accurately predict the tooth's survival. Patient keeping tooth or not. Search across a wide variety of disciplines and sources: articles, theses, books, abstracts and court opinions. Increased probing depth, more severe furcation involvement, greater mobility, unsatisfactory crown-to-root ratio, malpositioned teeth, and teeth used as fixed abutments resulted in worse initial prognoses. Prognosis versus actual outcome. 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 results of this study indicate that some clinical factors used in the assignment of prognoses are clearly associated with changes in clinical condition over time. Pronóstico Periodontal de McGuire-Nunn: De la Teoría a la Práctica Previous studies in this series evaluated prognosis as a surrogate variable representing the condition of the tooth at a particular point. Although many periodontal prognosis systems have been developed, most of the prognoses are based on tooth mortality (i.e., extractions).5–8 Assigning an accurate prognosis for each tooth be…  |  This study evaluated 100 treated periodontal patients (2,484 teeth) under maintenance care for 5 years, with 38 of these patients followed for 8 years, to determine the relationship of assigned prognoses to the clinical criteria commonly used in the development of prognosis. The assignment of prognosis is one of the most important functions undertaken in clinical practice, yet there is little evidence to support the current decision-making process which is based on an outdated model of disease etiology and progression. From these data there does appear to be a relationship between the assigned prognosis and tooth loss. 1982, Becker et al. J Periodontol. NLM Multiple logistic regression models indicated that improvement in prognoses and worsening in prognoses were both strongly associated with initial probing depth, initial furcation involvement, initial tooth malposition, and smoking when adjusted for initial prognosis. AU - McGuire, Michael K. AU - Nunn, Martha E. PY - 1996/7. The results of this study indicate that some clinical factors used in the assignment of prognoses are clearly associated with changes in clinical condition over time. In addition, good hygiene was found to increase the probability of improvement in prognosis while initial mobility was found to decrease the likelihood of improvement in prognosis. Y1 - 1999/1/1 3 ‡ 9.97 year s 2,509 2 ... McGuire MK, Nunn ME. - published after Dr. Oh graduated. 2020 Mar;15(1):50-58. doi: 10.1016/j.jds.2019.08.008.

III The effectiveness of clinical parameters in accurately predicting tooth survival. II. The Pervasive Refusal Syndrome is a recently described syndrome of child psychiatric disorder. Teeth with worse prognosis have a worse survival rate, but the commonly taught clinical parameters used in the traditional method of assignment of prognosis do not adequately explain that relationship. Clipboard, Search History, and several other advanced features are temporarily unavailable. III. T1 - Prognosis Versus Actual Outcome. A multiple linear regression model was constructed for predicting initial prognosis based on initial clinical data. In other words, it can be said that it is very difficult to establish an accurate prognosis of periodontally compromised tooth/teeth. perio status can be stabilized w/ … In spite of anticipated poor prognosis, the tooth lesion healed. The effectiveness of clinical parameters in developing an accurate prognosis". According to The Merriam-Webster Dictionary, “Prognosis” is defined as “the prospect of recovery as anticipated from the usual course of disease or peculiarities of the case.” In medicine, however, the term is commonly defined by the mortality rate. Since most periodontally involved teeth are compromised, further work should include the development of a more effective method for assigning prognoses that is based on clear, objective clinical criteria.

Thus, it has generally been assumed that the mean probability of accurately predicting tooth loss, excluding good prognosis, is close to being a chance occurrence or comparable to a coin toss (McGuire & Nunn 1996). J Periodontol. Periodontal regeneration versus extraction and dental implant or prosthetic replacement of teeth severely compromised by attachment loss to the apex: A randomized controlled clinical trial reporting 10-year outcomes, survival analysis and mean cumulative cost of recurrence. McGuire MK, Nunn ME J Periodontol 1996 Jul;67(7):658-65. doi: 10.1902/jop.1996.67.7.658. The effectiveness of clinical parameters in accurately predicting tooth survival. Smoking decreased the likelihood of improvement by 60% and doubled the likelihood of worsening in prognosis at 5 years. The development of an accurate prognosis is an integral component of treatment planning in the practice of periodontics. ~A hopeless prognosis is more accurate than a questionable prognosis in predicting tooth loss in these patients. J Periodontol 1996;67:666-74. Prognosis versus actual outcome.
