II. N2 - 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in clinical practice, yet there is little evidence to support the current decision-making process which is based on an outdated model of disease etiology and progression. In other words, it can be said that it is very difficult to establish an accurate prognosis of periodontally compromised tooth/teeth. 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.

McGuire MK, Nunn ME J Periodontol 1996 Jul;67(7):658-65. doi: 10.1902/jop.1996.67.7.658. The method of generalized estimating equations (GEE) for correlated data was utilized to determine the relationship of each clinical factor to the assignment of initial prognosis, improvement in prognosis at 5 years, and worsening in prognosis at 5 years.

IV: The effectiveness of clinical parameters and IL-1 genotype in accurately predicting prognoses and tooth survival. 1982, Becker et al. 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. Prognosis versus actual outcome. III The effectiveness of clinical parameters in accurately predicting tooth survival. The development of an accurate prognosis is an integral component of treatment planning in the practice of periodontics. perio status can be stabilized w/ … When teeth with "good" prognoses were excluded, the predictive accuracy dropped approximately 50%. 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. Smoking decreased the likelihood of improvement by 60% and doubled the likelihood of worsening in prognosis at 5 years. The effectiveness of clinical parameters and IL-1 genotype in accurately predicting prognoses and tooth survival. Prognosis versus actual outcome. In spite of anticipated poor prognosis, the tooth lesion healed. Martha E. Nunn, William G. Carney, Stuart J. McNally, The Miller–McEntire Score for Molars Provides an Evidence-based Approach to Assigning Periodontal Prognosis for Molar Teeth, Journal of Evidence Based Dental Practice, 10.1016/j.jebdp.2015.03.009, 15, 2, (73-76), (2015).

The data also demonstrated that the traditional approach for assigning prognoses is ineffective for teeth with an initial prognosis of less than good. 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).

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. In this study, survival analysis was used to evaluate the relationship of these common clinical parameters to an actual end point, tooth loss. A systematic review on the use of residual probing depth, bleeding on probing and furcation status following initial periodontal therapy to predict further attachment and tooth loss. eCollection 2020 Jun. COVID-19 is an emerging, rapidly evolving situation. J Periodontol 1996;67:658-65. The effectiveness of clinical parameters in accurately predicting tooth survival. These results seem to indicate that the effect of these clinical parameters on tooth survival is only partially reflected in the assigned prognosis initially, suggesting that perhaps some of the clinical parameters should be weighed more heavily than others when assigning prognosis. 9. 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). III. The Effectiveness of Clinical Parameters and IL-1 Genotype in Accurately Predicting Prognoses and Tooth Survival. HHS 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. This site needs JavaScript to work properly. 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. The data also demonstrated that the traditional approach for assigning prognoses is ineffective for teeth with an initial prognosis of less than good. Smoking decreased the likelihood of improvement by 60% and doubled the likelihood of worsening in prognosis at 5 years. The method of generalized estimating equations (GEE) for correlated data was utilized to determine the relationship of each clinical factor to the assignment of initial prognosis, improvement in prognosis at 5 years, and worsening in prognosis at 5 years.
