The influence of various factors that may affect the outcome of root canal therapy was evaluated in 356 patients 8 to 10 yr after the treatment. Tooth loss is frequently associated with bone resorption. Clinicians linked to a training center shared a common treatment philosophy as to when periodontal surgery should be performed. Types of Perio D's 5. ascertain an accurate diagnosis. ... • Continuous alveolar bone growth • Aesthetic concerns particularly in single tooth restoration • Gingival recession over years • Possible susceptibility to periodontal and peri-implant diseases. Mechanical complications were screw loosening/fracture, implant fractures, framework, resin base and veneering material fractures, opposing prosthesis fractures, and overdenture mechanical retention problems. Evaluation was made as to patterns of tooth loss, loss of questionable teeth, loss of teeth with furcations, surgical vs. nonsurgical therapy, and presence of fixed or removable prostheses. Good long-term success rates and greater flexibility in clinical management indicate that RCT or retreatment should be performed first in most instances unless the tooth is judged to be unrestorable. Studies consistently show more periodontal disease and generally greater severity of disease in older as opposed to younger people.1,2,6 Generally, an older patient probably has a better prognosis for a given level of attachment loss than a younger patient does. dentistry. Your email address will not be published. Results showed a favorable long term functional survival rate of 341 teeth (88%) 5 to 24 years after treatment, despite the fact that many teeth had at least one root with 50% or less of bone support before treatment. Your dentist may loosen the tooth in the gum using a tooth removal instrument called an elevator. To aid dentists in making treatment decisions in such cases, the authors present a flowchart that integrates possible considerations. Patients who suffer tooth loss resulting from traumatic injuries of the dentoalveolar complex can be divided into growing and nongrowing patients. Of the 46 teeth (12%) that were ultimately extracted, 25 were present for a significant length of time (6 to 18 years) before extraction. Journal of the California Dental Association, Wurzelkanalbehandlung versus Implantation. Knowledge of IL-1 genotype status would be important in developing a treatment plan and predicting tooth survival for a new patient who smokes and presents with periodontal disease, especially if restorative care is needed. The authors aimed to critically review the literature regarding the relationship between retention of teeth and oral health-related quality of life (OHRQoL) and the extent to which tooth retention can ensure OHRQoL among adults. Most failures were in the mandibular arch and derived from reasons other than inflammatory periodontal disease. 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. A multiple Cox regression model and Kaplan-Meier survival plots were fit to the subset of patients to evaluate tooth loss. Physical and emotional stress as well as substance abuse may alter the patient’s ability to respond to the periodontal treatment performed.6 A recent meta analysis of the literature suggests that psychological stress can lead to increased periodontal disease.2,20, • Patient compliance.

Table 3 Multivariate analysis of the prognostic factors affecting survival. International Endodontic Journal, 44, 610–625, 2011. A positive IL‐1 genotype increased the risk of tooth loss by 2.7 times, and heavy smoking by 2.9 times. Despite the risk of complications, tooth in the fracture line should be preserved for its merits. The corresponding value for SC was 97.5%. Twenty-nine papers-including cross-sectional, longitudinal, clinical trial, and case-control studies-were included and categorized according to 4 subthemes to achieve the stated aim: 1) number of teeth or missing teeth and OHRQoL, 2) occluding pairs or functional units and OHRQoL, 3) position of remaining or missing teeth and OHRQoL, and 4) shortened dental arches (SDAs) and OHRQoL. Previous studies in this series evaluated prognosis as a surrogate variable representing the condition of the tooth at a particular point. The Effectiveness of Clinical Parameters in Developing an Accurate Prognosis, Meta-analysis of implants in partial edentulism, Prognosis Versus Actual Outcome. 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. Large-scale randomized controlled trials should be conducted to strengthen the evidence. The measurements were performed using computerized morphometry. Studies consistently show more periodontal disease and generally greater severity of disease in older as opposed to younger people. A random effects model showed weighted mean survival rates of 85.6% (95% confidence interval [CI], 76.7–91.5) for CR and RR procedures OVERALL. IV. Clinical implications are as follows. The impact of this lack of practice guidelines on the recommendation of surgery in clinical practice is unclear. Overall versus individual tooth prognosis, When projecting prognosis, many factors are to be evaluated. Dental implants, however, present a de novo situation and a functional period of at least 5 years is often required before peri-implant diseases are established and detected. Patient issues such as overall health, impacted medications, dental IQ, oral hygiene, etc., need to be assessed prior to dental therapies and reviewed at each exam and recall appointment. A need to appreciate advances across both disciplines is highlighted, allowing the development of effective interdisciplinary evidence -based treatment strategies to maximize treatment outcome. In the case presented, 2 old amalgam restorations on mandibular molars were replaced with endocrowns made of pressed ceramics (Empress 2, Ivoclar) following endodontic and periodontal therapy. With periodontal therapy, many teeth with an unfavorable periodontal forecast can be converted to teeth with a favorable long-term prognosis; therefore, caution should be taken when considering criteria for tooth removal. ] Key Method A search was conducted reviewing existing literature relating to classification and prognostication of individual teeth. Overall prognosis. To Conserve or Implant: Which Choice of Therapy? Conclusions The article will concentrate on the single tooth or implant restoration. Other reasons for tooth loss accounted for only 20.2% of the series. Many etiologic factors can lead to the loss of a tooth. These authors and others (7) reported that endodontists showed the most consistent agreement among themselves compared with the other specialty groups in the study. The global prognosis predicts the general outcome for the case, and individual tooth prognoses only predict the outcome for the individual tooth. All available clinical studies from 1981 to 1997, published in English or with English abstract, that presented success/failure data regarding implant treatment were evaluated to determine the types of reported complications and to quantify implant loss as it relates to type of prosthesis, arch, time, implant length, and bone quality. Patients were placed on a 3-month interval for maintenance prophylaxis and had yearly periodontal scorings for a period of 8 years. A study was done to evaluate long-term results of treating 387 maxillary molars with furcation involvement in 100 patients with chronic destructive periodontal disease. • Diabetes. A number of 4,804 implants were initially placed, of which 74 failed, with a majority of failures (74%) within the first 12 months. The prognosis of the tooth is affected by a number of factors including the quality of the root canal treatment, the quality and quantity of the remaining coronal tooth structure, the avoidance of iatrogenic accidents such as perforation during post-space preparation, and the physical characteristics and fit of the core and the definitive restoration (Fig 8-1). 6. Long-term implant prognosis: Although implant treatment success rates are very high during the first years, there is a question about the biological complications that appear after 5 years of function [31,32]. 3) Having fewer anterior occluding pairs had a greater negative impact on aesthetics and thus affected OHRQoL.

Introduction A prospective study of the factors affecting outcomes of nonsurgical root canal treatment: part 1: periapical health. Successful dental implantation depends on an osseointegration phenomenon, a direct structural and functional binding reaction between bone and implant. The analysis of the current literature aimed at clarifying which if the two treatment options leads to improved survival and success rates. This information will help the clinician develop the treatment options suitable for tooth replacement. Abstract. 2008). Recommendations presented are based on best available evidence from the literature and the expert views of specialists in endodontics and restorative dentistry, including dental implantology. The present study aims at assessing the factors influencing long-term prognosis of autotransplanted teeth with complete root formation. Based on selected follow-up studies that offer the best evidence, the chance of teeth without apical periodontitis to remain free of disease after initial treatment or orthograde retreatment is 92 percent to 98 percent. the need for post-core restorations is also reduced. The time of implant loss (preprosthetic vs postprosthetic) varied with type of prosthesis. In conclusion, it was found that projections were ineffective in predicting any prognosis other than good, and that prognoses tended to be more accurate for single rooted teeth than for multi-rooted teeth.

Another system was introduced by Kwok and Caton, which determines prognosis on future periodontal stability.1,6 Prognosis is considered “favorable” for teeth when the local or systemic factors can be controlled and the periodontal status of the tooth can be stabilized with comprehensive periodontal treatment and maintenance. Most individuals with CMT have some amount of physical disability, although some people may never know they have the disease. The objective of this review of literature is to discuss relevant factors associated with patient’s health, tooth and dentist that could account for a successful RCT. Abstract. Hand searches were conducted of the bibliographies of related journals and systematic reviews. Numerous other factors need to be considered when deciding whether to save or extract a tooth in the esthetic zone: restorability, disease susceptibility, papillary and gingival considerations, tooth esthetics, etc. About this Attention Score In the top 25% of all research outputs scored by Altmetric. Initial and long-term marginal bone changes were identified. If endodontic therapy is required, additional issues need to be reviewed before initiating treatment, including restorability of the tooth, presence of a large periapical area, use of the tooth as an abutment, etc. Considering the favorable outcome, conservative endodontic therapy, both nonsurgical and surgical, is definitely justified and should be attempted when a good restorative and periodontal prognosis is projected, unless the patient is not motivated to retain the tooth. Full size table. © 2008-2020 ResearchGate GmbH. Six prognostic factors that could be quantitatively evaluated were selected to be scored: age, probing depths, furcation involvement, mobility, molar type, and smoking. To date there are no clinical studies available that directly compare survival rates of teeth undergoing apicoectomy and implants. There was greater loss in the maxilla than mandible with fixed complete dentures and overdentures, whereas little arch difference was noted with fixed partial dentures. The combined effect of IL-1GP and heavy smoking increased the risk of tooth loss by 7.7 times. However, the type of treatment was found to be significant. In this era of increased dental implant use, there is a tendency to underestimate the long-term prognosis of a tooth with a compromised periodontium (treated or untreated). An understanding of the patient's needs and the length and likely success of treatment guides the decision of whether to preserve teeth or extract them and place implants. Since periodontal diseases are multifactorial, knowledge of the patient's genotype is more important in predicting future risk than explaining past disease. Conclusion: Five peer-reviewed journals, references of relevant publications, and reviews were hand searched. Eighty-four per cent of the failures occurred after 5 years. There was perceptible increase in bone loss in 41 teeth (11%). • For example, in a patient with a poor overall prognosis, the dentist likely would not attempt to retain a tooth that has a questionable prognosis because of local conditions. A regular clinical and radiological follow-up should be mandatory for at least a period of 1 year. 1.9.2 Overview of prognostic factors for resolution of periapical disease by root canal treatment 51 1.9.3 Overview of prognostic factors for survival of teeth after primary or secondary root canal treatment 71 1.10 Conclusions of the literature reviewed 78 1.11 Aims and objectives of the present study 79 A prospective study of the factors affecting outcomes of nonsurgical root canal treatment: part 1: periapical health. The mortality of teeth which were treated with periodontal surgery was compared with that of teeth which did not have surgery. The 2013 longitudinal study by Tada et al56 about the prognostic factors affecting the survival period of abutment teeth of removable partial denture evaluated 147 patients provided with 236 new RPD (846 analyzed abutment), finding out that the survival rate of direct, indirect and no abutment teeth to 5 years was 86.6, 93.1 and 95.8% respectively. A complete list of references is available from the publisher. Data were submitted the weighted least-squared analysis. While many considerations from the periodontal literature apply, new information and techniques should be considered to retain teeth or not.2. The lowest incidence of clinical complications was associated with all-ceramic crowns (8%). A random sample of 30 general dental practitioners (GDPs) from a list of 300 GDPs (1:10) was contacted. Individual data showed weighted mean survival rates of 81.9% (95% CI, 72.0–88.8) for CR and 87.2% (95% CI, 71.7–94.8) for RR. This is particularly true if recession will be induced. ... Outlook (Prognosis) Everyone heals at a different rate. Aim To investigate the probability of and factors influencing periapical status of teeth following primary (1°RCTx) or secondary (2°RCTx) root canal treatment. Factors that affect individual tooth prognosis and choices in contemporary treatment planning. Criteria for predicting the prognosis of patients with lung cancer-derived metastatic spine tumors (maximum total score 6 points). Twenty-four patients were selected from The University of Michigan longitudinal periodontal clinical trial.
