factors affecting individual tooth prognosis

It also prevents interferences with periodontal tissues, thanks to a supragingival position of the restoration margins. 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. Compared to conventional methods, good aesthetics, teeth (ETT) has been widely and controversially Further evaluation of the data is needed to determine how each of the prognostic indicators relate to the success or failure of our projection. This article describes the rationale and clinical guidelines for the placement of endocrowns. 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. Characterization of Successful Root Canal Treatment A factor only becomes a part of standard practice after a great deal of research has shown it’s accurate and reliable. Prognosis should primarily have a scientific and evidence-based approach that also is predicated upon clinical experience, individual patient factors and luck. A total of 366 (94%) of the teeth did not have endodontic therapy before, during, or after the study. As far as the type of tooth was concerned, the most frequently extracted teeth were molars followed by premolars, regardless of whether their loss was the result of the caries or the periodontal disease. Inherent to reviewing the outcome is a definition of "success" in relation to the goals of therapy. This study investigated the prognosis for successful endodontic treatment and the correlation between the size of the periapical lesion, the quality of the root canal treatment, and the type of coronal restoration. Clinical trials were selected that addressed the ability of commonly used clinical periodontal parameters to predict disease progression leading to tooth loss. Periodontal disease appears to be bilaterally symmetrical and tooth loss response emulated this pattern with greatest loss of maxillary second molars and least loss of mandibular cuspids. The results of treatment were directly dependent on the preoperative status of the pulp and periapical tissues. Prognosis 2. In a further analysis of the current literature it became apparent that the long-term survival prognosis of teeth which underwent apicoectomy was questionable when additional systemic factors (e.g. During the post-treatment period, 300 patients had lost no teeth from periodontal disease, 199 had lost one to three teeth, 76 had lost 4 to 9 teeth and 25 had lost 10 to 23 teeth. A clinician evaluates a tooth for its quality of health. Personal and demographic information and clinical, Access scientific knowledge from anywhere. With single crowns, the 3 most common complications were need for endodontic treatment (3%), porcelain veneer fracture (3%), and loss of retention (2%). 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. 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. Prognosis can be stratified in the prognosis of the overall dentition and prognosis of individual teeth. 6. 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). This easy-to-use system assesses the condition of individual teeth and enables a relative prognostic value to be attached to those teeth based on tooth condition and patient-level factors. The radiographs of 292 teeth (75%) showed no significant change in bone support 5 to 24 years after treatement, while those of 8 teeth (2%) suggested improvement. Crown-root ratio is also a measure of attachment loss, especially when dealing with short roots. Varying numbers of teeth may be affected; After eruption, it … The purpose of the present study was to compare tooth mortality of root-resected molars with that of root-filled, single-rooted teeth. Your dentist may loosen the tooth in the gum using a tooth removal instrument called an elevator. The prognosis of the individual teeth is evaluated first on the basis of the overall prognosis and then on the status of each tooth according to pocket depths, attachment loss, mobility, amount and location of furcation involvement, tooth morphologic features, bone levels, general condition of the tooth, and ability to modify etiologic factors. Affected bone and other tissue may take a bit longer to heal. However, even with the lower chance of complete healing, the chance for the teeth to be functional over time is 86 percent to 92 percent. A multiple linear regression model was constructed for predicting initial prognosis based on initial clinical data. In cases in which the request appears influenced by a specific mental condition such as a phobia of dental treatment, extraction rarely is justifiable. Certain teeth or groups of teeth are prone to develop more severe periodontal destruction than other teeth in the same individuals. tooth implies understanding the biological and mechanical outcomes as multifactorial events over the individual’s life span. In this article, the authors offer guidelines to help dentists and oral surgeons make decisions regarding such requests for extraction. In order to calculate annual survival rates for individual studies a life-table analysis was conducted. Insurance did not play a role in the decision-making portion of the treatment plan. Diabetic patients have a higher prevalence of periodontal disease and greater attachment and bone loss.18,19 Patients with diabetes, especially poorly controlled diabetes, will generally have a worse overall prognosis than patients who are not diabetic (Fig. Methods 2). As with all diseases, a thorough history combined with comprehensive clinical and radiographic examinations are all required so an accurate diagnosis can be made. Sehr geehrte Anwender, die Anwendung "EVALuna Biblio" ist ab sofort unter https://evalunabiblio.uk-erlangen.de/EvalunaBiblio zu erreichen. Data were submitted the weighted least-squared analysis. Table 3 Multivariate analysis of the prognostic factors affecting survival. Most individuals with CMT have some amount of physical disability, although some people may never know they have the disease. It is likely, however, that the most important factor influencing the prognosis of endodontic treatment is the preoperative status of the teeth. embedImagecenter("Imagecenter_1_233",233, "large"); By Belinda Brown-Joseph, DMD, MS; Samia Hardan, DDS, MS; David L. Hoexter, DMD, FACD; Sebastien Dujardin, DDS, MS; and Jon B. Suzuki, DDS, PhD, MBA. 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. Although the literature presents considerable information on implant complications, variations in study design and reporting procedures limited the available data and therefore precluded proper analysis of certain complications. In the era of evidence-based dentistry, outcome studies have forced us to reexamine our treatment approaches and decide if superior treatment options should be pursued. Some teeth can have questionable prognoses, or be lost, and the … Key Method A search was conducted reviewing existing literature relating to classification and prognostication of individual teeth. 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. As the disease progresses, weakness and atrophy may occur in the hands, causing difficulty with fine motor skills. Genetic factors may play an important role in determining the nature of the host response. The diagnosis of a condition and knowledge of its etiology are essential to assess the prognosis of the remaining teeth and to formulate the correct treatment plan. The present study aims at assessing the factors influencing long-term prognosis of autotransplanted teeth with complete root formation. Once this is accomplished, the clinician obtains an estimate of longevity and decides whether to extract or to treat and maintain the tooth. The overall prognosis for treatment of periodontal pockets apparently is good for all tooth types and this observation applies to moderate as well as to deep pockets. • Genetics. Developing a prognosis for the dentition incorporates virtually all skills in the art and science of dentistry. 18. The Effectiveness of Clinical Parameters in Developing an Accurate Prognosis, Meta-analysis of implants in partial edentulism, Prognosis Versus Actual Outcome. Finally, when the prognosis is “hopeless,” extraction is indicated. The chance of teeth with apical periodontitis to completely heal after apical surgery is 37 percent to 85 percent, with a weighted average of approximately 70 percent. 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. A need to appreciate advances across both disciplines is highlighted, allowing the development of effective interdisciplinary evidence -based treatment strategies to maximize treatment outcome. The ideal restoration of endodontically treated In these cases it should be checked whether extraction and subsequent implant placement lead to improved long-term success. The endocrown is a restorative option for endodontically treated teeth. In a retrospective study, it has been shown that endodontically treated teeth show a survival rate after 12 months that is comparable to that of implants. Abstract. Factors that affect individual tooth prognosis and choices in contemporary treatment planning. In addition, smoking and increased initial bone loss were both found to be associated with increased risk of tooth loss while fixed abutment status was associated with a decreased risk of tooth loss. Resin-bonded prostheses (26%) and conventional fixed partial dentures (27%) were found to have comparable clinical complications incidences. The impact of this lack of practice guidelines on the recommendation of surgery in clinical practice is unclear. This study suggests that caries and its consequences are responsible for more tooth loss in patients less than 40 years of age while extraction because of periodontal problems increases with age, and more commonly related to pocketing. The article will concentrate on the single tooth or implant restoration. Factors affecting outcomes for single-tooth implants and endodontic restorations. Within each type of prosthesis, raw data were combined from multiple studies and mean values calculated to determine what trends were noted in the studies. Investigators were unable to judge which patients would be IL-GP or negative based on their clinical presentation or family history of tooth loss due to periodontal disease. On the other hand, ante-mortem factors including sex, age, tooth type, and tooth root portions did not reveal significant effect on dental DNA yield. The patients averaged 43.8 years of age and consisted of 59 females and 41 males. questionable possibility for adequate restoration of the clinical crown) had to be taken into account. 2008). If there was disagreement between the 2 specialists, they discussed all aspects of the case until a consensus was reached. The complex treatment of patients with advanced periodontal breakdown is very expensive.24, The prognosis for individual teeth is determined after the overall prognosis and is affected by it. Breast cancer stage is the most important factor for prognosis. This review describes practical criteria and a systematic process to aid the treatment planning decision of whether to preserve teeth by root canal treatment (RCT) or extract and provide an implant. The decision to extract a tooth will fluctuate depending on its clinical condition, and this action should be supported by the literature, clinical experience, and the patient's declared goals.
