This study evaluated the long-term cost-effectiveness of five treatment alternatives for replacing a missing maxillary lateral incisor: single-tooth implant-supported crown, resin-bonded fixed partial denture, cantilever fixed partial denture, full-coverage fixed partial denture, and autotransplantation. The costs and 10-year survival rates of each treatment were analyzed. Autotransplantation was found to be the most cost-effective option, while full-coverage fixed partial dentures were the least cost-effective. However, other factors like a patient's age, dental condition, and preferences should also influence treatment choice.
This review paper analyzed 1300 publications in the Journal of Maxillofacial Oral Surgery from 2009 to 2020 to evaluate trends in levels of evidence. The analysis found that case reports and narrative reviews with a level D evidence accounted for 36% of publications. The majority (35%) of articles fell under maxillofacial pathology. The percentage of higher levels of evidence (A and B) increased from 2.09% in 2009/2010 to 12.74% in 2019/2020, indicating improving research quality over time. Categorizing publications by level of evidence and topic can help refine research quality in the journal going forward.
Bleeding on probing : Asessment of different indicesNavneet Randhawa
This study compared quantitative and binary (presence/absence) indices for assessing dental plaque and gingival bleeding in clinical trials. The study found that both types of indices produced similar results, with marginal differences, in measuring reductions in plaque and changes in bleeding over time. Therefore, the study concluded that binary indices may be used effectively in daily clinical work without the extra time required for quantitative indices, though quantitative indices are still necessary for more detailed clinical/epidemiological trials.
Marginal and Internal Fit of Different Fixed Dental Prostheses: A Comparative...DrHeena tiwari
This study compared five methods for assessing the marginal and internal fit of fixed dental prostheses: the cross-sectional method, silicone replica technique, triple scan method, micro-computed tomography, and optical coherence tomography. Measurements of the marginal gap, axial gap, angle gap, and occlusal gap found statistically significant differences between the methods. The cross-sectional method and silicone replica technique showed the lowest mean values and were the most similar, while the triple scan method and optical coherence tomography also showed similarities. The study concluded that while fit values may fall within clinically acceptable ranges, differences between assessment methods should be considered.
The document discusses patient selection criteria for different types of dental implants. It provides an overview of various implant types including endosseous, subperiosteal, and transosteal implants. Key factors for implant success like biomaterials, biomechanics, dental/medical evaluation, surgical requirements, healing processes and maintenance are reviewed. Indications and contraindications for different implant types are outlined based on bone quality and quantity, degree of edentulism, and practitioner training. Biomechanical principles for implant placement and prosthetic support are also covered.

The document assessed clinical outcomes of orthodontic cases treated with Roth and MBT bracket prescriptions using the American Board of Orthodontics Objective Grading System (ABO-OGS). Forty patients treated with either Roth or MBT brackets were evaluated based on post-treatment dental casts and panoramic radiographs using the ABO-OGS scoring criteria. The MBT bracket group had significantly lower scores for buccolingual inclination and occlusal contact. The total ABO-OGS score was also lower for MBT by 2.65 points, though the clinical significance was small. Both bracket prescriptions produced similar clinical outcomes with quality depending more on clinician skill than prescription.
Hospital-acquired pressure injuries are a significant issue, costing $11 billion annually in the US. A fishbone diagram was used to identify multiple factors that influence pressure injury development, including patient characteristics, materials, staff, processes, environment, and methods. Evidence shows that involving patients in their own care through education on positioning, mobility, and prevention can help reduce injuries. Evaluating prevention strategies and pressure injury rates through staff meetings and assessing staging can help hospitals improve processes and decrease injuries over time.
Endodontic treatment and tooth extraction with dental implant placement are two main treatment options for a diseased tooth. There are numerous factors to consider when deciding between the options, including prognosis, risks and benefits, costs, and the patient's medical history and preferences. While implant survival rates are high in the short term, endodontic treatment has shown positive survival rates in both the short and long term. Additionally, endodontic treatment preserves the natural tooth and soft tissue, which is important for aesthetics. The optimal treatment must consider all relevant factors and the patient's best interests.

2009 A novel decision making for tooth extraction or conservation.pdfKaterineRiquelme3
This document presents a decision-making chart to help clinicians determine whether to extract or retain a compromised tooth. The chart contains 6 levels of factors to consider, ranging from initial patient assessment to periodontal disease severity. Each factor is assigned a color (green, yellow, red) to indicate the likelihood of successful long-term retention. If a tooth receives mostly red or a combination of red and yellow ratings, extraction is recommended. The chart is meant to guide clinicians through an analysis of all relevant factors to make the best decision for each individual tooth and patient.
This meta-analysis evaluates the reliability of published evidence on regenerative endodontic procedures. It summarizes clinical and radiographic findings from studies on treating non-vital immature permanent teeth using regenerative techniques. The analysis finds good success rates for tooth survival and pathology resolution, but variable results for outcomes like apex closure and root development. Regenerative procedures are improving but factors important for success remain unclear, indicating more research is needed.
This document summarizes a critical appraisal of a study that evaluated the long-term cost-effectiveness of different treatment options for replacing missing maxillary lateral incisors. The treatment options considered were single tooth implant crowns, resin bonded fixed partial dentures, cantilever fixed partial dentures, and autotransplantation. The study found autotransplantation to be the most cost-effective option and fixed partial dentures the least effective, based on a cost-effectiveness ratio of survival probability to treatment fee. However, the critical appraisal notes several limitations, including a lack of statistical analysis and contradictory statements between the results, discussion and conclusions.
This study assessed the 5-year outcome of apical microsurgery in 170 teeth from 191 subjects who underwent the procedure. At the 5-year follow-up, 129 teeth (75.9%) were healed compared to 83.8% at 1 year. Two significant predictors of healing outcome were identified: teeth with interproximal bone loss >3 mm from the cementoenamel junction had a lower healing rate (52.9%) compared to those with ≤3 mm bone loss (78.2%); and teeth filled with ProRoot MTA had a higher healing rate (86.4%) than those filled with SuperEBA (67.3%).
Root canal treatment and dental implants are both viable treatment options for replacing missing or compromised teeth. Success rates of each treatment are generally high, ranging from 92-97% for root canals and 95-99% for implants. Other factors beyond success rates must be considered, including patient characteristics, habits, concerns, and costs. Overall, both treatments can successfully restore oral function but root canals may involve fewer complications and costs compared to implants. The decision requires weighing risks and benefits based on the individual clinical situation.
Introduction. The differences in the supporting structure of the implant make them more susceptible to inflammation and bone
loss when plaque accumulates as compared to the teeth. Therefore, a comprehensive maintenance protocol should be followed
to ensure the longevity of the implant. Material and Method. A research to provide scientific evidence supporting the feasibility
of various implant care methods was carried out using various online resources to retrieve relevant studies published since 1985.
Results.The electronic search yielded 708 titles, out of which a total of 42 articles were considered appropriate and finally included
for the preparation of this review article. Discussion. A typicalmaintenance visit for patients with dental implants should last 1 hour
and should be scheduled every 3 months to evaluate any changes in their oral and general history. It is essential to have a proper
instrument selection to prevent damage to the implant surface and trauma to the peri-implant tissues. Conclusion. As the number
of patients opting for dental implants is increasing, it becomes increasingly essential to know the differences between natural teeth
and implant care and accept the challenges of maintaining these restorations.
Int Endodontic J - 2022 - Kvist - Clinical decision making of post‐treatment ...DrDipaliShah
This document discusses clinical decision making regarding post-treatment disease in root-filled teeth. It begins by noting that 25-50% of root-filled teeth show signs of post-treatment disease on radiographs, though many are asymptomatic. There is no consensus among clinicians on how to manage such cases. The document outlines the typical options of no treatment, monitoring, extraction, or retreatment via surgical or non-surgical methods. It discusses how decisions are inherently subjective based on a clinician's knowledge and experience. Descriptive research has found wide variation in how clinicians decide to manage individual cases. The concept of "success" and "failure" integrates biological, evaluative, and normative components, but health and disease exist
Congenital absence of maxillary lateral incisors is a frequent clinical challenge which must be solved by a multidisciplinary approach in order to obtain an
esthetic and functional restorative treatment. . Fixed prosthodontic and removable prostheses, resin bonded retainers, orthodontic movement of maxillary
canine to the lateral incisor site and single tooth implants represent the available treatment modalities to replace congenitally missing teeth. This case report
demonstrates the team approach in prosthetic and surgical considerations and techniques for managing the lack of lateral incisors. The aims of this case

This randomized clinical trial compared the survival of composite resin restorations and metal-ceramic crowns on endodontically treated teeth over a follow-up period of 1 to 5 years. 57 restorations were placed in 47 patients, with 30 being composite resin and 27 being metal-ceramic crowns. One tooth was extracted in the composite group due to root fracture. There were 8 failures in the composite group and 1 failure in the crown group, mostly due to secondary caries or restoration fracture. Metal-ceramic crowns demonstrated better clinical performance and lower need for re-intervention, but both types of restorations showed good survival rates with no significant difference.
Aims: This study evaluated the subjective experience of masticatory performance and masticatory efficiency in partially edentulous patients rehabilitated with three different types of removable partial dentures (RPDs). Materials and methods: This was a crossover randomized study, which was carried out at the prosthodontics clinic of the University of Ghana Dental School clinic. Sixteen patients requiring RPDs but had never worn one before were consecutively recruited for the study. Three different RPDs [i.e., cobalt chromium, acrylic, and thermoplastic resin (iFlex)] were fabricated for each patient. Masticatory efficiency was assessed using a singlesieve method after chewing raw carrots. The subjective experience of masticatory performance was also assessed using a questionnaire after 1 week of using each denture. Results: The cobalt-chromium denture recorded the highest masticatory efficiency (31.4%), and the iFlex denture recorded the lowest (27.9%).
This document summarizes a review of literature on patient-related risk factors for dental implant therapy. The review identified 43 relevant studies based on inclusion criteria. The studies contained confounding variables and small sample sizes in subgroups. Consistent evidence showed increased implant failure rates in smokers, patients with a history of radiotherapy, and those with poor local bone quality or quantity. Weaker evidence linked a history of periodontitis to higher peri-implant disease. A lack of evidence precluded guidelines for patients with autoimmune disorders. Emerging evidence suggests a correlation between genetic traits and disrupted osseointegration.
This document discusses standard straight-wire appliances versus individualized straight-wire appliances. It describes an individual patient (IP) appliance system that offers 250 bracket and band variations, 10 times more than standard appliances. The IP system uses computer software to design a unique appliance for each patient based on their specific diagnosis and treatment plan. It aims to eliminate wire bending and improve treatment results. The document presents two clinical cases treated with the IP system to demonstrate its advantages over standard appliances.

This study compared the effectiveness of Hawley retainers and two protocols for vacuum-formed retainers (VFRs) in maintaining orthodontic treatment results. 90 patients were randomly assigned to receive either a Hawley retainer, VFRs worn for 4 months full-time then nightly, or VFRs worn for 1 week full-time then nightly. Models at debond and 4 and 8 months post-treatment showed the Hawley group had significantly greater loss of upper arch length and increased crowding compared to the VFR groups, though lower arch measurements were similar. Both VFR protocols were more effective than Hawleys in maintaining the upper arch, and 4 months full-time wear provided better lower incis

The authors discuss strategic considerations in treatment planning and deciding whether to treat, extract, or replace a questionable tooth. They summarize key prognostic factors from a periodontal, endodontic, implant, and prosthodontic perspective. Factors that indicate a tooth has a good prognosis include a probing pocket depth of ≤5mm, no bleeding, and <50% attachment loss. A questionable prognosis is indicated by a probing pocket depth ≥6mm, bleeding, and >50% attachment loss. Extraction is recommended for teeth with insufficient attachment or that are symptomatic with ongoing issues. The authors recommend preserving teeth when possible due to strategic value and preservation of gingival structures, but extracting teeth with a poor long-term prognosis.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
