Objectives: This study aimed to compare clinical results between titanium (Ti), zirconia (Zr), or titanium–zirconium (TZ) dental implants and to analyze survival rate (SR), bleeding on probing (BoP), marginal bone loss (MBL), and/or probing depth (PD). Data source: Manual and electronic searches were conducted (PubMed and Web of Science) to identify randomized controlled trials that compared the outcomes of at least two implant types (control and test group) within the same study. The focused question was determined according to the PICOT strategy. Seven studies were included out of 202 research studies initially found. The follow-up periods ranged from 12 to 80 months, and the mean age was from 43.3 to 65.8 years old. The SR for Ti, TZ, and Zr implants ranged from 92.6% to 100%, 95.8% to 100%, and 87.5% to 91.25%, respectively; MBL for Ti, TZ, and Zr implants varied from −1.17 mm to −0.125 mm for Ti, −0.6 mm to −0.32 mm for TZ, and −0.25 mm to −1.38 mm for Zr. Studies showed a low incidence of mucositis and peri-implantitis; however, BoP for Zr was 16.43%, Ti ranged between 10% and 20%, and TZ from 10% to 13.8%. PD for Ti ranged from 1.6 mm to 3.05 mm, TZ was 3.12 mm (only one study), and Zr ranged from 2.21 mm to 2.6 mm. Conclusion: All three types of implants showed similar tissue behavior. However, the TZ group had better results when compared with Ti and Zr for SR, MBL, and BoP, except for PD. Furthermore, the worst SR was found in the Zr implants group.
The purpose of this systematic review was to analyze sinus lifting procedures and to compare the efficiency of this treatment associated with the second generation of platelet-rich fibrin related to its effects on bone gain and to clarify the regenerative efficacy in sinus lift procedure, whether alone or as a coadjutant to other bone graft materials. The PICOT question was, “In clinical studies with patients needing a maxillary sinus lift (P), does the use of PRF either alone (I) or in conjunction with other biomaterials (C) improve the clinical outcome associated with bone gain and density (O), with at least three months of follow-up (T)?” An electronic search was conducted in the MEDLINE (PubMed), Science Direct, and Scopus databases through a search strategy. A total of 443 articles were obtained from the electronic database search. Sixteen articles met all criteria and were included in this review. Within the limitation of this study and interpreting the results carefully, it was suggested that a higher risk for implant failure after a sinus elevation might be seen in patients with residual bone ≤4 mm, and PRF application was effective, suggesting reducing the time needed for new bone formation.
This short communication aimed to acquire and transmit information about inserting CAD/CAM technology in the dental school’s curriculum to better prepare dental students for new approaches. The CAD/CAM system implementation has occurred slowly in the dental curriculum at universities. In 2012, authors evaluated the use of CEREC, showing an educational tool impacting the cost-effectivity for patients. A similar result was found in 2013, with an appreciation of the marginal fit and esthetic obtained. In 2014, CAD/CAM was incorporated into the predoctoral curriculum at the Indiana University School of Dentistry, showing good or excellent overall learning. In 2017, a CAD/CAM system was implemented at the University of Illinois at Chicago College of Dentistry’s predoctoral implant program, which had an increased preference and proportion of implant restorations made digitally. In 2018, a German dental school used CAD/CAM in the curriculum of prosthetic education, obtaining a clear tendency for the use of this technology. In 2023, pre-doctoral dental students in the U.S.A. received a questionnaire that significantly improved their knowledge and attitude to using this technology; otherwise, student satisfaction was non-significant. In conclusion, integrating CAD/CAM technology into the curriculum has become an essential component of modern dental education.
Introduction: Many General Dental Practitioners run single handedly a mini-hospital. Practice administration, delivery of treatment and financial stewardship are all demanding with consequent induction of uncertainty, distress, and diminished performance, loss of satisfaction and unwelcome depression and anxiety. Aim: This contribution describes moderation of stresses in general dental practice by applying amelioration policies. Discussion: This advisory is targeted at all dentists involved in extensive dental therapy. The stress and anxiety of practice management is improved by applying newly established principles of practice, namely the Initial Assessment and Ranking of Treatment Index (IARTI) and What arrangements Have you made to meet your Oligations (WAHUM TOMYO), Immediate Payment Therapy (IPP) and Big Toe Philosophy (BTP). Conclusion: By applying these fundamental principles into general dental practice, much anxiety is relieved, challenges and problems are avoided or resolved and successful practice of dentistry is realized. A much higher frequency of failures will occur if these principles are not applied. Success does depend on applying IARTI and WAHUM TOMYO, IPP and BTP.
Introduction: Dental erosion from acid drinks is known; in vitro with in vivo evidence that apple and grape juices cause erosion is rare. Aim: i) To test acidity (pH and buffering capacity) in vitro; ii) And assess if these juices leach calcium from teeth in vivo. Methodology: First: Six commercially available potable apple and grape juices were measured (six times each drink) for pH and buffering using 0.5 Molar NaOH with a Mettler DL 25 Automatic Titrator. The apple and grape juices were measured separately, using a 50 mL bolus for measures, 6 times for each. Second: Two volunteer cohorts; (One fully dentate WITH TEETH (mean age 20, M:F 6:6, n = 12) the second edentulous WITHOUT TEETH (mean age 61, M:F 6:6, n = 12), were used to swish with 50 mL aliquots of Apple and/or Grape juices for 30 seconds. Each sample was analyzed six times with Inductively Coupled Plasma with Optical Emission Spectroscopy (ICP-OES) for Calcium, and Phosphorous. Juices from source were analyzed for Calcium, and Phosphorous, and post-swish expectorate samples were analyzed for Calcium and Phosphorous. Data were analyzed 'blind' by technicians unaware of the source of procured samples. Results: Analysis reveals apple and grape juices have pH below 5.5. Statistics consistently show significant (p < 0.01 Student-t paired data) increases in Calcium and Phosphorous leeched from dentate (WITH TEETH) subjects after swishing with apple and grape juices tested. Results provide strong evidence that rinsing with Apple or Grape juices will erode teeth. Grape is more erosive than apple juice. Conclusion: Apple and grape juices have acidity below critical pH 5.5; Both have strong buffering capacities and will decalcify teeth by erosion, when exposed to these drinks in diets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
