Background: The aim of this study was to investigate the long-term effects of chemotherapy on the dental and gingival health and dental disturbance parameters of children cancer survivors. Procedure: Thirty-eight children (mean age 12.2 ± 0.5 years) who underwent chemotherapy at 4.29 ± 1.71 years of age formed the study group. Forty age- and gender-matched healthy children with a similar socioeconomic background served as controls. Subjects’ caries status (number of decayed, missing, or filled permanent teeth [DMF-T]) was recorded according to World Health Organization criteria. Subjects’ periodontal status was recorded according to the community periodontal index system. Radiographic dental examination was used to analyze dental malformations. Results: DMF-T, D-T (number of decayed permanent teeth), and F-T (number of filled permanent teeth) were significantly higher in the study group compared to the controls (4.61 ± 3.71, 3.97 ± 4.45, respectively, and 0.58 ± 0.14 vs. 2.21 ± 1.01, 0.84 ± 1.82, and 1.18 ±1.07, respectively. The most frequent dental disturbances were root malformation (52.6%) and agenesis (47.4%). Conclusions: According to our examination dental status of long-term survivors is worse than in controls. Hence proper oral hygiene for children cancer survivors (CCS) is critical. In order to meet the need for dental care in CCS health authorities are encouraged to revitalize the dental services Long-term follow-up of CCS is necessary to monitor their dental growth and oral health.

Periodontitis is the irreversible destructive process of the periodontium and is the major cause of tooth loss in adults worldwide. Diagnosis of early-stage periodontal disease is crucial for improving outcomes, and to this end, the application of indicator biomarkers is gaining interest. One such method involves measuring the level of matrix metalloproteinase-8 (MMP-8). This systematic review and meta-analysis aims to evaluate the salivary MMP-8 level of periodontitis and gingivitis cases compared to healthy controls. We evaluated all studies that compared different laboratory techniques for measuring salivary MMP-8 levels in periodontitis and gingivitis patients, alongside healthy controls. The systematic search was performed on 10 October 2022 in three electronic databases. Pooled mean differences (MD) were calculated with 95 % confidence intervals (CIs) between the researched groups. In addition, the correlation coefficient results between MMP-8 values and other clinical parameters were narratively summarized. Based on 20 eligible studies (n = 1725), patients with periodontitis presented significantly higher MMP-8 levels (MD = 273.26 ng/ml, CI: 194.42; 352.10). Similarly, patients with gingivitis presented significantly higher salivary MMP-8 levels than healthy individuals (MD = 122.82 ng/ml, CI: 64.19; 181.45) based on the results of 10 eligible studies (n = 704). Additionally, we found higher MMP-8 levels in periodontitis compared to gingivitis (MD = 112.04 ng/ml, CI: 56.15; 167.92). The correlation results suggest that salivary MMP-8 is associated with different clinical periodontal parameters. Salivary MMP-8 level measurement may be a reliable method to distinguish between periodontal health and periodontal disease and also to distinguish between gingivitis and periodontitis. The measurement of salivary MMP-8 levels may have the potential to differentiate between periodontal health and disease reliably. Accordingly, it can be considered for integration into routine dental examinations as a quick and convenient method for the early detection and prevention of periodontitis, pending further validation.

Statement of problem. Technical complication rates of standard metal-ceramic implant-supported posterior restorations are relatively high. Whether monolithic zirconia crowns represent a more successful alternative is unclear. Purpose. The purpose of this systematic review and meta-analysis was to compare the clinical outcomes of posterior monolithic zirconia and metal-ceramic implant-supported single crowns. Material and methods. A search was conducted in MEDLINE, Scopus, Embase, Web of Science, and CENTRAL databases for randomized controlled trials up to April 2023 with a follow-up time of at least 1 year. Restoration and implant survival and failure rates, marginal bone loss (MBL), bleeding on probing (BOP), and technical complications were analyzed by 2 reviewers. Statistical analyses were conducted using the R-statistics software program. The risk of bias was assessed by the Cochrane Risk of Bias Tool 2 (RoB 2), and the certainty of evidence by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Results. A total of 11 out of 2030 records were identified by title and abstract, and 4 records were included after full-text analysis. The statistical analysis revealed no significant difference in MBL (MD- 0.11, 95% CI: [-0.25; 0.03]), BOP (OR 0.66, 95% CI: [0.25; 1.77]), or implant failure (OR 1.30, 95% CI: [0.24; 7.08]). Monolithic zirconia presented significantly less chipping over 1 year (OR 0.17, 95% CI: [0.03; 0.99]). The chipping rate was 0% for monolithic zirconia and 7.61% for metal-ceramic. Based on a narrative review, the restoration survival rate was 97.5% in the monolithic zirconia group and 99.1% in the metal-ceramic group. Conclusions. Monolithic zirconia showed favorable short-term survival rates and had significantly less chipping over 1 year. Regarding MBL, BOP, and failure rates, both restoration types presented similar results at the 1-year follow-up. (J Prosthet Dent 2024;132:881-9)

Background: The era of digitalization has arrived in the field of dentistry. Teledentistry (TD), the use of digital solutions in dentistry, is already used in practice; however, only some possibilities are considered. During the COVID-19 pandemic, remote patient monitoring and patient communication had to be solved with TD, thus causing a rapid spread of new tools. In addition to digital workflows, patient communication, AI, and online forums are also available. Methods: An online self-administered survey was developed for the study. The Hungarian Medical Chamber contacted potential respondents in a newsletter or e-mail. The Evasys survey system was used. The weighting procedure was executed for gender, age group, and type of settlement. A digital dental index variable was created and built with a linear regression model as a dependent variable. Explanatory variables are advantages, disadvantages, what would be necessary, experienced needs from the patients, and age. Results: A total of 171 dentists completed the survey. The best-known digital technologies are online conferences (96.5%), E-prescriptions (94.6%), and digital impressions (86.0%). Unawareness is the highest in the field of artificial intelligence in dentistry (50.5%), store-forward solutions (43.5%), and real-time solutions (41.8%). The digital dental index is 14.24 (standard deviation (SD) = 5.5), with a high power of the model. Conclusion: Hungarian dentists need to be made aware of all the possibilities of TD. In addition to digital workflows, store-forward and real-time solutions can be beneficial to substitute face-to-face visits. TD can be used effectively to monitor oral cavity changes and develop dental confidence and proper oral care habits. Our survey suggests that it is necessary and inevitable to integrate TD into both graduate and postgraduate education, which may form the basis of primary health care in the next decade.

Background: Molar–incisor hypomineralization (MIH) is an enamel defect affecting molars and incisors, often leading to hypersensitivity, enamel breakdown, and increased caries risk. Non-invasive treatments, such as casein phosphopeptide–amorphous calcium phosphate (CPP-ACP) and fluoride varnish, show potential in remineralizing affected enamel and reducing sensitivity, but their efficacy is still debated. This study systematically reviews and analyzes the effectiveness of CPP-ACP and other non-invasive agents in improving remineralization and reducing hypersensitivity in MIH-affected teeth. Methods: A systematic search was conducted on PubMed, Embase, and Central in July 2024, including interventional and observational studies on remineralization and hypersensitivity in pediatric MIH patients (<18 years). A total of 1566 studies were found, with 15 included in the meta-analysis. A random-effects model was applied, including subgroup analysis by lesion severity. Results: CPP-ACP showed no statistically significant advantage over fluoride in remineralization (MD −3.80, 95% CI: −8.57; 0.98), but it significantly reduced hypersensitivity compared to fluoride varnish (MD −2.36, 95% CI: −3.83; −0.89). Although this reduction in hypersensitivity may be clinically relevant, the high heterogeneity (I² = 83%) and wide confidence intervals limit the reliability of these findings. Conclusions: CPP-ACP has a moderate effect in reducing hypersensitivity but does not outperform fluoride in remineralization. Other agents, such as calcium glycerophosphate and silver diamine fluoride, showed mild benefits. The current evidence base is limited and heterogeneous, highlighting the need for high-quality, long-term studies to confirm these findings and guide MIH management.

Background: The purpose of this in vitro study was to compare the accuracy of implant placement in model surgeries according to the design of the drills (straight drills or step drills) used to finalize the implant bed during pilot-guided static computer-assisted implant surgery (sCAIS). Methods: Model surgeries were carried out on resin models randomly assigned to three study groups. Virtual planning software (coDiagnostiX 10.6, Dental Wings, Montreal, Canada) was used to plan the implant positions. In Groups 1 and 2, pilot-guided sCAIS was performed. Straight drills were used in Group 1, and step drills were used in Group 2 to finalize the implant beds. In Group 3, fully guided sCAIS was performed using a universal fully guided kit (RealGUIDE Full Surgical Kit 3DIEMME, RealGUIDE, Cantù, Como, Italy). A total of 90 dental implants (Callus Pro, Callus Implant Solutions GmbH, Nuremberg, Germany) were placed (six implants per model, five models per study group). The primary outcome variables (angular deviation, coronal global deviation, and apical global deviation) were calculated for all implants based on the comparison of the preoperative surgical plan with the postoperative scans. Results: Group 2 (coronal global deviation, 0.78 ± 0.29 mm; apical global deviation, 1.02 ± 0.56 mm) showed significantly lower values of both global deviation variables than Group 1 (coronal global deviation, 0.95 ± 0.20 mm; apical global deviation, 1.42 ± 0.49 mm). However, there was no significant difference in angular deviation between Groups 1 and 2 (7.56 ± 2.92° and 6.44 ± 2.84°). Group 3 produced significantly lower values of all three primary outcome variables (angular deviation, 2.36 ± 0.90°; coronal global deviation, 0.59 ± 0.28 mm; apical global deviation, 0.90 ± 0.29 mm) than Group 1 and significantly lower angular deviation and coronal global deviation values than Group 2. Conclusions: The design of the drills used to finalize implant osteotomies during pilot-guided sCAIS influences dental implant placement accuracy. Using step drills instead of straight drills for final osteotomies decreases deviation from the surgical plan. The fully guided approach performed better than the pilot-guided sCAIS.
