Background/Objectives: The use of titanium meshes in bone regeneration is a clinical procedure that regenerates bone defects by ensuring graft stability and biocompatibility. The aim of the present investigation was to evaluate the clinical effectiveness of titanium mesh procedures in terms of vertical bone gain and the exposure rate. Methods: The product screening and eligibility analysis were performed using the Pubmed/MEDLINE, EMBASE, and Google Scholar electronic databases by two authors. The selected articles were classified based on the study design, regenerative technique, tested groups and materials, sample size, clinical findings, and follow-up. A risk of bias calculation was conducted on the selected randomized controlled trials (RCTs) and non-randomized trials and a series of pairwise meta-analysis calculations were performed for the vertical bone gain (VBG) and exposure rate. A significantly lower exposure rate was observed using coronally advanced lingual flaps (p < 0.05). No difference was observed between the titanium mesh and GBR techniques in terms of VBG (p > 0.05). Results: The initial search output 288 articles, and 164 papers were excluded after the eligibility analysis. The descriptive synthesis considered a total of 97 papers and 6 articles were considered for the pairwise comparison. Conclusions: Within the limits of the present investigation, the titanium mesh procedure reported high VBG values after the healing period. The mesh exposure rate was drastically lower with passive management of the surgical flap. Full article

Background/Objectives: Preclinical training in pediatric dentistry is traditionally performed on acrylic primary teeth or natural extracted teeth in phantoms or dental manikins. With technological advancements, virtual simulation has become increasingly common, enhancing the development of cognitive and motor skills in dental students while complementing traditional methods. Specific objectives included assessing whether preclinical theoretical knowledge impacts motor skill scores, comparing the quality of dental preparations on acrylic teeth versus those performed using virtual simulation (Simodont^®) and evaluating students’ perceptions of Simodont^® use. Methods: An observational, descriptive, cross-sectional study was conducted. Students first completed a theoretical knowledge survey on dental preparations, class II caries, and pulpotomies. They then performed dental preparations on both acrylic primary teeth and the Simodont^® simulator, with their work assessed by a pediatric dentistry professor. Finally, students completed a perception survey regarding their experience. Results: The introduction of the Simodont^® was positively received. Theoretical knowledge prior to preclinical exercises did not significantly influence practice scores. Average scores for preparations on acrylic teeth (class II: 2.57; pulpotomy: 3.60) were higher than those achieved using Simodont^® (class II: 1.97; pulpotomy: 2.92). Conclusions: Dental preparation scores were higher on acrylic teeth compared to the virtual simulation. While students reported a positive experience with Simodont^®, they expressed a preference for traditional learning methods involving acrylic teeth on phantoms or dental manikins. Full article

Background/Objectives: The morphology of roots and root canals has a significant influence on the outcome of endodontic treatment. This study aimed to compare premolar root and root canal configurations between Central American and European subpopulations using cone-beam computed tomography (CBCT). Methods: This cross-sectional retrospective study analyzed CBCT scans of 2919 premolars from 561 patients: 197 from Jamaica (Central America) and 364 from Portugal (Europe). The analysis focused on the number of roots, root canal configurations, and the presence of C-shaped canals in mandibular premolars. Demographic factors such as age and sex were also considered. Statistical significance was determined using chi-square tests with a significance level set at p < 0.05. Results: Overall, premolars in Jamaican patients had more roots and root canals compared to those in Portuguese patients. Three-rooted configurations were more common in Jamaica, particularly in maxillary first premolars (5.5% vs. 2.9%, p < 0.05). Vertucci Type V configuration was more prevalent in the Central American subgroup, while Portuguese premolars were more likely to exhibit Types II and IV configurations. C-shaped canals were rare in both populations (p > 0.05). Males and younger patients showed higher frequencies of multi-root and multi-canal configurations (p < 0.05). Conclusions: This study reveals significant geographic and demographic differences in premolar root and root canal morphology between two Central American and European subpopulations. Premolars from Jamaica tend to exhibit more complex anatomical features compared to those from Portugal. These findings highlight the need for population-specific diagnostic and treatment strategies and demonstrate the value of CBCT in the preoperative diagnosis of complex anatomical variations.

Objectives: Endodontic instruments require thorough decontamination and sterilization before use and reuse to ensure the safety and success of treatments. However, standardized protocols are lacking. This study aimed to quantitatively assess the effectiveness of different cleaning protocols in removing debris from NiTi rotary file surfaces. Methods: Forty-eight new Mtwo NiTi rotary instruments (sizes 10/.04, 15/.05, 20/.06, and 25/.06) were randomly assigned to four groups (n = 12). A set of new sterile instruments (Group I) served as the negative control. After usage for primary endodontic treatment, instruments underwent different cleaning protocols: steam sterilization without cleaning (Group II); ultrasonic cleaning + steam sterilization (Group III); and manual cleaning with a scouring sponge + ultrasonic cleaning + steam sterilization (Group IV). Back-scattered scanning electron microscopy (SEM) micrographs of the apical, middle, and coronal sections were processed using Fiji software (version 2.14.0) to quantify debris as a percentage of the total selected area. Results: No significant differences were found among the three sections within each group, although higher debris amounts were observed from coronal to apical in Groups I and II. Group I had the least debris, while Group II showed the most, with statistically significant differences compared to other groups (p < 0.05). There was no significant difference between Groups III and IV, though Group IV showed notably less debris. Conclusions: The combination of mechanical, chemical, and ultrasonic cleaning proved most effective at removing debris from endodontic instruments. Current cleaning methods, however, remain insufficient for complete debris removal, highlighting the need for further research to standardize and improve cleaning and sterilization protocols or preferably use single-use/single-patient instruments.

Background/Objectives: The excessive consumption of free sugars adversely impacts health, contributing to systemic disorders and significantly increasing the risk of dental caries. Children are particularly vulnerable to dental caries due to their dietary habits and oral hygiene practices. This study aimed to examine the relationship between sugar intake and dental caries experience in a sample of children aged 6–12 years. Methods: Data were analyzed from the National Health and Nutrition Examination Survey (NHANES) covering the years 2011–2016. This cross-sectional study utilized nationally representative data from NHANES, which provides comprehensive health assessments on the U.S. population. This study focused on 3658 children aged 6–12 years. Free sugar intake and its association with dental caries were evaluated using the Decayed, Missing, and Filled Teeth (DMFT) index, a widely accepted measure for assessing cumulative caries experience in permanent teeth. Demographic and socioeconomic factors were also accounted for. The sample primarily consisted of generally healthy children, with mild to moderate health conditions included in the analysis. Results: The average Decayed, Missing, and Filled Teeth (DMFT) score was 1.69 (SD = 2.61). Untreated dental caries affected 19.1% of the sample, with disproportionately higher rates observed among Mexican American children (23.8%), children from lower socioeconomic backgrounds (24.2%), those with less-educated parents (25.1%), and overweight children (22.9%). Mean daily free sugar intake was 72.46 g (SD = 50.45), with significant variations across race/ethnicity, parental education, and gender. A statistically significant association was found between free sugar intake and dental caries in U.S. children (p < 0.001). Conclusions: Free sugar intake is strongly associated with an increased risk of dental caries. Disparities in caries prevalence were evident based on race/ethnicity, socioeconomic status, and parental education levels. Regulating sugar intake and promoting dietary education are effective strategies to reduce the risk of dental caries and improve oral health outcomes among children. Full article

Background/Objectives: The aim of this study is to investigate the side effects of two techniques of rapid maxillary expansion—Surgically Assisted Rapid Palatal Expansion (SARPE) and Miniscrew-Assisted Rapid Palatal Expansion (MARPE)—in adult patients, to guide the selection of the most cost-effective clinical treatment plan. Methods: The review protocol was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis—extension for Scoping Reviews (PRISMA-ScR) guidelines. Eligibility criteria were defined based on the study objectives. The research team formulated a PICO question to identify relevant studies in the literature. Five databases were queried: MEDLINE (via PubMed), Scopus, Cochrane Library, Web of Science, and Embase. Additionally, a manual search was conducted. Results: The computer-assisted search identified 746 articles, of which only 26 fully met the inclusion criteria and were included in the scoping review. Among the included studies, 11 were retrospective, 12 were prospective, and 3 were randomized clinical trials. SARPE was evaluated in 21 studies, MARPE in 4 studies, and 1 article reported complications associated with both techniques. The side effects described in the studies were synthesized and categorized into five groups: expansion failure, asymmetric expansion, dentoalveolar issues, surgical complications, and appliance-related problems. Conclusions: The results indicate that both techniques involve risks. The most reported adverse effects were dentoalveolar and surgical in nature. Dentoalveolar side effects, such as dental tipping, were predominantly associated with the MARPE technique, while surgical complications were more commonly observed with the SARPE technique. Patient age is crucial for treatment choice as well as proper design and planning of the expansion device. Consequently, careful patient selection and treatment planning are essential to minimize the side effects of maxillary expansion in adult patients. Full article

Objectives: Dental erosion has evolved into a common condition with growing concern in the dental community. The aim of this study was to explore the protective effects of two highly fluoridated products, silver fluoride solution (silver diamine fluoride-potassium iodide solution, SDF-KI) and fluoride varnish, on dental erosion in mouse. Methods: Two groups of ten young CD-1 mouse were given a cola drink ad libitum over a 6-week period. A prophylactic treatment with a silver fluoride solution (38% SDF 48,000 ppm F with a silver concentration of 253,900 ppm) and a fluoride varnish (NaF, 22,600 ppm F) were applied on the mandibular molars, performed under sedation twice a week during the whole experiment. Furthermore, two control groups of ten mice were included, a positive (cola drink) and a negative (distilled water) control. A terminal procedure was followed by dissection of mandibular molars and analysis of them using scanning electron microscopy (SEM). The first molars were transversely ground, further analyzed by SEM, and measured for tooth height and tooth tissue loss. Results: Analyses of mandibular molars treated with a fluoride varnish indicated a 5% decreased tooth tissue loss, compared to the molars which served as a positive control. The best effect was achieved with the application of silver fluoride solution, displaying a 35% decreased tooth tissue loss compared to the positive control group. Conclusions: Preventive treatment with a solution of silver fluoride solution exhibits greater protection against dental erosion compared to a traditional fluoride varnish. This study indicates that silver fluoride solution is an effective fluoride compound and is highly beneficial in a clinical setting with the aim of preventing dental erosion. Full article

Background/Objectives: Whiter teeth are widely accepted as the most beautiful. With the growing demand for whiter teeth, several manufacturers have launched different brands of whitening toothpaste claiming to be effective in removing tooth stains and whitening teeth. The objective of this in vitro study was to evaluate and compare the whitening effect of eight over-the-counter available toothpastes by measuring the changes in color using a digital colorimeter in a simulated staining–brushing cycle model. Methods: A total of 32 extracted bovine enamel were polished with 1000–2000 grit SIC paper and immersed in a tea staining solution for 30 min at 37 °C to create extrinsic staining. The specimens were randomly divided into eight groups (n = 4) and subjected to a staining–brushing cycle for 2 weeks. During this period, the specimens were stained for 5 min twice, brushed for 2 min twice per day, and immersed in artificial saliva for the remaining time. The colors of the enamel surfaces L*, a*, and b* were recorded, and the color difference (ΔE) was measured before the treatment and after 1 and 2 weeks of the staining–brushing cycle. Results: The repeated measures showed a significant reduction of (ΔE) after 1 week of the staining–brushing cycle in all eight experimental groups (p < 0.05). The (ΔE) was significantly reduced after the second week of the staining–brushing cycle in groups 1, 3, and 5 (p < 0.05). However, it was insignificant in groups 2, 6, 7, and 8 (p > 0.05). Among the tested materials, group 1 showed the highest and group 8 showed the lowest teeth-whitening effects. Conclusions: The over-the-counter toothpaste used in this study showed effective teeth-whitening. Charcoal-based toothpaste showed the highest efficiency in teeth whitening. Full article
