Purpose: This systematic review aims to comprehensively assess the prevalence, extent, severity, and distribution of gingival recession (GR) among university students. Recognizing that GR rep-resents a significant periodontal concern with aesthetic and functional consequences, this review focuses on a young demographic that is underrepresented in epidemiological surveys.

Materials and methods: Following the PRISMA guidelines and a pre-registered protocol, a structured search strategy was designed and executed across PubMed, Web of Science, Cochrane, and EBSCO databa-ses, targeting studies published over the last 20 years. Eligibility was defined using the PICO framework: Population: university students; Intervention/Exposure: presence of GR; Comparison: absence of GR; Outcome: prevalence rates. The Joanna Briggs Institute (JBI) critical appraisal checklists were used to assess methodological quality and risk of bias across various study designs, including cross-sectional, cohort, case-control, and randomized controlled trials.

Results: Out of 299 initially identified articles, nine met the inclusion criteria, encompassing a total of 1,619 participants. The design of the included studies revealed considerable heterogeneity in sampling, measurement methods, and reported prevalence, which ranged widely from 29.4% to 82.6%. Risk factors linked to GR included age, gender, oral hygiene practices, brushing technique and force, occlusal interferences, and anatomical factors.

Conclusion: This systematic review demonstrates a high prevalence of gingival recession among university students, underscoring the importance of targeted preventive strategies and educational interventions in this population. Future well-designed longitudinal studies are needed to clarify causality and inform tailored prevention programs.

Purpose: Case reports are observational descriptive studies presenting unusual clinical conditions, rare disease occurrences, or introduction of novel treatment strategies. The present study aimed to identify and analyze 100 top-cited case reports/series in dentistry using bibliometric and science mapping analysis.

Materials and methods: The Web of Science database was used to retrieve top-cited case studies published in dentistry from inception until April 28, 2024. Basic bibliometric information was obtained. Biblioshiny and VOSviewer tools were employed to conduct thematic map and author keyword, title, and abstract terms analysis to elucidate the research trends. Elsevier Scopus and PubMed databases were used to crossmatch citations.

Results: The 100 top-cited case studies were published in 26 journals, originating from 25 countries, and collectively accumulated 23100 citations from 1967 to 2019. The citation counts ranged from 1368 to 123, 1673 to 41, and 1325 to 4 in the WoS, Scopus, and PubMed databases, respectively. The Journal of Periodontology first presented 20 articles and 4156 citations, followed by the Journal of Endodontics with eleven articles and 2247 citations. USA led in terms of countries while the University of Bern was the leading institution with 20 articles.

Conclusion: Although a great variation of the topics covered was documented, case reports in the field of dental implantology, periodontal regeneration, oral pathology, regenerative endodontic, and guided bone regeneration aspects had been the mainstay of the top-cited list.

Purpose: This study aimed to evaluate the effects of three final irrigation solutions with chelation properties [ethylenediaminetetraacetic acid (EDTA), novel silver citrate (NSC), and nanochitosan] on root canal dentin erosion and mineral content (calcium-to-phosphorus ratio (Ca/P ratio).

Materials and methods: A total of 28 premolars were used and assigned to four groups (n = 7): Group 1 17% EDTA; Group 2: NSC; Group 3: 0.2% nanochitosan; Group 4: saline (control). Each group was finally irrigated with a volume of 1 ml/min until the total final irrigation was performed for 5 min using a 30-gauge side vented needle, and the needle was inserted 1 mm shorter than the working length. Irrigation solution pH was netral. Each tooth was then divided into two parts: mesial and distal. The mesial section was evaluated for root canal dentin erosion, whereas the distal section was analyzed for the Ca/P ratio. Each section was evaluated at three levels (coronal, middle, and apical) of the root canal. Data on root canal erosion were analyzed using the Kruskal-Wallis and Mann-Whitney U tests, whereas the Ca/P ratio was analyzed using one-way ANOVA and Tukey's test.

Results: The EDTA-treated group exhibited the highest erosion, whereas the nanochitosan-treated group exhibited the lowest erosion of the root canal dentin (p<0.05). The nanochitosan-treated group exhibited the highest Ca/P ratio, whereas the EDTA-treated group exhibited the lowest ratio (p<0.05). The apical level had the highest Ca/P ratio but the lowest erosion compared with the other levels (p<0.05).

Conclusion: Nanochitosan demonstrated the lowest erosion and highest Ca/P ratio at all root canal dentin levels. Therefore, nanochitosan can potentially be used as a final irrigation solution.

Purpose: The aim of this study is to determine whether changes in the dimensions of the maxillary tuberosity influence the distalisation of maxillary teeth using mini-implants.

Materials and methods: Ten young orthodontic patients requiring mild to moderate proclination of the maxillary anterior teeth were studied. Distalisation of the maxillary teeth was achieved using a retractive force of 200 grams applied bilaterally to a 0.018"x0.022" stainless steel wire, with mini-implants located at the mucogingival junction. The dimensions of the maxillary tuberosity namely mesiodistal length, vertical height, and buccolingual width were measured using CBCT. The maxillary incisor proclination was measured on lateral cephalograms at T1 (before distalisation) and T2 (six months later). Statistical analysis included Spearman rank correlation analysis and Wilcoxon signed-rank tests.

Results: At T2, the mesiodistal length and the vertical height of the maxillary tuberosity showed a statistically significant decrease in dimension. The change in buccolingual width and the amount of anterior teeth retraction and distalisation of the first molar showed a statistically significant positive correlation suggesting that an increased remodelling of the maxillary tuberosity in the buccolingual dimension was associated with a greater magnitude of distalisation of the maxillary dentition. A positive correlation existed between the mesiodistal length at T1 and the amount of anterior retraction, suggesting that a greater mesiodistal length of the maxillary tuberosity at T1 corresponds to a greater amount of anterior retraction.

Conclusion: The dimensions of the maxillary tuberosity appear to influence the distalisation of the maxillary teeth with mini-implants.

Purpose: This study aims to examine the relationship between Google Trends (GT) data on orthodontics and oral hygiene terms from 2019, 2020, and 2021 and the gross domestic product (GDP) and population of cities in the Marmara Region.

Materials and methods: GDP, population, and GDP per capita data for Turkiye and the Marmara Region were collected. Using GT, searches for orthodontics, brackets, clear aligners, orthodontic toothbrush, toothpaste, and tooth decay were analyzed for 2019-2021. GT values for Turkiye and Marmara cities were recorded. The Kruskal-Wallis test was used for group comparisons, followed by Dunn's test for identifying significant differences. Spearman's rho correlation analysis assessed relationships between parameters.

Results: In 2021, the GT score for toothpaste was significantly higher than in 2019-2020 (p < 0.05). In 2019, clear aligner and tooth decay GT scores showed a positive, significant correlation with GDP (p < 0.05). In 2020 and 2021, braces, clear aligner, and tooth decay GT scores also correlated positively with GDP (p < 0.05). A consistent positive correlation between clear aligner and dental caries was observed across all three years (p < 0.05).

Conclusion: GT data demonstrate its potential as a valuable tool for epidemiological research, digital data management, and evidence-based analysis. Findings suggest that individuals in higher GDP provinces are more likely to search for advanced orthodontic treatment, particularly clear aligners.

Purpose: The aim of this study was to evaluate the reliability of the Frankfort horizontal (FH), sella-nasion horizontal (SN-h), optic, and orbitooccipital planes by assessing their variabilities relative to a true horizontal line (TrH) in Class 1, 2, and 3 patients.

Materials and methods: Eighty-one pre-treatment lateral cephalometric radiographs (LCRs) (27 each from Class 1, Class 2, and Class 3 based on ANB (°) were taken in the natural head position (NHP). NHP was created using a laser level creating the true vertical line and the TrH perpendicular to the true vertical. The inclinations of the anatomic reference planes were compared with the TrH.

Results: The orbitooccipital and FH planes were closest to the TrH, with mean values of -0.55 ± 3.26 and -0.60 ± 3.67, respectively. The mean value for the SN-h was 3.33 ± 4.40, whereas the mean value for the optic plane was 4.46 ± 4.58. The ranges were high for all anatomic planes: -9.03° to 8.22° for the FH plane, -8.79° to 6.49° for the orbitooccipital plane, -9.87° to 13.16° for the SN-h, and -4.21° to 16.43° for the optic plane. No significant differences were found in relation to skeletal patterns (orbitooccipital plane; p=0.05, FH plane: p=0.115, SN-h; p=0.156, optic plane; p=0.063, respectively). Regarding sex, there was a significant difference in the optic plane in only Class 1 females (p=0.024).

Conclusion: The FH and orbitooccipital planes are not the same TrH, but they are the closest reference planes. Variations in reference planes affect diagnosis and therapy.

Purpose: The aim of this study was to evaluate the effect of using an intraoral camera (IOC) as an educational aid for promoting oral health among 7-10-year-old children in India.

Materials and methods: A randomized trial was conducted involving 260 children from private schools. The intervention group (n = 130) received IOC-based oral health education, while the control group (n = 130) received verbal education. Both groups were assessed for knowledge, attitude, and practice (KAP) towards oral health, as well as the DMFT/deft index at baseline and after 12 months. Statistical analyses were performed using the Wilcoxon signed-rank test and the Mann-Whitney test. Additionally, regression analysis was conducted to predict DMFT and deft scores using KAP scores as predictors.

Results: A significant decrease (p<0.001) in the mean number of decayed teeth (dt + DT) was observed in both groups. However, the intervention group showed an increase in filled teeth (ft + FT) scores after 12 months. The experimental group also exhibited a significant increase in attitude scores (p<0.01) and practice scores (p<0.001). Despite these improvements, KAP scores did not predict the total caries experience, as no correlation was found between total caries experience (deft + DMFT) and KAP scores.

Conclusion: The use of the IOC as an educational tool significantly improved children's oral health status, as well as their attitude and practice scores. However, since KAP scores did not predict changes in oral health, a more comprehensive approach is required for effective oral health promotion among children.

Purpose: The aim of this study was twofold. First, it sought to compare the inter-canine distance measured on digital models generated by a digital scanner with those obtained from cast models made using alginate impressions of pediatric patients. Second, it aimed to compare the level of dental anxiety associated with the two impression techniques.

Materials and methods: The study population consisted of 50 patients aged 9-13 years who visited the Department of Pedodontics for dental treatment. Both alginate and digital impressions were taken consecutively for each patient. The five-point Facial Image Scale (FIS) was administered at baseline and after each impression technique. Pulse rate and oxygen saturation levels were measured, and the highest values were recorded. Inter-canine distances were measured on digital models, plaster casts, and intraorally (the latter serving as the gold standard). The two impression methods were compared in terms of dental anxiety and measurement accuracy. The Kruskal-Wallis H test was used to compare data between groups.

Results: Digital measurements were significantly higher than intraoral and alginate measurements, while intraoral and alginate measurements did not differ significantly. When FIS scores were compared, the alginate impression method resulted in higher mean scores than the digital method, indicating a higher level of dental anxiety (p = 0.026). There was no statistically significant difference between the two methods in terms of oxygen saturation levels (p = 0.27). However, the mean pulse rates recorded during the alginate impressions were significantly higher than those recorded during the digital impressions (p = 0.001).

Conclusion: The digital impression method may be preferred over alginate impressions to enhance treatment adherence in children by offering a more patient-friendly approach.

Purpose: This study aimed to evaluate the effects of artificial aging on the surface properties of CAD/CAM restorative materials by assessing changes in translucency, gloss, and surface roughness.

Materials and methods: Three CAD/CAM materials were tested: Cerasmart, Vita Enamic, and Initial LRF. Specimens were prepared and polished using three different finishing and polishing systems: Optiglaze Color, OptraFine Polishing System, and Vita Enamic Polishing Set Clinical. Surface roughness was measured using a non-contact laser profilometer. Translucency was evaluated with a UV-Vis spectrophotometer, and gloss was determined using a glossmeter. The specimens were stored in 0.02-N citric acid solution for seven days and subjected to a toothbrush abrasion procedure. All surface parameter measurements were repeated after aging.

Results: Before aging, the OptraFine Polishing System provided the smoothest surfaces for Cerasmart and Vita Enamic, while Optiglaze Color resulted in the smoothest surfaces for Initial LRF. After aging, a significant decrease in light transmittance was observed in all materials regardless of the finishing and polishing method used (p<0.014 for Cerasmart, p = 0.001 for Vita Enamic/Initial LRF before aging; p<0.001 for Cerasmart/Vita Enamic, p = 0.003 for Initial LRF after aging). Statistically significant differences in surface roughness (Ra, Rz, and Sa values) were found among the polishing methods for all materials (p<0.001). Optiglaze Color consistently resulted in the highest gloss values across all materials.

Conclusion: Aging had a significant impact on the surface properties of CAD/CAM materials, with variations depending on the material type and polishing system used. Light transmission decreased significantly in all materials after aging. The choice of finishing and polishing technique plays a critical role in maintaining the aesthetic properties of CAD/CAM materials over time.
