Background: Propolis is a natural resinous substance collected by honeybees, chiefly from buds and the leaves, branches, and bark of trees. Its role as a wound-healing gel has been studied, but the use of a propolis hydrogel in the treatment of dentinal hypersensitivity has not been evaluated. Dentin hypersensitivity (DH) is commonly treated via iontophoresis using fluoridated desensitizers. The aim of the present study was to compare and evaluate the effects of a 10% propolis hydrogel, 2% sodium fluoride (NaF), and 1.23% acidulated phosphate fluoride (APF) when used in conjunction with iontophoresis for the treatment of cervical dentin hypersensitivity (DH). Methods: Systemically healthy patients complaining of DH were selected for this single-centre, parallel, double-blind randomized clinical trial. Three substances were selected as desensitizers for study in the present trial: a 10% propolis hydrogel, 2% sodium fluoride, and 1.23% acidulated phosphate fluoride, all in conjunction with iontophoresis. Any decrease in DH following the application of specific stimuli was assessed at baseline, before and after application, on the 14th day following use, and on the 28th day following the intervention. Results: Intra-group comparisons show diminished values of DH at maximum post-op follow-up intervals which were significantly trimmed down from the baseline (p < 0.05). The 2% NaF demonstrated a significant reduction in DH over 1.23% APF and the 10% propolis hydrogel (p < 0.05). However, there was no statistically significant difference in the mean difference between the APF and propolis hydrogel groups assessed via tactile, cold, and air tests (p > 0.05). Conclusion: All three desensitizers have proved to be useful when used in conjugation with iontophoresis. Within the limitations of this study, a 10% propolis hydrogel can be used as a naturally occurring alternative to commercially available fluoridated desensitizers.

In Saudi Arabia, the prevalence of diabetes mellitus (DM) is high. DM is a risk factor for periodontal disease. The current study aimed to estimate the prevalence and potential associated factors for periodontitis among type I and II DM patients in Abha, Saudi Arabia. A cross-sectional study was conducted among patients with DM who attended the Periodontal Consultant Center at King Khalid University and Aseer Central Hospital, in Abha city, from January 2020 to January 2022. A questionnaire was used to collect relevant data. Patients were assessed for the severity of periodontitis. A total of 499 DM patients were enrolled in this study. The prevalence of periodontitis was 7.4% among type I DM and 46.4% among type II DM patients. The prevalence of periodontitis was significantly associated with age among type I DM patients (p-value = 0.001) and type II DM patients (p-value = 0.001), respectively, and smoking among type I DM patients (p-value = 0.002) and among type II DM patients (p-value = 0.000), respectively. Age and smoking were the potential associated factors for the prevalence of periodontitis among type I and II DM. The study provides evidence about the prevalence of periodontitis among DM patients, creates awareness regarding the factors that potentially contribute to worsening periodontal tissues, and the importance of early diagnosis and prevention to avoid the irreversible destruction of the periodontal tissues.

Background: Regularly removing dental plaque is key to good oral hygiene and gingival health promotion. This study aimed to compare the effects of using soft and medium toothbrushes using the plaque index (PI), gingival index (GI), and bleeding on probing (BOP) index. Material/methods: A randomized parallel-group study design was used. Sixty-four participants were randomly assigned to 2 similar intervention groups (medium and soft toothbrush groups). The PI, GI, and BOP indexes were used. The median and median difference of PI, GI, and BOP were calculated. SPSS was used for data entry and analysis. Wilcoxon and Mann-Whitney U tests were used for data analysis. Results: The median scores of GI, PI, and BOP significantly decreased from 1.8, 1.7, and 2.0, respectively, before using medium toothbrushes to 0.0, 0.1, and 0.0, respectively, after using medium toothbrushes (all P<0.0001). Similarly, the median scores of GI, PI, and BOP significantly decreased from 2.0, 1.7, and 2.0, respectively, before using soft toothbrushes to 1.1, 0.9, and 1.0, respectively, after using soft toothbrushes (P<0.0001). The median differences in GI, PI, and BOP scores among those using medium toothbrushes were higher than the median differences among those using soft toothbrushes [(1.8 vs 0.9), (1.6 vs 0.8), and (2.0 vs 1.0), respectively]. These differences were statistically significant (P<0.0001). Conclusions: This study concludes that medium and soft toothbrushes were effective in removing plaque and controlling gingivitis. Medium toothbrushes were more effective than soft toothbrushes in achieving these outcomes.

To assess knowledge, attitudes, and practices (KAP) regarding maternal periodontal health, its impact on pregnancy outcomes, and preventive oral care among dentists, gynecologists, and pregnant women in Southwestern Saudi Arabia. A cross-sectional survey was conducted among 499 participants. Knowledge, attitudes, and practices were assessed using group-specific items: Knowledge (awareness of periodontal disease, effects on pregnancy, and training/literature), attitudes (importance of maternal oral health and interest in further education), and practices (oral hygiene, dental visits, and provider counseling). Mean scores were calculated for each group, divided by the maximum attainable score, converted to percentages, and categorized as good (≥75%), moderate (50-74%), or poor (<50%). Categorical differences were analyzed using Chi-square tests with Bonferroni-adjusted post-hoc comparisons (p < 0.05). Dentists and pregnant women had higher knowledge scores (56.2 and 55.6%) than gynecologists (33.0%). Good knowledge was most frequent among dentists (44.0%) vs women (10.3%) and gynecologists (10.2%) (p < 0.001); poor knowledge predominated among gynecologists (67.3%). Practices were highest among dentists (67.5%), followed by women (50.8%) and gynecologists (47.6%), with poor practice most common among gynecologists (65.3%) and good practice most frequent among women (62.3%) (p < 0.001). Attitudes were highest among dentists (81.7%), followed by gynecologists (72.7%) and women (71.0%), with positive attitudes predominating across all groups. Dentists had the highest knowledge, gynecologists the lowest knowledge and practices, and pregnant women the strongest preventive behaviors. Enhancing gynecologists' knowledge of the oral-systemic link and reinforcing preventive oral care among pregnant women can support early detection of periodontal disease and reduce adverse pregnancy outcomes, including preterm birth and low birth weight.

Aim: This study evaluated the effect of manual and electronic toothbrushes on the color stability (∆E*) and surface roughness (Ra) of four CAD/CAM ceramics after their immersion in coffee for 2 and 4 weeks. Methodology: A total of 160 specimens (Vitablocs Mark II, Ceramill Zolid zirconia, Vita Triluxe Forte, and IPS e.max CAD) were divided into four brushing subgroups (manual, sonic, oscillating–rotating, and ionic). The samples underwent daily coffee staining, thermocycling (5–55 °C), and twice-daily brushing. Color parameters (L, a, and b) were assessed and measured utilizing a spectrophotometer (Vita Easyshade) at baseline, 2 weeks, and 4 weeks. ∆E* was calculated using the CIEDE2000 formula, and surface roughness (Ra, µm) was assessed via contact profilometry at the study’s conclusion. Data were analyzed using Kruskal–Wallis and Mann–Whitney tests (α = 0.05). Results: Among the tested samples, IPS e.max ceramic with manual toothbrushing exhibited the highest ΔE* values after 2 and 4 weeks (∆E* = 4.424 and ∆E* = 4.802) of immersion. Moreover, Ceramill Zolid zirconia demonstrated the highest ΔE* values with ionic brushing (∆E* = 4.883 at 2 weeks; ΔE* = 4.760 at 4 weeks). Significant differences were observed among ceramics and cleaning methods, with manual/ionic brushing causing the greatest changes (p < 0.05). IPS e.max had the highest Ra with manual brushing (0.745–0.789 µm), whereas Ceramill Zolid zirconia with ionic brushing showed the highest Ra values among the electric methods (0.745–0.757 µm). Conclusions: Manual brushing induced clinically unacceptable color changes in IPS e.max CAD, whereas ionic brushing adversely affected Ceramill Zolid zirconia. All brushing methods increased surface roughness beyond acceptable limits.
