{"title":"Effect of mixing tip design on the mechanical properties, porosity, and waste reduction of extra-light-body polyvinyl siloxane impression material.","authors":"Kaisha T Calvin, Eric Hu, Robert Masterson","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The purpose of this study was to compare the tensile strength, modulus of elasticity, porosity, and waste reduction of extra-light-body polyvinyl siloxane (PVS) impression material mixed with a helical impression tip or a new cartridge integrated system (NCIS) from the same manufacturer (Dentsply Sirona). The legacy teal tip (TT group) was compared with the NCIS red (RT group) and blue (BT group) mixing tips. Dumbbell-shaped specimens (TT, n = 17; RT, n = 15; and BT, n = 16) were prepared in accordance with German Institute for Standardization's rubber testing standard (DIN 53504.2017) and tested in a universal testing machine for tensile strength and modulus of elasticity. Porosity was evaluated via microcomputed tomography of cylindrical specimens (TT, n = 7; RT, n = 6; and BT, n = 7). Waste reduction was evaluated by comparing the mass of the mixing tips before use and after polymerization of the PVS to determine the difference in weight, which represented the amount of retained material (n = 11 per group). Tensile strength was analyzed using 1-way analysis of variance (ANOVA). Modulus of elasticity was analyzed using 1-way ANOVA with Tukey HSD. Porosity and waste reduction were analyzed using Shapiro-Wilk, Kruskal-Wallis, and Steel-Dwass tests. The analyses revealed no differences in tensile strength between groups (P = 0.493). The TT group had a significantly higher modulus of elasticity than the RT and BT groups (P < 0.001). The BT group had the highest mean porosity, and the difference between BT and RT was statistically significant (P = 0.048). The RT group showed the least material waste. Supporting the claims of the manufacturer, the NCIS tips generated tensile strengths comparable to that of the legacy tip and produced less waste, achieving waste reductions of 62% (RT) and 21% (BT) compared with the legacy tip. However, the RT and BT groups had a lower modulus of elasticity than the TT group, and porosity was increased in the BT group.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"73 3","pages":"28-33"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143966688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serologic test results were positive for anticentromere and antinuclear antibodies and negative for anti-topoisomerase I antibody, confirming the diagnosis of limited SSc. The oral manifestations were critical to the early diagnosis of limited SSc. Telangiectasia, labial fibrosis, and xerostomia were key indicators.

In this retrospective split-mouth study, 36 fluoride-containing sealants (Clinpro) and 36 ACP-containing sealants (Aegis) were evaluated 24 months after placement in the permanent first molars of 30 children aged 6 to 7 years. The sealants were inspected for retention based on the criteria of Oulis and Berdouses, with scores of 0, 1, and 2 representing total retention, partial loss, and total loss, respectively. In addition, the sealants were assigned scores for marginal integrity, marginal discoloration, and anatomical form based on the criteria of Feigal et al. Differences between groups in the occurrences of each evaluation variable were compared using relative risk with its 95% CI as well as the chi-square or Fisher exact test. The level of significance was set at P = 0.05. The retention success rates of the fluoride and ACP sealants after 24 months were 66.6% and 61.1%, respectively, but the difference was not statistically significant (P > 0.05). The overall clinical success of the fluoride-containing sealant was slightly greater than that of the ACP-containing sealant in terms of marginal discoloration and anatomical form; however, these differences were not statistically significant (P > 0.05). The marginal integrity of the sealant with ACP nanofillers was greater than that of the fluoride-containing sealant, but the difference did not reach statistical significance (P > 0.05).

This study aimed to investigate the antibacterial effect of 0.2% curcumin mouthwash on <i>Streptococcus mutans</i> in individuals undergoing fixed orthodontic treatment. For this double-blinded clinical study, 22 orthodontic patients aged 15 years or older with no systemic or periodontal diseases were selected and randomly divided into 2 groups of 11 individuals. One group received 0.2% curcumin mouthwash (intervention), while the other group received 0.2% chlorhexidine mouthwash (control) to use twice daily. Orthodontic elastics were collected from the patients' mouth immediately before the first use of the mouthwash, immediately after the first use, and after 20 days of mouthwash use. The elastics were stored in normal saline, and the samples were transferred to a microbiology laboratory for serial dilution, plating, and incubation. After 48 hours, the number of colony-forming units (CFUs) of <i>S mutans</i> were counted and compared. The Friedman and Wilcoxon tests were used for statistical analysis of intragroup data, while the Mann-Whitney U test was used for intergroup comparisons. A difference of P < 0.05 was considered statistically significant. Both the curcumin and chlorhexidine groups demonstrated a statistically significant decrease in CFUs of <i>S mutans</i> immediately after the initial use as well as after 20 days' use (P < 0.05). After the first use, there was no statistically significant difference between the groups in the reduction of CFUs (P = 0.071). However, after 20 consecutive days of mouthwash use, the curcumin group had a significantly greater decrease in CFUs of <i>S mutans</i> than the chlorhexidine group (P < 0.001). Both chlorhexidine and curcumin mouthwashes significantly reduced the number of <i>S mutans</i> colonies when used regularly. The results of the present study suggest that curcumin herbal mouthwash is a superior choice to chlorhexidine for orthodontic patients due to its long-term antibacterial properties.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"73 3","pages":"73-77"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
