    Efficacy of laser-activated irrigation with the SWEEPS modality in removing calcium hydroxide from simulated internal resorption cavities
    (2023) Erkan, Erhan; Aydın, Rabia Nur; Falakaoğlu, Seda; Yeniçeri Özata, Merve; Gündoğar, Mustafa
    Aim: To compare the efficacy of shockwave-enhanced emission photoacoustic streaming (SWEEPS), sonic activation with EDDY, and passive ultrasonic irrigation (PUI) in the removal of calcium hydroxide medicaments from artificial internal resorption cavities. Methodology: Ninety mandibular premolars with single oval canals were prepared to size 50/0.04 and split longitudinally. Standardized cavities were prepared in the apical third of the root canal and filled with calcium hydroxide. The root halves were reassembled and divided into three groups (n = 30) according to the removal methods used. The amount of residual calcium hydroxide was evaluated using a four-grade scoring system. The differences between the groups were analyzed using the Kruskal–Wallis H test (p < 0.05). Results: SWEEPS removed significantly more calcium hydroxide than PUI (p < 0.003) and EDDY (p < 0.035). There was no significant difference between the EDDY and PUI groups (p = 1.000). Conclusion: None of the systems tested were able to completely remove the calcium hydroxide paste from the simulated internal resorption cavities; however, SWEEPS removed more calcium hydroxide than the EDDY and PUI techniques.

    Influence of access cavity design on calcium hydroxide removal using different cleaning protocols: a confocal laser scanning microscopy study
    (Korean Academy of Conservative Dentistry, 2023) Falakaloğlu, Seda; Özata, Merve Yeniçeri; Güneş, Betül; Silva, Emmanuel João Nogueira Leal; Gündoğar, Mustafa; Topal, Burcu Güçyetmez
    Objectives: The purpose of this study was to evaluate the influence of endodontic access cavities design on the removal of calcium hydroxide medication of the apical third of mandibular incisor root canal walls and dentinal tubules with different cleaning protocols: EDDY sonic activation, Er,Cr:YSGG laser-activated irrigation, or conventional irrigation with IrriFlex. Materials and Methods: Seventy-eight extracted human mandibular incisors were assigned to 6 experimental groups (n = 13) according to the endodontic access cavity and cleaning protocol for calcium hydroxide removal: traditional access cavity (TradAC)/EDDY; ultraconservative access cavity performed in the incisal edge (UltraAC.Inc)/EDDY; TradAC/Er,Cr:YSGG; UltraAC. Inc/Er,Cr:YSGG; TradAC/IrriFlex; or UltraAC.Inc/IrriFlex. Confocal laser scanning microscopy images were used to measure the non-penetration percentage, maximum residual calcium hydroxide penetration depth, and penetration area at 2 and 4 mm from the apex. Data were statistically analyzed using Shapiro-Wilk and WRS2 package for 2-way comparison of non-normally distributed parameters (depth of penetration, area of penetration, and percentage of non-penetration) according to cavity and cleaning protocol with the significance level set at 5%. Results: The effect of cavity and cleaning protocol interactions on penetration depth, penetration area and non-penetration percentage was not found statistically significant at 2 and 4 mm levels (p > 0.05). Conclusions: The present study demonstrated that TradAC or UltraAC.Inc preparations with different cleaning protocols in extracted mandibular incisors did not influence the remaining calcium hydroxide at 2 and 4 mm from the apex.

    Rubber Dam and Application Methods in Dental Practice
    (Selcuk University, 2021) Eskibağlar, Mehmet; Eskibağlar, Büşra Karaağaç; Gündoğar, Mustafa; Özyürek, Taha
    Isolation is necessary in most dental practices. Rubber dam method is often preferred for this process. Rubber dam improves the success of the process by providing proper isolation of the study area. In addition, it reduces aerosol formation. Today, it protects of the operator and protects the dental staff and the patients from infectious diseases such as coronavirus transmitted by droplets. By optimizing the way it works, it prevents possible soft mouth tissue injuries that you choose from the operator’s view. In this review article, rubber dam isolation method which is used frequently in dentistry is explained.
