Background: Intracanal medicaments Ca(OH)₂ must have the ability to contact directly with bacteria adhering to the dentinal tubules. However, the narrow and complex shape of the root canal makes it difficult for Ca(OH)2 to penetrate the root canal apically. This research aimed to assess the flowability of nanoparticle Ca(OH)₂ Palimanan by quantifying the penetration of the coronal, middle, and apical thirds of the root canal.Methods: This research comprised two distinct groups: one group included nanoparticles of Ca(OH)₂ Palimanan, while the other consisted of conventional Ca(OH)₂. The paste was then applied to standardized root canals (n=3 per group) with 5 times measurements for each sample. All samples were then incubated at 37oC, 100% humidity. The flowability of the root canals was measured using scanning electron microscopy (SEM) on day 14. The data was analyzed using ANOVA and a post-hoc t-test, with a significance level of p<0.05.Results: The use of Ca(OH)₂ Palimanan has been found to be more effective in reaching deeper into the dentinal tubules of the root canal, particularly in the coronal, middle, and apical areas, compared to traditional Ca(OH)₂. This occurs because the particle size of Ca(OH)₂ Palimanan is smaller with a more rounded shape than conventional Ca(OH)₂ so that it to flow into narrow and complex areas, especially in the apical root canals.Conclusion: Nanoparticle Ca(OH)₂ Palimanan flow deeper than conventional Ca(OH)₂

Introduction: Gypsum, Portland, and apatite cement, and gypsum have been developed as dental materials for a long time. Similarity of the three materials leads to some relevant approaches to improve the characteristic of dental materials. Water reducing agent is commonly used in detergent or soap and also used as a conventional method in the cement industry to increase the handling and mechanical property. Cement paste mixed with water reducing agent is more flowable (ease handling), and the set mass is harder (mechanical property increased). However, it has a problem with biomaterial cement due to the biocompatibility. This water reducing agent is harmful to living tissue. Therefore, a new approach will be demonstrated in this research. Methods: In this study, the hydrophilicity of cement powder was modified by ozone gas treatment. Ozone gas treatment will be applied to modify the hydrophilicity of cement particles; therefore, it can act similar to the water reducing agent. Results: The hydrophilicity of gypsum, Portland, and apatite cement powder was significantly increased after ozone gas treatment. The hydrophilicity improvement of cement powder increased the ability of water to interact with the cement powder. The benefit is the flowability improvement of cement paste. Therefore, the manipulation index would also be increased. The mechanical property would be increased because the water added for manipulation was decreasing. Conclusion: Ozone gas treatment could improve the hydrophilicity of gypsum, Portland, and apatite cement powder.Keywords: Gypsum, Portland, apatite cement, hydrophilic, ozone

Semen apatit dapat menjadi alternatif bahan pengganti jaringan tulang karena memiliki sifat osteokonduktif, biokompatibel, mudah diserap oleh tubuh, self-setting, dan dapat digunakan sebagai bahan pembawa obat. Sirih cina (Peperomia pellucida (L). Kunth (P. pellucida) secara empirik telah dimanfaatkan sebagai obat tradisional dan secara ilmiah juga diketahui memiliki kemampuan farmakologis untuk membantu penyembuhan tulang dan luka. Penambahan ekstrak P. pellucida ke dalam semen apatit diharapkan dapat meningkatkan pembentukan tulang baru. Penelitian ini merupakan penelitian awal dengan mempelajari efek penambahan ekstrak pada setting time semen apatit. Penelitian menggunakan metode eksperimental laboratorik dan menggunakan analisis data One Way Anova dilanjut dengan uji Posthoc yaitu uji Least Significant Differences (LSD). Sampel terdiri dari 5 kelompok, yaitu kelompok kontrol, kelompok dengan penambahan 10% dan 20% pada formulasi bubuk, dan kelompok dengan penambahan 10% dan 20 pada formulasi larutan. Hasil penelitian menunjukkan bahwa pada rasio L/P 0,3 dan 0,4 setting time tercepat terdapat pada kelompok dengan penambahan 20% ekstrak pada formulasi bubuk pada rasio 0,3. Setting time pada kelompok dengan penambahan 10% ekstrak pada formulasi larutan dengan rasio 0,4 juga mengeras lebih cepat daripada kelompok kontrol tapi tidak signifikan. Kesimpulan penelitian ini adalah bahwa penambahan ekstrak P. pellucida pada formulasi bubuk maupun larutan dapat memengaruhi setting time sehingga semen mengeras lebih cepat.
