Abstract

Background: Pulp inflammation can be marked by the increase of prostaglandin E2(PGE2) level compared to normal pulp. The increase of PGE2 may lead to vasodilatation, increase of vascular permeability, pain and bone resorption. Watermelon frost has been well known in Chinese society for pain relief and inflammation in oral cavity and teeth. Purpose: The aim of this study was to investigate that watermelon frost can be used to decrease the PGE2 level. Method: 27 samples of pulp tissues used in this in-vitro study, were extirpated from the patients’ teeth with symptomatic irreversible pulpitis referred to clinic of Conservative Dentistry, RSPGM Faculty of Dentistry, USU. Trial materials were applied to 27 samples i.e. watermelon frost as a trial material and commercial watermelon frost and eugenol to observe their effect on PGE2. PGE2 level of each material was detected through ELISA method by measuring and comparing the absorbance reading of the wells of the samples against standards with a micro plate reader at W1 = 650 nm and W2 = 490 nm. Result: The result showed the biggest effect was found in the third group (eugenol), mean 4.6933, followed by the first group (watermelon frost as a trial material), mean 18,1578 then the second group (commercial watermelon frost), mean 82,2689. OneWay ANOVA revealed that there were significant differences among all trial materials (p < 0.001) on PGE2 level. Conclusion: This study demonstrated that watermelon frost can be used to decrease the PGE2 level in inflamed pulp tissue and led to the acceptance of traditional medicine and natural products as an alternative form of dental care.

Abstract

Gigi imatur dengan nekrosis pulpa akibat trauma , karies atau pathosis pulpa. Dimana pembentukan dentin terganggu dan perkembangan akar berhenti sehingga terjadi perubahan warna gigi. Mineral trioxide aggregate (MTA) adalah bahan alternatif yang dapat digunakan untuk apeksifikasi apeks terbuka karena biokompatibilitasnya, nonmutagenisitas, non-neurotoksisitas, kemampuan regeneratif, dan sifat seal yang baik. Pada kasus ini penggunaan MTA sebagai plug apikal, pada gigi yang imature dengan apeks terbuka merupakan keputusan yang tepat. Tujuan dari laporan kasus ini adalah menjelaskan penggunaan MTA sebagai apical pluq pada gigi insisivus lateral maksila dengan diagnosis pulpa nekrosis dengan apeks terbuka dan dilanjutkan bleaching internal. Seorang pasien pria 43 tahun yang datang ke RSGM, Universitas Sumatera Utara dengan keluhan utama gigi yang berubah warna . Pemeriksaan radiografi menunjukkan apeks terbuka untuk gigi #12. Setelah cleaning and shapping dilakukan, kalsium hidroksida ditempatkan sebagai medikamen intracanal. MTA diletakkan kedalam saluran akar dengan ketebalan 3-4 mm menggunakan hand pluggers. Obturasi dengan gutta-percha termoplastik. Penggunaan MTA telah banyak direkomendasikan untuk kasus apeks terbuka. Karena memiliki apical seal yang baik, biokompatibilitas dan kemampuan regenerasi jaringan periodontal. Setelah di Follow up tidak adanya keluhan baik secara klinis maupun radiografi. Laporan kasus ini menunjukkan MTA sebagai bahan alternatif untuk apical plug pada metode konvensional apeksifikasi.

Abstract

Various post and core materials have been developed for endodontic restorations. Polyether ether ketone (PEEK) has an elastic modulus similar to dentin, reducing stress and improving tooth biomechanics, which may lower the risk of complications in final restorations. The objective of this systematic review was to synthesize findings from studies comparing the fracture resistance and stress distribution of post and core systems made from polyether ether ketone (PEEK) with those constructed from conventional materials. The review, conducted following PRISMA 2020 guidelines, involved a search of multiple databases, including PubMed, ScienceDirect, Wiley Online Library, Semantic Scholar, and Google Scholar, for studies published between 2014 and 2024. Keywords such as polyether ether ketone, PEEK, post-core, and endodontically treated teeth were used, resulting in 788 articles, of which 13 met the eligibility criteria. The findings indicated that PEEK post and core systems exhibited lower stress concentrations compared to conventional materials, thereby reducing the risk of irreparable root fractures. PEEK shows great potential as a material for post and core restorations. However, its use in endodontically treated teeth is not well-explored, and further research is required to better understand its mechanical properties in this context.
