"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 57-61The aim of the present study was to assess the response of rat dental pulp to direct pulp capping with ethanol extracts of propolis (EEP). An occlusal cavity was prepared on the right maxillary first molar of Spraque-Dawley rats. The dental pulp was exposed and then lined with a zinc oxide-based filler as a control (group I), or with EEP (group II). Then, each cavity was filled with glass ionomer cement. The animals were sacrificed at week l, 2, or 4. Biopsy samples were obtained, and these were stained and viewed by a light microscopic. The histological examination was based on the presence of polymorph nuclear leukocytes and macrophages, and also the dentinal bridge formation. Data were statistically analyzed by using Kruskall-Wallis and Mann-Whitney tests. The results showed that the inflammatory response of EEP group was relatively milder compared to the control group, but there was no significant difference (p>0.05) between the two groups. There was no dentinal bridge formation seen in both groups. Therefore, the present results suggest that direct pulp capping with EEP in rats may delay dental pulp inflammatory process and fail to stimulate reparative dentin."

"Latar Belakang: Karies gigi merupakan masalah kesehatan yang dialami setengah populasi penduduk dunia (3,58 milyar jiwa) dan penyakit gigi dengan prevalensi terbesar di Indonesia. Insidensi karies mencapai pulpa juga selalu meningkat setiap tahunnya. Perawatan saluran akar merupakan tindakan kuratif yang dilakukan untuk mengatasi hal tersebut. Menurut studi di berbagai negara, tingkat kegagalan PSA dapat mencapai 30% dengan melibatkan banyak faktor. Saat terjadi kegagalan, tindakan yang paling diutamakan untuk dilakukan adalah perawatan saluran akar ulang untuk mempertahankan gigi asli dari pasien. Oleh karena itu, perlu dilakukan penelitian mengenai prevalensi PSA ulang di RSKGM FKG UI dengan mengidentifikasi dan mengevaluasi penyebab kegagalan PSA dan faktor-faktor yang mempengaruhi hal tersebut untuk mencegah hal tersebut terjadi lagi di masa yang akan datang. Tujuan: Mengetahui prevalensi perawatan saluran akar ulang di Rumah Sakit Khusus Gigi dan Mulut Fakultas Kedokteran Gigi Universitas Indonesia periode 2019-2021.

"The primary tooth with caries process could be abscess and became non-vital inflammation of the pulp tissue extents into the root canals. An effort to maintain the non-vital primary teeth with fistula ispulpectomy. The primary tooth pulpectomy is a common clinical procedure. The choice of filling material and antibacterial properties against organism to inhabit infected primary root canal is important. The choice of filling material is zinc oxide eugenol and antibacterial medicament is formocresol. One appointment formocresol pulpectomy procedure is indicated when inflammation of the pulp tissueextend into the root canals, and possibly involves the periapical and/or bifurcation area. ln this case, after treatment with one-appointment formocresol pulpectomy in non-vital incisive lateral primary tooth withfistula is successful in one and eight months. This procedure provides an alternative to extraction and space maintenance when the pediatric dentist encounters a non-vital primary tooth."
