ABSTRACTBackground: Broken instruments affect the outcome and prognosis. A broken instrument will prevent the procedure of cleaning and shaping, irrigation and obturation of the root canal on the obstructed root section causing failure in endodontic treatment. There are some treatments for broken instrument including retrieving a broken fragment file and bypassing it on the root canal. the aim of the case report aims to provide an alternative for retrieving broken instruments using the H-file braiding technique. Method: A 38-year-old female patient came to the Dental Conservation Clinic RSGM Prof. Soedomo FKG UGM. A patient got a history of initial root canal treatment in a clinic, which ended with a separated file on canine teeth left upper. No complain pain, from the investigation radiographic there is an instrument broken in half apical. The teeth 23 seen temporary restoration cavity class I is still in good. Retrieving broken instruments using the H-file braiding technique, preparation with step back techniques, obturation with warm vertical condensation technique and class I composite resin restorations with fiber-reinforced retention. Result: No complain pain after 2 weeks retrieving broken instrument.Conclusion: The technique of the H-file braiding technique is one technique to retrieve a broken instrument, this procedure is simple, cost-effective, harmless to the teeth and gives root canal sealing.

Background: Reactive Oxygen Species (ROS) released from hydrogen peroxide causes inflammation of the pulp. Remineralization action by fluoride-containing desensitizing agent (Casein Phosphopeptides-Amorphous Calcium Fluoride Phosphate/CPP-ACFP) occluding dentinal tubule, thereby minimizing the penetration of hydrogen peroxide into the pulp and affect the number of fibroblasts. The aim of this study was to determine the effect of fluoride-containing desensitizing agent (CPP-ACFP) application: before, after, and before-after in-office bleaching techniques using 40% hydrogen peroxide on the number of fibroblasts.Method: Twenty-eight maxillary molar teeth were divided into 4 groups, Control Group (bleaching treatment), Group I (CPP-ACFP application before bleaching), Group II (CPP-ACFP application after bleaching), and Group III (CPP-ACFP application before and after bleaching). Rats were sacrificed 5 days after and histological preparations were stained with HE. Fibroblasts counting was performed using a 1000x magnification light microscope.Result: ANOVA test showed that there were significant mean differences in the number of fibroblasts among the groups. The LSD test showed that there were statistically significant differences in almost all of the compared groups except between the Control Group and Group II.Conclusion: The number of fibroblasts in the pulp of rats applied CPP-ACFP before and after in-office bleaching was less than applied CPP-ACFP before or after in-office bleaching.

PENGARUH LAMA PEMANASAN DAN JENIS PREHEATED RESIN KOMPOSIT SEBAGAI BAHAN SEMENTASI TERHADAP KEKUATAN GESER PELEKATAN VINIR LITHIUM DISILICATE Mayasari, Rena; Untara, Tri Endra; Kristanti, Yulita

Pendahuluan: Vinir Lithium disilicate banyak diminati sebagai kebutuhan estetik gigi anterior. Pemilihan bahan sementasi penting diperhatikan untuk mencapai keberhasilan vinir. Pemanasan resin komposit untuk meningkatkan sifat fisik dan mekaniknya menjadikan preheated resin komposit sebagai alternatif semen resin yang banyak digunakan. Penelitian ini bertujuan untuk mengetahui pengaruh jenis resin komposit dan lama pemanasan preheated resin komposit sebagai bahan sementasi vinir lithium disilicate. Metode: Penelitian eksperimental laboratoris menggunakan 48 sampel gigi premolar maksila yang dibagi menjadi enam kelompok yaitu jenis resin komposit microhybrid dengan lama pemanasan 10, 20, dan 30 menit dan resin komposit nanohybrid dengan lama pemanasan 10, 20, dan 30 menit yang dipanaskan pada suhu 55ºC sebagai bahan sementasi lithium disilicate. Sampel disimpan dalam inkubator suhu 37º selama 24 jam, lalu diuji kekuatan geser pelekatan menggunakan Universal Testing Machine (UTM) kecepatan 0,5 mm/menit. Pengamatan tambahan dilakukan dengan mikroskop stereo untuk mengidentifikasi tipe kegagalan pelekatan. Hasil: Uji ANAVA dua jalur menunjukkan bahwa jenis preheated resin komposit memiliki nilai p=0,001 (p<0,05) artinya terdapat pengaruh signifikan jenis resin komposit nanohybrid dan microhybrid terhadap kekuatan geser pelekatan, sedangkan variabel lama pemanasan diperoleh nilai p=0,058 (p>0,05) artinya tidak ada pengaruh antar kelompok lama pemanasan resin komposit nanohybrid dan microhybrid terhadap kekuatan geser pelekatan. Simpulan: preheated resin komposit microhybrid sebahai bahan sementasi lithium disilicate menghasilkan kekuatan geser lebih baik dibandingkan nanohybrid. Lama pemanasan resin komposit suhu 55° selama 10, 20, dan, 30 menit tidak berpengaruh signifikan terhadap kekuatan geser pelekatan.
