ABSTRACT Debonding between post and resin cement often occurs due to inadequate smear layer removal.Currently, the wide use of Chitosan as an alternative irrigating solution can remove the smear layer. This studyaimed to determine the effect of 0.2% chitosan high molecule nanoparticle (CHMN) on the push-out bond strength ofresin cement in post-restoration and types of adhesion failure using the different irrigating solutions. Endodontictreatment was performed on 24 mandibular premolars, which were divided into four groups, namely group 1: 0.2%CHMN, group 2: 2.5% sodium hypochlorite (NaOCl) and CHMN, group 3: 5.25% NaOCl and CHMN, group 4: 2.5%NaOCl and EDTA 17%. The final restoration was done using prefabricated glass fiber posts, and each sample wassliced into three segments transversally with a thickness of 2 mm. A push-out test was performed with a universaltesting machine, and failure modes were observed under a stereomicroscope. Data were analyzed with a one-wayanalysis of variance (ANOVA), LSD, and Kruskal-Wallis tests. The results showed a significant difference in pushoutbond strength of resin cement in post-restoration between all groups. The Kruskal-Wallis test showed nosignificant difference between types of adhesion failure. In conclusion, 0.2% CHMN affects the push-out bondstrength of resin cement in post-restoration regardless of or without a combination of NaOCl. However, there wereno effects on the types of adhesion failure. Keywords: bond strength, 0.2% chitosan solution, endodontic irrigation, fiber post

ABSTRACT Teeth after root canal treatment are at a higher risk of fracture than vital teeth. After root canaltreatment, the causes of tooth fracture are multifactorial, both iatrogenic and non iatrogenic. One of them isirrigants, although very useful for disinfection. Irrigants are known to change the chemical components andstructure of the root canal surface dentin by modifying the proportion of calcium and phosphate minerals. Thisresearch is an experimental laboratory study with a post-test-only group research design to analyze the effect ofirrigating solutions of nanohydroxyapatite, high molecular chitosan, NaOCl, and EDTA with their appropriatecombination for the test group on the fracture resistance of teeth after root canal treatment. Root canal treatment wasperformed on 24 mandibular premolars, with the group I; irrigating solution of nanohydroxyapatite, group II;irrigation of nanohydroxyapatite solution with the addition of 0.2% chitosan, group III; irrigation with 2.5% NaOClsolution and 0.2% chitosan solution, group IV; irrigation solution of 2.5% NaOCl and 17% EDTA. ANOVA testshowed a significant difference in fracture resistance (p0.05) between each group. The highest average fractureresistance was seen in group II, namely the irrigation group using a solution of nanohydroxyapatite with theaddition of 0.2% chitosan, which was 363.644 ± 10,896 N. fracture after root canal treatment.KEYWORDS: nanohydroxyapatite, irrigation solution, fracture resistance

Teeth physiologically undergo demineralization and remineralisation processes. One way to reduce demineralization can be done with the use of CPP-ACP (Casein Phosphopeptide-Amorphous Calcium Phosphate), which has high calcium bioavailability. The use of natural materials products in the field of dentistry is currently growing, one of which is bilimbi/ starfruit (belimbingwuluh) that is rich in minerals and has many benefits. This study aims to analyze the effect of extract of bilimbi in tooth enamel remineralisation which is tested by using SEM and EDX equipments so that the difference of enamel surface microstructure and the amount of calcium and phosphorus content of tooth enamel surface can be identified. A total of eight hidden molar teeth were extracted, cut into four parts and divided into four groups, namely group I: the teeth applied with the wuluh bilimbi gel, group II: the teeth applied with CPP-ACP gel, group III: the teeth applied with the combination gel of starfruit extract and CPP-ACP gel, group IV: without any application. The result of this study was assessed qualitatively and it was noticeable that the treatment group combination of CPP-ACP gel and starfruit gel had the smoothest enamel surface microstructure. Quantitatively, there were significant difference is the three treatment groups (pâ‰¤ 0.05). The conclusion of this research is the effect of the application of wuluh bilimbi extract gel, CPP-ACP gel and gel combination of starfruit with CPP-ACP gel towards the remineralisation and microstructure of tooth enamel surface.

The success of fixed restoration preparation relies on several factors i.e. preparation of abutment tooth which must consider pulp-dentin complex and degree of occlusal traumatism. The thinner remaining dentin thickness during abutment preparation, the easier for inflammation and microbial invasion to occur. Inflammation of the pulp with release of inflammatory mediators such as prostaglandin, interleukin and microbial invasion through dentinal tubules played an important role in bone resorption and periapical lesions. This article was aimed to find out the treatment for periapical abscess resulted from porcelain-fused-to-metal (PFM) fixed restoration on maxillary left canine. A 56 year-old male patient was referred to clinic at Department of Conservative Dentistry, Faculty of Dentistry University of Sumatera Utara. He had a bridge from 23 to 26 on his maxillary left side. He felt discomfort in his maxillary left canine. Radiographic evidence showed radiolucency at apical area and clinical evaluation revealed periapical abscess at gingival mucosa of the tooth. Patient felt tenderness to percussion and palpation. Sequence of the treatment procedures was undertaken as follows: trephination and abscess drainage, root canal treatment using step back technique, obturation using lateral condensation method and eventually restored with composite resin using silane as coupling agent. At two-month evaluations, patient had no dental complaint, no tenderness to percussion and palpation as well as absence of clinical and radiographic periapical abscess. As conclusion, root canal treatment following hermetic root canal obturation and proper final restoration for periapical abscess resulted from PFM fixed restoration will determine the success of the treatment outcome.

Penggunaan bahan adhesif pita serat penguat polietilen dengan resin komposit sebagai pasak buatan semakin banyak diminati. Pemasangan pasak ini tidak membutuhkan pelebaran saluran akar yang lebih banyak sehingga dapat mengurangi risiko terjadinya fraktur akar. Wetting resin dipakai sebagai wettability untuk meningkatkan perlekatan interfasial. Terkadang para klinisi sering menggunakan flowable resin sebagai penggantinya. Penelitian ini bertujuan untuk mengetahui ketahanan fraktur penggunaan pita serat penguat poli etilen anyaman braided dan locked-sticthed threads sebagai pasak buatan pada restorasi pasca perawatan endodonti dengan aplikasi wetting resin dan flowable resin. Empat puluh gigi premolar mandibular yang telah diekstraksi dan memiliki ukuran sama dibagi menjadi empat kelompok. Kelompok A (locked-sticthed+wetting resin), B (locked-sticthed+flowable resin), C (braided+wetting resin) dan D (braided+flowable resin). Setelah pemotongan mahkota dan perawatan endodonti dilakukan pemasangan pasak buatan. Pita dibenamkan ke dalam semen resin dual cured dan dilanjutkan dengan pembentukan mahkota dari resin komposit. Setelah thermocycling, dilakukan uji tekan searah aksial gigi dengan kecepatan 0,5mm/detik sampai terjadi fraktur menggunakan Universal Testing Machine. Nilai beban fraktur dan pola fraktur yang terjadidicatat. Hasil uji statistik Anova menunjukkan tidak terdapat perbedaan signifikan pada ketahanan fraktur pasak buatan pita serat penguat dengan pola anyaman dan wettability yang berbeda (p= 0,367). Dengan adanya keterbatasan penelitian ini, pola fraktur pasak fiber anyaman locked-sticthed threads dan braided dengan wetting resinmenunjukkan 80-90% mudah direstorasi kembali. Sebagai kesimpulan, penggunaan pita serat penguat polietilen sebagai pasak buatan dengan anyaman berbeda memiliki ketahanan fraktur yang sama. Akan tetapi, pola fraktur pada pasak yang menggunakan wetting resin lebih mudah direstorasi kembali dibandingkan dengan flowable resin.
