Publisher : Faculty of Dentistry, Universitas Gadjah Mada

Selama prosedur preparasi saluran akar, kemungkinan patahnya instrumen selalu ada. Saat ini instrumen yang patah dapat dikeluarkan dengan menggunakan alat ultrasonik seperti jarum Miller yang dihubungkan dengan tip ultrasonik endo, selain itu diperlukan juga akses dan visibilitas yang baik sehingga memudahkan operator untuk mengeluarkan instrumen yang patah tersebut. Tujuan laporan kasus ini adalah untuk melaporkan keberhasilan pengambilan lentulo patah di dalam saluran akar menggunakan jarum miller yang dihubungkan dengan tip ultrasonik endo dikombinasikan dengan hedstroem no 25. Dalam makalah ini dilaporkan satu kasus perawatan saluran akar gigi molar satu kiri bawah pulpitis irreversibel pada pasien wanita 20 tahun, namun terjadi patah lentulo saat pengaplikasian bahan sterilisasi saluran akar. Pengambilan lentulo berhasil dilakukan pada kunjungan kedua dengan menggunakan jarum miller yang dihubungkan dengan tip ultrasonik endo serta hedstroem file no 25. Visibilitas didapatkan dengan melakukan coronal flaring menggunakan heroshaper dari mikro mega yang dihubungkan dengan alat rotary. Setelah 1 minggu, gigi diobturasi dengan teknik single cone pada saluran akar distal dan teknik kondensasi lateral pada saluran akar mesiobukal dan mesiolingual. Pada kunjungan berikutnya, gigi direstorasi dengan resin komposit disertai pasak dentatus screw. Setelah 2 bulan diamati secara radiografis dan klinis, tidak ada keluhan dari pasien.Broken Lentulo Removal During Root Canal Treatment On The First Molar Mandible Sinistra With Pulp Necrosis. During root canal preparation procedure, there is always potential for instrument breakage. Nowadays, broken instruments can be removed using ultrasonic instruments such as a needle miller connected to endo ultrasonic tip, but it needs good access and visibility in order to make it easier for the operator to remove the broken instruments. The aim of this case report is to present the successful removal of a broken lentulo left in a root canal by using smooth broach connected to a ultrasonic endo tip combined with an hedstroem file no 25. This paper reports a case of molar root canal treatment of the lower left irreversible pulpitis in 20 year-old female patient, but the incident of broken lentulo occured while applying root canal medicament. The effort to remove lentulo was successful on the second visits using a needle miller connected to endo ultrasonic tip and headstrom file no 25. Visibility was obtained by using a coronal flaring of micro mega hero shaper associated with the rotary tool. In the following week, the teeth was obturated with single cone technique on the distal root canal applying the lateral condensation technique on mesiolingual and mesiobuccal root canal. In the next visit, the teeth were restored with composite resin with dowel dentatus screw. After 2 months of being observed radiographically and clinically, there is no more complaint from the patient

Latar belakang. Trauma pada gigi dapat menyebabkan injuri pulpa dengan atau tanpa kerusakan mahkota atau akar. Pulpektomi menjadi pilihan perawatan pada fraktur mahkota yang membutuhkan restorasi kompleks. Gigi pasca perawatan saluran akar biasanya telah kehilangan struktur jaringan keras yang cukup banyak sehingga membutuhkan retensi intrakanal berupa pasak untuk mendukung restorasi akhir. Pasak Fiber Reinforced Composite (FRG) memiliki flexure dan fatigue strength yang lebih besar, modulus elastisitas yang mendekati dentin, kemampuan untuk membentuk monoblok (kompleks akar-pasak) dalam saluran akar, dan meningkatkan estetik jika dibandingkan dengan pasak logam. Resin komposit memiliki warna dan translusensi yang menyerupai dentin dan email sehingga mampu menghasilkan estetik yang baik pada gigi anterior. Tujuan. Melaporkan restorasi resin komposit dengan pasak FRG untuk memperbaiki gigi insisivus sentralis maksila yang mengalami fraktur mahkota kompleks pasca trauma. Kasus dan penanganan. Perempuan 20 tahun, gigi insisivus sentralis kanan dan kiri maksila mengalami Fraktur Ellis klas III akibat kecelakaan. Gigi 11 pulpitis ireversibel dan gigi 21 nekrosis pulpa. Kedua gigi malposisi. Dilakukan pulpektomi atau perawatan saluran akar multi kunjungan. Resin komposit dengan pasak FRG customized digunakan sebagai restorasi akhir. Kesimpulan. Restorasi resin komposit dengan pasak FRG customized memberikan hasil yang memuaskan secara estetik dan fungsional untuk merestorasi gigi insisivus sentralis pasca trauma dan perawatan saluran akar.

Post bleaching procedures often have free radicals trapped in dentin tubule and interprismatic enamel, leading to demineralization and denaturation. Sodium ascorbate is an antioxidant substance known to bind residual free radicals to stop demineralization and denaturation. The purpose of the study was to assess the calcium and phosphorus loss from the dentin surface following bleaching by 35% hydrogen peroxide and reversal by 35% sodium ascorbate andthe surface structure of the dentin. Six sound premolars were divided into their crown and root sections, with the crown subsequently being cut into four equal parts to obtain 24 samples. The calcium and phosphorus contents as well as the surface structure of the dentin were assessed using SEM-EDX. These were then divided into four groups, each containing six samples. Group A (control): the samples were bleached by 35% hydrogen peroxide, immersed in an artificial saliva, stored in an incubator at 37 °C for seven days. Group B: the samples were bleached by 35% hydrogen peroxide followed by the application of 35% sodium ascorbate for 5 minutes (once). Group C: the samples were bleached by 35% hydrogen peroxide followed by the applications of 35% sodium ascorbate (twice). Group D: the samples were bleached by 35% hydrogen peroxide followed by the applications of 35% sodium ascorbate (threetimes). The calcium and phosphorus contents as well as the surface structure of the dentin were re-assessed using SEM-EDX at the same locations. The results of one-way ANOVA indicated a difference in the calcium loss in the four treatment groups (p<0.05), but there was no difference in the phosphorus loss. An LSD test showed that there was a difference in the calcium loss between group A and groups C and D or between group B and groups C and D. The dentin tubules in group A were larger than group B, C and D. The frequency of 35% sodium ascorbate application had an effect on the calcium loss and the surface structure in the dentin bleached by 35% hydrogen peroxide.

Background: Restoration of the teeth immediately after bleaching with 35% hydrogen peroxide (H2O2) is contraindicated due to the remnant of free radicals that will stay inside enamel and dentin for 1-3 weeks and reduce the adhesion of composite resin. Sodium ascorbate is an antioxidant substance known to bind free radical residues, thereby shortening the delay in restoration. Purpose: The purpose of this study was to examine the resin bond strength of bleached dentin influenced by the application of 35% sodium ascorbate. Methods: Nine premolars were divided into their crown and root sections, with the crown subsequently being cut into four equal parts to obtain 36 samples. These were then divided into four groups, each containing nine samples. Group A (control): samples were bleached using35% hydrogen peroxide, immersed in an artificial saliva, stored in an incubator at 37°C for seven days and then filled with a composite resin. Group B:samples were also bleached by means of 35% H2O2 followed by one application of 0.025 ml 35% sodium ascorbate for 5 minutes and restored with composite resin. Group C: samples were bleached with 35% H2O2, followed by two applications of 0.025 ml 35% sodium ascorbate for 5 minutes, and restored with a composite resin. Group D: dentin was bleached with 35% H2O2 followed by three applications of 0.025 ml sodium ascorbate 35% for 5 minutes and restored with a composite resin. The shear bond strength of the composite resin was measured by a universal testing instrument (Zwick, USA). Data was analyzed by means of one-way Anova and LSD. Results: The highest mean shear bond strength of composite resin was in group C, while the lowest was in group B. The result of one-way Anova indicated a difference in the shear bond strength of composite resin in the four treatment groups (p < 0.05). An LSD test showed there to be a difference in shear bond strength of composite resin between group A and groups C and D or between group B and groups C and D. There was no difference in shear bond strength of composite resin between group A and group B or between group C and group D. Conclusion: Application frequency of 35% sodium ascorbate affect on shear bond strength of composite resin restoration in bleached dentin by 35% H2O2.

Sealer is one of root canal filler materials which has been developed and has an antibacterial agent to keep root canal sterile during and after an obturation process. This study aimed to find out the effect of sisal nanofiber addition to resin epoxy-based sealer on the antibacterial power against Enterococccus faecalis (E. faecalis) which is known as adaptive and potent bacteria which can be both aerobic and anaerobic. Sisal fibers were processed through many stages to make it nano sized (scouring, bleaching, neutralization, ultrasonification, and freeze-drying). Once nano-sized sisal fibers had been obtained, they were then mixed with sealer powder (AH26) in different concentrations: powder 0%, 0.25%, 0.5%, 0.75% and 1%. These concentrations were chosen based on preliminary research for reasonable contact angle measurement of sisal-sealer mixture. Antibacterial effect was examined using the diffusion method, each concentration was tested in 5 petri dishes which were planted with 1.5 X 108 CFU/ml E.faecalis bacteria. Each dish consisted of 5 holes (6 mm in diameter), each hole represented each concentration of nano sisal and sealer which were mixed until homogenous for 3 minutes before added to each hole. The dishes were then incubated for 48 hours at 37 °C. Inhibitory zones were measured, and analyzed using one-way ANOVA. The one-way ANOVA result showed that p=0.502 (p>0.05), meaning that the sisal nanofiber addition to epoxy resin-based sealer had no effect on E.faecalis inhibition. Thus, there was no effect of sisal nanofiber addition to epoxy resin-based sealer on E. faecalis.

Dental trauma mostly damages the maxillary anterior teeth, affecting the individual’s esthetics, functionality, and psychological well-being. Restorative dentistry treatment is required to obtain a natural appearance based on the smile design approach. The aim of this report is to characterize the procedure of complicated cosmetic restoration of the six maxillary anterior teeth, which results in straighter and more beautiful natural-looking smiles. A 32-year-old male patient presented with multiple crown fractures in the anterior maxillary teeth, resulting in an unaesthetics smile. The patient also had a deep bite. A comprehensive aesthetics dental treatment was carried out. The dental treatment plan had to be carefully executed by considering several factors such as dental convexities and contours, re‑establishment of function, and esthetics. Smile design should always be approached as a multi-factor decision-making, which enables the doctor to treat patients using a personalized and interdisciplinary approach.

The geometric design of an endodontic file includes cross-sectional shape, taper, and pitch. NiTi endodontic files of OneCurve (MicroMega) are made of two variations of cross-sectional shape, that is, double-s shaped and triple helix. Various kinds of modifications were made to increase the resistance of the NiTi endodontic files from fracture. Cyclic fatigue is the most common factor that causes a fracture of the endodontic file. Objective: The purpose of this study was to obtain a NiTi endodontic file design that has the best cyclic resistance value based on its taper size and number of pitch. Methods: This study used OneCurve endodontic file size 25.06, then scanned with MicroCT Scan and modified the geometric design. The number of file modifications was nine. Taper size modifications were 4%, 6%, and 8%; the number of pitch modifications was reduced by three, fixed, and added by three. Cyclic fatigue measurement simulations were carried out using the finite element method three times each. The result data were analyzed using a two-way ANOVA test and then continued with LSD. Results: The results of the statistical test showed that there was an effect of the size of the taper on the cyclic fatigue values. Endodontic files with a size of a taper 4% had the lowest cyclic fatigue value. Conclusion: The conclusion of this research was that the taper size affects the value of cyclic fatigue in continuous endodontic files made of nickel-titanium with variable cross sections. The number of pitch did not show a significant effect on the cyclic value.
