Abstract

ABSTRACTIntroduction: Root canal treatment (RCT) of mandibular third molars is often considered challenging due to anatomical variability, limited accessibility, and difficulty achieving proper isolation. As a result, extraction is frequently chosen. This case report outlines a successful single-visit RCT on a right mandibular third molar with a curved canal and Class II disto-occlusal caries. Case Report: A 30-year-old female presented with a large cavity on her right lower molar and requested a restorative treatment. Three weeks earlier, devitalization and temporary restoration had been performed by another dentist. Clinical examination revealed no periapical lesion, and percussion testing was negative. Radiographic analysis showed a slight curvature in the distal canal. A pre-curved K-File and the One Curve System were used for instrumentation. The canal was obturated in a single visit, followed by restoration using direct composite and short fiber-reinforced composite. Matrix and PTFE tape were utilized for proper adaptation in the distal area. Conclusion: With accurate diagnosis, understanding of anatomical complexity, and appropriate technique, single-visit RCT on mandibular third molars is achievable. This case supports the viability of conservative treatment for necrotic third molars with asymptomatic apical periodontitis, avoiding unnecessary extraction.Keywords single visit, root canal treatment, third lower molar, curved canal, composite restoration. ABSTRAKPendahuluan: Perawatan saluran akar (RCT) pada molar ketiga mandibula menantang karena variasi konfigurasi saluran, kesulitan akses ke area posterior, dan tantangan dalam isolasi. Akibatnya, pencabutan sering menjadi pilihan. Laporan kasus ini mendeskripsikan protokol RCT kunjungan tunggal pada molar ketiga kanan mandibula dengan saluran melengkung dan karies disto-oklusal kelas II. Laporan Kasus: Seorang wanita 30 tahun datang dengan kavitas besar pada molar ketiga kanan bawah dan menginginkan perawatan tanpa pencabutan. Tiga minggu sebelumnya, dokter lain telah melakukan devitalisasi dan restorasi sementara. Pemeriksaan klinis menunjukkan tidak ada lesi periapikal dan uji perkusi negatif. Radiograf menunjukkan kelengkungan ringan pada saluran distal. RCT dilakukan menggunakan K-file pra-lengkung dengan sistem One Curve. Obturasi dilakukan dalam satu kunjungan, diikuti restorasi komposit langsung yang diperkuat dengan komposit serat pendek. Area distal direstorasi menggunakan matriks dan pita PTFE. Simpulan: RCT kunjungan tunggal pada molar ketiga mandibula dengan pulpa nekrotik dan periodontitis apikal asimptomatik dapat berhasil dilakukan dengan diagnosis akurat dan teknik yang tepat. Pendekatan konservatif ini menunjukkan bahwa pencabutan bukan satu-satunya pilihan.Kata kunci sekali kunjungan, perawatan saluran akar, molar ketiga, saluran melengkung, restorasi komposit.

Abstract

The diversity and habitat preferences of orchids in the natural tourist attraction area of R. Soerjo Forest Park (TAHURA) are not yet completely known. Lack of information and the activities of tourist visitors increase the risk of natural orchid habitat degradation. The aim of this research is to determine the diversity and habitat preferences of orchids in R. Soerjo Forest Park. The research design used a line transect method for orchid diversity data and a purposive sampling method with a plot measuring 10 × 10m for habitat preference analysis or environmental data. The research results show that there are 37 species of orchids in the natural tourist attraction area of R. Soerjo Forest Park, which is divided into 25 epiphytic orchids and 12 terrestrial orchids. The results of the Shannon-Wienner analysis show that the orchid diversity index value is 2.46, which is show a medium level of diversity. Dominant orchids grow at an altitude of 1,400–1,600 m.a.s.l. The most dominant orchid species are Nervilia punctata (558), Appendicula angustifolia (296), and A. elegans (130), with an evenness value of 0,32, 0,17, and 0,07. The dominance of N. punctata is influenced by the root shape, which is modified as a tuberous type. The results of redundancy analysis (RDA) show that the environmental variables that most influence the distribution of orchids are air temperature, soil pH levels, light intensity, and elevation.

Abstract

Polycythemia is a myeloproliferative neoplasm characterized by uncontrolled proliferation of red blood cells due to mutations in early hematopoietic cells, often linked to Janus kinase 2 (JAK2) gene mutations. Polycythemia vera (PV), the primary form of the disease, leads to increased blood viscosity and stasis, raising the risk of thrombotic events such as stroke and myocardial infarction. Secondary polycythemia results from hypoxic conditions, stimulating erythropoietin production. Diagnosis is confirmed through hemoglobin and hematocrit levels, with treatment aimed at reducing thrombosis and hemorrhage risks. Low-risk patients are treated with aspirin and phlebotomy, while high-risk cases may require cytoreductive therapies like hydroxyurea.In our case, a patient presented with necrosis and horizontal bone loss in tooth 36, complicated by polycythemia. Due to the increased risk of bleeding and inflammation, the decision was made to prioritize endodontic treatment, avoiding periodontal surgery. The patient, considered low-risk for PV complications due to the absence of thrombosis history, was managed conservatively. Preoperative coordination with hematologists was essential to optimize hematologic parameters and minimize potential risks.The goal of endodontic treatment was to disinfect and seal the root canal, reducing inflammation in the surrounding periodontal tissues and preventing reinfection. This approach allowed for effective management of the patient's oral condition while minimizing systemic risks. This case highlights the importance of a multidisciplinary approach in managing dental treatment for patients with polycythemia, ensuring both local and systemic complications are effectively addressed.

Abstract

The application of 35% hydrogen peroxide in intracoronal bleaching generates free radicals that shorten resin tags and weaken the bond strength of composite resin restorations. Although 35% sodium ascorbate can neutralize free radical residues, its molecular instability limits its effectiveness. The addition of surfactants may enhance both the penetration ability and stability of sodium ascorbate. This study aimed to investigate the effect of adding 0.4% surfactant to 35% sodium ascorbate on the length of resin tags in composite resin restorations following intracoronal bleaching. Thirty mandibular premolars were prepared with standardized Class I cavities measuring 2.7 mm in diameter and 6 mm in depth. A 35% hydrogen peroxide gel was applied to the cavities for five consecutive days. After bleaching, the samples were randomly assigned to three groups of ten teeth each. The first group was stored in an incubator for seven days before undergoing composite resin restoration. The second group received an application of 35% sodium ascorbate, which was then rinsed off before immediate composite restoration. The third group received an application of 35% sodium ascorbate combined with 0.4% surfactant, followed by rinsing and immediate composite restoration. Histological preparations were made using hematoxylin-eosin staining and observed under a light microscope at 400× magnification. Resin tag lengths were measured using the Image Raster application. The one-way ANOVA test revealed a statistically significant difference among the groups (p = 0.000). Post-hoc LSD analysis showed that resin tag lengths in the third group were significantly greater than those in both the first and second groups (p = 0.000 for both comparisons). These results indicate that the combination of 35% sodium ascorbate with 0.4% surfactant significantly increases resin tag length and may enhance the bonding performance of composite restorations following intracoronal bleaching.
