Abstract

Introduction: Conditions of the temporomandibular joint (TMJ) are affected by changes in movement and load during the joint’s function, which can cause morphological changes in hard tissues, such as the condyle. Panoramic radiographs can provide an indication of changes in hard tissues in TMJ. Objectives: The aim of this study was to determine whether there was any correlation between mandibular condyle shapes as seen on panoramic radiographs and TMJ conditions in adult female participants. Methods: The participants of this study were 75 adult female patients who underwent a panoramic radiograph examination conducted at the Maranatha Dental Hospital Radiology Unit. The patients were clinically examined based on the Research Diagnostic Criteria for Clinical Temporomandibular Disorder (RDC/TMD) questionnaire and also their panoramic radiographs. The data from the patients were categorized into four groups according to the RDC/TMD: normal, muscle disorders, disc displacement, and other joint diseases. Next, the radiographs were analyzed by two observers to determine the condyle shapes. Condyle shapes were classified into four groups: ovoid, flat, erosion, and osteophyte. Result: This study showed that of 75 patients, the right TMJ was normal in 34 patients, 2 patients had muscle disorders, 24 demonstrated disc displacement, and 15 had other joint diseases. For the left side of the TMJ, 22 radiographs were normal, 2 revealed muscle disorders, 35 identified disc displacement, and 16 showed other joint diseases. There was a strong agreement between the two observers in determining the right (κ=0.681) and left condyle shapes (κ=0.652). All participants’ findings indicated that condyle shapes and TMJ conditions are highly correlated for both the right (η2=0.889) and left condyle (η2=0.762). Conclusion: This study concluded that mandibular condyle shapes seen on panoramic radiographs and TMJ conditions in adult female participants were highly correlated.

Abstract

Introduction: Glass ionomer cement (GIC) is a tooth-colored restorative material that is often used by clinical practitioners because it can release fluoride, is easy to apply to teeth and has minimal preparation techniques. The erosion and moisture-sensitive nature of GIC becomes a problem for a long-lasting aesthetic restoration. Therefore, modifications were made to improve its mechanical properties by adding nanochitosan (NCH) from horn beetle (Xylotrupes gideon). Objective: This study aimed to evaluate the effect of adding horn beetle nanochitosan to GIC liquid on the surface hardness and compared with conventional GIC. Methods: Forty cylindrical samples of GIC (GC Fuji® IX Extra, Tokyo-Japan, Lot 1912201) with a diameter of 4 mm and a thickness of 6 mm were divided into 4 groups, namely the GIC control group, GIC modified with 0.5wt%, 1wt%, 2 wt% nanochitosan. Each sample was immersed in artificial saliva for 24 hours and 7 days. Surface hardness before and after immersion was tested using a Vickers Microhardness tester (Shimadzu, Japan). The data were analyzed using the Kruskal Wallis test to determine the effect of horn beetle nanochitosan addition and the Wilcoxon Signed-Ranked test to determine the effect of immersion time on GIC surface hardness. Results: The Kruskal Wallis statistical test showed significant difference (p<0.05) between the control group and the 24 hours treatment group with the addition of 2wt% nanochitosan, which was the highest surface hardness value (133.1 ± 49.0 HV), followed by 1wt% (127.4 ± 25.5 HV) and 0.5wt% (117.7 ± 22.5 HV). The Wilcoxon Signed-Ranked test statistic also showed a significant difference (p<0.05) between the 24-hour and 7-day immersion time with the surface hardness value at 24 hours immersion greater than 7 days. Conclusion: The addition of 0.5wt%, 1wt% and 2wt% horn beetle nanochitosan can increase the GIC surface hardness value. ABSTRAK Pendahuluan: Glass ionomer cement (GIC) merupakan bahan restorasi sewarna gigi yang sering digunakan oleh praktisi klinis karena dapat melepaskan fluor, mudah diaplikasikan pada gigi, dan memiliki teknik preparasi yang minimal. Erosi dan sifat sensitif kelembaban dari GIC menjadi masalah untuk restorasi estetika yang tahan lama. Oleh karena itu, dilakukan modifikasi untuk meningkatkan sifat mekaniknya dengan menambahkan nanokitosan (NCH) dari kumbang tanduk (Xylotrupes gideon). Tujuan: Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan nanokitosan kumbang tanduk ke dalam cairan GIC terhadap kekerasan permukaan dan dibandingkan dengan Semen Ionomer Kaca (SIK) konvensional. Metode: Empat puluh sampel silinder GIC (GC Fuji® IX Extra, Tokyo-Japan, Lot 1912201) dengan diameter 4 mm dan ketebalan 6 mm dibagi menjadi 4 kelompok, yaitu kelompok kontrol GIC, GIC dimodifikasi dengan nanokitosan 0,5wt%, 1 wt%, 2wt%. Setiap sampel direndam dalam saliva buatan selama 24 jam dan 7 hari. Kekerasan permukaan sebelum dan sesudah perendaman diuji menggunakan Vickers Microhardness tester. Data dianalisis menggunakan uji Kruskal Wallis untuk mengetahui pengaruh penambahan nanokitosan kumbang tanduk dan uji Wilcoxon Signed-Ranked untuk mengetahui pengaruh waktu perendaman terhadap kekerasan permukaan GIC. Hasil: Uji statistik Kruskal Wallis menunjukkan perbedaan bermakna (p<0,05) antara kelompok kontrol dan kelompok perlakuan perendaman 24 jam dengan penambahan nanokitosan 2wt% yang merupakan nilai kekerasan permukaan tertinggi (133,1 ± 49,0 HV), diikuti sebesar 1wt% (127,4 ± 25,5 HV) dan 0,5% (117,7 ± 22,5 HV). Statistik uji Wilcoxon Signed-Ranked juga menunjukkan perbedaan yang nyata (p<0,05) antara lama perendaman 24 jam dan 7 hari dengan nilai kekerasan permukaan pada perendaman 24 jam lebih besar dari 7 hari. Kesimpulan: Penambahan nanokitosan kumbang tanduk 0,5wt%, 1% , dan 2wt% dapat meningkatkan nilai kekerasan permukaan GIC.

Abstract

Background: Losing teeth can cause problems such as the emergence of mastication, aesthetics, and phonetics. One of the solutions to restore these functions is dental implant. This method is in demand because apart from being able to restore function, the implant will also protect the jawbone from the process of resorption due to tooth loss. This is possible because dental implants are surgically implanted into the jawbone, then dentures can be placed over them to adapt the oral condition Case report: A 63-year-old woman with controlled hypertension came with complain of extracted lower right tooth 1 year ago and she wanted a fixed prosthesis to replace this tooth. She had not good experience with removeable denture at upper jaw. the jawbone has undergone resorption due to tooth loss which was not immediately rehabilitated. A single unit Straumann BLT dental implant of diameter 3.3 mm x height 10 mm is placed on this patient after treatment planning with radiograph image and study model analysis. Screw-cemented retained prosthesis was delivered on the implant to restore the function and aesthetic of the missing 46 tooth. Conclusion: Good planning and proper procedure during implant placement and restoration will lead to an excellent long-term aesthetic and functional outcome.

Abstract

Teeth that have undergone endodontic treatment often lose significant structure, requiring strong and durable restorations to prevent clinical failure and support long-term function. This study aimed to evaluate the effect of post-curing time on the hardness, diametral tensile strength (DTS), and water sorption of 3D-printed resin composites. An experimental study was conducted using 80 disc-shaped resin composite specimens divided into four groups based on post-curing time duration (5 minutes, 10 minutes, no curing, and control). Hardness was measured using the Vickers Hardness test, DTS with a Universal Testing Machine, and water sorption through immersion in artificial saliva. Hypothesis testing was performed using ANOVA and Post Hoc Tamhane tests. The results showed that increasing the post-curing time significantly improved hardness but did not affect DTS and water sorption. The group with 10 minutes of post-curing time achieved the best results in hardness improvement. The findings indicate that post-curing time positively influences the mechanical and physical properties of resin composites, particularly the hardness of 3D-printed materials. This process enables better polymer densification, resulting in stronger materials resistant to degradation in the oral environment. The duration of post-curing time significantly contributes to optimizing the mechanical and physical properties of 3D-printed resin composites, making it an essential step in manufacturing restorations for the long-term success of dental restorations.

Abstract

Background: Xylotrupes gideon is a harmful insect because it damages the shoots of coconut trees. Xylotrupes gideon has begun to be used in the form of nanochitosan as an alternative in dentistry. The addition of nanochitosan to Glass Ionomer Cement (GIC) material is a modification to improve the properties of GIC, such as surface roughness caused by acidic conditions (critical saliva pH). Nano-sized chitosan is able to increase stability and better absorption, thus inhibit demineralization and increase tooth hardness. This research aimed to investigate the effect of nanochitosan from Xylotrupes gideon on the surface roughness of GIC at critical saliva pH.Method: This research type conducted is an experimental laboratory. Samples of 10 mm (height) x 2 mm (diameter) divided into 2 groups, (A) Unmodified GIC (control group), (B) GIC modified with 10% nanochitosan solution. Samples of the treatment and control group are stored in the incubator at 370C for 1 hour before early surface roughness testing and continued in critical saliva pH (5,5) for 7 days in the incubator before the final test. The surface roughness tester using sutrotonic s-100 series.Result: There was an increase in the surface roughness of conventional GIC by 0.133 µm and GIC nanochitosan by 0.122 µm. The results of the paired t-test before and after immersion in the two groups showed that there was a significant difference (p <0.05) between conventional GIC and nanochitosan GIC. The independent t-test results showed that there was no significant difference (p> 0.05) between the nanochitosan GIC and conventional GIC.Conclusion: Nanochitosan can reduce the surface roughness value of GIC at critical saliva pH, although there is no significant difference to conventional GIC.

Abstract

ABSTRACT Background: Tooth loss can be caused by periodontal disease, caries, and other factors. Dental implants made of titanium are a common solution to replace tooth loss. Titanium grade 5 (Ti-6Al-4V) is often chosen for an implant. Modern commercial implant surface roughness (Ra) ranges from 1 to 2 μm. Surface roughness has an important role in osseointegration. The acid etching method can be used to improve surface roughness. This study evaluates titanium alloy surface roughness after etching with varying concentrations of H3PO4 acid.Method: A laboratory experiment with a pre-test and post-test group design. 25 titanium alloy samples were divided into 5 groups (n=5) and treated with saline, HCl 37%, and H3PO4 acid 38%, 48%, and 58%. Surface roughness was measured using a surface roughness tester, while EDS and SEM tests analyzed titanium composition and surface characteristics.Result: The titanium used in this study is a titanium alloy. Surface roughness modification using acid had a higher roughness compare to saline with significant different (p<0.05). Surface roughness in the group H3PO4 48% and 58% had a lower roughness compared to HCl 37% but no significant different (p>0.05). Referring to the SEM results, each acid showed morphological changes on the surface and for saline there were no morphological changes.Conclusion: Varying concentrations of H3PO4 acid can effectively improve the surface roughness of titanium alloys, with solutions at 48% and 58% demonstrating similar effectiveness to 37% HCl acid.
