Abstract

Reduction of the amount of tooth roots which are embedded in their periodontium could cause tooth mobility. Splinting a weaker tooth with a more stable one, and using the principle of the multiple-root stabilization is one way to overcome tooth mobility. Temporary splinting aims to prevent pathological migration, restore masticatory function, stabilize teeth before/after surgery, and evaluate the prognosis of periodontal treatment. The use of intracoronal splint is still controversial because there are only a few studies that have evaluated the effect of splinting on periodontal health. We report two cases to evaluate the effect of intracoronal splint on periodontal treatment. Two periodontal cases that use intracoronal splint before, during, and after periodontal regenerative therapy using bone graft. Causes of tooth mobility were removed and the splinting principles, terms and guidelines were mastered to get the maximum results of periodontal treatment. Both cases were evaluated radiographically 10 months after treatment. In these cases, intracoronal splint has supported the therapy before, during, or after surgery. Splinting is only for adjunctive therapy, and does not serve as the sole method in getting occlusal stability.

Abstract

ABSTRAKPendahuluan: Karies merupakan masalah gigi yang paling umum dijumpai dan dapat direstorasi dengan resin komposit. Kelemahan resin komposit adalah mudah mengalami pengerutan selama polimerisasi sehingga meningkatkan risiko terjadinya karies sekunder akibat terbentuknya kebocoran nano antara struktur gigi dengan restorasi. Hal ini memerlukan bahan tambahan khususnya dalam bahan perekat sehingga dapat meningkatkan kekuatan ikatan restorasi dan mengurangi risiko karies sekunder, salah satunya dengan penambahan nanopartikel tembaga. Penelitian ini bertujuan untuk mengetahui efektivitas penambahan nanopartikel tembaga terhadap kekuatan  ikatan resin – dentin dan kebocoran nano antara permukaan resin dan jaringan keras gigi. Metode: Jenis penelitian telaah sistematis dengan memasukkan kata kunci pada database PubMed, EBSCO, dan Google Scholar dengan rentang waktu 2012 – 2022. Telaah sistematis ini dibuat berdasarkan guideline PRISMA dan dievaluasi dengan JBI Critical Appraisal tools. Kriteria inklusi pada penelitian ini meliputi seluruh studi eksperimental yang sesuai dengan topik penelitian. Hasil: Kekuatan ikatan resin – dentin terus meningkat pada penambahan konsentrasi nanopartikel tembaga hingga 0,5%, karena pada konsentrasi yang lebih tinggi NpCu bertindak sebagai plasticizer yang dapat mengganggu keseimbangan campuran monomer. Selain itu tembaga juga berpotensi meningkatan kekuatan jaringan kolagen dan ketahanan terhadap enzim proteolitik sehingga mengurangi kebocoran nano. Simpulan: Penambahan nanopartikel tembaga (NpCu) dalam bahan perekat restorasi gigi efektif dalam meningkatkan kekuatan ikatan resin – dentin dan mengurangi kebocoran nano.KATA KUNCINanopartikel, tembaga, resin komposit, bahan perekat, kekuatan ikatanEffectiveness of copper Nanoparticles addition in dental restorative adhesives on the Dental – Restoration  Bond Strength : systematic reviewABSTRACTIntroduction: Dental caries is the most common dental problem that can be restored overcome by composite resins. The weakness of composite resins is that they tend to shrink during polymerization, thereby increasing the risk of secondary caries formation due to the formation of nano-leakage between the tooth structure and the restoration. Therefore, additional materials are required, especially in adhesives, to strengthen the restoration and reducing the risk of secondary caries, such as adding copper nanoparticles. This study aimed to determine the effectiveness of copper nanoparticles addition on the micro – tensile bond strength (µTBS) and nanoleakage between the resin – dentin interface. Methods: Systematic study uses a research method by entering keywords in the PubMed, EBSCO, and Google Scholar databases for the 2012 – 2022 time period. This systematic study was made based on PRISMA guidelines and evaluated with JBI Critical Appraisal tools. Inclusion criteria in this study were all experimental studies under the research topic. Results: Micro – tensile bond strength (µTBS) continues to increase with the addition of copper nanoparticle concentrations up to 0.5%, because at higher concentrations CuNp acts as a plasticizer. CuNp also increases the strength of collagen network enzymes and resistance to proteolytics, thereby reducing nano-leakage. Conclusion : Copper nanoparticles addition in the dental restoration adhesive were effective in increasing the micro – tensile bond strength and decreasing nanoleakage.KEY WORDSnanoparticles, copper, composite resin, bonding agent, bond strength

Abstract

Staphylococcus epidermidis is a common pathogen responsible for peri-implantitis, an infection localized around dental implants. Its virulence is largely attributed to biofilm formation, which enhances resistance to antibiotics and immune defenses. The challenge of treating S. epidermidis is further compounded by its resistance to several antibiotics, including methicillin. This study aimed to evaluate the antibacterial and anti-biofilm properties of a copper-zinc (Cu-Zn) metal alloy and its efficacy when integrated with beta-tricalcium phosphate (β-TCP) as a graft medium against S. epidermidis using in vitro methods. This research employs Staphylococcus epidermidis ATCC 12228. Antibacterial activity was assessed using Direct contact test and viability count via Colony-Forming Unit (CFU) analysis, while biofilm formation was evaluated using the tube adherence method. Increasing copper and zinc concentrations enhanced antibacterial efficacy, with Cu-Zn-β-TCP suspensions showing significantly greater antibacterial activity (p = 0.01) and improved anti-biofilm properties compared to Cu-Zn suspensions without β-TCP. The incorporation of copper and zinc effectively inhibited bacterial growth and biofilm formation of S. epidermidis. Furthermore, the Cu-Zn alloy demonstrated higher efficacy when used in conjunction with β-TCP as a graft medium, suggesting its potential for managing peri-implantitis.

Abstract

Insufficient oral health knowledge contributes to high prevalence of oral disease among primary school students. Large-group lectures are commonly used in community services but may not be the most effective learning method. Studies suggest that small-group settings foster better learning environments. This study examines knowledge changes before and after oral health education (OHE), comparing the effectiveness of large- and small-group settings. Fifty-three students aged 10 to 12 years were divided into two groups: Group A (21 students) received OHE in a large lecture-style setting, while Group B (32 students) received OHE in smaller groups of 4 to 8 students. A pre-test was administered before OHE session, followed by a post-test to assess knowledge improvement. Statistical analysis showed significant pre-test to post-test improvement in both groups (p < 0.001). The gain in test scores for group A (27.62+18.69) was greater than that of group B (17.50+10.47), which was also statistically significant (p=0.028). These findings suggest that OHE effectively improves knowledge, with larger groups showing greater score improvement, potentially due to factors such as group dynamics, the physical environment, or learning aids.
