Abstract

Introduction: The anti-apoptotic protein EGFR is typically overexpressed in the majority of head and neck squamous cell carcinomas (HNSCC) and has been targeted for genetic therapy. The Clausena excavata plant is an evergreen shrub that has been widely used for various disease therapies, including cancer. Coumarin and carbazole alkaloids are the plant's primary active ingredients. This study aims to determine the molecular interaction between EGFR and several coumarins (clauslactone E, dentatin, nordentatin, clausenidin) and carbazole alkaloids (7- hydroxyheptaphylline, clausine E, 2,7 - dimethoxy - 9H - carbazole - 3- carbaldehyde,and 2,7 – dimethoxy - 9H - carbazole – 3-carboxylic acid). Methods: This research was carried out in silico using the molecular docking method. Molecular docking analysis was performed using AutoDock Vina, AutoDockTools 1.5.6., Pymol, and Discovery Studio Biovia 2021. The three-dimensional structure of the EGFR protein was retrieved from the RCSB Protein Data Bank. Ligands were obtained from the PubChem Compound Database. The comparison ligand was doxorubicin. Molecular docking results were analyzed based on binding affinity, amino acid interactions, visualization of docking results, and Lipinski's rule of five. Results: All of the investigated ligands with the EGFR receptor had strong binding affinity (-6.8 and -8.3 kcal/mol), almost the same as the comparison ligand (-8.2 kcal/mol). Each interaction also produced a different number of amino acid residues. Conclusion: These four coumarin compounds and four carbazole alkaloid compounds are considered potential EGFR inhibitors and anticancer candidates.KeywordMolecular docking, anticancer, oncogene protein, natural compunds

Abstract

Introduction: Toothbrushing is a fundamental daily practice for plaque removal. Dental plaque is a complex microbial biofilm that serves as a primary etiological factor for caries, gingivitis, and periodontitis. While manual toothbrushes (MTB) are widely used and considered effective, powered toothbrushes (PTB) are found to be a better alternative with numerous clinical trials proving their efficacy. Objective: To evaluate the effectiveness of PTB compared to MTB in reducing plaque and gingivitis based on existing literature. Methods: A systematic search was conducted to obtain clinical trials that compares plaque and gingivitis reduction with PTB and MTB usage across all age groups, using three databases - Pubmed, Scopus, and ScienceDirect. Discussion: 18 studies (69%) fully supported the hypothesis that PTB caused significantly greater reduction in plaque and gingivitis than MTB. However, seven studies (27%) found no significant differences between the two types, while one study (4%) partially supported the hypothesis, where it found PTB to be superior for plaque reduction but not for gingivitis. Overall, PTB were superior in reducing plaque and gingivitis, particularly in general populations. However, the benefits were less consistent in specific populations, such as orthodontic patients and individuals with special needs. Both oscillating-rotating and sonic PTB were comparable in their effectiveness. Conclusion: PTB are more effective than manual toothbrushes for improving plaque and gingival health in most populations. Further research is needed to address specific populations and optimise oral hygiene strategies tailored to their needs.

Abstract

Animal models are vital in dental research for studying dentomaxillofacial anomalies, disease mechanisms, and therapeutic strategies. Conventional models, such as those using rodents and higher mammals, provide valuable insights but raise ethical, financial, and translational challenges. Zebrafish (Danio rerio), widely established in biomedical sciences, offer distinctive advantages including genetic similarity to humans, transparent embryos, rapid development, and low maintenance costs. Despite their potential, their use in dental research remains relatively limited. This review evaluates current and emerging applications of zebrafish in dentistry based on peer‑reviewed literature and institutional resources. Research highlights three main areas. In tooth and craniofacial development, zebrafish contribute insights into odontogenesis, regeneration, and congenital anomalies through continuous tooth replacement and conserved pathways such as bone morphogenetic protein (BMP) and Hedgehog. In dental material studies, zebrafish embryos serve as sensitive models for assessing systemic and craniofacial toxicity of fluorides, nanoparticles, alloys, bioceramics, and resin-based monomers. In oral cancer research, transparent zebrafish lines and xenograft models enable real-time visualisation of tumor progression, metastasis, and treatment response, supporting high-throughput drug screening. Although limitations such as the absence of permanent dentition and anatomical differences restrict direct translation, zebrafish provide a rapid, ethical, and cost-effective complement to mammalian models—advances in genetics and imaging promise to expand their role in dental research and strengthen their translational relevance.

Abstract

Introduction: Nutritional status is one of the most important things that parents must pay attention to, especially when the child is in the golden period of growth, which consists of the period of growth and development, including tooth eruption. Tooth eruption is influenced by various factors, one of which is nutritional factors. Mothers' health status may then determine their children's primary dentition status, and also the child's status itself. This study aims to analyze factors related to delayed tooth eruption in children aged 6–24 months. Methods: This research was a cross-sectional study conducted among 464 children aged 6–24 months. The sampling method employed was a total sampling technique undertaken in 10 villages within the Pandeglang district, West Java. Tooth eruption time used the Primary Tooth Development figure by the American Dental Association (ADA). Statistical analysis was performed using chi-square and logistic regression. Research ethics were obtained from YARSI University. Results: There was a significant relationship between delayed tooth eruption and mother’s Body Mass Index (BMI), nutritional status of children, and gender, with a value of ρ<0.05. Female sex (AOR=1.51), stunting (AOR=1.86), and underweight (AOR=1.78) increased the odds of delayed eruption. Conclusion: Nutritional status influences eruption timing. Integrating oral assessments into routine child growth monitoring could improve early detection of developmental risks in children aged 6 – 24 months.  Faktor-faktor yang mempengaruhi keterlambatan erupsi gigi pada anak usia 6-24 bulan: studi cross-sectionalPendahuluan: Status gizi merupakan faktor krusial yang perlu diperhatikan oleh orang tua, terutama pada masa perkembangan awal anak, yang meliputi periode pertumbuhan pesat, perkembangan fisiologis, serta erupsi gigi. Erupsi gigi dipengaruhi oleh berbagai faktor, salah satunya adalah faktor gizi. Status kesehatan ibu menentukan status gigi sulung anak-anak mereka, demikian pula status anak itu sendiri. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang berhubungan dengan keterlambatan erupsi gigi pada anak usia 6 - 24 bulan. Metode: Penelitian ini merupakan penelitian potong lintang yang dilakukan di antara 464 anak usia 6 - 24 bulan. Metode pengambilan sampel yang digunakan adalah teknik total sampling yang dilakukan di 10 desa di kabupaten Pandeglang, Jawa Barat. Waktu erupsi gigi menggunakan angka Perkembangan Gigi Sulung oleh American Dental Association (ADA). Analisis statistik dilakukan dengan menggunakan chi-square dan regresi logistik. Hasil: Terdapat hubungan yang signifikan antara keterlambatan erupsi gigi dengan IMT ibu, status gizi anak, dan jenis kelamin, diperoleh nilai p=0,05. Jenis kelamin perempuan (AOR=1,51), stunting (AOR=1,86), dan berat badan kurang (AOR=1,78) meningkatkan kemungkinan erupsi tertunda. Simpulan: Status gizi secara memengaruhi waktu erupsi. Mengintegrasikan pemeriksaan gigi ke dalam pemantauan pertumbuhan anak secara rutin dapat meningkatkan deteksi dini risiko pada anak usia 6-24 bulan.
