Abstract

Tooth discoloration is categorized into intrinsic and extrinsic types, with the latter caused by external staining agents such as pigmented beverages (e.g., black tea). Whitening toothpastes are commonly used to address extrinsic discoloration, though chemical-based formulations may lead to side effects. Consequently, natural alternatives, including activated charcoal and bentonite, are gaining attention as whitening agents. This study aimed to evaluate the effects of activated charcoal and bentonite toothpaste on extrinsic tooth discoloration. A control group pretest-posttest design was employed, involving 48 premolar teeth divided into four groups. Samples were stained by immersion in a black tea solution (400 mL water, 4 tea bags) for 4 hours daily over 13 days, simulating 7 months of tea consumption. Color measurements were conducted using a spectrophotometer before and after brushing. Brushing was carried out using an electric toothbrush with 0.5 g of toothpaste and 1 mL of distilled water for 2 minutes, twice daily, over 10 days. Repeated ANOVA analysis revealed significant differences in ΔE, ΔL, and ΔC values (p < 0.05). Activated charcoal toothpaste produced a marked lightening effect and increased color intensity, although no change was observed at the cervical region of the teeth. These findings suggest that activated charcoal may serve as an effective natural agent for managing extrinsic discoloration while further research is needed to clarify its long-term effects and clinical applications.

Abstract

The β-TCP material is a material of ceramic that often used in the medical and dental fields as a bone substitute material because it has biocompatible, bioresorbable and osteoconductive properties. Apart from that, this material is also biocompatible with tooth tissue, is non-inflammatory, and can regenerate dentin. Several studies have shown that the properties of β-TCP material can be a candidate for pulp capping material. These studies have also been carried out on experimental animals and showed good results. This article reviews the potential of β-TCP as a candidate pulp capping material in dentistry.

Abstract

The process of dental demineralization can lead to the dissolution of minerals in hydroxyapatite crystals, increasing interprismatic spaces and decreasing enamel hardness. This demineralization can be inhibited through remineralization, supported by natural ingredients such as brown anchovy, which have potential as remineralizing agents. The remineralization process can be observed through changes in enamel microhardness and microporosity. Objectives: This article aims to provide information about the potential of brown anchovy and its effects on enamel microhardness and microporosity. Conclusion: There is potential of brown anchovy and its benefit in teeth remineralization.

Abstract

Background: Inadequate dental restorations may disrupt the coronal seal and permit microleakage, allowing bacterial penetration into the root canal system. Persistent microbial contamination can induce a host-mediated inflammatory response in the periapical tissues, resulting in apical periodontitis. Root canal treatment is indicated to eliminate intracanal infection through effective cleaning, shaping, and disinfection, thereby supporting periapical healing. Objective: This case report describes the endodontic management of chronic apical periodontitis associated with an inadequate restoration in a mandibular anterior tooth, highlighting the clinical decision-making and treatment protocol to achieve periapical healing. Case report: A 34-year-old female patient presented to RSGM FKG USAKTI, with a chief complaint of a dislodged restoration on her lower left anterior tooth, which had been restored approximately one year prior. Intraoral examination revealed a cavity on the disto-palatal surface of tooth 32. Radiographic examination showed caries reaching the pulp on the distal surface, accompanied by apical periodontitis. At the initial visit, caries removal, access cavity preparation, and biomechanical preparation of the root canal system were performed. Root canal obturation was completed at a subsequent visit, followed by placement of a definitive direct composite resin restoration one month later. Conclusion: Multi-visit root canal treatment followed by definitive composite resin restoration was successfully performed, demonstrating effective management of apical periodontitis secondary to inadequate restoration in a mandibular anterior tooth.

Abstract

Background: Endodontically treated teeth are prone to biomechanical failure due to substantial structural loss, often necessitating fiber post–core and Zirconia crown restorations to re-establish tooth integrity and function. The choice of fiber post–core and Zirconia crown is determined by the amount of remaining tooth structure. Case Description: A 38-year-old male presented with a two-month history of throbbing pain in tooth 37, accompanied by discomfort during mastication. The patient had been self-medicating with mefenamic acid and reported no systemic illnesses. Intraoral examination revealed moderate oral hygiene (OHI-S 2) and a large occlusal cavity with a pulp polyp (Black Class II, Mount–Hume 2.4, ICDAS D6). Cold testing elicited a positive response, with tenderness to percussion but normal mobility and probing depths. Radiographic evaluation demonstrated pulp chamber radiolucency, widening of the periodontal ligament space, thickening of the lamina dura, and periapical radiolucency. The diagnosis was symptomatic irreversible pulpitis with apical periodontitis. The patient underwent root canal therapy followed by post–core and crown restoration. Discussion: Fiber-reinforced composite (FRC) posts provide dentin-like elasticity, favorable esthetics, and superior fracture resistance compared to metal posts, allowing more uniform stress distribution in endodontically treated teeth. The use of an FRC post combined with a Zirconia crown following root canal therapy successfully restored the tooth’s structure, function, esthetics, and long-term retrievability. Conclusion: Fiber post–core and Zirconia crown restoration is an effective approach for rehabilitating endodontically treated teeth at risk of biomechanical failure, offering dentin-like elastic properties and uniform stress distribution to optimize functional and esthetic outcomes.
