Abstract

Background: To achieve an aesthetic restoration, it is necessary to choose the right technique and material. Nanofiller composite resin is an option in aesthetic restoration because it has high aesthetic qualities, mechanical properties, and wear resistance. The presence of discoloration in composite resin restorations is undesirable because it interferes with the aesthetic value and appearance. Changes in the color of the restoration caused by extrinsic factors are influenced by color pigments and acidic pH contained in the food and beverages consumed, for example, red beetroot. Objective: This study aims to determine the effect of consumption of red beetroot on the color change of nanofiller composite resin, by immersing it in red beetroot juice. Methods: The object of this research is a cylindrical nanofiller composite resin with a diameter of 10 mm and a thickness of 2 mm. The research was conducted by immersing the nanofiller composite resin in red beetroot juice and aquadest. The study was divided into 2 groups, the control group and the test group, which were placed in an incubator with a temperature of 37oC for 24 hours. In the treatment group, samples were immersed in red beetroot juice for 4 hours for 7 days, followed by immersion in distilled water. In the control group, samples were immersed in distilled water for 24 hours. The color parameters of the research subjects were measured using Vita Easyshade V, before and after treatment for 7 days. After the normality test, the acquired data was statistically tested using Mann-Whitney test and T-test (Independent). Results: The results of this study showed a significant color change (p<0.05). Conclusion: There is an effect of soaking with red beetroot juice on the color change of the nanofiller composite resin.

Abstract

Background: Dental caries remains as one of the most prevalent oral diseases worldwide, especially in developing nations like Indonesia. Untreated caries may lead to pulp involvement, prompting vital pulp therapy (VPT) to protect pulp vitality. The success of VPT is dependent on the biological and physical properties of the capping materials. Traditional pulp capping materials, such calcium hydroxide Ca(OH)₂ and mineral trioxide aggregate (MTA), show bio-activity but are limited by issues of solubility, manipulation, and bio-compatibility. Consequently, calcium phosphate cement (CPC) and calcium sulfate hemihydrate (CSH) with acemannan (Ace) have been explored as potential alternatives. Purpose: This research aimed to evaluate the potential of a mixture containing CPC-CSH-Ace as a bio-active material for vital pulp therapy. Methods: CPC–CSH–Ace was formulated by combining 70 wt% CPC and 30 wt% CSH with acemannan concentrations of 3 wt%, 5 wt%, and 10 wt%. Calcium hydroxide (Dycal, Dentsply) and MTA (Bio MTA+, Cerkamed) were used as controls. Particle size was measured using a Particle Size Analyzer (Horiba SZ-100), surface morphology and calcium ratio were tested with SEM–EDS, and crystal structure was determined using XRD (Rigaku Miniflex). Data were examined utilizing one-way ANOVA and subsequent post-hoc testing (p < 0.05). Results: CPC–CSH–Ace exhibited smaller particle sizes, smoother surfaces, higher Ca/P ratios, and more defined hydroxyapatite peaks than Ca(OH)₂ and MTA. Conclusion The combination of CPC–CSH-Ace showed significant chemical and physical characteristics and has promise as a new bio-active material for vital pulp therapy.

Abstract

Background: Endodontic success depends on precise execution. Iatrogenic complications such as ledge formation and excessive access cavity preparation can obstruct canal negotiation, impair disinfection, weaken tooth structure, and increase treatment failure. Purpose: This case report describes the management of a ledge and an overprepared access cavity in a mandibular second molar. Case: A 33-year-old female was referred with tooth 37 restored using a subgingival temporary filling. Radiographs revealed mesial radiolucency, an excessively extended access cavity, and a ledge in the mesial root canal. Case Management: Treatment was performed under rubber dam isolation. Temporary restoration and caries were removed, followed by artificial wall construction with resin composite. Pre-curved K-files (#10, #15) were used to bypass the ledge and establish a glide path and determine the working length. Rotary glide path instruments and heat-treated NiTi files were used to shape up to size #25/.04, with irrigation using 5.25% NaOCl and 17% EDTA. After intracanal calcium hydroxide medication, obturation was completed using bioceramic sealer, warm vertical compaction in the mesial root, and a single-cone technique in the distal root. A flowable bulk-fill composite was placed as the intracanal barrier, and final restoration was completed with packable composite. Conclusion: Ledges obstruct instrumentation and disinfection, requiring flexible pre-curved files and careful negotiation to re-establish canal patency. Excessive access cavity preparation compromises peri-cervical dentin, increasing susceptibility to structural failure. Bulk-fill flowable composite offers good marginal adaptation and may improve restoration durability. Thorough planning, controlled instrumentation, and appropriate restorative materials are essential to manage such complications effectively.
