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.

Abstract

Background: The high level of public awareness regarding aesthetic values influences the evolution and selection of restoration materials. Nanofiller composite resin is an option in aesthetic restoration because it has good aesthetic qualities, mechanical properties and high wear resistance. Color changes that occur in nanofiller composite resin are undesirable because they disturb the aesthetic value and appearance. Color changes in restoration materials are influenced by the acidic pH contained in artificial saliva. Objective: This study aims to determine the effect of artificial saliva with a pH of 5 on the color change of nanofiller composite resin restoration materials. Methods: The research object is a nanofiller composite resin with a diameter of 10 mm, and a thickness of 2mm. The research was carried out by soaking nanofiller composite resin in artificial saliva and distilled water solution. The study was divided into 2 groups, namely the treatment group and the control group. Which is placed in an incubator at a temperature of 37˚ C for 24 hours. In the control group, samples were soaked in distilled water for 24 hours, and repeated for 7 days. In the treatment group, samples were soaked in artificial saliva for 4 hours, repeated for 7 days, followed by immersion in distilled water. The color parameters of the research subjects were measured using a Vita Easyshade V spectrophotometer before and after immersion in the control and treatment groups on the 7th day. The measurement results data after carrying out the normality test, T-test (dependent), and Wilcoxon test. Results: The results of this study showed a significant color change (p<0.05). Conclusion: There is an effect of artificial saliva with a pH of 5 on the color change of the nanofiller composite resin material.
