From Macro to Micro: The Rise of Nanoparticles in Endodontics | chapter 10 | Medical Science: Recent Advances and Applications Vol. 10

 

Nanotechnology has emerged as a transformative approach in endodontics, offering innovative strategies to overcome limitations of conventional therapies. Nanoparticles—ultrafine materials sized between 1 and 100 nm—exhibit unique physicochemical and biological properties that enhance antimicrobial efficacy, bioactivity, and mechanical performance of dental materials. This review comprehensively explores diverse nanoparticles, including hydroxyapatite, titanium dioxide, graphene, chitosan, carbon nanotubes, bioactive glass, silver, and copper nanoparticles, detailing their mechanisms of action, clinical applications, and potential in endodontics. These nanomaterials demonstrate capabilities such as biofilm disruption, reactive oxygen species generation, dentinal tubule occlusion, remineralisation, mechanical reinforcement, and regenerative support. Despite their promising therapeutic potential, challenges remain regarding cytotoxicity, stability, controlled release, cost, and regulatory approval. Addressing these barriers through rigorous research and clinical trials may pave the way for nanoparticle-based interventions to become integral components of predictable, long-lasting endodontic treatment outcomes. This review provides a valuable reference for researchers and clinicians seeking to integrate nanotechnology into more effective endodontic treatments.

Comparative Evaluation of Compressive and Flexural Strengths of Two Resin-based Core Build-up Materials with an Alkasite Material: An In-vitro Approach | Chapter 7 | Medicine and Medical Research: New Perspectives Vol. 4

Aim: The present study compares and evaluates the compressive and flexural strengths of two resin-based core build-up materials with an alkasite material.

Background: Several dental materials have been used for core build-up procedures, some as direct and some as indirect, such as a custom cast post and core. The material used for direct core build-up was not specifically developed for this purpose but found applications in core build-up due to properties such as fluoride release, adhesion to the tooth structure, choice of curing mechanism, and better handling properties to name a few.

Materials and Methods: ParaCore®, Tetric® N-Ceram^TM Bulk-fill composite, and Cention N were used. A total of 90 specimens were prepared. Customized cylindrical split molds of dimension 6 ± 1 mm (height) × 4 ± 1 mm (diameter) were used to fabricate 15 samples of each core material for testing the compressive strength and rectangular split metal molds of dimensions 25 ± 1 mm (length) × 2 ± 1 mm (width) × 2 ± 1 mm (height) were used to fabricate 15 samples of each core material for testing the flexural strength. Then the samples were tested using a Universal testing machine (UTM). Data were analyzed using a statistical package for social sciences (SPSS) version 22.0 (SPSS Inc, Chicago IL). Mean values of the experimental groups were compared using one-way ANOVA (Analysis of variance) and intergroup comparisons were made based on Post hoc values from Tukey’s test, at a 5% level of significance (p ≤ 0.05).

Results: The compressive and flexural strengths of Cention N were significantly less than ParaCore® but higher than Tetric® N-Ceram^TM Bulk-fill core build-up material. The estimated p value for compressive strength was p = 0.013 and for flexural strength was p = 0.004. Compressive and flexural strength, Cention N exhibits lower microleakage, prevents the recurrence of caries (due to long-term release of fluoride, calcium, and hydroxyl ions), has proximal contact tightness, has a dual cure mechanism and possesses superior micro-hardness and fracture resistance properties.

Conclusion: Within the limitations of this study, it was concluded that Cention N can be used as an alternative to other core build-up materials.

Clinical Significance: Cention N had the added advantage that self-cure polymerization alone was sufficient to achieve good physical properties when compared to the other two resin-based core build-up materials.

Psychological Evaluation of Orthodontic Patients | Book Publisher International

 Adult psychology examines the difficulties, stages, and diverse influences that children face as they grow into functioning adults, whereas child psychology refers to the interaction between a kid's conscious and subconscious minds. With the support of evidence-based medicine, psychologists have unique opportunity to contribute to the empirical basis of health care. When it comes to the psychological elements of adult patients, numerous studies show that they are more attentive and mindful of their malocclusion, which might lead to too positive expectations about the end effects of their therapy. Similar terms have been incorporated into cognitive behavioural psychotherapy, with a "first wave" referring to the initial behavioural therapy; a "second wave" referring to Albert Ellis' cognitive therapy; and a "third wave" referring to acceptance and commitment therapy, which emphasises one's pursuit of values, methods of self-awareness, acceptance, and psychological flexibility, rather than challenging negative thoughts. Orthodontists should be aware that dental materials and products have the potential to aggravate asthma. Dentifrices, fissure sealants, tooth enamel dust (during interproximal slicing), and methyl methacrylate are among these substances.
