Teeth discoloration poses a widespread challenge in dental health across various regions. Conventional teeth whitening methods often result in enamel deterioration and soft tissue harm due to the utilization of incompatible whitening agents and continuous intense light exposure. Here, we propose an effective phototherapy technique for teeth whitening, employing pathways of energy transition through intersystem crossing. The integration of MoS nanosheets into carrageenan gel (MoS NSs@Carr) facilitates both photothermal-hyperthermia and the generation of reactive oxygen species (ROS) through photocatalytic processes. The efficacy of ROS generation by the phototherapeutic MoS NSs@Carr on teeth whitening in the scenario. This approach ensures comprehensive teeth whitening by eliminating deep-seated stains on the teeth while preserving structural integrity and avoiding any tissue toxicity. This research highlights the efficacy of the phototherapeutic MoS NSs@Carr for dental whitening and underscores the potential of exploring nanostructures based on MoS NSs for managing dental healthcare issue.

Effects of home bleaching agents on hybrid ceramics: mechanical properties and color change.
BMC Oral Health
January 2025
Department of Fixed Prosthodontics - Faculty of Dentistry, Ain Shams University, Organization of African Unity, St, El-Qobba Bridge, El Weili, Cairo Governorate, Egypt.
Background: Home bleaching is a promising option for addressing discolored teeth conservatively. However, its impact on the physical and mechanical properties of indirect restorations remains unknown. This study provides comparative insights into the material responses to aesthetic treatments by assessing the effects of home bleaching agents on two hybrid ceramics: VITA ENAMIC and Grandio Blocs.

Methods: A total of 120 healthy adults, with teeth shade A2 or darker, were randomly allocated to 3 groups (n = 40). All participants used 10% CP gel in a bleaching tray for 2, 4, and 8 hours daily for 14 days, with the option to extend treatment if they were dissatisfied.

Background: Bleaching is a conservative treatment option to deliver esthetic smile makeover for discoloured tooth. Various concentration of bleaching agents can influence the bonding of the restoration to the tooth.
Aims And Objectives: The aim of the study was to determine the effect of glutathione on bond strength of composite resin to enamel following extra coronal bleaching at two different time intervals.

Purpose: To evaluate the effect of aging and bleaching on the physico-mechanical properties of the different filled resin composites.
Methods: Samples of resin composites [Arabesk (A), G-aenial Anterior (G), i-LIGHT N (I) and Palfique Estelite Paste (P) \ were first divided into two subgroups. Thermal aging was applied to half of the samples.
The Impact of Pre-Treatment with Desensitizing Agents on the Effectiveness of In-Office Bleaching: An In Vitro Study.

In-office teeth bleaching is an esthetic dental procedure performed to whiten teeth. A desensitizing procedure often requires prior in-office bleaching to relieve tooth hypersensitivity. The objective of this study was to evaluate the bleaching efficiency of teeth specimens pre-treated with different desensitizing agents by analyzing the color parameters.
