Purpose: This study aimed to determine whether gender, age, and initial tooth hue impacted the effect of laser tooth whitening.
Materials And Methods: Ninety-one subjects were enrolled in a laser tooth whitening study at Kaohsiung Medical University. Sensitivity was evaluated by asking the patients about any tooth sensitivity they experienced after the whitening procedures were performed. The LaserSmile tooth whitener, containing 35% hydrogen peroxide, was applied to the tooth surfaces of both arches from the central incisor to the second premolar, and the LaserSmile Twilite diode laser was applied to the same maxillary and mandibular teeth. After removal of the whitening gel, shade matching was immediately performed with the ShadeEye NCC Dental Chroma Meter. Patients were classified into the following groups: tetracycline stain, gender, age, and initial tooth hue. Only 5 of the 91 individuals had tetracycline staining.
Results: The initial tooth shade and the amount of shade change showed no significant differences between female and male patients, but a significant difference was found between hue and age group.
Conclusions: Teeth with hue A showed greater shade improvement than teeth with hue C and hue D. Whitening response was better in younger individuals, and gender was not a factor that affected the whitening response. Sensitivity is common during the whitening procedure but can be tolerated by the patients.

Objective: Understanding the sealing ability of restorative materials to prevent microleakage and its consequent complications-such as secondary caries, postoperative sensitivity, and restoration failure-is imperative in clinical dentistry. This study aims to compare the microleakage performance of four restorative materials-bioactive composite resin (Activa Pronto), alkasite restorative (Cention N), compomer (Dyract Flow), and glass ionomer cement (Type 2 GIC)-in Class V cavities of extracted premolar teeth.
Materials And Methods: Forty non-carious, intact premolar teeth were selected and prepared with standardized Class V cavities.
Neodymium-Doped Yttrium Aluminum Perovskite (Nd:YAP) Laser in the Elimination of Endodontic Nickel-Titanium Files Fractured in Rooted Canals (Part 2: Teeth With Significant Root Curvature).

Background In root canal treatment, fracture of nickel-titanium (Ni-Ti) instruments poses a significant challenge, particularly in teeth with complex anatomy, such as those with pronounced root curvature. A standardized and universally accepted method to address this complication remains elusive. The current study aims to assess the efficacy of neodymium-doped yttrium aluminum perovskite (Nd:YAP) laser-assisted approach in managing fractured Ni-Ti files in teeth with significant root curvature (>15 degrees).

Aim: This in vitro study investigated the effects of incorporating 1%, 3%, and 5% calcium oxalate into 15% hydrogen peroxide (HO), with and without laser activation, on the whitening of teeth discolored by mineral trioxide aggregate (MTA).
Methods: The pulp tissue of 80 bovine incisors was removed, and an MTA plug was placed at 2 mm below the cementoenamel junction. After nine months, the samples were randomly divided into eight groups (n = 10).

Background: To evaluate the effect of 4 final irrigation solutions at different temperatures on dentin tubule penetration of bioceramic-based sealer using the warm vertical compaction method with a laser scanning confocal microscope (CLSM).
Methods: In total, 180 human maxillary incisors were prepared. Different final irrigation solutions [distilled water, ethylenediaminetetraacetic acid (EDTA), peracetic acid, or 1-hydroxyethylidene-1,1-bisphosphonate (HEBP)] at various temperatures (25, 36, or 60˚C) were used.
