Objective: The aim of our study was to analyze the hearing results of ossicular chain reconstruction in incus long process defects in pediatric patients.
Methods: This retrospective study included 15 pediatric patients that had incus long process defect due to chronic otitis media or adhesive otitis, and repaired with glass ionomer cement between 2009 and 2015. The audiological tests (air conduction thresholds, bone conduction thresholds, air bone gap) obtained preoperatively and one year after surgery were compared. In addition, preoperative and postoperative air bone gap differences were estimated to determine hearing gain.
Results: Mean air conduction and air bone gaps decreased significantly one year after surgery when compared to the preoperative values (p< 0.001 for both). Mean hearing gain was 20.33±6.36dB one year after surgery.
Conclusion: Use of glass ionomer cement to repair incus long process defects is a suitable method that improves hearing in pediatric patients. Further large studies that compare glass ionomer cement ossiculoplasty with other ossicular reconstruction methods are needed.

Impact of surface conditioner phytic acid (IP6) Er,Cr:YSGG laser (ECYL) methylene blue photodynamic therapy (MB-PDT) on the microleakage and shear bond strength (SBS) of resin-modified glass ionomer cement (RMGIC) to primary sound dentin. Overall, 80 extracted sound primary molars were collected followed by their submergence in self-cure acrylic resin. The dentin surface was exposed and made flat and was assigned into four groups based on the surface conditioning.

Objective: To investigate the effect of cervical margin relocation with four different injectable restorative materials on the fracture resistance of molars receiving mesio-occluso-distal CAD/CAM nanoceramic onlay restorations.
Materials And Methods: One hundred and five sound mandibular molars received a standardized mesio-occluso-distal onlay preparation, with cervical margins located 2 mm apical to the cemento-enamel junction. The molars were randomly allocated into five groups (n = 21) according to the cervical relocating materials used: Group I had no cervical margin relocation; Group II used a highly viscous glass ionomer; Group III used a highly-filled injectable resin composite; Group IV used a resin-modified glass ionomer; and Group V used a bioactive ionic resin.

Background: The aim was to evaluate the stresses in teeth, with external root resorption (ERR) restored with different materials using finite element analysis (FEA).
Methods: In this study, a Micro-CT scan was conducted on a prepared maxillary central tooth. DICOM-compatible images obtained from the sections were converted into stereolithography format using Ctan software.

Polydopamine (PD), inspired by the wet adhesion mechanism of mussel foot proteins, has emerged as a promising adhesive material with wide-ranging applications. This study aimed to compare the adhesive properties of PD and Glass Ionomer Cement (GIC) on enamel and dentin substrates, evaluating PD's potential as an alternative adhesive in dental practice. A total of 120 human premolars were prepared, with 80 teeth allocated for Scanning Electron Microscopy (SEM) analysis and 40 teeth reserved for shear bond strength testing.

Aim: This prospective clinical study aimed to clinically investigate the efficiency of (GIC) glass-ionomer cement application (Ionostar Plus + Easy Glaze, VOCO) in reducing hypersensitivity in permanent molars affected by molar incisor hypomineralisation when assessed immediately (15 min) and 12 weeks after its application.
Materials And Methods: Children with at least one hypersensitive MIH-affected permanent molar (MIH-TNI-3 or 4). The pre-treatment status was evaluated and only included if they did not receive a tooth-specific in-office desensitizing treatment within one month.
