Cementation of a polyethylene liner into the well-fixed shell is a convenient option for revision total hip arthroplasty. We retrospectively reviewed 45 patients who had liner cementation to investigate the risk factors which gave rise to major complications and reoperation. Patients were observed for a minimum of 7 years (range 7.8-14 years). Relevant risk factors (age, BMI, surgical approach, previous cup size and position, types of coated surface) were assessed with Cox regression analysis. The mean Harris Hip Score was improved from 62.5 (range 57-68) preoperatively to 87.1 (range 70-97). A total of 7 hips (15.5%) had acetabular component loosening that was treated with reoperation. Prevalence of acetabular component loosening was statistically significantly higher in hydroxyapatite-coated group (5 of 13) than in the Ti-coated group (2 of 32, p = 0.015). All recurrent dislocations occurred in patients treated with a posterior approach. Diameter of the previous metal shell of below 54 mm showed a lower 10-year survival rate than those greater than 54 mm in diameter. PE liner cementation in stable metal cup is a useful alternative option for carefully selected patients. Pre-existing HA-coated cups as well as small sized cups were indicative of poor outcomes.

Total hip arthroplasty (THA) is a highly effective surgical intervention for end-stage hip joint disorders. While common complications such as infection, dislocation, and prosthetic loosening are well-documented, rarer complications remain underreported. One such complication is foreign body interposition on the bearing surface, which can compromise joint mechanics and adversely affect outcomes.

The World Health Organization (WHO) has added glass ionomer cement (GIC) to the WHO Model List of Essential Medicines since 2021, which represents the most efficacious, safe and cost-effective medicines for priority conditions. With the potential increase in the use of GIC, this review aims to provide an overview of the clinical application of GIC with updated evidence in restorative and preventive dentistry. GIC is a versatile dental material that has a wide range of clinical applications, particularly in restorative and preventive dentistry.

Objectives: The aims of this systematic review were to estimate the success rates of root caries restorations, and to identify possible factors associated with the success of root caries restorations.
Data And Sources: Literature search was conducted in three databases, PubMed, MEDLINE and Web of Science to identify clinical studies reporting on the success of restorative treatment for root caries. Factors that may influence clinical outcomes of the restorative treatment were summarized and analyzed.
Evaluation of Microleakage and Shear Bond Strength of Two Different Calcium-based Silicate Indirect Pulp Capping Agents When Restored with Glass Ionomer Cement and Composite Resin Restoration: A Comparative Study.
Int J Clin Pediatr Dent
September 2024
Department of Pediatric and Preventive Dentistry, Karnavati School of Dentistry, Karnavati University, Gandhinagar, Gujarat, India.
Background: Indirect pulp therapy (IPT) is a conservative treatment approach that leaves the deepest caries adjacent to the pulp undisturbed in an effort to avoid pulp exposure. The result of IPT is primarily dependent on the biocompatibility, sealing capacity, adaptability of the overlying restoration to underlying dentin, and strength of the liner material utilized.
Aim: To evaluate shear bond strength (SBS) and microleakage of mineral trioxide aggregate (e-MTA) and biodentine when restored with glass ionomer cement (GIC) and composite resin after their initial set time.
