Background: Despite the wide use of implants in dentistry, there is insufficient information about the ideal cement for retention.
Purpose: To determine the cement bond strength and marginal leakage of crown and partial denture cemented to implant abutments by four different types of cement.
Materials And Methods: Eighty-four direct abutments were divided into eight groups (n = 7). Fifty-six crown and bridge restorations were cemented using zinc phosphate (ZM), temporary cement (TM), resin-modified glass-ionomer cement (GM), and self-adhesive resin cement (RM). After cementation, thermal cycling and incubation in basic fuchsin dye was applied. The maximum load to failure, marginal leakage, and fracture modes were evaluated.
Results: The mean of retention strength for the bridges (874 N) was higher than the crown samples (705 N) (P = .005). The mean of retention strength for each cement group was ZM = 1298, RM = 1027, GM = 646, and TM = 187 N (P ≤ .0001). Marginal leakage was recorded in majority of the samples; the highest incidence was detected for ZM samples. The cement fracture was mostly adhesive in nature.
Conclusion: Self-adhesive resin and resin-modified glass ionomer cement had better mechanical properties to retain implant supported restorations.

Background And Aim: In this retrospective single center cohort study, we report the surgical outcomes of nephron-sparing surgery (NSS) for Wilms' tumor (WT) patients since centralization of pediatric oncology care in the Netherlands, and implementation of technological advancements. Therewith we describe the influence of experience and innovations for this type of surgery.
Methods: We retrospectively assessed all NSS procedures from January 1st 2015 until January 1st 2024 for patients who underwent surgery for a renal tumor at the Princess Máxima Center for Pediatric Oncology.

Aim: Natural orifice specimen extraction surgery (NOSES) has gained significant importance in treating cancers. The current study is a meta-analysis that aimed to assess the short-term efficacy and long-term prognostic impact of NOSES and conventional laparoscopic (CL) surgery in the treatment of colorectal cancer (CRC).
Method: Published reports in several medical databases up to February 2024 were searched and information pertinent to outcomes of NOSES and CL in retrospective and randomized studies to treat CRC was collected.

Background: Neuroendocrine liver metastases (NELM) significantly reduce survival in patients with neuroendocrine tumor. The management of NELM is challenged by a low rate of resectability and a high rate of recurrence. Indocyanine green (ICG) fluorescence imaging offers potential advantages in real-time tumor visualization and margin assessment.
