The evolution of restorative materials in prosthodontics has led to the emergence of indirect composite resins, including ceromers, as alternatives to traditional metal-ceramic restorations. However, research gaps exist regarding the impact of ageing protocols on the bond strength of ceromer composites to different metal substructures, necessitating further investigation in this area. ⋯ Applying the ageing protocols, the type of substructure material had no significant effect on the SBS of the ceromer indirect composite except for tea immersion.

Dental implant-supported prostheses have been scientifically accepted and have been a common treatment choice in the case reconstructing of partial or total tooth loss. In additon, bone grafts (alloplast, xsenograft, allograft) are frequently used in implant and sinus lift surgical procedures. ⋯ As a result of this study, it can be thought that different graft materials can be successfully used in peri-implant-guided bone regeneration and may be an alternative to autogenous grafts.

Randomized Controlled Trial
A Comparison of the Efficacy and Safety of Mifepristone and Misoprostol Versus Misoprostol alone for Induction of Labour in Nigerian Women with Intrauterine Fetal Death: A Triple Blind Randomized Controlled Trial.
Intrauterine foetal death (IUFD) is an unpleasant pregnancy outcome and prompt delivery of the dead foetus is usually desired by mothers. Unfortunately, spontaneous labour and delivery may not occur early and prolonged retention of the dead foetus in utero is life-threatening. Many of the agents currently used for the induction of labour may result in a prolonged delivery process. ⋯ The combination of mifepristone and misoprostol has greater efficacy and better safety profile than the use of misoprostol alone for induction of labour. This combination should be considered when induction of labour is indicated for IUFD.

Vaginal bleeding is the most common cause of presentation at the emergency department in the first trimester. Clinical presentation helps determine the likely cause of first-trimester vaginal bleeding. However, ultrasound imaging is required to reach a definitive diagnosis. ⋯ Clinical assessment is insufficient in the identification of the cause of vaginal bleeding due to the overall low concordance rate. A combination of clinical assessment and ultrasonography is required for decision-making in every case.

In the past five years, observational evidence suggests that the rates and determinants of preterm birth may have changed due to the effect of the coronavirus disease 2019 (COVID-19) pandemic and other humanitarian crises in our environment. ⋯ The incidence of preterm birth is high in Enugu, and associated factors were advanced maternal age, low socioeconomic status, and a history of miscarriage.
