RESUMO
Background: Caregivers play an important role in informal patient management. Identification of the support types and the financial challenges faced by caregivers will provide information on strategies to ease this burden. This study aimed to describe the support types and financial burden amongst caregivers in a tertiary hospital in North Central Nigeria. Methods: This was a cross-sectional study conducted amongst caregivers of inpatients in a tertiary hospital in North Central Nigeria. Data were collected using a pre-tested interviewer-administered questionnaire and were analysed using the Statistical Package for the Social Sciences package version 23. Results were reported in frequencies and proportions and presented in prose, tables and charts. Results: A total of 400 caregivers were recruited. The mean age was 38.32 ± 12.82 years and most (66.0%) were females. Caregivers supported their patients by running errands (96.3%) and 85.3% reported caregiving as stressful. The reported errands were purchase of medications (92.3%), supply of non-medical needs (63.3%), submission of laboratory samples and collection of results (52.3%) and service payment (47.5%). About two-thirds (63.2%) reported loss of income while caregiving and about half (50.8%) provided financial support to the patients. Conclusion: This study suggests that majority of caregivers experience significant physical and financial burden while caregiving. This burden can be eased off by the simplification of payment and laboratory processes and employment of more staff to support patients admitted to the wards. The financial burden experienced by caregivers reinforces the need to encourage more Nigerians to enrol in a health insurance scheme.

OBJECTIVES: In vitro investigation of the effects of fixed dental prosthesis (FDP) support and loading conditions on the fracture behavior of all-ceramic, zirconia-based FDP veneered with computer-aided design/computer-aided manufacturing (CAD/CAM)-manufactured lithium disilicate ceramic. MATERIALS AND METHODS: Based on a model for a 3-unit FDP in the molar region (tooth in region 15, implant in region 17), 16 identical zirconia frameworks were fabricated and veneered with milled lithium disilicate ceramic. Another 16 FDPs were manufactured similarly, using a model in which the tooth was replaced by an implant. The specimens underwent 10,000 thermal cycles between 6.5 and 60 °C and 1,200,000 chewing cycles with a force magnitude of 100 N. All were then subsequently loaded until fracture in a universal testing device. Half of the FDPs were subjected to centric and axial loading on the pontic, the others to eccentric and oblique loading on one cusp of the pontic. RESULTS: No failures were observed after artificial aging. Fracture loads of tooth-implant-supported restorations were 1636 ± 158 and 1086 ± 156 N for axial and oblique loading, respectively; implant-supported FDPs fractured at 1789 ± 202 and 1200 ± 68 N, respectively. Differences were significant for load application (P < 0.001) and support type (P = 0.020). For the two types of load application, fracture mode differed substantially: complete fracture was observed for centric and axial loading whereas mixed cohesive/adhesive failure was observed for many FDPs loaded eccentrically and obliquely. CONCLUSIONS: The high incidence of chipping of manually veneered implant-supported all-ceramics restorations might be reduced by use of CAD/CAM-manufactured lithium disilicate veneers. CLINICAL RELEVANCE: FDPs veneered with lithium disilicate resist occlusal forces of 500 N, irrespective of load application and support type. The fracture resistance of implant-supported FDPs was, however, higher than that of combined tooth-implant-supported FDPs. Their clinical use seems to be justified.
