Enhanced antibacterial activity and superior biocompatibility of cobalt-deposited titanium discs for possible use in implant dentistry

The clinical success of implants depends on rapid osseointegration, and new materials are being developed considering the increasing demand. Considering cobalt (Co) antibacterial characteristics, we developed Co-deposited titanium (Ti) using direct current (DC) sputtering and investigated it as a new material for implant dentistry. The material was characterized using atomic absorption spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. The material's surface topography, roughness, surface wettability, and hardness were also analyzed. The Co thin film (Ti-Co15) showed excellent antibacterial effects against microbes implicated in peri-implantitis. Furthermore, Ti-Co15 was compatible and favored the attachment and spreading of MG-63 cells. The alkaline phosphatase and calcium mineralization activities of MG-63 cells cultured on Ti-Co15 remained unaltered compared to Ti. These data correlated well with the time-dependent expression of ALP, RUNX-2, and BMP-2 genes involved in osteogenesis. The results demonstrate that Co-deposited Ti could be a promising material in implant dentistry.

Exploring experiences of living with removable dentures-A scoping review of qualitative literature

OBJECTIVE

Examine the literature on the experiences of living with removable dentures (complete or partial) to identify any gaps and provide a map for future research.

BACKGROUND

Increasing proportions of society are living partially dentate with some form of restoration, including removable dentures. Previous studies have reported on the location, materials and usage of these prostheses, along with effects on oral-health-related quality of life (OHRQoL). However, less is known about experiences with removable dentures from a patient-centred perspective.

METHODS

A scoping review of the qualitative literature was undertaken using the framework of Arksey and O'Malley, updated by Levac et al. Literature searches were carried out using Medline and Web of Science. Papers were screened by title and abstract using inclusion and exclusion criteria. Remaining papers were read in full and excluded if they did not meet the required criteria. Nine papers were included in the final review.

FINDINGS

Key themes from these papers were: impact of tooth loss and living without teeth, and its impacts in relation to social position, appearance, confidence and function (chewing and speaking); social norms and tooth loss, including attitudes to tooth retention and treatment costs, and changes in intergenerational norms towards dentures; expectations of treatment, including patients being more involved in decision making, viewing the denture as a "gift" and dentures helping to achieve "an ideal"; living with a removable denture (complete or partial), including patient preparedness for a denture, adaptation and impacts on activities and participation; and the dentist-patient relationship, including issues with information and communication, and differing priorities between patients and dentists.

CONCLUSION

Little qualitative research exists on experiences of living with a removable denture. Existing literature demonstrates the importance of dispersed activities in differing social, spatial and temporal contexts when wearing removable dentures. Focusing on processes of positive adaptation to dentures and OHRQoL, rather than deficits, is also required to fully understand patients' experiences. Additionally, more complex technological advances may not always be in the best interest of every patient.

Perception of Edentulous Patients and Dental Professionals towards Care and Maintenance of Complete Denture Prostheses

Methods

A descriptive qualitative study was conducted among 30 EDPs attending dental prosthetic clinics (DPCs) at the four centres in Fiji and 28 DPs at the four DPCs under purposive sampling. Semi-structured questionnaire with open-ended questions was used for in-depth interview (IDI) with EDPs via telephone and focus group discussion (FGD) with DPs virtually via Zoom. Participant responses were recorded and thematic analysis was used to manually analyze the verbatim transcripts.

Results

Five themes were identified as perceptions of EDPs towards care and maintenance of CDP in Fiji: patient perceptions towards CDP, CDP care and maintenance, communication between DPs and EDPs, challenges faced in CDP, and management strategies to CDP care and maintenance. Seven themes were identified as perceptions of DPs: CDP guidelines, post-denture insertion advice, care and maintenance, challenges while treating EDPs, management strategies to challenges faced, communication and teamwork, and recommendations to improving quality of CDP delivery in Fiji.

Conclusion

Patients' perception towards care and maintenance of CDP was low. It is highly recommended for EDPs to adhere to CDP advice given by DPs whilst for DPs, it had been recommended to provide written, oral, and visual forms of CDP care and maintenance advice to EDPs for effectiveness.

Challenges faced by edentulous patients (EDPs) during complete denture prostheses (CDP) service delivery in Fiji - a qualitative study

BACKGROUND

Edentulism is a state of having no teeth in the oral cavity, an irreversible condition popularly known as the marker of disease burden on the oral health. For edentulous patients (EDPs) Complete Denture Prostheses (CDP) is a means to improve oral health. Due to limited studies in this area, this research aimed to explore the challenges faced by the EDPs during CDP service delivery in Fiji.

METHODS

A directed descriptive qualitative study was conducted among EDPs attending Dental Prosthetic Clinics (DPCs) at the four centres in Fiji under purposive sampling. A semi-structured questionnaire with open ended questions was used for in-depth interview with EDPs who had worn CDP for 1 year via telephone. Participant responses were recorded, transcribed verbatim and analyzed manually using thematic analysis.

RESULTS

A total of 30 EDPs participated in the study. Six themes were identified as challenges faced by the EDPs during CDP service delivery in Fiji: lack of information, non-compliance, overwhelmed by illness, reduction on quality of life (QoL) financial barriers to CDP treatment care and personal acceptance. 77% of EDPs felt they did not receive adequate information on CDP when attending DPCs which indicated the non-compliance nature irrespective of using and cleaning CDP on a daily basis. The Dental Professionals (DPs) at the DPCs gave their full support in attending to the CDP challenges faced by the EDPs in Fiji during the review clinics.

CONCLUSION

The EDPs expressed a variety of challenges that was faced while seeking appropriate CDP services in Fiji. The findings demonstrate the need to explore approaches to develop patients' engagement practices during CDP service delivery by the Dental professionals (DPs), which leads to effective oral health promotion in Fiji for CDP wearers.

BDJ Open 2021 - our most successful year to date

This paper aims to provide an update on the previous version published towards the end of last year, titled 'BDJ Open (2019-2020) and the advantages of open access publishing'. In this paper, we will highlight articles published throughout 2021, in order to focus on which areas authors felt were important to publish open access and also which areas have been expanded upon in the journal. Furthermore, this paper will examine how open access publishing in BDJ Open has enabled the continuous process of hypothesis testing to be shared more widely, as well as how publishing protocols and early results open access gives strength to that by allowing earlier opportunity for comment by other researchers, both through the peer review process and through further correspondence to authors directly and to the journal editors who publish their work.
