The effect of a barrier membrane on the incorporation of deproteinized bovine bone mineral (DBBM) in experimental defects at the time of early implant placement. A preclinical study.

Objectives: This study aimed to assess membrane use with a bone substitute graft for guided bone regeneration (GBR) in experimental dehiscence defects.

Materials And Methods: Maxillary second incisors (I2) in 9 dogs were extracted. Six weeks later, implants were inserted and experimental dehiscence defects (5 × 3 mm) created on the buccal aspect.

controls kidney resident macrophage heterogeneity.

Kidney macrophages are comprised of both monocyte-derived and tissue resident populations; however, the heterogeneity of kidney macrophages and factors that regulate their heterogeneity are poorly understood. Herein, we performed single cell RNA sequencing (scRNAseq), fate mapping, and parabiosis to define the cellular heterogeneity of kidney macrophages in healthy mice. Our data indicate that healthy mouse kidneys contain four major subsets of monocytes and two major subsets of kidney resident macrophages (KRM) including a population with enriched expression, suggesting monocyte origin.

Inter-implant distance and buccal bone thickness for a novel implant design: a preclinical study.

Objectives: This study assessed bone height between novel tapered implants at different inter-implant thread peak (TP) distances, and the impact of TP distance from outer buccal bone (BB) on marginal bone levels (MBL).

Materials And Methods: Fully tapered implants with 0.5-mm thread depth and TP diameter 1 mm wider than the shoulder diameter were placed in healed ridges of minipigs.

Referral Compliance Following a Diabetes Screening in a Dental Setting: A Scoping Review.

With type 2 diabetes prevalence increasing in Australia, and the condition associated with significant morbidity and mortality, screening for dysglycaemia in the dental setting has been proposed to identify asymptomatic individuals. Screening commences with a risk assessment, and individuals identified at elevated risk for having diabetes are then referred to their medical practitioner for confirmation of their glycemic status. Therefore, for screening to be effective, individuals need to adhere to their oral health professionals' (OHP) advice and attend their medical follow-ups.

Risk factors for periodontitis & peri-implantitis.

Risk is part of all health professions and generally indicates the chance of getting some form of illness. For dental practitioners this includes periodontitis or peri-implantitis, the focus of this issue. Many risk factors are involved in the development of disease and most likely interact or overlap.

Mental health and periodontal and peri-implant diseases.

Mental health disorders, particularly depression and anxiety, affect a significant number of the global population. Several pathophysiological pathways for these disorders have been identified, including the hypothalamic-pituitary-adrenal axis, autonomic nervous system, and the immune system. In addition, life events, environmental factors, and lifestyle affect the onset, progression, and recurrence of mental health disorders.

Diabetes and Oral Health (DiabOH): The Perspectives of Primary Healthcare Providers in the Management of Diabetes and Periodontitis in China and Comparison with Those in Australia.

Diabetes and periodontal disease are highly prevalent conditions around the world with a bilateral causative relationship. Research suggests that interprofessional collaboration can improve care delivery and treatment outcomes. However, there continues to be little interprofessional management of these diseases.

Self-Assembled Peptide Habitats to Model Tumor Metastasis.

Metastatic tumours are complex ecosystems; a community of multiple cell types, including cancerous cells, fibroblasts, and immune cells that exist within a supportive and specific microenvironment. The interplay of these cells, together with tissue specific chemical, structural and temporal signals within a three-dimensional (3D) habitat, direct tumour cell behavior, a subtlety that can be easily lost in 2D tissue culture. Here, we investigate a significantly improved tool, consisting of a novel matrix of functionally programmed peptide sequences, self-assembled into a scaffold to enable the growth and the migration of multicellular lung tumour spheroids, as proof-of-concept.

Microbiome profiles of non-responding and responding paired periodontitis sites within the same participants following non-surgical treatment.

Aim: Periodontitis is a site-specific, chronic disease treated by non-surgical debridement of subgingival plaque. We aimed to determine the microbiome of sites that did not respond to this treatment (NR) compared with paired good responding (GR) sites before and after treatment.

Materials And Methods: In a longitudinal cohort study, clinical parameters of disease and biological samples were taken prior to and 3 months after treatment.

Knowledge and attitudes towards periodontal health among Australians diagnosed with diabetes.

Diabetes and periodontitis are two major diseases affecting the Australian population. Despite the established interrelationship between the diseases, the knowledge of people with diabetes about this interrelationship is limited. This study investigated the knowledge of individuals with diabetes towards periodontal health in Australia.

The effectiveness of using the perioscope as an adjunct to non-surgical periodontal therapy: Clinical and radiographic results.

Background: It is well known that following root surface debridement (RSD) residual deposits remain. Periodontal endoscopy has provided a method of directly visualizing root surfaces during periodontal debridement in an intact pocket without the need for surgical incision. The aim of this study was to determine if periodontal debridement using endoscopic visualization was more effective in improving clinical and radiographic parameters as compared to RSD.

Early implant placement in ridge preserved extraction sockets: A pre-clinical in vivo study.

Objectives: The aim was to analyse the outcomes of early implant placement after 6 and 12 weeks of healing in ridge preserved sites in a canine model.

Materials And Methods: Implants were placed in second maxillary incisors sites in 9 dogs 6 weeks after grafting of the sockets with 90% deproteinized bovine bone mineral in 10% collagen matrix (DBBMC) and closure with resorbable type I/III porcine collagen matrix (PCM). The implants were randomly assigned to 6 (T6) and 12 (T12) weeks of healing.

Dental Implant Hygiene and Maintenance Protocols: A survey of oral health practitioners in Australia.

Dental implant care and maintenance is of critical importance as implants grow in popularity as a tooth replacement option. The purpose of this study was to investigate the implant-related training and clinical practices of oral health practitioners (OHPs) in Australia regarding oral hygiene instructions (OHI) and maintenance protocols, and to better understand their role in providing peri-implant services. A 42-item web-based survey was forwarded to the members of the Dental Hygienists Association of Australia and the Australian Dental and Oral Health Therapists' Association.

"Say Ahhh": Experience and Views on Halitosis Management in the General Public in Victoria, Australia.

Introduction: Halitosis is common and can have a significant impact on quality of life. It is attributed to both intraoral and extraoral causes. Although halitosis treatment depends on the aetiology, little is known about consumers' perception of halitosis causes and the types of assistance sought.

Dentists' preferences in implant maintenance and hygiene instruction.

Background: This study investigated the preferences of dentists in Australia in providing professional implant maintenance and implant-specific oral hygiene instructions (OHI).

Methods: General dentists were surveyed online about their preferences in peri-implant diagnostics, maintenance provision, armamentarium used, and implant OHI techniques and frequency.

Results: Most of the 303 respondents (96%) provided maintenance services; 87.
