Objective: The oral cavity forms an indispensable part of the human microbiome, for its unique and diverse microflora distributed within various niches. While majority of these organisms exhibit commensalism, shifts in bacterial community dynamics cause pathological changes within oral cavity and distant sites. The aim of this review was to appraise the current and emerging methods of detecting bacteria of the oral cavity paying particular attention to the cultivation independent methods. Design: Literature pertaining to cultivation based and cultivation independent methods of oral bacterial identification was reviewed. Methods: The specific advantages and disadvantages of cultivation based, microscopic, immunological and metagenomic identification methods were appraised. Results: Because of their fastidious and exacting growth requirements, cultivation based studies grossly underestimate the extent of bacterial diversity in these polymicrobial infections. Culture independent methods deemed more sensitive in identifying difficult to culture and novel bacterial species. Conclusion: Apart from characterizing potentially novel bacterial species, the nucleic acid sequence data analyzed using various bioinformatics protocols have revealed that there are in excess of 700 bacterial species inhabiting the mouth. Moreover, the latest pyrosequencing based methods have further broadened the extent of bacterial diversity in oral niches.

Self-Reported Gum Bleeding, Perception, Knowledge, and Behavior in Working-Age Hong Kong Chinese-A Cross-Sectional Study

Tsz Yung Wong, Yiu Cheung Tsang, Kim Wai Shadow Yeung, Wai Keung Leung

Summary: This cross-sectional study examined the association between oral symptoms of gum bleeding and behavioral factors, beliefs, and knowledge among Hong Kong Chinese. The study found that approximately half of the participants reported experiencing gum bleeding, with 62.2% experiencing it within the past 12 months. Higher education levels were associated with greater awareness of gum problems. Individuals with bleeding gums, particularly those with periodontitis, poor dental awareness/behaviors, and/or a poor lifestyle should be targeted for education and encouragement to improve their gum health.

Emerging strategies for environmental decontamination of the nosocomial fungal pathogen Candida auris

H. M. H. N. Bandara, L. P. Samaranayake

Summary: This article discusses the guidelines and ongoing research on environmental decontamination strategies for Candida auris, a multidrug-resistant fungal pathogen. The fungus's resistance to antifungal agents and ability to survive in healthcare settings make its eradication challenging. Current generic guidance lacks specific strategies for C. auris decontamination.

Obesity, Bone Loss, and Periodontitis: The Interlink

Pengfei Zhao, Aimin Xu, Wai Keung Leung

Summary: Obesity and periodontitis are common health concerns with negative relationships. Obesity leads to bone metabolic disorders and increased risks of periodontitis and alveolar bone loss. This review summarizes the clinical changes in periodontium and the biological interlinks in obesity-associated bone remodeling. The potential mechanism underlying obesity-enhanced alveolar bone loss is also discussed, providing practical considerations for managing periodontal disease in obese patients.

Probiotic Bifidobacteria in Managing Periodontal Disease: A Systematic Review

Victor Haruo Matsubara, Kausar Sadia Fakhruddin, Hien Ngo, Lakshman P. Samaranayake

Summary: This review examines the effect of bifidobacterial probiotics on periodontopathogens and host immune responses. The use of different strains of bifidobacteria was found to reduce periodontopathogens, decrease inflammation, and improve clinical parameters. However, further research is needed before the therapeutic use of bifidobacteria in periodontal infections.

Proteomic profile of in situ acquired pellicle on tooth and restorative material surfaces

Hongying Hu, Michael Francis Burrow, Wai Keung Leung

Summary: The proteomic profile of acquired pellicle on smooth bovine tooth and tooth-coloured restorative materials was evaluated and compared. It was found that significantly higher amounts of protein were adsorbed onto tooth surface. The protein quantity and composition of pellicles formed on different restorative material surfaces were similar, but distinct from the corresponding unstimulated whole saliva.

Validation of the Malay Oral Impacts on Daily Performances and Evaluation of Oral Health-Related Quality of Life in a Multi-Ethnic Urban Malaysian Population: A Cross-Sectional Study

Fei Yee Lim, Chui Ling Goo, Wai Keung Leung, Victor Goh

Summary: This study validates a newly translated Malay version of Oral Impacts on Daily Performances (OIDP-M) and compares oral health-related quality of life (OHRQoL), decayed, missing, or filled teeth (DMFT), and factors associated with OHRQoL among Malaysians. The results show differences in DMFT and OHRQoL between ethnicities.

Severe Periodontitis Is a Major Contributory Factor to Unmet Dental Healthcare Needs among Rheumatoid Arthritis Patients in Hong Kong

Mo Yin Mok, Wing Yin Kong, Katherine Chiu Man Leung, Mei Kuen Chow, Yi Lo, Claudia Pui Ling Tsang, Henry Kwok Kong Fung, Wallace Chak Sing Lau, Wai Keung Leung

Summary: This study found that patients with rheumatoid arthritis in Hong Kong commonly experience adverse oral and dental outcomes, including loose teeth and gum bleeding, with a higher risk of severe periodontitis compared to community counterparts, primarily attributed to plaque index.

Diagnostic application of intraoral ultrasonography to assess furcation involvement in mandibular first molars

Ray Tanaka, Katherine Lau, Andy W. K. Yeung, Wai Keung Leung, Takafumi Hayashi, Michael M. Bornstein, Maurizio S. Tonetti, George Pelekos

Summary: The study aimed to compare the accuracy of intraoral ultrasonography (USG) and conventional periodontal examinations in detection and classification of furcation involvement, and to compare it with cone beam computed tomography (CBCT). The results showed that intraoral USG had a similar performance to CBCT in diagnosing and classifying furcation involvement, without ionizing radiation.

Recrudescence of Scarlet Fever and Its Implications for Dental Professionals

Victor Haruo Matsubara, Janina Christoforou, Lakshman Samaranayake

Summary: There has been a significant increase in the incidence of scarlet fever, especially in Europe, after the COVID-19 pandemic. Scarlet fever is caused by streptococcus pyogenes, which produces pyrogenic exotoxin and is responsible for over 500,000 deaths annually worldwide. Superantigens secreted by this bacteria can overstimulate the immune system, leading to symptoms such as sore throat, high fever, and a sandpaper-like rash. Dental practitioners should be aware of the early symptoms for timely diagnosis, treatment, and referral.
