Study Type: Biographical/historical commentary (not original research)

Key Question: What was John Walford McLean's contribution to British dental materials research and how did his perspective shape restorative dentistry?

Key Findings:

• McLean contributed to major UK dental materials innovations (1943–1983), including reinforced dental porcelains, aluminous core porcelain (1965), polyacrylic acid-based cements, and glass-ionomer cements.
• Despite decades of innovation, McLean maintained in 1984 that gold and porcelain remained the only truly permanent restorative materials.
• In 1980 he predicted that future advances in aesthetic dentistry would depend on new technologies rather than material substitution—a view the author endorses as prescient.

Clinical Relevance: Understanding this history contextualises the evolution of materials still used in NHS restorative practice today, from glass-ionomers to modern resin composites. *(Limitations section omitted: this is a historical commentary, not a data-driven study.)*

Study Type: Commentary/case report (military exercise report, not original research with controlled data).

Key Question: Can a mobile, forward-deployed dental team reduce dental-related operational disruption during military exercises, and what transferable lessons exist for civilian mobile dentistry?

Key Findings:

• A repurposed dental support vehicle (DSV) enabled delivery of emergency, routine, and preventive care close to the front line during Exercise Immediate Response 24.
• This forward positioning reduced the need for casualty evacuations and minimised personnel downtime due to dental morbidity.
• Key operational lessons centred on power supply, vehicle mobility, and team versatility.

Clinical Relevance: Highlights principles applicable to UK dentists working in remote, austere, or resource-limited settings (e.g., outreach, disaster response, or humanitarian dentistry), relevant to NHS workforce planning for underserved areas.

Limitations: This is a descriptive account of a single exercise without comparative data, so effectiveness claims cannot be statistically verified.

Study Type: Case series

Key Question: What patterns and management challenges arise from traumatic dental injuries associated with e-bike or e-scooter use?

Key Findings:

• Three adult cases showed a spectrum of TDIs including concussion, enamel-dentine fractures, luxations, alveolar bone fractures and avulsions, often as combination injuries.
• Contributing factors identified included mechanism of trauma, alcohol intake and lack of helmet use.
• Cases highlighted delayed presentation and complex injury patterns often requiring multi-disciplinary dental management.

Clinical Relevance: With e-bike and e-scooter use rising across the UK, general dental practitioners are likely to be first point of contact for these often complex, multi-tissue injuries and should be prepared to assess and refer appropriately, including via NHS urgent dental care pathways.

Limitations: As a case series of only three patients, findings are descriptive and cannot establish incidence, risk factors, or generalisable treatment outcomes.

Study Type: Narrative review/commentary

Key Question: How should clinicians interpret oral microbiome research given inconsistencies in terminology and methodology, and what are the implications for clinical translation?

Key Findings:

• Terminology used across oral microbiome studies is inconsistent and often ambiguous, limiting comparability between studies.
• Current microbiome analyses cannot yet capture host immune response, functional gene expression, or strain-level virulence differences, all of which affect disease potential.
• Associations between microbial communities and oral/systemic disease are growing, but causation and clinical utility remain unproven.

Clinical Relevance: UK dental professionals should be cautious when interpreting commercial or research-based microbiome testing claims, as current evidence does not yet support their reliable use in diagnosis or treatment planning.

Limitations: As a narrative review, it does not systematically appraise evidence and offers no quantitative data or formal quality assessment.

Study Type: Commentary/perspective piece

Key Question: How can the UK dental profession better support the mental health and wellbeing of oral healthcare teams?

Key Findings:

• Proposes a tripartite support model: peer/practitioner support networks, dedicated support for those undergoing GDC referral, and crisis intervention services for severe mental health difficulties.
• Identifies GDC referral as a recognised major stressor requiring structured guidance and realistic outcome discussion.
• Recommends coordinating and building upon existing wellbeing initiatives rather than creating entirely new, disconnected schemes.

Clinical Relevance: With rising stress and regulatory pressures reported across UK dental teams, this piece offers a practical framework practices and professional bodies could adopt to strengthen staff wellbeing and retention. *(No limitations section included, as this is a perspective/commentary rather than original research.)*

Study Type: Qualitative study (semi-structured interviews, framework analysis)

Key Question: What role can oral health professionals play in reducing sugar-sweetened beverage (SSB) consumption among children and young people?

Key Findings:

• 38 interviews (18 CYP aged 11–16, 9 caregivers, 11 OHPs) identified four themes: OHPs' knowledge of SSB types, influences/consequences of SSB use, OHPs' supportive role, and challenges of adolescent behaviour change.
• Taste, peer influence, and social media were key drivers of SSB consumption in CYP.
• OHPs reported barriers including peer pressure, adolescent autonomy, and limited consultation time.

Clinical Relevance: With SSB consumption linked to caries risk and oral health inequalities, UK dental teams—including those delivering NHS paediatric care—are well-positioned to deliver targeted, adolescent-appropriate dietary advice despite time pressures.

Limitations: Findings are based on self-reported perceptions from a relatively small, qualitative sample, limiting generalisability to wider practice settings.

Study Type: Cross-sectional study

Key Question: Do anxious and non-anxious children differ in visual attention to dental clinic stimuli, and can visual distractors redirect gaze away from anxiety-provoking items?

Key Findings:

• 49.6% of 121 children (aged 6–12) were anxious; they fixated faster and dwelled longer on instruments/handpieces than non-anxious peers (p<0.001).
• Adding visual distractors significantly shifted gaze toward child-friendly elements, changed fixation order, and reduced revisits to clinical tools.
• Both groups focused heavily on clinicians' eyes, with decorated masks drawing extra attention.

Clinical Relevance: Findings can guide UK paediatric dental teams and practice design (e.g., surgery decor, decorated masks) to reduce anxiety-driven focus on instruments, potentially improving cooperation and reducing avoidance in NHS paediatric services.

Limitations: Gaze behaviour was assessed using static images rather than real clinical settings, limiting ecological validity.

Study Type: Cross-sectional observational study

Key Question: At what age and with what gender differences does the midpalatal suture (MPS) mature, and can this guide the need for CBCT before maxillary expansion?

Key Findings:

• Optimal age threshold distinguishing early (A–C) from late (D) MPS stages was 11.2 years overall (males 11.2 years; females 10.75 years), with strong sensitivity/specificity.
• Age strongly correlated with MPS stage (p<2.2e-16); females matured earlier than males, particularly aged 0–20 years (p<0.05).
• Stage D2 showed a distinct age distribution from both D1 and E (p<0.05), supporting its retention as a separate stage.

Clinical Relevance: For UK clinicians planning maxillary expansion (e.g., RME/SARME), these age thresholds help judge when CBCT assessment of suture maturation is truly necessary, reducing unnecessary radiation exposure especially in younger children, in line with ALARA principles under IR(ME)R regulations.

Limitations: Cross-sectional design cannot confirm individual maturation trajectories over time, limiting causal interpretation of age-related changes.
