Prevalence of dentine hypersensitivity, erosive tooth wear, gingival recession and periodontal health in seven European countries.

Objectives: To determine the prevalence and associated risk indicators for dentine hypersensitivity (DH), erosive tooth wear (ETW), gingival recession (GR), and gingival inflammation (bleeding on probing, BOP), with clinical and questionnaire data from seven European countries.

Methods: A cross-sectional, observational, seven-European country, epidemiological study in systemically healthy adults. Participants completed a questionnaire regarding oral hygiene, diet and lifestyle factors.

Mind the gap-What is the appropriate time interval between sequential dentine stimuli to elicit a dentine hypersensitivity pain response in clinical studies?

Objectives: To determine the time interval required for a tooth diagnosed with DH to recover from a stimulus (cold air-blast/tactile) and respond with a similar elicited pain response to a repeat stimulus.

Methods: A single-centre, non-randomised, clinical study in healthy adult volunteers. Eligible participants with ≥1 tooth with either a qualifying Schiff score ≥2 following cold air-blast or tactile Yeaple score of ≤20 g were allocated to tactile or air-blast group.

Ego4D: Around the World in 3,000 Hours of Egocentric Video.

We introduce Ego4D, a massive-scale egocentric video dataset and benchmark suite. It offers 3,670 hours of daily-life activity video spanning hundreds of scenarios (household, outdoor, workplace, leisure, etc.) captured by 931 unique camera wearers from 74 worldwide locations and 9 different countries.

A randomised controlled trial to evaluate the effectiveness of personalised oral hygiene advice delivered via video technology.

Objectives: To determine whether video-technology oral hygiene advice (OHA) improved clinical plaque and bleeding on probing (BOP) scores in individuals diagnosed with gingivitis, compared to conventional OHA after 3-months.

Methods: This parallel, randomised 2-arm treatment, single-centre study, assessed Turesky Plaque Index (TPI) and BOP at baseline and 3-months in adult participants with mild-moderate gingivitis. Eligible participants with smartphones were randomised at baseline to intervention (tailored video OHA), or control (conventional OHA).
