Comparison of different head and neck positions and behaviour in ridden elite dressage horses between warm-up and competition

Summary Head and neck position (HNP) has been identified in literature as important influence on wellbeing. It was investigated in ridden elite dressage horses whether there is a relation between the HNP, ethological indicators and the grading in the warm-up area and in the test. 49 starters (83%) of a Grand-Prix Special (CDIO5 *) as part of the CHIO in Aachen 2018 and 2019 were examined. For each horse-rider pair, HNP (angle at vertical (AT), poll angle (PA), neck angel (NA)) used were analysed as well as conflict behavior for 3 minutes each in warm-up area and test. 6571 individual frames were used. The noseline was carried significantly less behind the vertical in test vs. warm-up (5.43 ° ± 4.19 vs. 11.01 ° ± 4.54 behind the vertical; T = 34.0; p < 0.05). The horses showed significantly less conflict behavior in the test vs. warm-up (123 ± 54 vs. 160 ± 75) (T = 76.00; p < 0.01). In the latter, a smaller PA and more defensive behaviour of the horses was observed compared to the test. A correlation between the grading of test and HNP was found (R = 0.38; p < 0.05). The further the noseline was behind the vertical, the higher was the chance of a good rating. The higher riders were ranked in the “FEI world ranking”, the higher were their marks in the competition (2018: r = -0.69, p < 0.05; 2019: r = -0.76, p < 0.05). Horses of riders higher in world ranking tended to show more unusual oral behaviour (r = -0.30, p < 0.05), and a noseline stronger behind the vertical (r = -0.37, p < 0.05) resulting in a smaller NA (r = 0.43, p < 0.05). This are from the point of view of animal welfare problematic results.

Comparison of periodontal parameters between patients with ischemic and dilative cardiomyopathy

Background This cross-sectional study aimed in the comparison of periodontal parameters, number of remaining teeth and oral behaviour between patients with ischemic- (ICM) and non-ischemic dilative cardiomyopathy (DCM). Methods Patients with HF from the Department for Cardiac Surgery at the Heart Center Leipzig were included. The two groups (ICM and DCM) were composed by matching according to age, gender and smoking habits. All participants received a comprehensive periodontal examination, including a periodontal probing on six measurement points of each tooth. Results A total of 226 patients (n = 113 each group) was included. Patients in DCM group used interdental cleaning significantly more often than ICM (23.9% vs. 12.5%, p = 0.04). The majority of patients in both groups (ICM: 83.6%, DCM: 84.6%, p = 0.23) were diagnosed with stage III–IV periodontitis. Periodontal parameters were comparable between groups (p > 0.05). Variance analysis revealed no influence of the group (ICM vs. DCM) on the number of remaining teeth (p = 0.16), periodontitis stage (p = 0.27) or the periodontal inflamed surface area (p = 0.62). Conclusions Patients with severe HF show high periodontal burden, without any differences between ICM and DCM group. Therefore, increased attention should be payed to periodontal health of patients with severe heart disease, irrespective of their underlying disease.

The impact of Covid-19-related distress on general health, oral behaviour, psychosocial features, disability and pain intensity in a cohort of Italian patients with temporomandibular disorders

This study aimed to understand the impact of COVID-19 distress on psychological status, features of central sensitization and facial pain severity in people with temporomandibular disorders (TMDs). In this prospective cohort study, 45 adults (19 chronic, 26 acute/subacute TMD) were recruited prior to the COVID-19 outbreak. Baseline assessment took place before the outbreak while a follow-up was performed immediately after the lockdown period. Multiple variables were investigated including age, gender, perceived life quality, sleep quality, anxiety and depression, coping strategies, central sensitization, pain intensity, pain-related disability and oral behaviour. COVID Stress Scales (CSS) were applied at follow-up to measure the extent of COVID-related distress. CSS were significantly higher in those with chronic TMDs compared to those with acute/subacute TMDs (p<0.05). In people with chronic TMD, the variation in anxiety and depression from baseline to follow-up was significantly correlated with scores on the CSS (r = 0.72; p = 0.002). Variations of the central sensitization inventory (r = 0.57; p = 0.020) and graded chronic pain scale (r = 0.59; p = 0.017) were significantly correlated with scores on the CSS. These initial findings indicate that people with chronic TMD were more susceptible to COVID-19 distress with deterioration of psychological status, worsening features of central sensitization and increased chronic facial pain severity. These findings reinforce the role of stress as a possible amplifier of central sensitization, anxiety, depression, chronic pain and pain-related disability in people with TMDs. Trial Registration: ClinicalTrials.gov ID: NCT03990662.

The Impact of Education and Physical Therapy on Oral Behaviour in Patients with Temporomandibular Disorder: A Preliminary Study

Patient education is important in the treatment of temporomandibular disorder (TMD), but little is known about its effect on oral behaviors. We aimed to determine the dominant oral behaviours in patients with TMD and assess the impact of education on such behaviours. Between July 2018 and April 2019, 54 patients diagnosed with TMD according to DC/TMD were recruited. They received physical therapy and were provided education on TMD and offered a list of recommendations for improving their oral behaviours. The patient education process usually lasted for 10–20 min. Of these patients, 48 were reexamined at the outpatient clinic, 3–9 months posttreatment. We recorded the Oral Behaviour Checklist (OBC) score, maximum painless mouth opening (mm), visual analogue scale (VAS) score for pain, and Jaw Functional Limitation Scale (JFLS) score pre- and posttreatment. Wilcoxon signed rank test and paired sample t -test were used for statistical analysis. Results showed that the most dominant oral behaviours included “putting pressure on the jaw” (59.3%); “chewing food on one side” (46.3%); “pressing, touching, or holding teeth together at times other than eating” (33.3%); and “eating between meals” (33.3%). Posttreatment, the patients reported a decrease in “chewing gum” ( P = 0.002 ), “leaning with the hand on the jaw” ( P = 0.013 ), “chewing food on one side” ( P ≤ 0.001 ), and “eating between meals” ( P = 0.007 ), but this change was not significant in subgroups with a follow-up interval of 9 months. We also observed a significant improvement in the maximum painless mouth opening ( P ≤ 0.001 ), JFLS score ( P ≤ 0.001 ), and VAS score ( P ≤ 0.001 ) for pain, posttreatment. In conclusion, patient education can facilitate management of oral behaviours and should be targeted towards specific oral behaviours.

Insufficient Oral Behaviour and the High Need for Periodontal Treatment in Patients with Heart Insufficiency and after Heart Transplantation: A Need for Special Care Programs?

Background: The aim of this cross-sectional study was the assessment of dental behaviour and oral health condition of heart transplant recipients (HTx) in comparison to patients with heart insufficiency (HI). Methods: Patients attending the Department for Cardiac Surgery, Leipzig Heart Center, Germany were recruited. Standardized questionnaires regarding dental behaviour and periodontal complaints were applied. A dental (decayed-, missing- and filled-teeth index) and periodontal examination (periodontal probing depth (PPD) and clinical attachment loss (CAL)) was performed. Based on the oral findings, dental and periodontal treatment need was determined. Statistics: T-test, Mann-Whitney U test, Chi-square test, and Fisher-test (p < 0.05). Results: A total of 201 patients (HTx: 112, HI: 89) were included. HTx patients were significantly more often allocated to dentists (p < 0.01). Furthermore, the HTx patients rated feeling informed appropriately about oral health more often (p < 0.01). HTx patients used interdental cleaning (p < 0.01) and mouth rinse (p = 0.02) more often than HI patients. No differences between groups were present regarding dental status and periodontitis severity (p > 0.05). Periodontal treatment need was high, showing prevalence of 79.5% (HTx) and 87.6% (HI, p = 0.14), respectively. Conclusions: Both groups show insufficient oral behaviour and a high need for periodontal treatment. Special care programs for HTx candidates and recipients appear recommendable.

The Associations of School Oral Health-Related Environments with Oral Health Behaviours and Dental Caries in Children

Creating supportive oral health-related environments in schools is an important strategy for promoting schoolchildren’s oral health. This study determined the associations between school environments and children’s oral behaviour and dental caries. The data on school oral health-related environments were obtained through observation and interviews. Oral behaviour and dental caries data were collected through interviews and oral examinations of 984 sixth grade children. χ2 and multiple logistic regression, adjusted for sociodemographic and economic status, other school environment variables, and oral behaviour were used. Providing fresh fruit with school meals was associated with low sweets consumption and low caries levels. Children’s daily sweets consumption was positively associated with sweetened milk sales in schools. Selling sweetened beverages, including sweetened milk, sweetened drinks, and soft drinks, was associated with high caries levels, while selling meat and crispy packed snacks was associated with low caries levels. Children in schools with integrated oral health education were significantly more likely to brush their teeth twice a day and to brush after lunch. In conclusion, school oral health-related environments, especially available food choices, were associated with sweets consumption behaviour and caries levels. Children in schools with integrated oral health education had better brushing habits.
