Difficulties in emotional regulation: association with poorer oral health-related quality of life in the general population

A Cross-Sectional Study to Analyze the Correlation Between Alexithymia and Dental Neglect in Persons Pursuing Dental Care

Background Alexithymia is a personality trait involving difficulties in emotional regulation (difficulties in identifying feelings, difficulties in describing feelings, and externally oriented thinking). It has a negative impact on health as it evokes poor personal hygiene, poor nutrition, and unhealthy behaviors in affected subjects. Identifying alexithymia in the dental setup is vital as it can compromise the patient-dentist relationship, especially in subjects neglecting oral hygiene. Aims The present study aimed to establish an association between alexithymia and dental neglect among adult subjects seeking dental care by using Dental Neglect Scale (DNS), and alexithymia was assessed on the 20-item Toronto Alexithymia Scale (TAS-20). Methods The present cross-sectional survey study included adult subjects of age 20 years or more. For all included participants, a structured questionnaire was given to assess dental neglect on demographic profile, six items of the DNS, and alexithymia was assessed on the 20-item TAS-20. The collected data were analyzed using a Chi-square test keeping significance at the p-value of <0.05. Results In 534 adult subjects, females had high scores for both TAS-20 and DNS along with their related factors. With higher education and increasing age, a significant increase in the mean TAS-20 scores and mean DNS scores was seen in the study participants (high mean DNS scores in females (19.55±3.98) compared to male subjects 19.36±4.34). TAS-20 scores were higher in females (59.31±10.78), factor 1 (DIF) (19.54±5.54), factor 2 (DDF) (15.46±4.05), and factor 3 (EOT) (24.34±4.64). Conclusion The present study, considering its limitations, concludes that there is no association between dental neglect and alexithymia in adult subjects seeking dental care. However, higher DNS and TAS-20 scores are seen in females showing them have difficult descriptions and identification of feelings in dental set-up increasing dental neglect among them.

Association between grandparent co-residence, socioeconomic status and dental caries among early school-aged children in Japan: A population-based prospective study

Globally many children are living with grandparents, and it has been suggested that grandparent co-residence may be associated with dental caries in infants and toddlers possibly through passive parenting style, accompanied by children's cariogenic behaviors such as feeding sugary sweets. However, little is known about this association in schoolchildren, adjusted for socioeconomic status. Therefore, this study investigates the association between grandparent co-residence, socioeconomic status, and dental caries among schoolchildren. All caregivers of first-grade children (age 6-7 years) in Adachi City, Tokyo, were administered a questionnaire about children's grandparent co-residence status and oral health-related behaviors, and responses were linked with dental examination records conducted by school dentists (N = 3,578). Multilevel Poisson regression analysis was applied to examine the association between grandparent co-residence, socioeconomic status, and dental caries status for each individual tooth, adjusting for potential covariates. The percentage of dental caries experience was higher among children living with grandparents (48.9%) than among children living without grandparents (44.0%). The risk for caries, however, did not differ according to grandparent co-residence status when tooth type, child's age and sex, and parental socio-economic status and structure were adjusted (PR, 1.13; 95%CI, 0.90, 1.42). The association between grandparent co-residence and dental caries among early school-aged children in urban Japan was confounded by socioeconomic status.

The role of alexithymia in quality of life impairment in patients with chronic hepatitis C during antiviral treatment

This study aimed to investigate the role of alexithymia in the quality of life of patients with chronic hepatitis C treated with antiviral therapy. A consecutive sample of 124 patients were evaluated at baseline, during, and 6months after treatment with interferon and ribavirin. At baseline past mood disorders and alexithymia and, at each index visit, adverse events, psychological distress, and disease-specific quality of life were assessed with validated instruments. Patients with past mood disorders and alexithymia had impaired levels of quality of life, psychological distress, and treatment-related adverse events. However, after controlling for covariates, poor quality of life was independently predicted by alexithymia and psychological distress before (R(2)=0.60) and 6months after (R(2)=0.69) the antiviral treatment while during treatment (at 3months and the end of therapy) by depression and somatic adverse events (R(2)=0.67 and 0.69, respectively). Alexithymia rather than history of mood disorders resulted to be an independent predictor of impaired quality of life not only before but also 6months after the end of treatment. Given the association with proneness to health-compromising behaviors, clinicians are encouraged to pay closer attention to long-term psychological and somatic effects of antiviral treatment in patients with alexithymic characteristics.

Nothing to smile about

BACKGROUND

Several studies have demonstrated the high incidence of periodontal disorders among patients suffering from mental illnesses, probably because of self-care impairment, the difficult financial conditions, and the lack of motivation. The primary aim of this study was to evaluate the impact of depression and alexithymia on periodontal status. Due to the influence of personality traits on behavior in general, the secondary aim of our study was to investigate the possible impact of personality disorders on dental status.

METHODS

Patients with major depression (DP) referred to our psychiatry unit and healthy individuals (controls) were consecutively enrolled during the period April 2012-September 2012. All the participants to the study underwent a psychiatric evaluation (through questionnaires investigating the presence of depression, anxiety, personality disorders, and alexithymia) and a dental examination through the following indexes: plaque index, gingival index, simplified oral hygiene index, periodontal index.

RESULTS

Fifty DP (aged 56.7±15.2 years) and 40 controls (aged 56.1±15.9 years) were enrolled in the study. DP showed a worse oral hygiene status. In particular, statistically significant differences were found when comparing DP and controls in terms of plaque index, simplified oral hygiene index, gingival index, periodontal index, and oral health impact profile. In addition, periodontal health was found to be negatively related to the severity of depression and the presence of alexithymia. The strength of association between depression and dental indexes was reduced after adjusting for the other psychiatric variables (alexithymia and personality disorders) and was confirmed only for oral health impact profile.

CONCLUSION

Psychiatric variables seem to affect the patients' periodontal status; due to the high frequency of dental problems, patients suffering from mental illnesses should be referred to the oral health services for evaluation.
