Dental decisions--an emotional experience?

This article discusses the psychological literature on emotion, highlighting the effect of emotion on decision-making. This is applied to the example of dentistry. Clinical Relevance: This article explores how the everyday decisions of both the patient and the dentist are influenced by their emotions.     

Socio–Economic Disparities in Dental Health and Dental Care Utilisation Among Older Chinese

IntroductionDental care is mostly excluded from healthcare coverage in China. This study examines disparities in dental care and in the costs of such care, according to insurance type and socio–economic status, among Chinese older adults.MethodsThe data were obtained from the 2015 China Health and Retirement Longitudinal Study (CHARLS). A final sample of 5,230 respondents was included, with a mean age of 72 years. Edentulousness, any dental visit and per-patient dental care expenditure were used as outcome variables. Both unweighted and weighted logistic regression analyses were used to examine the association of socio–economic status (education, insurance type and income) associated with edentulousness and use of dental care.ResultsWe found that 28% of Chinese older adults have no remaining teeth and that only 19% had used dental care in the past year. The uninsured and those with rural resident insurance had edentulousness rates of 31%, while the edentulousness rate in those with urban employee insurance was 19%. About 13% of the uninsured study respondents and 15% of those with rural resident insurance had used dental care compared with 30% of those with urban employee insurance. Those in the highest income and education groups and those enrolled in a plan with a lower coinsurance rate had a higher likelihood of using dental care services and spending more on dental care than did those in the lowest socio–economic groups.ConclusionsDental care disparities in China may be reduced through increasing the proportion of the population with insurance and expanding the range of dental treatments covered by all three major insurance schemes.     

Chinese Journal of Dental Research启事

该课题组研究用血管化颌下腺移植代替泪腺治疗角结膜干燥症已经取得令人瞩目的成绩，在国内外有较大影响。本文针对颌下腺移植术后腺体功能休眠期可能导致治疗失败的潜在危险，采用不同的无创刺激方法促进移植的腺体保持分泌功能。研究发现用辣椒素霜剂涂抹腺体表面的皮肤行之有效，与其他方法比较，具有使用方便、刺激性小、药效持续时间长、患者容易接受并能坚持治疗等优点，是目前较好的辅助治疗和预防并发症的方法。经文献检索，这种针对性很强的方法尚属首次报道，因此我愿向本刊推荐这篇文章通过“快速通道”发表。     

Dental implants--isn't it about time?

Long-term studies indicate that dental implants are the most successful restorations fabricated and placed by dentists; however, only 30 percent of the dentists in this country restore implants on a regular basis. This article provides a six-step process for adding implant restoration to the regular services general practitioners provide for patients.     

Dental ceramics: what's new?

The advances in dental ceramic materials and systems continue to be related to improvements in strength, fitting accuracy and aimed towards avoidance of the use of metal substructures both in posterior and anterior teeth. Many of the changes seen within the last few years have been associated with modifications to, and improvements of, existing techniques. These are considered in this paper, and ceramic post systems are also reviewed.     

Dental TechMIealthier Teeth, Less Pain

Does hearing the whine of a dentist's drill make you cringe?~2 If so~3,you're not alone. Surveys show that about 12million Americans are so scared of~4 dental treatment that~5 they skip regular professional dental care altogether. Yet recent advances in dental technology may soon make a dental appointment no more unpleasant than getting a haircut~6. The best way to avoid drilling and filling cavities is by preventing them in the first place~7. Researchers at the National Institute of Dental Research in Bethesda,Md.~8, are tes-     

Dental regeneration and materials—a partnership

Considerable focus on the biocompatibility of dental materials over the last three decades has provided a platform for a wealth of studies on the cellular and molecular responses of the cells of the pulp to injury, both from the disease process and from subsequent restorative intervention. These studies have been fundamental to understanding not only how we can achieve a biocompatible response during restoration of dental disease but also how we can exploit the pulpal cellular responses to achieve wound healing and tissue regeneration in the dentine–pulp complex. This article examines the responses of the pulp to injury and the events leading to tissue regeneration. As new biologically based regenerative therapies emerge for the dental tissues, it is important that these develop in partnership with more traditional approaches using dental materials.
