Dentists evaluate their patients: An empirical investigation of preferences

Dental treatment is a dyadic encounter. Yet research on the dentist-patient dyad has tended to focus on patient perceptions of dentist, to the neglect of dentist perceptions of patient. Previous theoretic and qualitative work on caregiver perceptions of patients suggested three dimensions of evaluation. Dentists (N=618) rated their patients on items taken from two prior studies. Dentists' responses were subjected to confirmatory factor analysis. The analysis substantiated the existence of three evaluative dimensions: compliance, tractability, and likability. Further analysis showed that the three dimensions formed a Guttman simplex, revealing a second-order factor of selectivity and allowing a classification of dentists on the basis of patient selectivity.This study was funded by a grant from the University of Connecticut Research Foundation.     

A multivariable analysis of patient dental satisfaction and oral health-related quality-of-life. A cross-sectional study based on DVSS and OHIP-14

Objective. The aim of this paper was to study the association between dental satisfaction and oral health-related quality-of-life (OHRQoL) when controlling for individual, clinical and psychological factors. Materials. Secondary analysis was conducted using data from a large study carried out in the Swedish region of Värmland in 2004. The questionnaire included demographic variables, clinical assessment and the following instruments: the Dental Visit Satisfaction Scale (DVSS), the short version of Oral Health Impact Profile (OHIP-14) and a modified version of the revised helping alliance questionnaire. Internal consistency analysis was undertaken on the instruments to assess reliability; bivariate comparisons were assessed to compare DVSS scores with individual factors (age, gender and education). In addition, a three step hierarchical multiple regression analysis was performed with DVSS as a dependent variable. Results. Data were completed for 485 randomly selected patients. The mean age of participants was 43.5 years, 54.6% were women,and 41.2% had high education. The median DVSS score was 48 (range 10–50) and the median OHIP was 3.0 (range 0–56). All the instruments showed good reliability. Bivariate analysis showed that females were more satisfied than males (p ≤ 0.01) and patients of 50 years or older were more satisfied than the younger ones (p ≤ 0.05). Finally, the following variables explained 31% of the variance of being very satisfied with dental visit: a good OHRQoL and patients' positive perceptions of the relationship with their care provider. Conclusion. This study showed positive associations between dental satisfaction and OHRQoL when controlling for related factors. The result suggests that care providers should take into account the various dimensions of OHRQoL rather than use only clinical measurements when they evaluate patient satisfaction.     

Orthodontic treatment and referral patterns: A survey of pediatric dentists,general practitioners,and orthodontists

Objective

This study aims to assess the orthodontic diagnostic skills, referral patterns, and the perceptions of orthodontic benefits of pediatric and general dentists in comparison with orthodontists.

Materials and methods

Two online surveys were e-mailed to pediatric dentists, general dentistry practitioners, and orthodontists registered as members of the Saudi Dental Society and the Saudi Orthodontic Society. The surveys included questions about the type of orthodontic treatment provided, referral trends, and timing; presumed benefits associated with successful orthodontic treatment; and diagnosis and treatment plans of seven cases representing different malocclusions.

Results

In total, 25 orthodontists, 18 pediatric dentists, and 14 general practitioners completed the survey. Only 38.8% of pediatric dentists and 7.1% of general practitioners reported that they practiced orthodontics clinically. The perceptions of the three groups toward the benefits of orthodontic treatment were comparable in the psychosocial areas. However, the orthodontists perceived significantly lesser effects of orthodontic treatment on the amelioration of temporomandibular disorder (TMD) symptoms. Pediatric dentists tended to rate the need and urgency of treatment higher, while general practitioners tended to rate the need of treatment lower. The selected treatment plans for three early malocclusion cases showed the greatest discrepancies between the orthodontists and the other two groups.

Conclusions

The orthodontists consistently and significantly downplayed the perceived benefit of orthodontic treatment to reduce TMD symptoms. Also, while there was a similarity in the diagnosis, there were notable differences in the proposed treatment approaches, perceived treatment need, and timing of intervention between the three groups of practitioners.     

A 10-year survey of compliance with recommended procedures for infection control by dentists in Beijing

Objectives: This study aimed to survey changes in practices of infection control (IC) procedures by dentists in Beijing between 2000 and 2010. Methods: Data were based on the feedback of 592 and 769 dentists surveyed in 2000 and 2010, respectively. Statistical analysis was conducted using Pearson’s chi‐squared test. Results: Response rates of 95% (2000) and 94% (2010) were achieved. The percentages of dentists who had received training in IC were 62.96% (2000) and 76.21% (2010). Improvements in practices in 2010 over those in 2000 included increases in: the percentage of vaccination for hepatitis B virus from 32.66% to 68.14%; the routine use of gloves from 73.31% to 99.73%; the use of face shields or eyewear as protection against splatter during dental treatment from 13.94% to 95.45%; the use of protective gowns from 14.51% to 54.23%; the use of high‐volume suction from 11.19% to 74.34%; routine changing of gloves between patients from 63.25% to 99.22%; pressured steam sterilisation of dental handpieces between patients from 41.24% to 96.10%, and the flushing of dental unit waterlines after each treatment from 42.01% to 73.49%. Conclusions: Although compliance with recommended IC practices by dentists in Beijing improved between 2000 and 2010, not all dentists are properly familiar with IC procedures. Education in IC in dental schools and in continuing training in hospitals, and mandatory regulations are needed to improve IC practices in dental health care settings.     

影响部队人员口腔卫生服务利用的多因素分析

目的以Logistic回归方法分析部队人员口腔卫生服务利用与否的某些影响因素的关系,为建立我军合理有效的口腔卫生服务体系提供依据。方法采用分层、整群、随机抽样方法,抽取陆军、海军、空军团以下单位部队人员进行调查,用Logistic回归建立卫生服务利用的就诊概率模型。结果调查总人数为1 269人,单变量分析的结果显示,文化程度高者、军衔高者、年龄高者牙科就诊率较高;多变量分析的结果表明,年龄、兵源、兵种、军衔、口腔疾病治疗要求、龋齿、第三磨牙阻生7个变量有统计学意义。结论我军部队人员的口腔卫生服务利用主要取决于多种因素的影响。
