Communication Skills Teaching Methods in Dental Education - a Review.

Communication skills of dentists have been demonstrated to be part of the good dental practice. The aim we set ourselves in this study was to review the literature related to the methods of teaching communication skills at dental faculties, and develop a handout in the Bulgarian language about leading a successful conversation with a patient.According to some authors, the most important principles for effective communication training include the use of practical exercises, clinically relevant scenarios, students' self-assessment tools, videotapes, participation of patient actors, and training in small groups. Another communication training program is the so-called Miller pyramid. Using the method of objective structured clinical examina-tion (OSCE) can also be an effective way of teaching communication skills to dental students. The conclusion to be made is that communication skills should be taught across the entire dental curriculum as this leads to better understanding and sufficient outcome.

Risk factors for development of chronic periodontitis in Bulgarian patients (pilot research).

The aim of this work was to assess the risks and analyse the risk factors for development of chronic periodontitis in Bulgarian patients. The quality of life was investigated in a cohort of 228 patients with chronic periodontitis. Within the frame of this study, pilot research (a case-control study) was conducted among 80 patients (20 cases and 60 control patients without periodontitis) to evaluate the risk for development of chronic periodontitis. The minimum sample size of patients was determined based on power analysis for sample-size calculation. The mean age of participants in the control group was 31.33 ± 9.38 years and in the case group, 33.00 ± 11.52. Data were accumulated by clinical and sociological methods. Descriptive statistics and multi-factor logistic regression analysis (Backward Conditional procedure) were used. One-factor dispersion analysis showed that, of the 12 studied risk factors, the following variables were significant: stress, diabetes, presence of calculus, overlapping and misaligned teeth (P < 0.05). Multiple logistic regressions were applied to evaluate the association between the variables. Three predictors were selected in the final logistic regression equation: diabetes (B = 4.195; P = 0.001), crooked and overlapping teeth (B = 3.022; P = 0.010) and stress (B = 2.882; P = 0.014). The logistic risk assessment model for development of periodontitis has a predictive value of 93.80% (χ2 = 63.91; P = 0.000). Our results confirmed some proven risk factors for periodontal disease. In the studied population, diabetes was the single, most important predictor for development of periodontitis.

Validation of a scale assessing the impact of periodontal diseases on patients' quality of life in Bulgaria (pilot research)

The aim of the paper is to present the validation of a scale for assessing the impact of periodontal diseases on individuals' quality of life in Bulgaria. A pilot research was made among 30 diagnosed patients with periodontitis visiting the Department of Periodontology, Faculty of Dental Medicine, Medical University of Plovdiv, Bulgaria. The minimum sample size of 30 people was established based on a power analysis for sample size calculation. The mean age of participants was 48.95 ± 11.85 years, being 56.67 ± 9.05 years for males and 43.33 ± 9.05 years for females. Standard interviews were conducted using a specific instrument: self-designed questionnaire and a 5-degree ranked scale, containing initially 11 questions. The interviews were repeated after 3 months with the same patients for retest analysis. The data was statistically processed using SPSS v.13 software. Results received after the initial interviews: Cronbach's coefficient (α=0.882), Spearman-Brown coefficient (r sb=0.998), average inter-item correlation coefficient (R=0.426), difficulty of the questions from 0.173 to 0.757 and discrimination power from 0.405 to 0.809. Results after the second interviews: α=0.883, r sb=0.998, R=0.507, difficulty from 0.287 to 0.757 and discrimination power from 0.524 to 0.809. In two of the questions, a low level of inter-item correlation with the rest of the items was found and they were excluded. The final version of the questionnaire contained 9 questions. The validation proved that the developed scale is sufficiently reliable and will be used in the final research, the first one to use such an instrument for measuring oral health-related quality of life in Bulgaria.

O objetivo deste artigo é apresentar a validação de uma escala que mede o impacto das doenças periodontais sobre a qualidade de vida das pessoas na Bulgária. Foi feito um estudo piloto com 30 indivíduos diagnosticados com doença periodontal, entre os pacientes do Departamento de Periodontologia da Faculdade de Medicina Odontológica da Universidade de Medicina de Plovdiv, Bulgária. A amostra mínima de 30 pessoas foi estabelecida baseada em análise de potência para cálculo do tamanho de amostra. A idade média dos participantes foi de 48,95 ± 11,85 anos, sendo de 56,67 ± 9,05 para homens e de 43,33 ± 9,05 para mulheres. Foram feitas entrevistas padronizadas usando um instrumento específico: um questionário com uma escala de 5 graus, contendo 11 perguntas iniciais. As entrevistas foram repetidas 3 meses depois, com os mesmos pacientes, para reanalisar o teste. Os dados foram processados estatisticamente pelo programa SPSS v.13. Os resultados das entrevistas iniciais foram: coeficiente de Cronbach (α=0,882), coeficiente de Spearman-Brown (rsb=0,998), coeficiente de correlação média inter-item (R=0,426), dificuldade das questões de 0,173 a 0,757 e potência de discriminação de 0,405 a 0,809. Os resultados da segunda série de entrevistas foram: α=0,883, rsb=0,998, R=0,507, dificuldade de 0,287 a 0,757 e potência de discriminação de 0,524 a 0,809. Duas das questões apresentaram baixo nível de correlação inter-item e foram excluídas. A versão final do questionário continha 9 perguntas. A validação comprovou que a escala desenvolvida é suficientemente confiável e será usada na pesquisa final, a primeira a utilizar tal instrumento para mensurar a qualidade de vida relacionada à saúde oral na Bulgária.

Cross-cultural validation of the revised temperament and character inventory in the Bulgarian language.

RATIONALE, AIMS AND OBJECTIVES: Health-care professions have long been considered prone to work-related stress, yet recent research in Bulgaria indicates alarmingly high levels of burnout. Cloninger's inventory is used to analyse and evaluate correlation between personality characteristics and degree of burnout syndrome manifestation among the risk categories of health-care professionals. The primary goal of this study was to test the conceptual validity and cross-cultural applicability of the revised TCI (TCI-R), developed in the United States, in a culturally, socially and economically diverse setting. METHODS: Linguistic validation, test-retest studies, statistical and expert analyses were performed to assess cross-cultural applicability of the revised Cloninger's temperament and character inventory in Bulgarian, its reliability and internal consistency and construct validity. RESULTS: The overall internal consistency of TCI-R and its scales as well as the interscale and test-retest correlations prove that the translated version of the questionnaire is acceptable and cross-culturally applicable for the purposes of studying organizational stress and burnout risk in health-care professionals. CONCLUSIONS: In general the cross-cultural adaptation process, even if carried out in a rigorous way, does not always lead to the best target version and suggests it would be useful to develop new scales specific to each culture and, at the same time, to think about the trans-cultural adaptation.

Evaluation of quality of life of patients with oral cavity cancer in three counties of south Bulgaria.

AIM: To evaluate the quality of life of patients with oral cavity cancer in three counties of South Bulgaria. MATERIALS AND METHODS: A standard questionnaire was developed to evaluate the social status. Twenty two patients with oral cancer were interviewed (diagnoses by ICD 9th Revision 141-149). SPSS statistical software version 8.0 was used for statistical analysis employing the alternative analysis and ANOVA. RESULTS AND DISCUSSION: Oral cancer affects 1) mostly men-68.2%, 2) smokers-59.1% (of the people we interviewed, smoking regularly twenty and more cigarettes daily), and 3) people who consume alcohol on regular basis - 40.9% of the interviewees. The life quality of the interviewed people was evaluated on a specially developed five-degree scale. 22.7% of the interviewed people were classified as first scale group characerised with speaking and alimentary disorders, impaired aesthetics and pains in the oral cavity. 36.4% were scored as the second scale group--these had speaking disorders and disorders of the alimentary tract, oral cavity pain without impairment of the orofacial aesthetics. 27.3% were classified as third scale group in which the patients had only two functions impaired. Group five contained 4.5% of all patients with no manifest disorders. CONCLUSIONS: The results suggest that oral cancer patients need a lot of prosthetic care to mend their oral defects and a lot of rehabilitation to restore their ability to function socially, a task which must be realized by a rehabilitation team including the general dental practitioner.
