Influence of customized therapy for molar incisor hypomineralization on children's oral hygiene and quality of life.

OBJECTIVE: The aim of this clinical follow-up study was to demonstrate the effects of different therapeutic strategies for hypomineralized teeth on patients' oral health. The treatment results were characterized by changes in the extent of hypersensitivity and plaque accumulation, as well as reductions in nutritional restrictions. MATERIAL AND METHODS: The impacts of therapy, including the use of fluoride varnish, fissure sealants, fillings, and stainless steel crowns, were evaluated in 78 children (mean age 8.5 years). We followed recommendations according to the Molar Incisor Hypomineralisation Treatment Need Index for customized treatment. The Quigley Hein Index, the Schiff Cold Air Sensitivity Scale, Wong-Baker Faces Scale, and dietary-limiting parameters were assessed before and after therapy for comparison. RESULTS: Plaque accumulation and hypersensitivity decreased after completion of therapy. The improvements were greater for individual teeth (Quigley Hein Index for teeth treated with stainless steel crowns from 4.19 to 2.54) than for those of the whole dentition (high-severity category from 2.67 to 2.20). Problems with food intake were minimized via therapy, with the greatest influence observed for patients who were also in the high-severity category. CONCLUSIONS: Therapy for affected teeth in children has positive effects on oral health and quality of life.

Development and validation of a scale measuring the locus of control orientation in relation to socio-dental effects.

AIM: To develop a socio-dental impact locus of control scale (SILOC) and to study its relationship with oral health status as well as dental attendance. STUDY DESIGN: Observational cross-sectional study design. METHOD: A seven-item SILOC scale based on locus of control and the WHO international classification of diseases' criteria for "Disability" in relation to oral health was developed. In the pilot study, 100 adolescent school children returned completed forms containing the multidimensional health locus of control (MHLC) and the (SILOC) scale. After confirmation of reliability and validity, 509 adolescent school children returned completed SILOC questionnaires and were examined for caries, plaque and gingivitis. A history of postponement of needed dental treatment was also elicited. RESULTS: The SILOC scores were highly correlated with the MHLC scores. Factor analysis revealed a two-factor solution accounting for 59 % of the variance. A Cronbach's alpha of 0.75 showed its internal consistency. Those with higher SILOC scores had greater levels of caries, plaque, gingivitis, and a history of postponing needed dental visits. Multiple logistic regression analysis after adjusting for potential confounders showed that those with high SILOC scores were more likely to have caries (OR = 3.32, p < 0.001), plaque (OR = 1.83, p = 0.026), gingivitis (OR = 1.80, p = 0.012) and a history of 'Postponement of needed dental treatment' (OR = 4.5, p < 0.001) as compared with the others. CONCLUSIONS: The SILOC scale showed satisfactory reliability and validity in measuring locus of control orientation in an Indian adolescent population.

Periodontal disease awareness among pregnant women in the central and eastern regions of Saudi Arabia.

AIM: The purpose of this study was to assess the knowledge and awareness regarding periodontal disease and its effects on pregnancy among pregnant women in the central and eastern regions of Saudi Arabia. METHODS: In this cross-sectional survey, self-administered, structured questionnaires were distributed to 300 pregnant women who were chosen randomly from attendees of maternity health care centers in the central and eastern regions of Saudi Arabia. The questions were developed from literature reviews of articles. The questionnaire addressed personal and sociodemographic variables, periodontal health awareness, and knowledge of pregnant women. The questionnaire was translated into Arabic and was pretested during the pilot study on a random sample of 50 pregnant women. Data were analyzed by χ(2) -tests, with the level of significance set at P < 0.05. RESULTS: An overall response rate of 81% was obtained. Approximately 53% had a higher level of education, but only 21% knew how to define dental plaque and 30% knew its harmful effects. Almost 73% stated that gum disease could be prevented through toothbrushing and flossing. Approximately 97% of the respondents knew the negative effect of smoking, while only 12% knew there was a possible relationship between periodontal disease and adverse pregnancy outcomes. CONCLUSION: The results of this cross-sectional study found that there is limited knowledge and awareness about periodontal disease and its possible effects on pregnancy among pregnant women attending maternal health care centers in the central and eastern regions of Saudi Arabia.

Derivation of the short form of the Oral Health Impact Profile in Spanish (OHIP-EE-14).

BACKGROUND AND OBJECTIVE: The Oral Health Impact Profile is the most frequently used and validated of the Oral Health Quality of Life instruments. Several short versions have been developed; and a validation of the OHIP-49 in Spanish has been published. The objective was to develop the short version of the Oral Health Impact Profile in Spanish (OHIP-EE-14). METHODS: Cross-sectional study. One hundred and thirty-one persons aged ≥60 years attending a social centre for the elderly, residents of a nursing home and persons seeking dental care at a dental school in Mexico City were interviewed and examined. The validity of each of the 49 questions was evaluated, and, to construct the short version, 14 items were selected. The perceived need for dental treatment, number of teeth, presence of coronal caries, root caries, presence of dental plaque and utilisation of removable prosthesis were measured. Internal consistency, repeatability and discriminant validity were calculated. RESULTS: The OHIP-EE-14 was reliable (Cronbach's-α = 0.918, ICC = 0.825). Significant associations were found between OHIP-EE-14 and the number of teeth and perceived need for dental treatment. CONCLUSIONS: The OHIP-EE-14 is a reliable and valid instrument and can be used in subjects aged 60 years and over from Mexico City.

The German version of the Child Perceptions Questionnaire (CPQ-G11-14): translation process, reliability, and validity in the general population.

The aims of this study were to develop a German version of the Child Perceptions Questionnaire (CPQ11-14, a measure of oral health-related quality of life in 11-14-year-old children) and to assess the instrument's reliability and validity in German children ages 11-14. The English original version of the CPQ11-14 questionnaire was translated into German (CPQ-G11-14) by a forward-backward translation method. Reliability was investigated in 1,061 subjects aged 11-14 years from a regional sample (Wernigerode, Saxonia-Anhalt, Germany) who were recruited during the annual dental public health examination. The subjects completed the CPQ-G11-14 and were clinically examined for the presence of dental caries, plaque accumulation, and malocclusion. In the reliability assessment, questionnaire summary score test-retest reliability was excellent (intraclass correlation coefficient, 95% confidence interval (CI) = 0.83, 0.73-0.94) and internal consistency was satisfactory (Cronbach's alpha, lower limit of CI = 0.87, 0.86). Validity of the CPQ-G11-14 questionnaire was supported by correlations with global ratings of oral health and overall well-being that were moderate in magnitude and met expectations (r = 0.35; 95% CI, 0.30-0.40 and r = 0.30; 95% CI, 0.24-0.35, respectively). In conclusion, the German version of the CPQ11-14 was reliable and valid in a general population of 11-14-year-old German children.

Relationship between oral health-related knowledge, attitudes and behavior among 15-16-year-old adolescents: a structural equation modeling approach.

OBJECTIVE: The aim of this study was to confirm the previously observed attitudinal factor structure related to behavioral change and the knowledge-attitude-behavior model on dental health and hygiene among adolescents. MATERIALS AND METHODS: The study population consisted of all 8(th) and 9(th) graders (15-16 years) who started the 2004-2005 school year in Rauma, Finland (n = 827). Data on knowledge, attitudes, toothbrushing and using fluoride toothpaste were gathered by questionnaires. Hypothesized structure included four attitudinal factors related to dental health and hygiene: 'importance of toothbrushing when participating in social situations' (F1), 'importance of toothbrushing for health-related reasons and better appearance' (F2), 'being concerned about developing caries lesions' (F3) and 'importance of toothbrushing for feeling accepted' (F4). Structural equation modeling (SEM) was used to test the hypothesized model: pathways lead from knowledge to behavior both directly and via attitudes. The hypothesized model was also modified by removing non-significant pathways and studying the inter-relationships between attitudes. RESULTS: A confirmatory factor analysis revealed that factor F4 had to be removed. In the final model, knowledge influenced behavior directly and via two attitude factors, F1 and F2, which were inter-related. 'Concern about developing caries lesions' was a background factor influencing only knowledge. The final factor structure and SEM model were acceptable-to-good fit. Knowledge had a smaller effect on behavior than on attitudes. CONCLUSIONS: Our results support theories about the causal knowledge-attitudes-behavior chain, also for adolescents' oral health-related behaviors.

Dental training and changes in oral health attitudes and behaviors in Istanbul dental students.

The aim of this study was to examine the changes that occur in the oral health attitudes and behaviors of dental students in Istanbul, Turkey, during their dental education. The Turkish version of the Hiroshima University-Dental Behavioral Inventory (HU-DBI) was distributed among 757 dental students at the Dental Faculty, Istanbul University. The response rate was 72 percent. Chi-square and logistic regression models were used for statistical analysis. The mean HU-DBI score of the clinical students was significantly higher than that of the preclinical students. Preclinical students significantly more often believed that it was impossible to prevent gum disease with toothbrushing alone and worried about the color of their teeth and bad breath. Most of them brushed their teeth with strong strokes, thought the condition of their teeth was getting worse despite daily toothbrushing, and would seek dental care only when symptoms arise. Clinical students more often used disclosing solutions to see how clean their teeth were and complained of bleeding gums. The variation in favorable oral health attitudes/behaviors appeared to reflect the students' educational training experience. The findings of this study highlight the relatively poor oral health behaviors of Turkish dental students, which should be improved by means of comprehensive programs that aim to promote their own dental hygiene practices and preventive oral health knowledge from the start of dental training.

Sense of coherence and oral health in dentate adults: findings from the Finnish Health 2000 survey.

AIM: To assess the relationship between sense of coherence (SOC) and oral health, and the role of oral health-related behaviours in this relationship. MATERIALS AND METHODS: This is a cross-sectional study of 5401 dentate adults who participated in the nationally representative Health 2000 Survey in Finland. The survey gathered information on SOC, demographic characteristics, education, income, pre-existing diabetes, daily smoking, dental attendance, toothbrushing frequency and sugar intake frequency. Oral health was assessed through clinical outcomes, such as number of teeth, number of decayed teeth and extent of periodontal pockets and perceived oral health. RESULTS: A strong SOC was related to having more teeth, fewer decayed teeth, lower extent of periodontal pockets and good perceived oral health after adjustment for confounders, such as demographic and socioeconomic factors (all p0.003). These associations were attenuated but remained significant after further adjustment for potential mediators (oral health-related behaviours), except for the association of SOC with the extent of periodontal pockets, which was fully accounted for by pre-existing diabetes, oral health-related behaviours and dental plaque (p=0.549). CONCLUSION: SOC is positively associated with various aspects of adult oral health, in part because of the better oral health-related behaviours among people with a strong SOC.

The importance of psychological factors in the maintenance of oral health: a study of Swedish university students.

PURPOSE: The aim of this study was to investigate the predictive value of the traditional multidimensional health locus of control (MHLC) scale, a corresponding dental health locus of control (DHLC) scale and dental health values (DHVs) regarding students' dental health before and after a video programme that presented information about dental diseases and instructions on oral hygiene. MATERIALS AND METHODS: A group of 217 university students participated in this study. Before the video programme was presented, assessments were made of MHLC, DHLC and DHVs. Plaque and gingival indices were obtained in a clinical examination conducted before (plaque index [PLI] 1 and gingival index [GI] 1) and 10 weeks after (PLI 2 and GI 2) the presentation of the programme. RESULTS: The percentage of tooth surfaces exhibiting plaque and of sites involving gingivitis decreased and was statistically significant between baseline and re-examination for both males and females. The females exhibited statistically significant better PLI 1 and GI 1 values and stronger DHVs than males. Also, better GI 1 values were found to be statistically significant and related to stronger DHVs for females. A stronger trust in the dental health personnel regarding the dental health was related to more gingivitis at the initial examination (GI 1). For males, stronger internal DHLC was related to more plaque at the final examination (PLI 2). CONCLUSION: The only psychological scales that showed some relationship to the measures of dental health were DHLC and DHVs. Gender was the strongest related variable to dental health.

Oral health status of children with congenital heart disease and the awareness, attitude and knowledge of their parents.

The oral health status of children with congenital heart diseases and the parental awareness on maintaining good oral health and attitude towards preventive dental health measures were evaluated. A total of 170 children between the age group of 1-16 yrs belonging to both genders, with the history of congenital heart disease from Sree Chitra Tirunal Institute of Medical Science and Technology, Thiruvananthapuram and Narayana Hrudayalaya Institute of Medical Sciences, Bangalore were examined. Oral lesions and caries experience were recorded using modified WHO oral health assessment form. Oral hygiene of the children with congenital heart disease was found to be poor with tongue coating (50.6%), plaque (41.8%), calculus (35.3%), and caries (42.4%). Parental awareness on the importance of maintaining good oral hygiene, preventive dentistry, medicinal decay and its systemic effects has been found to be very poor. Dentistry should give priority to patients whose general health may be put at risk by poor dental health. Closer cooperation between Pediatrician, Pediatric Cardiologists and Pediatric Dentists could help improve dental care for these children.

Relationship between mothers' sense of coherence and oral health status of preschool children.

OBJECTIVE: The aim of the present study was to investigate the relationship between mothers' sense of coherence (SOC) and oral health status in a representative sample of 5-year-old preschool children. METHODS: A cross-sectional study was conducted in Belo Horizonte (Brazil) on a sample of 546 mothers and their 5-year-old children, randomly selected from preschools. Data were collected through questionnaires (mothers), the short version of Antonovsky's SOC scale (SOC-13) and clinical dental examinations (children). Simple and multiple logistic regression analyses were performed on the data. The following 8 outcome variables were selected: dental caries, filled and missing teeth, dental pulp exposure due to caries, dental root fragment, visible plaque, gingivitis and supragingival calculus. The examination was carried out by 2 trained, calibrated examiners. RESULTS: Mothers with a lower SOC were more likely to have children with decayed teeth (OR = 1.59, 95% CI = 1.01-2.29), dental pulp exposure (OR = 1.99, 95% CI = 1.06-3.77) or filled teeth (OR = 1.85, 95% CI = 1.12-3.06) regardless of the child's social class and gender. CONCLUSION: The data indicate that mothers' SOC is an important psychosocial determinant of the oral health status among preschool children.

Oral health status and oral hygiene habits of an adult Turkish population on dialysis.

PURPOSE: The present study was undertaken to evaluate the oral health status and oral hygiene habits of dialysis patients. MATERIALS AND METHODS: A total of 145 patients on dialysis were evaluated in two centres. Evaluation included oral examination of soft and hard tissues and completion of a questionnaire that was used to gather information about demographic, socioeconomic, medical and dental status and oral hygiene attitudes of patients. Awareness of the importance of oral health was also determined by four yes/no questions within this questionnaire. RESULTS: Of the 145 patients, 89 (61.4%) were presently candidates for renal transplantation. Nineteen patients (13.1%) were edentulous and nearly half of the patients (n=69, 47.6%) had 15 or fewer remaining teeth. Dentate patients who regularly brushed twice a day and flossed were few (n=18, 14.3%; n=3, 2.4%, respectively). In addition, plaque score was more than 50% in most of the dentate patients (93.7%). Gingival bleeding was reported by about two thirds of dentate patients (67.5%). None of the patients were referred to a dentist or were attending regular dental care. The percentage of patients who were aware of oral cavity-related infections and importance of oral hygiene following renal transplantation was very low (20.7% and 9.7%, respectively). CONCLUSIONS: Poor oral health, unsatisfactory daily oral hygiene habits and insufficient awareness of the importance of oral health is frequent among Turkish dialysis patients. Dentists and nephrologists should work in close cooperation in order to raise awareness and encourage regular dental controls.

Stress and periodontal disease.

Stress is an association of physiological and psychological reactions of a person confronted to a change of situation he cannot face. The relationship between stress and any disease is explained by hormonal modifications and behavioural changes induced by the stress. The evidence of such an association between stress and periodontal disease will be evaluated. The purpose of the present review article is to differentiate between old feelings and knowledge, and present findings which show that a lot of prospective studies are still needed for a more defined role of stress and periodontal disease.

Attitudes of dental and medical students in their first and final years of undergraduate study to oral health behaviour.

OBJECTIVE: To compare differences in attitude to oral health behaviour amongst medical and dental students when they were in years 1 and 5 of University study respectively. METHODS: Medical and dental students of Peking University in Beijing, China were invited to take part in this study. The original version of the Hiroshima University-Dental Behavioural Inventory (HU-DBI) was written in Japanese. After testing the validity of both English and Chinese versions, the revised Chinese version of the HU-DBI was administered to new medical and dental students. In their final year of University study, the same questionnaire was again administered. RESULTS: Significant differences were found for 13 of 21 items, reflecting an improvement in oral health attitudes and behaviour in final year dental students when compared with the time they were entrants. This difference was not found to be significant in the sample of medical students. CONCLUSIONS: There were significant differences in oral health attitudes and behaviours in dental students between entrance to University and the final year of their study. The same was not found to be true for medical students.

Approximal plaque and gingival sulcus bleeding in routine dental care patients: relations to life stress, somatization and depression.

OBJECTIVES: Previous research on relations between life stress and periodontal conditions was often based on indicators of periodontal destruction history and stimulus-specific measures of life stress. The present study was undertaken to compare patients showing different degrees of gingival sulcus bleeding with patients without signs of bleeding, using an instrument measuring cognitive impacts of events and assessing reported symptoms of depression and somatization. Additionally the patient groups were compared with regard to dental status and dental visiting behaviour. Analog comparisons were conducted in patients with different degrees of approximal plaque. MATERIALS AND METHODS: 140 routine dental care patients attending a private dental practice were examined. Measurement devices were the sulcus bleeding index (SBI), the approximal plaque index (API), the Dental Avoidance Scale, the Life Experience Survey (LES), the Impact of Event Scale with the subtests cognitive intrusion and cognitive avoidance, and the SCL-90-R subscales somatization and depression. RESULTS: Patients with high API scores differed from their zero-score counterparts in dental avoidance and time since last visit only. By contrast, subjects scoring high in the SBI not only had more missing teeth and reported more dental avoidance than their zero-score counterparts but also had elevated scores in intrusive and avoidant thoughts related to a stressful event as well as in symptoms of somatization and depression. No difference was found for the measure of stimulus specific recent life events (LES). CONCLUSIONS: The results suggest that cognitive preoccupation with adverse events and the presence of somatization and depression symptoms might play a role in gingival inflammation.

Oral health and health behavior in patients referred for open-heart surgery.

OBJECTIVE: Little is known about the dental health and health behavior of patients referred for open-heart surgery because of severe heart disease. Yet, coronary atherosclerosis has been suggested to be an inflammatory disease in which chronic dental infections may trigger pathogenic mechanisms in the walls of arteries. In epidemiological studies periodontal disease in particular has been linked with coronary heart disease (CHD). STUDY DESIGN: We set out to investigate by means of clinical examination, x-ray, and questionnaire the oral health status, health-related behavior, and conceptions of 256 CHD patients referred for open-heart surgery in the Kuopio University Hospital. The patients' heart disease was New York Heart Association grades II-IV. For comparison, 250 age- and sex-matched non-CHD patients were also studied. Differences between groups were analyzed conventionally and with the Total Dental Index (TDI), which uses linear modeling and logistic regression analyses to summarize periodontal factors and other signs of oral infections. We expected to find neglected dental care and worse oral health situation among the CHD patients. RESULTS: Edentulousness was seen in 35% of the CHD group and in 15% of the non-CHD group (P < .001). The CHD group had significantly lower number of teeth (8.8 +/- 9.1) than the non-CHD group (17 +/- 10.5; P < .001). No dental appointment in the past 10 years was reported in 66% of the CHD patients and 35% of the non-CHD patients. Forty-nine percent of the CHD group and 69% of the non-CHD group had had a dental visit within the past 2 years (P < .001). Daily tooth brushing was reported by 46% of the CHD group and 56% of the non-CHD group (P < .05). Only 2% of the CHD group and 8% of the non-CHD group flossed daily (P < .001). TDI scores were significantly higher in the edentulous than in the dentate study groups (P < .001), but no difference was observed between CHD and non-CHD patients of the same dentate or edentulous status. Mean TDI score was 3.2 +/- 0.8 in edentulous CHD patients and 3.1 +/- 0.4 in edentulous non-CHD patients; the scores in the dentate patients were 2.5 +/- 0.9 in the CHD group and 2.4 +/- 2.0 in the non-CHD group. The TDI score appeared almost significant a predictor of CHD when used as a dependent variable in logistic regression analysis (P = .08). CONCLUSION: Worse oral health status and less satisfactory oral health behavior were observed in the CHD patients than among the cardiologically healthy.

Health behaviors and their relation to metabolic control and periodontal status in type 2 diabetic patients: a model tested using a linear structural relations program.

BACKGROUND: Although it has been reported that diabetic control is beneficial in managing periodontal disease, there are few studies in the literature where the relationship between singular behavioral factors and periodontal status has been examined. The aim of this study was to examine the simultaneous interrelationships among selected medical/dental variables and 5 behavior components with general health behavior (GHB), perceived fatigue (PF), diet control (DC), regular diet (RD), and dental behavioral inventory (HU-DBI) scores, using data from a study of 102 type 2 diabetic patients. METHODS: A hypothesized model was tested by a linear structural relations program (LISREL). RESULTS: There was a significant correlation between oral health behavior and calculus accumulation (r = 0.399; P<0.001). Correlations were found between calculus and periodontal status measured by gingivitis index and probing depth (r = 0.232; P<0.05, r = 0.279; P<0.01, respectively). The final model was found to be consistent with the data (chi2 = 55.0, df = 47, P = 0.197; GFI = 0.922). Oral health behavior affected periodontal status through its effect on calculus but not plaque accumulation. General health behavior had significant effects on oral health behavior and diet behavior (P<0.05 and P<0.001, respectively). Diet behavior affected both plaque accumulation and metabolic control (P<0.05 and P<0.01, respectively). However, the result was the virtual absence of a significant pass coefficient between metabolic control and periodontal status. CONCLUSIONS: The severity of the 2 diseases seemed to be connected indirectly through health behaviors such as diet behavior and oral health behavior.

Adolescents' sense of coherence, oral health status, and oral health-related behaviours.

OBJECTIVE: To investigate the relationship between sense of coherence (SOC) and oral health. It was hypothesised that subjects with better oral health status and better oral health-related behaviours have higher levels of SOC. METHODS: A cross-sectional study was conducted in Goiânia-GO, Middle-West Brazil, on a sample of 664 15-year-olds randomly selected from schools. Data were collected through questionnaires, the short version of Antonovsky's SOC Scale (13-item) and clinical dental examinations. Multiple logistic regression and polytomous ordered regression were used in the data analysis. Two sets of outcome variables were selected for the analyses: oral health status (dental caries, oral cleanliness, and periodontal disease), and oral health-related behaviours (frequency of sugar intake, toothbrushing frequency, and pattern of dental attendance). RESULTS: Adolescents' SOC was associated with their caries experience in anterior teeth (OR=0.81 for 10 units increase in SOC scale; 95% CI=0.66-0.98), but the relationship did not remain significant after controlling for other factors. Adolescents with higher SOC were less likely to visit the dentist mainly when in trouble, compared with those with lower SOC (OR=0.83, 95% CI=0.71-0.98), or equivalently more likely to visit for mainly check-ups. Other measures of oral health status and behaviours were not significantly associated with SOC. CONCLUSION: SOC was identified as a psychosocial determinant of adolescents' oral health-related behaviour, particularly affecting their pattern of dental attendance.
