Oral health status and practices of dentate Bhil adult tribes of southern Rajasthan,India

Aims : To assess the oral health status of the Bhil tribal population of Southern Rajasthan and to investigate the association of age, oral hygiene and dental visiting practices with oral health status. Design : A cross sectional study of Bhil tribal adults chosen by a multi stage stratified random sampling procedure. Participants : The total sample size was 1,590 male tribal dentate subjects aged 15–54 years. Methods : Clinical recordings of oral hygiene status (OHI ‐ S), caries status (DMFT and DMFS) and treatment needs, and periodontal status (CPI). The Chi square test was applied to discrete data and one way ANOVA for continuous data. Multivariate analyses were carried out to test the association of age, frequency of cleaning teeth, material used for cleaning teeth and dental visiting habits with caries and periodontal status. Results : Debris, calculus and oral hygiene index scores increased with age. The overall mean DMFT and DMFS scores were 5.34±6.48 and 18.94 ± 35.87 respectively. Extraction was the most required treatment (1.74 ± 3.66 teeth) followed by one surface fillings (1.34 ± 1.65 teeth). Shallow periodontal pockets were prevalent (40%) among the 35–44 years age group whereas deep pockets were most common (11.6%) in the oldest age group. More than half the sextants (3.15) were excluded amongst the oldest study group. All the independent variables namely age, frequency of cleaning teeth, substance used for cleaning teeth and visiting habits were statistically significantly related to caries and periodontal status. Conclusions : The study population was characterised by a lack of previous dental care, high treatment needs, high prevalence of periodontal disease and poor oral hygiene. Under these circumstances, the implementation of a basic oral health care programme for the Bhil population is a high priority.     

Sickle cell disease does not predispose to caries or periodontal disease

This study investigated the prevalence of dental caries and periodontal condition in a population with sickle cell disease (SCD), analyzing some associations with disease severity. The Decayed, Missing and Filled Teeth index (DMFT) and Community Periodontal Index (CPI) were recorded for 99 individuals with SCD and 91 matched controls. Socio-demographic status, oral health behaviors, and history of clinical severity of SCD were assessed. Statistical comparisons were performed between the group with SCD and the control group, as well as multivariate logistic regression analyses with DMFT index and CPI as the dependent variables. The mean number of decayed teeth was significantly higher in individuals with HbSS. Older age, female gender, and daily smoking were identified as risk factors for higher DMFT, while older age and absence of daily use of dental floss were risk factors for the development of periodontal disease. In conclusion, risk factors known to cause caries and periodontal disease had more influence on oral health than the direct impact of SCD.     

Dental health in a group of drug addicts in Italy

The caries prevalence, periodontal health, and oral hygiene status were assessed in 124 drug addicts aged 18-34 yr in Mercato San Severino (Salerno), Italy. The years of drug addiction ranged from 1 to 15 yr. The majority used heroin (96%) but all the subjects indicated that they had used more than one drug. The percentage of drug addicts caries free was 6.5%, ranging from no caries free subjects in the group over 29 yr of age, to 11.4% in the group aged 26-29 yr old. Mean DMFT and DMFS scores for all age groups were 12.9 and 36.2, respectively; mean Periodontal Index (PI) and mean Simplified Oral Hygiene Index (OHI-S) scores were 1.37 and 1.71, respectively. The poor dental health in this target group indicates the need for more extensive collaboration between the social and dental health care sectors.     

Low Social Position,Periodontal Disease,and Poor Oral Health‐Related Quality of Life in Adults With Systemic Arterial Hypertension

Background: There is little evidence on the association between periodontal disease and oral health‐related quality of life (OHRQoL) in individuals with chronic diseases, including hypertension. The aim of this study is to identify relationships among sociodemographic characteristics, smoking, tooth loss, dental caries, periodontal status, and OHRQoL in adults with systemic arterial hypertension. Methods: A cross‐sectional study involving 195 adults (mean age: 55.7 years) with systemic arterial hypertension used interviews and oral examinations to collect data on sociodemographic characteristics (age, sex, income); use of antihypertensive medication; smoking; tooth loss; dental caries; periodontal status (bleeding on probing, calculus, and attachment loss); and OHRQoL/oral health impact profile. The Wilson and Cleary (Wilson IB, Cleary PD. JAMA 1995;273:59‐65) conceptual model was used to test direct and indirect relationships among variables using structural equation modeling. Results: Lower age, male sex, smoking, and lower income directly predicted worse periodontal status. Tooth loss, dental caries, worse periodontal status, and smoking were directly linked to poor OHRQoL. Age was indirectly linked to worse periodontal status via income. Income and smoking indirectly predicted poor OHRQoL via periodontal status. Conclusions: Findings support an effect of periodontal disease on OHRQoL in people with systemic arterial hypertension. Periodontal status mediated associations of sociodemographic characteristics and smoking with OHRQoL through different pathways.     

Periodontal health among recent immigrants from Quara,rural Ethiopia and indications for periodontal health care

OBJECTIVES: To investigate periodontal status and oral hygiene practices among recent new immigrants from Quara, Ethiopia, with the aim to maintain and promote their periodontal health. METHODS: Periodontal status was recorded for a total of 487 participants using the Community Periodontal Index (CPI). Age was grouped into 13-17, 18-24, 25-34, 35-44, and 45-65 years, and its association with 'worst CPI' was tested. Information on oral hygiene behaviour was collected by interview. RESULTS: The percentage of subjects with calculus is most common in all age groups. Low levels of periodontal pockets in the presence of calculus and very low levels of deep pockets were detected. Differences in CPI scores among the various age groups were statistically significant (p<0.0001). Oral hygiene practice is rare among children in Ethiopia, but a considerable proportion (53%) immediately adopted the local common custom and started brushing their teeth in Israel. Among the adults, oral hygiene practice with chewing sticks was common. CONCLUSIONS: Periodontal health promotion of this population should be targeted towards the entire population by enhancement of self-care oral hygiene measures. Periodontal treatment of this population, especially scaling and root planing remains controversial. The presence of inferior oral hygiene and high levels of calculus, together with low levels of periodontal pathology, raises important thoughts regarding the natural history of periodontal disease development.     

Work stress and oral health-related quality of life among Indian information technology workers: an exploratory study

Objectives: To assess the relationships among work stress, oral health and oral health‐related quality of life (OHRQoL) in information technology (IT) professionals in south India. Methods: The study population consisted of 134 IT industry workers in four mid‐size IT companies in south India. A self‐administered questionnaire consisting of the eight‐item Oral Impact on Daily Performance (OIDP) scale and a 25‐item modified version of the original 167‐item Work Stress Questionnaire was given, following which an oral examination was carried out. Results: Mean ± standard deviation scores on the Work Stress Questionnaire, the decayed, missing and filled teeth (DMFT) index and the Community Periodontal Index of Treatment Needs (CPITN) for the sample population were 53.82 ± 15.07, 4.23 ± 3.47 and 1.81 ± 0.58, respectively. A comparison of clinical oral health status data against respondents’ work stress and OIDP scores showed that mean DMFT and CPITN scores were significantly greater among those who reported oral impact on their daily performance. However, although participants who reported oral problems had consistently higher work stress scores, the differences were statistically significant only for gingival bleeding and sensitive teeth. Multivariate analysis after controlling for age and sex showed that higher levels of work stress and periodontal disease were significant predictors for poor OHRQoL in the sample population. Conclusions: Work stress may be an important predictor for poor OHRQoL and hence requires to be studied in greater detail.     

Oral health status of homeless people in Hong Kong

The authors report on an oral health survey among Hong Kong Chinese homeless people. A total of 140 homeless men underwent clinical examination and were interviewed with a structured questionnaire. More than 90% had evidence of caries experience; most (75%) were related to untreated caries. The mean DMFT score was 9.0 (DT=3.2, MT=5.2. FT=0.6). Periodontal disease was highly prevalent, with 96% having periodontal pockets. The dental problems most frequently reported by the homeless were: bleeding gums or drifting teeth (62%), dental pain (52%) and tooth trauma (38%). More than 70% of the study's participants perceived a need for dental care. The population surveyed had poorer oral health compared to the general population. High levels of dental needs, both normative and perceived, were found. There is a need to provide more accessible and affordable oral health services to this group of people.     

Prevalence and severity of dental caries in 5- and 12-year old children in the Veneto Region (Italy)

OBJECTIVES: To evaluate the occurrence of dental caries among 5- and 12-year-old children in Northeastern Italy and to compare dental status between immigrants and native-born children. BASIC RESEARCH DESIGN AND PARTICIPANTS: A cross-sectional survey of 260 5-year-olds and 862 12-year-olds was carried out between October 2003 and May 2004. Dental caries were diagnosed at the caries into dentine (D3) threshold. Differences in dental health status were compared between immigrant and native-born children for both age groups. RESULTS: Among 5-year-old children, mean dmft was 1.45 (SD=2.69), SiC=4.31, 65.8% had no caries. Immigrant 5-year-olds (6.2%) scored more poorly than their Italian counterparts: mean dmft was 5.12 (vs. 1.21; p<0.001) and only 25.0% were caries free (vs. 68.4%; p<0.001). Among 12-year-olds, mean DMFT was 1.44 (SD=2.00), SiC=3.88, 55.1% had DMFT=0: 5.6% also had poorer dental status: mean DMFT was 3.23 (vs. 1.33; p<0.001), SiC=6.69 (vs. 3.66), and only 17.1% had DMFT 0 (vs. 56.8%). CONCLUSIONS: The prevalence of dental caries and care obtained for both age groups are similar to those of other industrialised countries. When our results for 12-year-olds were compared with those of two previous surveys (1984 and 1994), a major decline in the prevalence of dental caries was observed. Being immigrant was a strong determinant in caries occurrence.

Oral health survey in Haitian and Hamburg children aged 12–15

Abstract— Oral hygiene, dental caries and periodontal diseases were surveyed in 1743 children aged 12–15. Of these 879 of Black origin resided in Haiti (West Indies) and 864 of While origin in Hamburg (West Germany). Oral hygiene was assessed using the G reene & V ermillion 'sOHI-S, periodontal status using R amfjord 's PDI and M uhlemann 'S SBI and the caries rate using the DMFT and DMFS indices. Boys of all age groups showed significantly poorer oral hygiene than girls. In the Hamburg children the mean OHI-S was 1.28, in Haitians 1.14. Periodontal diseases showed equal prevalence in Haiti and Hamburg when expressed in PDI, namely 0.59, while SBI was slightly higher in the Haitians, namely 2.58 against 2.21 in the Hamburg children. Hamburg girls showed lower PDI and SBI scores than all boys and Haitian girls. Same degrees of OHI-S caused more severe periodontal diseases among Haitian than among German children. In general, scores of OHI-S, PDI and SBI increased with age except in Haitian girls, who showed a decrease. The DMFT and DMFS of the Haitian children averaged 3.65 and 4.80 respectively, and those of the Hamburg children 8.35 and 21.09.     

Dental caries and associated factors in Mexican schoolchildren aged 6–13 years

The objectives of the present study were to establish dental caries prevalence (percentage with caries) and experience in the primary and permanent dentition (dmft and DMFT) of 6 to 13-year-old schoolchildren in Campeche, Mexico, and to estimate the contributing roles of the likely risk indicators. A cross-sectional study was carried out in 1,644 children aged 6–13 years. Self-administered questionnaires obtained information on social, economic, behavioral, and demographic variables. The primary dentition of 1,309 children and the permanent dentition of 1,640 children were evaluated in the oral examinations. The main outcome measures were DMFT, dmft, and SiC indices. Data were modeled using logistic regression analysis. The overall caries prevalence was 77.4%, 73.6% in the primary dentition (61.6% in 6-year-olds), and 49.4% in the permanent dentition. The dmft and DMFT indices were 2.85±2.73 and 1.44±2.05, respectively (DMFT=3.11±2.62 in 12-year-olds). The SiC index was 6.05 at 12 years of age. Associated variables to dental caries in both dentitions were presence of enamel defects, presence of dental plaque, low socio-economic status, female sex, and older age. Mother's schooling was negatively associated (OR=0.95) with caries in primary dentition. Caries experience in the primary dentition (OR=6.02) was positively associated with caries in the permanent dentition. Dental caries status in these Mexican children was closer to the goals proposed by the WHO/FDI for 2000 than previous studies. This study has identified clinical, socio-economic, and behavioral determinants for dental caries in primary and permanent dentition on Mexican schoolchildren.     

Oral health in Hlabisa, KwaZulu/Natal--a rural school and community based survey

AIMS: To investigate rates of dental caries and periodontal disease, available dental services and resources and perceived needs in a rural South African community. DESIGN: A cross-sectional field study including situational analysis and focus group discussions. SETTING: KwaZulu/Natal, South Africa. PARTICIPANTS: A total of 520 children, adolescents and adults. METHODS: WHO caries scores and periodontal CPI score were determined through clinical examinations in five age groups, 5-6 years, 12 y, 15 y, 35-54 y, 55 y+. Focus groups included ten 15-year-old children and ten adults. RESULTS: Caries prevalences and (mean scores) were 5-6 y 64% (dmft 3.0), 12 y 24% (DMFT 0.4), 15 y 27% (DMFT 0.8), 35-54 69% (DFT 2.6) and 55 y+ 80% (DFT 2.7). Most caries was untreated and where present, treatment had been extraction. Dental caries rates were low and except for 5-6 y were within WHO targets for the year 2000. Periodontal disease prevalence was high but would respond to improved oral hygiene. Knowledge of oral health was rudimentary. CONCLUSIONS: A district-wide oral health promotion programme is required preceded by research to define effective health education messages. Access to simple but effective preventive and curative services would seem reasonable. In view of the lack of resources ART is suggested as caries treatment.     

Oral health status among children and adolescents in governmental and private schools of the Palestinian Territories

Background: Political conflicts in the Palestinian Territories (PT) have resulted in systematic deterioration of socio-economic conditions and health. The World Health Organization (WHO) has emphasised the negative impacts of social crisis on children’ oral health and quality of life. Objectives: To assess the prevalence and trends in dental caries and poor gingival health of schoolchildren in the PT through the scholastic years 1998/1999 to 2012/2013. Methods: This is a retrospective study. Prevalence data on dental caries of primary and permanent dentitions among children 6, 12 and 16 years of age were gathered from annual oral health reports of the School Dental Health Programme (SDHP)-Ministry of Health. Caries was recorded according to WHO methods and criteria. Decayed, missing and filled teeth indices for primary (dmft) and permanent (DMFT) teeth were calculated. Gingival health status was examined according to the Community Periodontal Index (scores 1 and 2). Statistical analysis used SPSS. Results: In 2012/2013, dental caries prevalence rates and the index scores among schoolchildren were as follows, respectively: 56.4% and 2.7 dmft at age 6; 42.0% and 1.4 DMFT at age 12; and 38.7% and 1.7 DMFT at age 16. For all age groups, the d/D-component of the caries indices was high. Trends of dental-caries prevalence, caries experience and gingival bleeding were fairly constant over time from 1998/1999. Conclusion: The SDHP was established in order to prevent and control oral diseases among schoolchildren in the PT. The Programme is fairly passive and the survey indicates an urgent need for reorientation of activities towards population-based prevention and health promotion. The application of the WHO Health Promoting Schools concept is highly recommended.Key words: Dental caries, gingival health, schoolchildren     

Oral health status of vulnerable groups in a village of the Central Highlands, southern Vietnam

Abstract:  Objectives:  Oral health status of vulnerable people in developing countries tends to be given lower priority than other health issues. Consequently, few studies have examined the oral health status of the poor and minorities in developing countries. We aim to examine the dental caries and periodontal status, and explore the risk indicators of dental caries between two ethnic groups in rural villages in southern Vietnam. Methods:  We examined the caries status and its risk indicators of 150 participants (Co-Ho minority and Kinh majority) living in a hamlet of Dangphuong village in Vietnam. We also assessed periodontal status of the participants aged 14 and over by Community Periodontal Index. Results:  We first found that dental caries were highly prevalent among both the Co-Ho minority and Kinh majority groups. Second, the higher numbers of dental caries among children with primary teeth were associated with a higher frequency of consuming sweets. Third, most people (87%) aged 14 and over had periodontal problems. Finally, the Kinh majority tended to have more dental caries than Co-Ho among people aged less than 30. Conclusion:  Oral health promotion should be considered as a part of the development programmes for vulnerable groups in Vietnam and other developing countries.     

Trends in oral health from childhood to early adulthood: a life course approach

Lu HX, Wong MCM, Lo ECM, McGrath C. Trends in oral health from childhood to early adulthood: a life course approach. Community Dent Oral Epidemiol 2011; 39: 352–360. © 2011 John Wiley & Sons A/S Abstract – Objectives: The aims of this study were to investigate trends in oral health in a cohort from late childhood through adolescence to early adulthood and to describe how the oral health of young adults was affected by their family sociodemographic characteristics, oral health status, and utilization of dental services during adolescence using life course approach. Methods: A cohort of 638 students was followed from late childhood (12 years old) through adolescence (15 years old) to early adulthood (18 years old) in Hong Kong. Dental examinations included the assessment of caries experience (DMFT score) and periodontal conditions (Community Periodontal Index, CPI) according to WHO criteria. Information on utilization of dental services, parental education attainment, and monthly household income was collected. Path analyses were performed to investigate oral health trends and the relationships between oral health (DMFT scores and highest CPI values) at age 18 years and the sociodemographic characteristics at age 12 years, oral health, and utilization of dental services during adolescence. Results: In 2004 and 2007, 395 (62%) and 324 (51%) subjects of the original sample were followed up when they reached the age of 15 and 18 years, respectively. The mean DMFT score gradually increased from 0.62 at age 12 to 1.52 at age 18 (P < 0.001). The proportion of subjects with calculus or shallow periodontal pockets (highest CPI score 2 or 3) also increased with age, from 58% at age 12 to 96% at age 18 (P < 0.001). The oral health trend path models showed that DMFT score and highest CPI value at age 18 years were positively associated with DMFT score and highest CPI value at younger ages (P < 0.05). Results of the two extended path models showed that household income had positive effect on the utilization of dental services (β > 0.29, P < 0.05) and the utilization of dental services had positive effect on DMFT score (β > 0.12, P < 0.05) but not for highest CPI value (P > 0.05). However, parental education attainment had no significant effect on either DMFT score or highest CPI value (P > 0.05). Conclusions: Oral health status had become worse from childhood to early adulthood in the study cohort. Economic circumstance of the subjects was found to be positively related to their utilization of dental services and through this contributed to the subjects’ caries experience. Oral health at younger ages was positively associated with succeeding oral health conditions.     

Prevalence and severity of dental caries in Libyan schoolchildren

Objectives: To assess prevalence and severity of dental caries, examine gender differences and assess the relationship of dental caries to socioeconomic status in a group of Libyan schoolchildren. Design and setting: A cross sectional observational study with cluster sampling within schools. Participants: A random sample of 791, 12‐year‐olds in 36 elementary public schools in Benghazi. Methods and main outcome measures: Dental caries was assessed using the DMFT and DMFS indices and WHO (1997) criteria. Information about socioeconomic status was collected through a dental health questionnaire. Results: The prevalence of dental caries was 57.8%. The mean DMFT and DMFS indices were 1.68 (SD ± 1.86) and 2.39 (SD ± 3.05) for all subjects and 2.90 (SD ± 1.56) and 4.14 (SD ± 2.97) for subjects with caries experience. Dental caries was more prevalent amongst girls (P = 0.002). There was a statistically significantly negative association between dental caries and the level of father’s education (P = 0.015). Conclusions: While dental caries prevalence in 12 year‐old Libyan children was high, the mean DMFT was low compared with other developing countries, but higher than the WHO goal for year 2020. The high level of untreated caries is a cause for concern, representing a high unmet treatment need.

Oral health status of adult population in Athens, Greece

An epidemiological study of dental caries, periodontal disease, and oral hygiene status in 736 employed adults aged 19-64 yr, was conducted in Athens, Greece. Dental caries was found to be prevalent, affecting almost the entire population examined. The mean DMFT values varied from 8.99 +/- 5.98 to 17.05 +/- 6.58 in different age groups. No difference was found in the mean DMFT values between sexes. Periodontal disease affected the 92.7% of the examined sample. The PI scores increased with age from 1.08 +/- 0.84 in the age group 19-24 yr to 3.7 +/- 1.84 in the age group 55-64 yr. Women showed lower PI index values than men but this difference was not statistically significant. The mean values of oral hygiene index varied from 1.60 +/- 1.05 to 1.97 +/- 1.42 in different age groups. Women presented better oral hygiene status than men and this difference was statistically significant for the younger age groups. Data concerning the toothbrushing frequency of the examined population are also presented. The results of this baseline study indicate that effective dental care is needed for the improvement of oral health status of the adult population.
