Parkinson's disease and oral health: A systematic review

OBJECTIVE

in patients with Parkinson's Disease (PD), oral health can be affected by motor and non-motor symptoms and/or medication use. Therefore, the aim was to systematically review the literature on oral health and associated factors of oral health in PD patients.

DESIGN

a literature search was performed from inception up to April 5th, 2023. Original studies that assessed oral health-related factors in PD patients and were written in English or Dutch, were included.

RESULTS

11276 articles were identified, of which 43 met the inclusion criteria (quality range poor-good). A higher prevalence of dental biofilm, bleeding/gingivitis, pocket depth (≥4 mm), tooth mobility, caries, and number of decayed missing filled teeth/surfaces was found in PD patients than in controls. However, no difference between both groups was found when analysing edentulism and wearing dentures. Poor oral health of PD patients was associated with a longer disease duration, higher disease severity, and more prescribed medications.

CONCLUSIONS

oral health of PD patients is worse than that of healthy individuals. It is associated with the duration and severity of PD and medication use. Therefore, we advise regular appointments with oral health care professionals, with an important focus on prevention.

Prevalence of plaque and dental decay in the first permanent molar in a school population of south Mexico City

Background

The first permanent molar is susceptible to acquire tooth decay since its eruption, due to its anatomy and because it has been exposed before other teeth.

Method

An observational, prolective, transversal and comparative study in 194 students, with an average age of 9.9 ± 1.8 years. The evaluation of the dentobacterial plate (DBP) was analyzed using the O'Leary index and the tooth decay experience with the DMFS (sum of decayed, missing, extracted and filling dental surfaces) and DMFT (sum of decayed, missing, extracted and filling per tooth) indexes.

Results

The prevalence of DBP in the first permanent molar was of 99.4% and tooth decay of 57.2%. The value of DMFT was 1.4 ± 1.4. The tooth decay experience was higher in children from 7.10 years old with a value of 2.2 ± 2.3, who are 7.9 times more likely to develop lesions than younger children (odds ratio: 8.9; 95% confidence interval: 4.1-19.5; p < 0.0001). We found an association between age and the values of the tooth decay experience indexes; even though these were weak in the case of DMF (r = 0.439), the model allowed to explain 19% of the association, and 22% for DMFT (r = 0.464).

Conclusions

Tooth decay develops rapidly in the first permanent molars; however, it does not receive the necessary care because it is usually unknown that it is a permanent tooth.

[Dental caries and early childhood development: a pilot study]

OBJECTIVE

To investigate the association between dental caries and early childhood development in 3-year-olds from Talca, Chile.

METHOD

A pilot study with a convenience sample of 3-year-olds from Talca (n = 39) who attend public healthcare centers. Child development was measured by the Psychomotor Development Index (PDI), a screening tool used nationally among pre-school children to assess language development, fine motor skills and coordination areas. Dental caries prevalence was evaluated by decayed, missing, filled teeth (DFMT) and decayed, missing, filled tooth surfaces (DFMS) ceo-d and ceo-s indexes. The children were divided into two groups according to the PDIscore: those with a score of 40 or more were considered developmentally normal (n = 32), and those with a score below 40 were considered as having impaired development (n = 7).

RESULTS

The severity of caries (DMFT) was negatively correlated with PDI (r = -0.82), and children with the lowest TEPSI score had the highest DFMT values. The average DMFT in children with normal development was 1.31, and 3.57 for those with impaired development.

CONCLUSION

This pilot study indicates that the severity of dental caries is correlated with early childhood development.

Relationship between caries, body mass index and social class in Spanish children

OBJECTIVE

To determine the association between caries, body mass index (BMI) and social class in child population of the Valencia region (Spain) at 6, 12 and 15 years, and study.

METHODS

In a cross sectional study of 1326 children aged 6 (n=488), 12 (n=409) and 15 years (n=433) who took part in the 2010 Oral Health Survey of the Valencia region, the ICDAS II criteria were employed for diagnosing and coding all the teeth examined. The quantitative BMI values on a continuous scale were grouped into 3 categories (normal weight, overweight, obese) based on a table adjusted for age and gender. The highest-ranking occupation of the parents was taken to indicate the social class of the child.

RESULTS

The mean BMI was 17.21 at 6 years, 21.39 at 12 years and 22.38 at 15 years. No significant differences in caries indexes (DMFT or dft) by degree of obesity stratified by social class were found in any of the age groups studied. There was no significant correlation between BMI and DMFT-dft in any of the age groups.

CONCLUSIONS

Obesity is not associated with dental caries in schoolchildren of this population.

Factors associated with early childhood caries in Chile

OBJECTIVE

To determine the prevalence of caries and identify the associated factors among children aged 2 and 4 years in southern Chile.

METHODS

A cross-sectional study was conducted in a random sample of 2,987 children. Dental examinations were performed in all participating children and a self-administered survey was administered to their primary caregivers. The statistical analysis included a zero inflated negative binomial regression model.

RESULTS

The prevalence of caries was 20.3% for 2-year-olds and 52.7% for 4-year-olds. The factors associated with caries included the following: living in the Bio-Bío region, PR 2 year-old: 1.65 (1.10-2.47), PR 4 year-old: 1.44 (1.18-1.75) and having a low socioeconomic position, PR 2 year-old: 5.39 (2.14-13.57), PR 4 year-old: 3.71 (2.68-5.13) or a medium socioeconomic position, PR 2 year-old: 2.79 (1.06-7.33), PR 4 year-old: 2.70 (1.92-3.79). In 4-year-olds, a high frequency of consuming sugary drinks at bedtime (PR: 1.30; 1.06-1.59), not brushing teeth daily (PR: 1.37; 1.18-1.60), and the presence of gingivitis (PR: 1.64; 1.28-2.09) were also associated with caries.

CONCLUSIONS

The high prevalence of caries in this young group is concerning. The factors associated with caries identified in this study could help in the design of preventive interventions at early ages.

[Fluoride content of bottled natural mineral waters in Spain and prevention of dental caries]

Objetivo

El propósito del estudio es conocer la concentración en flúor de las aguas minerales naturales comercializadas en España para poder prevenir la caries dental sin el riesgo de causar fluorosis dental.

Diseño

Estudio descriptivo y transversal a lo largo de 2012.

Emplazamiento

Aguas minerales naturales comercializadas en España.

Participantes

Tres muestras con fechas distintas de embotellado de 109 marcas de aguas minerales naturales (97 marcas españolas y 12 aguas importadas).

Medición principal

Determinación analítica por cromatografía iónica del contenido en fluoruro en el agua.

Resultados

La concentración mediana de fluoruro de las aguas minerales naturales españolas es de 0,22 (rango 0,00-4,16; rango intercuartil: 0,37). La gran mayoría (61 marcas, 62%) contenían menos de 0,30 mg/L. Hay 19 marcas que contienen más de 0,6 mg/L. Hay 19 marcas españolas que contienen más de 0,6 mg/L. En las 12 aguas minerales importadas, la mediana es de 0,35 (rango 0,10-1,21; rango intercuartil: 0,23). Sólo en 28 de las 109 marcas examinadas (25,6%) se especificaba el contenido de fluoruro en la etiqueta. Se observa una buena correlación entre las concentraciones indicadas y los valores analizados.

Conclusiones

Las concentraciones de fluoruro en las aguas minerales naturales comercializadas en España muestran una gran variabilidad. Dado el creciente consumo de las aguas minerales naturales en España, este tipo de información es de suma importancia para poder hacer una correcta utilización de flúor en la prevención primaria de la caries dental.
