Case-control study examining the impact of oral health problems on the quality of life of the families of preschoolers

Abstract The aim of this study was to evaluate the impact of dental caries, traumatic dental injuries (TDI), toothaches, and malocclusion on the oral health-related quality of life (OHRQoL) of the families of Brazilian preschool children. A population-based, matched case-control study involving 415 pre-schoolers aged 3-5 years was conducted. The case (impact on OHRQoL) and control groups (no impact on OHRQoL) were matched for age, gender, and family income at an 1:4 ratio. Impact on the OHRQoL of a family was assessed using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). Dental caries, TDI, and malocclusion were diagnosed by three calibrated dentists (Kappa: 0.85-0.90). Data analysis involved descriptive statistics and conditional logistic regression analysis (p ≤ 0.05; 95%CI). There were no differences between the cases and controls regarding age, gender, and family income (p > 0.05). The most frequent responses on the B-ECOHIS among cases were "felt guilty" (68.6%) and "been upset" (48.2%). The following variables were significantly associated with negative impacts on family OHRQoL (cases): caries severity (OR = 6.680; 95%CI = 2.731-16.349), a history of toothache (OR = 2.666; 95%CI = 1.492-4.765), parental rating of the child's oral health as poor (OR: 1.973; 95%CI = 1.072-3.634), and parent's/caregiver's age (OR = 2.936; 95%CI = 1.077-3.478). Anterior open bite was positively associated with OHRQoL (OR = 4.050; 95%CI = 1.333-12.314). Caries severity, a history of toothache, parental rating of the child's oral health as poor, and younger parents/caregivers were associated with impact on the OHRQoL of the families of preschoolers.

The anti-adherence effect of Lippia sidoides Cham: extract against microorganisms of dental biofilm / Efeito anti-aderente de Lippia sidoides: extrato contra microorganismos do biofilme dental

Most illnesses affecting the oral cavity are proven to have infectious origin. Several categories of chemical agents have been used in the chemical control of dental biofilm through strategies that aim at reducing bacterial adhesion and inhibiting the growth and the proliferation of microorganisms on the tooth surface. The use of plants in folk medicine and in Dentistry, as well as the spread of successful cases, has led to scientific exploration, resulting in chemical-pharmacological knowledge of thousands of plants. The present study aimed to evaluate the anti-adherence activity of Lippia sidoides Cham., comparing the results with those of 0.12% chlorhexidine by means of an in vitro simulation of dental biofilm. The studied bacterial strains were Streptococcus mutans, Streptococcus sanguinis and Lactobacillus casei, main responsible for the biofilm adherence. The studied extract was effective in inhibiting the adherence of Streptococcus mutans up to a concentration of 1:16, compared to Chlorhexidine. Lippia sidoides Cham extract showed anti-adherence effect on the major microorganisms responsible for dental biofilm consolidation.

É fato comprovado que a maior parte das doenças que acometem a cavidade bucal são de origem infecciosa. Várias categorias de agentes químicos têm sido utilizadas no controle químico do biofilme dental através de estratégias que visam a redução da adesão bacteriana, a inibição do crescimento, e a proliferação dos microrganismos na superfície do dente. A utilização das plantas pela medicina popular, seu uso na Odontologia e a divulgação dos êxitos, conduziram a exploração científica resultando no conhecimento químico-farmacológico de milhares de plantas. A presente pesquisa objetivou avaliar a atividade antiaderente da folha da Lippia sidoides Cham. comparando seus resultados com a Clorexidina 0,12%, através de uma simulação, in vitro, do biofilme dental. As linhagens bacterianas utilizadas na pesquisa foram o Streptococcus mutans, Streptococcus sanguinis, e o Lactobacillus casaram, principais responsáveis pela aderência do biofilme. O extrato estudado mostrou-se efetivo na inibição de aderência das bactérias ensaiadas até uma concentração de 1:16, sobre o Streptococcus mutans, sendo comparável à Clorexidina. O extrato da Lippia sidoides Cham. demonstrou efeito antiederente, sobre os principais microrganismos responsáveis pela consolidação do biofilme dental.

Developmental enamel defects and their impact on child oral health-related quality of life

This cross-sectional study assessed the impact of Developmental Enamel Defects (DED) on Child Oral Health-Related Quality of Life (COHRQoL). A sample of 944 11- to 14-year-old Brazilian schoolchildren was examined for the prevalence and severity of DED. The children completed the Child Perceptions Questionnaire (CPQ11-14), and socioeconomic status was also collected using a questionnaire. Poisson regression models were used to assess the association between DED and overall and domain-specific CPQ11-14 scores. The prevalence of DED was 19.7 percent. In general, children with DED did not indicate any decrease in self-perception. However, this condition was associated with an impact on the functional limitation domain. The presence of DED may cause negative impacts on a child's perception of oral health and on their daily performance.

Prevalence of parafunctional habits and temporomandibular dysfunction symptoms in patients attending a tertiary headache clinic / Prevalência de hábitos parafuncionais e de sintomas de disfunção temporomandibular em pacientes atendidos em um ambulatório terciário de cefaléias

OBJETIVE: To investigate the most prevalent forms of headache in a tertiary outpatient service, and to assess the frequency of associated parafunctional habits and temporomandibular dysfunction symptoms (TMD). METHOD: All new patients referred to the Headache Outpatient Service in UNIMES during 2008 were prospectively assessed by the neurologist and the dental surgeon. RESULTS: Eighty new patients were assessed; chronic migraine and episodic migraine without aura were the most prevalent conditions, accounting for 66.3 percent of all cases. There was significantly higher use of analgesics/days for the chronic migraine patients. The prevalence of parafunctional habits was 47.5 percent and the prevalence of TMD symptoms was 35 percent. CONCLUSION: The high prevalence of primary headaches, parafunctional habits and TMD symptoms and the inadequate use of analgesic drugs suggest that primary healthcare units need further training in the field of headache and orofacial pain.

OBJETIVO: Investigar as formas prevalentes de cefaléia em um ambulatório terciário e analisar a frequência de hábitos parafuncionais e de sintomas de disfunção temporomandibular (DTM) associados. MÉTODO: Todos os pacientes novos encaminhados ao Serviço de Cefaléias da UNIMES durante 2008 foram avaliados de forma prospectiva pelo neurologista e pelo cirurgião dentista. RESULTADOS: Oitenta pacientes novos foram avaliados; enxaqueca crônica e enxaqueca episódica sem aura foram as condições mais prevalentes, perfazendo 66,3 por cento de todos os casos. Houve uso significativamente alto de analgésicos/dias pelos pacientes com enxaqueca crônica. A prevalência de hábitos parafuncionais foi 47,5 por cento e a prevalência de sintomas de DTM foi 35 por cento. CONCLUSÃO: A alta prevalência de cefaléias primárias, hábitos parafuncionais, sintomas de DTM e o uso inadequado de drogas analgésicas sugerem que as unidades básicas de saúde necessitam maior treinamento no campo da cefaléia e da dor orofacial.
