Orthodontic treatment needs in the western region of Saudi Arabia: a research report

BACKGROUND: Evaluation of self perceived and actual need for orthodontic treatment helps in planning orthodontic services and estimating the required resources and man power. In the present study, the perceptive need as evaluated by patients and the actual need to orthodontic treatment, as assessed by orthodontists, were evaluated at two types of dental practices in the city of Jeddah using the Index of Orthodontic Treatment Need (IOTN). METHODS: A consecutive sample of 743 adults seeking orthodontic treatment at two different types of dental practices in Jeddah; King Abdulaziz University, Faculty of Dentistry (KAAU) (Free treatment) and two private dental polyclinics (PDP) (Paid treatment), was examined for orthodontic treatment need using the dental health component (DHC) of the IOTN. The self-perceived need for orthodontic treatment was also determined using the aesthetic component (AC) of the IOTN. The IOTN score and the incidence of each variable were calculated statistically. AC and DHC categories were compared using the Chi-Square and a correlation between them was assessed using Spearman's correlation test. AC and DHC were also compared between the two types of dental practices using the Chi-Square. RESULTS: The results revealed that among the 743 patients studied, 60.6% expressed no or slight need for treatment, 23.3% expressed moderate to borderline need and only16.1% thought they needed orthodontic treatment. Comparing these estimates to professional judgments, only 15.2% conformed to little or no need for treatment, 13.2% were assessed as in borderline need and 71.6% were assessed as in need for treatment (p < 0.001). Spearman's correlation test proved no correlation (r = -.045) between the two components. Comparing the AC and the DHC between the KAAU group and PDP group showed significant differences between the two groups (p < 0.001). CONCLUSION: Patient's perception to orthodontic treatment does not always correlate with professional assessment. The IOTN is a valid screening tool that should be used in orthodontic clinics for better services especially, in health centers that provide free treatment

Perceived dental treatment need among older Tanzanian adults – a cross-sectional study

Need perceptions for dental care play a key role as to whether people in general will seek dental care. The aim was to assess the prevalence of perceived need of problem based dental care, dental check-ups and any type of dental care. Guided by the conceptual model of Wilson and Cleary, the relationship of perceived need for dental care with socio-demographic characteristics, clinically defined dental problems and self-reported oral health outcomes was investigated. Partial prosthetic treatment need was estimated using a socio-dental approach. A cross-sectional survey was conducted in Pwani region and in Dar es Salaam in 2004/2005. Information from interviews and clinical examination became available for 511 urban and 520 rural adults (mean age 62.9 yr). 51.7% (95% CI 46.2, 57.0) urban and 62.5 % (95% CI 53.1, 70.9) rural inhabitants confirmed need for dental check-up, 42.9% (95% CI 36.9, 48.9) urban and 52.7% (95% CI 44.5, 60.6) rural subjects confirmed need for problem oriented care and 38.4% (95% CI 32.4, 44.6) urban versus 49.6% (95% CI 41.8, 57.4) rural residents reported need for any type of dental care. Binary and ordinal multiple logistic regression analyses revealed that adults who reported bad oral health and broken teeth were more likely to perceive need for dental care across the three outcome measures than their counterparts. Socio-demographic factors and clinically defined problems had less impact. Based on a normative and an integrated socio-dental approach respectively 39.5% and 4.7% were in need for partial dentures. About half of the participants confirmed need for problem oriented care, dental check-ups and any type of dental care. Need perceptions were influenced by perceived oral health, clinically assessed oral problems and socio-demographic characteristics. Need estimates for partial denture was higher when based on clinical examination alone compared to an integrative socio-dental approach

Fatores associados à concordância entre autopercepção e avaliação clínica da necessidade de tratamento dentário em adultos do Brasil e de Minas Gerais

Resumo: O objetivo deste trabalho foi descrever a concordância entre a autopercepção e a avaliação clínica das necessidades de tratamento dentário em adultos e analisar os fatores associados. A amostra foi composta por indivíduos adultos que participaram do SBBrasil 2010 e do SBMinas Gerais 2012. A variável resposta do estudo corresponde à concordância entre a autopercepção e a avaliação clínica da necessidade de tratamento dentário. Regressão de Poisson múltipla foi utilizada para determinar os fatores associados ao desfecho. A concordância entre a autopercepção e a avaliação clínica foi de 78,8% no Brasil e 73,8% em Minas Gerais. Condições clínicas e autorrelatadas de saúde bucal que afetam a função e a qualidade de vida estiveram associadas à maior concordância, enquanto a visita recente ao dentista esteve associada à menor concordância. A identificação dos fatores associados pode propiciar o desenvolvimento de questionários que favoreçam a avaliação correta dos indivíduos sobre as suas necessidades de tratamento

Validade e utilidade da autopercepção de necessidade de tratamento odontológico por adultos e idosos

O objetivo deste trabalho foi determinar a validade das medidas de autopercepção como indicador de necessidades de tratamentos odontológicos em adultos e idosos. A amostra foi composta por indivíduos que participaram da Pesquisa Nacional de Saúde Bucal e da Pesquisa sobre as Condições de Saúde Bucal da População Mineira. A autopercepção da necessidade de tratamento dentário e de prótese total foi comparada com a necessidade determinada a partir do exame odontológico, considerado padrão-ouro. A qualidade das medidas foi avaliada por meio da sensibilidade, da especificidade e de valores preditivos. A sensibilidade variou de 51% a 90%, enquanto a especificidade ficou entre 56% e 90%. Os valores preditivos positivos foram de 11% a 95%, e os negativos, de 23% a 99%. A autopercepção de necessidade de tratamento dentário em adultos e de necessidade de próteses totais em idosos apresentou valores aceitáveis de validade. Por outro lado, a autopercepção da necessidade de tratamento por idosos e da necessidade de próteses totais por adultos não foi considerada útil devido a seu baixo desempenho
