Título: Autopercepção das condições alimentares de idosos usuários de prótese dentária / Autoperception of food conditions of elderly dental prosthetic users
Fonte: CoDAS;31(3):e20180080, 2019. tab, graf.
Idioma: pt.
Resumo: RESUMO Objetivo Avaliar a autopercepção das condições alimentares de idosos usuários de prótese dentária, verificando sua interferência na alimentação. Método Participaram 60 idosos com idade entre 60 e 88 anos, usuários de prótese dentária total ou parcial, que frequentam assiduamente o Centro de Convivência Nair Ventorin Gurgacz - FAG em Cascavel, Paraná. Todos os indivíduos responderam a um questionário de identificação e ao protocolo Índice de Determinação da Saúde Bucal Geriátrica (GOHAI). Resultados Os idosos do estudo, maioria mulheres e usuários de prótese removível bimaxilar com mais de 30 anos, classificam sua alimentação como "boa" e não possuem preferência por consistência alimentar, embora frequentemente sintam dor ao mastigar os alimentos. A média pontuada no protocolo GOHAI foi classificada como "ruim" e o maior prejuízo dos idosos ocorreu no domínio físico, que engloba questões relacionadas à mastigação, deglutição e fala. Não foram constatadas relações entre o tempo de utilização da prótese dentária com a idade e os escores do GOHAI. Conclusão Embora os idosos raramente tenham queixa sobre o modo de se alimentar, referindo desconforto ou constrangimento, apresentam uma média abaixo do esperado no protocolo, indicando que, ainda que não relatem, muitas modificações podem estar acontecendo, gradativamente, e que soam como naturais, gerando prejuízos à qualidade de vida em alimentação do idoso.

ABSTRACT Purpose To evaluate the self-perception of the food conditions of elderly users of dental prosthesis, in order to verify the interference that dental prosthesis has in their feeding. Methods The present study counted with 60 elderly, participants of the Centro de Convivência Nair Ventorin Gurgacz (Community Center), aged between 60 and 88 years old. All participants answered to a questionnaire elaborated by the researchers and the Geriatric Oral Health Assessment Index (GOHAI). Results The elderly who participated in this study, mostly women, used a bimaxillary removable prosthesis for over 30 years; although they classified their nutrition as "good" and did not present preference for specific food consistency, they frequently felt pain while chewing. The average score of the GOHAI was 29.73, considered "low", the index dimension with worst score was physical function, that includes eating, speaking and swallowing. No relation was observed between time of use of dental prosthesis, age and the GOHAI scores. Conclusion The elderly rarely complaint about discomfort or embarrassment on feeding, however, they present an average lower than expected in the GOHAI index, which indicates that, although they do not report it, many deteriorations, that seem to be natural may be happening and may be the cause of worst quality of life.

Título: Impact of mandibular conventional denture and overdenture on quality of life and masticatory efficiency
Fonte: Braz. oral res. (Online);30(1):e102, 2016. tab, graf.
Idioma: en.
Resumo: Abstract The aim of this non-randomized controlled clinical trial was to evaluate the oral health-related quality of life and masticatory efficiency of patients rehabilitated with mandibular two-implant overdentures with immediate loading or conventional dentures. Fifty completely edentulous patients wearing bimaxillary conventional dentures, for at least one year, were recruited. The patients were then assigned to either two treatment groups: mandibular overdentures supported by two implants with bar-clip system and a maxillary conventional denture (n = 25), and new maxillary and mandibular conventional complete dentures (n = 25). Masticatory efficiency and oral health-related quality of life were assessed before and 3 months after denture insertion. The Brazilian version of OHIP-Edent questionnaire was used to assess the oral health-related quality of life. Masticatory efficiency was evaluated with chewing capsules through a colorimetric method. The results revealed fewer oral health-related quality of life problems in patients wearing mandibular two-implant overdentures compared to the conventional dentures group. In addition, the implant overdenture group presented statistically significant improvement in masticatory efficiency (p = 0.001). There was no correlation between masticatory efficiency and OHIP in the implant group (p > 0.05), however a correlation was found in the conventional denture group (p < 0.05). Therefore, these short-term results suggest that mandibular overdenture retained by 2 implants with immediate loading combined with maxillary conventional dentures provide better masticatory efficiency and oral health-related quality of life than mandibular conventional dentures.

Título: Quality of life and mastication in denture wearers and cleft lip and palate adults
Fonte: Braz. oral res. (Online);32:e113, 2018. tab.
Idioma: en.
Resumo: Abstract The impact of oral rehabilitation on masticatory function and oral health-related quality of life (OHRQoL) may vary with the experience of the individual with tissue loss. Our hypothesis is that patient-centered outcomes vary among adults who have experienced large defects in the maxilla due to congenital or acquired conditions even after oral rehabilitation to restore aesthetics and function. This study compared OHRQoL, perceived masticatory ability, maximum bite force (MBF), and symptoms of pain and depression among subjects with acquired (edentulous maxilla) and congenital (cleft lip and palate) loss of oral tissues in the maxilla after dental treatment. A gender-matched sample (n = 60) of cleft lip and palate (CLP), maxillary denture wearers (DENT) and controls (CONT) was recruited. OHRQoL was assessed using OHIP-14. Chewing was evaluated through a masticatory ability questionnaire and by MBF. The RDC/TMD Axis II questionnaire was used to assess symptoms of pain and depression. Data were analyzed by Fisher's test, Kruskal Wallis test, and Spearman correlation coefficients. CLP showed higher OHIP-14 and depression scores than DENT and CONT (p < 0.05). Sub-analysis by OHIP-14 items (%FOVO) showed higher prevalence of psychological impact for CLP and of functional impacts for DENT. The number of foods difficult to chew, of food textures difficult to chew, and avoided foods were similar between CLP and DENT. OHIP-14, MBF, and depression scores showed significant correlation (p < 0.05). The results suggest that adults with treated CLP or maxillary DENT have chewing impairment and lower MBF than healthy subjects, with different psychological and functional impacts.

Título: Orofacial functions and quality of life in children with unilateral cleft lip and palate
Fonte: Braz. oral res. (Online);33:e0061, 2019. tab.
Idioma: en.
Projeto: National Council for Scientific and Technological Development.
Resumo: Abstract This study aimed to evaluate the orofacial functions and oral health-related quality of life (OHRQoL) of children with unilateral cleft lip and palate (UCLP). This case-control study included patients with UCLP matched by sex and age with controls (children without UCLP), resulting in the inclusion of a total of 108 eight- to ten-year-old children. Orofacial functions and OHRQoL were evaluated using the Nordic Orofacial Test-Screening (NOT-S) and the Child Perceptions Questionnaire (CPQ 8-1 0 ), respectively. Data normality was assessed by the Kolmogorov-Smirnov test. Differences and correlations in NOT-S and CPQ 8-1 0 scores between and within the groups were evaluated using Mann-Whitney and Spearman´s correlation tests, respectively. The distribution of NOT-S and global ratings of CPQ 8-1 0 for each group were assessed by Chi-squared/Fisher's Exact tests. The UCLP group had a higher NOT-S total and examination scores than the controls. Dysfunctions related to breathing, facial symmetry/expression, and speech were more frequent in the UCLP patients than in the controls. The UCLP group had higher scores on the social well-being domain than the controls. There was a significant difference between the groups in their ratings in regards to the extent to which their oral condition affected their life overall, with controls perceiving it as somewhat better than patients. In both groups, NOT-S total and interview scores were positively correlated with CPQ 8-1 0 total and domain scores. The NOT-S examination score was only significantly correlated with social domain scores in the control group. The presence of UCLP was associated with clinical signs of orofacial dysfunctions related to breathing, facial symmetry/expression, and speech. Children with UCLP reported more orofacial dysfunctions and negative impacts on social well-being than controls.

Título: Analysis of enamel and material wear by digital microscope: an in-vitro study
Fonte: Braz. oral res. (Online);33:e121, 2019. tab, graf.
Idioma: en.
Projeto: College of Dentistry Research Center.
Resumo: Abstract: The objective of the study was to analyze the surface area (SA) of the wear caused by simulated chewing on human enamel and opposing restorative material, namely: composite resin (CR), porcelain fused to metal (PFM), lithium disilicate (LD), or monolithic zirconia (MZr). Forty-eight premolars were selected as enamel specimens and divided randomly into 4 groups (n = 48; n =12) used as antagonists in chewing simulation (250,000 loading cycles) against one of the four selected test materials. Enamel and material specimens were scanned and evaluated under digital microscope, and wear SA (mm2) were recorded. Descriptive statistics, paired t-test, one-way ANOVA, and post-hoc Tukey-HSD tests were used for statistics (p < 0.05). The smallest and largest SA were exhibited by enamel against LD (0.80 mm2) and PFM (1.74 mm2), respectively. PFM (3.48 mm2) showed the largest SA and CR (2.28 mm2) showed the smallest SA. Paired t-test for SA values showed significant difference (p < 0.05) in all wear comparisons between materials and enamel antagonists. The wear of materials were greater than that of their respective enamel antagonists (p < 0.05). One-way ANOVA of the logarithmic means of wear SA revealed significant differences (P<0.05). Post-hoc Tukey test revealed significance for PFM (p < 0.05) with other materials. Wear of all test materials was greater compared to the wear of enamel antagonists. PFM and LD caused the largest and the smallest enamel wear, respectively. CR, LD, and MZr are more resistant than PFM to wear after simulated chewing against enamel.

Título: The influence of malocclusion, sucking habits and dental caries in the masticatory function of preschool children
Fonte: Braz. oral res. (Online);34:e059, 2020. tab.
Idioma: en.
Resumo: Abstract The aim of this study was to evaluate the association of malocclusion, nutritive and non-nutritive sucking habits and dental caries in the masticatory function of preschool children. A cross-sectional study was conducted with a sample of 384 children aged 3-5 years. A single examiner calibrated for oral clinical examinations performed all the evaluations (kappa > 0.82). Presence of malocclusion was recorded using Foster and Hamilton criteria. The number of masticatory units and of posterior teeth cavitated by dental caries was also recorded. The parents answered a questionnaire in the form of an interview, addressing questions about the child's nutritive and non-nutritive sucking habits. The masticatory function was evaluated using Optocal test material, and was based on the median particle size in the masticatory performance, on the swallowing threshold, and on the number of masticatory cycles during the swallowing threshold. Data analysis involved simple and multiple linear regression analyses, and the confidence level adopted was 95%. The sample consisted of 206 children in the malocclusion group and 178 in the non-malocclusion group. In the multiple regression analysis, the masticatory performance was associated with age (p = 0.025), bottle feeding (p = 0.004), presence of malocclusion (p = 0.048) and number of cavitated posterior teeth (p = 0.030). The swallowing threshold was associated with age (p = 0.025), bottle feeding (p = 0.001) and posterior malocclusion (p = 0.017). The number of masticatory cycles during the swallowing threshold was associated with the number of cavitated posterior teeth (p = 0.001). In conclusion, posterior malocclusion, bottle feeding and dental caries may interfere in the masticatory function of preschool children.

Título: Perceptions of rehabilitated patients with fixed partial dentures as to the temporary restoration
Fonte: Int. j interdiscip. dent. (Print);13(2):59-61, ago. 2020. tab.
Idioma: en.
Resumo: ABSTRACT: This study evaluated patients' perceptions regarding the installation of temporary fixed partial denture (TFPD). A questionnaire developed that addressed patients' perceptions about the temporary restorations, applied to patients after concluded their treatment. Responses were analyzed by descriptive statistics and contingency tables were constructed to statistically analyze the relationship between patients' perceptions of age, gender and type of prosthesis. We interviewed 28 patients (23 female; 5 male). In the results, 53.57% of the patients reported improvement in the chewing, 3.57% of the patients reported an improvement in speech, 21.43% of patients reported improvement in both aspects and another 21.43% of patients did not report functional improvements in speech and in chewing. Regarding dental pain, 89.28% did not present. In the hygienization aspect, 46.42% of the patients had difficulty, and 25% of the patients had bleeding gum. Finally, 89.28% of the patients reported that a TFPD made it possible to predict the final treatment outcome. No statistically significant difference was found when age (p = 0.86062) and gender (p=0.41225) were correlated. However, the type of prosthesis influenced patients' perceptions of TFPDs (p = 0.01254). It is concluded that TFPD is an important step in the treatment with fixed prosthesis.

Idioma: en.
Resumo: ABSTRACT Objective: To compare speech performance and levels of oral impairment between two types of lingual brackets. Methods: A parallel-group randomized controlled trial was carried out on patients with Class II, Division 1 malocclusion treated at the University of Hama School of Dentistry in Hama, Syria. A total of 46 participants (mean age: 22.3 ± 2.3 years) with maxillary dentoalveolar protrusion were randomly distributed into two groups with 23 patients each (1:1 allocation ratio). Either STb (Ormco) or 7th Generation (Ormco) lingual brackets were applied. Fricative sound/s/ spectrograms were analyzed directly before intervention (T0), one week following premolar extraction prior to bracket placement (T1), within 24 hours of bracket bonding (T2), one month after (T3), and three months after (T4) bracket placement. Patients′ acceptance was assessed by means of standardized questionnaires. Results: After bracket placement, significant deterioration in articulation was recorded at all assessment times in the 7th Generation group, and up to T3 in the STb group. Significant intergroup differences were detected at T2 and T3. No statistically significant differences were found between the two groups in reported tongue irritation levels, whereas chewing difficulty was significantly higher in the 7th Generation group one month after bracket placement. Conclusions: 7th Generation brackets have more interaction with sound production than STb ones. Although patients in both groups complained of some degree of oral impairment, STb appliances appeared to be more comfortable than the 7th Generation ones, particularly within the first month of treatment.

RESUMO Objetivo: comparar dois tipos de braquetes linguais, em termos de influência na fala e comprometimento da dicção. Métodos: foi realizado um estudo clínico randomizado com grupos paralelos, em pacientes portadores de má oclusão de Classe II, divisão 1, tratados na Faculdade de Odontologia da University of Hama, em Hama, na Síria. No total, 46 participantes (idade média de 22,3 ± 2,3 anos), com protrusão dentoalveolar maxilar foram aleatoriamente distribuídos em dois grupos com 23 pacientes cada (coeficiente de alocação = 1:1). Foram utilizados braquetes linguais STb (Ormco) ou braquetes linguais 7th Generation (Ormco). Foram analisados espectrogramas do som fricativo /s/ imediatamente antes da intervenção (T0), uma semana após a extração dos pré-molares previamente à colagem dos braquetes (T1), após 24 horas da colagem dos braquetes (T2), um mês depois (T3) e três meses depois (T4) da colagem dos braquetes. A aceitação dos pacientes foi avaliada por meio de questionários padronizados. Resultados: após a inserção dos braquetes, registrou-se deterioração significativa da dicção, em todos os intervalos de avaliação, no grupo com os braquetes 7th Generation; e até o intervalo T3, no grupo com braquetes STb. Foram identificadas diferenças intergrupos significativas em T2 e T3. Não foram encontradas diferenças estatisticamente significativas entre os dois grupos quanto aos níveis de irritação lingual relatados, ao passo que as dificuldades na mastigação foram significativamente maiores no grupo com braquetes 7th Generation um mês após serem inseridos. Conclusões: os braquetes 7th Generation apresentam maior interferência na dicção do que os braquetes STb. Embora os pacientes dos dois grupos tenham reclamado de um certo grau de comprometimento da dicção, os braquetes STb parecem ser mais confortáveis do que os braquetes 7th Generation, principalmente durante o primeiro mês de tratamento.

Título: Is there an association between skeletal asymmetry and tooth absence?
Fonte: Dental press j. orthod. (Impr.);21(4):73-79, July-Aug. 2016. tab, graf.
Idioma: en.
Resumo: ABSTRACT Introduction: Facial skeletal asymmetry is commonly found in humans and its main characteristic is menton deviation. The literature suggests that occlusal and masticatory problems arising from tooth absence could be related to the development of such asymmetries. Objective: The aim of this cross-sectional study was to estimate the prevalence of mandibular skeletal asymmetries and to investigate its association with posterior tooth absences. Methods: Tomographic images of 952 individuals aged from 18 to 75 years old were used. Asymmetry was the analyzed outcome, and it was categorized into three groups according to gnathion displacement in relation to the midsagittal plane (relative symmetry, moderate asymmetry, and severe asymmetry). Patients were sorted by the presence of all posterior teeth, unilateral posterior tooth absence, or bilateral posterior tooth absence. Chi-square test with a significance level of 5% was used to verify the association between posterior tooth absence and asymmetry. Results: Results show relative symmetry present in 55.3% of the sample, as well as the prevalence of 27.3% for moderate mandibular asymmetry and 17.4% for severe asymmetry. Moderate and severe mandibular asymmetries occurred in a higher proportion in patients with unilateral posterior tooth absence. However, there was no statistically significant difference between the analyzed groups (p = 0.691). Conclusions: In this study, mandibular asymmetries did not present any association with the absence of teeth on the posterior area of the arch.

RESUMO Introdução: a assimetria esquelética facial é comum em humanos, sendo o desvio do mento sua principal característica. É sugerido, na literatura, que problemas oclusais e mastigatórios advindos das ausências dentárias teriam relação com o desenvolvimento dessas assimetrias. Objetivo: o objetivo deste estudo transversal foi estimar a prevalência de assimetrias esqueléticas mandibulares e investigar sua associação com as ausências dentárias posteriores. Métodos: foram utilizadas imagens tomográficas de 952 indivíduos, com idade entre 18 e 75 anos. A assimetria foi o desfecho analisado, sendo categorizada em três grupos, de acordo com o desvio do gnátio em relação ao plano sagital mediano: simetria relativa, assimetria moderada e assimetria severa. Os indivíduos foram agrupados segundo a presença de todos os dentes posteriores, ausência dentária posterior unilateral ou ausência dentária posterior bilateral. Para verificar a associação entre a ausência dentária posterior e a assimetria, foi utilizado o teste Χ2, ao nível de significância de 5%. Resultados: os resultados mostraram que a simetria relativa esteve presente em 55,3% da amostra, bem como uma prevalência de 27,3% para a assimetria mandibular moderada e 17,4% para assimetria severa. As assimetrias mandibulares moderada e severa ocorreram em maior proporção nos indivíduos com ausência dentária posterior unilateral; entretanto, não houve diferença estatisticamente significativa entre os grupos (p = 0,691). Conclusões: nesse estudo, as assimetrias mandibulares em adultos não apresentaram associação com a ausência de dentes na região posterior da arcada dentária.

Título: Is the main goal of mastication achieved after orthodontic treatment? A prospective longitudinal study
Fonte: Dental press j. orthod. (Impr.);22(3):72-78, May-June 2017. tab.
Idioma: en.
Resumo: ABSTRACT Objective: To investigate the masticatory and swallowing performances in patients with malocclusions before and after orthodontic treatment, comparing them to an age- and gender-matched control group with normal occlusion. Methods: Twenty-three patients with malocclusions requiring orthodontic treatment were included in this prospective study. One month after appliance removal, seventeen patients completed a follow-up examination and the data were compared with those of a control group with thirty subjects with normal occlusion. Masticatory performance was determined by the median particle size for the Optocal Plus® test food after 15 chewing strokes, and three variables related to swallowing were assessed: a) time and b) number of strokes needed to prepare the test-food for swallowing, and c) median particle size of the crushed particles at the moment of swallowing. Results: At the baseline examination, the malocclusion group had a significantly lower masticatory performance and did not reach the particle size reduction at the moment of swallowing, when compared with the control group. After treatment, the masticatory performance significantly improved in the malocclusion group and the particle size reduction at swallowing reached the same level as in the control group. Conclusions: The present results showed that the correction of malocclusions with fixed appliances can objectively provide positive effects in both mastication and deglutition processes, reinforcing that besides aesthetic reasons, there are also functional indications for orthodontic treatment.

RESUMO Objetivo: investigar as performances mastigatória e de deglutição em pacientes com má oclusão, antes e após o tratamento ortodôntico, comparando-os com um grupo controle com oclusão normal, equiparado por idade e sexo. Métodos: vinte e três pacientes com má oclusão requerendo tratamento ortodôntico foram incluídos neste estudo prospectivo. Um mês após a remoção dos aparelhos, dezessete pacientes completaram os exames de acompanhamento, e seus dados foram comparados com aqueles de um grupo controle com trinta indivíduos com oclusão normal. A performance mastigatória foi determinada pelo tamanho mediano das partículas do alimento teste Optocal Plus® após 15 ciclos mastigatórios, e três variáveis relacionadas à deglutição foram avaliadas: a) tempo e b) número de ciclos necessários para preparar o alimento teste para deglutição, e c) tamanho mediano das partículas trituradas no momento da deglutição. Resultados: no exame inicial, o grupo com má oclusão apresentou uma menor performance mastigatória e não atingiu a redução do tamanho das partículas no momento da deglutição, quando comparado com o grupo controle. Após o tratamento, a performance mastigatória aumentou significativamente no grupo com má oclusão, e a redução do tamanho das partículas no momento da deglutição atingiu o mesmo nível do grupo controle. Conclusões: os resultados demonstraram que a correção das más oclusões com aparelhos fixos pode, objetivamente, proporcionar efeitos positivos nos processos de mastigação e deglutição, reforçando que, além de razões estéticas, existem também indicações funcionais para o tratamento ortodôntico.
