Relationship between bite force, occlusal contact area, and three-dimensional facial soft tissue in dentofacial deformities.

PURPOSE: This study aimed to investigate three-dimensional facial soft tissue dimensions, maximum bite force (MBF), and occlusal contact area in patients with DFD. In addition, we analyzed the relationship between MBF and the three-dimensional facial measurements. METHODS: Thirty-two patients with skeletal Class III DFD and 20 patients with Class II DFD underwent a soft tissue evaluation using surface laser scanning, as well as MBF and occlusal contact area assessments. The DFD groups were compared with each other and with 25 healthy subjects. RESULTS: Significant morphological differences were found in the transversal, vertical, and anteroposterior dimensions between Class II DFD and Class III DFD. Both DFD groups presented an increased linear distance of chin height, which was strongly related with decreased MBF magnitude. The DFD groups exhibited lower MBF and occlusal contact area, with no significant differences between Class II and Class III DFD. CONCLUSION: The presence of DFD affected 3D measurements of facial soft tissue, causing variations beyond normal limits, lower MBF, and occlusal contact area in both Class II and Class III DFD patients. The vertical dimension might have influenced the lower MBF magnitude in the studied skeletal deformities.

Orofacial Myofunctional Evaluation Protocol for older people: validity, psychometric properties, and association with oral health and age.

PURPOSE: To develop a comprehensive assessment protocol for identifying, classifying and grading changes in stomatognathic system components and functions of older people, to determine its psychometric properties and verify its association with oral health and age. METHODS: The content validity of the Orofacial Myofunctional Evaluation with Scores for Elders protocol (OMES-Elders) was established based on the literature. The protocol contains three domains: appearance/posture, mobility, and functions of the stomatognathic system. Eighty-two healthy elder volunteers (mean age 69±7.24 years) were evaluated using the OMES-Elders. A test-screening for orofacial disorders (reference) was used to analyze the concurrent validity (correlation test), sensitivity, specificity and accuracy (Receiver Operating Characteristic Curve: ROC curve) of the OMES-Elders. The association of the OMES-Elders scores with the Oral Health Index (OHX) and age in the sample was tested. RESULTS: There was a significant correlation between the OMES-Elders and the reference test (p < 0.001). Reliability coefficients ranged from good (0.89) to excellent (0.99). The OMES-Elders protocol had a sensitivity of 82.9%, specificity of 83.3% and accuracy of 0.83. The scores of the protocol were significantly lower in individuals with worse oral health (OHX ≤ 61%), although individuals with adequate oral health (OHX ≥ 90%) also had myofunctional impairments. The predictors OHX and age explained, respectively, 33% and 30% of the variance in the OMES-Elders total score. CONCLUSION: As the first specific orofacial myofunctional evaluation of older people, the OMES-Elders protocol proved to be valid, reliable and its total score was associated with oral health and age.

Signs and symptoms of temporomandibular disorders in women and men.

INTRODUCTION: Women are more likely to present temporomandibular disorders (TMD); however, studies comparing genders in Brazilian samples are rare. PURPOSE: To analyze the proportion of men and women, as well as the association between gender and age, problem duration, and TMD symptoms in patients admitted to an university clinic for treatment. METHODS: Interview and assessment data of protocols from 1,000 patients diagnosed with TMD were collected and analyzed and then divided into two groups, male (n = 177) and female (n = 823). The exploratory analysis was based on contingency tables and χ2 test was carried out. Subsequently, the logistic regression model was used and the odds ratios (OR) concerning the evaluated comparisons were calculated. RESULTS: Females were more prevalent in the sample, and mean ages and TMD duration were similar between the groups, with higher occurrence in young adults (19 to 40 years old). The OR values showed an association between the female gender and the signs/symptoms of pain in the temporomandibular joint, pain in the facial muscles, neck and shoulders, headache, fatigue in the muscles of mastication, otologic symptoms, and dysphonia. Women had two times higher chances of presenting these symptoms than men. CONCLUSION: In the sample of Brazilian patients with TMD, the number of women who presented a higher prevalence of painful symptoms was greater, followed by otologic symptoms and complaints of dysphonia. The prevalence of joint noise was similar in both studied groups.

Analysis of tongue pressure in Brazilian young adults.

PURPOSE: To present the measures for tongue pressure in Brazilian young adults, considering specific tasks, and to verify the differences regarding gender and according to the tasks. METHODS: Fifty-one volunteers aged 18 to 28 years, of both genders with normal occlusion and without speech disorders were evaluated. We used the Iowa Oral Performance Instrument in the evaluation of tongue pressure (kilopascal) during specific tests of elevation, protrusion, swallowing, and lateralization, in addition to the endurance test (seconds). The analysis was conducted using analysis of variance, followed by the Tukey's multiple comparison test, adopting a 5% significance level. RESULTS: The values obtained for men and women in the tests were as follows: elevation, 63.94±12.92 and 50.27±15.29; protrusion, 60.22±13.62 and 44.30±12.95; swallowing, 33.94±12.06 and 34.27±13.25; lateralization on the right, 44.15±10.47 and 31.85±8.46; lateralization on the left, 43.15±10.22 and 29.55±8.91; and endurance test: 24.85±10.95 and 17.35±6.71, respectively. The values were higher in men compared with women for the protrusion and lateralization tasks. The measures of the protrusion and elevation tasks did not differ for men but were higher in both genders than those of the lateralization and the swallowing tests. There was no difference in lateralization according to side in both the genders. CONCLUSION: The measures for the tongue pressure in Brazilian young adults were determined by specific tasks. Gender influenced the pressure of the tongue values for the protrusion and lateralization tasks. Elevation and protrusion tasks measures were higher than those of the lateralization and swallowing tasks.

Temporomandibular disorders and parafunctional oral habits: an anamnestic study

OBJECTIVE: To assess the frequency and severity of the signs and symptoms of temporomandibular disorders (TMD), the frequency of parafunctional oral habits and the correlation between the variables by means of the patients' perception regarding their problem. METHODS: One hundred patients diagnosed with TMD, through a clinical examination of their masticatory system, answered the questions of a previously published protocol concerning the signs and symptoms most frequently reported in the literature. RESULTS: According to the results from the non parametric statistical analysis, the frequency for the following signs and symptoms was significant: Fatigue and muscle pain, joint sounds, tinnitus, ear fullness, headache, chewing impairment and difficulty to yawn (p<0.01) and otalgia (p<0.05). As to the parafunctional oral habits, there was a significant presence of teeth clenching during the day and night (p<0.01) and teeth grinding at night (p<0.05). The variable correlation analysis showed that there was a positive correlation between symptom frequency and severity; age was correlated with the presence of otalgia, cervical pain and teeth sensitivity, besides being correlated with muscle and joint pain severity. Habit frequency was negatively correlated with age. TMD duration was also positively correlated with the symptoms of tinnitus, ear fullness, muscle and joint pain. CONCLUSION: The study results showed that the anamnestic assessment using ProDTMMulti can predict the severity of the TMD case.

Correlação entre métodos de aleitamento, hábitos de sucção e comportamentos orofaciais / Correlation between feeding methods, non-nutritive sucking and orofacial behaviors

BACKGROUND: the development of oral motor control depends partially on motor and sensory experiences. AIM: to analyze the relationship between the duration of breastfeeding, artificial feeding and sucking habits, and of these parameters with the orofacial motor performance. METHOD: participants of this study were one hundred and seventy-six children aged 6 to 12 years. All subjects were submitted to an orofacial myofunctional clinical examination, using a protocol with scores, and parents/care takers were interviewed in respect to the feeding and sucking habits of their children. Correlations were calculated using the Spearman Test. RESULTS: in the studied sample, the mean duration of breastfeeding was of 10.30 months (ranging from zero to 60 months), of artificial feeding was of 44.12 months (zero to 122 months) and of sucking habits was of 39.32 months (0 to 144 months). There was a negative correlation of breastfeeding duration with artificial feeding duration and sucking habits duration (p < 0001). The duration of the artificial feeding was positively correlated to the duration of sucking habits (p < 0001). The duration of breastfeeding was positively correlated with the mobility of the tongue and jaw (p = 0.05). There was a negative correlation of the duration of artificial feeding and the duration of sucking habits with the performance in mastication and swallowing, respectively, as well as with the duration of both types of sucking with the performance in the diadochokinesia test (p = 0.05). CONCLUSION: the duration of natural breastfeeding presented a positive effect over the mobility of the orofacial structures. Deleterious effects of the prolonged duration of artificial feeding and sucking habits in the oral motor control were confirmed.

TEMA: o desenvolvimento do controle motor oral depende em parte das experiências sensoriais e motoras. OBJETIVO: analisar a relação entre a duração do aleitamento natural, artificial e da sucção e destas com o desempenho motor orofacial. MÉTODO: cento e setenta e seis crianças, de 6 a 12 anos de idade, passaram por avaliação miofuncional orofacial, empregando o protocolo com escores, e os responsáveis foram entrevistados a respeito do aleitamento e hábitos de sucção de suas crianças. As correlações foram calculadas pelo teste de Spearman. RESULTADOS: na amostra estudada, a média de duração do aleitamento natural foi de 10,30 meses (variando de zero a 60 meses), do aleitamento artificial 44,12 (zero a 122 meses) e dos hábitos de sucção de 39,32 meses (zero a 144 meses). Houve correlação negativa da duração do aleitamento natural com a duração do aleitamento artificial e a duração dos hábitos de sucção (p < 0,001). A maior duração do aleitamento artificial correspondeu à maior duração dos hábitos de sucção, apresentando, assim, correlação positiva (p < 0,001). A duração do aleitamento natural foi correlacionada positivamente com a mobilidade orofacial (p = 0,05). Houve correlação negativa da duração do aleitamento artificial e da duração dos hábitos de sucção com, respectivamente, o desempenho na mastigação e na deglutição, bem como da duração de ambos os tipos de sucção com a prova de diadococinesia (p = 0,05). CONCLUSÃO: a duração do aleitamento natural mostrou efeito positivo sobre a mobilidade das estruturas orofaciais. Os efeitos deletérios da duração dos hábitos de sucção no controle motor orofacial foram confirmados.

Mandibular movement range in children.

BACKGROUND: identification of the mandibular movement range is an important procedure in the evaluation of the stomatognathic system. However, there are few studies in children that focus on normal parameters or abnormalities. AIM: to determine the average range of mandibular movements in Brazilian children aged 6 to 12 years; to verify the difference between genders, in each age group, and between the different age groups: 6-8 years; 8.1-10 years; and 10.1-12 years. METHOD: participants of the study were 240 healthy children selected among regular students from local schools of São Paulo State. The maximum mandibular opening, lateral excursion and protrusive movements, and deviation of the medium line, if present, were measured using a digital caliper. Student T test, Analysis of variance and Tukey test were considered significant for p < 0.05. RESULTS: the mean values observed in the studied sample were: 44.51mm for maximum mandibular opening; 7.71mm for lateral excursion to the right; 7.92mm for lateral excursion to the left; 7.45mm for protrusive movements. No statistical difference was observed between genders. There was a gradual increase in the range of mandibular movements, with significant differences mainly between the ages of 6-8 years and 10.1-12 years. CONCLUSION: during childhood the range of mandibular movements increases. Age should be considered in this analysis for a greater precision in the diagnosis.

Limites de movimentos mandibulares em crianças / Mandibular movement range in children

TEMA: a determinação dos limites de movimentos mandibulares é um importante procedimento na avaliação do estado funcional do sistema estomatognático, porém poucos são os estudos que focalizam os parâmetros de normalidade ou desvios em crianças. Objetivos: definir as médias dos limites de movimentos mandibulares em crianças brasileiras de 6 a 12 anos de idade; verificar diferenças entre os gêneros, em cada faixa etária, e entre as faixas etária de 6 a 8 anos, 8:1 a 10 anos e 10:1 a 12 anos de idade. MÉTODO: participaram 240 crianças, escolares do interior do Estado de São Paulo. Com o auxílio de um paquímetro digital foram mensuradas a máxima abertura mandibular, a protrusão, a excursão lateral direita e esquerda e o desvio da linha média, quando presente. O teste T Student, a Análise de variância e o pós-teste Tukey foram considerados significantes para p < 0,05. RESULTADOS: as médias das medidas da amostra foram: máxima abertura mandibular 44,51 mm, excursão lateral direita 7,71mm, excursão lateral esquerda 7,92 mm e a protrusão 7,45 mm. Não houve diferença estatística entre os gêneros. Houve aumento gradual nos limites dos movimentos mandibulares com o aumento da faixa etária, com diferenças significantes principalmente entre as faixas etárias de 6 - 8 anos e 10:1-12 anos. CONCLUSÃO: durante a infância os limites de movimentos mandibulares aumentam e a idade deve ser considerada na análise desses dados para maior precisão no diagnóstico.

Relationship between age, percentage of consonants correct and speech rate.

BACKGROUND: There is a lack of information regarding the relationship between age, speech rate and speech performance. AIM: To analyze and to compare the performance of children according to age, Percentage of Consonants Correct (PCC) and speech rate, and to determine the relationship between these variables. METHOD: Participants of this study were two hundred children divided in three different age groups: 6:0 to 8:0 years (Group I), 8:1 to 10:0 years (Group II), and 10:1 to 12:6 years (Group III). The following tests were used: speech rate tasks, imitation and picture naming (ABFW-Language test for children) and the Percentage of Consonants Correct (PCC) was calculated. Statistical analysis was performed using ANOVA for inter-group analysis, followed by the Tukey Test. The coefficient of Pearson Correlation was used to analyze the relationship between age, speech rate and speech performance (PCC). RESULTS: There was a significant difference between the PCC and speech rate when comparing the three groups (p<0.001). Regarding speech rate test, using /pataka/ as a stimulus, there were significant differences between Group I and the two other groups (p<0.01). There was a significant and positive correlation between age, the PCC and speech rate (p<0.05). CONCLUSION: Speech performance, measured by the PCC, and speech rate increased according to age, resulting in significant differences between the three age groups. The increase of the PCC indexes and of speech rate were directly proportional.

Relações entre idade, porcentagem de consoantes corretas e velocidade de fala / Relationship between age, percentage of consoants correct and speech rate

TEMA: faltam informações a respeito da relação entre idade, velocidade de fala e desempenho na fala. OBJETIVO: analisar e comparar o desempenho de crianças, de acordo com a faixa etária, quanto ao índice de porcentagem de consoantes corretas (PCC) e medidas de velocidade de fala, bem como determinar a relação entre essas variáveis. MÉTODO: os participantes deste estudo foram duzentas crianças agrupadas em três faixas etárias: 6:0 a 8:0 anos (Grupo I), 8:1 a 10:0 anos (Grupo II); 10:1 a 12:6 anos (Grupo III). Foram aplicados testes de velocidade de fala, de nomeação de figuras e imitação de vocábulos (ABFW - Teste de Linguagem Infantil) e calculados os índices porcentagem de consoantes corretas (PCC). A análise de variância (ANOVA) foi utilizada para a comparação do desempenho dos grupos, seguida pelo teste de Tukey. Para analisar a relação entre idade, velocidade de fala e PCC foi utilizado o teste de correlação de Pearson. RESULTADOS: houve diferença significante entre os três grupos quanto ao PCC e a velocidade de fala (p < 0,001). De acordo com o teste de velocidade de fala usando o estímulo /pataka/, houve diferenças significantes entre o grupo I e os outros dois grupos (p < 0,01). Houve correlação positiva e significante entre idade, desempenho nas tarefas de PCC e velocidade de fala (p < 0,05). CONCLUSÃO: o desempenho na fala, medido pelo PCC, e a velocidade de fala aumentaram de acordo com a faixa etária, resultando em diferenças significantes entre os grupos. O aumento do PCC e da velocidade de fala foram diretamente proporcionais

Correlation between feeding methods, non-nutritive sucking and orofacial behaviors.

BACKGROUND: The development of oral motor control depends partially on motor and sensory experiences. AIM: To analyze the relationship between the duration of breastfeeding, artificial feeding and sucking habits, and of these parameters with the orofacial motor performance. METHOD: Participants of this study were one hundred and seventy-six children aged 6 to 12 years. All subjects were submitted to an orofacial myofunctional clinical examination, using a protocol with scores, and parents/care takers were interviewed in respect to the feeding and sucking habits of their children. Correlations were calculated using the Spearman Test. RESULTS: In the studied sample, the mean duration of breastfeeding was of 10.30 months (ranging from zero to 60 months), of artificial feeding was of 44.12 months (zero to 122 months) and of sucking habits was of 39.32 months (0 to 144 months). There was a negative correlation of breastfeeding duration with artificial feeding duration and sucking habits duration (p < 0001). The duration of the artificial feeding was positively correlated to the duration of sucking habits (p < 0001). The duration of breastfeeding was positively correlated with the mobility of the tongue and jaw (p = 0.05). There was a negative correlation of the duration of artificial feeding and the duration of sucking habits with the performance in mastication and swallowing, respectively, as well as with the duration of both types of sucking with the performance in the diadochokinesia test (p = 0.05). CONCLUSION: The duration of natural breastfeeding presented a positive effect over the mobility of the orofacial structures. Deleterious effects of the prolonged duration of artificial feeding and sucking habits in the oral motor control were confirmed.
