Resumo: El anàlisis del espacio requiere una comparación entre el espacio disponible y el espacio necesario para la alineación de los dientes. El ampliamente usado análisis del espacio de Tanaka-Johnston es cuestionado cuando es aplicado a diferentes poblaciones. Por tanto el propósito de este estudio fue determinar el ancho mesiodistal de incisivos, caninos y premolares mandibulares y caninos y premolares maxilares, para validar el anàlisis de Tanaka-Johnston según el sexo en 100 estudiantes yemenitas comprendidos entre las edades de 12 a 16 años. Se encontró diferencias estadísticamente significativas en el ancho mesiodistal de caninos y premolares según el sexo, excepto para el segundo premolar maxilar. La ecuación de Tanaka-Johnston sobreestima el ancho mesiodistal de los segmentos bucales en esta población(AU)

In space-analysis it is necessary a comparison between the available space and the necessary space in teeth alignement. The well-used Tanaka-Jhonston space analysis is questioned when it is applied in different populations; thus, the aim of present study was to determine the mesiodistal width of mandibular incisives, canines and premolar and of maxillary canines and premolar to validate the Tanaka-Johnston analysis according to sex in 100 Yemeni students aged from 12 to 16. There were statistically significant differences in mesiodistal width of canines and premolars according sex, except for the second maxillary premolar. The Tanaka-Johnston equation overrates the mesiodistal width of oral segments in this population(AU)

Idioma: en.
Resumo: Background: Carotid artery calcification (CAC) is one of risk factors of cardiovascular disorders (CVDs). Digital panoramic radiographs can detect it. Aim of the study: This study aimed to determine the prevalence of CAC detected by digital panoramic radiographs in a sample of Yemeni dental patients. Materials and Methods: An observational and analytical cross-sectional study was used to investigate a convenience sample of 443 patients. These patients were interviewed face-to-face for their socio-demographic information and their medical background regarding CVDs and associated risk factors. The researchers for detection of CAC assessed the digital panoramic radiographs. Results: High income and middle-aged patients were risk factors of CVDs significantly associated with increased incidence of CAC (42 patients (9.5%) and 32 patients (7.2%), respectively). Patients with a previous medical consultation, previous medications and family history of CVDs revealed a significant higher prevalence of CAC (p=0.001). Conclusion: There was an increased prevalence of CAC detected on digital panoramic radiographs, as a risk factor of CVDs. CAC was more common in females than males.

Antecedentes: La calcificación de la arteria carótida (CAC) es uno de los factores de riesgo de enfermedades cardiovasculares (ECV). La CAC puede ser detectada por radiografías panorámicas digitales. Objetivo del estudio: Este estudio tuvo como objetivo determinar la prevalencia de CAC detectada por radiografías panorámicas digitales en una muestra de pacientes dentales yemeníes. Materiales y métodos: Se utilizó un estudio transversal observacional y analítico para investigar una muestra de conveniencia de 443 pacientes. Estos pacientes fueron entrevistados en persona para obtener su información sociodemográfica y sus antecedentes médicos con respecto a las ECV y los factores de riesgo asociados. Los investigadores evaluaron las radiografías panorámicas digitales para detectar CAC. Resultados: Los pacientes de ingresos altos y de mediana edad fueron factores de riesgo de ECV significativamente asociados con una mayor incidencia de CAC (42 pacientes (9,5%) y 32 pacientes (7,2%), respectivamente). Los pacientes con una consulta médica previa, medicamentos previos y antecedentes familiares de ECV revelaron una prevalencia significativamente mayor de CAC (p=0.001). Conclusión: Hubo una mayor prevalencia de CAC detectada en radiografías panorámicas digitales como factor de riesgo de ECV, y CAC fue más común en mujeres que en hombres.

Título: The prevalence of tooth wear among a group of yemeni adults / La prevalencia del desgaste dental entre un grupo de adultos yemeníes
Fonte: J. oral res. (Impresa);8(6):478-487, dic. 28, 2019. tab.
Idioma: en.
Resumo: This study aimed at investigating tooth wear prevalence and determining the associated factors among a group of Yemeni adults. It is a preliminary cross-sectional and analytical investigation conducted on 600 participants aged 20­50 years. The participants were purposively selected from two main cities (Sana'a and Aden) with an equal sample size and divided equally by gender. For administering a questionnaire, interviews were conducted with all participants before clinically examining them. Using the Tooth Wear Index (TWI), tooth wear was assessed. Data were analyzed using the chi-square test to identify the relationship between tooth wear and associated factors., Tooth wear was prevalent among 78.67% of the participants; of which 64.83% were in anterior teeth, 63.83% in posterior teeth, 74% in maxillary teeth, and approximately 74.5% in mandibular teeth. It also was 100% prevalent in the 31-40 and 41-50 age groups, while it was 67.2% in the 20-30 age group. This showed that tooth wear prevalence was significantly higher in the two oldest groups than in the youngest group (p<0.001). Moreover, khat chewing, location, highly frequent consumption of foods and high frequency of acidic drinks consumption were critical indicators of tooth wear. Besides, a low education level, smoking and a low socio-economic status were associated with tooth wear. Finally, the study revealed that tooth wear is highly prevalent among adults in two Yemeni cities, and socio-behavioral risk indicators such as khat chewing and cigarette smoking have a significantly association with tooth wear.

Este estudio tuvo como objetivo investigar la prevalencia del desgaste dental y determinar los factores asociados en un grupo de adultos yemeníes. Es una investigación preliminar analítica y transversal que se lleva a cabo en 600 participantes de entre 20 y 50 años. Los participantes fueron seleccionados a propósito de dos ciudades principales (Sana'a y Aden) con un tamaño de muestra igual y divididos por igual por género. Para administrar un cuestionario, se realizaron entrevistas con todos los participantes antes de examinarlos clínicamente. Usando el Índice de Desgaste Dental, se evaluó el desgaste dental. Los datos se analizaron utilizando la prueba de chi-cuadrado para identificar la relación entre el desgaste dental y los factores asociados. El degaste dental tuvo una prevalencia del 78,67% de los participantes; de los cuales 64.83% en dientes anteriores, 63.83% en dientes posteriores, 74% en dientes maxilares y aproximadamente 74.5% en dientes mandibulares. Fue 100% prevalente en los grupos de edad 31-40 y 41-50, mientras que la prevalencia fue 67.2% en el grupo de edad 20-30. Esto demostró que la prevalencia del desgaste dental fue significativamente mayor en los dos grupos de personas mayores que en el grupo más joven (p<0.001). Además, mascar khat, la ubicación, el consumo muy frecuente de alimentos y la alta frecuencia de bebidas ácidas fueron indicadores críticos del desgaste dental. Además, el bajo nivel educativo, el tabaquismo y el bajo nivel socioeconómico se asociaron con el degaste dental. Finalmente, el estudio reveló que el desgaste dental es altamente prevalente entre los adultos en dos ciudades yemeníes, y los indicadores de riesgo socioconductual como la masticación de khat y el tabaquismo tienen una asociación significativa con el desgaste dental.

Título: Management of temporomandibular joint ankylosis in yemeni children by metatarsal bone grafts
Fonte: J. oral res. (Impresa);6(8):216-221, ago. 2017. tab, ilus.
Idioma: en.
Resumo: Aim: This study aimed to evaluate temporomandibular joint reconstruction in Yemeni children with metatarsal bone graft after release of ankylosis. Methodology: Ten patients ≤12 years of age, comprising eight unilateral and two bilaterally TMJ ankylosis, were selected for this study. These patients underwent reconstruction with 10 non-vascularized metatarsal grafts. The reconstructed joints were then followed for an average of 1 year. Measures of opening, symmetry, and clinical symptoms relating to the reconstructed joints were assessed. Results: Mean pre-operative interincisal aperture was 8.2mm, and immediate post-operative aperture 23.4mm. At the end of the follow-up period, acceptable results were achieved in 8 out of 10 cases, with adequate mouth opening of 35.6mm in 8 out of 10 patients and overall interincisal aperture of 30.3mm. Re-ankylosis occurred in two bilaterally-treated patients at the end of follow-up. Subjectively, 80 percent of the patients rated their function as satisfactory and were able to occlude and masticate without any difficulty. Conclusion: Reconstruction of TMJ after release of ankylosis utilizing metatarsal bone graft shows a satisfactory interincisal aperture in 80 percent of patients.

Idioma: en.
Resumo: Objective: This study was conducted to investigate the relationship between dental development and cervical vertebral maturation stages in a group of Yemeni children and adolescents. Materials an Methods: The study included digital panoramic radiographs and lateral skull cephalograms obtained from 207 Yemeni subjects­122 females and 85 males aged between 8 to 18 years. Dental maturity was evaluated according to the method of Demirijian et al., calcification stages of the left mandibular canines, first and second premolars and second molars were assessed. Skeletal maturity was assessed by the cervical vertebral maturation (CVM) stages according to the method of Baccetti et al. Correlation between CVM and dental maturation was evaluated by Spearman rank-order correlation coefficient (SROCC). Results: CVM and dental calcification stages were highly correlated (p<0.001) in both genders, ranging from 0.686 to 0.873 for females and 0.787 to 0.871 for males. Calcification stages of the second molars showed the strongest correlation with CVM. Conclusion: Calcification stages of the second molar may be used as a reliable maturation indicator. Dental maturation may be applied to determine the skeletal maturity status of Yemeni children and adolescents.

Objetivo: Este estudio se realizó para investigar la relación entre el desarrollo dental y las etapas de maduración vertebral cervical en un grupo de niños y adolescentes yemeníes. Material y Métodos: El estudio incluyó radiografías panorámicas digitales y cefalogramas laterales del cráneo obtenidos de 207 sujetos yemeníes: 122 mujeres y 85 hombres de entre 8 y 18 años. La madurez dental se evaluó de acuerdo con el método de Demirijian et al. Se evaluaron las etapas de calcificación de los caninos mandibulares izquierdos, primer y segundo premolares y segundos molares. La madurez esquelética se evaluó mediante las etapas de maduración vertebral cervical (CVM) de acuerdo con el método de Baccetti et al. La correlación entre la CVM y la maduración dental se evaluó mediante el coeficiente de correlación de orden de rango de Spearman (SROCC). Resultado: Las etapas de CVM y calcificación dental estuvieron altamente correlacionadas (p<0.001) en ambos sexos, con un rango de 0.686 a 0.873 para las mujeres y 0.787 a 0.871 para los hombres. Las etapas de calcificación de los segundos molares mostraron la correlación más fuerte con CVM. Conclusión: las etapas de calcificación del segundo molar pueden usarse como un indicador de maduración confiable. La maduración dental puede aplicarse para determinar el estado de madurez esquelética de los niños y adolescentes yemeníes.

Fonte: J. oral res. (Impresa);8(4):343-350, nov. 5, 2019. tab, graf.
Idioma: en.
Resumo: Aim: the aim of the study was to assess the prevalence of impacted teeth and its association with sex and age among a sample of the Yemeni population. Materials and Methods: A cross sectional study design was employed. The study included 999 radiographical records of patients who had panoramic X- rays previously done. All radiographs were assessed for the number and type of impacted teeth, pathology-associated impaction, sex, age and location (mandible and/or maxilla). The collected data was analyzed using SPSS®version21 software. Results: The study sample comprised digital panoramic radiographs of Yemeni patients aged 17 to 54 years (mean 26.6 years). The present study found 542 patients (54.3%) presented with at least one impacted tooth. The 17 to 25 years age group of the study sample had the highest prevalence of tooth impaction (28.6%). Only 10 (1.0%) case presented pathologies associated with the impacted teeth. There was a significant difference in the number of male 203 (20.3%) and female 339 (33.9%) patients with impacted teeth (p=0.031). Impacted teeth occurred slightly more often in the mandible (42.8%) compared to the maxilla (42.4%). Conclusion: The prevalence of impacted teeth among a sample of Yemeni population was high. Third molars and canines were the most common impacted teeth. The prevalence of impacted teeth in females was higher than in males and it was higher in the mandible than in the maxilla, with the younger patients with a higher prevalence of impaction.

Objetivo: el objetivo del estudio fue evaluar la prevalencia de dientes impactados y su asociación con el sexo y la edad en una muestra de la población yemení. Material y Métodos: se empleó un diseño de estudio transversal. El estudio incluyó 999 registros radiográficos de pacientes con radiografías panorámicas realizadas previamente. Todas las radiografías fueron evaluadas en relación al número y tipo de dientes impactados, patología asociada a la impactación, sexo, edad y ubicación (mandíbula y/o maxilar). Los datos recopilados se analizaron utilizando el software SPSS® version 21. Resultados: La muestra del estudio comprendió radiografías panorámicas digitales de pacientes yemeníes entre 17 a 54 años (media 26,6 años). El presente estudio encontró que 542 pacientes (54,3%) presentaron al menos un diente impactado. El grupo de edad de 17 a 25 años de la muestra de estudio tuvo la mayor prevalencia de impactación dental (28,6%). Solo 10 casos (1,0%) presentaron patologías asociadas a los dientes impactados. Hubo una diferencia significativa en el número de pacientes masculinos 203 (20.3%) y femeninos 339 (33.9%) con dientes impactados (p=0.031). Los dientes impactados ocurrieron con un poco más de frecuencia en la mandíbula (42.8%) en comparación con el maxilar (42.4%). Conclusión: La prevalencia de dientes impactados entre una muestra de población yemení fue alta. Los terceros molares y caninos fueron los dientes más comúnmente impactados. La prevalencia de dientes impactados en las mujeres fue mayor que en los hombres y fue mayor en la mandíbula que en el maxilar, y los pacientes más jóvenes mostraron una mayor prevalencia de impactación.

Título: Perception and confidence levels among dental students and interns in performing various endodontic procedures / Niveles de percepción y confianza entre estudiantes de odontología y pasantes en la realización de diversos procedimientos de endodoncia
Fonte: J. oral res. (Impresa);8(3):185-195, jul. 31, 2019. tab.
Idioma: en.
Resumo: Aim: The present study aimed to collect information from senior students and new interns enrolled at the College of Dentistry, University of Science and Technology (UST), regarding their confidence levels in performing endodontic treatments. Materials and Methods: Anonymous surveys were distributed to 40 senior students and 37 new interns at UST, in Sana'a, Yemen. They were asked to indicate their self-confidence level using a Likert scoring system ranging from 1 and 5. Mann-Whitney U test and chi-squared test were used to determine statistical significance between the studied groups. Results: 37.5% of students and 35.1% of interns rated endodontic practice as difficult. Only 55% of students found that the number of treated cases were satisfactory, similar to that reported by interns (56.8%). There were no statistically significant differences between both groups regarding self-confidence levels for most endodontic procedures (p<0.05). Placing of a rubber dam, followed by managing inter-appointment flare-ups were procedures in which both groups reported the lowest confidence. On the other hand, both groups felt the lowest confidence in the treatment of maxillary followed by mandibular molars. Statistically significant differences were reported between the two groups for performing root canal treatments (RCT) (p< 0.05). Self-confidence levels on the management of most different indications showed no statistically significant differences between both groups (p>0.05) with exception to the management of irreversible pulpitis, necrotic pulp, asymptomatic apical periodontitis, chronic abscess, and traumatic cases, in which significant differences were noticed (p<0.05). Immature apices, root resorption, endodontic-periodontal (EP) lesions, trauma, symptomatic apical periodontitis and acute abscess were ranked as the cases in which both groups reported the lowest confidence. Canal blockage and ledge formation were the main mishaps encountered during practice among students and interns. Conclusion: Students and interns displayed neutral confidence in performing endodontic treatments.

Objetivo: El presente estudio tuvo como objetivo recopilar información de estudiantes de último año y nuevos pasantes inscritos en la Facultad de Odontología, Universidad de Ciencia y Tecnología (UST), con respecto a sus niveles de confianza en la realización de tratamientos de endodoncia. Materiales y métodos: se distribuyeron encuestas anónimas a 40 estudiantes de último año y 37 nuevos pasantes en UST, en Sana'a, Yemen. Se les pidió que indicaran su nivel de confianza en sí mismos utilizando un sistema de puntuación Likert que oscilaba entre 1 y 5. Se utilizaron la prueba U de Mann-Whitney y la prueba de ji al cuadrado para determinar la significación estadística entre los grupos estudiados. Resultados: el 37.5% de los estudiantes y el 35.1% de los pasantes calificaron la práctica de endodoncia como difícil. Solo el 55% de los estudiantes encontró que el número de casos tratados fue satisfactorio, similar al reportado por los pasantes (56.8%). No hubo diferencias estadísticamente significativas entre ambos grupos con respecto a los niveles de autoconfianza para la mayoría de los procedimientos de endodoncia (p<0.05). La colocación de una presa de goma, seguida de la gestión de brotes entre citas, fueron procedimientos en los que ambos grupos informaron la menor confianza. Por otro lado, ambos grupos sintieron la menor confianza en el tratamiento del maxilar seguido de los molares mandibulares. Se informaron diferencias estadísticamente significativas entre los dos grupos para realizar tratamientos de conducto radicular (ECA) (p<0.05). Los niveles de autoconfianza en el manejo de la mayoría de las indicaciones diferentes no mostraron diferencias estadísticamente significativas entre ambos grupos (p>0.05) con excepción del manejo de pulpitis irreversible, pulpa necrótica, periodontitis apical asintomática, absceso crónico y casos traumáticos, en los cuales se notaron diferencias (p<0.05). Los ápices inmaduros, la reabsorción radicular, las lesiones endodóncicas-periodontales (EP), los traumatismos, la periodontitis apical sintomática y el absceso agudo se clasificaron como los casos en que ambos grupos informaron la menor confianza. El bloqueo del canal y la formación de repisas fueron los principales percances encontrados durante la práctica entre estudiantes y pasantes. Conclusión: los estudiantes y los pasantes mostraron una confianza neutral en la realización de tratamientos de endodoncia.

Resumo: Objective: This cross-sectional school based study aimed to assess the reliability of Fishman and Nolla methods in predicting the chronological age for Yemeni children. Material and Methods: Orthopantomographs and left handwrist radiographs were taken for 358 Yemeni children (193 boys and 165 girls) 8 - 16 years. Skeletal age estimated by Fishman method and dental age estimated by Nolla method were compared to chronological age using SPSS version 21, statistical significance was predetermined at P < 0.05 , using Intraclass Correlation CoefficientICC and Wilcoxon signed rank test. Results: The mean chronological, skeletal and dental ages were 12.00 ± 2.25 years, 12.39 ± 1.65 years and 11.32 ± 2.65 years, respectively. Intraclass correlation coefficient showed strong correlation between chronological age and skeletal and dental ages. Wilcoxon test showed Fishman method significantly underestimated the chronological age by 0.44 ± 1.26 years in boys and non-significantly underestimated the chronological age by 0.02 ± 1.08 years in girls. Nolla method significantly underestimated the chronological age by 0.59 ± 1.28 years in boys and 0.78 ± 1.21 years in girls. Conclusions: Chronological age of Yemeni children is highly correlated to skeletal age estimated by Fishman method and dental age estimated by Nolla method. However, the two methods underestimate the chronological age of Yemeni children.(AU)

Objetivo: Este estudo transversal de base escolar teve como objetivo avaliar a confiabilidade dos métodos Fishman e Nolla na predição da idade cronológica em crianças iemenitas. Material e Métodos: Foram realizadas ortopantomografias e radiografias do punho esquerdo em 358 crianças iemenitas (193 meninos e 165 meninas) de 8 a 16 anos. A idade esquelética estimada pelo método Fishman e a idade odontológica estimada pelo método Nolla foram comparadas com a idade cronológica pelo, utilizando-se o programa SPSS versão 21; a significância estatística foi predeterminada em P < 0,05, pelo coeficiente de correlação intraclasseICC e pelo teste de Wilcoxon. Resultados: As idades cronológica, esquelética e odontológica média foram de 12,00 ± 2,25 anos, 12,39 ± 1,65 anos e 11,32 ± 2,65 anos, respectivamente. O coeficiente de correlação intraclasse mostrou forte correlação entre idade cronológica e idade esquelética e dentária. O teste de Wilcoxon mostrou que o método Fishman subestimou significativamente a idade cronológica em 0,44 ± 1,26 anos nos meninos e não subestimou significativamente a idade cronológica em 0,02 ± 1,08 anos nas meninas. O método Nolla subestimou significativamente a idade cronológica em 0,59 ± 1,28 anos nos meninos e 0,78 ± 1,21 anos nas meninas. Conclusões: A idade cronológica de crianças iemenitas está altamente correlacionada à idade esquelética estimada pelo método Fishman e à idade dentária estimada pelo método Nolla. No entanto, os dois métodos subestimam a idade cronológica das crianças iemenitas.(AU)

Resumo: Objective: Periodontal diseases are very common dental disease. Many risk factors may play significant role in the periodontal disease initiation and progression. This study was performed to evaluate the effects of khat chewing, smoking, age and gender on periodontal status among Yemeni adults. Material and Methods: This cross-sectional study was performed on 1231 patients attending the outpatient dental polyclinics of University of Science and Technology during the academic years 2017/2018. All completed sheets were collected throughout the year by the supervisors. Data cleaning, descriptive statistics, and inferential statistics were then performed. Results: Khat chewers were more frequent than non-chewers counterparts (60.7% vs. 39.3%). The prevalence of smoking was 25.5% (297 patients). Study results indicated that periodontitis is more associated with female gender and participants aged more than 35 years old. Results also showed that female and age older participants aged more than 35 years were significantly associated with gingival recession. Mean number of the teeth with gingival recession in male patients were higher than in females. Male gender and patients aged more than 35 years old were significantly associated with furcation involvement. Conclusion: The present study has shown females gender and age older than 35 seem to be risk factors of periodontal diseases. Males has more teeth affected by gingival recession and more furcation involvement (AU)

Objetivo: As doenças periodontais são patologias dentárias com alta prevalência. Diversos fatores de risco podem desempenhar papel significativo no início e progressão das doenças periodontais. Este estudo foi realizado para avaliar os efeitos da mastigação de khat, tabagismo, idade e gênero na condição periodontal de adultos iemenitas. Material e Métodos: Este estudo transversal foi realizado em 1231 pacientes atendidos nas policlínicas odontológicas ambulatoriais da Universidade de Ciência e Tecnologia durante os anos acadêmicos de 2017/2018 através de um questionário para coleta de dados préestabelecido. Todas os questionários preenchidos foram coletados ao longo do ano pelos supervisores. A apuração dos dados, estatística descritiva e estatística inferencial foram realizadas. Resultados: os mastigadores de Khat foram mais frequentes do que as não-mastigadores (60,7% vs. 39,3%). A prevalência de tabagismo foi de 25,5% (297 pacientes). Os resultados do estudo indicaram que a periodontite está mais associada ao gênero feminino e aos participantes com mais de 35 anos de idade. Os resultados também mostraram que participantes do gênero feminino e acima de 35 anos foram significativamente associadas à recessão gengival. O número médio de dentes com recessão gengival em pacientes do gênero masculino foi maior que no feminino. O gênero masculino e os pacientes com mais de 35 anos de idade foram significativamente associados ao envolvimento da furca. Conclusão: O presente estudo mostrou que o gênero feminino e a idade acima de 35 anos parecem ser fatores de risco para doenças periodontais. Pacientes do gênero masculino têm mais dentes afetados pela recessão gengival e mais envolvimento de furca.(AU)
