Idioma: es.
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)

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.

Título: Radiographic evaluation of root canal fillings in a selected Yemeni population: a retrospective study / Evaluación radiográfica de tratamientos de endodoncia realizados en una población Yemení: estudio retrospectivo
Fonte: J. oral res. (Impresa);5(4):146-152, June 2016. tab.
Idioma: en.
Resumo: Abstract: aim: to assess the root canal filling quality performed by general dental practitioners in Yemen through radiographic evaluation. Materials and Methods: Four hundred fifty-five digital panoramic radiographs were selected from the archive of the Dental Health Center in Sana'a, Yemen. The final sample consisted of 221 patients, 685 teeth, and 977 root canals. The criteria for overall radiographic adequacy of root canal fillings were defined as the presence of adequate length, density and taper, and absence of iatrogenic errors (ledges, transportations and perforations). Chi-square test was used to determine statistical significance between different parameters. Results: This study considered only radiographic criteria for evaluation of the root canal fillings. The percentage of root canal fillings with adequate length, density and taper was 30.8 percent, 29.6 percent and 20.7 percent, respectively. Considering the incidence of iatrogenic errors, perforations were present in 12 root canals (1.2 percent), while the presence of transportations was observed in 20 root canals (2.0 percent). However, ledges were no detected in any root canals. Conclusion: The root canal filling quality performed by general dental practitioners in Yemen is poor.

Resumen: objetivo: evaluar a través de la evaluación radiográfica la calidad de los tratamientos de endodoncia realizados por odontólogos generales en Yemen. Materiales y Métodos: Cuatrocientos cincuenta y cinco radiografías panorámicas digitales fueron seleccionados desde el archivo del Centro de Salud Dental en Sana'a, Yemen. La muestra final fue de 221 pacientes, 685 dientes y 977 endodoncias. Los criterios de adecuación radiográfica general de los tratamientos de endodoncia se definieron como la presencia de longitud adecuada, la densidad y la forma cónica y la ausencia de errores iatrogénicos (proyecciones, transportaciones y perforaciones). Se utilizó la prueba de chi-cuadrado para determinar la significación estadística entre los diferentes parámetros. Resultados: En este estudio se consideró sólo criterios radiológicos para la evaluación de las obturaciones del conducto radicular. El porcentaje de obturaciones del conducto radicular con la longitud adecuada, la densidad y la forma cónica fue del 30,8 por ciento, 29,6 por ciento y 20,7 por ciento, respectivamente. Teniendo en cuenta la incidencia de errores iatrogénicos, las perforaciones estaban presentes en 12 tratamientos (1,2 por ciento), mientras que se observó la presencia de transportaciones en 20 tratamientos (2,0 por ciento). Sin embargo, las proyecciones no fueron detectadas en ningún tratamiento. Conclusión: La calidad de los tratamientos de endodoncia realizados por dentistas generales de Yemen es pobre.

Título: Tongue lesions and anomalies in a sample of Yemeni dental patients: a cross-sectional study
Fonte: J. oral res. (Impresa);6(5):121-126, May 2017. tab.
Idioma: en.
Resumo: Background: Tongue examination helps considerably in diagnosing the underlying health state of the patient, especially in the cases of chronic diseases. The aim of this study is to determine the prevalence and association of tongue lesions with risk factors among Yemeni dental patients. Materials and methods: An oral medicine specialist examined all 713 patients attending the dental polyclinics at the University of Sciences and Technology (Sana'a, Yemen). The examination sheet was designed to include information related to patient characteristics, medical history, dental history, habits, and tongue lesions. Results: The prevalence of tongue lesions among the examined participants was 76.5 percent. The prevalence rate was 83.4 percent for males and 69.2 percent for females. Fissured tongue was the most common condition. Logistic regression analysis indicated that older age (p<0.001), gender (p=0.007), khat chewing (p<0.001), and smoking (p=0.001) were associated with fissured tongue; gender (p<0.001), khat chewing (p<0.001), and smoking (p<0.001) were associated with hairy tongue; and older age (p<0.001), khat chewing (p=0.001), and smoking (p=.021) were associated with coated tongue. Conclusion: The prevalence of tongue lesions among this sample of Yemeni population was 76.5 percent; fissured tongue and hairy tongue were the most prevalent lesions. Khat chewing, smoking, and older age were the associated risk factors for many of studied lesions and anomalies.

Título: Cross-sectional assessment of the periapical status as related to quality of root canal fillings and coronal restorations in a Yemeni population
Fonte: J. oral res. (Impresa);6(1):19-24, Jan. 2017. tab.
Idioma: en.
Resumo: Aim: the present study aimed to examine the influence of the quality of root canal fillings and coronal restorations on the prevalence of periapical lesions. Materials and Methods: Two hundred digital panoramic radiographs were obtained from the archive of Al‑HamziDental Center in Sana'a, Yemen. The final sample consisted of 120 radiographs, and 675 root filled teeth.The quality of root canal fillings was scored according to criteria of length, homogeneity and taper. Coronal status (type of restoration, signs of marginal leakage or decay) was also evaluated. The periapical status was categorized on the basis of presence or absence of radiographical signs of apical periodontitis. Chi-square test was used to determine statistical significance between different parameters. Results: We found that 93.6 percent of root filled teeth were associated with apical periodontitis. Only 9.2 percent of root filled teeth were found to have an acceptable standard of root canal fillings, of which 32.3 percent was also associated to signs of periapical disease. In roots with an unacceptable root canal filling, 95.4 percent had periapical disease. Teeth with good (14.4 percent) and poor (32.9 percent) intra-coronal restorations had apical periodontitis in 93.8 percent and 97.7 percent of cases, respectively. Crown restorations were present in 52.7 percent of root filled teeth, of which 91.0 percent were associated with periapical lesions. Conclusion: The poor technical quality of root canal fillings and coronal restorations is consistent with a high prevalence of apical periodontitis.
