Título: Factors influencing eruption time of first deciduous tooth / Factores influyentes en el periodo de erupción del primer diente primario
Fonte: J. oral res. (Impresa);8(4):305-309, nov. 5, 2019. tab.
Idioma: en.
Resumo: Introduction: Deciduous teeth play an important role in proper growth. Tooth eruption is a complicated process in which different mechanisms are involved. Early or delayed tooth eruption depends on different factors, with the impact of some already established. There are apparent controversy regarding the effect of some factors on time of the first deciduous tooth eruption among the conducted studies. The current study aimed to evaluate factors affecting the time of the first deciduous tooth eruption. Materials and Methods: One hundred and sixty eligible infants referring to the healthcare centers of Tabriz, Iran, were randomly selected; the demographic data including weight and height at birth, head circumference, mother's age and level of education, birth rank in the family and type of feeding were recorded, in addition to the time of the first deciduous tooth eruption. Data were analyzed using SPSS version 21 by ANOVA and t test.Results: Out of 54.1% female and 45.9% male participating infants, 78.3% had normal weight at birth. Results showed a significant relationship between weight at birth and timing of the first deciduous tooth eruption, among the evaluated factors. Conclusions: Although no significant relationship was observed between gender, type of feeding, mother's level of education and birth rank in the family, and time of the first deciduous tooth eruption, there was a significant relationship between the weight at birth and the timing of the first deciduous tooth eruption. Infants with higher or lower abnormal weight at birth had delayed deciduous tooth eruption.

Introducción: los dientes primarios juegan un papel importante en el crecimiento adecuado. La erupción dental es un proceso complexo en el que intervienen diferentes mecanismos. La erupción temprana o tardía de los dientes depende de diferentes factores, con el impacto de algunos ya establecido. Existe controversia entre los estudios realizados con respecto al efecto de algunos factores que afectan la erupción del primero diente primario. El presente estudio tuvo como objetivo evaluar los factores que afectan el periodo de erupción del primero diente primario o temporal. Materiales y Métodos: Ciento sesenta bebés referidos a los centros de salud de Tabriz, Irán, fueron seleccionados al azar; Se registraron los datos demográficos, incluidos el peso y la estatura al nacer, la circunferencia de la cabeza, la edad y el nivel de educación de la madre, el rango de nacimiento en la familia y el tipo de alimentación, además del momento de la primera erupción del diente primario. Los datos fueron analizados por ANOVA y t-test utilizando SPSS versión 21. Resultados: de los lactantes participantes (54,1% femeninos, 45,9% masculinos) el 78,3% tenía peso normal al nacer. Entre los factores evaluados, los resultados mostraron una relación significativa entre el peso al nacer y el momento de la erupción del primero diente primario. Conclusiones: aunque no se observó una relación significativa entre sexo, tipo de alimentación, nivel de educación de la madre y rango de nacimiento en la familia, y el period de erupción del primero diente primario, hubo una relación significativa entre el peso al nacer y el momento de la primera erupción dental decidua. En los lactantes con peso anormal al nacer se había retrasado la primera erupción de los dientes primarios.

Título: Effectiveness of Two Types of Photostimulable Phosphor Plate Plastic Barrier Envelopes for Prevention of Microbiological Contamination
Fonte: Pesqui. bras. odontopediatria clín. integr;20:e5378, 2020. tab.
Idioma: en.
Resumo: Abstract Objective: To compare the effectiveness of two types of commercially available photostimulable phosphor plate (PSP) protective barrier envelopes to prevent microbiological contamination. Material and Methods: In this cross-sectional study, 80 barrier envelopes were tested in 40 volunteers. The PSP plates were placed individually in Asia Teb and Soredex protective barrier envelopes and were placed in the mouth for two minutes, similar to periapical films. The protective barrier envelopes were then removed under sterile conditions, and the sensors were placed on different culture media. The number of colonies on each plate was counted. Data were analyzed using SPSS via McNemar and Wilcoxon tests. Results: Bacterial growth was noted in 17.5% of PSPs with Soredex, and 32.5% of PSPs with Asia Teb barrier envelopes. Gram-positive bacilli were the most commonly isolated bacteria. The difference between the Asia Teb and Soredex barrier envelopes for the protection of microbiological contamination was not significant (p>0.05). Conclusion: The use of different types of protective barrier envelopes was not sufficient for prevention of microbiological contamination of PSP plates, and some adjunct modalities were required to decrease microbiological contamination of PSP plates.

Título: Effect of Glass Fiber Post Diameter on Fracture Resistance of Endodontically Treated Teeth
Fonte: Pesqui. bras. odontopediatria clín. integr;20:e5413, 2020. tab, graf.
Idioma: en.
Resumo: Abstract Objective: To determine the fracture resistance of endodontically treated teeth restored with three different diameters of glass fiber posts and metal-ceramic crowns. Material and Methods: Thirty human maxillary canines were selected and subjected to root canal therapy. The teeth were randomly divided into three groups of glass fiber posts with 1.4 mm diameter (Group I), 1.6 mm diameter (Group II), and 2.0 mm diameter (Group III). The teeth were restored with metal-ceramic crowns and subjected to the compressive load applied at 45º angle to the longitudinal axis until fracture. The mode of failure was determined. Data were analyzed using ANOVA, followed by Tukey's post hoc multiple comparisons test (p<0.05). Results: The mean fracture resistance of groups I, II and III was 574 ± 91.2 N, 617 ± 85.21 N and 467 ± 99.43 N, respectively. No significant difference was noted between groups I and II, while the fracture resistance was significantly different between groups I and III (p<0.05) and groups II and III (p<0.05). No case of post fracture alone occurred in any group. Conclusion: The diameter of glass fiber posts can affect the fracture resistance of teeth. Based on the results, increasing the diameter of the post up to 1.6 mm may increase the fracture resistance of root, although excessive diameters are not recommended.

Resumo: Abstract Objective: To identify the prevalence of Internet addiction (IA) and associated factors among Iranian medical students. Material and Methods: The cross-sectional survey was conducted on a random sample of 400 students. The self-administered questionnaire consisted of two sections: the first section was sociodemographic data, data about student's relations, and Internet use characteristics; the second part aimed at assessment of the level of IA using Young's 20-item scale for IA. Data analyzed in SPSS 20 at 0.05 significant level. Results: Considering their familiarity with the Internet, 80.3% stated personal experience and 12.3% individuals stated educational periods held outside the university. The most locations of using the Internet were dormitories (21.0%) and houses (43.5%). Concerning hours of Internet use, 45.2% used the Internet more than two hours per day. One hundred sixty-eight individuals (42.0%) stated that they used the Internet less than 15% for university activities. One hundred eighty-eight individuals (47.0%) used VPN and 75.5% were dissatisfied with Internet speed 61.2%. A total of 64.3% had a poor dependency on the Internet and the prevalence of IA was 3.5%. The mean score of IA questionnaire was 43.98 ± 15.92 from 125. The mean score of IA was higher in the male sex, but there was no significant correlation between sex and IA (p>0.05). There was not a significant correlation between the field of study and the year of entrance. Conclusion: The prevalence of Internet addiction among medical students was low. Identification of factors associated with IA can help in the planning of preventive programs to raise students' knowledge about the hazards IA.

Resumo: Abstract Objective: To investigate the impacts of toothache on the daily activities of children aged 5 to 9 years. Material and Methods: A cross-sectional analytical study was conducted among 465 children (220 boys and 245 girls) aged between 5-9 years, using the Child Dental Pain Questionnaire (Child-DPQ), in the city of Kerman. They were categorized into two groups based on the clinical status: (1) untreated dental caries and (2) no dental caries or treated dental caries. For data analysis, the Chi-square, Mann-Whitney test, multiple logistic regressions, Spearman's correlation coefficient and t-test were used. Results: Regarding the severity of pain, about 28.3% reported mild pain, 30.1% moderate pain, and 21.9% very severe pain. The prevalence of reported dental pain increased by increasing the number of reported dental visits and more strongly among those having dmft>1. Toothache in children caused to stop eating (73.3%) and to sleep (63.8.1%) and provoked a dental visit in more than 40%. Conclusion: The toothache stopped many children eating and sleeping and provoked a dental visit in more than 40%. Among the children under study, 55.9% had to miss school.

Resumo: Abstract Objective: To validate the ultrashort (5-item) Persian version of OHIP by investigating its psychometric properties. Material and Methods: Construct validity was assessed by examining the correlation between OHIP-5 scores and self-reported oral health status, judgment for dental treatment needs and the number of natural teeth. Reliability was calculated using Cronbach's alpha and corrected item-total correlation. Effect size (ES) and Standardized Response Mean (SRM) were calculated for the responsiveness of the scale and factor analysis was done by measuring Kaiser-Meyer-Olkin (KMO), Bartlett's sphericity test and scree plot. Results: In 430 subjects (mean age 41.56+/-11.35 years, 56% female) the correlations between OHIP-5 scores and mentioned items were significant (p<0.01) indicating sufficient construct validity. The reliability coefficient (Cronbach's alpha) of the OHIP-5 was above the recommended 0.7 thresholds (0.809) and considered well. For evaluation of responsiveness, the ES was measured to be 5.604 and the SRM was 1.5. Moreover, in the confirmatory factor analysis, the unidimensional model for OHIP5 approved by indices (KMO=0.81, p<0.001 for Bartlett sphericity). Conclusion: The Persian version of OHIP-5 is a precise, valid, reliable and unidimensional instrument for assessing oral health-related quality of life among the general adult population.

Resumo: Abstract Introduction Tonsillectomy is one of the most common surgeries in the head and neck worldwide. This operation is carried out by different methods, the most frequent of which are the cold dissection and bipolar electrocautery techniques. Objective This study was conducted to assess and compare postoperative morbidity between cold dissection and bipolar electrocautery. Methods This prospective randomized clinical trial was performed on 534 patients who underwent tonsillectomy in Vali-e-Asr Hospital of Birjand, east of Iran from October, 2013 to October, 2015. The patients were systematically selected for cold dissection technique or bipolar electrocautery technique groups. Time of surgery, amount of intraoperative blood loss, postoperative hemorrhage, the intensity of local pain 4 and 24 hours after operation and nausea and/or vomiting were recorded and compared in the two groups to decide which technique is better. The data were analyzed in SPSS software (ver-22). The p-value less than 0.5 was considered significant. Results In this study, 51.7% of the cold dissection technique patients and 50.6% of the bipolar electrocautery technique participants were male. Compared to the cold dissection technique, the average intraoperative blood loss was significantly lower (p < 0.001) in the bipolar electrocautery technique group, while the intensity of local pain 4 and 24 hours after the operation was significantly higher (p < 0.001). Other variables showed no significant differences between the two groups. Conclusion Based on the findings of the present investigation, the bipolar electrocautery technique is suggested for tonsillectomy in children, while the cold dissection technique is preferred for adult patients.

Resumo Introdução A tonsilectomia é uma das cirurgias mais comuns de cabeça e pescoço em todo o mundo. Essa cirurgia é feita por diferentes métodos, os mais frequentes são a dissecção a frio e por eletrocauterização bipolar. Objetivo Este estudo foi feito para avaliar e comparar a morbidade pós-operatória na dissecção a frio e eletrocauterização bipolar. Método Este ensaio clínico prospectivo e randomizado foi feito em 534 pacientes submetidos a tonsilectomia no Vali-e-Asr Hospital de Birjand, no leste do Irã, de outubro de 2013 a outubro de 2015. Os pacientes foram selecionados de forma sistemática para o grupo submetido à técnica de dissecção a frio ou para o grupo com uso da técnica de eletrocauterização bipolar. Para a avaliação acerca da melhor técnica, os seguintes parâmetros foram registrados e comparados entre os dois grupos: tempo de cirurgia, quantidade de perda sanguínea intraoperatória, hemorragia pós-operatória, intensidade da dor local 4 e 24 horas após a cirurgia e ocorrência de náuseas e/ou vômitos. Os dados foram analisados no software SPSS (versão 22). O valor de p inferior a 0,5 foi considerado significante. Resultados Neste estudo, 51,7% dos participantes do grupo técnica de dissecção a frio e 50,6% do grupo técnica de eletrocauterização bipolar eram do sexo masculino. No grupo operado pela técnica de eletrocauterização bipolar a média de perda sanguínea intraoperatória foi significantemente menor (p < 0,001) em comparação à técnica de dissecção a frio, enquanto a intensidade da dor local 4 e 24 horas após a cirurgia foi significativamente maior (p < 0,001). As outras variáveis não apresentaram diferenças significantes entre os dois grupos. Conclusão Com base nos achados da presente investigação, para a tonsilectomia em crianças sugere-se o uso da técnica de eletrocauterização bipolar, enquanto a técnica de dissecção a frio é recomendada para pacientes adultos.

Idioma: en.
Resumo: Abstract Background In the current study we aimed to find out the impact of cytokine-inducible Src homology 2 domain protein (CISH) gene polymorphisms on the risk of pulmonary tuberculosis (PTB) in a sample of Iranian population. Materials and methods Polymorphisms of CISH rs2239751, rs414171, and rs6768300 were determined in 200 PTB patients and 200 healthy subjects using T-ARMS-PCR or PCR-RFLP method. Results The results showed that rs414171 A>T genotypes significantly decreased the risk of PTB (OR = 0.16, 95% CI = 0.10–0.27, p < 0.0001, AT vs AA; OR = 0.31, 95% CI = 0.14–0.68, p < 0.0001, TT vs AA; OR = 0.19, 95% CI = 0.12–0.29, p < 0.0001, AT+TT vs AA; OR = 0.29, 95%CI = 0.20–0.42, p < 0.0001, T vs A). For rs6768300, the findings indicated that this variant decreased the risk of PTB (OR = 0.52, 95% CI = 0.33–0.82, p = 0.005, CG vs GG; OR = 0.57, 95% CI = 0.38–0.87, p = 0.012, C vs G). No significant association was observed between CISH rs2239751 polymorphism and risk/protection of PTB. Conclusion Our findings indicated that CISH rs414171 and rs6768300 variants might be associated with protection from PTB.
