RESUMO
Walnut is a common member of the family Juglandaceae. Recently, the evaluation of the phenolic content and antioxidant activity of the parts of walnut has received increased interest. Many reasons are responsible for teeth discolouration because teeth can absorb ingredients from tea, coffee, and food. Stains from these ingredients could stay in the porous enamel layer. Traditional whitening chemicals have some side effects, the most common of which is tooth sensitivity and mild or moderate gingival irritation. The aims of this comparative experimental study were to evaluate the whitening effect of Juglans regia dry husk extract and compare it with that of traditional prophylactic pumice. Forty human teeth were collected. Amongst these teeth, 20 were permanent, and the other 20 were primary. Each group was randomly divided into a study group (treated with dry husk extract) and a control group (treated with traditional pumice). Tooth colour was measured with Easy VitaShade Advanced 4.0, and the readings of lightness, chroma, and hue (a∗ represents the green to red axis and b∗ represents the blue to yellow axis) were documented for each tooth before and after polishing. A statistical analysis was performed using the Statistical Package for Social Science (version 22; Chicago, Illinois, USA). Data were analysed using Shapiro-Wilk, Wilcoxon sum rank, and Wilcoxon signed rank tests, and the level of significance was set to 0.05. A normality test was conducted using the Shapiro-Wilk test, and it showed that the colour variables were not normally distributed. With regard to tooth lightness, significant differences were observed in the primary and permanent teeth and Juglans regia exerted a much better whitening effect than pumice at p < 0.05. This study supports the use of Juglans regia dry husk extract in dentistry as a natural product with a whitening effect. It has utilisation potential in dentistry due to its beneficial properties and highly active components.
RESUMO
BACKGROUND: There are many types of oral bacteria, and they differ between healthy children and children with an oral cleft. The purpose of this study was to compare the level of Staphylococcus aureus and Escherichia coli in complete cleft infants with normal infants. MATERIALS AND METHODS: Fifty-two Iraqi infants had participated in this study (26 infants were with cleft and 26 infants were the control healthy group), the study group included 13 infants with class III Veau's palatal classification, and 13 with class IV Veau's palatal classification). All are aged from 1 day to 4 months. They were selected and submitted to a questionnaire and clinical examination and bacterial examination. Data description, analysis and presentation were performed using statistical package for social science (SPSS version 21). RESULTS: The counting and colonization of S. aureus and GV- ( E. coli ) were higher in cleft group than in control group.

Objective: To evaluate the interaction of the dental anxiety precedents at the first dental examination and the AB secretor status of blood groups (A, B, AB, and O) on dental caries experience and severity in a group of school children. Material and Methods: This is a cross-sectional study included 81 healthy children aged 6-8 years from primary schools in Baghdad; with negative previous dental visit. Dental anxiety represented by physiological measures was measured by pulse oximeter. Dental caries experience and severity was recorded. Unstimulated salivary samples were taken from the children to determine the salivary secretor status for AB blood type. Results: The anxiety was decreased as age increases; boys were more anxious than girls; and more anxious children were found in non-secretor group; Dental caries was higher in non-secretor anxious children all with non-significant difference. Conclusion: There is little evidence that the AB secretor status and anxiety to have influence on dental caries experience and severity, as there are many factors may interact to propagate the caries experience and severity.

Objetivo: Avaliar a interação dos precedentes da ansiedade odontológica no primeiro atendimento e o status secretor do grupo sanguíneo ABO (A, B, AB, and O) na experiência e severidade de carie dental em um grupo de crianças em fase escolar. Material e Métodos: Este estudo cruzado incluiu 81 crianças saudáveis, com 6-8 anos de idade de escola primária em Baghdad; sem atendimento odontológico prévio. A ansiedade odontológica representada por medidas fisiológicas foi avaliada pelo oxímetro de pulso. A experiência à cárie bem como a severidade foram registradas. Amostras de saliva não estimulada foram coletadas das crianças para se determinar o status secretor salivar para tipo sanguíneo AB. Resultados: A ansiedade diminuiu conforme a idade aumentava; meninos foram mais ansiosos do que as meninas; e crianças mais ansiosas foram encontradas no grupo não secretor. A cárie dental foi maior no grupo não secretor de crianças ansiosas sem diferença significante. Conclusão: Há uma pequena evidência de que o status secretor AB e ansiedade tem influência na experiência e na severidade da cárie dental, assim como há vários fatores que podem interagir para propagar a experiência de cárie e sua severidade.(AU)
