 Currently, patient increased esthetic demands have dramatically led to the rapid development of allceramic materials. The purpose of this article is to understand classification, mechanical and clinical aspects of all-ceramic systems in esthetic dentistry. To make a clear understanding, this review article classifies allceramic systems into four major categories based upon their major composition, which are feldspathic and glass-ceramic, alumina-based, and zirconia-based system. Even though all-ceramic restorations have been reported to be a successful treatment option for patients, some critical limitations have to be considered such as veneer fracture, broken of the connecter, and loss of retention. The selection of these materials requires basic knowledge regarding material properties and case selection. All-ceramic restoration can be an alternative treatment option for patients especially in esthetically demanding cases.

 Stenosis of the pulmonary artery is a condition where the pulmonary artery is subject to an abnormal constriction .Peripheral pulmonary artery stenosis may occur as an isolated event or in association with Alagille syndrome, Berardinelli-Seip congenital lipodystrophy type1, Costello syndrome, Keutel syndrome,  nasodigitoacoustic syndrome (Keipert syndrome), Noonan syndrome  or Williams syndrome. It should not be confused with a pulmonary valve stenosis, which is in the heart, but can have similar hemodynamic effects. Both stenosis of the pulmonary artery and pulmonary valve stenosis are causes of pulmonic stenosis. The presentation of such a case may be very misleading. The case that we present here is about a 37 year old Carribean female who presented with progressive increase in SOB.

 Aim: To determine the prevalence of oral habits and its association with certain parameters (age, gender, child rank in the family, mother education and feeding type and duration) and the effect of oral habits on the occlusion of primary dentition. Methods: A cross-sectional study throuPankaj Datta, gh questionnaire and clinical examination for 489 preschool Sudanese children 3-5 years old, from randomly selected kindergartens in Khartoum. Results: Prevalence of oral habits was found to be 30.3%. Thumb sucking was the most prevalent one. No significant associations were found between oral habits, age and gender. A significant association were found between oral habits and rank of the child in the family as well with mother education level and breast feeding (P<0.05). A higher prevalence of open bite, increased overjet, distal molar relation, Class II canine relation, and posterior cross bite were found among children with existing oral habits. Conclusion: Sudanese preschoolers had  high prevalence of oral habits and persistent of oral habits after the age of three years has side effect on the primary occlusion, so early recognition of oral habits and proper education program for parents and children are recommended to prevent and intercept the occurrence of malocclusion in the permanent dentition.
