ABSTRACT
Metal free ceramic restorations have increased in demand due to their superior esthetics and more resemblance to the natural teeth, more so now that metal-free biocompatible options are preferred. Although porcelain fused to metal crowns are also used owing to less tooth structure loss in their preparation, the metal portion shows through the marginal area giving a blue-gray, cyanotic appearance to the tissue. Margins are one of the most important components in the success of a ceramic restoration. ssential prerequisites for the clinical success of an all ceramic restoration includes good esthetics, a high resistance to fracture and perfect marginal fit. A poor marginal design or one that is not prepared well may be a source of plaque accumulation, other than being esthetically unpleasing. Different marginal designs have been proposed and the most acceptable ones for all-ceramic restorations are either the rounded shoulder or the large chamfer margin. A major part of the current literature and research done on this subject falls into two broad categories that are affected by the type of marginal finish line - marginal fit and fracture resistance
ABSTRACT
Aglossia is a rare malformation resulting in the partial development or complete absence of the tongue. It is commonly associated with craniofacial and limb defects [Oromandibular Limb Hypogenesis Syndrome].The etiology is unknown and various theories have been proposed for this. The objective of presenting the case report and literature review is to discuss the clinical presentation, causative factors and possible management strategies of this rare malformation
ABSTRACT
For a long time, the practice of tooth brushing has been advocated as a highly effective method of maintaining oral hygiene and preventing dental caries, so much so that the efficacy of this practice has never really been questioned. However in the recent literature the greater role in the decline of dental caries has been attributed to the use of fluoridated tooth pastes. Is tooth brushing an effective technique modality for preventing dental caries by itself? Is tooth brushing without any usage of fluoridated tooth pastes effective in achieving a caries free dentition or is the role of the fluoridated toothpaste integral to achieve this? This article assesses the dental literature available to determine whether it is appropriate to rely on tooth brushing as caries preventive method. Tooth brushing cannot be completely disregarded as an oral hygiene measure. Following an efficient Tooth-brushing technique with appropriate frequency and Fluoridated Tooth paste can prevent tooth decay
