Making an impression represents a critical step in processing and fitting of a dental prosthesis. The definite impression should be accurate to fabricate restoration with ideal marginal fit, internal fit, interproximal contacts and occlusal contacts.   The impression materials are used to register or reproduce the form and relations of the teeth and the surrounding oral tissues. Dimensional accuracy and stability are the primary requisites of an impression material. Accuracy of an impression depends on properties of impression materials like thermal contraction, polymerization shrinkage, presence of volatile by products, elastic recovery, bulk of material and impression technique used.  Read more>>>>>>>>>>>

Dimensional accuracy and stability are theprimary requisites of an impression material.   Accuracy of an impression depends on properties of impression materials like thermal contraction, polymerization shrinkage, presence of volatile by products, elastic recovery, bulk of material and impression technique used. Other factors which influence the accuracy of an impression are tray material, space between tray and tooth preparation, storage conditions, relaxation of stresses caused by the use of non-rigid trays, excessive seating pressure, too slow removal from the mouth or an impression removed befor...

Sexual violence is a widespread problem. When the word heinous crime falls upon your ears the first name which pops in our mind is rape. Undisputedly the most gruesome and heinous of all crimes against any women. Even since civilizations came into existence to curb the crime, administrators and law makers have tried relentlessly by making appropriate laws related to it, but in vain.

Many assaulters get less or no jail term due to less knowledgeof doctor which causes loss of evidence during physical, sexual examination of rape victim. Detecting sexual abuse requires a high index of suspicion and expertise. Odontologist should be aware that oral or dental injuries may be result of physical or sexual abuse that sometimes can be confirmed by laboratory findings. Moreover, injuries inflicted by one's mouth or teeth may leave clu...
