The posterior palatal seal area has remained a subject of controversy as far as the marking of the anterior and posterior vibrating lines are concerned. Sometimes, the dentures are over extended or under extended which will either cause discomfort to the patient or will be less retentive to horizontal forces. Then in order to improve its retention the dentist has to perform various corrective measures. This technique describes the visual location of the anterior vibrating line by considering the difference in the colour and variations in the anatomic contour of the hard palate with the corresponding soft palate which is a very important step in the fabrication of a complete dentures or any removable prosthesis requiring post damming.Keywords

Aim
The study was aimed at evaluating the depth of cure and of a composite resin that was photo-activated using different methods.
Summary
A composite curing test fixture was filled with composite resin and photo-activation was performed using three methods: (1) Intermittent method (2) Continuous method (3) Exponential method. Depth of cure was measured at the unexposed bottom surface of the specimen using vicat polymer softening apparatus. The data was analyzed using Kruskal-Wallis test. Results showed that the depth of cure was highest with the intermittent method, followed by continuous method and the exponential method.

Prosthodontic management of child patients is often a challenge because the affected individuals are quite young. This is important that child patients to receive appropriate dental treatments at an early age for physiologic and psychologic reasons. The main objective of the prosthodontic treatment are to restore the deciduous arch, the appearance of the child and the peace of the mind of the patient and at the same time to educate the parents and child regarding regular dental care. This paper reviews the various prosthodontic treatment modalities in child patients.Keywords

Treatment of cleft lip and palate requires multidisciplinary management but the patient usually becomes a prosthodontist's responsibility, once all the surgical treatments have been attempted or discussed. The final onus lies on prosthodontist to compensate for remaining oral deficiencies.
This article describes and discusses the fabrication of Velopharyngeal obturator (using cast metal framework, heat cure acrylic resin and silicone soft liner) wherein an interim obturator was delivered before the final prosthesis was fabricated.
Impression technique for recording the defect required intraoral extension of loop tray in the mouth as reduced mouth opening contraindicated dual impression technique. Due the non availability of retentive features in the mouth i.e. short teeth, parallel walled extensive defect a cast metal framework was fabricated so as to achieve retention, stability and support for the prosthesis.
