There are some surgeries after which a temporary cover for raw wounds is required to ensure healing. Some of those circumstances are loss of tissue due to burns, trauma, amputation, chronic ulcer, leprosy, and skin graft sites. Although the body initiates regeneration mechanisms, however the time taken for complete healing of wounds is unpredictable. Also, there is a tendency for long standing wounds to undergo infection and scarring. Oral mucosa is no exception to scarring and infection of wounds and there has always been a search for new materials that can be used for coverage of oral defects. Xenogenous collagen is one such grafting material. Over the years collagen implant solutions for a number of clinical applications include general surgery, burn surgery, neurosurgery, plastic and reconstructive surgery, oral surgery, and peripheral nerve and tendon surgery. This paper aims to focus on collagen as an effective option of wound closure in plastic and reconstructive surgery of the head and neck, especially after loss of soft tissue following resection of oral malignancies.

Aim This study was conducted to compare and evaluate the pain associated with administration of Nasopalatine blocks using a disposable insulin syringe and the conventional disposable 3 mL syringe. Materials and method Forty patients requiring intraalveolar extractions of maxillary central incisors were randomly assigned to two groups of 20 patients each; one (Group A) received the nasopalatine block with a standard 3mL syringe and the other (Group B) received the block with an insulin syringe. Patients were asked to rate the pain associated with the injection on a visual analog scale (VAS) and the results were analysed using a Chi Square Test. Results The mean VAS score for Group A and B was
