Utility of Vibratory Stimulation for Reducing Intraoral Injection Pain.

Intraoral local anesthesia injection is often perceived as a painful and anxiety-causing dental procedure. Vibration stimulus is one of the nonpharmacologic methods used to reduce unwanted sensations of local anesthesia injection. This clinical study evaluated the effectiveness of a recently introduced vibratory stimulation device in intraoral local anesthesia administration.

Histologic evaluation of periodontal attachment apparatus following the insertion of a biodegradable copolymer barrier in humans.

The purpose of this study was to histologically evaluate the effectiveness of polylactide:polyglycolide 50:50 (DL-PLGA) as a barrier to prevent epithelial migration and to promote new connective tissue attachment. Mucoperiosteal flaps were performed on 17 human teeth. DL-PLGA membrane was placed over the roots and alveolar bone.

The histologic evaluation of new attachment in periodontally diseased human roots treated with tetracycline-hydrochloride and fibronectin.

The purpose of this study was to determine how the treatment of human tooth roots with tetracycline-HCl and fibronectin during periodontal surgery influences the attachment of the gingiva to the root surface. Mucoperiosteal flap surgery was performed on 22 teeth with periodontal disease. Teeth were assigned to three groups.

An evaluation of new attachment formation using a microfibrillar collagen barrier.

The objective of this study was to evaluate the effectiveness of microfibrillar collagen as a barrier to prevent epithelial migration and allow for guided tissue regeneration. Fourteen study teeth were selected. Mucoperiosteal flaps were elevated and roots were debrided and planed.
