The Efficacy of Different Laser Applications on Dentin Sealing in Preventing Discoloration Induced by Mineral Trioxide Aggregate.

The aim of this in vitro study was to evaluate the effect of the pre-application of a dentin-bonding agent and the application of different lasers on the prevention of tooth discoloration caused by mineral trioxide aggregate (MTA) in the presence of blood. Sixty extracted human anterior teeth were selected, with root lengths standardized to 10 mm and root canals shaped using Gates-Glidden drills #3 to #5. The samples were divided into six groups ( = 10): Group 1 with no surface treatment and Groups 2 to 6 with Optibond universal adhesive and Neodymium yttrium aluminum garnet (Nd:YAG), Erbium yttrium aluminum garnet (Er:YAG), Erbium-chromium-yttrium-scandium-gallium-garnet (Er:Cr:YSGG), and diode laser applications, respectively.

Rehabilitation of Occlusal Vertical Dimension in a Patient with Acromegaly: A Clinical Report.

Acromegaly is a rare acquired disorder caused by excessive growth hormone production. Dentists play an important role in the diagnosis of this disorder because of intraoral and extraoral symptoms such as extreme growth of the mandible, enlargement of the maxilla, diastema between teeth, a tendency toward malocclusion, a wide and thick nose, a marked malar bone, and thick lips. The prosthetic treatment of these patients is challenging because growth in the condyles and rami can lead to the development of a severe class III jaw relationship.

Multidisciplinary management of a partially edentulous patient with oromandibular dystonia: A clinical report.

Oromandibular dystonia (OMD) is defined as a subset of movement disorders characterized by involuntary muscle contraction in different parts of the oromandibular region. This clinical report presents a multidisciplinary approach to the management of a patient with OMD. The involuntary movement of her mandible and tongue was improved with a mandibular custom occlusal device and maxillary modified removable complete denture together with botulinum toxin A injections.
