INTRODUCTION The purpose of this study was to determine the relationship between the length of the lingual frenulum and craniofacial morphology and test the hypothesis that skeletal Class III malocclusion is related to tongue-tie, in which the lingual frenulum is short and restricts the mobility of the tongue. METHODS The sample consisted of 50 skeletal Class I patients (0° < ANB angle < 4°),...

[Purpose] This study aimed to evaluate the anti-inflammatory and analgesic effects of intraoral application of low-level laser therapy (660 nm) to control pain, swelling and interincisal opening following the extraction of mandibular third molars. [Subjects and Methods] Ten patients underwent removal of lower third molars using the same surgical protocol and pharmacological approach. In the pos...

BACKGROUND Intra-articular adhesion (IA) is one of the important pathologic signs of intracapsular temporomandibular joint (TMJ) diseases, but this factor has been rarely described with respect to its arthroscopic characteristics and histology. The purpose of this study was to describe the incidence and distribution of IA in patients with internal derangement (ID) and to investigate the correla...

PURPOSE The aim of this study was to evaluate the response of patients with temporomandibular disorders to Botulinum toxin A (BTX-A) therapy. METHODS The 15 subjects enrolled in this uncontrolled study were diagnostically categorized and treated with 150 units of BTX-A. Both masseter muscles received 50 units each under eletromyographic (EMG) guidance. Similarly, both temporalis muscles were ...

OBJECTIVE Posttraumatic ankylosis of the TMJ can be caused by many different pathogenic mechanisms. Prosthetic alloplastic grafts and autogenous grafts are the options for surgical treatment. METHODS Seven patients were examined clinically and radiologically. Autogenous interpositioners were used for treatment of TMJ ankylosis. RESULTS No major complications were seen after surgery. Interin...

introduction: angle and internal position of lateral pterygoid muscle leads to contraction over two half of the mandible in maximum opening and protrusion position so it can affects impression prosthetic procedures. the aim of this study was to evaluate the mandibular flexure in two transverse and antro-posterior dimensions. methods: seventy edentulous patients at mashhad faculty of dentistry a...

introduction: the aim of this study was to assess the effect of low-level laser therapy (lllt) on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. methods: a prospective, randomized double-blind study was undertaken on 44 patients at the dental school, ahvaz jundishapur university of medical sciences, in 2015. a low-level laser was randomly applied on one of ...

PURPOSE This study was aimed to determine whether a short period of maxillomandibular fixation (MMF) followed by an arch bar splint wired to the lower jaw is a suitable alternative to conventional MMF for treatment of fractures of the mandibular tooth-bearing area. PATIENTS AND METHODS Thirty patients with mandibular fractures associated with no other facial fractures were selected. They were...

The 20 patients in this quasi-experimental investigation had internal temporomandibular joint dysfunction. Prior to the procedure, information on sound, maximum inter-incisor opening of mouth (MIO), and pain intensity (VAS) were acquired. Patients checked seven days three months after operation gather outcome information. To find out procedure's effectiveness, pre- post-procedural data compared...
