Musculoaponeurotic architecture of the human masseter muscle: an in vivo ultrasonographic study of architectural changes during mandibular protrusion and lateral excursions.

Objective: The present study evaluated the in vivo musculoaponeurotic architecture of the superficial head (SH) of the masseter muscle (MM) of asymptomatic participants in excursive mandibular movements compared to the relaxed state as examined with ultrasonography. It was hypothesized that the mean fiber bundle length (FBL) and mean height of the aponeurosis (HA) of the laminae of the SH would differ significantly between the relaxed state and protrusion, ipsilateral excursion, and contralateral excursion.

Study Design: The MM was studied volumetrically in 12 female and 12 male asymptomatic participants bilaterally by using ultrasound imaging.

Prevalence of Bifid Mandibular Canal Amongst Indian Population: A Radiographic Study.

Background: Bifid mandibular canal (BMC) is a normal anatomical variation and has been less studied in the Indian population. This study was aimed at estimating the prevalence of BMC amongst Indian population.

Materials And Methods: The study sample comprised of 5800 digital orthopantomograms (OPGs) which were from four zones of India, i.

Qualitative and quantitative salivary changes and subjective oral dryness among patients with thyroid dysfunction.

Context: There is a paucity of literature regarding the effects of thyroid disorders on the oral cavity by influencing the salivary gland function.

Aims: This study aims to understand the qualitative and quantitative changes that thyroid disorder can cause in the salivary function.

Settings And Design:: After obtaining ethical clearance, 46 consecutive newly diagnosed thyroid dysfunction patients were enrolled in this cross-sectional study, along with 45 age-and sex-matched controls.

Comparison of Therapeutic Efficacy of Placental Extract with Dexamethasone and Hyaluronic Acid with Dexamethasone for Oral Submucous Fibrosis - A Retrospective Analysis.

Introduction: Oral Submucous Fibrosis (OSMF) is a potentially malignant disease of the oral cavity associated with betel nut chewing. The management of OSMF has been a subject of controversy and no definitive and widely accepted treatment is currently available for this condition.

Aim: To retrospectively evaluate the therapeutic efficacy of two treatment regimens (placental extract with dexamethasone and hyaluronic acid with dexamethasone) for the treatment of OSMF.
