Superolateral Dislocation of Bilateral Intact Mandibular Condyles: A Rare Case Series.

Background And Purpose: The dislocation of mandibular condyle is a clinical condition in which the head of condyle has been displaced out of the glenoid fossa. Complete dislocation of the mandibular condyle can occur in anterior, posterior, lateral and superior direction. Among these dislocations, bilateral superolateral dislocation of mandibular condyles is quite rare and often misdiagnosed.

Trigemino-Cardiac Reflex: A Phenomenon Neglected in Maxillofacial Surgery?

Background: Trigemino-cardiac reflex is a physiologic response of the body to pressure effects in the region of distribution of the trigeminal nerve. Oral and maxillofacial surgical procedures can induce the development of this reflex, which leads to significant changes in the heart rate and sinus rhythms. This study intends to evaluate the effects of this reflex in patients with facial fractures and its subsequent management.

The facial skeleton: Armor to the brain?

Background: With the development of urban setting worldwide, the major issue of concern is the increase in the mortality rate in the population due to road traffic accidents. The face, being the most exposed region is susceptible to injuries and maybe associated with injuries to the adjacent neuro-cranium. The literature has conflicting views on the relationship between facial fractures and head injuries with some authors opining that the facial skeleton cushions the brain while some other authors claim that the facial fractures act as indicators for head injuries.

Ophthalmological Evaluation by a Maxillofacial Surgeon and an Ophthalmologist in Assessing the Damage to the Orbital Contents in Midfacial Fractures: A Prospective Study.

Background And Purpose: Midfacial fractures may often be associated with injuries to the orbit which may lead to notable dysfunction of the visual apparatus, if not detected early after injury. The purpose of this study is to evaluate the associated ophthalmic injuries in mid-face trauma and to emphasize the need for understanding the ophthalmic signs and symptoms by an attending maxillofacial surgeon.

Patients And Methods: A total number of 60 clinically and radiographically proven subjects with midfacial fractures were considered in the study that underwent complete ophthalmological evaluation at initial presentation.

Evaluation of Antibacterial Efficacy of MTA with and without Additives Like Silver Zeolite and Chlorhexidine.

Introduction: Microorganisms, predominantly Enterococcus faecalis are found responsible in the progression of pulpal, periradicular diseases and in endodontic failures. Unsuccessful conventional treatment might necessitate the need for a surgical approach; where in retrograde restorative materials are used to seal the apex. Among the root end filling materials, Mineral Trioxide Aggregate (MTA) is considered biocompatible and is most commonly used in clinical applications but it has limited antibacterial activity.

Comparison of masticatory efficiency, patient satisfaction for single, two, and three implants supported overdenture in the same patient: A pilot study.

One Phase versus Two Phase Treatment in Mixed Dentition: A Critical Review.

The mixed dentition is the developmental period after the permanent first molars and incisors have erupted, and before the remaining deciduous teeth are lost. Phase I treatment is usually done early in this period. Mixed dentition treatment goals often focus on skeletal rather than dental correction.

Changes in cellular and molecular components of peripheral blood in patients with generalized aggressive periodontitis.

Aim: The association between periodontitis and systemic health is evident; however, until recently, there has been a lack of scientific evidence to define the relationship between aggressive periodontitis and systemic conditions. The aim of the present study was to evaluate the changes in the white blood cell count and levels of serum proteins in patients with generalized aggressive periodontitis (GAP) and to compare it with periodontally-healthy controls.

Methods: Patients with GAP (n = 60) and periodontally-healthy controls (n = 60) were recruited.

Role of prosthodontist in forensic odontology. A literature review.

Dental identification assumes a primary role in the identification of remains when postmortem changes, traumatic tissue injury, or lack of a fingerprint record invalidate the use of visual or fingerprint methods. The most common role of the forensic dentist is the identification of deceased individuals. Forensic identification based on assessment of prosthodontic appliances is assuming greater significance, as labeling of dentures and other prosthetic appliance could provide vital clues for patient identification.
