Ludwig's angina (LA) is a rapidly spreading cellulitis involving sublingual and submaxillary spaces. It arises most frequently from periapical periodontal infection of the mandibular molars. Two major complications LA are life-threatening upper airway obstruction infectious seeding mediastinum, which responsible for high mortality rate. Other include thrombophlebitis internal jugular vein, rupt...

Temporomandibular Joint (TMJ) ankylosis is the pathological osseous or fibrous fusion of the condyle of the mandible with the mandibular fossa of temporal bone. The etiology of TMJ ankylosis includes previous trauma, infection, arthritis and previous TMJ surgery. The Temporomandibular Joint (TMJ) ankylosis in children is rare and the exact causes remain unclear. Trauma is well known as the most...

Deep neck infections are associated with high morbidity rates in dentistry. Early diagnosis and intervention play an essential part in decreasing morbidity rates. The present study aims to report a case of odontogenic deep neck infection after third molar extraction. A 51-year-old male patient underwent extraction of the mandibular right third molar. Seven days later, the patient developed symp...

BACKGROUNDS The main problem with intraoral distraction of the mandible is the inability to achieve the three-dimensional mandibular correction as planned preoperatively. We developed a technique that allows spontaneous changes in the direction of mandibular elongation using an intraoral distractor. METHODS After mandibular osteotomy, the distractor is fixed to the distal segment of the mandi...

The mandibular canal transmits the inferior alveolar artery, vein and the inferior alveolar nerve. From an embryological perspective, there might be three inferior dental nerves innervating three groups of mandibular teeth. During rapid prenatal growth and remodeling in the ramus region there is spread of intramembranous ossification that eventually forms the mandibular canal. Occurrence of bif...

OBJECTIVES This paper proposes Han's ratio as an objective and quantitative comparative result obtained from pre and postoperative data in patients with a mandibular angle reduction. MATERIALS AND METHODS Thirty patients, 12 men and 18 women, who visited the Department of Oral and Maxillofacial Surgery with the chief complaints of skeletal mandibular prognathism and prominent mandibular angle...

Background and aims. One of the most common reasons forthe inferior alveolar nerve block anesthesia failure is the variation in mandibular foramen location. The aim of this study was to assess the location of mandibular foramen in children with mandibular retrognathism in comparison to children with normal skeletal occlusion in the mixed dentition. Materials and methods. One hundred and twenty ...

In the present study we have extended our previous findings about the effects of 10 minutes of passive mandibular extension in anesthetized Wistar rats. By prolonging the observation time to 3 hours, we showed that 10 minutes mandibular extension caused a significant reduction of the mean arterial blood pressure and heart rate respect to baseline values, which persisted up to 160 minutes after ...

mandibular defects may result from many conditions such as trauma, inflammatory diseases and tumors. there are rare cases reported in the literature that have demonstrated spontaneous bone regeneration after resection of the mandible. several factors such as age, preservation of the periosteum and genetics seem to influence spontaneous bone regeneration capacity in individuals. evaluation of th...

OBJECTIVES The facial bones are the most noticeable area in the human body, and facial injuries can cause significant functional, aesthetic, and psychological complications. Continuous study of the patterns of facial bone fractures and changes in trends is helpful in the prevention and treatment of maxillofacial fractures. The purpose of the current clinico-statistical study is to investigate t...
