The inferior alveolar nerve (IAN) block is the most frequently used mandibular injection technique for achieving local anesthesia for restorative and surgical procedures. However, The IAN block does not always result in successful anesthesia, especially pulpal anesthesia. Lidocaine is used as a "standard" local anesthetic for the inferior alveolar nerve. Articaine recently joined Korean market as a form of dental cartridge. It has an advantage of superior diffusion through bony tissue. A variety of trial was performed to improve the success rate of inferior alveolar nerve block. In this review, the recent update related with inferior alveolar nerve block anesthesia will be discussed on the anatomical consideration, anesthetic agent, technique, and complications.

Distraction osteogenesis is a well-estabilished procedure of membraneous bone formation and has been used to correct craniofacial deformities in dentofacial orthopedic-surgery area for decades. In this articale, distraction osteogenesis is used for treatment of facial asymmetry. The patient underwent procedures to lengthen the mandibular ramus and body. After distraction, orthodontic treatment was done for ooclusal settling.

A 47-year-old man was referred to the operating room to treat a dentigenous cyst of the mandibular bone. Initial assessment of the airway was considered normal. However, after the induction of anesthesia, we could not intubate the patient due to severe distortion of the glottis. Fiberoptic bronchoscopy and video laryngoscopy were not effective. Intubation using a retrograde wire technique was successful. After the conclusion of surgery, the patient recovered without any complications. Subsequent magnetic resonance imaging of the patient's neck showed a $6{\times}4{\times}8.6cm$ heterogeneous T2 hyperintense, T1 isointense well-enhancing mass in the prestyloid parapharyngeal space. The patient was scheduled for excision of the mass. We planned awake intubation with fiberoptic bronchoscopy. The procedure was successful and the patient recovered without complications. Anesthetic induction can decrease the muscle tone of the airway and increase airway distortion. Therefore, careful airway assessment is necessary.

This is a case report of polyostotic fibrous dysplasia developed in the craniofacial region of 21 year old male patient, who had complained the buccolingual expansion of left mandibular body area, malocclusion and facial asymmetry. We could achieve satisfactory results by radical resection of the relatively well defined small lesion of mandible and by cosmetic bone shaving procedure on the widely dispersed and poorly defined lesions of cranium. But the persistent growth and recurrence of the lesions may produce loss of hearing, visual difficulties, facial paralysis and anosmia, and as it is a polyostotic type occured in the craniofacial region of male patient, the possibility of malignant degeneration should not be excluded completely and periodic recall and check up will be necessary.

This is an extermely rare disease and a case of tuberculous osteomyelitis of mandible in a 45-year-old woman was reported. The patient was visited for complaining slight facial swelling on left side and purulent discharge from extracted socket. Roentgenograhic examination of the mandible revealed bone destruction on left side of mandibular body. Destructive lesion was removed with saucerization and specimen from the involved soft tissue and bone were sent for microscopic examination. This case proved to be primary tuberculous osteomyelitis caused by the absence of primary focus. After 3 months follow-up check, we noticed good prognosis of bone and soft tissue healing.

Synovial chondromatosis is an uncommon disorder characterized by metaplastic formation of multiple cartilaginous and osteocartilaginous nodules within connective tissue of the synovial membrane of joints. Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is frequently found in the general skeleton, but is rare in the mandibular condyle. We experienced 2 patients with abnormal appearance of temporomandibular joint. Histologic diagnoses were not obtained, because surgery was unwarranted in view of the lack of symptoms and the benign differential diagnosis. We describes 2 cases that show the characteristics of both disease simultaneously.

Verrucous carcinoma is a distinctive form of low-grade squamous cell carcinoma. The tumor has an exophytic, cauliflower-like appearance, and usually occurs in males and tends to affect individuals over 60 years of age. It typically involves the oral cavity, larynx, esophagus and skin. Most intraoral cases involve the mandibular vestibule, the buccal mucosa and the hard palate. The cause is unknown, but most verrucous carcinomas arise from the oral mucosa in people who chronically use chewing tobacco or snuff. The treatment of oral verrucous carcinoma remains controversial. Whenever possible, surgically total excision and skin or mucosal grafting is recommended. After total excision of huge verrucous carcinoma,instead of dermal or mucosal grafting, we used artificial dermis silicone membrane. We had a good result without recurrence and present this case.

After stage-two surgery, the highest incidence of failure has been attributed to implant overload. However, the biomechanical factors cited inthe literature that contribute to implant overload, such as bone type, cuspal inclination, horizontal offset, maxillary compared to mandibular arch, the inclusion of natural teeth within the prosthesis, and occlusal harmony are superimposed on physiologic variations. Following two cases, including reduction of cuspal inclination and usage of modified incisal pin, showed a method of contouring occlusal surface for reduction of unpreditable implant overload.

It has recently been reported that long-standing post-traumatic open bite can be successfully corrected with botulinum toxin type A (BTX-A) injection into the anterior belly of the digastric muscle (ABDM). The report documented an individual with bilaterally symmetrical and otherwise unremarkable anterior digastric musculature. However, the existence of variant anterior digastric musculature is common and may complicate the management of anterior open bite with BTX-A injection. Screening for variant ABDM can be accomplished via ultrasound, computed tomography, and magnetic resonance imaging. Screening for variant ABDM should be performed prior to BTX-A injection in order to account for musculature that may exert undesired forces, such as inferolateral deviation, on the anterior mandible in patients with anterior open bite.

A 46-year-old man was referred to our hospital for treatment, complaining of swelling on the right mandibular molar region. Radiographic examination revealed a well defined multilocular radiolucent lesion with root resorption of right lower anteriors and molars. Following biopsy, a diagnosis of unicystic ameloblastoma of mural type was made and hemimandibulectomy was performed under general anesthesia. Histopathological examination of the surgical specimen exhibited a unicystic ameloblastoma of luminal, intraluminal, and mural type. Intraluminal proliferation was of plexiform pattern and mural proliferation showed unusual histopathological findings, which revealed follicular, acanthomatous areas coexisted with desmoplastic areas. This mural picture was similar to the so-called 'hybrid lesion of ameloblastoma', whose biological profile is not elicited due to the lack of adequate published reports. Two years follow up till date has not revealed any signs of recurrence.
