Multiple idiopathic cervical root resorptions: report of one case with 8 teeth involved successively.

Multiple idiopathic cervical root resorptions is a rare condition which is usually detected as an incidental radiographic finding. It involves more than 3 teeth in the same patient and the etiology remains elusive. Diagnosis and treatment of the defect is still challenging.

[Effect of dexmedetomidine on emergence agitation after oral and maxillofacial surgery].

Purpose: To evaluate the effect of dexmedetomidine on emergence agitation after oral and maxillofacial surgery.

Methods: Fifty five patients who went into recovery room after oral and maxillofacial surgery were randomly divided into 2 groups: dexmedetomidine group (n=28) and control group (n=27). Patients in dexmedetomidine group were assigned to receive intravenous dexmedetomidine at a dose of 0.

[Oxidative stress and susceptibility of periodontal disease].

Purpose: To investigate the relationship between dietary antioxidant status and susceptibility of periodontal disease in humans.

Methods: Fifty patients with moderate-to-sever periodontal disease and 50 subjects without periodontal disease were enrolled in this study. Food frequency questionnaire and 72-hour diet recall were conducted to study the dietary pattern and antioxidant nutrients intake in patients and healthy subjects.

Does platelet-rich plasma enhance the survival of grafted fat? An update review.

Autologous fat grafting enables repair and augmentation of soft tissues and is increasingly used in plastic and reconstructive surgery. The main limitation of fat grafting is unpredictable graft resorption. To obviate this disadvantage, several studies have searched for new ways of increasing the viability of the transplanted tissue.

Efficacy of pingyangmycin injection for the treatment of cervical epidermoid cysts.

Epidermoid cysts are benign lesions commonly seen in the head and neck region. Here, we describe the case of an epidermoid cyst in a 20-year-old man with a history of trauma presenting with a complaint of mass in the right cervical region. Upon closer examination, a 3cm long scar was noticed within the swollen region of the right submandibular area.

[Expression and clinical significance of serum interleukin-8 level in patients with oral squamous cell carcinoma].

Purpose: To explore the clinical significance of serum interleukin-8 (IL-8) level in patients with oral squamous cell carcinoma (OSCC).

Methods: Twenty-seven serum specimens pathologically confirmed as OSCC were tested,10 healthy serum specimens were used as control. The expression of serum IL-8 was measured by ELISA.

[Registration technology for mandibular angle osteotomy based on augmented reality].

Purpose: To establish an effective path to register the operative plan to the real model of mandible made by rapid prototyping (RP) technology.

Methods: Computerize tomography (CT) was performed on 20 patients to create 3D images, and computer aided operation planning information can be merged with the 3D images. Then dental cast was used to fix the signal which can be recognized by the software.

Intracystic injection of pingyangmycin (PYM) might be a more favorable option for treatment of oral and plunging ranulas.
