Objective : The aim of this study was to investigate risk factor, precaution and treatment of aspirated foreign body during dental procedure. Material and Methods : Twenty cases of accidental aspiration of the foreign body, which removed by bronchoscopy at the Asan Medical Center between 2008 and 2012, were analyzed retrospectively. Results : Ten cases of accidental aspiration were occurred during dental procedure. Symtoms include cough(65%), dyspnea(50%), sputum(25%) and wheezing(25%). The most common location of foreign body was right bronchial tree(50%), left bronchial tree(45%) and carina(5%). Patients risk factors were chronic obstructive pulmonary disease, lung cancer, pulmonary tuberculosis, esophageal cancer and vegetative state. Conclusion : Accidental aspiration or swallowing of dental instrument or material is not uncommon accidents in dental practice. Most foreign bodies enter into gastrointestinal tract spontaneously. But aspiration into broncho-trachea can be more serious events and must be treated as an emergency situation. Prompt emergency treatment and removal of the foreign body is necessary to avoid complication. Dentists must have knowledge about the precaution and be ready to deal with foreign body aspiration during dental procedures.

Local pain management is the most critical aspect of patient care in dentistry. Local anesthesia is a reversible blockade of nerve conduction in an applied area that produces loss of sensation. The chemical agents used to produce local anesthesia stabilize neuronal membranes by inhibiting the ionic fluxes required for the propagation of neural impulses. Proper local anesthesia permits the dental surgeon to perform the necessary surgical procedure in a careful, gentle fashion that will be less stressful for both the operator and the patient. The improvements in agents for local anesthesia are probably the most significant advances that have occurred in dental science. Today's anesthetics are safe, effective, and can be administered with insignificant soft tissue damage and minimal concerns for allergic reactions. This article reviews the widely used local anesthetic agents for obtaining local anesthesia, and also discusses some frequently seen complications.

The purpose of this study was to find out the child's cooperation in the dental procedure. This study was undertaken in 69 children, 39 in male, and 30 in female, whose ages ranged from 2 to 5 years old. The response of young children and their mother during dental procedure was examined by questionaire and observation. The results were as follows: 1. With continued experience, the child's cooperation was improved, indicating desensitization to dental stress 2. The Higher the mother's educational level was, the higher the behavior of the child was. 3. The mother and child's anxiety were significantly related to the dental behavior of the children, but child's past history and predicted cooperation were not to be related. 4 The child's familiarity and early education were not significantly related to the dental behavior of the children.

Euccal fat pad is special fat tissue which is different from subdermal fat. Anatomically, buccal fat pad is easy to harvest in the course of dental surgery procedure. In 1802, it was introduced by Bichat, Since Egyedi used buccal fat pad flap for the closure of oro-antral fistula and oro-nasal fistula, it has been widely used as an alternative method for the reconstruction of small to medium-sized intraoral defects in oral and mzxillofacial surgery. Kim et al. reported successful results in the all cases they applied buccal fat pad for the reconstruction of intraoral defect from their 31 months follow-up data. Because intraonal wounds are difficult to complete the layered suture and there are high risks of infection related with wound dental implant surgery, double layer closure using some kind of local flaps or other procedure is recommended. So we are to introduce the useful applications of the pedicled buccal fat pad in the dental surgery procedure from the various case presentations.

In order to evaluate objectively the anxiety level in dental treatment, the author used Biotrainer(BF-120R), one of the skin temperature biofeedback apparatus, to examine 68 dental outpatients on their digital skin temperature change due to routine consecutive dental procedures(oral examination, anesthetic injection, cavity preparation, fissure sealing, polishing). The subjective anxiety level change was also evaluated by visual analog scale. The obtained results were as follows : 1. The skin temperature decreased through consecutive procedures and the temperature in each procedure decreased until 60sec, and then increased on 120sec. 2. The temperature changes in Preparation and Injection were greater than those in other procedures. 3. Generally, male exhibited more change of skin temperature in all procedures than female. 4. Type II, continuously decreasing after procedure, occupied the most in all patients and yhad the lowest beseline temperature. 5. The anxiety level of before-procedure was higher than that of after-procedure and the levels in Injection and Preparation were higher than in other procedures.

In this article, the contemporary root canal treatment procedure using nickel-titanium (NiTi) instruments was reviewed to understand the correlations between the properties of files and safety of the clinical usage. Literatures were reviewed according to the process of clinical procedure of the root canal preparation, mainly for shaping during orifice flaring, glide-path preparation, and main canal instrumentation. Considering the reasons for NiTi file fracture, clinically implacable issues and ideas were discussed to reduce the fracture risk and increase clinical efficiency of the NiTi file systems. Various kinds of NiTi file systems have their own characteristics and properties given from their geometries and heat treatments and so on. Proper selection and careful usage of the NiTi file systems may reduce the risk of file fracture and increase the efficiency of NiTi file systems. Understanding of the clinical implications from the mechanical properties and characteristics of the engine driven NiTi instruments may decrease the risk of NiTi file fractures and increase the success rate in root canal treatment.
