Subcutaneous emphysema is relatively rare postoperative complication in the oral and maxillofacial region. Most cases reported in maxillofacial area relate to the use of high-speed handpiece. However, in this case, subcutaneous emphysema was caused by compressed air blow performed during suture removal . Cone-Beam Computed Tomography was conducted to evaluate the extent of diffusion bubbles.. In this report, we describe etiology, diagnosis, prevention and management of subcutaneous emphysema in the maxillofacial area.
Silver diamine fluoride (SDF) is an alkaline topical solution and it derives from the conjunction of silver nitrate and fluoride. It reduces the growth of cariogenic bacteria, inhibits degradation of dentinal collagen, impedes demineralization and enhances remineralization. It is inexpensive due to the low cost of materials and its application to dental surface is very simple and requires relatively short chair time. Previous studies have shown that the dental caries prevention effect of SDF is superior or similar to topical fluoride application. The main disadvantage of SDF is its esthetic result, and it permanently blacken carious enamel and dentin. The use of SDF has not yet been approved in Korea, but it may be helpful to prevent and treat dental caries in patients with special health care needs and uncooperative young patients.
Dental caries and periodontitis are the major concerns of oral disease to human, and its etiologic factor is dental biofilm. The aim of this study is to discuss the clinical application method and the meaning of dental biofilm control in the disabled patients. Generally, ultrasonic scaler are likely to generate excessive stimulus to the disabled patients. Rubber cup application using Ni-Ti engine could remove dental biofilm more comfortably to the disabled patients.
Patients with a wide range of cerebrovascular disease may have difficulty in opening their mouths, resulting in failing to swallow foods and maintain their oral hygiene. K-point was introduced as an effective trigger point to stimulate the jaw opening reflex for those patients. K-point stimulation may be useful as one of methods of helping open the jaw for dental examinations, or for placing foods onto the dorsum of the tongue and swallowing them effectively. Although this method cannot always guarantee the success of the jaw opening for every patient, it may still be considered to be an effective one to apply to patients having difficulty in jaw opening and swallowing disorder.
