One of the most common procedures in dentistry is the inferior alveolar nerve block anesthesia but visual problem can occur during this procedure. Transient visual acuity decrease after inferior alveolar nerve block anesthesia can result from unintended intravascular injection. In this case report, we present ocular complication that has rarely been reported. The understanding of anatomy related to this case is discussed with suggestions for proper management of the patients. The dental management for ocular complications includes a correct diagnosis, management by understanding of patient's anatomic variations. This will prevent intravascular injection.

Usage of the rubber dam has been advocated by countless number of dentists. The advantages of the rubber dam such as the following are well-known 1. Moisture control. 2. Improved field of vision. 3. Ease of approach. 4. Soft tissue retraction and Injury prevention. 5. Prevention of aspiration of materials or instruments. 6. Shortened chair time. 7. Induction of nasal breathing during administration of $N_2O-O_2$ sedation. Recent reports indicate the rubber dam can protect the dental staffs from the infection when treating HBV or HIV positive patients. Also, improved moisture control and freeing of both hands allowed by the rubber dam makes it very useful when bonding orthodontic brackets. This case study presents the various clinical application of the rubber dam on patients visiting SNUDH dept. of pediatric dentistry to emphasize the importance of its use in pediatric dentistry.

Purpose : Dental trauma is frequently unpredictable. The initial assessment and urgent treatment are essential for dentists to save the patient's teeth. Mobile-phone-assisted teleconsultation and telediagnosis for dental trauma could be an aid when a dentist is not available. In the present in-vitro study, we evaluated the success rate and time to transfer images under various conditions. Materials and Methods : We analyzed the image quality of cameras built into mobile phones based on their resolution, autofocus, white-balance, and anti-movement functions. Results : The image quality of most built-in cameras was acceptable to perform the initial assessment, with the autofocus function being essential to obtain high-quality images. The transmission failure rate increased markedly when the image size exceeded 500 kB and the additional text messaging did not improve the success rate or the transmission time. Conclusion : Our optimal protocol could be useful for emergency programs running on the mobile phones.

Objectives: Fast-setting pozzolan cement (Endocem, Maruchi) was recently developed. The aim of this study was to investigate the effects of various root canal irrigants on the washout of Endocem in comparison to the previously marketed mineral trioxide aggregate (ProRoot; Dentsply) in a furcal perforation model. Materials and Methods: ProRoot and Endocem were placed into acrylic molds on moist Oasis. Each mold was then immediately exposed to either physiologic saline, 2.5% sodium hypochlorite (NaOCl), or 2% chlorhexidine (CHX) under gentle shaking for five minutes. Washout testing was performed by scoring scanning electron microscope (SEM) images. Results: Endocem exhibited higher washout resistance compared to ProRoot, especially in the NaOCl group. Conclusions: These results suggest that Endocem can be considered a useful repair material for furcal perforation, especially in a single-visit scenario.

While it is reasonably well known that certain dental procedures increase the temperature of the tooth's surface, of greater interest is their potential damaging effect on the pulp and tooth-supporting tissues. Previous studies have investigated the responses of the pulp, periodontal ligament, and alveolar bone to thermal irritation and the temperature at which thermal damage is initiated. There are also many in vitro studies that have measured the temperature increase of the pulp and tooth-supporting tissues during restorative and endodontic procedures. This review article provides an overview of studies measuring temperature increases in tooth structures during several restorative and endodontic procedures, and proposes clinical guidelines for reducing potential thermal hazards to the pulp and supporting tissues.

Adrenoleukodystrophy (ALD) is a rare, inherited disorder that leads to progressive brain damage and failure of the adrenal glands. It is passed down from parents to their children as an X-linked genetic trait. Therefore, it affects primarily males especially under the age of 10. People with ALD have excessive accumulation of very long chain fatty acids (VLCFAs) in their brain because they do not have the enzyme which break down these fatty acids. Special method for treatment of ALD is not available. Eating a diet low in VLCFAs and taking special oils, called Lorenzo's oil, can lower the blood levels of VLCFAs. But this oil cannot stop the destruction of nerve cell. This article presents a case report: Dental treatment of a 11-year-old male patient with ALD under general anesthesia. Careful management must be required during treatment procedure because of difficulty in cooperation, seizure disorders, gastroesophageal reflux, pulmonary aspiration and airway complications.
