  • When a patient with a fractured anterior tooth visits the clinic, clinician has to restore the tooth esthetically and quickly. For esthetic resin restoration, clinician can use 'Natural Layering technique' and an index for palatal wall may be needed. In this case report, we introduce pre-restoration index technique on a Class IV defect, in which a temporary filling material is used for easy restoration. Chair-side index fabrication for Class IV restoration is convenient and makes a single-visit treatment possible.

  • Non-odontogenic toothaches are frequently present and can be challenge to the dental clinician. A 41-year-old male patient with sharp and spontaneous pain on the right maxillary posterior dentition, which developed as like localized toothache 3 months ago, was finally treated with endoscope assisted sinus surgery on right maxillary sinus. Although the initial clinical characteristics are similar to odontogenic toothache in this patient, previous several treatment with the affected teeth did not alleviate the pain. Sinusitis around the facial structure is one of the common causes to make referred pain to maximally teeth and the sinus toothache resembles the pulpal or the periodontal toothache. The clinician should be well aware of various causes of the non-odontogenic toothache and be able to differentiate them.

  • In recent years, with the introduction of various restorative materials, restorations using CAD/CAM equipment have been increasing in the esthetic dentistry. The critical steps in the fabrication of indirect restorations with CAD/CAM equipment are proper cavity preparation and making accurate impressions. The process of tooth preparation for CAD/CAM restoration should include a mechanical understanding of milling. In addition, during tooth preparation, the clinician should be familiar with additional equipment and techniques for obtaining the convenience. In order to obtain an accurate oral scan, the clinician should understand the limitations of the oral scan and be skilled at techniques for obtaining a successful image when making oral scans. This article focused clinical guidelines for the preparation of CAD/CAM restorations and introduced clinical methods for making successful impression of oral scans in narrow and deep tooth cavity areas.

  • This paper provides practical suggestions for how palliative care clinicians can address the expressions of spiritual struggle voiced by patients and their loved ones. In addition to practical tips for listening and responding, ethical guidance and opportunities for self-reflection related to spiritual care are briefly discussed. Principles to guide practice when the clinician is listening and responding to a patient expressing spiritual struggle include being non-directive, honoring (vs. judging) the patient's spiritual or religious experience, keeping the conversation patient-centered, focusing on the core theme of what the patient is expressing presently, using the patient's terminology and framing, and responding "heart to heart" or "head to head" to align with the patient. Ultimately, the goal of a healing response from a spiritual care generalist is to allow the patient to "hear" or "see" themselves, to gain self-awareness. To converse with patients about spirituality in an ethical manner, the clinician must first assess the patient's spiritual needs and preferences and then honor these.

  • Hoarseness is a postoperative complication of thyroidectomy, mostly due to damage to the recurrent laryngeal nerve (RLN). Hoarseness may also be brought about via vocal cord dysfunction (VCD) due to injury of the vocal cords from manipulations during anesthesia, as well as from psychogenic disorders and respiratory and upper-GI related infections. The clinician or surgeon should 1) document assessment of the patient's voice once a decision has been made to proceed with thyroid surgery ; 2) examine vocal fold mobility, or refer the patient to a clinician who can examine vocal fold mobility 3) examine vocal fold mobility, or refer the patient to a clinician who can examine vocal fold mobility, once a decision has been made to proceed with thyroid surgery 4) educate the patient about the potential impact of thyroid surgery on voice once a decision has been made to proceed with thyroid surgery ; 5) inform the anesthesiologist of the results of abnormal preoperative laryngeal assessment in patients who have had laryngoscopy prior to thyroid surgery ; 6) take steps to preserve the external branch of the surperior laryngeal nerve(s) when performing thyroid surgery ; 7) document whether there has been a change in voice between 2 weeks and 2 months following thyroid surgery ; 8) examine vocal fold mobility or refer the patient for examination of vocal fold mobility in patients with a change in voice following thyroid surgery ; 9) refer a patient to an otolaryngologist when abnormal vocal fold mobility is identified after thyroid surgery ; 10) counsel patients with voice change or abnormal vocal fold mobility after thyroid surgery on options for voice rehabilitation.

  • Recently, the robotic assist system for cardiovascular intervention gets continuously growing interest. The robotic cardiovascular intervention systems are largely two folds, systems for cardiac ablation procedure assist and systems for vascular intervention assist. For the systems, the clinician controls the catheter inserted through blood vessel to the heart via a master console or master manipulator. Most of the current master manipulators have structure of joystick-like pivoting 2 degree of freedom (DOF) handle in the core, which is used in parallel with other sliding switches and input devices. It however is desirable to have customized and optimized design manipulator that can provide clinician with intuitive control of the catheter motion fully utilizing the advantage of the use of robotic structure. A 6 DOF kinematic mechanism that can capture the motion control intention of the clinician in translational 3 DOF and rotational 3 DOF is proposed in this paper. Also, a master-slave motion relationship specially designed for the cardiac catheter manipulation motion is proposed and implemented in an experimental prototype. Design revision for implementation of more efficient motion and experiment in combination with an experimental slave robot system for catheter manipulation are underway.

  • 상악 전치부의 보철 수복은 치과 분야에서 심미성이 크게 요구되는 치료이다. 상악 전치부의 보철 수복을 통하여 치아의 외형, 배열, 색조 등을 개선하면 심미성을 향상시키는 것이 가능하다. 특히 전치부 심미 수복을 위해서는 진단과정에서 환자의 안모 및 치아와 입술과의 관계, 치아와 치은 관계 등을 평가하고, 환자가 요구하는 바를 정확히 파악할 필요가 있다. 환자와 술자 및 기공사 간의 원활한 의사소통을 통하여 환자의 요구사항을 충실히 반영하기 위한 도구로서 DSD (digital smile design) 개념을 적용할 수 있다. 이 증례에서는 상악 중절치의 선천적 결손으로 인하여 대칭성을 구현하기 불가능한 상황에서 DSD를 활용하여, 환자 안모와 상악 전치부의 전체적인 조화를 추구하는 것을 목표로 하였으며, 이를 통해 환자와 술자 모두 만족할 만한 심미적인 결과를 얻었기에 이를 보고하고자 한다.

  • 목적: 총의치를 사용하고 있는 무치악 환자에서 의치 사용에 대한 환자의 평가와 술자간의 평가를 비교하고자 하였다. 대상 및 방법: 의치를 사용한지 최소 1년 이상 경과된 총의치 장착자 중 43명의 환자가 정기검진에 응하였다. 환자에 관한 여러 정보를 얻기 위해 다양한 문헌에서 얻은 자료를 토대로 설문지를 개발하고 술자의 객관적인 평가간 일치도를 분석하였다. 술자의 평가 사항으로는 유지, 안정, 교합과 같은 기능적 항목과 의치의 상태를 포함한다. Friedman test와 Cohen's Kappa값을 이용하여 통계학적인 분석을 시행하였다. 결과: 의치 장착자의 평가와 술자의 평가 간에는 약하거나 약간의 차이가 있다. 상악 의치보다는 하악의치에서 차이가 더 크게 나타났으며 심미와 저작은 중등도의 차이가 있었다. 결론: 의치에 대한 환자의 주관적, 술자의 객관적인 평가는 일치하지 않으나 큰 차이를 보이지 않는다.

  • 매복치의 치료는 그 발생원인, 치아의 발육단계, 매복된 위치 및 맹출 경로, 환자의 협조도 등을 고려하여 치료방법을 결정한다. 일반적으로 맹출에 영향을 줄 수 있는 유전적, 전신적 유발인자가 있다면 이의 치료와 더불어 맹출 유도를 위한 조기치료의 필요성이 있으며, 맹출에 장애를 주는 물리적 요소가 존재한다면 이를 우선적으로 제거해야 한다. 그러나 맹출과 관련된 어떠한 요인이나 맹출공간 부족 등이 발견되지 않았다면 유치 발거 이외에 치아를 외과적으로 노출시킨 후 교정장치를 부착하고 교정력을 이용하는 치아맹출 유도법, 그리고 매복치를 외과적 재위치 또는 이식하는 방법을 사용할 수 있다. 자가치아이식술을 시행할 경우 치아발육 상태를 고려한 적절한 시기의 선택, 적절한 치조와 형성 및 이식치아의 발거와 식립에 있어 외상의 최소화 등이 성공에 중요한 요소다. 본 증례에서는 상악우측중절치의 미맹출을 주소로 내원한 7세 여자 환자에서 CT검사결과 상악우측중절치의 치관부가 전비극에 근접하여 협측으로 위치되어 있으며 치관부에서 만곡이 관찰되었다. 치근은 Nolla's stage 7정도의 발육을 보였으며 이에 자가치아이식을 시행하였다. 주기적인 관찰결과 치근흡수 등의 합병증 없이 양호한 치유양상이 관찰되었다.

  • B cells, by virtue of their diverse roles in immune responses to foreign and self antigens, have become of increasing interest to the clinician as well as the basic immunologist. In particular, it is now apparent that the development of B cell unresponsiveness in antibody and T cell mediated autoimmune disorders and the transplant setting is both worthwhile and achievable.
