Objectives: The aim of this study was to perform a comparative analysis of the ultrastructural and chemical composition of sialoliths, tonsilloliths, and antroliths and to describe their growth pattern. Materials and Methods: We obtained 19 specimens from 18 patients and classified the specimens into three groups: sialolith (A), tonsillolith (B), and antrolith (C). The peripheral, middle, and core regions of the specimens were examined in detail by histology, micro-computed tomography (micro-CT), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy, and transmission electron microscopy (TEM). Results: In the micro-CT, group A showed alternating radiodense and radiolucent layers, while group B had a homogeneous structure. Group C specimens revealed a compact homogeneous structure. Histopathologically, group A showed a laminated, teardrop-shaped, globular structure. Group B demonstrated degrees of immature calcification of organic and inorganic materials. In group C, the lesion was not encapsulated and showed a homogeneous lamellar bone structure. SEM revealed that group A showed distinct three layers: a peripheral multilayer zone, intermediate compact zone, and the central nidus area; groups B and C did not show these layers. The main elemental components of sialoliths were O, C, Ca, N, Cu, P, Zn, Si, Zr, F, Na, and Mg. In group B, a small amount of Fe was found in the peripheral region. Group C had a shorter component list: Ca, C, O, P, F, N, Si, Na, and Mg. TEM analysis of group A showed globular structures undergoing intra-vesicular calcification. In group B, bacteria were present in the middle layer. In the outer layer of the group C antrolith, an osteoblastic rimming was observed. Conclusion: Sialoliths had distinct three layers: a peripheral multilayer zone, an intermediate compact zone and the central nidus area, while the tonsillolith and antrolith specimens lacked distinct layers and a core.

Objective : Halitosis, or bad breath, is a common concern for many people. The aim of this study was to investigate clinical characteristics of halitosis patients and correlation with their various associated elements. Methods: We surveyed 169 halitosis patients by reviewing questionnaires from the Halitosis Clinic in the Hospital of Oriental Medicine, Kyunghee University from January 2004 to March 2006. The questionnaires contained various items including sex, age, history of smoking and alcohol intake, duration of symptoms in a week, time and condition of severe halitosis, suggestive origin of halitosis, taste abnormality, oral hygiene, self-assessed halitosis severity, dry mouth, postnasal drip, tonsillolith, globus pharyngeus, reflux sensation, too much gas and Winkel tongue coating index. Volatile sulfur compounds were measured with a $Halimeter^{\circledR}$. Results : The halitosis patients actively carried out management methods such as non-smoking, moderation in drink, teeth brushing and tongue scraping in order to decrease their oral malodor. Tongue coating significantly affected the $Halimeter^{\circledR}$ reading score, and tongue coating and dry mouth significantly affected self-assessed halitosis severity. Conclusions: Our results suggest that tongue coating and dry mouth should be treated to improve satisfaction in halitosis patients.

Purpose: Tonsilloliths are calcifications found in the crypts of the palatal tonsils and can be detected on routine panoramic examinations. This study was performed to highlight the benefits of cone-beam computed tomography (CBCT) in the diagnosis of tonsilloliths appearing bilaterally on panoramic radiographs. Materials and Methods: The sample group consisted of 7 patients who had bilateral radiopaque lesions at the area of the ascending ramus on panoramic radiographs. CBCT images for every patient were obtained from both sides of the jaw to determine the exact locations of the lesions and to rule out other calcifications. The calcifications were evaluated on the CBCT images using Ez3D2009 software. Additionally, the obtained images in DICOM format were transferred to ITK SNAP 2.4.0 pc software for semiautomatic segmentation. Segmentation was performed using contrast differences between the soft tissues and calcifications on grayscale images, and the volume in mm3 of the segmented three dimensional models were obtained. Results: CBCT scans revealed that what appeared on panoramic radiographs as bilateral images were in fact unilateral lesions in 2 cases. The total volume of the calcifications ranged from 7.92 to $302.5mm^3$. The patients with bilaterally multiple and large calcifications were found to be symptomatic. Conclusion: The cases provided the evidence that tonsilloliths should be considered in the differential diagnosis of radiopaque masses involving the mandibular ramus, and they highlight the need for a CBCT scan to differentiate pseudo- or ghost images from true bilateral pathologies.

이비인후과 영역에서의 결석증은 타영역에 비해서 비교적 드물게 발견된다. 편도 결석은 만성편도염 환자의 소여포를 채우고 있는 건락성 충진물의 중심부에서 발견된다. 어릴때 편도염을 자주 앓았던 성인에서 발견되는 것이 보통이고, 증상으로는 구개내 이물감 및 악취를 환자 자신이 느낀다. Keratohyalin이 축적되어 결석을 형성하고 있으며 염증이 동반되면 인두통, 인통, 연하통 연하곤란등이 있을 수 있다. 비석은 비강내 이물, 응혈, 세균 가피 농후한 분비물 등이 핵이 되어 그 주위에 칼슘, 마그네슘등이 침착해서 형성된다. 성인에 따라서 외인성과 내인성으로 구분되는데, 외인성의 경우는 비강내 이물에 의해서, 내인성의 경우는 기왕에 존재하던 비질환에 의해서 각각 비폐쇄가 유발되며, 비루에 지장이 초래되어 분비물의 울혈을 가져와서 비석을 형성하는데 기여한다. 성인, 여자에서 잘 생길 수 있으며 대개 편측성이고 비강저부에저 발견되는 것이 보통이다. 대개 완만한 성장을 보이므로 상당기간은 아무런 증상없이 지내다가 비폐쇄, 비출혈, 악취나는 점액농성 분비물을 주소로 내원하는 수가 많다. 저자들은 이비인후과 영역에서도 희귀하게 발견되는 편도결석 1례와 거대한 비석 1례를 최근에 치험하였기에 문헌고찰과 함께 보고하는 바이다.
