Objectives: The aim of this study was to compare morbidities and duration of surgery, as well as bone formation in alveolar defects reconstructed with symphysis bone combined with allograft and iliac crest bone graft in patients with cleft palate. Patients and Methods: This randomized clinical trial was performed with 22 patients with unilateral alveolar cleft with a follow-up period of 12 months. In 12 patients, alveolar defects were reconstructed with chin bone graft plus allograft (Group A), while for the other 10 patients, iliac bone crest was used as donor site (Group B). Duration of surgery as well as occurrence of morbidities and complications were recorded. In addition, cone-beam computed tomographic (CBCT) scans were performed before surgery and 12 months after surgical procedures in order to compare bone formation between the two groups. Results: Postoperative CBCT demonstrated a mean bone fill percentage of 76.9% of the alveolar defect in Group A, compared with 77.0% in Group B. Paresthesia in the lower lip or chin did not occur in any patients of Group A. The mean duration of the surgical process was significantly shorter for Group A (40 minutes vs 76 minutes, P<0.001). In addition, patients in Group A regained normal gait faster than patients in Group B (1 day vs 9.5 days). Conclusion: Mandibular symphysis bone graft in combination with allograft results in favorable outcomes in patients with unilateral alveolar clefts.

It has been known that the color of skin reflects the blood flow within. In lips, the capillaries close to the skin surface are numerous; hence lips are redder than the rest of face. However, dermatological research on lips is not as advanced as research on facial or body skin, and little was known about the relationship between relatively dull-colored lips and skin blood flow. The physiological differences between colorful and dull-colored lips were studied by a two-dimensional laser Doppler blood flow analyzer, a spectrometer for the measurement of the degree of oxygen saturation, and a confocal microscope for observing inside lips non-invasively. Dull-colored lips and the corner of lips (dull-colored compared to the center) showed relatively poor blood flow and lower oxygenated hemoglobin. It was found that colorful lips (generally the young) had a blood flow that tended to run straight in parallel with the skin surface. This unique blood-capillary structure can express clear red blood. Those with dull-colored lips had lost this unique structure. Their blood ran perpendicularly from the deep of the skin and down back again into the deep part as like the blood circulation patterns of facial skin. Therefore, the lips of the latter group had fewer blood capillaries near skin surface in the lips than that of the colorful-lips group. A lipstick containing a-glucosyl-hesperidin, which is derived from certain citrus fruits and can enhance blood circulation, was applied for evaluating its effects. Blood flow was increased 30 min after the application. After two weeks of daily application, the lips' condition became noticeably less dull. These findings suggest that the decrease of blood flow in dull-colored lips is caused by the loss of the unique capillary structure and the use of the lipstick to increase blood flow can give a vivid color to lips.

A 49 years old male patient was referred from the Department of Medicine, KNUH for the management of painful oral lesions. The patient had disability of food and drug intake due to multiple intraoral ulcers. Extraoral findings showed upper and lower lip swelling, crust formation on the lips. The lesions were diagnosed as Stevens-Johnson syndrome based on clinical and hematologic findings. The patient was treated with saline irrigation and pulsed Nd:YAG laser irradiation. After 5 daily treatment, the lesions decreased in size and severity, and the patient became more comfortable for food intake and speeching. It was suggested from the results of this clinical trial that a pulsed Nd:YAG laser therapy would be helpful for the symptoms associated with Stevens-Johnson syndrome.

Objectives: This randomized clinical trial aimed to assess the effectiveness of buccal infiltration with piroxicam on the anesthetic efficacy of inferior alveolar nerve block (IANB) with buccal infiltration in irreversible pulpitis, with pain assessed using the Heft-Parker visual analogue scale (HP-VAS). Materials and Methods: This study included 56 patients with irreversible pulpitis in mandibular molars, randomly distributed between 2 groups (n = 28). After evaluating the initial pain score with the HP-VAS, each patient received IANB followed by buccal infiltration of 2% lignocaine with adrenaline (1:80,000). Five minutes later, the patients in groups 1 and 2 were given buccal infiltration with 40 mg/2 mL of piroxicam or normal saline, respectively. An access opening procedure (AOP) was performed 15 minutes post-IANB once the individual showed signs of lip numbness as well as 2 negative responses to electric pulp testing. The HP-VAS was used to grade the patient's pain during caries removal (CR), AOP, and working length measurement (WLM). Successful anesthesia was identified either by the absence of pain or slight pain through CR, AOP, and WLM, with no requirement of a further anesthetic dose. A statistical analysis was done using the Shapiro-Wilk and Mann-Whitney U tests. Results: The piroxicam group presented a significantly lower (p < 0.05) mean pain score than the saline group during AOP. Conclusions: Buccal infiltration with piroxicam enhanced the efficacy of anesthesia with IANB and buccal infiltration with lignocaine in patients with irreversible pulpitis.

This case report presents inferior alveolar nerve (IAN) repositioning as a viable approach for implant placement in the mandibular molar region, where challenges of severe alveolar bone width and height deficiencies can exist. Two patients requiring implant placement in the right mandibular molar region underwent nerve transposition and lateralization. In both cases, inadequate alveolar bone height above the IAN precluded the use of short implants. The first patient exhibited an overall low alveolar ridge from the anterior to posterior regions, with a complex relationship with adjacent implant bone level and the mental nerve, complicating vertical augmentation. In the second case, although vertical bone resorption was not severe, the high positioning of the IAN within the alveolar bone due to orthognathic surgery raised concerns regarding adequate height of the implant prosthesis. Therefore, instead of onlay bone grafting, nerve transposition and lateralization were employed for implant placement. In both cases, the follow-up results demonstrated successful osseointegration of all implants and complete recovery of postoperative numbness in the lower lip and mentum area. IAN repositioning is a valuable surgical technique that allows implant placement in severely compromised posterior mandibular regions, promoting patient comfort and successful implant placement without permanent IAN damage.

The mentalis muscle is a paired muscle originating from the alveolar bone of the mandible. This muscle is the main target muscle for botulinum neurotoxin (BoNT) injection therapy, which aims to treat cobblestone chin caused by mentalis hyperactivity. However, a lack of knowledge on the anatomy of the mentalis muscle and the properties of BoNT can lead to side effects, such as mouth closure insufficiency and smile asymmetry due to ptosis of the lower lip after BoNT injection procedures. Therefore, we have reviewed the anatomical properties associated with BoNT injection into the mentalis muscle. An up-to-date understanding of the localization of the BoNT injection point according to mandibular anatomy leads to better injection localization into the mentalis muscle. Optimal injection sites have been provided for the mentalis muscle and a proper injection technique has been described. We have suggested optimal injection sites based on the external anatomical landmarks of the mandible. The aim of these guidelines is to maximize the effects of BoNT therapy by minimizing the deleterious effects, which can be very useful in clinical settings.

성장기 골격성 제III급 부정교합의 원인은 상악 열성장, 하악 과성장과 두 양상의 조합형태로 나뉠 수 있다. 이중 상악 열성장을 동반한 성장기 골격성 제III급 부정교합의 경우, 상악골 전방견인 장치의 사용이 추천되고 있는데, 이러한 장치의 치료효과는 상악골의 전하방 이동과 하악골의 후하방 회전으로 알려져 있다. 국내외 선학들에 의해 상악골 전방견인 장치의 치료효과에 대한 많은 동물실험과 임상실험 결과가 발표되었으나, 연조직 측모 변화에 대한 연구는 미비한 상태이고, 또한 치료를 받은 환자간의 치료효과에 대한 비교도 부족한 상태이다. 이에 저자는 상악골 열성장으로 인한 성장기 골격성 제III급 부정교합으로 진단받고, 상악골 전방견인 장치로 치료 받은 93명의 환자를 성별, 치료개시 나이별, 구개봉합 opening여부(구강내 장치), 안모성장 형태에 따라 분류하여, 각 유형에 따라 어떠한 경조직과 연조직 측모의 변화가 관찰되는지 여부와, Angle씨 제 I 급 부정교합의 정상군 20명과 상악골 전방견인 장치로 치료받은 환자 사이에 경조직과 연조직에 있어서 성장량과 치료량에 어떠한 관계가 있는지 비교하여 다음의 결론을 얻었다. 1. 상악골 전방견인 장치 사용시 골격적 계측항목과 치아와 연조직 계측항목에서 성장량보다 많은 치료에 의한 변화량을 관찰할 수 있었다. 2. 남녀별 치료개시 나이에 따른 상악골 전방이동량과 하악골의 후하방 회전량에는 유의차가 없었다. 3. R.P.E.에서 La-Li보다 유의성 있는 상악골(A point)의 전방이동을 보였으며, 상악 전치의 순측 돌출이 La-Li를 사용하였을때 보다 감소되었다. 4. 안모성장 형태에 따라서는 상악골 전방이동량에는 유의차가 없었으나, 하악골의 후하방 회전을 나타내는 계측치에서 counterclockwise군이 clockwise군보다 많은 변화를 나타냈다. 5. 상순과 하순의 후경변화는 하부 골조직과 상하악 치아의 위치변화와 높은 상관관계를 보였으며, 상순의 고경과 nasolabial angle이 증가하고, mentolabial angle이 감소되었다.

동양권 특히 한국인에게서 자주 발견되는 제III급 부정교합은 하악과성장, 상악열성장 또는 혼합형으로 나눌 수 있다. 그 중 골격성 제III급 부정교합은 대부분이 상악골의 열성장을 동반하고 있으며, face mask는 상악골 열성장을 나타내는 성장기 아동에서 주로 쓰이는 악정형 장치이다. face mask는 전치부 반대교합과 상악골의 위치를 개선하여 대부분 적절한 교합관계를 이루어 양호한 안모를 얻을 수 있으나 어떤 경우는 상하순이 전방으로 돌출된 듯한 바람직하지 않은 안모를 얻는 경우도 있다. 따라서 치료 전 어떠한 환자의 조건이 치료 후 바람직한 교합관계와 안모를 얻을 수 있는지를 술자가 알 수 있다면 face mask 치료의 결과 예측과 한계에 대하여 보다 잘 판별할 수 있을 것이다. 본 연구는 성장기 제 III 급 부정교합 아동의 치료 후 양호한 안모를 얻는데 도움을 주고자 시행하였으며 상악골 전방견인 치료후 양호한 안모를 보이는 군(Group 1, n=12)과 양호하지 못한 안모를 보이는 군(Group 2, n=14)으로 나누고, 치료 전과 치료 후의 측방 두경부 방사선 계측 항목을 이용한 후향적인 연구로 통계처리를 시행한 결과 다음과 같은 결론을 얻었다. 1. 골격성 부조화로 인해 상악전치가 이미 순측경사되어 전돌되어있을 수록 치료 후 안모는 좋지 않았으며, 상악전치와 관련된 전방 치조골(prosthion)의 전돌 또한 안모에 영향을 주었다. 2. 치료 전 상악골과 하악골이 이루는 각도가 작을수록(NL-ML) 좋은 안모를 나타내었다. 3. 치료 전 하순의 돌출도가 클수록 치료 후 bialveolar protrusion되는 경향을 나타내었다. 4. 치료 후 하악골의 후하방회전정도가 클 수록 좋지 못한 안모를 보였다.

Purpose: The result of all malignant neoplasms including oral cancer is decided by long-term prognosis. However, until now, there are only a few reports about long-term prognosis of cancer secluded in the oral cavity. So, we investigated all patients that visited our clinic for oral squamous cell carcinoma (SCCa) for the last 10 years. From this survey, we hope to find important factors that influence prognosis of the disease. Patients and Methods: A retrospective study was performed for patients that visited the oral oncology clinic for oral cancers from Jan. 2001 to Feb. 2010. We selected the patients that were diagnosed with SCCa and received curative treatment. In these patients, we investigated basic epidemiology, smoking history, body mass index, recurrence rate, treatment methods, pathologic data and 5-yr survival rate. Results: There was a total of 185 patients (115 males, 70 females and mean age: 57.3 years) that visited the oral oncology clinic for oral SCCa. Areas of primary lesion were tongue (105 cases, 57%), lower gum (19 cases, 10%), floor of mouth (16 caess, 8%), retromolar trigone (12 cases, 6.5%), and buccal cheek (11 cases, 6%). Other involved areas were upper gum, palate, lip, and salivary glands-of 1 case each. The overall 5-year survival rate was 63.7%. The factors that influenced prognosis of the disease were stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. Conclusion: The factors that influence prognosis of disease are stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. To point out a current trend, the mean age of patients that developed oral cancer was lower than that of before. Secondly, the prevalence of oral cancer in non-smoker are on the rise. Thus, further studies on etiology and epidemiology should be done.
