Dermoid cyst is a benign neoplasm, so called by teratoma that is derived from both ectoderm and mesoderm during embryonic period. The majority of dermoid cysts are found in the ovaries and approximately only 7% of dermoid cysts are found in the head and neck. The growth of dermoid cysts in the floor of the mouth is considered a rare condition. We report one case of huge dermoid cyst in the floor of mouth suffered with double chin appearance and difficulty in pronunciation and respiration. The cyst was excised successfully only intra-oral incision. Clinical progress was uneventful and postoperative recovery excellent without recurrence.

To investigate the effect of low level laser therapy, the author selected 37 dental students with tender points in both masseters and trapeziuses, also measured maximum comportable opening(MCO), Numerical analog scale(NAS) and pressure pain threshold (PPT). 20 subjects were assigned randomly and were treated with GaAlAs diode laser after ultrasound. The other 17 subjects were treated with ultrasound and laser without irradiation. All the subjects were treated after 2 and 4 day respectively and were examined again after 6 days. And the obtained results were as follows : 1. The MCO of irradiated group increased more significantly after treatment than non-irradiated group. 2. The NAS of irradiated group decreased more significantly after treatment than non-irradiated group. 3. The PPT or irradiated group increased more significantly after treatment than non-irradiated group.

Dermoid cyst of the floor of mouth is infrequent. This cyst has been classified as epidermoid, dermoid and teratoid cyst. Dermoid cyst is more common in young adults and no sex predilection and has generally been present for months to years before progressive enlargement causes interference with the mobility of the tongue and disturbance of articulation and mastication. The authors have recently experienced dermoid cyst of the floor of mouth which was confirmed histopathologically.

Epidermal cyst in the floor of mouth is relatively rare disease. Patients usually present soft and non-tender mass at the midline of mouth floor. Careful history taking and imaging study are needed for the diagnosis and surgical excision is the choice of treatment. We report a case of huge epidermal cyst located in the floor of mouth mimicking plunging ranula, which was successfully removed by transoral surgical excision without any complication. It was diagnosed as an epidermal cyst by pathologic examination.

In order to investigate the biostimulatory effect of low power density laser radiation in vitro, human gingival fibroblasts were cultured in MEM in which experiment groups respectively were made to 30 sec, 60 sec and 90 sec group. The experiments were performed by cell count, DNA and protein content measurements after experimental groups were irradiated with GaAlAs laser every day by forth day and then control group and experimental groups were compared. The results were as follows: 1. Cell counts of experimental groups were increased with exposure time, but showed no significance (P>0.05). 2. When the protein contents were compared, there was a very significant increase in 90 sec. experimental group (P<0.01). 3. When the DNA contents were compared, there was a significant difference only between control and 70 sec. group (P<0.05).

Dermoid cysts located in the floor of the mouth are very rare developmental keratinizing squamous epithelium lined cysts. Anatomically, they are classified as sublingual (median genioglossal), submental (median geniohyoid) and lateral dermoid cysts, and they can be further classified as epidermoid, dermoid, and teratoid cysts by histology. We report a case of sublingual dermoid cyst in a 16-year-old boy presenting as a large sublingual swelling causing speech and swallowing difficulties and discuss the surgical treatment techniques and histopathological features of this lesion.

Korean government enacted the 1st Basic Plan for Low Fertility and Population Ageing in 2005 due to the long-lasting ultra-low birth rate. Based on the Act, Korean government set up a step-by-step strategic goal and establish a basic plan, every five years, to achieve the sustainable development of society corresponding to low fertility and aging society. Over the past decade, the 1st Basic Plan for Low Fertility and Population Ageing (2006-2010) and the 2nd Basic Plan for Low Fertility and Population Ageing (2011-2015) was executed. This year, based on the achievements and limitations of the 1st and 2nd Basic Plan, the 3rd Basic Plan for Low Fertility and Population Ageing begins. In this manuscript, I discuss the background of the 3rd Basic Plan and its significance in oral health area.

상악치조(alveolus), 구개, 편도부의 종양으로 술후 결손을 재건하기에는 여러 피부편이 이용되어 왔지만 그 중에서 최근 풍부한 피하 혈과 공급과 풍부한 조직량으로 하부 비순 피부편을 이용하는 것이 유용하다.

Epidermal cysts in mouth floor are rare. There could be confusions in diagnosis due to location and low incidence. For diagnosis, imaging study and cytology are necessary. The treatment of choice is complete excision intraorally or externally and the recurrence is rare. Some authors prefer sclerotherapy, but the follow up is necessary for malignant change. We report two cases of epidermoid cyst in submental area excised externally with literature review.

Lipoma is one of the most common benign tumors in the human body. However, they are uncommon in the oral cavity. Oral lipomas can occur on the cheeks, tongue, lips, gums and rarely on the floor of the mouth. Clinical symptoms are usually asymptomatic yellow masses. Sometimes the tumor grows and can have difficulty speaking and mastication. The treatment of lipoma is surgical excision, and recurrence is rare. We present a case of oral lipoma in an unusal location on the floor of mouth which is rare in the literature.
