Ectodermal dysplasia is a genetic disorder in which various clinical manifestations involve two or more of the differentiated tissues of the ectoderm. Facial deformity, which is frequently associated with ectodermal dysplasia, appears in the form of cleft lip or cleft palate, especially in the middle facial area.Cleft and tooth defects result in decreased alveolar bone development.This leads to severe skeletal incongruity. Facial features include frontal protrusion, malar bone hypoplasia, flat nose, mandibular prominence and long lower facial height. This clinical report presents treatment including orthognathic surgery of a patient with Hypohidrotic Ectodermal dysplasia with cleft palate.

Dentinogenesis Imperfecta, with a high incidence rate of 1 : 6 - 8000, is inherited by autosomal dominant genetic transmission. This dental disorder causes discoloration of the teeth and the enamel and dentin show hypoplastic or hypocalcified defects which lead to frequent fractures and rapid attrition. Therefore, timely treatment is necessary for the preservation of the remaining teeth. In this particular case, a 19-year-old patient suffering from Type 1 dentinogenesis imperfecta showed signs of brownish hued teeth with multiple fractures, a loss of vertical dimension, excessive interdental space in the maxillary anterior teeth, and a lack of 5 posterior teeth. To improve the esthetic appearance of the anterior teeth, the vertical dimension was increased. Resin caps were used to alleviate the difficulty of taking an impression of multiple teeth at once. Monolithic zirconia materials used in this case showed high fracture strength and the ability to mask the discoloration of the teeth and therefore, functionally and esthetically favorable results were achieved.

Generally, X-ray examinations for dentistry use low energy radiation. It explains that the radiations are mainly absorbed to a human body because of the weak permeability. We made up some counterplans for decrease in radiation exposure, when guardians and radiologists are overexposed owing to unavoidable circumstances. The equipments for the test are GX-770 and CRANEX TOME CEPH which are used for various exams. Besides we measured the radiations in the projection room and in the control room using model 2026c and 20X6-1800. According to the test, the measurement value in the control room was low dose below $20{\mu}R$, the maximum dose in the projection room was $702.8{\mu}R$ and the measurement value of back dose was higher than lateral one. As the result, if we use a shielding door, it's effective for radioprotection and when we didn't prepare protectors, we should secure appropriate distance and be situated at the side area($90{\sim}135^{\circ}$) on the basis of centeral radiation. That way will provide valuable aid for radioprotection.

Mucoceles and Ranulas are mucous retention phenomena, ie, they develop from the extravasation or retention of mucous after trauma to the sublingual gland or one of the minor salivary glands. Mucoceles are chronic in nature, and local surgical excision is necessary. To minimize the chance for recurrence, the underlying feeder glands should be removed in continuity with the mucocele. Ranula is a term used for mucoceles that occur in the floor of the mouth Treatment consists of marsupialization and/or removal of the feeding sublingual gland. Marsupialization entails removal of the roof of the intraoral lesion. However this procedure is often unsuccessful. Some prefer initially to excise the entire sublingual gland. This case report presents two cases. one case was developed on lower lip and treated by marsupialization. There was no recurrence during follow up period.

The malignant tumor in childhood is one of the main causes of children s death due to disease. The traditional treatment for the malignancy is known for the radiation therapy and the chemical therapy or both. However, the treatments tend to induce intraoral complications. Different from adults, almost all children on cancer therapy are expected to have dental complications, because their permanent teeth are on the developmental stage. The degree of dental complication depends on the patient's age, type of chemical and other factors-radiation dose and frequency. In this report, 3 children who had experienced the anti-cancer therapy on their age between 1 and 4 years were selected and dental complications were examined. The children have chance for the various oral complications including the developmental problems such as agenesis, microdontia and hypoplasia of the teeth. Therefore, it's important to understand the side-effects of anticancer therapy during the permanent teeth had been developmental stage in young patients. Also, oral health care specialists, including pediatric and hospital dentist can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment undergoing anticancer treatment.

Malignant tumours of the oral cavity that require resection of the tongue result in severe deficiencies in speech and deglutition. In such patients, improvements in mastication, swallowing, and speech may be reasonable goals for treatment. The viability of a prosthodontic approach to treatment depends on the type and extent of surgery. In a total glossectomy, a mandibular tongue prosthesis is the treatment of choice. Mandibular tongue prosthesis occupies the space in the floor of the oral cavity. It provides the patients with a platform for directing food into the esophagus and aids in speaking. This type of prosthesis can achieve that protection of the underlying fragile tissue and improvement in appearance and psychosocial adjustment. This case report describes the technical steps involved in prosthetic rehabilitation for a glossectomy patient.

Treacher Collins syndrome is inherited as an autosomal dominant trait with variable penetrance. It shows a marked variability even in the same family. This syndrome is developmental defect affecting the branchial arches. It is not usually associated with acute respiratory distress, but has symptoms of microtia, hypoplastic zygomatic bones, hypoplastic mandibular rami, and bilateral coloboma. It usually requires an emergency operation immediately after the birth. We experienced an infant with Treacher Collins syndrome who showed retrognathia, glossoptosis, microtia, and cleft palate. Intermittent cyanosis, depression of the chest, respiratory difficulty associated with airway obstruction, and swallowing difficulty were also observed. To relieve severe upper airway obstruction caused by retrognathia and glossoptosis, we simultaneously performed tongue-lip adhesion and subperiosteal release of the floor of the mouth. The respiratory and swallowing difficulties were relieved and the tongue repositioned anteriorly. We report the present case with a review of the literature.

Lipoma is most common tumor that compromises 4% to 5% of all benign neoplasm, but in oral cavity it is uncommon. In oral cavity, lipoma presents painless, asymptomatic, slow growing, but sometimes it grows to larger size causing deformities, mastication and speech difficulties. While lipoma in commonly affects female patients (68-73%), oral lipoma appears more frequently in male patients. The majority of oral lipoma is seen after the age of forty (uncommon in children). Lipoma of oral cavity and maxillofacial region occurs most commonly in the parotid region, followed by the buccal mucosa, lip, tongue, palate, mouth floor, gingiva in order. A treatment of lesion is surgical excision with recurrence not expected. In this paper we present the case of a patient who has Lipoma in the mouth floor.
