The soft acrylic stent is easily inserted and well adapted to the palatal soft tissue ever the surgical site in the removal of torus for supporting the flaps into proper and designed position to promote good healing. The stent is sutured to the mucobuccal fold in both upper premolar areas. To achieve the satisfied and good result, the model of the patient's upper arch should be well prepared in advance.

In Thailand nowadays AIDS is not completely under control. This is evident from reports which show an increasing number of HIV-positive patients. Since an unknown number of HIV-infected persons who are either undiagnosed or asymptomatic come to get dental service, fears of getting infected with HIV have been developed among dental professionals. This article summarizes a number of past studies and reports on HIV transmission in dental work and discusses the possibility of AIDS infection and dental occupational risk. It also urges dental professionals to take effective safety precaution against the infection. This is for their own and their patients' well-being and hopefully for Thailand's success in controlling AIDS.

Malignant fibrous histiocytoma is a neoplasm that can occur both in soft tissue and bone but it is preponderantly found in soft tissue of the extremities. The majority of cases occur in late adult life; and, males are affected more often than females. Most of the patients come to see the doctors because of a mass in various regions and pain. The prognosis is poor, patients usually die from metastasis of the neoplasm to important organ. According to some reports, the neoplasm can occur in oral soft tissue and jaw, thus, dentists should know about important features of the neoplasm in order to be able to diagnose it from other benign oral lesions and can treat correctly.

Oral candidiasis is the symptomatic development of superficial infection with many forms of clinical manifestation. The treatment of choice should include the antifungal agents which act topically in the oral cavity so that the systematic adverse effects are minimal. They should have good impregnation to the oral mucosa and prolonged effect. In patients with chronic or recurrent infection or being immunological compromised, successful treatment can be achieved by increased dosage and extended duration of antifungal therapy.

Spacing due to periodontal disease with migration of adjacent teeth to extraction space is a common problem in adult patients. Appropriate orthodontic treatment is one of the measures to prevent aggravation of periodontal structure. The objective of the article was to present basic principles of adult orthodontics comprising: establishment of mandibular position, control of tooth movement in three dimensions of space, anchorage preparation, prevention of iatrogenic effects and prevention of relapse along with 2 case reports.

A case report of upper edentulous arch patient had been to remove torus palatinus. The post-operative wound was protected by the splint. It was made from thin clear plastic and was pressed under high pressure vacuum on the study model. The study model was made by taking impression with easily and conveniently technique. The study model is also representative the post-operative condition of upper edentulous arch. After the palatal torectomy the splint was inserted and immobilized by suturing with black silk #3/0.

Unerupted teeth have been a familiar problem in dental profession for many years. This article described how to manage the unerupted teeth including 2 case reports. The treatment planning can be either no treatment, orthodontic treatment or surgical treatment alone, or combined orthodontic and surgical treatment. With comprehensive analysis, consideration of etiologic factors, diagnosis and proper treatment planning, unerupted teeth can be brought into the dental arch for normal functional and esthetic stability.

This article reports a case of gingival hyperplasia induced by nifedipine. It is a relatively new drug used in the treatment of hypertension, ventricular arrhythmias and angina. Both clinical and histological conditions and also treatment resemble other drug-induced gingival hyperplasia.

The ultimate goal of periodontal therapy includes not only the arrest of progressive periodontal disease, but also the restitution of those parts of the supporting apparatus which were destroyed by the disease. Regeneration of periodontal structures dissolved because of periodontal disease is the goal of reconstructive periodontal treatment procedures. The achievement of this goal requires the formation of new cementum with inserting collagen fibers of previously periodontitis involved root surfaces possibly with a concomitant regeneration of supporting alveolar bone. Healing, after periodontal therapy, leads to the formation of long junctional epithelium, root resorption, ankylosis, etc. These are repair process and not one of regeneration. But guided tissue regeneration seems to lead to regeneration with active periodontal ligament cells.
