Burning mouth syndrome is an intraoral pain disorder, stinging and/or itching sensation of the tongue or oral mucous membranes. Numerous causes have been suggested, including local factors such as candidiasis and denture trauma, systemic factor such as nutritional deficiencies, diabetes and climacteric, xerostomia, miscellaneous conditions such as psychogenic factors. A systematic approach for the success in diagnosis and treatment is included history taking, complete mouth examination and laboratory investigation.

A six-month, double blind, cross over clinical study was conducted to compare the effect of a commercially available anticalculus dentifrice and a placebo dentifrice on supragingival calculus deposits. Fifty adult subjects who entered the study were given an oral prophylaxis and were assigned to use either pyrophosphate/copolymer toothpaste or a placebo toothpaste for a period of three months. They were then scored for calculus deposits using the Volpe-Manhold method, received a second oral prophylaxis and used the alternate dentifrice for a second three month period of time. The subjects were again scored for calculus deposits and the study was completed. The results indicated that pyrophosphate/copolymer toothpaste reduced supragingival calculus formation by 37.07%, as compared to the placebo dentifrice. This reduction was significant at the 99% level of confidence.

The cytomorphological effects of folic acid were studied using in vitro established human oral epithelium. It was demonstrated that a concentration twice that used clinically (200 micrograms/ml) did not induce marked cytotoxic reaction in the cultured cells. The most pronounced changes were observed in cultures exposed to 200 micrograms/ml folic acid both in primary culture and subculture. The cultures displayed areas of degenerating cells showing oedema and increased translucency of the cytoplasm, flattened cells with distinct tonofilaments and atypical mitotic figures. Identical changes were found in cultures exposed to 50 and 100 micrograms/ml folic acid but to a lesser extent than in 200 micrograms/ml. These changes indicated that folic acid increased the number of cells undergoing terminal differentiation. From this study we suggested that folic acid when applied topically may play a role in local stimulation of epithelial cell differentiation leading to enhanced healing of oral ulcers.

A case of prolonged socket bleeding after extraction is reported to have been caused by a recent green pit viper snake bite. The snake is a common tropical creature. Several cases bitten are seen in general medical clinic yearly. Pain and local symptoms lead most patient to doctor's attention; while coagulopathy, the other clinical features are usually not being aware of. The 66-year-old patient who had been bitten by the snake a day earlier, of having tooth extraction was referred to Rachaburi Hospital Dental clinic of having post-extraction delayed haemostasis. A routine heamostasis as of gel foam with adrenalin pack and vitamin K injection was unsuccessful. Further laboratory investigations confirmed that he had hypofibrinogenemia as the pathogenic cause. Fresh frozen plasma was administered, haemostatis was satisfactory within 24 hrs.

This article described the over-view of pre-surgical treatment for cleft lip and palate infant in order to provide some ideas for general dental practitioners so that they can help such patients as much as possible.

A case report of endodontic surgery of maxillary left lateral incisor with external root resorption which perforated the root canal was presented. The cause of this abnormality was due to chronic inflammation. The patient had the history of pain and swelling. After root canal filling by thermoplasticized warm gutta-percha technique, the resorption defect and the apical apex were filled with amalgam via a surgical approach. The patient remained asymptomatic 8 months later, radiographic appearance revealed a sign of bone repair.

Metronidazole is effective against certain anaerobic infections such as Bacteroides gingivalis and Spirochetes with clinical signs of rapidly progressive periodontitis and refractory adult periodontitis. The use of Metronidazole in adjuvant with scaling, root planing, and personal oral hygiene instruction caused a significant improvement of the periodontium.

The survey of the dental treatment needed for the slum people in Bangkok was part of the mobile public health service program under the Bangkok Community Development Project, Ministry of University Affairs which was proposed by the Bangkok Representatives, Prachakorn Thai Party which aimed to provide the needed dental service to the slum people. There was a limited amount of time to carry out the survey, because the main purpose of the project was to provide the services, the survey data was obtained without any affect to the service time. From 156 slums and 40 primary schools in Bangkok 19,333 cases received the services. It was found that 15,681 cases needed scaling, 42,183 teeth needed filling and 36,923 teeth needed extractions. The Prevalence of tooth decay was 4.1 teeth per person. The clinician could carry out this survey without the need for high technical skill in Dental public health. This kind of data was enough for planning the dental service program. By doing this kind of work, we would have more information for improving our dental profession. The good and up to date data would bring us the unity in our dental profession.

The purpose of this research was to explore the oral health of the Public Health Midwifery and Nursing students of 1987-1988. Fiscal year Budget, totally 107. All were females, age between 17-21 years up. Methods and criteria used in this study were those described in the second edition of the World Health Organization Manual, Oral health survey-Basic Method (1977). The survey was divided into 2 parts. The first part was surveyed before oral health instruction and dental treatment, while the second part was survey after having got one year of oral health instruction and dental treatment. Results revealed that the components influenced upon dental services of 1 the second group were the family income per month and their over confidence of having saved from dental caries. For the above reasons, the second group students took the chance to refer that they did not want to have their dental services in every 12 months. For the first part the Mean DMFT were 2.97, while the Mean DMFS were 6.40 surface per person. The second part had their Mean DMFT 3.37, DMFS 6.87 surface per person. The total mean average of DMFT, DMFS of the first part valued less than the second group 0.40 and 0.47. The student caries status and the periodontal status were different from each other in the statistical values. Even though the dental caries got treatment, mostly both groups still needed for 1-surface fillings. For the periodontal disease, it was found out that the first part got soft debris 100%, while the second part had only 71%.(ABSTRACT TRUNCATED AT 250 WORDS)

Roentgenographic observations in 19 cases of tooth roots displacement to the maxillary sinus using 4 technics of periapical, topographic, Waters and panoramic projection. It was indicated that, 1). Left maxillary first molar root was forced into the antrum more frequently than the roots of other teeth. 2). Roots were displaced into sinus more frequently in males than females. 3). To identify the root, panoramic and topographic were helpful projection. Waters projection was of little or no value, for the root fragment. However it is useful in that it may provide indirect confirmatory evidence of an antral perforation and reveals the presence of sinus infection.
