ABSTRACT Orofacial odontogenic infection, although arises from dental origin, can extend into the facial spaces and lead to debilitating complications. This study analysed the clinical pattern and management of orofacial odontogenic infection in a tertiary hospital namely Hospital Raja Permaisuri Bainun in Perak, Malaysia. We investigated any associations between socio-demographic factors, diabetic, comorbidities, smoking, pregnancy, antibiotic resistance, number and type of space infected towards prolonged hospital stay. All adult patients with orofacial odontogenic infections treated by Department of Oral and Maxillofacial Surgery from 2014 to 2018 were included. Clinical patterns were evaluated. Statistical analysis was performed to measure various variables towards prolonged hospital stay. A total of 154 patients (78 male, 76 female) were included in this study with mean age of 37.95 ± 14.9 years. Key factors of orofacial odontogenic infection requiring admissions were swelling, pain, trismus, odynophagia, reduced oral intake, raised floor of mouth and dyspnea. Among inpatients, three factors were significantly associated with prolonged hospital stay, namely antibiotic resistance, multiple space and secondary space infection. Local prevalence data was reported. Pus culture and sensitivity tests were recommended for all inpatients with multiple space and secondary space involvement, in order to rule out antibiotic resistance and to improve recovery rate.

A study aimed at determining the major causes and influence of age, gender on the endodontic diseases. 141 patients (male: 103, female: 38) with 196 teeth participated to the study. The results have shown that 89% patients were at ages of 40 and older, the major cause of the endodontic diseases were dental decay (42%), other lesions without dental decay (30%), periodontitis (20%) and others (8%). The lesions occurred in the teeth of upper curve more frequently than these in the inferior teeth (61% compared with 31% respectively) did. There was significant difference of lesions between teeth (cheek teeth: 72%; small cheek teeth: 16%, anterior teeth and canine teeth: 12%)

The oral community survey in Yen Bai was conducted in 1997. 804 pupils (girls and boys aged 6 to 11 years old) who were ethnic minority primary pupils were examined for Dental caries and periodontal status and some of concerned elements using standard 1988 WHO basis oral health. Survey method and test question. Percentage of pupil affected by Dental carries of milk teeth: 41.79%, highest in Kinh group, lowest in Tay group. It is not alien from delta area and highland. Periodontal status: percentage of pupils who had CPI1=4.48%; CPI2=47.39%. It is not alien from delta area and highland but it is alien among nations, highest CPI2 was in H’Mong group. It needs a project to prevent reasonably oral diseases.

The purpose of this study was to investigate the characteristiss of korean multi-rooted teeth extracted by periodontal disease. A total of 182 extracted multi-rooted teeth were examined. The distance from the cementoenamel junction(CEJ) to the root groove and from the CEJ to the root division was measured. The frequency of the root grooves were calculated. The results are as follows : 1. Distances from CEJ to the root groove were 1.53, 1.60mm for maxillary first premolars mesial, distal sides, 1.26, 1.38, 1.75mm for maxillary first molars buccal, mesial, distal sides, 1.38, 1.71, 1.41mm for maxillary second molars buccal, mesial, distal sides, 0.98, 0.99mm for mandibular first molars buccal , lingual sides and 1.28, 1.35mm for mandibular second molars buccal, lingual sides. 2. The frequency of the root grooves were 17.4, 30.4% for maxillary first premolars mesial, distal sides, 44.4, 84.1, 67.5% for maxillary first molars buccal, mesial, distal sides, 100, 90.3, 90.3% for maxillary second molars buccal, mesial, distal sides, 42.9, 77.8% for mandibular first molars buccal, lingual sides and 90.6% for mandibular second molars buccal, lingual sides. 3. Distances from CEJ to the root division were 6.8, 7.2mm for maxillary first premolars mesial, distal sides, 3.3, 4.38, 4.34mm for maxillary first molars buccal, mesial, distal sides, 3.67, 4.8, 4.07mm for maxillary second molars buccal, mesial, distal sides, 3.1, 3.89mm for mandibular first molars buccal, lingual sides and 3.2, 4.06mm for mandibular second molars buccal, lingual sides.

The presence of an ectopic supernumerary tooth in the nose is an uncommon phenomenon. A supernumerary tooth may be asymptomatic but must be given special attention as it has the potential to cause significant morbidity. Bilateral intranasal supernumerary teeth are an extremely rare disease entity. We report the clinical and radiologic findings of bilateral ectopic supernumerary teeth erupted from the nasal floor.

All contours of the restoration not directly related to occlusion are related to the gingival tissues only. And proper contour of restoration is essential for the health of the periodontal tissues. But there are so many controversies about the contour of the restoration, and there is no uniform agreement in the literature as to which contour of restoration is best for periodontium. In general, the contour of restoration means the supragingival contour only but in the case of the intracrevicular restorative procedure the subgingival contour of restoration must be considered. Because a portion of the restoration is placed in a gingival sulcus which is extremely vulnerable to periodontal disease. In this article the concepts or theories of the supragingival contour, the subgingival contour, and the emergence profile were discussed. The contour of the restoration and the biotype of the periodontium must be considered in intracrevicular restorative procedure. And sufficient tooth preparation is important factor to develop the proper contour of restoration which is kind to periodontium.

Periodontal disease is caused by accumulation of bacterial plaque. For the reason, plaque control is essential to control and prevent periodontal disease. Among the plaque control methods, mechanical plaque removal, tooth brushing is common and reliable. But it depends on individual habituation and their manner. To catch up the gap of effectiveness, lots of oral hygiene appliances have been developing. Powered toothbrush is the most interesting field and is showing on the market with various motion type. This study was performed to compare clinical effects of plaque removal between powered toothbrush and manual toothbrush. The results were as follows: 1. Plaque index was decreased statistically after the brushing than before the brushing in every group.(p<0.05) 2. Comparing plaque index among the three groups before and after brushing, there were no statistically significant differences. 3. Interproximal plaque index was decreased statistically after the brushing than before the brushing in every group.(p<0.05) 4. Comparing interproximal plaque index among the three groups before and after brushing, there were no statistically significant differences.
