Objectives: The aim of this study was to investigate the essential services, importance, interval of examinations, and role of dental hygienists in children's family dentistry program. Methods: A total of 124 participants completed a self-administered questionnaire. The data were analyzed using independent t-test, and ANOVA, and Pearson correlation analysis. Results: All participants stated that oral examination and panoramic radiography are required; children should be educated about brushing, use of oral products, and regular check-ups; and preventive treatments such as molar sealants and prophylaxis should be offered. They stated that light-curing resins and glass ionomer fillings should be offered in treatment services. They stated that examination intervals should be shorter for education and prevention rather than treatment. Dental hygiene students were more likely than dentists and dental hygienists to say that the program was more important. There was a correlation between oral examinations and education and treatment, and between essential services and their importance. Conclusions: Services considered essential and important should be provided first, education and prevention should be provided more frequently than treatment, and their importance should be emphasized not only to dental hygiene students but also to dental hygienists and dentists who are the main providers of services.

The mental foramen and anterior loop of the mandibular canal are important landmarks for mandibular surgical procedures. The purpose of this study was to analyze the shape and position of the mental foramen and anterior loop of the mandibular canal on the computed tomography (CT) images, and apply the results clinically. CT images of 96 patients (33 male, 36 female, age range 17~43 years, mean $24.6{\pm}4.99$ years) were enrolled. The horizontal and vertical position of the mental foramen, as well as the distance from the root apices were measured. The distance of the anterior loop of the mandibular canal to the root apices, and the buccal angle were measured. The mental foramen was found mostly below the second premolar observed in 81 cases (46.0%), between the first and second premolars in 67 cases (38.0%), and between the second premolar and first molar in 19 cases (10.2%). The mean distance between the mental foramen and the lower border of the mandible was $12.20{\pm}1.77$ mm, the mean distance between the mental foramen and root apex was $5.16{\pm}0.98$ mm. The mean distance of the anterior loop of the mandibular canal was $5.80{\pm}2.00$ mm. The buccal angle measured at $47.7{\pm}9.07^{\circ}$. The distance between the root apex and mental foramen measured as $5.16{\pm}0.98$ mm on panoramic radiography, and $6.2{\pm}3.07$ mm on CT. The mean distance between the mental foramen and mandibular canal was $5.39{\pm}1.62$ mm. When performing surgical procedures such as installing dental implants, it is important to minimize surgical trauma, especially the risk of damage to the mental nerve. To optimize the surgical outcome, a careful assessment of the shape and position of the mental foramen and the anterior loop of the mandibular canal must be made. CT images are useful for finding such anatomic structures.

There is tremendous variability in the ways patients present with taste problems. Because of complex and multifactorial etiological background, it is not simple to evaluate patients with taste disorders. Accurate assessment of patients' status by prudent, thorough history taking and symptom analysis is the most essential for exact diagnosis of taste disorders. The aim of this study was to investigate the clinical characteristics of patients with taste problems as a primary complaint. Consecutive series of 50 patients (12 males and 38 females, mean age $53.6\;{\pm}\;14.7$ years) were included for the present study. All subjects were requested to complete a comprehensive questionnaire. Clinical evaluation procedures included oral examination, interview, questionnaire analysis, panoramic radiography, blood test and measurement of salivary flow rate. The obtained results were as follows: 1. Among the patients, 36 patients (72%) complained of oral mucosal pain or burning sensation. Of these patients, 18 patients (36%) were diagnosed as burning mouth syndrome. 2. Nineteen patients (38%) complained of subjective oral dryness. The flow rate of unstimulated whole saliva was less than 0.1 mL/min in 14 patients (28%) and 17 (34%) had a stimulated whole salivary flow rate of less than 0.5 mL/min. 3. Among the types of taste disorders, hypogeusia, the most frequently reported, was found in 25 patients (50%), dysgeusia in 18 patients (36%), phantogeusia in 15 patients (30%), hypergeusia in 10 patients (20%), and ageusia in 5 patients (10%). Nineteen patients (38%) reported more than one type of taste disorder and the most frequent combination was dysgeusia + hypogeusia (n=6, 12%). 4. Based on data from the medical and dental histories and examinations, the patients were assigned to 12 probable causal categories. Taste disorders due to oral mucosal diseases and idiopathic taste disorder were the most frequent (n=9; 18%, each), followed by psychogenic taste disorder (n=8; 16%), drug-induced taste disorder (n=7; 14%), and taste disorder due to dry mouth (n=6; 12%). These 5 categories of taste disorder accounted for 78% of all cases in this study.
