    The mental foramen and lingual vascular canals are related to vessels and nerves in the mandibular body. The aim of the present study was to determine the number and location of these structures and to make measurements of them. The archived Multidetector Computed Tomography images of 100 adult (15- to 70-year-old) patients were evaluated retrospectively. The diameters of the mental foramens and their distances from the front, back, upper and lower reference points were measured. The distribution of mental foramens with respect to the teeth was also researched. The presence of lingual vascular canals, and the number of median and lateral canals was determined, and the length of the median lingual vascular canals measured. All measurement parameters were analyzed by gender, side and age group. Eleven patients demonstrated a total of 15 accessory mental foramen. Median lingual vascular canals were observed in 100% of cases, with lateral lingual vascular canals determined in 32%. Significant differences were observed in the results of different gender groups (P < 0.05); in contrast, no significant difference was observed related with age or side. Accessory mental foramen was determined mostly in males, and unilaterally on the right side; also, the distances of mental foramen, except the distance from the back border of the mandible (P < 0.05), were found to be higher, bilaterally, in males. Variation of mental foramen, as well as the presence, position and size of lingual vascular canals can be clearly investigated by multidetector computed tomography. A preoperative knowledge of the positions of neurovascular and bone structures is very important for preventing complications that may occur during or after operations.

    Reevaluation of mandibular morphometry according to age, gender, and side
    (LIPPINCOTT WILLIAMS & WILKINS, 2018) Direk, Filiz; Uysal, İsmihan İlknur; Kıvrak, Ali Sami; Ünver Do?an, Nadire; Fazlıoğulları, Zeliha; Karabulut, Ahmet Ka?an
    Aim: This study aims to reevaluation the linear and angular measurements of mandibles with multidetector computed tomography (MDCT) that is a new method and used frequently in recent years. Materials and Methods: The archived MDCT images of 100 adult patients (age range, 15-74 years) without mandibular operation and trauma history were evaluated retrospectively. Mandibular ramus heights, maximal mandibular length, mandibular symphysis height, mandibular angles, and mandibular foramen distance measurements were performed on MDCT images. All measurement parameters were analyzed by gender, age groups, and sides. Results: Mandibular linear length measurements were higher in males than in females (P<0.05). Only mandibular symphysis height was statistically significantly different in age groups (P<0.05). The Angle 1 (gonial angle) was found to be significantly higher in females (P<0.05). The Angle 3 (right condyle-gnathion-left condyle angle) was observed to be significantly higher in the 60+ age group (P<0.05). The 3 of the mandibular foramen measurements (distance from the front edge, distance to gonion, and height of lingula) were found to be higher in males than in females (P<0.05). There were no significant differences according to age groups in these measurements. The lengths of the mandibular canals were higher in males (44.72mm) than in females (41.68mm). There was no statistically significant difference was found between gender, age groups, and sides of mandibular canal length. Conclusion: The MDCT was found to be a reliable method for the detection of mandibular morphometry when compared with the results of other radiographic images studies.

    The effect of ceramic painting on the life satisfaction and cognitive status of older adults residing in a nursing home
    (Lippincott Williams & Wilkıns, 2019) Çetinkaya, Funda; Aşiret, Güler Duru; Direk, Filiz; Ozkanli, Niluefer Nazende
    Objectives: The aim of this experimental study was to assess the cognitive activity and satisfaction with life of older adults in nursing home before and after ceramic painting. Methods: The sample of the survey consisted of 15 older adults each in the intervention and control groups. Data for the study were collected using a questionnaire form developed to determine the sociodemographic characteristics of the older adults, the Mini-Mental State Examination, and the Life Satisfaction Scale. Results: There was a statistically significant increase in the mean Mini-Mental State Examination score of the intervention group compared with the control group at the end of ceramic painting (P < .05). The intervention group had increased average Life Satisfaction Scale scores in the posttest compared with the control group, although the difference was not statistically significant. Conclusions: The results showed that art therapy with ceramic painting was a positive effect on the cognitive levels and quality of life of older adults.
