Öğe Age estimation by measuring maxillary canine pulp/tooth volume ratio on cone beam CT images with two different voxel sizes(Taylor & Francis Ltd, 2020) Adışen, Mehmet Zahit; Keleş, Aydan; Yörübulut, Serap; Nalcaci, RanaThe aim of this study is to estimate age by measuring maxillary canine pulp/tooth volume ratio using CBCT images with a voxel resolution of 0.2 mm and 0.4 mm. This study was performed on CBCT images of 131 individuals between 17 and 75 years of age with fully erupted maxillary canine teeth. DICOM data were transferred to 3D-Doctor software, and pulp and tooth surfaces at each 0.2 mm or 0.4 mm axial section were manually drawn. Measurements in CBCT panoramic sections were also performed using Kvaal's method. Pearson's correlation coefficient was used to determine the relationship between pulp/tooth measurements and age. Results show that all measurements, except pulp/tooth length volume (R), are associated with age and that pulp/tooth volume (PV/TV) has the highest correlation with age (r = -0.486). Explanatory coefficient (R-2) of the regression model based on PV/TV is 0.236. There is no statistically significant difference between estimated and chronological ages across different gender and voxel groups (p>0.05). Regression models based on different voxel sizes are statistically significant for age estimation for both voxel groups. The present results should be tested on a wider patient population with evenly distributed samples to determine optimum voxel resolution for age estimation.Öğe Age estimation using maxillary canine pulp/tooth area ratio, with an application of Kvaal's methods on digital orthopantomographs in a Turkish sample(Taylor & Francis Ltd, 2014) Misirlioglu, Melda; Nalcaci, Rana; Adisen, Mehmet Zahit; Yilmaz, Selmi; Yorubulut, SerapThe present study was designed to test the applicability of Kvaal's method on digital orthopantomographs and to develop a new formula measuring pulp/tooth area ratio from periapical X-rays in a group of individuals living in Central Anatolia. Orthopantomographs and periapical X-rays of 114 patients aged between 17-72 years were selected. According to reported technique, three mandibular teeth were evaluated in each orthopantomogram with Kvaal's method. Additionally, the pulp/tooth area ratio was measured on periapical X-rays of maxillary canine. Correlations between real age and morphological variables were calculated for all teeth using Pearson's correlation coefficient. Kvaal's method on digital panoramic radiographs gave acceptable results (standard deviation, SD = 5.9 to 7.9 years) that were close to the original. In addition, regression equations were developed to estimate age from morphological variables and the best results were achieved using the regression equation for the maxillary canine with a pulp/tooth area ratio (standard error of estimate, SEE = +/- 6.75; coefficient of determination R-2 = 0.67). There was no significant difference between observed and estimated age for age groups and gender based on the established regression equations. With this particular study group, the equations presented in the study gave more accurate results than Kvaal's original equations and may be considered more suitable for a Turkish population.Öğe Correlation of upper airway radiographic measurements with risk status for obstructive sleep apnea syndrome in young dental patients(Elsevier Science Inc, 2017) Adisen, Mehmet Zahit; Misirlioglu, Melda; Yorubulut, Serap; Nalcaci, RanaObjective. The aim of the present study is to compare radiographic measurements of the upper airway (UA) in young adult patients with different levels of risk status for obstructive sleep apnea syndrome. Study Design. The study included 50 patients between 18 and 30 years of age who were referred for dental examination and evaluation of impacted third molars. Case record forms, including habit history, along with the Berlin Questionnaire and the Epworth Sleepiness Scale, were completed by the patients and their relatives. According to the answers, 25 low-risk patients and 25 high-risk patients were selected. Cephalometric radiographs and cone beam computed radiography images were obtained for radiographic analysis when the patients were admitted into the study. Results. There were significant differences in body mass index, neck circumference measurements, Epworth score, and smoking status between risk groups. There were significant differences for UA measurements on radiographic evaluation. Body mass index (BMI) was found to be correlated positively with neck circumference and Epworth scores and negatively with UA measurements for all patients. Velopharyngeal measurements showed the highest correlation with Epworth scores, BMI, and neck circumference. Conclusions. The radiographic findings correlated with the survey results. Our data suggest that radiographic measurements of UA may be used as a predictor of risk for obstructive sleep apnea syndrome in a young population.Öğe Evaluation of oral malodor in children(Mosby-Elsevier, 2008) Nalcaci, Rana; Soenmez, Isil SarogluObjective. The aim of this study was to assess oral malodor in highly caries-active children aged 7-15 years, analyze its association with oral malodor parameters, and investigate whether oral hygiene practices and orodental treatments can decrease the effect of oral malodor. Study design. The study included a total of 30 subjects with high caries activity (11 boys and 19 girls), mean age 10.5 +/- 2.4 years, who were living in Kirikkale, Middle Anatolia, Turkey. Oral malodor assessment was carried out by portable sulfide monitor and organoleptic method. A self-administered structured questionnaire was given to the participants. The baseline and final measurements were taken for both malodor-related parameters (volatile sulfur compounds [VSCs] and organoleptic ratings) and dental parameters (tongue coating scores [TCS], plaque index [PI], dental index [DFS + DMFS], community periodontal index of treatment needs [CPITN]). Analysis included frequency, cross-tabulations, analysis of variance, independent-samples t test, and paired t test. Odds ratios of VSC-related factors were also calculated. Significance was set at the 5% level. Results. Gender, DFS + DMFS, and frequency of toothbrushing were not found to be significantly correlated with either VSC levels in mouth air or organoleptic ratings (P > .05). However, tongue coating (P = .003), CPITN (P = .014), PI (P = .017), and age (P = .053) were significantly correlated with VSC levels in mouth air. Regarding the final recordings, significant correlation (P < .001) was found between VSC levels and TCS. Also, significant differences were found between baseline and final measurements in both oral malodor parameters and dental parameters (TCS, CPITN, and PI; P < .001). Conclusions. These results revealed that oral malodor in children is related to periodontal parameters and especially tongue coating. Moreover, malodor parameters were improved by increased awareness of the importance of oral hygiene.Öğe Evaluation of panoramic radiography measures for identifying reduced bone mineral density in elderly(Gunes Kitabevi Ltd Sti, 2010) Nalcaci, Rana; Baran, Ilgi; Orkun, Sevim; Tosun, Aliye; Misirlioglu, MeldaIntroduction: The purpose of this study was to assess the validity of panoramic based indices (Mandibular cortical index, cortical width, panoramic mandibular index, and mandibular ratio) and to determine whether they correlate with bone mineral density in elderly. Materials and Method: The participants of this study were 120 patients; 53 males (45-83 years old, mean: 61.6 +/- 10.02) and 67 females (42-81 years old, mean: 60.58 +/- 9.15). Mandibular indices and number of teeth were measured and evaluated from panoramic radiographs. Bone mineral density (BMD) at the lumbar spine was measured by dual energy X-ray absorptiometry. BMD values were categorized as normal (T-score greater than -1.0), and as indicative of osteopenia (T-score -1.0 to -2.5) or osteoporosis (T-score less than -2.5) according to the World Health Organization classification. Results: There were statistically significant correlations between bone mineral density and sex, cortical width, mandibular ratio and mandibular cortical index (p<0.05). However, there were no significant correlations between panoramic mandibular index and bone mineral density. Also, there were significant correlations between mandibular cortical index and panoramic mandibular index (p<0.01), cortical width (p<0.05), mandibular ratio (p<0.05) and the number of mandibular (p<0.01) and maxillary teeth (p<0.05). However, there was no statistical significant difference between the mandibular cortical index and age (p>0.05). Conclusion: Mandibular cortical index can be used for identifying subjects with low bone mass, allowing the dentists to have sufficient clinical and radiographic information to play a useful role in screening for individuals with osteoporosis.Öğe Evaluation of the oral health status of the people aged 65 years and over living in near rural district of Middle Anatolia, Turkey(Elsevier Ireland Ltd, 2007) Nalcaci, Rana; Erdemir, Ebru Olgun; Baran, İlgiThe aim of this study was to assess the oral health status of aged 65 years and over, and evaluate the level of edentulousness and study the factors that could have an influence on edentulism. The participants of this study were 215 patients; 94 males (47.3%) and 121 females (56.3%), aged 65 years and over. Each subject underwent a comprehensive dental and radiographic examination by one examiner. Periodontal attachment loss observed in the panoramic radiographs was divided into three diagnostic categories: infrabony defects, horizontal bone loss, and furcation lesions. The number of teeth with apical periodontitis lesions, the number of carious teeth, and restorations, type of dentures and wear duration, intrabony root remains, impacted teeth, smoking status, educational level and self-reported medical history of the participants were recorded. Extent of tooth loss was significantly higher in females than males and increased with increasing age (p < 0.05). Tooth loss was significantly associated with educational levels; lower literacy level was found to be associated with a higher number of missing teeth (p < 0.01). Also, as the educational levels of the participants increased, the number of infrabony defects, furcation lesions and number of carious teeth decreased (p < 0.05). Low literacy level and female gender are found to be high-risk groups for tooth loss. Community-based oral disease prevention programs should be implemented to reduce the risk for tooth loss in this population. (C) 2006 Elsevier Ireland Ltd.

Subjects who neither reported systemic disorders nor medication use were included in the study. The participants of this study were 254 healthy subjects, 116 males (mean age: 63.2 +/- 7.2 years) and 138 females (mean age: 61.9 +/- 6.8 years), all aged 55 years and above. A self-administered structured questionnaire on SRH and PTD was given to the participants. Each subject underwent a comprehensive dental examination by one of the examiners. The number of carious teeth, number of restorations, type of dentures (fixed-partial, removable-partial or complete dentures) and wear duration, and tongue coating status were recorded. Associations of the categorical background variables (age, gender, smoking status, tooth brushing frequency) with SRH and PTD were examined using the chi(2)-test. Spearman's rho correlation coefficient was used to analyze the relationship between taste disturbance and SRH with relevant variables (p < 0.05). The prevalence of SRH was 28.3% and the prevalence of PTD was 8.3%. Use of the toothbrush less than once daily was the factor most strongly associated with SRH. Of the individuals with SRH, 73.6% reported subjective oral dryness (p < 0.001) and 9.7% had burning mouth (p = 0.008). Of the individuals with PTD, 71.4% reported subjective oral dryness (p = 0.003) and 14.3% had burning mouth (p = 0.019). Age (p < 0.05), denture type (p < 0.001), tongue coating (p < 0.001), frequency of tooth brushing (p < 0.000 for SRH and p < 0.05 for PTD) were significantly associated with SRH and PTD. Educational level of the participants was significantly different for SRH (p < 0.05). Gender was not found to be associated with either SRH or PTD (p > 0.05). We concluded that the factors most strongly associated with SRH and PTD were subjective oral dryness, tongue coating, inadequate oral hygiene practice and partial and/or complete denture wear. Other factors with significant associations included older age and lower education levels. Smoking was found to be associated with SRH. (c) 2007 Elsevier Ireland Ltd.

Settings and Design: The study was conducted with 1,125 patients who applied to the school of dentistry for routine dental examinations. The authors collect information with a 20-item written questionnaire from the participants about oral cancer risk factors, epidemiology, etiology, and signs and symptoms. Statistical Analysis: Descriptive statistics of demographic variables and other data were reported as means and percentages. Statistical analysis was performed by means of SPSS 11.0 statistical package. Results: Overall, only 48.9% of all patients showed awareness of oral cancer, with awareness especially poor among lower socioeconomic groups. Awareness of oral cancer risk factors and signs and symptoms did not vary significantly between men and women (P > 0.5); however, older participants (aged 40-64 years) were more familiar with oral cancer signs than younger participants. More than half of all participants (56.8%) were unaware of the common clinical presentations of oral cancer. Conclusions: The results of this survey showed knowledge regarding oral cancer to be quite low. Thus, educational programs are needed to increase public awareness about oral cancer, and dentists should request patients undergo examinations for oral cancer to ensure early detection.Öğe Oral malodor and removable complete dentures in the elderly(Mosby-Elsevier, 2008) Nalcaci, Rana; Baran, IlgiObjective. The objectives of this study were to assess oral malodor in patients with removable complete dentures and analyze its association with age, sex, subjective oral dryness, burning mouth, tongue coating, and overnight denture wear in elderly subjects. Study design. The study comprised 105 complete denture wearers ( 56 male, 49 female) between the ages of 50 and 78 from the province of Kirikkale in the Central Anatolia Region of Turkey. Oral malodor was assessed using a portable sulfide monitor. Participants were given a self-administered, structured questionnaire. Baseline and final volatile sulfur compound (VSC) levels and tongue-coating scores (TCS) were measured. Analysis included frequency, cross-tabulations, ANOVA, and independent sample and paired t tests. Odds ratios of VSC-related factors were also calculated. A P value less than .05 was considered statistically significant. Results. There was no significant correlation found between age, gender, smoking, existence of a medical condition, or regular use of medication and VSC levels in mouth air ( P >.05). However, educational level ( P <.05), oral dryness ( P <.05), burning mouth ( P <.05), overnight denture wear ( P <.01), and TCS ( P <.001) were found to be significantly correlated with VSC levels. Significant differences were also found between baseline and final measurements of both VSC levels and TCS ( P <.01). Conclusion. This study found the accumulation of bacterial plaque on the tongue, oral dryness, burning mouth, overnight denture wear, and lower educational levels to be significantly related to oral malodor. Following tongue care maintenance and overnight removal of dentures, patients' oral malodor levels decreased significantly.Öğe A possible association of idiopathic osteosclerosis with excessive occlusal forces(Quintessence Publishing Co Inc, 2014) Misirlioglu, Melda; Nalcaci, Rana; Baran, Ilgi; Adisen, Mehmet Zahit; Yilmaz, SelmiObjectives: The aim of the study was to determine the relationship between idiopathic osteosclerotic lesions and occlusal forces using the T-Scan II computerized occlusal analysis device, and to test the sensitivity of the system in occlusal analysis. Method and Materials: The study was conducted with 21 volunteers with idiopathic osteosclerosis (IO; 14 women, 7 men) aged between 17 and 62 years (mean 29.95). For every patient, seven or eight recordings were made with the T-Scan II occlusal analysis device in maximum intercuspation, and the last two (excluding any with technical problems) were chosen for evaluation. For each lesion-related area, the distribution of high occlusal forces from two different movies was analyzed. Results: In 18 patients (85.71%), lesions were observed in an area of high occlusal force, and in 13 patients (61.9%), the lesions were located at the first area subjected to high occlusal forces. The percentage distribution of high forces at a lesion related area ranged from 0% to 88%. On average, the high forces at an osteosclerotic lesion area accounted for 20% of the maximum total force. No statistical differences were observed between the measurements of the two selected recordings (P > .05). Conclusion: The findings of this study suggest a possible relationship between IO and occlusal forces and primary contacts. T-Scan II was found to be a successful diagnostic device for detecting primary contacts and excessive occlusal forces.Öğe Self-reported denture hygiene habits and oral tissue conditions of complete denture wearers(Elsevier Ireland Ltd, 2009) Baran, Ilgi; Nalcaci, RanaThe aim of the study was to examine the influence of denture hygiene on the development and intensity of denture stomatitis and traumatic ulcers and their relationship to age, gender, educational level, smoking status, age of the denture, denture hygiene habits and denture-wearing behavior. The study population comprised 310 complete denture (CD) wearers (159 males and 151 females) aged 60-85 living in Kirikkale, Turkey. Denture hygiene habits were assessed and recorded, and any relationships between denture hygiene habits and the condition of oral tissue were assessed. The majority (48.4%) of participants reported cleaning their dentures with a toothbrush and toothpaste and 45.2% with a toothbrush only. Less than half (44.8%) removed their dentures overnight. Stornatitis was observed in 35.8% and traumatic ulcers in 29% of patients. A positive relationship was observed between poor denture hygiene habits and the presence of denture-related stomatitis and traumatic ulcers. The degree of denture hygiene was significantly associated with age, sex, education, general health status, smoking status, self-perception of halitosis, overnight denture removal and denture immersion habits.

The first part of the questionnaire was comprised of 20 questions. It was designed in four different sections as: (i) general socio-demographic factors, (ii) general health, (iii) experience and use of dental and denture care, and (iv) anamnestic sign and symptoms of temporomandibular disorders (TMD). A statistical analysis system (SAS) was used for data management and analysis. Patient-reported problems were studied using the item list contained in the Turkish version of the oral health impact profile (OHIP) in a convenience sample of 136 prosthodontic patients before (m(0)), 1 month after (m(1)), and 12 months (m(2)) after treatment were then examined by using two-way ANOVA with repeated measurement. Differences in OHRQoL were present when item-specific prevalence was stratified by time of total scores; gender, residential area, working status, self-reported general health, smoking status, denture type, importance of the convenient dental care, trauma story, self-reported TMD/pain, and self-reported TMD/difficulty opening mouth wide. At baseline, the most prevalent frequently reported problems "difficulties chewing'' (49.3%), "digestion worse'' (40.4%), "take longer to complete a meal'' (36%), "food catching'' (30.9%), and "dentures not fitting'' (29.4%), and m2 the most prevalent frequently reported problems were "avoid going out'' (25%), "difficulties chewing'' (17.6), "sore jaw'' (15.5%), and "take longer to complete a meal'' (14%). The study confirmed that denture status is by far the strongest predictor of impaired OHRQoL compared to socio-demographic factors. Subjects with strong or moderate values had significantly fewer oral health-related problems (OHIP-extent) of time of total scores. The number of problems decreased substantially after prosthodontic treatment. The profile of pretreatment and post-treatment problems differed substantially, but in general, only a few problems remained after adaptation to new dentures. (C) 2010 Elsevier Ireland Ltd.

Materials and Method. The subjects of this study were 100 patients; 48 males (mean age: 60.52 +/- 7.98) and 52 females (mean age: 61.44 +/- 8.06), with removable dentures. The study group were evaluated in two groups; with complete (n=53) and removable partial denture (n=47) in terms of their socio-economic status, general and oral health and temporamandibular disorders. Statistical analysis included t-test and chi-square tests. Results: Statistically significant differences between socio-economic status, gender, age, occupational, general and oral health conditions were found between the groups. Younger females (SO years old) had significantly more frequent temporomandibular disorder symptoms. Variables related to impaired general and oral health were more common in the group with reported temporomandibular disorder problems, whereas satisfaction with received dental care and with denture was lower. Conclusion: Individuals who reported temporomandibular disorder symptoms differed significantly from those without temporomandibular disorder symptoms in socio-economic status, general and oral health symptoms, dental conditions and satisfaction with their denture.
