Dysphagia and Ingesting Problems

of the current model, the results obtained can be applied clinically to select properly both implant thread depth and body shape design for a foreseeable success of implant therapy.Background The location of the inferior alveolar nerve (IAN) is generally constant in fully grown mandibles. If we know its average distance from the lower border of the mandible, available bone length from the crest of the edentulous ridge can be estimated by physical measurement of the whole length of mandible in that area. This study aimed to measure the superio-inferior distance of the inferior alveolar nerve (SIDIAN) from the base of the mandible in posterior regions on the right and left side based on cone-beam-computed tomography (CBCT) scans and to evaluate gender and ethnicity-related variations in the Malaysian population. Materials and methods A total of 100 CBCT-Digital Imaging and Communications in Medicine files of the patients of 3 ethnic populations (Malay, Chinese and Indian) between the ages of 18 and 80 years were selected for the study. The files were imported onto the iCAT software. The measurements of the SIDIAN to the lower border of the mandible in molar regions were done on both sides. The data was analysed using t-test, one-way analysis of variance test, and correlation coefficient test via the SPSS software. Results Statistically significant positive correlations were identified between the SIDIAN from the lower border of the mandible in the first and second molar regions within the same side as well as between both sides of the mandible (r ≈ 0.8). There were no statistically significant differences between genders. However, there were statistically significant differences on both molar regions and on both sides in all three ethnic groups (P less then 0.05). In general, the SIDIAN from the lower border of the mandible was greatest amongst Chinese and smallest amongst Indians. Conclusions The strong positive correlations on both sides of the mandible indicate the presence of symmetry. Ethnicity-related variations exist in terms of the location of the IAN in the mandible.Background and aims Dental satisfaction is a multi-dimensional concept, reflecting the total experience of health care and a major driving force of treatment seeking behaviour. At community level, school teachers, being the role model, also play a major role in public health. The aim of this study is to assess the dental satisfaction among school teachers in Hyderabad. Methods A cross-sectional survey was carried out among 515 private school teachers in Hyderabad. The survey tool used was Dental Satisfaction Questionnaire (DSQ) developed by Davies and Ware (1982). Data was analysed with SPSS (Statistical Package for the Social Sciences) version 22. Results The study comprised of 123 (23.9%) males and 392 (76.1%) females. Based on age, significant relation was found only for subscales 'access', 'quality' and 'general satisfaction' (P = 0.01, P = 0.04, P = 0.03 respectively). Though female subjects had higher mean scores for all subscales, significant difference was found only for subscales 'cost', 'quality', 'access total', 'general satisfaction', and 'overall Dental Satisfaction Index' (DSI) (P less then 0.001, P = 0.001, P = 0.008, P less then 0.001, P = 0.001 respectively). Subjects who had visited a dentist had higher mean scores and significant relation was found for subscales 'access' and 'general satisfaction' (P = 0.04, P = 0.04 respectively). Furthermore, subjects who visited a private practitioner had higher mean scores for most of the subscales. Conclusion Female subjects, subjects who had dental visit and those who had visited a private practitioner had higher dental satisfaction. Moreover, age and recent dental visit did not show any effect on dental satisfaction.Objectives The present research was carried out with an aim to estimate and correlate chronological age and estimated age by Kvaal's Method in North Indian population using digital panoramic radiography. Further, the study was an attempt to evaluate the reliability of Kvaal's method for age estimation and to arrive at a population-specific regression equation. Materials and method One hundred digital orthopantomograms of participants aged between 20 and 70 years of age were selected. The evaluation of 6 teeth according to Kvaal's method was carried out using measure tool of Sidexis Software (provided by the manufacturer). Correlation coefficient was carried out between chronological age and estimated age and further regression analysis was carried out for obtaining a population specific regression equation. Results It was observed that coefficient of determination (R2) is highest (0.223) for mandibular canine which indicates that age can be better estimated with this particular tooth. Conclusion It was observed that large variations between the chronological and estimated age were not found. Also, Kvaal's formula proved accurate for estimating age using all the six selected teeth. https://www.selleckchem.com/products/AZD6244.html Thus, it was concluded that mandibular canine would be the better tooth for age estimation, followed by maxillary second premolar and maxillary three teeth taken together.Objective To assess the dental caries experience, clinical consequences of untreated dental caries, and associated factors among 6-13 years school going children in Tiruvallur taluk of Tiruvallur district, Tamil Nadu. Materials and methods The study population included a sample of 1,060 study subjects, aged 6-13 years from both government and private schools. The subjects were interviewed regarding oral hygiene practices, diet, dental visits, body mass index, income of the parents using a closed-ended questionnaire. Caries experience was assessed by recording the Pulpitis, Ulceration, Fistula, Abscess (DMFT)/dmft score and untreated carious lesion was assessed using Pulpitis, Ulceration, Fistula, Abscess (PUFA)/pufa index. Pearson's Chi-square test, independent sample t-test, Kendal tau correlation and binary logistic regression were performed to determine the relationship between DMFT, dmft, PUFA, pufa scores, and various independent factors. Result Among the study subjects, the mean DMFT and dmft scores were 0.
