Evaluation of enamel pearls by cone-beam computed tomography (CBCT)
2011
Objective: The aim of this study was to evaluate the frequency of enamel pearls according to population, sex and tooth groups on Cone-Beam Computed Tomography (CBCT) or Dental Volumetric Tomography (DVT) scans of patients, retrospectively. Study Design: In this study, 15185 teeth belonging to 768 patients, 430 female and 338 male, was performed cross-sectional examination by CBCT. The volumetric Computed Tomography used in the study is Newton FP based on flat-panel. The data were analyzed with Pearson chi-squared test. Results: Enamel pearls were detected in 36 subjects (4.69%). Of these enamel pearls, 19 were detected in male and 17 were in male. There was no statistically a significant as…
The prevalence of pulp stones in a Turkish population. A radiographic survey
2011
Objectives: The goal of this retrospective study was to determine the prevalence of pulp stones in a Turkish population. Any possible associations between pulp stones and gender, tooth type and dental arch were also evaluated. Study Design: Four hundred and sixty nine patients’ bitewing radiographs which were reached through the patient database of Erciyes University Dentistry School, Department of Oral Diagnosis and Radiology were examined. Of these 469 subjects whose mean age was 24( ± 10.7), 302 were females and 167 were males. A total of 6,926 teeth were examined during this study. Pulp stones were recorded as present or absent and any relations with gender, tooth type and dental arch w…
Morphological and topographical characteristics of posterior supernumerary molar teeth: An epidemiological study on 25,186 subjects
2014
Objectives: To investigate the prevalence , gender difference , arch , morphology and position within the arch of supernumerary molar (SM) teeth in a referred Italian Caucasian population. Study D esign: Records of 25,186 young patients were evaluated. Only data related to supernumerary teeth in the posterior region of the jaws were analyzed. The diagnosis of hyperdontia was formulated during the clinical and radiological examinations based on panoramic radiographs. Statistical analysis was conducted at level of subjects in the assessment of prevalence of SMs and sex ratio. Statistical analysis was conducted at level of teeth according to their morphological and topographic characteristics.…
Cytological changes in the oral mucosa after use of a mouth rinse with alcohol. A prospective double blind control study
2012
Aim: The aim of this preliminary study was to detect cytological changes in the oral mucosa after using a mouth wash with alcohol. Material and Methods: A prospective double-blind, controlled study was performed, for 6 months. Group 1 consisted of 30 subjects who used a mouth rinse with 26.9% of alcohol [Listerine®] and Group 2 consisted of 30 subjects who used a mouth rinse with the same ingredients but with no alcohol. We obtained three cytological samples from the oral mucosa. The presence of cytological atypia, binucleation and karyorrhesis, and type of cells were studied. We also used a fluorescent in situ hybridization technique (FISH) in 15 samples in each group, for the micronucleus…
Risk factors for temporomandibular disorder: Binary logistic regression analysis
2013
Objectives: To analyze the influence of socioeconomic and demographic factors (gender, economic class, age and marital status) on the occurrence of temporomandibular disorder. Study Design: One hundred individuals from urban areas in the city of Recife (Brazil) registered at Family Health Units was examined using Axis I of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/ TMD) which addresses myofascial pain and joint problems (disc displacement, arthralgia, osteoarthritis and oeste - oarthrosis). The Brazilian Economic Classification Criteria (CCEB) was used for the collection of socioeconomic and demographic data. Then, it was categorized as Class A (high social class…
Analysis of 55 cases of adenomatoid odontogenic tumor in an Indian population and review of literature
2021
Background This study reviews the demographic, clinical and radiographic features of adenomatoid odontogenic tumor(AOT) diagnosed in an Indian population over 50 years and also evaluate and compare follicular AOT(F-AOT) and extra-follicular AOT(EF-AOT). Material and Methods 55 diagnosed cases of AOT from 1971-2020 were studied retrospectively. The data regarding the age, sex, location, variant of AOT, duration, clinical features, radiographic appearance, treatment and recurrence were collected and analysed. Results Of the 722 odontogenic tumors diagnosed, 7.6% were AOTs with higher prevalence of extra-follicular (67.3%) than follicular (32.7%) variant. All the tumors were intraosseous with …
Application of an oral health-related quality of life questionnaire in primary care patients with orofacial pain and temporomandibular disorders
2013
Objectives: To examine whether patients who report orofacial pain (OP) and temporomandibular disorders (TMD) have a poorer perception of their oral health-related quality of life and, if so, to what extent, and to analyze the association between oral health perception, sociodemographic variables and reported pain duration. Study Design: 407 patients treated at the OP and TMD units in the Healthcare District of Cordoba, Spain, diagnosed following the standard criteria accepted by the scientific community – the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) – were administered the Spanish version of the Oral Health Impact Profile questionnaire (OHIP-14). Bivariate and …
Tumors of the salivary gland in Mexicans. A retrospective study of 360 cases
2011
Objective: To establish distribution frequency and demographic characteristics of salivary gland tumours (SGT) i6n order to identify possible risk profiles. Design of study: The present report constitutes an eight year retrospective study (January 2000-August 2007). The archives of the Clinical and Experimental Pathology Laboratory (Graduate and Research Division, Dental School, National Autonomous University of Mexico) as well as archives of the Surgical Pathology Service (General Hospital, Mexico City) were subject to revision in order to select all cases where SGT tumour diagnoses were emitted. Age and gender of patients as well as SGT topography were obtained from medical records. Selec…
Localized gingival enlargements. A clinicopathological study of 1187 cases.
2017
Background To describe the incidence, demographic and clinical features of 1187 localized gingival enlargements. Material and Methods 1187 cases of localized gingival enlargements diagnosed during a 20-year period were retrospectively collected. The patients’ gender and age, as well as the main clinical features of the tumors were retrieved from the biopsy report forms. Results The 1187 localized gingival enlargements represented 6.23% of 19.044 biopsies performed during the study period. 756 females and 427 males were affected with a mean age of 41.92±19.68 years.
