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…
Marsupialization facilitates movement of the cystic lesion-associated deeply impacted mandibular third molar in spite of its mature roots
2017
Background: The odontogenic cystic lesions happened in the angle and ramus region are frequently associated with impacted mandibular third molars. The treatment plan was difficult to work out for the huge cystic lesions with deeply impacted third molars, since the enucleation with simultaneously removing the deeply impacted teeth may cause serious complications. Therefore, the marsupialization of the cystic lesions followed by enucleation with tooth removal has also been advocated. The aim of this study was to explore the movement of cystic lesion-associated deeply impacted mandibular third molars (IMTM) after marsupialization. Material and Methods: Between July 2009 and December 2015, pati…
Ectopic third molar in the mandibular condyle: A review of the literature
2012
Objectives: To evaluate the etiopathogenesis, clinical features, therapeutic options, and surgical approaches for removal of ectopic third molars in the mandibular condyle. Study design: MEDLINE search of articles published on ectopic third molars in the mandibular condyle from 1980 to 2011. 14 well-documented clinical cases from the literature were evaluated together with a new clinical case provided by the authors, representing a sample of 15 patients. Results: We found a mean age at diagnosis of 48.6 years and a higher prevalence in women. In 14 patients, associated radiolucent lesions were diagnosed on radiographic studies and confirmed histopathologically as odontogenic cysts. Clinical…
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…
Sensibility and taste alterations after impacted lower third molar extractions. A prospective cohort study
2012
Objectives: To determine the incidence, severity and duration of lingual tactile and gustatory function impairments after lower third molar removal. Study Design: Prospective cohort study with intra-subject measures of 16 patients undergoing lower third molar extractions. Sensibility and gustatory functions were evaluated in each subject preoperatively, one week and one month after the extraction, using Semmes-Weinstein monofilaments and 5 different concentrations of NaCl, respectively. Additionally, all patients filled a questionnaire to assess subjective perceptions. Results: Although patients did not perceive any sensibility impairments, a statistically significant decrease was detected …
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.…
Complications in third molar removal: A retrospective study of 588 patients
2010
Objectives: Surgical removal of third molars is a regular surgical procedure, which like all operations, may have complications. The purpose of the study was to analyze the incidence of complications and their relationship with the surgical difficulty in a group of 588 patients treated by the same oral and maxillofacial surgeon. Study design: This retrospective cohort study consisted of 1699 third molars (M3) removed between 2005 and 2008. The teeth were grouped into a 6-class scale of surgical difficulty rated according to the surgical procedure description in the patient?s file: I: upper M3 requiring forceps only; II: upper M3 requiring osteotomy; III: upper M3 requiring osteotomy and too…
What are the risk factors for postoperative infections of third molar extraction surgery: A retrospective clinical study-?
2018
Background This study aimed to identify (1) the predilection site of postoperative infection after third molar extraction surgery, (2) risk factors associated with postoperative infection, and (3) the cause of the difference between delayed- and early-onset infections. Material and Methods This retrospective study included 1010 patients (396 male, 614 female) who had ≥1 third molars extracted (2407; 812 maxilla, 1595 mandible). The risk factors were classified as attributes, general health, anatomic, and operative. Outcome variables were delayed- and early-onset infections. Results Postoperative infection was completely absent in the maxilla, and all infections occurred in the mandible, wit…
Mandibular Molar Root Resection Versus Implant Therapy: A Retrospective Nonrandomized Study
2009
AbstractSuccess rates for both periodontal and implant therapy are often dependent on site and tooth type. For periodontally involved mandibular molars, the decision to hemisect or to extract and place an implant is often complicated. The purpose of the present study was to evaluate the outcomes of the aforementioned treatment modalities for mandibular molars in a private practice setting. A retrospective chart review was performed. In one group of patients (n = 32), 56 mandibular first or first and second molars were treated by hemisection (Group H). A second group (n = 28) received 36 implants in the mandible to replace periodontally involved first or first and second molars (Group I). Al…
Morphology and dimensions of the dentogingival unit in the altered passive eruption.
2011
Objetives: This study define altered passive eruption (APE) and evaluate the morphology of the dentogingival unit. Material and Methods: 123 individuals subjected to clinical examination and parallel profile radiography of the upper central incisor. An evaluation was made of the correlation between the clinical diagnosis of APE and the degree of gingival overlap; by using a 19% overlap to define APE (Kappa concordance index = 0.7). The Mann-Whitney / Wilcoxon test was used to identify the variables influencing APE. Results: Statistically significant differences were observed between the teeth with and without APE: gingival width (p = 0.0073), clinical crown length (p = 0.0000), smiling expo…
