Investigation of the maxillary lateral incisor agenesis and associated dental anomalies in an orthodontic patient population
2011
CEYLAN, Ismail/0000-0002-8693-4175; KAMAK, HASAN/0000-0003-1910-3694 WOS: 000314401800025 PubMed: 22549676 Objectives: The aim of this study was to investigate the prevalence of maxillary lateral incisor (MLI) agenesis and associated dental anomalies as well as skeletal patterns in an orthodontic population, and then to compare it with the prevalence of these anomalies in the general population. Study Design: The material of the present study included the records of the 3872 orthodontic patients. The followings were recorded for each subject with the agenesis of MLI: Age, sex, unilateral or bilateral absence, anterior-posterior skeletal relationship of the maxilla and mandible, and presence…
Accidental dental displacement into the maxillary sinus during extraction maneuvers: a case series
2020
Background The aims of this study were to describe the clinical findings of patients that suffered teeth displacement into the maxillary sinus, and to report the surgical technique used to solve this complication. Material and Methods A retrospective observational study was conducted involving patients that suffered a displacement of teeth into the maxillary sinus. Demographic and clinical data were recorded from the affected patients and a descriptive statistical analysis was made of the study variables. Results A total of nine patients were enrolled, six males (66.7%) and three females (33.3%), with a mean age of 36.0 years (range 22-54). In five patients (55.5%) the displaced teeth remai…
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 …
Efficacy and complications associated with a modified inferior alveolar nerve block technique. A randomized, triple-blind clinical trial
2014
Objectives: To compare the efficacy and complication rates of two different techniques for inferior alveolar nerve blocks (IANB). Study Design: A randomized, triple-blind clinical trial comprising 109 patients who required lower third molar removal was performed. In the control group, all patients received an IANB using the conventional Halsted technique, whereas in the experimental group, a modified technique using a more inferior injection point was performed. Results: A total of 100 patients were randomized. The modified technique group showed a significantly higher onset time in the lower lip and chin area, and was frequently associated to a lingual electric discharge sensation. Three f…
Prevalence of Musculoskeletal Disorders among Dentists and Dental Students in Germany
2020
Background: Dentists are at a higher risk of suffering from musculoskeletal disorders (MSD) than the general population. However, the latest study investigating MSD in the dental profession in Germany was published about 20 years ago. Therefore, the aim of this study was to reveal the current prevalence of MSD in dentists and dental students in Germany. Methods: The final study size contained 450 (287 f/163 m) subjects of different areas of specialization. The age of the participants ranged from 23 to 75 years. The questionnaire consisted of a modified version of the Nordic Questionnaire, work-related questions from the latest questionnaire of German dentists, typical medical conditions and…
Periodontal health and esthetic results in impacted teeth exposed by apically positioned flap technique.
2010
Objectives: This study evaluates the periodontal health status and the esthetic results of teeth subjected to orthodontic traction, after their exposure by an apically positioned flap. Study design: Fifteen patients were included in the study, ages between 11 and 28 years old. The fenestrated teeth and their homologous contralateral normally erupted teeth, used as control, were evaluated. Results: Statistically significant differences were found in the position of the gingival margin (p = 0.005), with an average distance between cemento-enamel junction (CEJ) and gingival margin of 2.47 mm (SD 1.19) in control teeth and of 1 mm (SD 1.31) in the operated teeth, and in the depth of palatal pro…
An experimental study of the esthetic effect of facial profiles
1998
In this study good-looking "male" and "female" as well as ugly facial profiles were shaped by 104 lay persons using an especially constructed device according to specific instructions. These profiles were photographed and subsequently evaluated using a series of parameters from soft tissue profile analyses. Although some significant mean value differences were found between the good-looking and ugly profile variants, they were not substantial. In contrast, markedly significant differences were revealed between the variances of all variables. In some instances the variance of the ugly profiles was more than 3 to 4 times higher than that of the good-looking profiles. These findings were convi…
Parental satisfaction with children's primary dental care in Valencia, Spain.
2011
Aim To evaluate parents’ satisfaction with the dental care that their children received in a primary dental care unit in Valencia, Spain. Methods A cross-sectional study was designed. Parents were given a self-administered questionnaire with questions on accessibility, information received from the dentist and hygienist, staff interest in their child, dentist's and hygienist's apparent professional competence, handling of the child's behaviour, cleanliness of the office (surgery), overall parent satisfaction, parent's and child's age, and parental educational level. The chi-square test was used to assess overall parental satisfaction and the other study variables. For the multivariant study…
Influence of soft tissue grafting, orofacial implant position, and angulation on facial hard and soft tissue thickness at immediately inserted and pr…
2018
Background Resorption of hard and soft tissues following immediate implant insertion is frequently reported. Data regarding the influencing factors on facial tissue thickness are rare. Purpose This retrospective study investigated the impact of connective tissue grafting, the orofacial angulation and position of immediately inserted and provisionalized implants on the facial hard and soft tissue thickness in the anterior maxilla within a 1- to 5-year follow-up. Material and methods Implants with the prerequisite of having preoperative and postoperative cone beam computed tomography (CBCT) and a follow-up of 1 to 5 years were included. Facial bone deficiencies were grafted flaplessly with au…
