Evaluation of reasons for extraction of crowned teeth: A prospective study at a university clinic.
Summary of "Evaluation of reasons for extraction of crowned teeth: A prospective study at a university clinic."
Abstract Objective. The aim of this study was to determine and classify the major reasons for extraction of teeth with full crowns belonging to patients admitted to a university clinic within a specific time frame. Methods. Two hundred and eight extracted teeth with full crown belonging to 75 patients were included. Apart from demographic information, reasons for presenting to the hospital, the major reason for extraction, the type of the crown (single crown, bridge abutment, abutment for removable prosthesis), presence of posts, age of restorations, presence of an endodontic treatment and quality were recorded. Comparable data were statistically analyzed using the chi-square test. Results. Forty-three (57.3%) of the patients were females, whereas 32 (42.7%) were males with an average age of 63.21 ± 13.56. A statistically significant relationship was determined between age groups and rate of extractions, with the lowest extractions detected in the 35-44 years age group and the highest in the 55-64 years age group (p = 0.001). Tooth mobility was the predominant reason for patients' initial presentation (52.9%). The most encountered reason for extraction was periodontal reasons with a prevalence of 59.1%, followed by caries (26.9%) and periapical lesions (12%); 35.6% of extracted teeth had endodontic treatment. Sixty teeth (81.1%) had incomplete root fillings. There was a significant relationship between extractions and incomplete root fillings (p = 0.001). Conclusion. Studies comprising other faculty clinics as well as general practices will be complementary in making more generalized statements regarding the etiology of extractions of crowned teeth.

Medical and Biotech [MESH] Definitions
The selective extraction of deciduous teeth during the stage of mixed dentition in accordance with the shedding and eruption of the teeth. It is done over an extended period to allow autonomous adjustment to relieve crowding of the dental arches during the eruption of the lateral incisors, canines, and premolars, eventually involving the extraction of the first premolar teeth. (Dorland, 28th ed)
Orthodontic Space Closure
Therapeutic closure of spaces caused by the extraction of teeth, the congenital absence of teeth, or the excessive space between teeth.
Denture, Partial, Immediate
A partial denture constructed before the teeth it replaces are removed. It is then inserted immediately after the removal of the natural teeth for functional and cosmetic reasons during the healing process. It is to be replaced later by the fitted partial denture.
Total lack of teeth through disease or extraction.
Analytic Sample Preparation Methods
Use of various chemical separation and extraction methods, such as SOLID PHASE EXTRACTION; CHROMATOGRAPHY; and SUPERCRITICAL FLUID EXTRACTION; to prepare samples for analytical measurement of components.
Abstract Aim. To describe the pattern of presentation of carious permanent teeth with pulp exposure and to determine factors associated with choice of treatment for such teeth. Materials and methods....
Oral disease and subsequent cardiovascular disease in people with type 2 diabetes: a prospective cohort study based on the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified-Release Controlled Evaluation (ADVANCE) trial.
AIMS/HYPOTHESIS: While there are plausible biological mechanisms linking oral health with cardiovascular disease (CVD) and mortality rates, no study, to our knowledge, has examined this association in...
Objective: To investigate the class, type, position, diagnosis and most common procedures used in the surgical removal of third molars, and evaluate the sex and age distribution in a representative sa...
Natal teeth are defined as those present in the mouth at birth. They are uncommon and most frequently occur in the anterior mandible as a pair of primary incisors. They are usually small and poorly de...
Although more people are retaining increasing numbers of their natural teeth into older ages, approximately 30-40% of persons over the age of 75 years in Western countries are edentulous. The causes a...
When a tooth is extracted the ridge of bone that held the tooth in place begins to heal and over time new bone grows to fill the empty space left by the missing tooth. Sometimes this proce...
The purpose of this study is to determine whether pulp chamber opening and drainage on wisdom teeth with acute pulpitis before the extraction could reduce postoperative pain so beneficial...
It has been shown through research that alveolar ridges (Part of jaw bone holding teeth) tend to lose width and height after extraction of teeth. Lost in height and width of the ridge can...
Paracetamol is commonly used to reduce pain after operations. Recently anaesthetists have been using bigger doses of paracetamol because it has been suggested that bigger doses will work...
The purpose of this study is to investigate how effective and cost saving 1-deamino-8-D-arginine vasopressin (desmopressin, DDAVP) is as opposed to the transfusion of blood products in pre...
