The evaluation of apicectomy without retrograde filling in terms of lesion size localization and approximation to the anatomic structures
2018
Background The purpose of this study was to evaluate of the patients who underwent apical resection. Besides assess the classification of resection side, localization, lesion size, approximation of anatomic structures and the purpose of the apical surgery retrospectively. Material and Methods In this stutdy 782 patients and 1191 apical resection applied tooth evaluated. 504 of the patients were famale and 278 were male. Patients age was between 13 and 76 years old and operated between January 2016 and January 2017. The study includes incisor, canine and premolar teeth which had the apical resection as the first time. Operation side evaluated from orthopantomograph and periapical radiographs…
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…
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…
Gastric outlet obstruction in a neonate because of Peutz-Jeghers syndrome
2012
Neonatal detection of Peutz-Jeghers syndrome is unusual with only 2 cases previously reported in the literature. We describe a neonate presenting with gastric outlet obstruction owing to 2 large Peutz-Jeghers polyps. The child's father and grandmother were known to have Peutz-Jeghers syndrome. On the ninth day of life, the infant underwent colonoscopy, abdominal exploration, and complete surgical resection of 3 polyps. The postoperative course was uneventful, and the patient was discharged home at the age of 3 weeks on full oral feeds. This is the first case report of inherited Peutz-Jeghers syndrome causing gastric outlet obstruction in a neonate.
[Myringoplasties. A retrospective analysis of our surgical outcomes].
2010
Objective: The aim of this study was to present myringoplasty case results in our department. Different factors were studied to confirm their prognostic value. Materials and methods: A total of 126 myringoplasties from 2006 until 2010 were reviewed, collecting patient-related details, descriptions of the anatomical defect and the most interesting surgical aspects. Results: Subtotal perforations (35.7%) were the most frequently observed. In 89.7% of the operations, the transcanal approach was preferred. The medial technique (underlay) to the tympanic membrane was the most performed (97.6%). Cartilage was the principal graft used (82.5%). Complete closure of the perforation was obtained in 71…
Oral lichenoid lesions associated with amalgam restorations : a prospective pilot study addressing the adult population of the Basque Country
2011
Oral lichenoid lesions (OLLs) are linked to a heterogeneous group of pathologies involving the oral mucosa that cannot be distinguished from the oral lichen planus excepting the fact that direct causal factors such as silver amalgam restorations (SARs) can be allocated to them. Purpose: To analyze the prevalence of mucosal lesions associated with SAR in a group of SAR carrying patients in the Basque Country. Study D esign: A clinical prospective study was carried out on 100 adult patients over 30 years of age at the UPV/ EHU Clinical Odontology Service whose rear teeth had at least one SAR. Patients were identified and mucosal lesions and amalgam restorations were characterized. Patch tests…
Two-year clinical performance of a packable posterior composite with and without a flowable composite liner
2003
The aim of the study was to evaluate the clinical performance of a packable fine hybrid dental composite (Prodigy Condensable) and the influence of the additional application of a flowable resin composite (Revolution, SDS Kerr) layer on marginal integrity after 2 years in stress-bearing posterior cavities according to the Ryge criteria. In 50 patients (40.5+/-17.5 years of age), 116 class II fillings (metal matrix system, glass ionomer-cement-base in 36%, rubberdam isolation in 70%) were placed, with at least two restorations per patient. The adhesive Optibond Solo Plus was used for all the restorations. In one of the two fillings in each patient, an additional layer of the flowable composi…
Immediate temporary restoration of single-tooth implants : prospective clinical study
2010
Purpose: The goal of this study is to assess the survival, marginal bone loss and complications around sing le-tooth implants on which immediate provisionalization was carried out. Patients and Methods: 78 implant were placed in 57 patients: 56 after extraction and 22 in healed sockets. Immediately after surgery provisional crowns were delivered without contacts in both centric and excursive jaw movements. The final crowns were inserted between 3 to 6 months later. During the study there were 3 x-rays taken per patient. The marginal bone loss was measured and complications were recorded. The statistical analys is of the data was carried out with the STATA 10® software. Results: The mean dur…
Three-year clinical performance of two indirect composite inlays compared to direct composite restorations
2013
Objective: Despite the incremental build-up of resin composite restorations, their polymerization shrinkage during curing presents a serious problem. Indirect composite resin systems represent an alternative in overcoming some of the deficiencies of direct composite restorations. The hypothesis of the present study states that the clinical performance of restorations may be affected by different generation and application techniques. Study Design: Sixty restorations (20 DI system (Coltene/Whaledent AG, Altstatten, Switzerland) composite inlays, 20 Tescera ATL system (BISCO Inc. Schaumburg, Illinois, USA) composite inlays, and 20 direct composites) were applied to premolar teeth in 49 patien…
Endoscopic Procedures through the Foramen Interventriculare of Monro under Stereotactical Conditions
1994
The foramen interventriculare of Monro is an anatomical narrowness for the endoscopic access to the third ventricle. The effective mechanical angle to pass the foramen interventriculare from a frontal bore hole depends on the diameter in the plane of entrance, the depth of the foramen, and the diameter of the endoscope. Under the pathological conditions of a hydrocephalus internus the foramen interventriculare is enlarged. By means of stereotactical guidance, it is possible to reach the third ventricle accurately without damaging anatomical structures around the foramen interventriculare. The endoscopic technique under stereotactical guidance using a rigid endoscope is sufficient and safe t…
