Retrospective evaluation of the clinical performance of direct composite restorations using the snow-plow technique : up to 4 years follow-up
2019
Background To evaluate the clinical performance of direct composite restorations using the snowplow technique with up to 4 years of follow-up. Material and methods In this retrospective study, 101 class II composite restorations which were placed in permanent molars (n = 19) and premolars (n = 82) in 85 patients by the snowplow technique, were evaluated according to the modified USPHS criteria. A Kaplan-Meier analysis with a 95% confidence level was used to calculate the survival probability. Results Of the 101 teeth examined, tooth failure was identified in 8 teeth due to secondary caries (3%), marginal gap (2%), marginal discoloration (1%) and restoration breakdown (2%) which required rep…
Aerosols generation using Er,Cr:YSGG laser compared to rotary instruments in conservative dentistry: A preliminary study
2021
Background In restorative dentistry, the use of high-speed air turbine, which generates aerosols, can be associated with the transmission of airborne diseases. New laser technologies could be useful in reducing the amount of aerosols, but there is a lack of scientific research on this topic. Material and methods This is a descriptive study to analyze the amount of aerosols produced after class I cavity preparation using high-speed air turbine (group 1) and Er,Cr:YSGG laser with two different parameters (groups 2 and 3). Fluorescein dye was incorporated into the coolant reservoir in order to visualize the production of aerosols during each procedure. Tooth preparation was performed in a typo…

Application of propolis extract, nanovitamin C and nanovitamin E to prevent alveolar osteitis after impacted lower third molar surgery. A randomized,…
2020
Background Propolis has anti-inflammatory, analgesic and healing properties. The purpose of this study was to determine whether a gel containing 2% of propolis extract, 0.2% of ascorbic acid and 0.2% of tocopherol acetate is effective in preventing surgical complications related to impacted lower third molar extractions. Material and Methods A randomized, double-blind, split-mouth study was performed. Fifteen patients were recruited who needed bilateral impacted lower third molar extractions with a similar surgical difficulty. A test or placebo gel was administered randomly inside post-extraction sockets. Each patient was instructed to apply the gel 3 times/day in the surgical wound for a w…
Wilson maxillary curve analyzed by cbct a study on normocclusion and malocclusion individuals
2013
The anatomy of dental compensation curve in the frontal plane described by George H. Wilson is one of the occlusal determinants of orthodontic treatment. However, there is few published comparing malocclusion and normocclusion individuals. Objectives: The aim of this study is to compare the curve of Wilson at first and second maxillary molars, normocclusion pattern and malocclusion pattern, with and without bilateral posterior crossbite, using angular references in CBCT studies. Material and Methods: We analyzed 10 cases of malocclusion with bilateral posterior crossbite, 10 cases of malocclusion without bilateral posterior crossbite and 10 cases with non orthodontic normocclusion (patients…
Clinician-related factors behind the decision to extract an asymptomatic lower third molar. A cross-sectional study based on Spanish and Portuguese d…
2017
Background: Scientific literature estimates that around 18 to 40 % of asymptomatic third molars are extracted. The aims of the present study were to determine the indications for extraction of asymptomatic lower third molars in a sample of Spanish and Portuguese dentists, and to relate these indications to the clinicians’ training and professional experience. Material and Methods: A survey consisting of 15 cases of asymptomatic lower third molars was emailed to Portuguese and Spanish dentists. The clinicians were asked to assess the level of difficulty of the extractions and to make a reasoned recommendation based on the panoramic radiographs, gender and age of the patients. Results: 381 cl…

Anxiety before extraction of impacted lower third molars.
2014
Objetives: Assess levels of trait anxiety, state anxiety and dental anxiety before extraction of lower third molars and check the correlation and reliability of the scales used for the measurement of preoperative anxiety. Study D esign: A prospective study of patients treated with extraction of a lower third molar between September 2010 to December 2010 was carried out. A total of 125 patients were included in the study. All of them were patients of the Oral Surgery and Implantology Department (Valencia University Medical and Dental School, Valencia, Spain). Before surgery, patients had to complete a preoperative protocol with 4 scales: the STAI-T (State-Trait Anxiety Inventory-Trait) for m…
Incidence of impacted and supernumerary teeth-a radiographic study in a North Greek population.
2010
Objectives: The aim of the present study was to investigate the prevalence of impacted and supernumerary teeth, apart from third molars. Study design: This was a retrospective study of 1.239 panoramic radiographs taken of patients who presented to the Department of Dentoalveolar Surgery, Implantology and Radiology at the School of Dentistry of the Aristotle University of Thessaloniki, Greece between 1991 and 1999. The panoramic radiographs and dental records were reviewed in order to determine whether there were impacted or supernumerary teeth. Observations were also made on the space in dentition, corresponding to the position of each impacted tooth, the lack of space for tooth eruption, t…

No. of bitstreams: 0 Previous issue date: 2021-01-01 Background: This study aimed to conduct a randomized prospective study about the efficacy of etodolac and ibuprofen on trismus, pain and edema regarding gender of patients submitted to impacted lower third molar teeth extraction. Material and Methods: Thirty patients aging between 16 and 35 year-old were submitted to the exodontia of impacted lower third molars. During the postoperative period, patients received nine ibuprofen (600 mg) or etodolac (300 mg) pills via oral administration immediately after surgery and repeated doses every eight hours during three days. Patients were eva…
