Effect of pre-operatory low-level laser therapy on pain, swelling, and trismus associated with third-molar surgery
2017
Background The extraction of impacted third molars is commonly associated to pain, edema, trismus, limited jaw opening and movements. The aim of this retrospective study is to verify if pre-surgical low-level laser therapy (LLLT) associated with the extraction of impacted lower third molars could add benefits to the postoperative symptoms respect LLLT performed only after surgery. Material and Methods Data from 45 patients subjected to a surgical extraction of lower third molars were pooled and divided into three groups. Patients that received only routine management were inserted in the control group. Group 1, were patients that received LLLT immediately after surgery and at 24 hours. In g…

No. of bitstreams: 0 Previous issue date: 2020-07-01 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Background: As third molar surgery is the most commonly procedure performed in Dentistry and has been accompanied by serious postoperative disorders such as pain edema and trismus, the study aimed to evaluate if ultrasound device would be able to reduce such postoperative features. The aim of this study was to assess the effects of soft tissue flap elevation, osteotomy and odontosection using piezosurgery versus conventional technique in mandibular third molar extractions. Material and Methods: Twenty patients with impacte…
Presence of palm oil in foodstuffs: consumers' perception
2019
Purpose The purpose of this paper is to determine the presence of palm oil in food products on sale, and to study and compare consumers’ opinions about this oil type in Spain (importing country) and Peru (producing country). Design/methodology/approach Recent news published in both countries, which could influence consumer perceptions, were analysed. A study on the labelling of foodstuffs in Spain was carried out, as was a survey with Spanish and Peruvian consumers. Findings Palm oil was found in a large number of products and in a wide range of foods, especially those from the bakery sector. The percentages of saturated fats varied substantially within the same product type. Spanish consu…
Prevalence of impacted teeth and supernumerary teeth by radiographic evaluation in three Latin American countries: A cross-sectional study
2021
Background Supernumerary teeth are those that exceed the usual dental formula. There are different classifications depending on their anatomical location, shape and number. The objective of this study was to determine the prevalence of impacted and supernumerary teeth in a sample of panoramic radiographs from three Latin American countries. Material and Methods A retrospective and cross-sectional study with a quantitative approach, in which the radiographic observation and analysis of 2000 panoramic radiographs, provided by different radiological centers in Peru, Colombia and Bolivia were performed. An examiner, specialized in Stomatology and Oral Surgery, carried out the radiographic analy…
Comparative analysis of impacted upper canines: Panoramic radiograph Vs Cone Beam Computed Tomography.
2016
Background The use of CBCT exam in the study of IMC is not new. However, it's still not known in what specific aspects CBCT exam shows a better result than then conventional exams. The aim of this study was to compare and conclude in what way the opinion regarding upper canine impaction differed when observing a panoramic image compared to the observation of a set of CBCT reconstructions. Material and Methods Twenty patients (10 males and 10 females) with a total of 28 impacted maxillary canines were identified from the database of the Department of Dentistry, Faculty of Medicine, University of Coimbra. For each canine, two different images were available: a panoramic image and a set of CBC…
Does muscular activity related to vertical facial divergence influence the time needed for orthodontic extrusion of palatally impacted maxillary cani…
2018
Background The aim of the present study was to evaluate if the different muscular activity correlated to different degrees of facial divergence has an effect on the time needed to extrude a palatally impacted maxillary canine. Material and methods Twenty-six patients were retrospectively selected, all treated with a specific cantilever appliance that allows extrusion of the impacted canine applying a physiologic amount of force below 0.6 N in a predictable way. For all the patients, pre-treatment cephalometric tracings were used to evaluate facial divergence through the FMA angle, the angle between the maxillary and mandibular plane, and the angles between the occlusal plane and either the …
Spontaneous eruption of severely impacted teeth : the report of two cases
2019
The unerupted and impacted tooth is a common problem and the reason for many orthodontic and pediatric dental referrals, yet the approach to their management is still an area of controversy. This article presents two cases of severely impacted teeth that spontaneously erupted in the maxillary and mandibular arches. The first patient, a 9-year-old girl, presented a severe impaction of mandibular right and left second premolars. The second patient, a 7-year-old girl, presented with a severely impacted maxillary central incisor. In both cases, the teeth spontaneously erupted into excellent positions without surgical procedures and orthodontic traction. This raises important questions concernin…
Dental implants placement in paranoid squizofrenic patient with obsessive-compulsive disorder: A case report
2017
Background Paranoid schizophrenia is a mental illness that involves no observable anatomical alteration. Main characteristic affects the personality of the individual, as well as areas of his own psychology. Case report A 33-year-old man with paranoid schizophrenia and obsessive-compulsive disorder in treatment with Haloperidol, Oxcarbazepine, Olanzapine and Seroquel is presented. Dental exploration showed widespread decay mostly cervical with numerous root fragments, agenesis of lateral incisors, impacted wisdom teeth, missing teeth and malocclusion. Treatment plan included restoration of teeth decay, extractions of root fragments and implant-supported prostheses in bilateral upper lateral…
Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risk…
2018
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on risks and risk-outcome associations. With each annual GBD study, we update the GBD CRA to incorporate improved methods, new risks and risk-outcome pairs, and new data on risk exposure levels and risk-outcome associations. METHODS: We used the CRA framework developed for previous iterations of GBD to estimate levels and trends in exposure, attributable deaths, and attributable disability-adjusted life-years (DALYs), by age group, sex, year, and location for 84 b…
