Is overweight a risk factor for adverse events during removal of impacted lower third molars?

Being overweight is recognised as a significant risk factor for several morbidities; however, the experience of the dentistry faculties focusing on this population is still low. The aim of the present study was to determine the occurrence of adverse events during removal of impacted lower third molars in overweight patients. A prospective cohort study was carried out involving overweight patients subjected to surgical removal of impacted lower third molar as part of a line of research on third molar surgery.

Assessment of factors associated with surgical difficulty during removal of impacted maxillary third molars.

Purpose: Estimating the difficulty of removing third molars is a common dilemma. However, the estimation of the difficulty associated with maxillary third molar surgery has not yet been defined.

Retrograde migration of a ventriculoperitoneal shunt to the neck after dental treatment.

The ventriculo-peritoneal shunt (VPS) is the technique most often employed for the treatment of hydrocephaly, but may present complications after placement. Retrograde migration of the peritoneal catheter to the cervical region is rarely reported. This manuscript to describes a case of migration of the distal portion of the VPS system to the neck after dental treatment in a child and discusses the possible causes for this complication.

Prevalence and predictive factors of dental anxiety in Brazilian adolescents.

Purpose: The purpose of this study was to determine the prevalence and predicitve factors of dental anxiety among Brazilian adolescents.

[Anxiety regarding dental treatment: prevalence and predictors among Brazilians].

Considering the negative impact anxiety can exert over dental treatment, the scope of this study was to determine the prevalence of predictors of anxiety regarding dental treatment among Brazilians. A cross-sectional study was carried out using the Corah dental anxiety scale to assess the degree of anxiety regarding dental treatment among 3000 patients. The results reveal that two out of every eight Brazilian patients manifest moderate to severe anxiety regarding dental treatment.

Clinical study of hemodynamic changes comparing 4% articaine hydrochloride with 1:100,000 and 1:200,000 epinephrine.

Objective: To evaluate hemodynamic changes with the use of 4% articaine and 2 different concentrations of epinephrine (1:100,000 and 1:200,000) in the surgical removal of symmetrically positioned lower third molars.

Study Design: A prospective, randomized, double-blind clinical trial was carried out involving 42 patients each undergoing 2 surgeries on separate occasions under local anesthesia with 4% articaine and either epinephrine 1:100,000 or 1:200,000. The following parameters were assessed at 4 different moments: systolic, diastolic, and mean blood pressure; heart rate; oxygen saturation; rate pressure product (RPP); and pressure rate quotient (PRQ).

Guided surgery in unusual palatal torus.

Palatine torus is a benign congenital outgrowth of bone that affects the hard palate and palatine processes, resulting from the "overworking" of osteoblasts and bone deposition along the line of the palatine fusion. Surgical excision is the only treatment for torus, and such patients are susceptible to intraoperative and postoperative complications of a traumatic, functional, or infectious nature. This article describes an atypical case of torus palatinus measuring 20.

Brain abscess of odontogenic origin.

Brain abscess is a rare and threatening infection, which is in a suppuration area, caused either by trauma, neurosurgical complication, or by a secondary infection of dental origin complication. The infectious process spread from the start focus can occur in 2 ways: hematogenous or by contiguity. The treatment should ideally be based on the etiological factor excision, combined with drainage and antibiotics as adjuvant; this philosophy is not observed in the reports described in the 1960s, 1970s, and 1980s.

Ameloblastic fibro-odontoma in children: report of 2 cases.

Ameloblastic fibro-odontoma is a rare, mixed, benign, odontogenic tumor of significant prevalence in the mandible, with epithelial and mesenchymal components. It usually affects pediatric patients and is associated with teeth, causing a delay in eruption chronology or an alteration in the dental eruption pathway. It is occasionally diagnosed during radiographic evaluations of these patients.

Assessment of factors associated with surgical difficulty during removal of impacted lower third molars.

Purpose: The aim of the present study was to adjust a multivariate model to explain each of the response variables for the occurrence of surgical difficulty during the removal of impacted lower third molars.

Patients And Methods: A prospective cohort study was carried out involving patients submitted to at least one surgical removal of an impacted lower third molar. A total of 285 patients fulfilled the eligibility criteria and 473 surgeries were performed.

Tooth embedded in tongue following firearm trauma: report of two cases.

Injuries caused by projectiles from firearms involve diverse patterns of dentoalveolar trauma due to the different types of wound and extent of tissue damage. This article reports two cases in which tooth fragments were embedded in the tongue following aggression from a firearm projectile in the facial region. Radiographs confirmed the presence of foreign bodies, which were surgically removed under local anesthesia.

Treatment of large ameloblastic fibroma: a case report.

Ameloblastic fibroma (AF) is an extremely rare true mixed benign tumor that can occur in either the mandible or the maxilla, but is most frequently found in the posterior region of the mandible. It usually occurs in the first two decades of life and is associated with tooth enclosure, causing a delay in eruption or altering the dental eruption sequence. AF is diagnosed on routine radiographic evaluation and is clinically and radiographically similar to ameloblastic fibrodontoma and odontoma, which makes an accurate diagnosis mandatory.

Oral and maxillofacial myiasis associated with epidermoid carcinoma: a case report.

Myiasis is a term derived from the Greek word "myia", meaning invasion of vital tissue of humans or other mammals by fly larvae. The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions, alcoholism and senility.
