Salivary gland choristoma in the buccinator muscle: A case report and literature review.

Unlabelled: Salivary gland choristoma (SGCh) is defined as the presence of normal salivary tissue in an abnormal location. It is a rare entity in oral and maxillofacial region and its ethiology is unknown. The typical presentation of salivary gland heterotopia is an asymptomatic mass that may or may not produce saliva.

Prevalence of complications after the oral rehabilitation with implant-supported hybrid prostheses.

Objectives: Assess the main problems referred by the patients and observed by the professionals after the bucodental rehabilitation with an implant-supported hybrid prothesis.

Patients And Methods: A retrospective study was carried out in which there were 43 patients included who were visited in the Department of Oral Surgery and Orofacial Implantology of University of Barcelona Dental School for one year. An oral rehabilitation with an implant-supported hybrid prosthesis was made to those patients.

Validation of a computer-assisted system on classifying lower third molars.

Objectives: The present study evaluates the reliability of the Radio Memory® software (Radio Memory; Belo Horizonte, Brasil.) on classifying lower third molars, analyzing intra- and interexaminer agreement of the results.

Study Design: An observational, descriptive study of 280 lower third molars was made.

Effectiveness of substituting cyclosporin A with tacrolimus in reducing gingival overgrowth in renal transplant patients.

Objectives: This study aims to evaluate the effectiveness of periodontal therapy combined with tacrolimus in the suppression of gingival overgrowth (GO) and the effect on GO of changing from cyclosporin A to tacrolimus.

Patients And Methods: Sixteen renal transplant patients, averaging 52 years of age, whose kidney function was stable and were receiving treatment with cyclosporin A, were randomly assigned to one of two groups. In the experimental group, patients were instructed in oral hygiene and underwent periodontal treatment, whereas in the control group, only oral hygiene instructions were given.

Minor salivary gland tumors: A clinicopathological study of 18 cases.

Introduction: Minor salivary gland tumors (MSGTs) are infrequent, representing 10-15% of all salivary neoplasms. Despite this low frequency, MSGTs conform a heterogeneous group of neoplasms characterized by a broad range of histological types.

Patients And Method: We identified cases of MSGT in a retrospective study of the biopsies made in the period 1997-2007 in the Service of Oral Surgery (Dental Clinic of the University of Barcelona, Spain).

Nasopalatine duct cyst: report of 22 cases and review of the literature.

Objectives: Nasopalatine duct cysts (NPDCs) are the most common developmental, epithelial and non-odontogenic cysts of the maxillae. The present study describes the clinicopathological characteristics of 22 NPDCs and discusses their etiology, incidence, treatment and prognosis, with a review of the literature on the subject.

Study Design: A retrospective observational study was made comprising a period of 36 years (1970-2006), and yielding a series of 22 patients with histopathological confirmation of NPDC.

Evaluation of intraexaminer and interexaminer agreement on classifying lower third molars according to the systems of Pell and Gregory and of Winter.

Purpose: This study evaluated the intraexaminer and interexaminer reproducibility of 2 systems (Pell and Gregory [P&G] and Winter) for classifying the anatomic position of third molars (M3s) and compared these 2 traditional classification systems with a novel computer-based system (Radio Memory software; Belo Horizonte, Brazil).

Materials And Methods: Using a descriptive observational study design, we enrolled a sample of 4 surgeons who evaluated M3 position on panoramic radiographs. They classified M3 position (P&G) and inclination (Winter) on 2 different occasions separated by 15 days.

Comparison of two needle models in terms of bevel deformation during truncal block of the inferior alveolar nerve.

Objectives: To evaluate the differences in terms of bevel deformation between two types of needle of the same length and external caliber, but with different internal diameters, during truncal block of the inferior alveolar nerve.

Study Design: Four operators performed truncal block of the inferior alveolar nerve and infiltrating anesthesia of the buccal nerve for the extraction of a lower third molar in 266 patients. The truncal block was carried out using a standard 27G x 35 mm needle with an internal caliber of 0.

Influence of lower third molar position on the incidence of preoperative complications.

Objective: The present study sought to relate the clinical outcome of mandibular third molar impaction surgery to the orthopanoramic radiographically determined position of the affected teeth based on the classifications of Pell and Gregory, and Winter.

Study Design: A retrospective study was made of 165 patients undergoing the surgical extraction of lower third molars at School of Dentistry of the University of Barcelona, Barcelona, Spain. The positions of the 259 extracted third molars were documented according to the classifications of Pell and Gregory, and Winter, together with the type of mucosal and bony coverage involved.
