Two-Dimensional Radiographic Diagnosis of Maxillary Canine Impactions.

The primary aim of this study was to evaluate, using conventional radiographic imaging, the height, angulation, and mesiodistal position of impacted maxillary canines to determine if these variables are significantly associated with the palatal or buccal positioning of the tooth. A retrospective analysis was conducted on all patients diagnosed and treated for at least one impacted maxillary canine over a 4-year period in the Principality of Asturias. The final sample included 159 impacted canines.

Effects of Vape Use on Oral Health: A Review of the Literature.

: The widespread use of tobacco has evolved with the popularity of vapes, especially among young people, despite the lack of clarity in warnings about their risks. Studies indicate the need for more effective communication about the oral risks of vaping. In addition to systemic, respiratory, and cardiovascular effects, vaping is associated with an increased risk of gingivitis and periodontal disease as well as reduced antioxidant capacity of saliva.

Keratocyst Capnocytophaga superinfection.

Introduction: Capnocytophaga spp are Gram-negative bacteria that cause severe infections in immunosuppressed patients. This situation is extremely rare in immunocompetent patients.

Case Report: This clinical report describes the unusual infection of an immunocompetent patient with Capnocytophaga spp.

Intervention to improve awareness of the risk factors for osteonecrosis of the jaw in patients under treatment with bisphosponates. Randomised clinical trial.

Purpose: To evaluate the effectiveness of a health education programme on knowledge and reduction of the risk factors for bisphosphonate-related osteonecrosis of the jaw.

Methods: An experimental study control group without intervention was performed with 60 subjects who had started treatment with bisphosphonates in the University Hospital of León from October to December 2014. Patients in the experimental group received a structured education intervention in two sessions.

Sentinel Node in Oral Cancer: The Nuclear Medicine Aspects. A Survey from the Sentinel European Node Trial.

Purpose: Nuclear imaging plays a crucial role in lymphatic mapping of oral cancer. This evaluation represents a subanalysis of the original multicenter SENT trial data set, involving 434 patients with T1-T2, N0, and M0 oral squamous cell carcinoma. The impact of acquisition techniques, tracer injection timing relative to surgery, and causes of false-negative rate were assessed.

Sentinel European Node Trial (SENT): 3-year results of sentinel node biopsy in oral cancer.

Purpose: Optimum management of the N0 neck is unresolved in oral cancer. Sentinel node biopsy (SNB) can reliably detect microscopic lymph node metastasis. The object of this study was to establish whether the technique was both reliable in staging the N0 neck and a safe oncological procedure in patients with early-stage oral squamous cell carcinoma.

Treatment of oral and oropharyngeal epidermoid carcinomas by means of CO2 laser.

Introduction: The effect of the wide long-wave CO2 laser is the thermal vaporization of the tissues, getting a maximum energy concentration with a minimum of tissue penetration. In oral surgery, it is generally used for the treatment of oral and oropharyngeal small mucous tumors, due to the scarce morbidity that takes place and the absence of reconstructive necessity.

Objective: To analyze the postoperative evolution, in the patients treated by oral and oropharyngeal epidermoid carcinomas, after CO2 laser resection.

Prognostic significance of p53 expression in oral squamous cell carcinoma without neck node metastases.

Background: Aberrations of the p53 gene and overexpression of its protein are widely recognized markers of malignancy including oral squamous cell carcinomas. This study was performed to evaluate the relationship of immunoexpression of p53 protein in series of 91 squamous cell carcinomas of the oral cavity with clinicopathologic parameters and to investigate whether p53 immunoexpression might influence the clinical outcome of the disease.

Methods: From a group of 287 consecutive patients, 91 surgically treated ones were randomly selected.

Neck schwannomas.

Schwannomas are peripheral nerve tumours of nerve sheath origin. Twenty-five to 45 percent of extracranial schwannomas occur in the head and neck region. We present 2 cases of schwannomas that arise from the vagus and cervical plexus.
