The purpose of this cross-sectional, quantitative study was to evaluate the salivary flow of 20 patients undergoing conventional 2-dimensional radiotherapy in the head and neck region. Unstimulated salivary flow was measured with the spitting technique. In addition, xerostomia was evaluated through the Eisbruch grading system and the Xerostomia Inventory (XI). The patients were evaluated 3 times: DO, before the first radiotherapy session; D17, after the 17th radiotherapy session; and D35, after the last radiotherapy session. Most of the patients in the present study were men (70%). The larynx was the most frequent site of cancer in this sample (45%). The most prevalent oral alteration during radiotherapy was odynophagia (75%). The analysis of subjective symptoms of xerostomia revealed no statistically significant differences (P = 0.059). However, statistically significant differences in the XI were found, with scores increasing from DO to D17 and D35 (P = 0.004). With regard to the objective symptoms of xerostomia, most patients started treatment in grade 1 and remained in the same category at the end of radiation. There was a slight increase in salivary volume during treatment, an atypical finding that can probably be explained by the use of low-level laser, which was applied to prevent oral mucositis in all of the patients. The mean total radiation dose (65 Gy) received by the patients in the present sample did not appear to influence the XI values or salivary volume. The data reinforced the subjective nature of xerostomia, which is not always related to hyposalivation. [ABSTRACT FROM AUTHOR]

Soft tissue infections are characterized by acute inflammation, diffuse edema, and suppuration, and are often associated with symptoms such as malaise, fever, tachycardia, and chills. Necrotizing fasciitis is a destructive bacterial infection affecting subcutaneous tissue and superficial fascia and is associated with high rates of mortality. It usually involves the abdomen and extremities, but it also can occur in the head and neck. Early diagnosis is critical and the most commonly accepted treatment includes radical surgical intervention and administration of broad- spectrum antibiotics. This article reports and discusses the case of a patient with odontogenic cervicofacial necrotizing fasciitis, and emphasizes the importance of early and effective treatment. [ABSTRACT FROM AUTHOR]

This article presents a case report (including the 10-year follow-up) of a 10-year-old patient who suffered displacement of the maxillary right central incisor, intrusion of the maxillary left central incisor, and crown fractures to the mesial angles of these teeth as a result of dental trauma. Treatment involved an interdisciplinary approach that utilized a pediatric dentist, an endodontist, and an orthodontist. [ABSTRACT FROM AUTHOR]

Oral mucoceles are common lesions characterized by accumulation of mucus following rupture of a minor salivary gland duct. However, congenital mucoceles are a rare and distinctive oral condition observed in newborns. This case report details the features of a congenital labial nodule diagnosed as congenital mucocele. These lesions are rare in the oral cavity and should be diagnosed in the delivery room, but many cases are referred for further evaluation. Management is simple, and recurrence is not expected.

A lymphoepithelial cyst (LC) is a rare occurrence in the oral cavity, and is lined by a keratinized stratified squamous epithelium that is surrounded by diffuse lymphoid tissue that often contains lymphoid follicles. The clinical aspect of oral LC includes an asymptomatic yellowish nodule (less than 10 mm) with regular surface and soft consistency. It usually affects the floor of the mouth and the ventral and posterolateral surfaces of the tongue in adult male patients. To date, approximately 280 cases of LC in the oral cavity have been reported in the literature; however, none of them appear bilaterally. This article presents the histopathological and immunohistochemical findings of a unique bilateral LC in the posterolateral region of the tongue. [ABSTRACT FROM AUTHOR]
