Osteomas are benign, asymptomatic fibro-osseous tumors that are most commonly observed in the paranasal sinuses and sometimes are found in imaging examinations that were taken for other reasons. Giant osteomas are rarely found in the frontal and ethmoid sinuses but, when they are, they may cause intracranial and orbital complications. The aims of this case report are to describe a frontoethmoid osteoma in a 40-year-old woman, discuss the characteristics of this lesion through cone beam computed tomography (CBCT) imaging, and review the options for treatment. ⋯ The patient did not report any pain. Based on the physical and imaging characteristics of the mass, the location and size of the lesion, and the patient's age, the diagnosis was a giant frontoethmoid osteoma. Due to its enhanced field of view, CBCT may enable earlier diagnosis of lesions that affect the maxillofacial region.

The primary purpose of this study was to evaluate the prevalence of inferior alveolar nerve (IAN) bifurcations through the utilization of cone beam computed tomography (CBCT). The secondary purposes of this study were to analyze the average distance from the main trunk to its branch at the greatest point, to calculate the average distance of the bifid IAN from the apices of the teeth, and to determine the appropriate classification for each IAN bifid nerve according to the types described by Nortjé et al: type 1, 2 canals originating from a single foramen with a narrower inferior canal; type 2, 2 canals originating from a single foramen with a superior canal extending to the second or third molar; type 3, 2 canals of equal size that arise from 2 mental foramina that may link into a single canal near the molars. Examination of 194 CBCT scans revealed that IAN bifurcations were present in 13.4% (n = 26) of the study population. ⋯ For right bifurcated IANs, the average GDN was 4.01 mm, and the average NAP was 4.85 mm. Fourteen bifid nerves were type 1, and 16 were type 2. Preoperative CBCT studies can determine the presence of a bifurcated IAN, thereby reducing the chances of neurologic damage.

This study examined pediatric dentists' perspectives on the types of dental services general dentists provide to children who are 0-3 years old. A web-based survey was sent to 5185 pediatric dentists and 769 (14.8%) responded. Among the respondents, 58% agreed with general dentists' providing an age 1 dental visit. ⋯ Those respondents who taught pediatric dentistry full time were more likely to agree with general dentists' providing an age 1 dental visit (P = 0.0088). Those who reported that their own dental school had adequately prepared them for this type of age 1 visit were also more in agreement (P < 0.0001). The results of this study promote better understanding of pediatric dentists' perceptions of the level of collaboration between general dentists and pediatric dentists; the types of oral health services general dentists can provide for children aged 0-3 years; and the anticipated level of competency of entry-level general dentists.

Prescription drug abuse is on the rise, causing detrimental health consequences and taking lives. Since dentists comprise a large percentage of opioid prescribers, they should be well educated on the uses and effects of opioids. This article discusses the consequences of long-term opioid use, how to identify signs of dependence, and how to prevent future abuse.
