Association between maxillary sinus mucosal thickening and periapical pathology - a CBCT study

Aim: Association between maxillary sinus mucosa/ thickening and periapical pathology - A CBCT study

Objective: To assess the relation between sinus mucosa/ thickening and periapical lesion, to assess anatomic position of root tips with periapical lesion and to correlate age and prevalence of maxillary sinus mucosa/ thickening

Study Design: This retrospective study analysed 100 CBCT scans of patients between 25-75 years enrolled at a CBCT centre in Bhopal, India. The images were acquired using Sirona's Orthophos SL [70 Kv and 8 mA]. Two oral and maxillofacial radiologists examined all images to evaluate the objectives of the study

Results: The gap or space between the lesion and sinus floor was seen in 48% patients, the lesion contact with the sinus floor was seen in 36% patients, the lesion entered the sinus floor was seen in 16% patients. The prevalence of maxillary sinus mucosa/ thickening in our study increased dramatically as the degree of periapical pathology increased. The relationship between position of root tips with periapical lesion, was also assessed

Conclusion: It can be concluded that there is a strong correlation between maxillary sinus mucosa/ thickening due to periapical pathology

Cone-beam computed tomography: Time to move from ALARA to ALADA

Cone-beam computed tomography (CBCT) is routinely recommended for dental diagnosis and treatment planning. CBCT exposes patients to less radiation than does conventional CT. Still, lack of proper education among dentists and specialists is resulting in improper referral for CBCT. In addition, aiming to generate high-quality images, operators may increase the radiation dose, which can expose the patient to unnecessary risk. This letter advocates appropriate radiation dosing during CBCT to the benefit of both patients and dentists, and supports moving from the concept of "as low as reasonably achievable" (ALARA) to "as low as diagnostically acceptable" (ALADA).

Accessory mental foramina detection by cone beam Ct in Indian population

The purpose of the present study was to assess the accessory mental foramen using cone-beam computed tomography [CBCT] images in Indian population. A total of 100 patients were enrolled in this retrospective study at 3D Facial Imaging Centre, Nashik, India. The mental and accessory mental foramina, which show continuity with the mandibular canal, were assessed using axial and cross-sectional, 2-dimensional CBCT images. The sizes of the mental and accessory mental foramina were measured and statistically analyzed. Also, the distance between the mental and accessory mental foramina was measured. The accessory mental foramen was observed in 8.4% of patients. There was no significant difference regarding the sizes of the mental foramen between accessory mental foramen presence and absence. Also, the mean distance between the mental and accessory mental foramina was 5.3mm. The accessory mental foramen, which shows continuity with the mandibular canal, could be observed in 8.4% of the subjects using CBCT

Squamous papilloma: case report and review of literature / 国际口腔科学杂志·英文版

Squamous papillomas are common lesions of the oral mucosa with a predilection for the mucosa of the hard and soft palate. As an oral lesion, it raises concern because of its clinical appearance, which may mimic exophytic carcinoma, verrucous carcinoma or condyloma acuminatum. Its pathogenesis is related to human papilloma virus but there is controversy regarding its viral origin. We present a case of squamous papilloma presenting as oral lesion along with a review of the literature.
