“…This procedure was repeated to obtain buccolingual and mesiodistal sections of each tooth. A measurement line was traced from the reference occlusal plane following the visible canal curvature in the respective CBCT slice (Jeger et al, 2012). The arithmetic mean of the buccolingual and mesiodistal measurements was recorded as the CBCT WL.…”

“…An accurate determination of the working length (WL) is indispensable for successful endodontic treatment (Sjogren et al, 1990;Ng et al, 2008;Jeger et al, 2012;Connert et al, 2014). However, the location of the apical position constitutes a persistent challenge in clinical endodontics.…”

“…for the measurements of anatomic structure of craniofacial region due to its lower radiation doses and quicker image scanning times in comparison with computed tomography (Guijarro-Martinez and Swennen, 2011). While a few studies have evaluated the accuracy or validity of CBCT for measuring the endodontic, no consensus exists WL (Janner et al, 2011;Jeger et al, 2012;Liang et al, 2013;Connert et al, 2014;Lucena et al, 2014): some authors concluded that CBCT can be used to determine the endodontic WL in combination with EAL (Janner et al, 2011), while others stated that the limited CBCT scans can be used for WL measurements (Jeger et al, 2012;Liang et al, 2013). On the other hands, it revealed that electronic measurements were more reliable than CBCT scans for WL determination (Lucena et al, 2014).…”

“…It is generally accepted that CBCT should not be used routinely in endodontics due to its excessive radiation dose compared to intraoral radiography (Rosen et al 2015;AAE and AAOMR Joint Position Statement 2015;AAOMR and AAE 2010;Patel et al 2015). However, it seems that CBCT use expended to almost every daily endodontic procedure (Rosen et al 2017;Metska et al 2014;Liang et al 2013;Jeger et al 2012;Janner et al 2011;Ustun et al 2016). This increased usage of CBCT in endodontic practices raises questions regarding what do we actually know about the benefits and risks of CBCT use for endodontic proposes.…”

What do we (do not) know about the use of cone beam computed tomography in endodontics? A thematic series with a call for scientific evidence

Cone beam computed tomography (CBCT) has become a common diagnostic method in endodontics. However, the current literature provides insufficient information about different aspects that are related to the use of CBCT, such as: the efficacy of CBCT to support the practitioner's clinical decision making and to affect treatment outcomes; about the required training of the practitioner so he can efficiently examine the entire region that appears in the CBCT scan and diagnose abnormalities or possible pathologies; and on the long-term health risks associated with the use of CBCT in endodontics. In addition, CBCT has the strong potential to be used for accurate diagnosis of complete and uneventful healing. In this thematic series, we call for manuscripts that discuss aspects of the use of CBCT in endodontics.

“…Since its first description in 1998, 17 CBCT has become a popular and valuable technique for preoperative diagnosis and various dental indications including dental and maxillofacial traumatology. [18][19][20][21][22][23][24][25][26][27] In a recent study measuring radiation doses of DCG performed using CBCT and multislice CT, the radiation dose levels in mSv to lens, parotid gland, and thyroid gland were substantially less for CBCT. 4 For dental multislice CT exposures, effective doses up to 1 mSv are used, but considerably lower doses are used for single jaw or low-dose protocols.…”

Purpose:To assess the usefulness of cone beam CT (CBCT) for dacryocystography (DCG) using either direct syringing or passive application of contrast medium.Methods: Ten consecutive patients with epiphora who had CBCT-DCG in a sitting position were retrospectively analyzed. CBCT-DCGs were performed using 2 techniques: direct syringing with contrast medium or using the passive technique, where patients received 3 drops of contrast medium into the conjunctival sac before CBCT-DCG. Clinical and radiologic diagnoses were compared for both groups.Results: The 10 patients (men = 3) had a mean age of 63.2 years. Both techniques proved to be simple procedures with good delineation of the bone, soft tissue, and the contrast medium in the lacrimal system. No side effects were noted.Conclusions: CBCT-DCG is a useful alternative to determine the localization of stenosis in patients with chronic epiphora. (Ophthal Plast Reconstr Surg 2014;30:486-491) D acryocystography (DCG) was the first radiologic technique to visualize the nasolacrimal system in patients with epiphora.1 With ongoing technological development, CT 2,3 and MRI have been adapted for DCG. Disadvantages reported with CT-DCG are the lack of a dynamic contrast passage and increased radiation exposure. 4 MRI-DCG can show the function of the nasolacrimal apparatus under physiologic conditions after topical application of a contrast medium and visualizes subtle soft-tissue changes, such as early malignancies.5 Long imaging time, poor delineation of bony ductal components, and lack of anatomical detail has prevented this imaging technique from being routinely used. Both the abovementioned techniques also have the drawback of being performed only in the supine position. The present investigation presents 10 patients diagnosed with epiphora who were evaluated by DCG using cone beam CT (CBCT) with 2 different methods of contrast medium application (direct syringing versus passive drainage of contrast medium) prior to surgical intervention. The primary objective of the present study was to evaluate CBCT-DCG as an alternative to conventional and CT-based DCG and to compare CBCT-DCG findings to clinical findings on syringing of the lacrimal system. PATIENTS AND METHODSPatient Selection. This study comprised 10 consecutive patients referred to the university eye clinic Bern in whom a DCG was necessary: 9 patients with unilateral and 1 patient with bilateral obstruction of the nasolacrimal drainage system. All patients had undergone prior clinical examination by 1 experienced ophthalmologist (M.T.) on the basis of symptoms of unilateral or bilateral epiphora, suggesting unilateral or bilateral obstruction of the nasolacrimal drainage system. The region of obstruction was assessed clinically by syringing of the nasolacrimal system. A Bangerter lacrimal cannula was passed into the punctum and advanced to the medial wall of the lacrimal sac fossa. Irrigation with saline solution ensured a stenosis, and only patients reporting the absence of saline solution in their nasal antr...
