Initial Report

Osteomyelitis is one of the most feared sequelae of diabetic foot ulceration, which often leads to lower-extremity amputation and disability. Early diagnosis of osteomyelitis increases the likelihood of successful treatment and may limit the amount of bone resected, preserving ambulatory function. Although a variety of techniques exist for imaging the diabetic foot, standard radiography is still the only in-office imaging modality used today. However, radiographs lack sensitivity and specificity, making it difficult to diagnose bone infection at its early stages. In this report, we describe our initial experience with a cone beam computed tomography (CBCT)–based device, which may serve as an accurate and readily available tool for early diagnosis of osteomyelitis in a patient with diabetes. Two patients with infected diabetic foot ulcers were evaluated for osteomyelitis using radiography and CBCT. Positive imaging findings were confirmed by bone biopsy. In both patients, CBCT captured early osteolytic changes that were not apparent on radiographs, leading to early surgical intervention and successful treatment. The CBCT was helpful in facilitating detection and early clinical intervention for osteomyelitis in two diabetic patients with foot ulcers. These results are encouraging and warrant future evaluation.

Radiographic Interpretation

A radiographic interpretation is essential to the diagnosis of invasive cervical resorption (ICR) and the difficulty in distinguishing this lesion from internal root resorption has been highlighted in the literature. This paper reports the use of cone beam computed tomography (CBCT) in the diagnosis of ICR. The cases reports describe how CBCT can be used to make a differential diagnosis and also show that the use of this technology can provide relevant information on the location and nature of root resorption, which conventional radiographs cannot. As a result, the root canal treatment was not initially considered. The patients will be monitored and will undergo a scan after a short period of time to detect any small changes. It was observed that both cases benefited from CBCT in the diagnosis of ICR, because this imaging modality determined the real extent of resorption and possible points of communication with the periodontal space.

Phantom Head

Background Cone-beam computed tomography (CBCT) is a fast imaging technique with a substantially lower radiation dosage than conventional multidetector computed tomography (MDCT) for sinus imaging. Surgical navigation systems are increasingly being used in endoscopic sinus and skull base surgery, reducing perioperative morbidity. Objective To investigate CBCT as a low-radiation imaging modality for use in surgical navigation. Methods The required field of view was measured from the tip of the nose to the posterior clinoid process anteroposteriorly and the nasolabial angle to the roof of the frontal sinus superoinferiorly on 50 consecutive MDCT scans (male = 25; age = 17–85 years). A phantom head was manufactured by 3-dimensional printing and imaged using 3 CBCT scanners (Carestream, J Morita, and NewTom), a conventional MDCT scanner (Siemens), and highly accurate laser scanner (FARO). The phantom head was registered to 3 surgical navigation systems (Brainlab, Stryker, and Medtronic) using scans from each system. Results The required field of view (mean ± standard deviation) was measured as 107 ± 7.6 mm anteroposteriorly and 90.3 ± 9.6 mm superoinferiorly. Image error deviations from the laser scan (median ± interquartile range) were comparable for MDCT (0.19 ± 0.09 mm) and CBCT (CBCT 1: 0.15 ± 0.11 mm; CBCT 2: 0.33 ± 0.18 mm; and CBCT 3: 0.13 ± 0.13 mm) scanners. Fiducial registration error and target registration error were also comparable for MDCT- and CBCT-based navigation. Conclusion CBCT is a low-radiation preoperative imaging modality suitable for use in surgical navigation.

BACKGROUND Cone beam computed tomography (CBCT) was first introduced in 2008 and has since seen a tremendous growth in both private dental clinics and dental institutions. This has led to the normalization of CBCT use by general dentists. Therefore, it is essential to assess how and why general and specialist dentists use CBCT. The purpose of this study was to assess the knowledge, practice and attitude towards CBCT among general and specialist dentists working in the kingdom of Saudi Arabia. METHODS In this cross-sectional study, a questionnaire was electronically distributed via email and social media from October 2018 to September 2020. The self-administered questionnaire was divided into five segments: demographics, knowledge, current practice, training and attitude. RESULTS A total of 221 dentists filled the questionnaire including 85 general dentists and 135 post graduate students or specialists. The majority of dentists (81.9 %) demonstrated poor knowledge. Orthodontists and endodontists were most aware of CBCT terms. Most dentists (71.5 %) have a CBCT unit in their practice. Only 34.8 % received CBCT training, the majority of which was theoretical. A positive attitude was noted in 83.2 % of dentists by agreeing to a statement regarding CBCT justification. CONCLUSIONS Poor CBCT knowledge was evident in majority of dentists despite having CBCT in their practice. Dentists are highly aware of the importance of CBCT justification and professional interpretation; however, they lack basic knowledge and training related to this imaging modality. This highlights an institutional gap that policy makers should address in order to ensure the highest quality of patient care. KEY WORDS Cone Beam Computed Tomography; CBCT; Survey

Abstract Accurate and early diagnosis of vertical root fractures (VRFs) is imperative to prevent extensive bone loss and unnecessary endodontic and prosthodontic treatments. The aim of this study was to assess the effect of time lapse on the diagnostic accuracy of cone beam computed tomography (CBCT) for VRFs in endodontically treated dog's teeth. Forty-eight incisors and premolars of three adult male dogs underwent root canal therapy. The teeth were assigned to two groups: VRFs were artificially induced in the first group (n=24) while the teeth in the second group remained intact (n=24). The CBCT scans were obtained by NewTom 3G unit immediately after inducing VRFs and after one, two, three, four, eight, 12 and 16 weeks. Three oral and maxillofacial radiologists blinded to the date of radiographs assessed the presence/absence of VRFs on CBCT scans. The sensitivity, specificity and accuracy values were calculated and data were analyzed using SPSS v.16 software and ANOVA. The total accuracy of detection of VRFs immediately after surgery, one, two, three, four, eight, 12 and 16 weeks was 67.3%, 68.7%, 66.6%, 64.6%, 64.5%, 69.4%, 68.7%, 68% respectively. The effect of time lapse on detection of VRFs was not significant (p>0.05). Overall sensitivity, specificity and accuracy of CBCT for detection of VRFs were 74.3%, 62.2%, 67.2% respectively. Cone beam computed tomography is a valuable tool for detection of VRFs. Time lapse (four months) had no effect on detection of VRFs on CBCT scans.

Mid Palatal Suture

Background: Cone beam computed tomography (CBCT) imaging techniques are the recent rage in the field of oral diagnostic imaging modality. It is noninvasive, faster and lacks anatomic superimposition. Earlier maxillary occlusal radiographs were used to assess and evaluate the mid palatal suture, but being a two dimensional imaging modality it could not assess the ossification process which takes place in multiple planes mostly due to curved nature of the palate. In this study we assessed the mid palatal suture morphology and classify them according to the variants using CBCT images. Materials and methods: A total of 200 CBCT scans (95 males and 105 females) were evaluated in the present study from the archives of an imaging center. As per Angelieri classification the midpalatal suture was classified into five categories (A–E) depending on the degree of ossification that had taken place. Statistical analysis was done by Chi Square test using SPSS version 23.0. Results: There is statistically significant difference present in the stages of maturity of mid palatal suture in various age groups with Stage B is most common in Group 1 (50%), Stage C most common in Group 2 (60%) and Group 3 (40%) and Stage E more common in Group 4 (50%). Conclusion: The results of the present study showed a wide variation in the initiation time and the degree of ossification and morphology of the midpalatal suture in different age groups. Although there was an increase in the closure of the suture with aging, age is not a reliable criterion for determining the open or closed nature of the suture. This finding is important in providing an idea as to how diverse is the ossification of maxillary sutures.
