“…The electrical resistance based device “Prepometer™” was found to be an accurate measuring tool for estimation of RDT in comparison to histological sectioning and CBCT methods [ 12 ]. In order to decrease the confounders that could affect its accuracy, young adult and early adult age groups were selected as representative for conditions with normally wide dentinal tubules, less sclerosis and high dentinal fluid [ 27 ] where electrical impedance would be expected to be low [ 5 , 10 ].…”

“…Many invitro studies have used and evaluated the Prepometer™ [ 5 , 9 – 12 ] nevertheless few clinical data are available; [ 8 , 13 ] thus, this clinical study was introduced to help in proving the validity of this device clinically. Also due to the raised importance of patient-reported outcome measures (PROMs) and lack of sufficient knowledge in this area, patient satisfaction regarding the two devices was measured.…”

Background Accurate assessment of remaining dentin thickness (RDT) is paramount for restorative decisions and treatment planning of vital teeth to avoid any pulpal injury. This diagnostic accuracy study compared the validity and patient satisfaction of an electrical impedance based device Prepometer™ (Hager & Werken, Duisburg, Germany) versus intraoral digital radiography for the estimation of remaining dentin thickness in carious posterior permanent teeth. Methods Seventy patients aged 12–25 years with carious occlusal or proximal permanent vital posterior teeth were recruited. Tooth preparation was performed to receive an adhesive restoration. Pre- and post-excavation RDT were measured radiographically by two calibrated raters using the paralleling periapical technique. Prepometer™ measurements were performed by the operator. Patients rated their satisfaction level with each tool on a 4-point Likert scale and 100 mm visual analog scale (VAS). Inter and intragroup comparisons were analyzed using signed rank test, while agreement between devices and observations was tested using weight kappa (WK) coefficient. Results the intergroup comparisons showed that, before and after excavation, there was a significant difference between measurements made by both techniques (p < 0.001). After excavation, there was a weak agreement between measurements (WK = 0.2, p < 0.001), whereas before excavation, the agreement was not statistically significant (p = 0.407). Patients were significantly more satisfied with Prepometer™ based on scales and VAS (p < 0.001). Conclusion Prepometer™ could be a viable clinical tool for determining RDT with high patient satisfaction, while radiographs tended to overestimate RDT in relation to the Prepometer™.

“…The emergence of CBCT has greatly improved the diagnostic success rate of difficult oral cases and promoted the development of oral medicine. Compared with spiral CT, CBCT has the advantages of small voxel, high image spatial resolution, short scanning time, and low radiation dose, so it is widely used in clinical practice [47][48][49][50][51].…”

: Endodontic disease or periapical disease is one of the most common oral diseases in clinic. Root canal therapy (RCT) is currently the most common and effective method for the treatment of endodontic or periapical diseases. Root canal therapy (RCT) is currently the most common and effective method for the treatment of endodontic or periapical diseases. The complex root canal morphology of mandibular first molar is a major challenge for its root canal treatment. The application of nickel-titanium instruments has brought new breakthroughs in root canal therapy, but also brought some new hidden dangers. This article reviews the research status of cone beam computed tomography (CBCT) guided nickel-titanium instruments for mandibular first molar preparation in recent years.

“…CBCT is an innovative 3D imaging modality that provides a non-invasive option to evaluate dental tissues without the superimposition of surrounding structures [Scarfe and Farman, 2008]. In addition, CBCT was found to be more valid and reliable in measuring remaining dentin thickness in deep carious lesions and tertiary dentin thickness than traditional periapical X-rays when compared to histologic assessments [Kamal et al, 2021;Palczewska-Komsa et al, 2022;Sarhan et al, 2022]. Other studies have also shown that CBCT is the imaging modality of choice to evaluate secondary dentin formation in vivo [Tardivo et al, 2011;Ge et al, 2015].…”

Three-Dimensional Assessment of Radiographic Changes after Indirect Pulp Capping Using Silver Diamine Fluoride with or without Potassium Iodide in Young Permanent Teeth (12-Month RCT)

et al. 2023

The aim was to have a three-dimensional evaluation of radiographic changes after indirect pulp capping (IPC) with silver diamine fluoride (SDF) with or without potassium iodide (KI) and resin modified glass ionomer cement (RMGIC) in deep carious young permanent molars using cone beam computed tomography (CBCT). 108 first permanent molars with deep occlusal cavitated caries lesions, in forty-nine 6–9-year-old children, were randomly allocated to one of 3 groups (n=36) and treated with SDF+KI, SDF and RMGIC as IPC materials. CBCT scans were taken at 0 and at 12-months to assess tertiary dentin formation (volume and grey level intensity), increase in root length, and pathological changes as secondary caries, periapical radiolucency, internal resorption and obliteration of the pulp. The three-dimensional image analysis procedures were performed using ITK-SNAP and 3D Slicer CMF. Comparisons were made using analysis of variance with a fixed effect for treatment and random effects for patient, and patient-by-treatment to account for within-patient correlations. A two-sided 5% significance level was used. There were no significant differences among the three groups regarding tertiary dentin volume (p=0.712) and grey level intensity (p=0.660), increase in root length (p=0.365), prevention of secondary caries (p=0.63) and periapical radiolucency (p=0.80) in the analysed 69 CBCT scans. The study did not find differences among the groups regarding quality and quantity of tertiary dentin formed, increase in root length, absence of secondary caries and other signs of failure as shown by CBCT. Clinical Significance: The results show no significant differences in radiographic outcomes (quality and quantity of tertiary dentin formed, increase in root length, absence of secondary caries and other signs of failure) when using SDF+KI, SDF and RMGIC in IPC. The results of this study can help guide treatment decision making regarding use of SDF and SDF+KI as IPC materials in deep cavitated lesions.
