    Abstract Objectives: Effective disinfection of the root canals is the cornerstone of successful endodontic treatment. Diminishing the microbial load within the root canal system is crucial for healing in endodontically treated teeth. The aim of this study was to evaluate the effect of 2780 nm Er,Cr:YSGG and 940 nm diode lasers on the eradication of microorganisms from single-rooted teeth with asymptomatic apical periodontitis.
    Materials and methods: Thirty participants conforming to the inclusion criteria were randomly divided into 3 groups according to the disinfection protocol used; Conventional group: 2.5% Sodium Hypochlorite (NaOCl) and 17% EDTA solution NaOCl/EDTA, Dual laser group: 2780 nm Erbium, chromium: yttrium scandium-gallium-garnet (Er,Cr:YSGG) laser and 940 nm diode laser Er,CrYSGG/Diode, and Combined group: 17% EDTA and 940 nm diode laser EDTA/Diode. Bacterial samples were collected before and after intervention. The collected data were statistically analyzed using Friedman's test and Kruskal-Wallis test (P ≤ 0.05).
    Results: The results of the study showed that both dual laser Er,CrYSGG/Diode and combined laser EDTA/Diode groups showed significantly less mean Log10 CFU/ml of aerobic and anaerobic bacterial counts than the conventional NaOCl/EDTA group.
    Conclusions: In this study we evaluated in vivo the bactericidal efficacy of three disinfection protocols for endodontic treatment of single-rooted teeth with apical periodontitis. The results indicated that both dual laser Er,CrYSGG/Diode and combined laser EDTA/Diode groups provide superior bactericidal effect compared to the conventional NaOCl/EDTA group.
    Clinical relevance: The integration of lasers into root canal disinfection protocols has demonstrated significant bacterial reduction which might promote healing and long-term success.

    Abstract Objectives: To predict temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDWR) from condylar shape, position, and dimensions obtained from CBCT images.
    Methods: This cross-sectional study was performed on 17 patients suffering from temporomandibular disorders diagnosed by history taking according to the chart of the American Association of orthodontists, clinical examination according to the Helkimo index and MRI. CBCT and MRI examinations were performed within one-week interval. Disc position, diagnosed by MRI was used as the gold standard. TMJs with posterior disc displacement or anterior disc displacement without reduction were excluded. Qualitative and quantitative analyses were performed on CBCT images to find the correlation between condylar variables and ADDWR. A logistic regression model was created to estimate ADDWR from condylar dimensions (height, width and depth).
    Results: Condylar shape and condylar position in the glenoid fossa were significantly correlated with ADDWR (P < 0.05). Condylar width, height and depth were significantly smaller in condyles with ADDWR compared to condylar dimensions in normal disc position. Logistic regression analysis could be used to predict the probability of anterior disc displacement with reduction from condylar dimensions.
    Conclusion: Condylar shape, position, and dimensions assessed by CBCT are significantly correlated with ADDWR of the TMJ. Substituting the values of condylar width, height and depth in the equation suggests the probability of ADDWR.

    Abstract Objectives: To evaluate the effects of different types of restorations on observer ability to detect proximal caries in CBCT images.
    Materials and methods: Forty human premolars and molars with artificial proximal caries were placed proximal and distal to 5 molars having different restorations (amalgam, composite, resin-modified glass ionomer cement (RMGIC) fillings, zirconia, and lithium disilicate crowns) and a non-restored molar. CBCT scans were obtained using i-CAT
    Results: Caries detection in teeth surfaces mesial and distal to amalgam showed compromised specificity and accuracy. Moreover, caries detection in teeth surfaces mesial to zirconia crown showed low sensitivity, specificity, and accuracy. Capability of CBCT in detection of proximal caries in teeth adjacent to composite, RMGIC, and lithium disilicate was comparable to those adjacent to non-restored molar.
    Conclusions: CBCT scans performed for tasks other than caries detection should be assessed for proximal caries in absence of any restorations as well as in presence of composite, RMGIC fillings, and lithium disilicate crowns. However, CBCT should not be used for proximal caries detection in teeth adjacent to amalgam and teeth surfaces mesial to zirconia crowns.
    Clinical significance: It is important to investigate the influence of artifacts produced by various restorations on CBCT-based caries detection to optimize CBCT benefits, caries diagnosis and avoid unnecessary treatment of sound surfaces.

    Abstract Objectives: This study was undertaken as an attempt to assess radiographic temporomandibular joint (TMJ) changes in relation to rheumatoid factor (RF), anticitrullinated protein (ACCP) antibodies and disease activity score 28 (DAS28) in rheumatoid arthritis (RA) patients to find the best predictor of rheumatoid affection of the TMJ with the ultimate goal of maintaining TMJ function and preventing joint damage.
    Methods: 20 Rheumatoid Arthritis patients as well as 20 volunteers were included in this study. RA group were assessed for RF, ACCP, DAS28. Both groups were assessed by CBCT for TMJ dimensions and radiographic osteoarthritic changes. All data were statistically analyzed.
    Results: Rheumatoid Arthritis group showed significantly less condylar height and more radiographic osteoarthritic changes than the control group. RF showed no significant correlation with either TMJ measurements or TMJ radiographic osteoarthritic changes. ACCP showed significant inverse correlation with condylar height and anteroposterior (AP) dimensions, but non-significant relation with mediolateral dimension and radiographic osteoarthritic changes. DAS28 showed significant inverse correlation with condylar AP and mediolateral dimensions. It also showed significant correlation with flattening of the TMJ condylar head and flattening of the articular fossa. Patients with high and moderate disease activity showed significantly smaller AP TMJ dimension than patients with low disease activity. Disease activity showed statistically significant direct correlation with all osteoarthritic changes except for erosions of the glenoid fossa and condyle.
    Conclusion: Disease Activity Score28 score and disease activity are strong indicators of TMJ affection in RA patients when compared to RF and ACCP. ACCP is a better indicator of changes in condylar measurements than TMJ osteoarthritic changes. While RF is the least efficient indicator of TMJ involvement in RA patients.

    Abstract Objective: The objective of this study was to assess the volume, area, and dimensions of the oropharyngeal airway (OPA) in a previously repaired nonsyndromic unilateral cleft lip and palate (UCLP) versus bilateral cleft lip and palate (BCLP) patients when compared with noncleft controls using cone beam computed tomography (CBCT).
    Design: This was a retrospective case-control study.
    Setting: The Cleft Care Center and outpatient clinic that are affiliated to our faculty were the settings for the study.
    Participants: A total of 58 CBCT scans were selected of preadolescent individuals: 14 BCLP, 20 UCLP, and 24 age- and gender-matched noncleft controls.
    Variables: Variables were volume, cross-sectional area (CSA), midsagittal area (MSA), and dimensions of OPA.
    Statistical analysis: One-way analysis of variance and post hoc tests were used to compare variables. Statistical significance was set at P ≤ .05.
    Results: UCLP showed significantly smaller superior oropharyngeal airway volume than both controls and BCLP ( P ≤ .05). BCLP showed significantly larger CSA at soft palate plane and significantly larger MSA than both UCLP and controls ( P < .05).
    Conclusions: UCLP patients at the studied age and stage of previously repaired clefts have significantly less superior oropharyngeal airway volume than both controls and BCLP patients. This confirms that preadolescents with UCLP are at greater risk for superior oropharyngeal airway obstruction when compared with those BCLP and controls. Furthermore, BCLP patients showed significantly larger CSA at soft palate plane and MSA than both controls and UCLP patients. These variations in OPA characteristics of cleft patients can influence function in terms of respiration and vocalization.

    Abstract Introduction: We aimed to compare the diagnostic accuracy of 5 cone-beam computed tomographic (CBCT) systems in detecting vertical root fractures (VRFs) and to assess whether fracture identification is affected by the presence of root canal filling.
    Methods: Eighty extracted posterior teeth were included in this study. They were grouped according to the presence/absence of VRFs and the presence/absence of endodontic treatment. The teeth were then inserted in 5 dry skull/mandible assemblies. CBCT scans were performed using 5 different commercially available systems. Two observers evaluated the resultant multiplanar images twice for VRFs using a 3-point scale.
    Results: i-CAT (Imaging Sciences International, Hatfield, PA) showed the highest diagnostic accuracy in the detection of VRFs among the 5 investigated CBCT systems. The presence of root canal filling did not significantly decrease the ability to detect VRFs by all the studied systems. In the detection of VRFs in endodontically treated teeth, i-CAT was the most accurate, whereas 3D Accuitomo (J. Morita, Kyoto, Japan) was the least. Interobserver agreement was moderate for the i-CAT and fair for the rest of the studied modalities, whereas intraobserver agreement was good for the Scanora 3D (Soredex, Tuusula, Finland) and moderate for images from the other CBCT machines.
    Conclusions: At the specified exposure parameters in the detection of VRFs in non-root canal-filled teeth, i-CAT showed the highest diagnostic accuracy followed by Planmeca Promax 3D (Planmeca, Helsinki, Finland), Scanora 3D, Accuitomo 3D, and Galileos 3D (Sirona Dental Systems, Bensheim, Germany), respectively. In the detection of VRFs in root canal-filled teeth, i-CAT showed the highest diagnostic accuracy followed by Planmeca Promax 3D, Scanora 3D, Galileos Comfort (Sirona Dental Systems), and Accuitomo 3D.

    Abstract Objective: To assess the nasopharyngeal airway volume, cross-sectional area, and depth in previously repaired nonsyndromic unilateral cleft lip and palate versus bilateral cleft lip and palate patients compared with noncleft controls using cone-beam computed tomography with the ultimate goal of finding whether cleft lip and palate patients are more liable to nasopharyngeal airway obstruction.
    Design: A retrospective analysis comparing bilateral cleft lip and palate, unilateral cleft lip and palate, and control subjects. Significance at P ≤ .05.
    Setting: Cleft Care Center and the outpatient clinic that are both affiliated with our faculty.
    Participants: Cone-beam computed tomography data were selected of 58 individuals aged 9 to 12 years: 14 with bilateral cleft lip and palate and 20 with unilateral cleft lip and palate as well as 24 age- and gender-matched noncleft controls.
    Variables: Volume, depth, and cross-sectional area of nasopharyngeal airway were measured.
    Results: Patients with bilateral cleft lip and palate showed significantly larger nasopharyngeal airway volume than controls and patients with unilateral cleft lip and palate (P < .001). Patients with bilateral cleft lip and palate showed significantly larger cross-sectional area than those with unilateral cleft lip and palate (P < .001) and insignificant cross-sectional area compared with controls (P > .05). Patients with bilateral cleft lip and palate showed significantly larger depth than controls and those with unilateral cleft lip and palate (P < .001). Patients with unilateral cleft lip and palate showed insignificant nasopharyngeal airway volume, cross-sectional area, and depth compared with controls (P > .05).
    Conclusions: Unilateral and bilateral cleft lip and palate patients did not show significantly less volume, cross-sectional area, or depth of nasopharyngeal airway than controls. From the results of this study we conclude that unilateral and bilateral cleft lip and palate patients at the studied age and stage of repaired clefts are not more prone to nasopharyngeal airway obstruction than controls.

    Abstract Objective: To compare the diagnostic accuracy of digital intraoral and extraoral bitewing (EO BW) radiography in the detection of enamel proximal caries regardless of their ability to separate contacts.
    Methods: Artificial caries with different degrees of decalcification was induced in 80 human sound premolars and molars using formic acid. Intraoral radiographs were taken with photostimulable phosphor plate (PSP) and complementary metal oxide semiconductor (CMOS), using the paralleling bitewing technique. Extraoral bitewing radiographs were obtained using Sirona digital panoramic X-ray unit (Sirona Siemens, Bensheim, Germany). In total, 160 proximal surfaces were assessed by 2 observers twice. Area under the receiver operating characteristic curve (Az) values for each image type, observer and reading were compared using z-tests, with a significance level of p ≤ 0.05. Sensitivity, specificity, positive-predictive value and negative-predictive value for each observer and reading were calculated.
    Results: Spearman's test showed a strong positive correlation between the duration of demineralization and histological grading of carious teeth surfaces. For the three radiographic techniques, intraobserver reliability was strong to excellent. Moreover, interobserver agreement was strong. The differences between all detection methods were not statistically significant (p > 0.05). Intraoral bitewing using CMOS sensor had the highest sensitivity while EO BW had the highest specificity in the detection of incipient proximal caries.
    Conclusions: Within the limits of the ex vivo design, the difference in diagnostic accuracy between the three radiographic techniques was not significant. EO BW could be used in the detection of enamel proximal caries with results comparable with intraoral bitewing with PSP plate and CMOS sensor.
