Abstract
The present meta-analysis aimed to describe the methods to determine the working length in primary teeth pulpectomy, also evaluating and comparing their reliability. A systematic review was performed following the PRISMA Statement. The electronic search was conducted on PubMed, Scopus, Cochrane Library and Web of Science. After the screening protocol, a number of 14 studies were included in the qualitative analysis, while seven were included in the quantitative one. The mean working length determined by the electronic apex locator was 11.8 mm (9.0-15.55), while 12.42 mm (11.0-13.52) and 12.3 mm (9.73-15.93) were the mean working length observed with the conventional radiography and the digital radiography, respectively. No statistically significant difference was detected in quantitative analysis between the investigated methods. The present meta-analysis showed that electronic apex locator, conventional radiography and digital radiography are similar in determining working length in primary teeth.

Abstract
Objectives:
To compare the effectiveness of Silver nanoparticles (AgNPs) and Chlorhexidine (CHX) mouthwash on Streptococcus mutans (S. mutans), Lactobacillus spp., and Candida albicans (C. albicans) counts O’Leary plaque index (O’Leary PI) scores, and salivary pH levels among children.
Materials and Methods:
The study sample consisted of 117 eligible participants aged 12–18 years. They were divided into control, CHX, and AgNPs groups, with 39 subjects per group. The log10 salivary microbial counts, O’Leary PI, and salivary pH values were recorded and statistically analyzed at baseline and the 28th day. Descriptive statistics were presented as the mean ± standard deviation. In addition, the analyses of variance (ANOVA) and Tukey posthoc test were implemented. The p-value ≤ 0.05 denotes a significant difference between the two points.
Results:
AgNPs and CHX mouthwash were found to have significantly reduced salivary microbial counts and O’Leary PI scores. The salivary pH levels notably increased on the 28th day (p-value < 0.001). All measured outcomes demonstrated notable effects, with the greatest observed for the CHX group, followed by the AgNPs group, and finally, the control group.
Conclusion:
Chlorhexidine and AgNPs mouthwash effectively reduced the cariogenic microbial count and dental plaque and improved the salivary pH values. AgNPs mouthwash may be used as an adjunctive measure to prevent dental caries.

Abstract
BACKGROUND Working length is an important step in primary teeth pulpectomy. AIM To evaluate whether there is a significant difference in the accuracy of electronic apex locators compared to the conventional radiography in working length measurements. DESIGN Sixty-four children (192 canals) between 5 and 9 years of age with indication for pulpectomy of a primary molar were included after eligibility criteria. A radiographic measurement was obtained from pre-operative radiography from the cusp tip to the apex or resorption of the root. The electronic measurement was obtained from a complete measurement of the canal with an electronic device up to the apex. Data were analysed with Bland-Altman plots and Wilcoxon test. Statistical significance was set at P ≤ .05. RESULTS Statistically, there is not any significant difference between radiographic and electronic measurements for the palatal canal or distal canal, as well as mesiobuccal canals (P > .05). Statistically, there, however, is a significant difference between the measurements for the distobuccal canal and mesiolingual canal measurements (P < .05). High internal consistency for both radiographic and electronic methods was achieved (α ≅ 1). CONCLUSIONS Electronic and radiographic methods are similar in determining the length measurement of the root canals in primary teeth pulpectomies, except in distobuccal or mesiolingual canals.

Abstract
Aims The purpose of this study was to evaluate the accuracy of a new-generation electronic apex locator (iPex) to determine working length in primary teeth with or without root resorption as compared with the conventional radiographic method. Materials and methods A sample of 30 primary posterior teeth which are indicated for pulpectomy were selected for the study. After obtaining the informed consent from the parents, local anesthesia was administered. Access cavity was prepared with no.10 round bur. Initial exploration of the canals was done with no.10 K-file. Pulp was extirpated with a barbed broach followed by thorough irrigation of the canals with 0.9% saline. Initially, working length was obtained with iPex (new-generation by Nakanishi International) apex locator using no.10 K-file, which was then compared with conventional radiographic method (Ingle’s method). Results A total of 65 canals were available for the measurement. The data were analyzed using Statistical Analysis system and t-tests were carried out. There was no statistically significant difference found when using iPex apex locator for working length determination as compared with that of conventional radiographic method (p = 0.511). Conclusion Working length determined by iPex apex locator is comparable with that of conventional radiographic method, hence, can be used as an alternative in determining the working length of primary teeth.

Abstract
BACKGROUND Severe early childhood caries (s-ECC), which has quite high prevalence among children, is a widespread problem with significant impacts among both developing and developed countries. At present, it is widely known that no early detective techniques and diagnostic tests could have high sensitivity and specificity when using for clinical screening of s-ECC. In this study, we had applied magnetic bead (MB)-based matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to screen distinctive candidate biomarkers of this disease, so as to establish protein profiles and diagnostic models of s-ECC. METHODS Firstly, we used the technique mentioned above to detect specifically expressed peptides in saliva samples from ten children with s-ECC, separately at the time point of before, 1 and 4 weeks after dental treatment. Then a diagnostic model for s-ECC was established with the K nearest-neighbour method, which was validated in another six children in the next stage of study. After that, linear ion trap-orbitrap-mass spectrometry (LTQ-Orbitrap-MS) was performed to identify which of the proteins in saliva might be the origination of these peptides. RESULTS We found that seven peptide peaks were significantly different when comparing the three time points, among them two were higher, while other five were lower in the pre-treatment s-ECC group compared with post-treatment. The sensitivity and specificity of the diagnostic model we built were both 83.3 %. Two of these peptides were identified to be segments of histatin-1, which was one important secretory protein in saliva. CONCLUSIONS Hereby we confirmed that MB-based MALDI-TOF MS is an effective method for screening distinctive peptides from the saliva of junior patients with s-ECC, and histatin-1 may probably be one important candidate biomarker of this common dental disease. These findings might have bright prospect in future in establishing new diagnostic methods for s-ECC.

Abstract
AIM The aim of this in vivo study was to evaluate the accuracy and reliability of electronic apex locater and radiographic determination of root canal length in primary teeth. METHODOLOGY A total of 32 human primary molar teeth (96 roots) were selected. After endodontic access preparation, root canals were irrigated with physiological saline solution. The access cavities were dried with cotton pellets and, the roots were dried with paper points before performing the electronic measurement. The root canal length measurements were first taken with an apex locater (EndoMaster), and then, a size ♯ 15 K-file was inserted into the root canal, and radiography was taken to determine the working length measurements. The measurement data were recorded and compared by one-way anova and Kruskal-Wallis tests. P < 0.05 was accepted for the significance. RESULTS The mean values for radiography were 13.23 ± 1.92 mm and for EndoMaster were 13.08 ± 1.77 mm. The accuracy of EndoMaster was 80.2% in correct measurements ±1 mm (P < 0.001). CONCLUSION The electronic apex locators could be useful in determining working length and thereby decreasing the need for radiographs and exposure to ionizing radiation in pediatric dental patients.
