Achieving an apical seal is critical for apexification treatment of nonvital immature teeth. While this is commonly accomplished using biocompatible mineral trioxide aggregate (MTA), its limitations, such as prolonged setting time, discoloration, and challenging handling, have driven the search for alternative materials. This study aimed to compare the clinical and radiographic success of bioceramic putty Well-Root PT apical plug compared to MTA in the treatment of nonvital immature permanent incisors. Fifty immature nonvital maxillary permanent central incisors in thirty-eight children aged 8–11 years were randomly divided into two groups (25 teeth/group). Group I received MTA apical plugs, and Group II was treated with Well-Root PT apical plugs. Both groups were recalled at 6 and 12 months for clinical and radiographic evaluations. Statistical analysis was done for the gathered data. Both groups showed improved clinical signs and symptoms during all follow-up periods with no statistically significant difference. Regarding the periapical radiolucency (PAR) area, at twelve months, the mean PAR area in the Well-Root PT group was (0.14 ± 0.08) compared to (2.3 ± 0.9) in the MTA group, with highly statistically significant differences (p < 0.001). The mean periapical bone radiodensity in the Well-Root PT group was (178.2 ± 5.4) compared to (164.8 ± 9.4) in the MTA group at twelve-month follow-up, with highly statistically significant differences(p < 0.001). Well-Root PT, with its reduced technical sensitivity, demonstrates satisfactory clinical and radiographic success as an apical plug for nonvital immature permanent incisors compared to MTA.

Leukemic patients often display clinical signs like anemia, thrombocytopenia, and hepatosplenomegaly. Early diagnosis is crucial for intervention and improved prognosis. Dentists can help identify these signs through oral masses, gingival bleeding, and oral ulceration, with radiographical features like bone osteolysis, moth-eating appearance, and abnormal tooth chronology. This study aimed to achieve early diagnosis of leukemic child patients (LCP) by the dentist based on their clinical, age estimation, and radiographical oral signs. Twenty-three children suffer from leukemia, selected after an initial diagnosis based on their clinical signs with an abnormal CBC or abnormal WBCs. These patients were accessed clinically for oral signs and radiographically using panoramic radiographs and cone beam computed tomography (CBCT) to evaluate chronology and bone density. LCP were compared with systematically free control child cases (SFC) who went for a panoramic image and CBCT scan needed for their orthodontic problems. Clinical results for LCP revealed (100%) of cases showed gingival bleeding, (87%) of cases showed gingival masses, (83%) of cases revealed aphthous-like ulceration, and (100%) of cases had different grades of mobility related to the lower first permanent molar used as markers for tooth affection. Radiographical results revealed a statistically significant decrease (P value ≤ 0.05) in LCP age revealed by panoramic and CBCT images in comparison with their actual age. Also, there was a statistically significant decrease in bone density shown by LCP regarding selected regions. LCP could be early diagnosed by the dentist through clinical and radiographical indicators. Diagnosing acute lymphoblastic leukemia (ALL) in its early stages remains a significant challenge due to the nonspecific and often subtle nature of initial symptoms. Dental practitioners can bridge the gap between routine dental care and early systemic disease detection, potentially expediting medical intervention and improving outcomes for children with acute lymphoblastic leukemia.

Introduction The success of primary teeth pulpectomy is strongly reliant on instrumentation techniques and their impact on obturation quality & postoperative pain. Recently, pediatric rotary file systems have been implemented. Aim to compare two pediatric rotary file systems (Kedo-S-Square & Fanta AF™ Baby) with manual K-files concerning obturation quality, instrumentation time, and postoperative pain in root canal preparation of primary molars using cone beam computed tomography (CBCT). Methods A randomized clinical trial was conducted with the trial registration number (TRN: NCT05619796 and date of registration: (17/11/2022) on sixty primary lower 2nd molars in healthy children aged 4–7 years. Molars were assigned randomly to three groups (n = 20). Group-I and -II were prepared with Kedo-S-Square & Fanta AF™Baby rotary systems respectively while group-III was prepared with a manual K-file. Instrumentation time was recorded using a stopwatch. CBCT was used to assess obturation quality immediately & recorded as optimal, underfilled, or overfilled. Postoperative pain was evaluated at 6, 12, 24, 48 h-time intervals using a four-point pain intensity scale. Statistical analysis was performed for the collected data. Results Among the three groups, group-I revealed a greater number of optimally filled teeth (85%) & less instrumentation time (74.75 s) followed by group-II & manual-K file group (p < 0.05). The hand K-file group had significantly more postoperative pain than the two rotary groups (p < 0.05). Conclusion the tested rotary file systems resulted in better obturation quality, less instrumentation time, and less postoperative pain compared to manual-K files during primary teeth pulpectomy. Key points Paediatric rotary files allow for effective root canal preparation and reduced chairside time. CBCT technique’s simplicity with better image quality makes it comfortable for children. Less postoperative pain is associated with less debris extrusion into peri-radicular tissues using pediatric rotary files.

Background Anterior open bite is a challenging condition for pediatric dentists and orthodontists as it causes aesthetic, speech, feeding, and psychological problems; this emphasizes the need for early diagnosis and interception of this malocclusion. Aim This study aimed to evaluate the effects of prefabricated metal-bonded tongue tamers and customized bonded spurs in the early treatment of anterior open bite. Materials and methods A sample of seventy-five children aged 7–9 years were assigned into three groups in which anterior open bite was treated using tongue tamers (group-I), customized composite bonded spurs(group-II), and conventional fixed palatal cribs (group-III). Study model and cephalometric x-ray evaluations were done before and after a three-month follow-up. Data was gathered and statistically analyzed using ANOVA and Bonferroni tests. Results Model overbite at central and lateral incisors was increased in all groups. The highest increase was found in group-I(3.16 ± 1.17, 2.81 ± 0.94)and group-III(3.08 ± 1.10,2.99 ± 1.00) though the difference was not statistically significant. Also, cephalometric overbite was non-significantly increased in all groups with a high increase in group-III(3.13 ± 1.10). Overjet decreased in all groups, with the greatest reduction observed in group-I(-2.58 ± 1.02 and -2.47 ± 0.80 in model and cephalometric respectively) and was significantly different from group-II using pairwise analysis. There was a decrease in SNA and ANB in all groups with more significant improvement in groups-I(-1.20 ± 0.88,-1.65 ± 0.74) and -III(-1.31 ± 0.92, -1.62 ± 0.75) than group-II(-0.63 ± 0.46, -0.90 ± 0.43). Moreover, FMA measurements decreased significantly in group-I (-2.6 ± 1.11). Regarding SNB measurement, there was a non-significant increase in all three groups with the highest increase in group-I(0.49 ± 0.48) followed by group-III(0.34 ± 0.63). The U1/FHP and L1/GoGn angles were non-significantly decreased in all tested groups with the highest decrease in group-I(-1.76 ± 1.00 and-2.54 ± 0.87 respectively). Conclusion Early treatment of anterior open bite, along with tongue tamers' simplicity and aesthetics promoted the malocclusion correction and occlusal function restoration.

To study trends in HIV case notification rates in the Kingdom of Saudi Arabia. A ten year retrospective review of annual HIV case notification returns to the Ministry of Health, Kingdom of Saudi Arabia. Annual Registry statistics covering the period 2000 to 2009 were reviewed. Annual incidence trends were stratified according to the following demographics: age, nationality, geographical region of residence, gender, and mode of disease acquisition. 10,217 new HIV cases (2,956 in Saudi nationals and 7,261 in non-Saudis) were reported. Africans of Sub-Saharan Africa origin accounting for 3,982/7,261 (53%) of non-Saudi cases constituted: Ethiopians (2,271), Nigerians (1,048), and Sudanese nationals (663). The overall average annual incidence was <4 cases per 100,000; 1.5 cases per 100,000 for Saudis (range 0.5-2.5), and 13.2 per 100,000 for non-Saudis (range 5.7-19.0). Notifications increased yearly from 2000 for both groups until a plateau was reached in 2006 at 1,390 new cases. Case notification in Saudi nationals increased from 20% in the early 2001 to 40% in 2009. 4% (124/2,956) of cases were reported in Saudi children. The male to female ratio was 1.6:1 for non-Saudi nationals (43.8% male, 27.3% female) and 4.4:1 for Saudis (23.5% male, 5.4% female). Whilst the numbers of reported HIV cases have stabilised since 2006, HIV/AIDS remains an important public health problem in KSA, both in migrants and Saudi nationals. HIV transmission to Saudi children is also of concern. Optimization of data collection, surveillance, and pro-active screening for HIV is required.

BackgroundScreening of β thalassemia among close relatives is more feasible in highly prevalent countries with limited resources. The purpose of this study is to determine the prevalence of β thalassemia carriers and iron deficiency anemia among relatives of β thalassemia patients in Mid Delta, Egypt.MethodsThis is a cross-sectional multi-center study conducted on 2118 relatives of patients with β thalassemia from different Egyptian governorates in the Mid Delta region. They were subjected to history taking with precise determination of geographic location, general examination, and the following investigations: complete blood counts, serum ferritin for those who showed microcytic hypochromic anemia, and high-performance liquid chromatography for those who were not diagnosed as iron deficiency anemia.ResultsThe total prevalence of iron deficiency anemia among close relatives of confirmed β thalassemia patients in the Nile Delta region was 17.19%. The highest prevalence of iron deficiency anemia (45.05%) was reported in Al-Gharbia Governorate, followed by Al-Menoufia Governorate (21.67%), and the lowest prevalence was that of Al-Sharkia Governorate (4.91%). The differences were highly statistically significant (p < 0.001). β thalassemia carrier prevalence rate in the studied relatives was 35.84%, with the highest prevalence detected in Al-Sharkia Governorate (51.32%), followed by Kafr-Alsheikh and Al-Dakahilia Governorates (41.78%, 37.13%) respectively, while Al-Menoufia Governorate had the lowest prevalence rate (25.00%). These differences were also highly statistically significant (p < 0.001).ConclusionMore than one-third of relatives of patients with β thalassemia are carriers of the disease, while 17.19% suffer from iron deficiency anemia. This study demonstrates the importance of tracing the high number of beta thalassemia carriers among relatives of patients with β thalassemia in Egypt.

Abstract BackgroundCameriere’s original formula based on open apex measurements is a reliable, clinically applicable method for dental age estimation in different populations children. Dental development may differ between Egyptian children and other ethnic populations which may affect dental age accuracy using Cameriere’s formula.AimFirstly, to verify Cameriere’s original formula on large Egyptian children sample, secondly, to develop an Egyptian-specific formula based on Cameriere’s method.Material and methodsA prospective cross-sectional study of 762 good quality Orthopantomograms (OPGs) of 5–15 aged healthy Egyptian children selected from Nile Delta governorates between August 2020 and December 2021. Chronological age (CA) was calculated by subtracting birth date from radiograph date. OPGs were analyzed for N0, S, Xi morphologic variables using Sidexis program after that dental age was calculated using Cameriere’s formula then compared to CA. Multiple linear regression model was used to adapt Cameriere’s formula to construct an Egyptian formula. The same sample was used to verify the new formula accuracy.ResultsA total of 1093 OPGs were collected; 762 OPGs which met inclusion criteria were analyzed. Cameriere’s original formula revealed − 0.59- and − 0.53-year underestimation of females and males dental age (DA) respectively (p < 0.001). Regression analysis using the morphologic variables showed that X4, X7, N0 contributed significantly to CA yielding Egyptian-specific formula. New formula showed − 0.12-year male underestimation and 0.1-year female overestimation (p > 0.05).ConclusionEgyptian formula was more accurate than Cameriere’s formula in Egyptian children.Clinical relevanceEgyptian-specific formula decreases the gap between CA and DA, so a relative approximate age is obtained that helps proper diagnosis and treatment planning for orthodontic and pediatric dentistry problems.

Background Pediatric rotary file systems were developed to solve manual file limitations. With many systems available, it may be tricky to select the most appropriate one. Aim to assess & compare Kedo-S Square, Fanta-AF™-Baby rotary files with manual K-file concerning removed dentin amount, canal transportation, centric ability & root canal taper using CBCT in primary anterior teeth. Design Extracted Seventy-five upper primary anterior teeth with intact 2/3 root length were collected and divided into three groups based on root canal instrumentation, group-I: prepared using K-file, group-II: prepared using Kedo-S Square, and group-III: prepared using Fanta AF™ Baby file. The teeth were imaged with CBCT before & following canal instrumentation. Then, the removed dentin amount was calculated at each root-canal level. The Kruskal-Wallis test was utilized to statistically analyze study data. Result The difference among the three groups was highly statistically significant at cervical & apical thirds concerning dentin thickness changes on both mesial & distal sides following canal preparation with the least removed dentin in the Kedo-S Square group( P  < 0.0001). Regarding transportation & centering ability, a non-significant difference between the three groups was found. 80% of the Fanta AF™ Baby group had good-tapered preparation compared to the Kedo-S Square (72%) and K-file (40%) groups( P  < 0.05). Conclusion Kedo-S Square was preferable to Fanta-AF TM -Baby & manual K-files in primary root canal preparation.

Resident physicians are the first-line health service providers, subjected to prolonged working hours, sleep deprivation and high job demands. Work stress causes reduction in productivity, suboptimal patient care and medical errors. To determine the level of stress among residents and associated factors and stressors. A cross-sectional study at Tanta University Hospitals recruited residents ( n  = 278), between December 2016 and February 2017. Job stress was assessed using a predesigned questionnaire. The mean age was 26.53 ± 1.35, and 46.4% were males. The majority reported they work more than 48 h/week, do not get a break during work and have a night shift periodically (87%, 83.1% and 94.2%, respectively). Only 4 (1.4%) had low stress while 169 (60.8%) had moderate and 105 (37.8%) had high stress. The study revealed a statistically significant association between high level of stress and being a single resident ( p  = 0.017), belonging to surgical departments ( p  = 0.001) and an absence of break during working hours ( p  = 0.001). The prime sources of stress were underpayment for the job (87.4%), serving to large number of patients (85.2%), disruption of home life due to long hours at work (83.9%), conflict of responsibilities (81.3) and complying with increasing bureaucratic procedures (78.8%) besides no available fund for research (74.8%). Medical residents experienced moderate to high level of job stress. Thus, there is a need for stress management programs during residency training period taking in consideration main sources of stress.

ObjectivesThe complex root canal anatomy of primary teeth keeps it very tricky to attain appropriate cleansing by biomechanical instrumentation, so obtaining an obturating material with excellent antimicrobial properties is a challenge in current clinical pulpectomy practice. So, this study aimed to assess the clinical and radiographic performance of zinc oxide-ozonated olive oil as a primary root canal filling material.Materials and methodsNinety non-vital primary molars in children ranging from 4 to 8 years were allocated into three groups in which root canals were filled with zinc oxide-ozonated olive oil, zinc oxide-olive oil, and zinc oxide-eugenol (ZOE) according to each group after pulpectomy procedure. Clinical and radiographic evaluations were done at 3-, 6-, and 12-month follow-up periods. Statistical analysis was performed for the collected data.ResultsAll study groups showed a significant improvement regarding clinical signs and symptoms during follow-up periods. Ozonated-olive oil group revealed a significant increase in furcation radiodensity and a decrease in periodontal ligament space at 3-, 6-, and 12-month follow-up intervals compared to other groups.ConclusionZinc oxide-ozonated olive oil and zinc oxide-olive oil paste had shown good clinical and radiographic success for primary teeth pulpectomy.Clinical relevanceThe intricate torturous primary root canal anatomy, in addition to the child’s negative behavior, interferes with the complete debridement, so the long-lasting antibacterial effect of the primary root canal filling material aids in the pulpectomy success.
