The global population ageing, and the pace of ageing is accelerating. Although people are living longer, these additional years are not being gained in health, and disability, chronic and long-term conditions increase with age. In response to the challenges of an ageing population, the United Nations and World Health Organisation declared 2021-2030 the Decade of Healthy Ageing, with the purpose of collaborative action to foster longer and healthier lives. This review explores the WHO public health framework for healthy ageing and global trends and policies, using the UK as an example of policy implementation. In response to the urgent need to consider the impact of ageing on oral health and oral healthcare systems, an integrated model for healthy ageing and oral health is proposed.

Purpose: Practicing oral habits beyond the normal age range is assumed to be due to underlying psychological disturbance and could result in a deformation of the orofacial structure. The first step in managing such a health condition is to evaluate its size. Thus, this study aimed primarily to assess the prevalence of oral habits among a group of school children aged from 5 to 7 years, in Cairo, Egypt. The secondary aim of the study was to investigate some possible related predictors along with the mother's perception of the child's oral health-related quality of life.
Methods: A Google form questionnaire was designed, utilizing the third domain of Nordic Orofacial Test-Screen (NOT-S), to assess the presence or absence of oral habits and their types, if reported. Also, there were two global rating items to test the child's oral health-related quality of life from the mother's prospection, along with one item to inquire if the mother thinks that the oral habits are harmful to the child. A total number of 23 schools in Cairo, Egypt were randomly selected, and the link to the Google form was distributed through the parent's groups on social media. All high-quality complete responses were analyzed using the SPSS program, and a Log-binomial regression model was constructed, to determine the significant predictors of practicing oral habits in children.
Results: Among the analyzed 1128 responses, the total number of answers to the third domain of interview part of NOT-S was 1235, with a response rate of (60.39%), no habits were reported in 635 children (51.4%), while nail biting was noted in 21.8%, bruxism in 17.9% and Sucking habits in 8.9%. In total, 63.8% of children who were reported by their parents to be the "only child" didn't practice any habit, and a higher prevalence of oral habits was detected in children with siblings. There was no detectable association between the mother's educational level and practicing any of the habits, although there was an association between the mother's educational level and their awareness of the harmful effect of oral habits on the child. The mothers' answers to the global rating items were not associated with any of the oral habits.
Conclusion: The most prevalent oral habit in the current study was the nail-biting habit. The presence of other siblings and the number of siblings were contributory factors in the occurrence of oral habits, while mothers' educational level was not associated with practicing oral habits. The mothers' awareness of the harmful effect of oral habits on the children was not satisfactory, and there was no association between oral health-related quality of life and the children's oral habits, from the mothers' perspective.

Background: The detection and early diagnosis of root fractures can be challenging; this difficulty applies particularly to newly qualified dentists. Aside from clinical examination, diagnosis often requires radiographic assessment. Nonetheless, human fallibility can introduce errors due to a lack of experience.
Aim: The proposed system aimed to assist in detecting root fractures through the integration of artificial intelligence techniques into the diagnosis process as a step for automating dental diagnosis and decision-making processes.
Materials and method: A total of 400 radiographic images of fractured and unfractured teeth were obtained for the present research. Data handling techniques were implemented to balance the distribution of the samples. The AI-based system used the voting technique for five different pretrained models namely, VGG16, VGG19, ResNet50. DenseNet121, and DenseNet169 to perform the analysis. The parameters used for the analysis of the models are loss and accuracy curves.
Results: VGG16 exhibited notable success with low training and validation losses (0.09% and 0.18%, respectively), high specificity, sensitivity, and positive predictive value (PPV). VGG19 showed potential overfitting concerns, while ResNet50 displayed progress in minimizing loss but exhibited bias toward unfractured cases. DenseNet121 effectively addressed overfitting and noise issues, achieving balanced metrics and impressive PPVs for both fractured and unfractured cases (0.933 and 0.898 respectively). With increased depth, DenseNet169 demonstrated enhanced generalization capability.
Conclusion: The proposed AI- based system demonstrated high precision and sensitivity for detecting root fractures in endodontically treated teeth by utilizing the voting method.

Introduction: Treatment of an immature permanent tooth required a special disinfection protocol due to the presence of thin radicular walls, which are prone to fracture. Mineral Trioxide Aggregate (MTA) has been proposed as a root repair material for root canal treatment. The aim of this in vitro study was to compare the push-out bond strength of conventional White MTA cements and second generation NeoMTA 2 in imitated immature roots treated with different disinfection protocols, which are 5.25% sodium hypochlorite (NaOCl), followed by 17% ethylenediaminetetraacetic acid (EDTA), and NaOCl, followed by 20% etidronic acid (HEBP).
Methods: The root canals of freshly extracted single-root teeth were manually prepared until 90 K-file to imitate immature roots. Roots were randomly divided into four groups (G) according to the disinfection protocol (n = 15 per group). where G1 (NaOCl + EDTA + White MTA) and G2 (NaOCl + EDTA + NeoMTA 2) While G3 (NaOCl + HEBP + White MTA) and G4 (NaOCl + HEBP + NeoMTA 2) All groups were activated with manual agitation. All specimens were incubated for 48 h. The apical third of each root was perpendicularly sectioned to attain a slice of 3 mm thickness. Push-out bond strength values were assessed using a two-way ANOVA and a Student's t test.
Results: G3 and G4 that were treated with HEPB showed higher significant push-out bond strength mean values than G1 and G2 treated with an EDTA chelating agent. Irrespective of the chelating agent used, it was found that both NeoMTA 2 and White MTA had no significant influence on push-out bond strength mean values (p ≤ 0.05).
Conclusion: The combined use of 5.25% NaOCl and 20% HEBP increased the push-out strength values of both NeoMTA 2 and White MTA, rendering them suitable to be used as an alternative chelating agent to EDTA.

Background
Managing dental caries in primary teeth with pulp involvement is a significant challenge. Clinical guidelines offer recommendations for effective management.
Aim
To identify and analyze policies, guidelines, and recommendations for treating primary teeth with pulp-involved carious lesions, highlighting existing research gaps and setting the foundation for future research.
Methods
A comprehensive search was conducted across databases (PubMed, Scopus, Embase, GIN, and LILACS) and grey literature sources (Trip and ProQuest) to identify guidelines, consensus, policy, and position statements on primary teeth pulp therapy and extraction thresholds. Two independent reviewers screened the abstracts and titles, followed by full-text screening.
Results
After removing duplication, of the 1098 records, 14 were selected for analysis. This review examined various treatments for deep caries lesions in primary teeth, including indirect/direct pulp capping, pulpotomy, pulpectomy, lesion sterilization/tissue restoration, and extraction. Time search was restricted to documents published from 30th January 2008 to 30th January 2024, offering insights into evolving clinical practices.
Conclusion
Treatment for carious lesions in primary teeth involving the pulp depends on clinical indications and may involve minimally invasive techniques. Recommended options are indirect pulp capping, pulpotomy, and pulpectomy, while direct capping and tooth removal are discouraged. Further research is needed to address gaps, improve guideline development, and enhance consistency of recommendations.

Objective
This study aims to assess the efficacy of bioceramic (BC) sealer when applied using the single cone technique (SCT), in comparison to AH Plus sealer applied with the cold lateral condensation technique (LCT), concerning their impact on the healing of large-sized periapical lesions in both untreated and retreatment cases.
Materials and methods
A randomized controlled trial was conducted on 41 patients who had 60 permanent teeth in the maxillary incisors that were accompanied by large-sized periapical lesions. The included teeth were radiographed with cone beam computed tomography (CBCT) images and divided equally into two groups according to the endodontic treatment statute (30 untreated previous cases and 30 retreated cases). Subsequently, teeth received uniform preparation, irrigation, and dressing procedures. Then each group was divided equally according to the used sealer (15 teeth obturated using AH plus sealer with LCT and 15 teeth obturated using BC sealer with SCT). All cases were followed up after 6 and 12 months with CBCT images. Subsequently, the change in periapical lesion diameter (PLD) was observed as an indicator to determine the treatment outcome score. One-way ANOVA and Mann–Whitney U test were used to analyze the PLD changing and scoring the treatment outcome during the follow-up periods. The significance level was set at α = 0.05.
Results
There were no statistically significant differences between untreated and retreatment cases neither using AH plus sealer with LCT nor BC sealer with SCT regarding changes in PLD in the follow-up periods. Moreover, there were no significant differences between groups regarding treatment outcome scores in the follow-up periods. All groups showed a high success rate.
Conclusions
Successful treatment was achieved for untreated or retreatment maxillary incisor cases accompanied by large-sized periapical lesions using either BC sealer with the SCT or AH Plus sealer with LCT with a similar high success rate up to 12 months follow-up period.
本研究旨在评估生物陶瓷(BC)封闭剂在使用单锥技术(SCT)时与使用冷侧凝技术(LCT)的 AH Plus 封闭剂相比,对未经治疗和再治疗病例中大尺寸根尖周病变愈合的影响。这些患者的牙齿都经过了锥形束计算机断层扫描(CBCT)影像检查,并根据牙髓治疗章程平均分为两组(30 个以前未治疗过的病例和 30 个修复过的病例)。随后,牙齿接受统一的预备、冲洗和包扎程序。然后,根据封闭剂的使用情况将每组牙齿平均分成两组(15 颗牙齿使用 AH 加封闭剂和 LCT 封闭,15 颗牙齿使用 BC 封闭剂和 SCT 封闭)。所有病例均在 6 个月和 12 个月后接受 CBCT 图像随访。随后,观察根尖周病变直径(PLD)的变化,作为确定治疗效果评分的指标。采用单因素方差分析和曼-惠特尼 U 检验分析随访期间 PLD 的变化和治疗效果评分。结果未治疗病例和再治疗病例在随访期间的 PLD 变化方面,无论是使用 AH 加 LCT 封闭剂还是 BC 封闭剂加 SCT,均无显著统计学差异。此外,各组在随访期间的治疗效果评分方面也无明显差异。结论对于未经治疗或再治疗的上颌切牙病例,如果伴有大面积根尖周病变,无论是使用萃取封闭剂加SCT,还是使用AH加封闭剂加LCT,都能获得成功的治疗,而且在12个月的随访期内,成功率同样很高。

Background
This study aimed to evaluate the efficiency of diode LASER activated irrigation in the removal of GuttaFlow Bioseal root canal filling material during retreatment.
Materials and subjects
Root canals of forty-five single-rooted human mandibular premolar teeth were prepared with ProTaper Universal rotary system and obturated with lateral condensation obturation technique using Gutta Percha and Roeko GuttaFlow Bioseal root canal sealer. All specimens were retreated with ProTaper Universal Retreatment System files then divided to three different groups according to the technique of activation of irrigation. Samples were sectioned, and the residual filling remnants were captured using digital camera attached to microscope. Data was collected by three different interpreters, to eliminate the subjectivity of the process, using the ImageJ Software. The mean value of the data was obtained and evaluated statistically. The significance level was set at P ≤ 0.05.
Results
The remaining filling materials in the canals irrigated with ultrasonic activation (6.17 ± 1.42 at coronal level, 10.93 ± 1.91at middle level, and 14.58 ± 2.23 at apical level) were less than these irrigated with LASER activation (15.87 ± 3.78 at coronal level, 21.28 ± 4.44 at middle level, and 27.06 ± 2.68 at apical level). Maximum amount of remaining filling materials was present in the canals irrigated with passive side-vented syringe (23.07 ± 3.22 at coronal level, 38.09 ± 7.27 at middle level, and 34.24 ± 9.77 at apical level).

Background: Pakistan faces a significant burden of oral diseases, which can be effectively reduced through preventive measures. Dentistry in Pakistan predominantly focuses on corrective dental procedures, increasing the treatment costs and widens disparities in oral healthcare access. To address this gap and meet the country's oral health needs, Aga Khan University initiated a Dental Hygiene program aimed to expand and diversify the oral health workforce and improving access to quality care in various healthcare settings. Due to limited awareness of this profession in the country, the program encounters significant challenges.
Aim: This article aims to present a SWOT analysis of the Dental Hygiene profession in Pakistan and propose evidence-based strategic changes to address these challenges and improve future outcomes.
Methods: A SWOT analysis was conducted to identify the internal strengths, weaknesses, external opportunities, and threats related to the Dental Hygiene profession, gathering both quantitative and qualitative data through a survey of relevant stakeholders (Consultants, Dental hygiene graduates, dental auxiliaries, fresh dental graduates, and prospective students) using Research Electronic Data Capture (REDCap).
Results: A total of 267 respondents participated in the survey, providing insights into the current state of the Dental Hygiene profession.
Conclusion: The analysis reveals that the Dental Hygiene profession in Pakistan requires robust advocacy, increased collaboration with dentists, opportunities for higher education, and the establishment of proper legislative frameworks to prevent professional transgression beyond the scope of practice.

Objective: This study aimed to evaluate and compare the efficacies of Papacarie Duo gel, Brix 3000, Selecti-Solve gel, 2.4% sodium hypochlorite gel, and conventional rotary-mechanical method in caries removal and to evaluate the patient comfort.
Methods: It was a single-blinded, randomized, parallel-group, active-controlled trial with five arms. It was conducted at the Department of Restorative Dentistry and Endodontics, Damascus University. Seventy-five specimens were randomly allocated into five groups: chemomechanical caries removal (CMCR) using Selecti-Solve gel (G1), BRIX3000 (G2), Papacarie DUO gel (G3), or 2.4% sodium hypochlorite gel (G4), and caries excavation using conventional rotary-mechanical method (G5) (control group). The trial considered healthy patients aged 18-40. Permanent molars with class I carious lesions extending to the middle third of dentin with no pulpal and/or periodontal pathology were included. The efficacy of caries removal was considered the primary outcome measure, and the secondary outcome measures were treatment time, volumetric measurement of the cavity, and pain assessment.
Results: The majority (73.30%) of cases from BRIX3000 and conventional rotary-mechanical method groups showed complete caries removal (p = 0.982). The mean time of caries removal was the highest (17.45 ± 4.42) in the 2.4% sodium hypochlorite gel group (p < 0.05), and the lowest (6.33 ± 1.69) was in the conventional rotary-mechanical method group (p < 0.05). The mean cavity volume was the highest (18.97 ± 9.76) in the Papacarie DUO gel group, and the lowest (14.87 ± 4.76) was in the 2.4% sodium hypochlorite gel group (p = 0.506). The conventional rotary-mechanical group exhibited the highest mean score (5.40 ± 1.72) of pain (p < 0.05). However, the mean score (2.67 ± 1.11) of pain reported reduced in the BRIX3000 group.
Conclusions: CMCR agents could be a potential substitute for conventional rotary instrumentation methods, taking into account the long working time.

Aim: Assessment of interfacial gaps and mechanical impact of the materials layering between Cention Forte and Equia Forte restorations with two forms of Calcium Silicate Cements (CSCs) at the interfacial surface at two-time intervals.
Methodology: Six groups of 72 primary molars were categorized by restorative material type and CSCs: Cention Forte(C), Cention Forte without primer (Cx), and Equia Forte (EQ). All were applied over MTA Angelus powder (M) or Bio-C Repair putty (P). Restorative materials were applied immediately (subgroup A) or delayed (Subgroup B). SEM was used to detect interface gaps. EDX measured element migration from the interface at specific distances. Vickers Microhardness Tester assessed microhardness.
Results: Regarding SEM, there were no gaps between CSCs interfaces of both types (Powder and Putty) with all restorations at two-time intervals. Microhardness, there was a statistically nonsignificant difference between subgroups A & B in all groups except at 200 µm in the Cention groups (subgroup A) was significantly lower than (subgroup B) (P = 0.002, 0.03) respectively. At 400 µm in the MTA Angelus powder Group Cx, subgroup A was significantly higher than subgroup B (P = 0.003*). While Bio-C Repair putty in Group EQ (subgroup A) was significantly higher than (Subgroup B) (P < 0.0001*).
Conclusions: The delayed application of Cention Forte over two types of CSCs is useful in getting the maximum HV and, in turn, the long survival rate of the filling. Immediate application of Cention Forte without primer is better over both types of CSCs. The delayed application of Equia Forte over MTA angelus powder is more considerable.
目的:评估Cention Forte和Equia Forte修复体之间的界面间隙和材料分层的机械影响,在界面表面使用两种形式的硅酸钙水门汀(CSC),每隔两次:按修复材料类型和 CSCs 对六组 72 颗初级磨牙进行分类:Cention Forte (C)、Cention Forte(无底漆)(Cx) 和 Equia Forte (EQ)。所有材料都覆盖在 MTA Angelus 粉末 (M) 或 Bio-C 修复腻子 (P) 上。修复材料立即使用(A 组)或延迟使用(B 组)。SEM 用于检测界面间隙。EDX 测量元素从特定距离的界面迁移的情况。维氏硬度计对显微硬度进行评估:扫描电子显微镜(SEM)显示,所有修复体的两种类型(粉末和油灰)界面之间都没有间隙。显微硬度方面,除了在 200 微米处 Cention 组(A 组)明显低于 B 组(P = 0.002,0.03)外,A 组和 B 组在所有组别中均无显著差异。在 MTA Angelus 粉末 Cx 组中,400 微米处 A 亚组明显高于 B 亚组(P = 0.003*)。而 EQ 组(A 子组)的 Bio-C 修复腻子明显高于(B 子组)(P 结论):在两种类型的 CSC 上延迟使用 Cention Forte 有助于获得最大 HV 值,进而延长填充物的存活率。在两种类型的 CSC 上立即使用 Cention Forte 而不使用底漆的效果更好。在 MTA 安琪拉粉上延迟使用 Equia Forte 的效果更为显著。
