Aim: To assess the improvement of the oral health-related quality of life in patients who received Corticobasal^® implant-supported prostheses.

Materials and methods: A cross-sectional study design was conducted using a structured survey based on the validated oral health impact profile-14 (OHIP-14) questionnaire, with the addition of knowledge questions to fulfill the study requirements. All the patients who planned to receive Corticobasal^® implant-supported prostheses (BCS^®, Dr. Ihde Dental AG, 8737 Gommiswald, Switzerland) at Narsinhbhai Patel Dental College and Hospital were asked to participate in the study after screening for the inclusion and exclusion criteria. The questionnaire was distributed and filled out before and six months after treatment for section C. Data were analyzed using SPSS 17.0 version. A paired t-test was used to analyze the average of all the OHIP-14 items (pretreatment vs posttreatment), while gender differences in total OHIP scores were analyzed using an independent-samples t-test. A p-value of < 0.05 was considered statistically significant. Descriptive statistics were presented in terms of tables and graphs.

Results: A total of 82 patients (68.3% females, 31.7% males) participated in the study. A significant improvement was reported with the use of the Corticobasal^® implant treatment (p = 0.0001), with no gender variation (p = 0.1341). Seventy-eight participants (95%) were very satisfied with the treatment's time, while 97.5% showed their interest in recommending the treatment modality. The majority of the participants knew about the treatment modality from social media. The participants reported high satisfaction with the treatment and overall outcomes.

Conclusion: Corticobasal^® implant treatment modality significantly improves the patient's quality of life with a reported enhancement in the patients' functional abilities and psychosocial well-being and reduced functional limitation.

Clinical significance: Corticobasal^® implant treatment is a reliable treatment option for rehabilitation patients presented with compromised bone support, with reported improvement in patient quality of life.

Aim: This study aimed to evaluate the treatment difficulty of impacted maxillary canines by using the KPG index and qualitative measurement of the surrounding alveolar bone based on Hounsfield Unit (HU).

Materials and methods: A retrospective cross-sectional analysis was conducted on 115 Cone Beam Computed Tomography (CBCT) scans of patients aged 13 years or older with impacted maxillary canines. The KPG index was used to assess spatial position in three planes. Bone density was measured on buccal, palatal, mesial, and distal surfaces at cervical, middle, and apical root levels. Data were analyzed using SPSS v26, with significance set at p < 0.05.

Results: Most impactions were palatal (74.78%), unilateral (58.26%), and more frequent in females (69.6%) than males. According to the KPG index, 49.6% were classified as "Difficult," followed by "Moderate" (33.9%). Bone density was highest at the apical root third and increased with age, though no significant gender or impaction-type differences were observed. KPG scores and bone density values showed no significant correlation.

Conclusion: Most impacted maxillary canines were classified as "difficult" based on the KPG index. Bone density was highest apically and increased with age, but showed no correlation with KPG scores, highlighting the need for independent evaluation of both factors in treatment planning.

Clinical significance: Integrating the 3D-based KPG index with bone density measurements enables earlier and more accurate prediction of treatment difficulty in impacted maxillary canines, leading to better treatment planning and improved patient outcomes.

Aims: The aim of this study was to measure Steiner's cephalometric norms for the Kazakh adult population representing the indigenous population of Kazakhstan and compare them with published measurements from selected ethnic groups.

Materials and methods: A cross-sectional study was conducted on 120 adult Kazakh patients, 60 males and 60 females, aged 16-35 years, with normal class I occlusion, a balanced profile, and no previous orthodontic treatments. Steiner's cephalometric norms were measured from lateral cephalometric radiographs.

Results: Most of the Kazakh cephalometric parameters did not significantly differ from Steiner's (Caucasian) norms. Although SNB (angle) and U1-NA (angle) were statistically significantly less than the presented Caucasian norms. In contrast, parameters such as L1-NB (angle) and L1-NB (line) statistically significantly exceeded Steiner's norms. We found slightly protruding upper jaws, a characteristic of Kazakhs with normal occlusion. Specifically, the ANB angle of 2.8°, which slightly exceeds Steiner's norms, indicated the dominance of the class II bite. Various measures differed between Kazakh males and females, including angles U1-NA, L1-NB, Occl.-SN, GoGn-SN, and the position of the lips relative to the S-line.

Conclusion: We established the cephalometric norms of the Kazakh population and highlighted similarities and differences with the Caucasian population (as a representative of their geographical neighbors) and other selected populations. Our data will significantly support and improve the diagnosis and treatment of the Kazakh adult population.

Clinical significance: Considering ethnic-specific craniofacial morphology is essential for achieving effective and lasting orthodontic outcomes. Our findings support the need for national cephalometric standards to improve diagnosis and treatment planning for the Kazakh population.

Aim: The aim of this study was to assess the impact of oral implants with three different thread designs on marginal bone loss using cone-beam computed tomography (CBCT).

Materials and methods: A total of 45 participants between the ages of 25 and 45 years were included in this study. The first round of periodontal treatment was administered to each participant. After performing an osteotomy, implants were inserted into the osteotomy site. All participants were randomly divided into three groups, with 15 participants in each group as follows: Group I: Participants received implants with spiral thread design, group II: Participants received implants with crestal microthreads design, and group III: Participants received implants with dual-fit implant design. Using the CBCT, radiographic examinations were performed at baseline, 3 months, and 6 months. In all directions (mesial, distal, buccal, and palatal), the crestal bone level circumference surrounding the implant was measured. All data were recorded and statistically analyzed.

Results: The mean marginal bone level at baseline in group I was 4.78 ± 0.06, group II was 4.96 ± 0.12, and group III was 5.04 ± 0.18. The mean marginal bone level at 3 months in group I was changed to 5.24 ± 0.10, group II was changed to 5.60 ± 0.09, and group III was changed to 5.71 ± 0.18. The least mean marginal bone loss was found in group I, which was 5.40 ± 0.14, group II was 6.12 ± 0.04, and group III was 6.46 ± 0.10. A significant difference was found among three different implant thread designs. And post hoc reveals the significant difference found between group I vs group II and group I vs group III.

Conclusion: In conclusion, implants with spiral thread design exhibited significantly less marginal bone loss than those with implants with crestal microthreads design and implants with dual fit implant design.

Clinical significance: Thread design affects bone loss primarily by the way it transmits mechanical stress to the surrounding bone. In order to avoid high stress concentrations around the implant neck, which are linked to bone resorption, an optimized design is necessary. The surface area for bone-implant contact is increased by some thread patterns, which can enhance stability and osseointegration and lessen bone loss.

Aim: This study evaluated the amount of bone regeneration and its microarchitectural integrity in peri-implant gaps in rabbits treated with one of the following approaches: Bovine bone combined with hyaluronic acid (HyA), bovine bone alone, or left untreated as an empty defect.

Materials and methods: Thirty adult male New Zealand White rabbits were included in this study. In each group (n = 10), a critical bone defect (6 mm diameter × 4 mm depth) was surgically prepared using a trephine bur under copious saline irrigation in the femoral condyle bone. A dental implant was subsequently placed into each defect. The peri-implant defects were left untreated (no biomaterial), filled with bovine bone alone, and filled with bovine bone combined with (HyA) in groups I, II, and III, respectively. All rabbits were randomly selected for euthanasia after 2 months, implant stability, and marginal bone loss (MBL) were evaluated. Then, the bone samples were processed for histological analysis.

Results: The highest Implant stability after 2 months was recorded with the group bovine bone combined with HyA (74.69 ± 0.75), followed by the bovine bone alone group (70.25 ± 0.82), and the lowest implant stability in a control group (65.10 ± 0.77), (p < 0.001*), which was supported by a significant difference in MBL between groups (p < 0.001*). The highest MBL was measured in the control group (0.63 ± 0.15). The percentage of newly formed bone in the grafted groups was significantly higher compared to the control group (4.10 ± 0.14) (p < 0.05), as measured by histomorphometry.

Conclusion: The combination of HyA with bovine bone exhibits a combined effect promoting bone regeneration and graft replacement. This approach enhances osseointegration of the implant.

Clinical significance: The use of HyA in conjunction with bovine bone improves both the rate and quality of newly formed bone potentially increase the osseointegration of the implant and reducing alveolar ridge resorption.

Aim: This study aimed to evaluate the glutathione, fluoride, and citronella gels on reducing the shear bond strength (SBS) of ceramic brackets to facilitate the debonding process and reduce enamel damage and chair time.

Materials and methods: Eighty extracted human premolar teeth bonded with ceramic brackets were divided equally into four groups according to the type of solvent used (N = 20 in each group): Control group, glutathione group, fluoride group, and citronella group. The gel solvents were applied using a syringe and left around the bracket for 10 minutes. Shear bond strength was then measured using a universal test machine, and adhesive remnant index (ARI) scoring was conducted. Scanning electron microscope (SEM) images were used to assess the effects of these agents on the enamel surface.

Results: Statistically significant differences in SBS values were observed among all groups (p ≤ 0.001). The glutathione gel group exhibited the lowest SBS values, followed by the citronella gel group, the fluoride gel group, and the control group. Adhesive remnant index scores were the lowest in the glutathione gel group, indicating minimal to no adhesive remaining on the enamel surface. Scanning electron microscope images revealed that the enamel surfaces of teeth treated with the glutathione gel group were the smoothest and showed no visible signs of enamel damage after the debonding of ceramic brackets.

Conclusion: The application of specific chemical solvents, glutathione gel, citronella gel, and fluoride gel can significantly reduce the SBS of ceramic brackets. Among these, the glutathione gel group was the most effective in lowering SBS, minimizing adhesive remnants on enamel, and preserving enamel integrity postdebonding process.

Clinical significance: Debonding ceramic brackets increased the risk of enamel damage. This study evaluates the effect of various chemical solvents on reducing the SBS of ceramic brackets to facilitate the debonding process and reduce enamel damage and chair time.

Aims: This study aimed to extract nanoparticles from the bones of the snakehead fish (Channa striata) and evaluate their physicochemical characteristics.

Methods: High-speed blending and ball milling techniques were employed for the extraction process. The morphological features, crystalline structure, and elemental composition of the resulting nanoparticles were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray fluorescence for both qualitative and quantitative analysis.

Results: The results indicated that fish bone milled for 7 hours at 600 rpm produced an average particle size of 38.68 nm. The calcium oxide and phosphate contents were found to be 62.14% and 35.96%, respectively. The calcium phosphate compound derived from the fish bone exhibited 100% crystallinity.

Conclusion: Nanoparticles from the bones of the snakehead fish (Channa striata) have a significant profile to be used for vital pulp therapy.

Clinical significance: The presence of calcium and phosphorus elements, along with the distinct diffraction pattern of hydroxyapatite, as well as the particle morphology and size, suggests that this compound holds potential as an alternative material for pulp capping.

Aim: To systematically review the role, implementation, and impact of governance, risk management, and compliance (GRC) practices in healthcare systems, identifying their benefits, barriers, and strategic approaches to enhance healthcare delivery and system sustainability.

Materials and methods: A systematic review was conducted in accordance with PRISMA 2020 guidelines and registered with PROSPERO. The studies from Jan 2010 to Mar 2025 were sourced from PubMed, MEDLINE, Google Scholar, and gray literature. Eligible studies examined GRC in health care using qualitative, quantitative, or review designs. Inclusion of review studies was critically assessed due to potential redundancy and bias. Thematic synthesis was employed to extract and organize findings across implementation strategies, settings, stakeholders, and outcomes, including care quality, safety, compliance, and organizational performance. Risk of bias was evaluated using tools appropriate to each study design.

Results: Out of 85 screened records, 22 studies met the inclusion criteria: Three systematic reviews, one scoping review, four cross-sectional studies, four narrative reviews, four editorials/expert commentaries, five conceptual or policy papers, and one perspective article. Settings ranged from primary care institutions to national-level healthcare systems across the Netherlands, Australia, the UK, Italy, the USA, and international contexts. Integration of GRC was positively associated with improved patient safety, care quality, regulatory compliance, organizational efficiency, and financial outcomes. Key enablers included leadership support, stakeholder engagement, and tailored implementation strategies. Common barriers were cultural resistance, limited resources, concerns over data privacy, low trust in digital technologies, and the absence of standardized frameworks. Improved digital governance and cybersecurity contributed to better technology integration and long-term system sustainability.

Conclusion: Effective implementation of GRC practices in healthcare systems contributes to improved care quality, patient safety, and operational sustainability. Customization to local contexts and active involvement of stakeholders are essential for optimizing the impact of GRC frameworks.

Clinical significance: The study highlights the growing need for structured GRC integration in health care to address digital transformation challenges. Findings support its clinical translational value by emphasizing safer, more efficient, and regulation-compliant healthcare delivery, thereby contributing to long-term system resilience and global health security.
