Background: The current study was planned to evaluate the accuracy of dental implant placement with two different types of surgical guides: Thermoplastic and three-dimensional (3D) printed.

Materials and methods: A total of 32 implants were placed in 20 healthy, partially dentate individuals with an isolated single missing tooth. The implant sites were randomly allocated into two treatment groups: Group A (thermoplastic implant surgical guide, n = 16 implants) and Group B (3D printed implant surgical guide, n = 16 implants). All the cases in both groups were digitally planned according to a defined protocol, and a comparison of the planned and actual implant positions was performed using the medical image analysis software. The differences in the outcome variables, i.e., angular deviation (AD), 3D error at the entry, 3D error at the apex (3D EA), vertical deviation (VD), and composite deviation, were statistically analyzed.

Results: All the outcome variables showed improvements, but statistically significant improvement was shown by AD (P = 0.005), 3D EA (P = 0.01), and VD (P = 0.007). The mean and standard deviation (SD) for AD, (3D EA), and VD were 5.58° ±1.93°, 0.96 ± 0.32 mm, and 0.58 ± 0.36 mm, respectively, for group A. The mean and SD for AD, (3D EA), and VD were 3.94° ± 0.64°, 0.64 ± 0.35 mm, and 0.29 ± 0.13 mm, respectively, for group B (P < 0.05).

Conclusion: Within the limits of the study, dental implants placed using 3D-printed surgical guides were positioned clinically with greater accuracy, and fewer deviations were observed from their presurgical planned positions as compared to the thermoplastic surgical guides.

Interleukin-1β (IL-1β) is a main pro-inflammatory cytokine that is used for the assessment of treatment efficacy in periodontitis. This meta-analysis aimed to assess the effect of antimicrobial photodynamic therapy (aPDT) on Stage III-IV (severe) periodontitis-induced local IL-1β. This review study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement and registered in PROSPERO (CRD42024522546). Electronic and manual search of the literature was conducted in four databases for English articles from the first record up until June 30, 2022 comparing the effects of aPDT versus conventional scaling and root planing on IL-1β levels at different follow-up times. The mean gingival crevicular fluid level of IL-1β with 95% confidence interval (CI) was pooled using the random effect model. The I ² statistics were applied to analyze the heterogeneity of the findings. The risk of bias (RoB) was analyzed using the revised Cochrane RoB. Analysis of 11 retrieved studies revealed that after the application of aPDT, a significant reduction in IL-1β level occurred at 1-2 (standardized mean difference [SMD]: 0.29, 95% CI: -0.57-1.15; P = 0.0002), 4-6 (SMD: 0.53; 95% CI: -0.36-1.42; P < 00001), and 12-13 (SMD: 1.04; 95% CI: -0.22-2.3; P < 0.00001) follow-up weeks. The application of aPDT can serve as an effective adjunctive therapy for the treatment of Stage III-IV periodontitis. Although the results of this meta-analysis showed that increasing the session frequency of aPDT had a higher effect size, further studies without the limitations of the existing studies are required to confirm the present results.

Background: The World Health Organization (WHO) recognized chronic kidney disease as the 12^th and 17^th leading cause of death and disability in the world, respectively. End-stage renal disease (ESRD) patients undergoing dialysis are also often prone to gingival and periodontal tissue inflammation.

Aim: The aim of this study was to assess and compare periodontal status among dialysis patients with age- and gender-matched controls in Hyderabad City, India.

Materials and methods: Cases (n = 165) included people who had been diagnosed with ESRD, while controls (n = 165) were subjects accompanying cases who were matched for age and gender. The oral hygiene behavior (OHB) was assessed using the OHB Index developed by Buunk et al. Periodontal status was assessed using the Community Periodontal Index modified and loss of attachment (LOA) based on the modified WHO criteria 2013.

Results: Significantly higher means of OHB were seen among cases. Higher means of bleeding, pocket depth (PD), and LOA were seen with increasing age among males, low level of education, and presence of systemic condition among both cases and controls. The mean number of teeth with pocket depth (PD) >4 mm and the mean number of sextants with LOA >3 mm were significantly higher among cases than controls. At the same time, the gingival bleeding was significantly higher among controls. Regression analysis revealed that subjects who underwent dialysis (cases) and the presence of the systemic condition were only the significant predictors for the presence of periodontal disease.

Conclusion: The study concludes that patients undergoing hemodialysis are more prone to periodontal diseases, which are again influenced by systemic conditions.

Background: It is important to prognosticate the hard- and soft-tissue alterations in immediate and delayed implants, as inadequacy can lead to complications affecting the long-term survival of the implant. Therefore, the purpose of this study was to evaluate and compare the hard- and soft-tissue changes in immediate and delayed posterior implants with a flapless approach.

Materials and methods: With an equal allocation ratio, the study included 46 patients requiring implant treatment in the posterior segment, including the premolars and molars. Group 1 consisted of patients with immediate implants, whereas Group 2 consisted of patients who received delayed implants. The clinical parameters, including plaque index (PI), gingival index, modified sulcus bleeding index, probing depth, and soft-tissue assessment using the Testori esthetic score (TS), were evaluated at baseline, 3, 6, 9, and 12 months. Hard-tissue parameters, such as buccal bone thickness (BBT), crestal bone height (CBH), and ridge width, were evaluated radiographically with cone-beam computed tomography at baseline and 12 months posttherapy.

Results: Intragroup comparisons in both the groups showed significant differences in PI, probing pocket depth, and TS over time (P = 0.00). The mean BBT at the crest in delayed implants (1.76 ± 0.24) significantly reduced after 12 months compared to immediate implants. A significantly higher TS score was observed after 12 months in both the groups.

Conclusion: A significant difference in TS scores after 12 months was found between the two groups, with better esthetics in Group 1 compared to Group 2. However, no significant changes in BBT or CBH were observed after 12 months in Group 1.

Background: Very few studies have examined the impact of the concurrent presence of periodontitis (PD) and type 2 diabetes mellitus (T2DM) on serum Vitamin D levels, particularly in developing nations like India, and needs further investigation.

Aim: This study aims to assess the relationship between serum Vitamin D values and PD in T2DM patients and to study the correlation between socioeconomic and demographic variables that influence the serum Vitamin D levels and the extent of PD in patients with T2DM.

Materials and methods: This was a cross-sectional, hospital-based research. Medical, dental, and diet histories were obtained from the participants, and their socioeconomic status (SES) was determined. Clinical parameters - plaque index (PI), gingival index (GI), sites with gingival bleeding, probing pocket depth (PPD), and clinical attachment level (CAL) were compared among three groups -patients with generalized Stage III Grade B PD with T2DM (n=35), patients with generalized stage III Grade B PD (n=35) and healthy controls (n=35) and the clinical parameters - plaque index(PI), gingival index(GI), sites with gingival bleeding, probing pocket depth(PPD), and clinical attachment level(CAL) were measured. Biochemical tests included the evaluation of serum 25-hydroxyvitamin D (25[OH] D) and hemoglobin A1C (HbA1c) levels.

Statistical analysis: Periodontal and biochemical parameters were compared using a one-way analysis of variance across the three groups. The association between clinical parameters, SES, and 25(OH)D was examined using Pearson's correlation coefficient test and linear regression analysis.

Results: The serum 25(OH)D levels were lowest in the subjects with generalized Stage III Grade B PD with T2DM (13.54 ± 3.31 ng/mL). Furthermore, there was a significant (P < 0.01) negative correlation between serum 25(OH)D and periodontal parameters, PI (-0.442), PPD (-0.474), CAL (-0.459), sites with gingival bleeding (-0.354), and GI (-0.346) among the groups. The regression analyses showed that an increase in periodontal parameters (PI, GI, PPD, and CAL) and a higher HbA1c was linked to a lower 25(OH)D. However, the periodontal parameters and 25(OH)D levels showed no correlation with socioeconomic and demographic parameters in the study.

Conclusion: Serum Vitamin D values are negatively influenced by the synergistic effect of PD and T2DM or by the presence of PD alone. However, the association of SES on serum Vitamin D values in individuals with PD and T2DM or PD alone could not be demonstrated.

Background: The purpose of this systematic review was to assess the efficiency of allogenic bone block grafts for maxillary alveolar ridge reconstruction.

Materials and methods: An electronic literature search was conducted using the PubMed, Cochrane Library, and Google Scholar databases. In addition, manual searching was done. Randomized controlled trials (RCTs) and prospective clinical trials (non-RCTs) up to December 2022, presenting the outcomes of allogenic bone blocks in maxillary alveolar ridge reconstruction, were identified. The rate of resorption, survival rate of implants, and formation of new bone following ridge augmentation were the outcome parameters. The quality assessment of the studies included was done using Joanna Briggs Institute Critical Appraisal Tool.

Results: A total of 13 studies that matched the inclusion criteria were included. The average rate of bone resorption ranged from 0.2 to 29.2 mm, with an implant survival rate of 96.87% across the included investigations. On an average, 25.83 mm (18.6-33/mm) of new mature compact osseous tissue was discovered, including viable osteocytes in close contact with the remnant cancellous bone.

Conclusion: According to the results of the current systematic review, using allogenic bone block graft for reconstruction of atrophic maxillae appears to be an effective and reliable bone substitute for reconstruction of atrophic maxillae.

The prevalence of inherited bleeding disorders (BDs) is low in the general population (10-20 per 100,000 individuals), particularly hemophilia B cases, which may remain undiagnosed for a very long time until exposed to some surgical procedure. The dental professional must be aware of the possibility that patients with no previous history of abnormal bleeding may manifest their first bleeding episode in the dental office. Particularly as periodontists, we often encounter patients with bleeding gums and severe bleeding complications may precipitate while performing routine periodontal procedures. Hence, we must have a thorough knowledge of BDs and their management in challenging hemorrhagic situations. Management of such patients necessitates a multidisciplinary approach by involving the patient's hematologist and advanced laboratory facilities. The present case report is an attempt to discuss the diagnosis and management of a bleeding episode that occurred post periodontal flap surgery in an undiagnosed hemophilia B patient.

Background: Osseointegration depends on primary stability, and further, implant surface modifications may improve secondary stability. This randomized clinical trial evaluates whether adding a fluoride solution enhances the implant stability.

Materials and methods: Stability of dental implants with two different types of surface treatments was compared utilizing resonance frequency analysis (RFA). Twelve patients were recruited: eight females and four males with an average age of 58.3 years and they received either double acid etched implants (control: Porus Implant, Sistema Conexão) and double acid etched implants containing fluoride on their surfaces (test: Porus Nano Implant, Sistema Conexão). Each patient received one implant from the test category and another implant from the control category, resulting in 24 implants in this study. RFA, utilizing Osstell was used to assess the implant stability, immediately after the placement of implant and 15, 30 and 45 days post-implant placement.

Results: At the initial time, there was no difference between the test and control groups regarding the ISQ. However, after 15, 30, and 45 days, ISQ values for the test group were significantly higher than the control group. When using implants without fluoride addition, it was observed that after 15 days, the ISQ values were lower than those found at the initial time, but after 30 days, values matched the initial. Concerning the test group results, the ISQ values from T0 (immediately after implant placement) to T3 (45 days after implant placement) always increased from every period of evaluation.

Conclusions: It was concluded that double acid etched implants with surfaces containing fluoride solution increases the implant stability quotient, compared to implants with fluoride-free double acid etched surfaces.
