TUN is an effective procedure in treating localized and multiple GR defects. Limited evidence is available comparing TUN to CAF; however, CAF seemed to be associated with higher percentage of CRC than was TUN when the same grafts (connective tissue or acellular dermal matrix) were used in both techniques.

Background:The crestal bone level and soft tissue dimension are essential for periodontal diagnosis and phenotype determination; yet, existing measurement methods have limitations. The aim of this clinical study was to evaluate the correlation and accuracy of ultrasound in measuring periodontal dimensions, compared to direct clinical and cone-beam computed tomography (CBCT) methods. Methods:A 24-MHz ultrasound probe prototype, specifically designed for intraoral use, was employed. Periodontal soft tissue dimensions and crestal bone levels were measured at 40 teeth and 20 single missing tooth gaps from 20 patients scheduled to receive a dental implant surgery. The ultrasound images were interpreted by two calibrated examiners. Inter-rater agreement was calculated by using inter-rater correlation coefficient (ICC). Ultrasound readings were compared with direct clinical and CBCT readings by using ICC and Bland-Altman analysis. Results:The following six parameters were measured: 1) interdental papilla height (tooth), 2) mid-facial soft tissue height (tooth), 3) mucosal thickness (tooth), 4) soft tissue height (edentulous ridge), 5) mucosal thickness (edentulous ridge), and 6) crestal bone level (tooth). Intra-examiner calibrations were exercised to achieve an agreement of at least 0.8. ICC between the two readers ranged from 0.482 to 0.881. ICC between ultrasound and direct readings ranged from 0.667 to 0.957. The mean difference in mucosal thickness (tooth) between the ultrasound and direct readings was −0.015 mm (95% CI: −0.655 to 0.624 mm) without statistical significance. ICC between ultrasound and CBCT ranged from 0.654 to 0.849 among the measured parameters. The mean differences between ultrasound and CBCT range from −0.213 to 0.455 mm, without statistical significance. Conclusion:Ultrasonic imaging can be valuable for accurate and real-time periodontal diagnosis without concerns about ionizing radiation.

The main goal of dental therapy is to enhance and maintain the general health and well-being of patients (Chapple & Wilson, 2014). Dental extraction is indicated when teeth cannot be maintained in a status compatible with adequate aesthetics, function and/or health, or for strategic reasons (Kao, 2008 ; Tonetti et al., 2000). Beyond its potential impact in quality of life, tooth extraction causes a local physiologic disruption that results in an initial inflammatory response and, subsequently, a variable degree

Congruent with current global trends, a steady increase in implant therapy use is expected in developed countries until the year 2026 (Elani, Starr, Da Silva, & Gallucci, 2018). While implant therapy has been proven as a viable method for tooth replacement, a plethora of variables may play a significant role in its biological, functional, and esthetic outcomes. Some of these critical factors are related to

Background: Incidence and severity of postoperative complications are key elements in determining the risk‐benefit relationship of any surgical procedure. The aim of this retrospective study was to assess and categorize the postoperative complications that occur following, and are associated with, oral, periodontal, and implant surgeries. Methods: A total of 3,900 patients who underwent surgical procedures including, but not limited to, sinus floor elevation, guided tissue regeneration, crown lengthening, implant placement, soft tissue graft, open flap debridement or surgical removal of impacted teeth were included. Postoperative complications were recorded and graded based on impedance to routine daily activity and favorable surgical outcomes. Regression models were generated to evaluate correlations between complication types, as well as between patient/surgical characteristics and the incidence of complications. Results: Surgical removal of impacted teeth and lateral sinus floor elevation had the highest incidence and severity of complications. Postoperative dentinal hypersensitivity (5.7%) was the most frequent complication, followed by excessive pain (4.1%), and moderate postoperative bleeding (3.5%). Based on the devised grading system described in this paper, the complications were 11.1% of Grade I, 3.3% of Grade II, 8.3% of Grade III, 0.1% of Grade IV, and no complications recorded under Grades V or VI. Conclusions: Surgical removal of impacted teeth and lateral sinus floor elevation are more prone to more severe complications compared with other procedures. Additionally, complications that do not impede favorable surgical outcomes and/or routine daily activity are the most likely to occur. Smoking and diabetes are generally associated with postoperative complications.

Objectives:The purpose of this review was to provide a novel perspective utilizing an assessment of biomarkers to evaluate the impact of stress-related disorders on the progression of periodontal disease and evaluate the growing body of evidence of stress as a risk indicator for periodontal disease progression.Methods: Cross sectional, case control, and biomarker studies associating psychological disorders and periodontal disease were included in the literature search. Computational studies, animal studies, reviews, and studies lacking healthy controls were excluded. Electronic and manual literature searches were conducted by two independent reviewers in several databases as well as a manual search for relevant articles published up to January 2018.Results: Twenty-six articles fulfilled the inclusion criteria and were included in the qualitative synthesis. Relationships between stress-related disorders and serum and salivary biomarkers such as cortisol, dehydroepiandrosterone (DHEA), chromogranin A (CgA), and pro-inflammatory cytokines were identified.Conclusions: Use of salivary pro-inflammatory cytokines alone is not sufficient for identification of periodontal disease severity/progression with or without the presence of stressassociated diseases. Keeping in mind the limitations of this review, a positive qualitative *

Objective To study the performance of 2–3 posterior bone‐level dental implants constructed with either three non‐splinted crowns (NSC), three splinted crowns (SC), or a 3‐unit implant‐supported bridge over two implants (ISB). Material and methods Patients treated with three metal‐ceramic NSC, SC, or an ISB were included in the present retrospective study. Implant survival and success rate as well as all biological and technical complications were collected. The cost associated with each of the treatment options was evaluated in the comparative analysis. Results One hundred and forty‐five patients (40 NSC, 52 SC, and 53 in the ISB) receiving 382 bone‐level implants (120 NSC, 106 ISB, and 156 SC) were included (mean follow‐up of 76.2 months). Lack of success was observed in 33.8% of the total patient sample, being lower in the ISB group. Implant survival rates were 92.5% in the NSC, 100% in the ISB, and 88.5% in the SC, with significant difference noted between the ISB and SC (p = 0.01). Overall, 9.9% of the total implants were found to have peri‐implantitis (PI), with 16.7% in the SC, 7.5% in the NSC, and 2.8% in the ISB. Patients presenting prosthodontic complications were significantly higher in NSC (32.5%) than ISB (13.2%) and SC (15.4%). The total cost of the ISB group was significantly lower when compared to the NSC and SC groups (p < 0.001). Conclusions An 3‐unit implant‐supported bridge restoring 2 implants seems to present the most ideal long‐term therapeutic solution, among the investigated approaches in this study, in rehabilitating a 3‐unit edentulous area.
