This study aimed to evaluate the clinical and radiographic outcomes of premixed bioceramic putty as a direct pulp capping in primary molars over a 12-month follow-up period.

Methods

This study included forty primary molars with deep occlusal carious lesions, whose removal resulted in pulp exposure. They were treated with direct pulp capping using premixed bioceramic putty. All teeth were covered using high viscosity glass ionomer and immediately restored with stainless steel crowns to ensure proper seal. Clinical examinations were conducted at 3, 6, 9, and 12 months, while radiographic examinations were conducted at 6 and 12 months follow up interval.

Results

Forty teeth were available for follow up. By the end of the 12 months, the overall clinical and radiographic success was 87.5%.

Conclusions

Radiographic and clinical outcomes of premixed bioceramic putty could suggest it as an effective …

Statement of problem

Intraoral scanning of complete arch implant-supported prosthesis is still not predictable in all scenarios. Photogrammetry was introduced to overcome physical and anatomic limitations. The use of a new intraoral scanner combined with photogrammetry technology in a simplified workflow may improve the ease of fabrication and accuracy of complete arch implant-supported prostheses.

Purpose

The purpose of this clinical study was to evaluate the degree of trueness of a conventional intraoral scanner (IOS) and an intraoral photogrammetry scanner (IPS) for complete arch implant-supported prostheses.

Material and methods

Participants who had received 4 implants in an edentulous arch for an implant-supported complete arch fixed dental prosthesis were recruited. Three recordings were obtained for each participant: IOS, IPS (tests), and a conventional splinted open-tray impression (reference …

This study aimed to evaluate the clinical performance (degree of trueness) of a novel scan body “tooth-modified Scan body” (TMSB)& conventional scan body (CSB) in implant-supported full arch screw retained cases.

Methods

Seven edentulous arches (two maxillae, five mandibles) in 6 patients were rehabilitated with monolithic zirconia screw-retained implant prostheses supported by 4 (n = 1) and 5 implants (n = 6) for a total amount of 34 implants. Implant locations were scanned by intra-oral scanner (IOS) using two types of scan bodies, conventional scan bodies (CSB) in group (1) and tooth-modified scan bodies (TMSB) in group (2). 68 implant positions (representing the total sample size) were captured and compared to the relative reference scans regarding angular and Euclidian deviation (ΔEUC).

Results

The ΔEUC deviation Of TMSB group had lower values (M = 61.46, SD = 42.12) than that …

To evaluate early versus conventional loading in immediate implants for molars. This study aims to answer the following PICO (Patient, Intervention, Comparison, and Outcome) question: In patients over 18 years of age, does early loading of immediately placed implants in molar areas result in a similar implant survival rate and marginal bone loss as conventional loading?

Methods

Twenty-seven patients (15 women and 12 men) received a total of 30 implants immediately after molar extraction. The surgical treatment protocol entailed atraumatic tooth extraction without flap elevation. Non-invasive quantitative analyses were used to assess implant stability. After an uneventful healing period, the 30 implants were restored with screw-retained monolithic zirconia prosthesis, half of which after 6 weeks (G1) and the other half after 3 months (G2).

Results

Regarding the survival rate, the Kaplan–Meier and log-rank …
