The growing complexity of care and healthcare workforce shortages in the Netherlands necessitates exploring interprofessional collaboration (IPC). However, the predominant single-professional education may result in a professional identity (PI) among healthcare students, which may not support successful IPC. Internships in student-run interprofessional learning wards (SR-IPLW) could foster interprofessional identity (IPI) development.

Low-level laser treatment's ability to reduce dry socket pain.

Acta Odontol Scand

November 2024

Department of Biomedical and Surgical and Biomedical Sciences, Catania University, Catania, Italy.

Article Synopsis
  • After a tooth extraction, a common complication known as dry socket can lead to severe pain and hinder healing, traditionally treated with antiseptic dressings like Alveogyl.
  • This study investigates the effectiveness of Low-Level Laser Therapy (LLT) compared to conventional treatments in alleviating the symptoms of dry socket.
  • The meta-analysis found that LLT significantly reduces pain associated with alveolitis more effectively than Alveogyl, although it stops short of recommending laser therapy as a complete replacement for traditional methods.

Objectives: This study compares the restoration of single-tooth implants with screw-retained lithium-disilicate hybrid-abutment crowns and single-tooth lithium-disilicate crowns adhesively bonded to hybrid abutments with regard to objective clinical and subjective patient-specific evaluation criteria over a time of observation of 3 years.

Materials And Methods: Two bone-level implants were placed in contralateral sides of the same jaw in 10 patients, each with two single-tooth gaps. After osseointegration, implants were uncovered and an impression was taken.

Objective: To evaluate the possibility of improving the effectiveness of early postoperative healing in patients after surgical interventions on periodontal tissues due to the topical application of alginate plates with a complex of antimicrobial peptides and cytokines.

Materials And Methods: 40 patients who underwent periodontal surgery were examined: operations aimed at bone tissue regeneration; mucogingival operations (elimination of gum recession), corticotomy with osteoplasty, apical surgery. The patients were randomly divided into 2 groups of 20 people (main and control).

Article Synopsis
  • The study investigated the effectiveness of riboflavin, nano-micelle curcumin, and hydrogen peroxide, both alone and with light treatment, on reducing harmful biofilms made up of Streptococcus mutans and Lactobacillus acidophilus.
  • Treatment involved antimicrobial photodynamic therapy (PDT), where various methods were applied to biofilms formed on treated enamel surfaces, followed by assessments of biofilm reduction and mineral loss.
  • Results indicated that nano-micelle curcumin was the most effective, achieving a 40% reduction in biofilm, and suggested that using natural photosensitizers like curcumin could be significant in combating tooth decay-causing bacteria.

Statement Of Problem: Systematic reviews to determine the effectiveness of oral rehabilitation with trans-sinus dental implants in patients with an atrophic maxilla are lacking.

Purpose: The purpose of this systematic review was to determine the effectiveness of trans-sinus dental implants installed in patients with an atrophic maxilla.

Material And Methods: Searches were conducted in 5 databases including the nonpeer-reviewed literature up to March 2024 by 2 independent reviewers according to established inclusion and exclusion criteria and according to the question: Can trans-sinus implants be a suitable option for the rehabilitation of the atrophic maxilla? The meta-analysis was carried out using the Revman software program for the variables implant loss and marginal bone loss using a 95% confidence interval.

Background: It is well known that in bidimensional photography the orientation of the head is fundamental to obtain a correct reproduction of the subject. Even minimal errors in yaw, roll and pitch of the head can be cause of unreliability of the photography itself. This is not the case in three-dimensional photography in which head positioning may have no influence on the reliability of the results since on the computer the 3D reconstruction of the face can be oriented as desired, allowing any small errors to be corrected.

Background: The present study aimed to determine the cumulative effect of two photodynamic therapy methods with methylene blue and indocyanine green and two topical fluoride therapy methods with fluoride varnish and silver diamine fluoride alone and in combination on the microhardness and topography of demineralized enamel and cementum surfaces.

Materials And Methods: Seventy-two sound human teeth were selected, and their buccal and lingual surfaces were assigned to two main groups of enamel and cementum using simple randomization. The initial surface hardness (SH) of the enamel and cementum in each sample was determined using a micro-Vickers hardness tester using a 200-g force in 10 s.
