NEW APPROACHES TO LASER TREATMENT FOR ORAL PERI-IMPLANT MUCOSITIS

Aim of the study The objective of this study is to examine the impact of treatment with two simultaneous lasers on implant mucositis. Material and methods A number of 40 patients (90 implants) were included in this research. They were allocated randomly in 2 groups. Results Both variables as Pocket depth around implants (if diminished under 6 mm of depth) and the absence of clinical signs of inflammation by means the absence of measured bleeding on probing at 6 months after performing the treatment were evaluated together as parameters evaluating the success of the performed treatment, and significantly better results were observed in first group of subjects at their evaluation

THE IMPACT OF FABRICATION METHODOLOGIES ON THE FLEXURAL STRENGTH OF COMPLETE DENTURES: AN INVESTIGATION INTO TECHNOLOGICAL INFLUENCES

Aim of the study. In this study, we examined how the choice of fabrication technology impacts the flexural strength of denture bases, considering the potential long-term consequences of permanent stresses on these structures. Such stresses can eventually result in cracking, fracture, or a loss of adaptation within the prosthetic field, which undergoes dynamic changes over time. Material and methods. The flexural strength was tested on specimens made of the same material (based on thermopolymerizable PMMA), using three different technologies: the classic press packing process and traditional polymerization, the injection technology and polymerization under constant pressure and an original suction-injection process (vacuum-pressure alternation), with polymerization under continuous pressure. The actual testing of the flexural strength was carried out in collaboration with the Department of Strength of Materials within the Faculty of Civil Engineering and Architecture Timisoara. Results & Conclusions. Superior outcomes were achieved through the suction-injection method, with polymerization under sustained pressure, in comparison to injection techniques associated with polymerization under constant pressure. These results surpassed those attained through manual press packing procedures and traditional hot polymerization methods

Laser Therapy Effects on Periodontal Status: A Randomized Study Using Gaussian Network Analysis and Structural Equation Modeling Approach

Background and Objectives: This paper aims to assess the role of laser therapy in periodontitis through an innovative approach involving computational prediction and advanced modeling performed through network analysis (Gaussian graphical models—GGMs) and structural equations (SEM). Materials and Methods: Forty patients, exhibiting periodontal pockets with a minimum depth of 5 mm, were randomly divided into two groups: a control group and a laser group. Four specific indicators were measured for each tooth, namely periodontal pocket depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI), and the mean of six measured values was recorded at five time markers (baseline, 6 months, 1 year, 2 years, and 4 years). The assessment algorithm included enrollment, measurements, and differential non-surgical periodontal treatment, according to the group allocation. Scaling, root planing, and chlorhexidine 1% were conducted for the control group, and scaling, root planing and erbium, chromium:yttrium-scandium-gallium-garnet (Er,CR:YSGG) laser therapy were conducted for the laser group. Results: The main results highlight that the addition of laser treatment to scaling and root planing led to notable clinical improvements, decreasing the PPD values, reducing the BOP scores, and increasing the CAL. Conclusions: Notable relationships between the specific indicators considered were highlighted by both the GGMs and by SEM, thus confirming their suitability as proxies for the success of periodontal treatment
