Clinical Evaluation of the NeoPill Device for Reduction of Oral Bacterial Load in Patients With Fixed Orthodontic Appliances

This study evaluates the effectiveness of the NeoPill oral hygiene device in reducing oral bacterial load in adults wearing fixed orthodontic appliances. Maintaining oral hygiene is challenging for orthodontic patients due to limited access around brackets and wires, and current solutions often rely on chemical-based products and disposable tools. NeoPill is a reusable, battery-operated oral device designed to provide mechanical cleansing of the oral cavity. In this single-arm clinical evaluation, participants will undergo oral swab sampling before and immediately after a single 30-second application of the NeoPill device. The primary outcome is the change in aerobic bacterial load, measured as colony-forming units (CFUs), between pre- and post-treatment samples. Participants will also complete a short questionnaire to assess usability, comfort, and overall experience with the device. The study aims to generate preliminary clinical and user-experience data to support further development of the NeoPill device.

Clear Aligner Cleaning: Brushing, Chlorhexidine, and BlueM Effects on Oral Microbial Ecology and Periodontal Indices

This randomized crossover study will assess how three aligner-cleaning methods affect early supragingival oral microbial ecology and periodontal health in adults using clear aligners. Each participant will complete three (1-month) periods in a randomized sequence with (1-week) washouts between periods: 1. Mechanical toothbrushing with fluoride toothpaste (control), 2. Chlorhexidine (CHX) mouthwash, and 3. an oxygen-based cleanser (BlueM). Primary ecological outcomes focus on early dysbiosis indicators Fusobacterium nucleatum and Prevotella intermedia measured on retrieved aligner inner-surface biofilm and on supragingival plaque at the gingival margin. Secondary outcomes include periodontal indices (plaque index, gingival index, bleeding on probing) at index teeth and the host inflammatory marker MMP-8 in matrix-paired extracts (plaque and aligner). Study visits occur at baseline and at the end of each 1-month period. Supragingival plaque is collected from the upper and lower first molars and central incisors; used aligners are swabbed immediately after removal. Participants are instructed to wear aligners about 22 hours/day, change trays every 10 days, remove aligners for meals and oral hygiene, and drink only water while aligners are in. Laboratory procedures include blinded culture enumeration under coded labels (performed by a single trained operator, FA), confocal laser scanning microscopy, and RNA isolation with species-specific qRT-PCR; microscopy is conducted unblinded after decoding. The study will determine whether chlorhexidine or an oxygen-based cleanser produces more favorable early ecological changes and periodontal outcomes than mechanical brushing alone in clear aligner therapy.

The researchers will compare the changes that each one causes in salivary pH, dental biofilm pH, dental biofilm bacterial proliferation and dental biofilm microbiome.

0.2% Chlorhexidine vs MicroRepair ABX in Gingivitis

Gingivitis is the most common form of reversible gum disease, caused by the accumulation of dental plaque. It leads to inflammation of the gums, bleeding, and discomfort, but it can be managed and reversed with professional dental cleaning and proper oral hygiene. Chlorhexidine 0.2% mouthwash is considered the "gold standard" in reducing plaque and gingival inflammation. However, its long-term use may cause side effects such as tooth staining, changes in taste, and irritation of the oral tissues. MicroRepair® ABX mouthwash, which contains biomimetic zinc-hydroxyapatite microcrystals with antibacterial components, has shown promising properties in reducing plaque and supporting gum health, with potentially fewer side effects. This randomized controlled clinical trial will compare the effectiveness of 0.2% chlorhexidine mouthwash and MicroRepair® ABX mouthwash, both used after professional dental cleaning, in patients with plaque-induced gingivitis. Forty participants will be randomly assigned to one of the two treatments for 14 days. The primary outcome will be the change in gum pocket depth, measured as Probing Pocket Depth (PPD). Secondary outcomes include changes in plaque accumulation, measured as Full-Mouth Plaque Score (FMPS); gum bleeding, measured as Full-Mouth Bleeding Score (FMBS); attachment of the gums to the teeth, measured as Clinical Attachment Level (CAL); gum recession, measured as Recession (REC); tooth staining, measured with the Lobene Stain Index; tooth sensitivity, measured with the Schiff Air Index; taste alterations assessed through a validated questionnaire; and salivary levels of activated Matrix Metalloproteinase-8 (aMMP-8), a biomarker of gum inflammation. The goal of this study is to determine whether MicroRepair® ABX is as effective as chlorhexidine 0.2% in treating plaque-induced gingivitis, while offering better tolerability and fewer side effects.
