Background and study aims
This study aims to find out if using an antimicrobial treatment called HybenX (HY) along with standard dental cleaning (SRP) provides extra benefits for people with severe gum disease (periodontitis). Researchers will compare the results of using both treatments together versus using only the dental cleaning.
Who can participate?
Adults over 18 years old with severe gum disease (stage III or IV periodontitis), good general health, and at least five natural teeth per quadrant can participate. Participants must have at least two sites with a pocket depth greater than 4 mm.
What does the study involve?
Participants will receive a full-mouth examination (excluding wisdom teeth) at the start and after three months. In each participant, two randomly chosen sections of the mouth will be treated with both SRP and HY, while the other two sections will receive only SRP. The study will be conducted at a single center.
What are the possible benefits and risks of participating?
Participants will benefit from free complex periodontal assessment and treatment. Risks include potential allergic reactions and chemical burns from HybenX, and complications from anesthesia such as temporary loss of sensitivity, pain at the puncture site, and local hematoma. There may also be other unpredictable risks.

| Scientific title | The use of a local desiccant antimicrobial agent in periodontal therapy: a randomized clinical trial |
| Study acronym | ULDAAPT |
| Study objectives | The study aimed to analyze whether there are differences in clinical efficacy by using a commercial desiccant antimicrobial agent Hybenx in combination with subgingival mechanical instrumentation (SRP) vs. SRP alone for the treatment of severe periodontitis cases during a three-month interval. |
| Ethics approval(s) |
Approved 03/12/2024, Ethics Committee of the County Emergency Hospital (str. Clinicilor nr. 3-5, Cluj-Naopca, 400006, Romania; +40 264597256; secretariat@scjucluj.ro), ref: 46170 |
| Health condition(s) or problem(s) studied | Periodontitis |
| Intervention | Each patient will receive an initial complete full-mouth clinical examination, excluding wisdom teeth (baseline assessment). Periodontal examinations will be performed in the clinic setting with standard equipment: dental mirror, UNC-15 periodontal probe, with millimiter markings (Hu-Friedy, Chicago, IL, USA). Based on the evaluated clinical periodontal parameters: probing depth (PD), gingival recession (GR), clinical attachment loss (CAL), and bleeding on probing scores the diagnosis of periodontitis, will be established, according to the 2018 classification system developed by the EFP and AAP. Gingival inflammation will be assessed using the Gingival Bleeding Index (GBI), and oral hygiene will be quantified with the Oral Hygiene Index (OHI) scores. The periodontal diagnosis will be set based on the presence of interdental CAL at a minimum of two non-adjacent teeth, or buccal /oral CAL ≥ 3 mm associated with PD > 3 mm. The identified periodontitis cases will be divided into four stages based on the severity of the periodontal tissue destruction: stage I (mild) periodontitis; stage II (moderate) periodontitis; stage III and stage IV (severe and very severe) periodontitis. Cases that do not meet periodontitis case definition criteria will be classified as either gingivitis or periodontally healthy cases. After initial clinical periodontal assessment and diagnosis, a standard, stepwise treatment plan will be provided for each patient based on the available recommendations, including the first-step of the periodontal therapy, comprising of patient behavioral change interventions, supragingival biofilm control, and management of modifiable risk factors. Cause-related therapy consisting of mechanical subgingival instrumentation will be initiated only after the first-step therapy endpoints will be achieved. For each periodontitis patient, two hemiarches of the four hemiarches will be treated with subgingival mechanical instrumentation (SRP) plus HybenX and will be included in the test group (SRP plus HY group), while the other two hemiarches that will receive SRP alone will be included in the control group (SRP group). After completing the study, patients will receive the other therapy steps as planned. The hemiarches (hemiarches 1 and 4) will be randomly assigned to one of the therapies (SRP plus HY or SRP alone) based on a randomization table. On the first treatment day, hemiarches 1 and 4 will be treated following random allocation (test therapy or control therapy); the following day, the other treatment will be applied for the other two hemiarches (hemiarches 2 and 3). The records of the participants will not contain any mention of treatment allocation. The list containing allocation numbers and patient’s names will be kept by the senior periodontologist, who is also responsable for patient’s recruitment. The baseline examination and the treatment will be provided by two investigators, and re-evaluations will be performed by other investigators. Investigators conducting the follow-up examination and the statistician will not be aware of the treatment type received by patients. HybenX application protocol according to the manufacturer: • Dry the tooth • Apply HybenX® via cannula before scaling and root planing in pockets deeper than 5 mm. • Wait 10–30 seconds • Remove HybenX® with supragingival and subgingival to the base of periodontal pockets suction and rinse with water until clear |

Count of interproximal probing depths equal to 5 mm is measured using a periodontal probe at six sites per tooth, summing the number of interproximal sites with PD = 5 mm 7. Count of total probing depths greater than or equal to 6 mm is measured using a periodontal probe at six sites per tooth, summing the number of sites with PD ≥ 6 mm 8. Count of interproximal probing depths greater than or equal to 6 mm is measured using a periodontal probe at six sites per tooth, summing the number of interproximal sites with PD ≥ 6 mm 9. Oral Hygiene Index (IHI) score is measured using a dental plaque detector at four sites per tooth, calculated as the percentage of plaque-positive sites over total sites 10. Gingival Bleeding Index (GBI) score is measured using a periodontal probe at four sites per tooth, calculated as the percentage of bleeding sites over total sites |
