Clinical Trial Summary

The main objective is to analyze post-surgical periodontal healing after conventional periodontal surgery where an absorbable suture coated with clorhexidine (Novosyn Clorhexidine) versus conventional sutures without chlorhexidine (Novosyn) will be used a pilot randomized clinical study has been designed. Up to authors´ knowledge until now there are no studies to evaluate periodontal healing after periodontal surgery in combination with this kind of sutures.

Description:

A total of 60 patients will be included, where the unit of study will be each stitch, among the patients attending the Dental Clinic Service of the University of the Basque Country (UPV/EHU) who require surgical periodontal treatment. The patients will be randomly divided into two groups: the control group using a conventional suture (n=30), and the test group using a suture coated with chlorhexidine diacetate (n=30). Suture in the control group: absorbable suture of polyglactin 910 coated with polyglactin 370 + calcium stearate without chlorhexidine (NOVOSYN) Suture in the test group: absorbable suture of polyglactin 910 coated with polyglactin 370 + calcium stearate and chlorhexidine diacetate (NOVOSYN CHLORHEXIDINE) The primary variable in this study is post-surgical healing in both groups, which will be assessed using the healing index.

Intervention

Other:
• Periodontal Access Surgery+ Suture with chlorhexidine
Periodontal conventional surgery will be performed as treatment of periodontal diseases in patients who present active periodontal pockets. At the end of the surgery, the surgeon will suture the flap with the absorbable polyglactin 910 suture coated with chlorhexidine (Novosyn Chlorhexidine). Standardized post-surgical recommendations will be followed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Periodontal healing index (PQI) (Landry et al., 1988)	This periodontal healing index was described by Landy et al. in 1988. The index consists of the assessment of 5 clinical parameters (tissue color, bleeding on palpation, presence of granulation tissue, presence of suppuration, and healing of the surgical margin). The index will be from 1 to 5, where point 1 was defined as "healing way scarce" and point 5 such as "excellent healing" (Landry RG, Turnbull RS, Howley T. Effectiveness of benzydamine HCL in the treatment of periodontal post-surgical patients. Res Clin Forums. 1988; 10:105-118)	at 7 days, 14 days, 1 month and 2 months after surgery
Secondary	Pre-surgical pain	This variable will be collected by means of a questionnaire included in the pain diary (called "UPV/EHU pain diary" Fernández Jiménez et al., 2021).The examiner will record whether the subject has had any regional head and neck pain in the last month prior to the operation and whether any pain was present in the immediate pre-surgical period (last 24 hours). If so, its intensity will be recorded (visual analogue scale (from 0 to 10, where 0 represents no pain and 10 represents the maximum pain known to the subject.	The day of the surgical intervention
Secondary	Clinical level of central sensitization of the subject (Subclinical, Medium, Moderate, Severe and Extreme)	Prior to surgery a Central Sensitization Questionnaire (CSC) will be used (Cuesta-Vargas et al., 2016), in which each subject is asked about the frequency with which they perceive 25 symptoms and will be given a score of 0-4.; This will finally establish a clinical level in a range of 0-100 (Subclinical: 0-29 points; Medium: 30-39; Moderate: 40-49; Severe: 50-59; Extreme: 60-100).	Prior to surgery
Secondary	Post-surgical pain	The subject will be given a pain diary (PD) based on the VAS (Fernández-Jiménez et al., 2021) with instructions for its completion.; The subject will be instructed to record their perception of post-surgical pain at 2 and 4 hours, then every 8 hours for the first 3 days and finally daily at the end of the day for a week or until remission. Specifically, the subject will record three variables: the greatest intensity of the pain (0-100), its duration (minutes or hours) and whether any analgesic treatment has been necessary (No or Yes: Which one?). This information will be recorded until the pain has subsided	At 7 days after the surgery
Secondary	Achievement of primary closure after suturing (in the surgical act).	At each sutured site, the distance between the edges of the incision will be measured with a periodontal probe, being 0 the primary closure and from there we measure the mm of separation.	The day of the surgery
Secondary	Surgery location information (location of suture, surgery time, surgeon´s experience)	Location of the suture, indicating the teeth between which it is located, as well as the quadrant where it has been performed.; Surgery time: Minutes elapsed from the start of anesthesia to the knotting of the last stitch.; Surgeon's experience: number of previous periodontal surgeries performed by the surgeon and length of experience measured in months	The day of the surgery
Secondary	Post-surgical complications (PSCs)	The presence or not of any Post-surgical complications (PSCs) that may occur, as well as their description.	The day of the removal of sutures
Secondary	Presence of Visible plaque on the suture	Presence of Visible plaque on the suture (dichotomous: yes / no) on the day of stich removal, which will be assessed prior to their removal, noting the value in vestibular, palatal or lingual.	The day of the removal of sutures
Secondary	Suture looseness	It will be measured in mm with a calibrated periodontal probe, to the nearest 0.5 mm. Prior to cutting the suture, this will be grasped with stitch removal forceps, and the distance from the suture knot to the gingival tissue shall be measured.	The day of the removal of sutures
Secondary	Pain on suture removal	Pain on suture removal (dichotomous: yes/no) on suture removal, in which we will record whether or not the patient reports discomfort on suture removal.	The day of the removal of sutures
Secondary	Cytological-histological analysis	The suture of each patient will be analyzed by a) performing cytological smears (Papanicolaou stain) of the material deposited on the suture and b) histologically studying the knot (Included in 10% neutrally buffered formalin solution and later embedded in paraffin. Then, 8 µm thick sections were performed, which were stained with hematoxylin and eosin). Both analyses will be examined under an optical microscope.	The day of the removal of sutures
