Brief Summary

Objectives: This study aimed to determine the effect of concomitant antimicrobial photodynamic therapy (aPTD) on periodontal disease and glycaemic control in patients with type 2 diabetes mellitus (T2DM). Clinical Relevance: aPTD is a noninvasive adjunctive therapy that can positively influence the periodontal treatment outcome.

Outcome Measures

Primary Outcomes (10)

  • Probing pocket depth (PPD)

    Probing pocket depth measured using manual probe at 6 sites around each tooth. Unit: millimeters

    At baseline

  • Probing pocket depth (PPD)

    Probing pocket depth measured using manual probe at 6 sites around each tooth. Unit: millimeters

    90 days after treatment

  • Bleeding on probing (BOP)

    Yes/No after probing pocket depth measurement 6 sites around each tooth. Unit: % (bleeding sites/all sites)

    At baseline

  • Bleeding on probing (BOP)

    Yes/No after probing pocket depth measurement 6 sites around each tooth. Unit: % (bleeding sites/all sites)

    90 days after treatment

  • Clinical attachment level (CAL)

    This is the measurement of the position of the soft tissue attachment in relation to the cemento-enamel junction (CEJ). Two measurements are used to calculate the CAL: the probing depth and the distance from the gingival margin to the CEJ. Unit: millimeters

    At baseline

  • Clinical attachment level (CAL)

    This is the measurement of the position of the soft tissue attachment in relation to the cemento-enamel junction (CEJ). Two measurements are used to calculate the CAL: the probing depth and the distance from the gingival margin to the CEJ. Unit: millimeters

    90 days after treatment

  • The presence of five periodontal pathogens, Aggregatibacter actinomycetemcomitans (AA), Porphyromonas gingivalis (PG), Prevotella intermedia (PI), Tanerella forsythia (TF) and Treponema denticola (TD),

    Plaque samples were collected with sterile paper tips after supragingival soft and hard debris had been removed according to the manufacturer's instructions. Analysis by Polymerase chain reaction (PCR) followed by hybridization against species-specific DNA probes. According to the manufacturer, the cut-off of the test is set at 10³ to 10⁴ genome equivalents

Study Arms (2)

Control Arm

OTHER

Conventional Periodontal Treatment: Complete Oral Disinfection.

Procedure: Conventional Periodontal Treatment (Complete Oral Disinfection)

Experimental Arm

EXPERIMENTAL

Conventional Periodontal Treatment (Complete Oral Disinfection) and Adjunctive Photodynamic Therapy in periodontal pockets with PPD ≥ 5 mm.

Procedure: Conventional Periodontal Treatment (Complete Oral Disinfection)Procedure: Adjunctive Photodynamic Therapy

Interventions

Oral hygiene instructions followed by complete oral disinfection (removal of hard and soft deposits, scaling and root planing, mouth rinse with 0.2% chlorhexidine twice in one minute, pocket rinse with 0.2% chlorhexidine three times in ten minutes). Ultrasonic (Piezoled, KaVo) and hand instruments (Gracey curettes, Hu-Friedy, USA) were used for this purpose. For the next 14 days, all patients were asked to rinse their oral cavities twice daily with 0.12% chlorhexidine.

Control ArmExperimental Arm

Photodynamic Therapy as adjunctive treatment in pockets with PPD ≥ 5 mm. For this purpose, a Fotona XD -2 diode laser (Fotona, Ljubljana, Slovenia) with a wavelength of 810 nm, a power of 250 mW and the photosensitizing agent indocyanine green at a concentration of 1 mg/ml was used. First, the area to be irradiated was isolated, and the photosensitizing agent was applied to the periodontal pocket. After 60 seconds, the supragingival excess of the photosensitizing agent was removed by gentle rinsing with a saline solution. This was followed by irradiation for ten seconds on each side. For the next 14 days, all patients were asked to rinse their oral cavities twice daily with 0.12% chlorhexidine.

Model Details: Test and Control group. All patients received oral hygiene instructions followed by complete oral disinfection (removal of hard and soft deposits, scaling and root planing, mouth rinse with 0.2% chlorhexidine twice in one minute, pocket rinse with 0.2% chlorhexidine three times in ten minutes). Ultrasonic (Piezoled, KaVo) and hand instruments (Gracey curettes, Hu-Friedy, USA) were used for this purpose. Afterwards, the patients were randomly divided into test and control groups. The patients in the test group received aPDT as adjuvant treatment in pockets with PPD ≥ 5 mm.
