This study evaluated the effects of a single-stage full mouth disinfection (FMD) protocol versus a quadrant-based tooth surface cleaning and root planing (Q-SRP) protocol on changes in clinical periodontal parameters over a 3-month period, as well as on the social, psychological and functional well-being of patients with poorly controlled type 2 diabetes and severe periodontitis.
In this study, Q-SRP was administered to one group of patients with uncontrolled diabetes and severe periodontitis, whilst the TAD protocol was implemented in the other group. All clinical procedures were carried out in accordance with standard protocols. Post-treatment assessments were carried out at the 1-month and 3-month follow-up periods; all clinical periodontal measurements recorded at baseline, along with the OHIP-14 and OIDP questionnaires, were repeated in the same manner. This enabled a comparative analysis of the efficacy of the treatment methods applied and the clinical changes over time.

| Quality of life questionnaires | The impact of periodontal treatments on patients' quality of life was investigated by administering the OHIP-14 and OIDP questionnaires at baseline, one month post-treatment, and three months post-treatment. Responses obtained from participants via the OHIP-14 questionnaire were assessed using a five-point Likert scale for each item. The scale was scored as follows: 0 (never), 1 (rarely), 2 (occasionally), 3 (often) and 4 (very often). The total oral health-related quality of life score for each individual was calculated by summing the scores given for each question. | Before treatment, 1 and 3 months after treatment |

| Percentage of Deep (≥ 7 mm) Probed Pockets | During measurements taken using a Williams periodontal probe (Hu Friedy, Chicago, Illinois, USA), the probe was positioned parallel to the long axis of the teeth without applying pressure, and the distance from the gingival margin to the base of the periodontal pocket was measured and recorded. The percentage of pocket depths of 7 mm or more, measured from the six regions of each tooth (mesiobuccal, buccal, distobuccal, mesiolingual, lingual and distolingual), was calculated relative to the total number of tooth surfaces measured in the mouth. The percentage of all pocket depths of 7 mm or more in the individual's mouth was calculated using the following formula. % ≥ 7 mm PD = Total of pocket depths of 7 mm or more × 100 / Total number of teeth × 6 |

| full mouth disinfeciton | Procedure | Full Mouth Disinfection involves scaling and root planing all teeth within 24 hours, often paired with intensive antiseptics to prevent re-infection from remaining pockets |

| Percentage of Pockets Detected at Medium Depth (4-6 mm) | During measurements taken using a Williams periodontal probe (Hu Friedy, Chicago, Illinois, USA), the probe was positioned parallel to the long axis of the teeth without applying pressure, and the distance from the gingival margin to the base of the periodontal pocket was measured and recorded. The percentage of pocket depths within the 4-6 mm range, measured from six regions of each tooth (mesiobuccal, buccal, distobuccal, mesiolingual, lingual and distolingual), was calculated relative to the total number of tooth surfaces measured in the mouth. The percentage of pocket depths within the 4-6 mm range for the entire mouth was calculated using the following formula. %4-6 mm PD = (Total of 4-6 mm pocket depths × 100) / (Total number of teeth × 6) | Before treatment, month after treatment and 3 months after treatment |
| Clinical Attachment Level | The distance from the enamel-cementum junction to the sulcus/pocket floor was measured in millimetres on six surfaces of the tooth-mesiobuccal, buccal, distobuccal, mesiolingual, lingual and distolingual-using a Williams periodontal probe (Williams periodontal probe, Hu Friedy, Chicago, IL, USA). The average CAL value for the entire mouth was calculated using the following formula: CAL = Sum of clinical attachment levels / Number of existing teeth × 6 | Before treatment, month after treatment and 3 months after treatment |
| Probed Pocket Depth | Pocket depth was measured in six regions: mesiobuccal, buccal, distobuccal, mesiolingual, lingual and distolingual. A Williams periodontal probe was used for the measurements (Hu Friedy, Chicago, Illinois, USA). During the measurements, the periodontal probe was positioned parallel to the long axis of the teeth without applying pressure, and the distance from the gingival margin to the base of the periodontal pocket was measured and recorded. The following formula was used to determine the average PD for the individual's entire mouth. PD = Sum of probed pocket depths / Number of existing teeth × 6 | Before treatment, month after treatment and 3 months after treatment |
| Bleeding on Probing | When the periodontal probe was gently moved along the gingival sulcus, a score of (+) was assigned if bleeding occurred, and (-) if no bleeding occurred. The final score was calculated as a percentage (%). Bleeding Score (%) = Number of teeth with bleeding × 100 / Total number of teeth | Before treatment, month after treatment and 3 months after treatment |
| Plaque Index | The Silness-Löe plaque index (PI) was used to measure the degree of plaque formation and accumulation in the mouth. According to this index: 0 = No bacterial plaque in the gingival region,
The individual's PI score was calculated using the following formula after summing the PI scores obtained from the mesiobuccal, buccal, distobuccal and lingual surfaces of each tooth. PI = Total of PI scores for all teeth / Number of teeth present × 4 | Before treatment, month after treatment and 3 months after treatment |
| Gingival Index | The Löe-Silness gingival index (GI) was used to diagnose gingival inflammation. According to this classification: 0=Healthy gums
The individual's GI score was calculated using the following formula after summing the GI scores obtained from the mesiobuccal, buccal, distobuccal and lingual surfaces of each tooth. GI = Total of GI scores for all teeth / Number of existing teeth × 4 | Before treatment, month after treatment and 3 months after treatment |
