SummaryAim: The aim of the study was to evaluate the impact of oral health education and non-surgical periodontal therapy on the quality of life for a group of patients with type I diabetes mellitus, in Iasi, Romania.Materials and Method: The study was conducted on 21 patients with type 1 diabetes mellitus which also presented a form of periodontitis. We examined: the degree of glycaemic control (by measuring the glycated haemoglobin), the periodontal and oral hygiene parameters at the baseline and after 4 weeks, 6 months and 12 months after the periodontal treatment which consisted in scaling and root planing. The patients also filled an OHIP-14 questionnaire at baseline and 6 month after the periodontal therapy to assess the quality of life.Results and Discussion: We observed a rapid recurrence of the deep periodontal pockets after 12 months in subjects with poor glycaemic control. At baseline, the highest scores for the OHIP-14 were in the sub-domains of pain, discomfort on chewing and self-consciousness.Conclusions: The prolonged poor control of glycaemia is closely related with its complications. The periodontal therapy improved (lower values) the domain codes and final score of the OHIP-14 questionnaire, proving that periodontal health has an impact on the diabetic patients’ quality of life.
Orthodontic treatment in patients with no periodontal tissue breakdown vs. horizontal bone loss should be approached with caution even though it can bring significant benefits in terms of periodontal recovery and long-term success. We used the finite element method (FEM) to simulate various clinical scenarios regarding the periodontal involvement: healthy with no horizontal bone loss, moderate periodontal damage (33%) and severe horizontal bone loss (66%). Afterwards, forces of different magnitudes (0.25 N, 1 N, 3 N, and 5 N) were applied in order to observe the behavioral patterns. Through mathematical modeling, we recorded the maximum equivalent stresses (σ ech), the stresses on the direction of force application (σ c) and the displacements produced (f) in the whole tooth–periodontal ligament–alveolar bone complex with various degrees of periodontal damage. The magnitude of lingualization forces in the lower anterior teeth influences primarily the values of equivalent tension, then those of the tensions in the direction in which the force is applied, and lastly those of the displacement of the lower central incisor. However, in the case of the lower lateral incisor, it influences primarily the values of the tensions in the direction in which the force is applied, then those of equivalent tensions, and lastly those of displacement. Anatomical particularities should also be considered since they may contribute to increased periodontal risk in case of lingualization of the LLI compared to that of the LCI, with a potential emergence of the “wedge effect”. To minimize periodontal hazards, the orthodontic force applied on anterior teeth with affected periodontium should not exceed 1 N.
The aim of this study was to investigate the effects of adjunctive periodontal therapy of 5 mg/mL indocyanine green irradiation by an 810 nm diode laser (aPDT), supplementary to scaling and root planing (SRP) in patients with periodontitis and type II diabetes mellitus (DM) compared to the SRP alone, on periodontal clinical parameters and glycated hemoglobin A1c (HbA1c). The study was conducted on 49 subjects with type II DM and periodontitis, divided into two groups: the SRP group (n = 25), who followed SRP alone, and the SRP + aPDT group (n = 24), who followed SRP and four weekly sessions of indocyanine green irradiation by an 810 nm diode laser. Plaque Index (PI), Bleeding on Probing Index (BOP), probing depth (PD), clinical attachment loss (CAL) and HbA1c were investigated at baseline and after 6 months. At 6 months, both SRP alone and SRP + aPDT generated significant reductions in all the investigated parameters; SRP + aPDT produced more significant reductions for BOP, PD and CAL (p < 0.001) but not for PI and HbA1c, than SRP alone. aPDT with indocyanine green therapy was well tolerated, with two subjects reporting slight discomfort. Therefore, aPDT with indocyanine green might represent a good adjunctive periodontal treatment option for SRP in patients with type II DM and periodontitis.
The relationship between periodontitis and systemic diseases is an important part of clinical periodontal research, which has been growing steadily. Even though the etiologies of periodontal disease and rheumatoid arthritis (RA) differ, these pathologies have many common features, both being multifactorial diseases characterized by localized chronic inflammatory reactions, which are fuelled by an analogous set of cytokines (among many, the most prominent being Tumour Necrosis Factor (TNF), Interleukin (IL) 6 and 17), leading to high systemic circulating concentrations of inflammatory markers such as C-reactive protein (CRP). It was not until the discovery of peptidylarginine deiminase (PAD) mediated citrullination of proteins by Porphyromonas gingivalis that the link between the two diseases was purely speculative. This citrullination initiates a series of events which culminate in the production of anti-citrullinated protein antibodies (ACPA) and, finally, in the clinical manifestation of rheumatoid arthritis. Another common denominator is the bone destruction caused by proinflammatory cytokines secreted by T 17 helper cells (TH17) which is the pathological hallmark of both diseases. Other notable common areas are shared risk factors such as environmental and genetic risk factors. Regarding treatment, neither pathologies have a definitive cure, however, several strategies are employed, some of which are common, such as diet and lifestyle changes, and immunomodulating medication applied locally or systemically.
