Periodontal furcation lesions: a survey of diagnosis and management by general dental practitioners
(2021)
Aim: The aim of this study was to explore general dental practitioners' (GDPs) attitude to periodontal furcation involvement (FI). Materials and methods: An online survey focused on diagnosis and management of periodontal FI was circulated to GDPs in seven different countries. Results: A total of 400 responses were collected. Nearly a fifth of participants reported rarely or never taking 6-point pocket charts; 65.8% of participants had access to a Nabers probe in their practice. When shown clinical pictures and radiographs of FI-involved molars, the majority of participants correctly diagnosed it. Although 47.1% of participants were very/extremely confident in detecting FI, only 8.9% felt very/extremely confident at treating it. Differences in responses were detected according to country and year of qualification, with a trend towards less interest in periodontal diagnosis and treatment in younger generations. Lack of knowledge of management/referral pathways (reported by 22.8%) and lack of correct equipment were considered the biggest barriers to FI management. Most participants (80.9%) were interested in learning more about FI, ideally face to face followed by online tutorials. Conclusions: Plans should be put in place to improve general dentists' knowledge and ability to manage FI, as this can have a significant impact on public health.
Aim: Assessment of the effect of nonsurgical periodontal therapy on haematological parameters in patients with grades B (BP) and C periodontitis (CP).
Methods: Eight BP and 46 CP patients received full-mouth periodontal debridement within 48 h, if positive for Aggregatibacter actinomycetemcomitans with adjunctive systemic antibiotics (4 BP, 17 CP). Clinical data were collected prior and 12 weeks after periodontal therapy. Blood was sampled prior to and 1 day as well as 6 and 12 weeks after the first SD visit. Erythrocyte count, haemoglobin value, haematocrit (HCT), mean erythrocyte volume (MCV), mean corpuscular haemoglobin (MCH), MCH concentration (MCHC), platelets (PLT) and heat shock protein 27 (Hsp27) were assessed.
Results: Both groups showed significant clinical improvement (p < 0.05). Using univariate analysis, MCV was noticeably lower in CP than BP at all examinations, HCT only at baseline. For CP, MCHC was noticeably higher 12 weeks after SD than at baseline and 1 day (p ≤ 0.005) and Hsp27 increased noticeably at 1 day (p < 0.05). Repeated measures analysis of variance revealed African origin to be associated with lower MCV and female sex with lower MCHC.
Conclusion: Based on multivariate analysis, periodontal diagnosis (BP/CP) was not associated with haematological parameters measured in this study or serum Hsp27. In CP, nonsurgical periodontal therapy improved MCHC 12 weeks after SD. Also in CP Hsp27 was increased 1 day after SD.
