Radiographic morphology of intrabony defects in the first molars of patients with localized aggressive periodontitis: Comparison with health and chronic periodontitis

Abstract

First molars of patients with LAgP affected by intrabony defects may have some distinct radiographic anatomical characteristics to those of healthy subjects. The shape of intrabony defects seems to differ between LAgP and chronic periodontitis cases. Further studies need to confirm these features and investigate if they are related to the initiation and progression of periodontitis.

The importance of supportive periodontal therapy for molars treated with furcation tunnelling

“…Molars treated with tunnelling included in this study had lost approximately a third to half of the supporting bone at first visit and had lost around a third of the bone apical to the furcation entrance. A trend for association with tooth loss was noted for vertical furcation involvement, particularly class B (strangely none of the six class C‐diagnosed molars at baseline were lost during the follow‐up period), in line with evidence from previous studies (Nibali, Tomlins, et al, ; Tonetti et al, ).…”

“…It has been established that furcation involvement, specifically degree II and III, increases the risk of tooth loss, even in patients undergoing regular SPT (Nibali et al, 2016). The risk seems to increase by both horizontal (Nibali, Krajewski, et al, 2017b;Nibali et al, 2016) and vertical furcation degree (Nibali, Tomlins, & Akcalı, 2018a;Tonetti, Christiansen, & Cortellini, 2017). However, approximately 60% of degree III furcation-involved molars included in longitudinal studies survived at least 10 years (Nibali et al, 2016).…”

Three periodontitis phenotypes: Bone loss patterns, antibiotic—surgical treatment and the new classification

“…pattern of bone loss (Nibali, Tomlins, & Akcali, 2018) which presumably was identified by the clinicians in this study.…”

“…If the immune fitness is dysregulated, the resultant aberrant host response leads to a destructive periodontal inflammation that further induces a microbial dysbiosis and the latter heightens back the aberrant response in a vicious cycle (Loos & Van Dyke, 2020). The younger age and the absence of smoking in the cluster A leads to the hypothesis that the major parameter playing a role in the dysregulated immune fitness for these patients could be the presence of specific (epi)genetic factors (Shaddox et al., 2017) which provide a favourable ecosystem for certain pathobionts (such as Aa ) into the dysbiotic biofilm (Nibali, 2015); the phenotypic result of this process is the localized pattern of bone loss (Nibali, Tomlins, & Akcali, 2018) which presumably was identified by the clinicians in this study.…”

A 16-year-old boy with chronic discharging sinus on upper left lateral incisor tooth

“…Mofazzal Hossain (MS Resident): This asymptomatic condition usually diagnosed by routine radiographic examination. [7][8] In this case, the tooth is symptomatic with history of swelling and presence of an apical discharging sinus, it disfavors the diagnosis as chronic apical periodontitis.…”
