AI Article Synopsis
- The study investigates the link between gingival recession and buccal bone deficiencies in maxillary anterior teeth, using clinical and radiographic data from 66 adult subjects.
- Findings reveal that gingival recession is common, particularly in canines, and is significantly associated with reduced buccal bone thickness and increased distance between the bone crest and the cemento-enamel junction (CEJ).
- Gingival recession serves as a strong predictor for buccal bone thickness under 1 mm, with factors like probing depth and patient demographics influencing both conditions.
Article Abstract
Background: Gingival recession and a thin or absent buccal plate occur frequently at maxillary anterior teeth and necessitate careful treatment planning to prevent future complications. However, the association between these two conditions is unclear and the ability of gingival recession to predict underlying buccal bone deficiencies is unknown. Therefore, the aim of this study is to use clinical and radiographic data to test this association and determine the influence of demographic and clinical parameters on both conditions.
Methods: This investigation comprised a single-center, retrospective study. Data were derived from periodontal examinations performed on 66 adult subjects. Corresponding cone-beam computed tomography images were used to measure the width of buccal bone at two points along the root surface and the distance between the bone crest and cemento-enamel junction (CEJ). Results were then analyzed to determine the association between the presence of gingival recession and the condition of radiographic buccal bone, as well as the relative contribution of demographic parameters and other clinical findings to gingival recession and buccal bone conditions.
Results: Gingival recession was present at 32.9% of maxillary anterior teeth and was most common at canines, followed by lateral incisors and central incisors. Mean buccal bone widths were significantly less, and the distance between the CEJ and bone crest was significantly greater for teeth with recession. Accordingly, gingival recession was a significant predictor for buccal bone thickness <1 mm at the level of 4 mm apical to the CEJ (odds ratio 2.733, 95% confidence interval 1.644 to 4.543, P < 0.0001). Probing depths were related to the presence or absence of gingival recession, while patient sex, age, and the apico-coronal height of the gingiva were related to buccal bone thickness.
Conclusion: Within the limitations of this study, maxillary anterior teeth with pre-existing gingival recession were more likely to have thin (<1 mm) buccal bone.

Objective: To compare the influence of different emergence profile of implants in mandibular molar on the peri-implant soft tissue.
Methods: Forty-four implants were divided into two equal groups by mucosal thickness, ≥2 mm (group A) or < 2 mm (group B), and were randomly included in the test group and the control group. In the control group, the patients were treated by a prosthesis with no transmucosal modifications (subgroups A1 and B1).

Orthodontic treatment aims to correct malocclusions and ensure the overall health and stability of the periodontium. The relationship between orthodontic therapy and periodontal health is intricate and multifaceted, and a comprehensive approach is often required to achieve optimal outcomes. Firstly, this article delves into the impact of orthodontic mechanics on periodontal tissues, emphasizing the importance of minimizing iatrogenic effects such as root resorption and gingival recession.

Insufficient keratinized mucosa is a common clinical problem. Although there is no consistent data on the long-term success of implant restorations relative to the presence or absence of peri-implant keratinized mucosa, it is widely accepted that the presence of keratinized mucosa width<2 mm is associated with increased biofilm accumulation, soft-tissue inflammation, and mucosal recession. Free gingival graft (FGG) is the standard surgical intervention for augmenting the width of keratinized gingiva.

Background: Injectable platelet-rich fibrin (i-PRF) has the capacity to release great amounts of several growth factors, as well as to stimulate increased fibroblast migration and the expression of collagen, transforming growth factor β, and platelet-derived growth factor. Consequently, i-PRF can be used as a bioactive agent to promote periodontal tissue regeneration.
Objective: We aim to compare and evaluate the effectiveness of i-PRF in periodontal tissue regeneration.
