Gingival zenith level, position, and symmetry: A systematic review and meta-analysis.

Statement Of Problem: The gingival zenith (GZ) influences the line angle position in the emergence profile and the axial inclination of the crown. Irregularities in GZ symmetry and contour have a negative impact on dental esthetics. GZ location is not consistently distal to the crown's long axis; instead, it tends to be more distal in anterior teeth.

Do Recombinant, Purified, and Concentrated Growth Factors Enhance the Regenerative Potential of Particulate Bone Graft Substitutes in Maxillary Sinus Floor Augmentation? A Systematic Review and Meta-analysis.

Purpose: To answer the following question: 'Do recombinant, purified, and concentrated growth factors enhance the regenerative potential of particulate bone graft substitutes in maxillary sinus floor augmentation (MSA)?'

Materials And Methods: Human studies comparing histomorphometric data on new bone formation, residual graft material, and fibrous tissue ratio (outcomes of interest) following MSA procedures employing particulate bone grafts/substitutes in combination or not with growth factors were retrieved from PubMed/MEDLINE, Web of Science, Cochrane, and Scopus online databases and complemented with a hand search. Controlled studies published in English up to December 2022 and reporting on histomorphometric data expressed as volume percentage of the outcomes of interest were considered. Risk of bias was assessed, and a meta-analysis was performed to investigate the effects of supplementary growth factors on new bone formation, remaining graft particles, and fibrous tissue ratio.

Evaluation of Alveolar Bone Dimensions and Root Positioning of Anterior Teeth in the Maxilla.

Buccal bone walls present significant resorption after tooth extraction, possibly related to the smaller bone thickness, length, and the sagittal position of the root, as well as the bone morphology. The goal of the present study was to measure the thickness of the cortical bone of the vestibular and palatal walls in the anterior maxilla by means of CBCT images. Measurements were taken from CBCT scans of 300 maxillary anterior teeth from 50 patients (25 women, 25 men) aged 18 to 30 years.

Single-stage advanced versus rotated flaps in the treatment of gingival recessions: A 5-year longitudinal randomized clinical trial.

Background: The objective of the present study was to compare the efficacy of single-stage laterally positioned flap (LPF) and coronally advanced flap (CAF) techniques in the treatment of localized maxillary gingival recession (GR) defects, 1 and 5 years after surgical procedures.

Methods: Thirty-six patients with Miller Class I GR defects were randomly assigned to be treated by either CAF (n = 18) or LPF (n = 18). Recession height (RECH), width of keratinized tissue (WKT), probing depth (PD), vertical clinical attachment level (VAL), visual plaque score (VPS), and bleeding on probing (BOP) were assessed and compared.

The relationship between open versus normal contact point and inter-proximal papilla dimensions in periodontally healthy young adults: A controlled clinical trial.

Aim: The gingival architecture is determined by the spatial orientation of the gingival zenith (GZ) and the inter-dental papillae (IP). Among the factors commonly associated with the presence and morphology of the IP, the contact point (CP) and the inter-dental distance relationships have been considered the most important. The objective of the present controlled clinical trial was to evaluate the role of the CP in determining the clinical and morphometric parameters of the inter-dental papilla.

Human intrabony defect regeneration with rhFGF-2 and hyaluronic acid - a randomized controlled clinical trial.

Aim: The goal of this study was to evaluate if a biological hydrogel of recombinant human Fibroblast Growth Factor type 2 (rhFGF-2) in a hyaluronic acid (HA) carrier applied in periodontal intrabony defects would enhance the clinical parameters of regeneration of the periodontal attachment apparatus

Materials And Methods: Thirty adult patients were evaluated. Two intrabony defects present in contra-lateral quadrants in each patient were randomly allocated for each of the treatment methods employed. Control group (n = 30) were treated by open debridement with the papilla preservation flaps, while the test group (n = 30) also received a topical application of rhFGF-2/HA in the intrabony defect.
