The multispecies microbial cluster of Fusobacterium, Parvimonas, Bacteroides and Faecalibacterium as a precision biomarker for colorectal cancer diagnosis.

The incidence of colorectal cancer (CRC) has increased worldwide, and early diagnosis is crucial to reduce mortality rates. Therefore, new noninvasive biomarkers for CRC are required. Recent studies have revealed an imbalance in the oral and gut microbiomes of patients with CRC, as well as impaired gut vascular barrier function.

Parvimonas micra can translocate from the subgingival sulcus of the human oral cavity to colorectal adenocarcinoma.

Oral and intestinal samples from a cohort of 93 colorectal cancer (CRC) patients and 30 healthy controls (non-CRC) were collected for microbiome analysis. Saliva (28 non-CRC and 94 CRC), feces (30 non-CRC and 97 CRC), subgingival fluid (20 CRC), and tumor tissue samples (20 CRC) were used for 16S metabarcoding and/or RNA sequencing (RNAseq) approaches. A differential analysis of the abundance, performed with the ANCOM-BC package, adjusting the P-values by the Holm-Bonferroni method, revealed that Parvimonas was significantly over-represented in feces from CRC patients (P-value < 0.

Global DNA Methylation in Dental Implant Failure Due to Peri-Implantitis: An Exploratory Clinical Pilot Study.

Background: Peri-implantitis (PIT) is highly prevalent in patients with dental implants and is a challenging condition to treat due to the limited outcomes reported for non-surgical and surgical therapies. Therefore, epigenetic therapeutics might be of key importance to treat PIT. However, developing epigenetic therapeutics is based on understanding the relationship between epigenetics and disease.

Efficacy of growth factors for the treatment of peri-implant diseases: a systematic review and meta-analysis.

Objectives: The aim of this study was to conduct a systematic review and meta-analysis on the efficacy of growth factors (GF) on clinical outcomes after treatment (surgical/non-surgical) of peri-implant diseases (peri-implant mucositis and peri-implantitis).

Materials And Methods: A protocol was developed to answer the following focused question: Is there any difference for the use of GF for treatment of peri-implant diseases versus comparative GF treatment or without GF? Electronic database and manual searches were independently conducted to identify randomized controlled trials (RCTs). Publications were selected based on eligibility criteria and then assessed for risk-of-bias using the Cochrane Handbook.

Potentially malignant disorders of the oral cavity and oral dysplasia: A systematic review and meta-analysis of malignant transformation rate by subtype.

Importance: Potentially malignant disorders of the oral cavity (OPMD) are a heterogeneous group of lesions associated with a variable risk of malignant transformation (MT) to invasive cancer. Leukoplakia (LE), lichen planus (LP), oral lichenoid lesions (OLL), oral erythroplakia (OE), oral submucous fibrosis (OSF), and proliferative verrucous leukoplakia (PVL) are among the most common of these lesions. Oral dysplasia is a mucosal area characterized by cellular and architectural derangement, which may be associated with OPMDs or not.

Three-dimensional bone evaluation after surgical treatment with plasma rich in growth factors of Medication Related Osteonecrosis of the Jaw (MRONJ): A report of 3 cases.

Introduction: Medication Related Osteonecrosis of the Jaw (MRONJ) is an adverse effect of antiresorptive and antiangiogenic agents that consists of progressive bone destruction in the maxillofacial area. The purpose of this study is to analyze the effect on bone volume of a surgical protocol using plasma rich in growth factors (PRGF) for successfully treating MRONJ.

Methods: Three patients were treated combining surgical debridement with PRGF.

Locally advanced squamous cell carcinoma of the head and neck: A systematic review and Bayesian network meta-analysis of the currently available treatment options.

Background: There are still many unresolved questions in the management of locally advanced Head and Neck Cancer (HNC). Many chemotherapeutic drugs and radiotherapy fractionation schemes are available and not all have been evaluated in head-to-head clinical trials. This systematic review and Bayesian network meta-analysis aims to compare the available treatment strategies and chemotherapeutic options for locally advanced HNC.

Long-Term Implant Survival After 100 Maxillary Sinus Augmentations Using Plasma Rich in Growth Factors.

Purpose: To identify determinants of long-term implant survival after sinus augmentation procedure (SAP) using a combination of plasma rich in growth factors (PRGF) and graft material.

Materials And Methods: Patients were included in this retrospective study if they underwent SAP through a lateral wall approach using PRGF in combination with mainly xenograft, and received implants restored for at least 1 year. Sociodemographic, behavioral and implant characteristics (clinical factors, implant details, surgical details, prosthesis details, and complications) were analyzed.

Alveolar ridge preservation after tooth extraction: a Bayesian Network meta-analysis of grafting materials efficacy on prevention of bone height and width reduction.

Aims: To conduct a traditional meta-analysis and a Bayesian Network meta-analysis to synthesize the information coming from randomized controlled trials on different socket grafting materials and combine the resulting indirect evidence in order to make inferences on treatments that have not been compared directly.

Materials And Methods: RCTs were identified for inclusion in the systematic review and subsequent statistical analysis. Bone height and width remodelling were selected as the chosen summary measures for comparison.

Treatment of an Unusual Non-Tooth Related Enamel Pearl (EP) and 3 Teeth-Related EPs with Localized Periodontal Disease Without Teeth Extractions: A Case Report.

Enamel may be found ectopically as enamel pearls (EPs), which are frequently associated with advanced localized periodontal (LP) destruction. This study presents a case in which an unusual non-tooth-related enamel pearl and three teeth-related enamel pearls with LP disease were found and treated without teeth extractions. A 47-year-old female patient presented at the New York University College of Dentistry with four EPs, three of which were associated with periodontal pockets and/or bleeding on probing (BOP), and one of them not related to any tooth.

Histomorphometric Analysis of a Biopsy Harvested 10 Years After Maxillary Sinus Augmentation With Anorganic Bovine Bone Matrix and Plasma Rich in Growth Factors: A Case Report.

Purpose: To evaluate the histologic and histomorphometric data 10 years after grafting of maxillary sinus in a case using anorganic bovine bone matrix (ABBM) and plasma rich in growth factors (PRGF).

Materials And Methods: Histomorphometric measures were performed for newly formed bone, ABBM particles remnants, marrow spaces, and the presence of osteoblastic and osteoclastic activity.

Results: Histologic analysis showed ABBM particles surrounded by new compact and mature vital bone.
