Domains, competences and learning outcomes for undergraduate education in periodontology.

Aim: This review is intended to adapt the current conceptual framework in dental education based on four domains to propose a set of competences, learning outcomes and methods of teaching, learning and assessment for undergraduate education in periodontology.

Review: Based on the current framework of competences and learning outcomes recommended by the Association for Dental Education in Europe (ADEE), undergraduate education in periodontology has been updated using the classification and clinical practice guidelines for the diagnosis and treatment of periodontal and peri-implant diseases.

Conclusions: Specific learning outcomes have been proposed within each competence area, that is in Domain I (n = 10), Domain II (n = 13), Domain III (n = 33) and Domain IV (n = 12).

New putative periodontopathogens and periodontal health-associated species: A systematic review and meta-analysis.

To investigate the existence of any association between new putative periodontal pathogens and periodontitis. Two independent reviewers conducted electronic literature searches in the MEDLINE (PubMed), EMBASE, DOSS and Google Scholar databases as well as a manual search to identify eligible clinical studies prior to November 2022. Studies comparing the prevalence of microorganisms other than the already-known periodontal pathogens in subgingival plaque and/or saliva samples between subjects with periodontitis and subject with periodontal health were included.

Correlation of Redondovirus and Detections in the Human Oral Cavity Suggests That This Amoeba Is Possibly the Redondovirus Host.

The virome of the human oral cavity and the relationships between viruses and diseases such as periodontitis are scarcely deciphered. Redondoviruses were reported in the human oral cavity in 2019, including in periodontitis patients. Here, we aimed at detecting redondoviruses and at searching for a potential viral host in human saliva.

Microscopic observations of SARS-CoV-2 like particles in different oral samples.

The emerging coronavirus pneumonia epidemic caused by the SARS-CoV-2 infection has spread rapidly around the world. The main routes of transmission of SARS-CoV-2 are currently recognised as aerosol/droplet inhalation. However, the involvement of the oral cavity in coronavirus disease 2019 (COVID-19) is poorly known.

Materials And Methods: Two independent reviewers conducted electronic literature searches in MEDLINE (PubMed), EMBASE, Cochrane Library, Web Of Science, Dentistry & Oral Sciences Source, ScienceDirect, and ClinicalTrials.gov databases as well as a manual search to identify eligible clinical studies from January 2000 to March 2022.

Smile Aesthetic Evaluation on Videographs: An Intra-Rater and Inter-Rater Agreement Study.

The aim of this study was to assess on videographs the intra- and inter-rater reproducibility of the Smile Esthetic Index (SEI) that has been previously validated on photographs. Smile videographs were obtained using a smartphone associated with the Smile Lite MDP mounted on a tripod. They were then randomized and evaluated twice consecutively at a 1-week interval by three periodontists according to the SEI based on 10 variables.

Isolation and characterization of sp. nov., a novel species detected in a gingivitis subject.

A Gram-negative bacterium, designated strain Marseille-Q3452, was isolated from subgingival dental plaque of a subject suffering from dental plaque biofilm-induced gingivitis on an intact periodontium in Marseille, France. The strain was characterized by 16S rRNA and gene sequence analysis and by conventional phenotypic and chemotaxonomic testing. The average nucleotide identity (ANI) and core genome phylogeny were determined using whole-genome sequences.

A Gram-stain-negative bacterium, designated strain Marseille-Q3039, was isolated from subgingival dental plaque of a woman with gingivitis in Marseille, France. Strain Marseille-Q3039 was found to be an anaerobic, motile and spore-forming crescent-shaped bacterium that grew at 25-41.5 °C (optimum, 37 °C), pH 5.

Isolation and Characterization of sp. nov., a Novel Species Detected in a Gingivitis Subject.

species are commensal gliding bacteria that are found in human and animal oral microbiota and are involved in several inflammatory diseases, both in immunocompromised and immunocompetent subjects. This study contributes to increased knowledge of this genus by characterizing a novel species isolated from a dental plaque sample in a male with gingivitis. We investigated morphological and chemotaxonomic characteristics using different growth conditions, temperature, and pH.

Isolation and Description of sp. nov., a Novel Species, Isolated from a Stable Periodontitis Subject.

The genus currently counts a unique species, , isolated from periodontal pockets and associated with periodontitis and endodontic infections. This study contributed to the taxonomical and clinical knowledge of this genus by describing a novel species isolated from a saliva sample from a man in clinical gingival health following successful treatment of periodontitis. Morphological and chemotaxonomic characteristics were investigated using different growth conditions, pH, and temperature.

Isolation and Characterization of sp. nov., A Novel Species Detected in a Stable Periodontitis Subject.

Members of the genus are mostly commensals of the oral cavity, but some of them are involved in invasive infections, especially in young children. This study provides new knowledge on the diversity of this genus by describing a novel species of isolated from a dental plaque sample from a 51-year-old man with a history of periodontitis. Morphological and chemotaxonomic characteristic were investigated using different growth conditions, pH and temperature.

Rapid diagnosis of periodontitis, a feasibility study using MALDI-TOF mass spectrometry.

Aim: The aim of the present study was to assess the feasibility and diagnostic contribution of protein profiling using MALDI-TOF mass spectrometry applied to saliva, gingival crevicular fluid (GCF) and dental plaque from periodontitis and healthy subjects. We hypothesized that rapid routine and blinded MALDI-TOF analysis could accurately classify these three types of samples according to periodontal state.

Materials And Methods: Unstimulated saliva, GCF and dental plaque, collected from periodontitis subjects and healthy controls, were analyzed by MALDI-TOF MS.

Perioperative management of oral anticoagulated patients undergoing an oral, implant, or periodontal procedure: a survey of practices of members of two dental scientific societies, the PRADICO study.

Objectives: Studies on the perioperative management of patients on direct oral anticoagulants (DOACs) receiving oral invasive procedures are sparse. Moreover, the recommendations of the scientific societies on DOACs are discordant, and the practices are highly variable. We conducted a survey of general and specialized dentists in France to compare their practices concerning the management of patients receiving vitamin K antagonists (VKAs) and DOACs.

[Oral and periodontal hygiene in orthodontic patients].

Introduction: Orthodontic appliances promote dental plaque retention and make tooth-brushing less easy. They result in both quantitative and qualitative changes in dental plaque, exposing orthodontic patients to dental caries and periodontal diseases.

Materials And Methods: The authors explain the effects of orthodontic treatments on dental plaque and the occurrence of dental and periodontal problems; they emphasize the role of pathogenic bacteria and highlight the need for efficient (both individual and professional) control of dental plaque.

[Perfecting smile esthetics: keep it pink!].

Introduction: Smile aesthetics is based on numerical, physical, physiological and psychological data regarding beauty, while taking into account the desires of the patient. It is determined by the shape, colour and position of the lips, teeth and gingival tissues. Periodontal examination in both the facial and labial settings supports analysis of the gingival display during natural and forced smiling, the health of the periodontium, the gingival contours, the aesthetic gingival line, and the presence of the papillae.

[Behavior of the periodontium during leveling of the mandibular incisors: what precautions are needed?].

Since the position of the mandibular incisors is one of the keys to successful treatment, most orthodontic treatments focus on control but take no special precautions regarding the periodontal environment. Can we trust the lateral headfilm alone when evaluating such slender quantities of bone surrounding the mandibular incisors? What is the true bone situation prior to treatment and above all, following alignment, leveling and uprighting of the incisors? We performed a prospective 3-year study on 50 patients to assess the periodontal behavior of the mandibular incisors following a leveling phase by means of a clinical approach using periodontal and radiologic probing based on measurements of bone thickness obtained by cone beam. The bone loss observed was not inconsiderable given the thinness of the initial bone.

[Reason for failure in the treatment of impacted and retained teeth].

The positioning of an impacted or retained tooth in either children or adults presents a real challenge for the two practitioners involved, the orthodontist and the surgeon in charge of the surgical exposure. The maxillary canine is the tooth most often impacted in the anterior segment, with a prevalence of 2% in the general population. One can understand, therefore, the functional and esthetic challenge for the surgical-orthodontic team whose aim will be to reposition the impacted or retained tooth in the arch.

[Reciprocal relationships between orthodontics and periodontics in esthetic treatments].

The objective of this article is to review various unsightly periodontal defects and the treatments that have previously been used to eliminate them in order to establish guidelines for future therapy. The inter-relationship between orthodontic and periodontal disciplines is well established and needs no defense here. Periodontal tissues change throughout life and the same is true for the smile.

Do membrane undulations help cells probe the world?

Cells sense physical properties of their environment including substratum rigidity, roughness, and topography of recognition sites. The cell surface displays continuous deformations of nanometer-scale amplitude and Hz frequency. Recent results support the hypothesis that these surface undulations constitute a powerful strategy for the rapid acquisition of environmental cues: transient contact with surroundings generates forces of piconewton intensity as a result of rapid formation and dissociation of intermolecular bonds.

Qualitative cosmetic evaluation after root-coverage procedures.

Background: The purpose of the present study was to evaluate the esthetic outcome using four categories of root-coverage procedures (pedicle soft tissue grafts, non-submerged grafts, submerged grafts, and envelope techniques) and to identify factors associated with esthetic assessment.

Methods: A professional panel of three observers (two periodontists and one control) used a before-after panel scoring system to evaluate the esthetics of 162 root-coverage surgeries. A five-point ordinal scale was used to evaluate the overall esthetic improvement and seven variables that may be considered in the assessment.

Gingival contour assessment: clinical parameters useful for esthetic diagnosis and treatment.

Background: The purposes of this study were to quantify some clinical parameters that are useful as esthetic guidelines when the gingival contour is modified and to compare the left and right sides of the six maxillary anterior teeth.

Methods: Maxillary casts mounted on an articulator according to the axis orbital plane were photographed from 103 young adults. The angle formed between the gingival line and the maxillary midline (GLA) and the distance between the gingival zenith of the lateral incisor and the gingival line (LID) were measured.

A retrospective study of root coverage procedures using an image analysis system.

Aim: To investigate the efficacy of root coverage procedures and factors that may affect the clinical outcomes in non-experimental patients.

Material And Methods: Two hundred and eighty-seven root coverage surgical procedures in 215 adult patients were evaluated retrospectively. Descriptive statistics were used to determine the patient profile.

Root coverage assessment: validity and reproducibility of an image analysis system.

Aim: The aim of this methodological study was to validate a new method for root coverage evaluation following periodontal plastic surgery.

Material And Methods: Thirty recessions were treated in 21 consecutive patients, using a subepithelial connective tissue graft technique. Clinical measurements and photographs were taken at baseline and 12+/-6 months after treatment.

Connective tissue graft for gingival recession treatment: assessment of the maximum graft dimensions at the palatal vault as a donor site.

Background: The palatal masticatory mucosa is widely used as a connective tissue donor site in gingival recession treatment. However, concern has been raised regarding the potential risk of damaging the greater palatine artery (GPA) due to anatomical variations in the palatal vault. The anatomy of the palatal vault in terms of size and shape may affect the maximum dimensions of the graft that can be safely taken from the palatal vault.
