Article Synopsis
  • The study investigates tooth agenesis (TA) patterns in individuals with Down syndrome (DS) to inform treatment planning and understand underlying causes.
  • A secondary analysis of six studies involving 241 individuals with DS was conducted, revealing 86 distinct Overall-TAC patterns for TA, with the most common types being bilateral maxillary lateral incisor and mandibular second premolar agenesis.
  • Results indicate that nearly half of the cases showed symmetry in TA patterns, and the absence of both mandibular central incisors is a strong predictor for oligodontia in these individuals.

Background: Toothbrushing, limiting intake frequency, and scheduled visits to an oral healthcare professional (OHP) are key for good oral health. We aimed to explore factors influencing these oral health behaviours in Dutch adolescents with mild to borderline intellectual disabilities (MBID) in residential care.

Method: Using a qualitative, descriptive approach, we conducted focus groups and interviews with 12 adolescents, 9 counsellors, and 6 OHPs.

Aims: The aim of this systematic review is to compare the effectiveness of a powered (PTB) and a manual (MTB) toothbrush in the hands of people with physical (PD) or intellectual (ID) disabilities or in the hands of a caregiver on parameters of plaque and gingival inflammation.

Methods: MEDLINE-PubMed, Cochrane-CENTRAL and EMBASE databases were searched from initiation up to February 2022. The inclusion criteria were clinical trials conducted in people with PDs or IDs and comparing the effect of toothbrushing with a PTB to an MTB on plaque removal and gingival health.

Aim: Retrospective analysis of subgingival microbiological data at intake in relation to the clinical periodontal status at intake and following non-surgical periodontal treatment.

Materials And Methods: Data were obtained from a population that consisted of patients diagnosed with moderate-to-severe periodontitis who had undergone non-surgical periodontal treatment between 2016 and 2020. The presence and number of eight selected putative periodontal pathogens [Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Prevotella intermedia (Pi), Tannerella forsythia (Tf), Parvimonas micra (Pm), Fusobacterium nucleatum (Fn), Treponema denticola (Td) and Filifactor alocis (Fa)] at intake and the percentage of teeth and sites with PPD >5 mm at intake and after treatment were extracted.

Objective: This retrospective analysis aimed to evaluate, among individuals with COVID-19-like symptoms, the percentage of SARS-CoV-2 positive oral health care workers relative to health care workers in general and a non-close-contact occupation reference group in the Netherlands.

Materials And Methods: Data was retrospectively analyzed based on data extracted from the CoronIT database. This contained mass testing data for those experiencing symptoms compatible with COVID-19 recorded from June 2020 up to February 2021.
