Unlabelled: Peri-implant bone loss leading to dental implant failure does not develop in the same way across subjects who apparently present the same condition-specifically, in the case of Down syndrome patients with the same genetic disorder-given that they do not necessarily develop immune-inflammatory disorders to the same extent.

Methods: This retrospective case-control study was aimed at identifying the possible genes involved in implant failure in Down syndrome patients by matching the periodontal disease variable by means of a retrospective case-control study. This process involved using the functional analysis of gene expression software Transcriptome Analysis Console (TAC, Affymetrix, Thermo Fisher Scientific, Waltham, MA, USA) and a search for the possible candidate genes involved.

Article Synopsis
  • The study aimed to investigate inflammation-related gene expression differences in Down Syndrome patients with periodontal disease (DS+PD+) versus those without (DS+PD-), highlighting impaired immunity in these patients.
  • Researchers conducted a case-control study with eleven Down Syndrome patients, extracting RNA from their blood to analyze the expression levels of 92 selected inflammation-related genes using advanced genetic analysis tools.
  • Results revealed that four specific genes (TNFSF13B, ITGB2, ANXA3, and ANXA5) showed significant differences in expression between the two groups, indicating a link between chronic oral inflammation and gene expression in Down Syndrome patients.

Background: Sometimes dental implants seem to be the only therapeutic alternative for the oral rehabilitation of patients with Down syndrome, given that they usually lose all their teeth early due to suffering aggressive periodontitis and they do not usually have the skills required to wear removable prostheses. However, the evolution of dental implants in these patients shows very adverse results. It is possible that basal genetic alterations, or at least some characteristics of these, may underlie these clinical results.

Statement Of Problem: The need for tooth replacement in individuals with Down syndrome (DS) is explained by the high prevalence of dental agenesis and by the premature loss of teeth through severe periodontal disease. Dental implants may be the dental procedure of choice in some of these patients.

Purpose: The purpose of this clinical study was to analyze dental implant survival in a series of patients with DS.

Dental treatment on Handicapped Patients is often difficult because many people with a wide range of ages (from children to the elderly) with different pathologies that can affect the oral cavity and differ widely are included in this group. This situation creates some controversy, because according to pathology, each patient will be treated differently depending on collaboration, general health status, age or medication used to treat this pathologies. According to this situation we can opt for an outpatient treatment without any kind of previous medication, a treatment under conscious or deep sedation or a under general anesthesia treatment.
