Summary
Peri-implantitis affects nearly one in five patients and one in ten implants over four years. Key risk factors include severe periodontitis, smoking, and specific implant restoration types.
Area of Science:
- Dental Implantology
- Periodontology
- Prosthodontics
Background:
- Peri-implantitis is a significant complication following dental implant placement.
- Understanding its incidence and risk factors is crucial for long-term implant success.
Purpose of the Study:
- To determine the incidence of peri-implantitis in a prospective cohort.
- To identify risk and protective factors associated with peri-implantitis development over time.
Main Methods:
- A cohort of 73 patients with 322 implants was followed for a mean of 3.9 years.
- Peri-implantitis was defined by bleeding on probing and bone loss >1mm.
- Multilevel logistic regression analyzed baseline risk factors.
Main Results:
- The incidence of peri-implantitis was 22.2% in patients and 9.4% in implants.
- Significant risk factors included severe periodontitis (Stage IV), smoking, longer sleep duration (>7h), incisor location, full-arch restorations, and juxta-marginal restoration margins.
- Keratinized tissue width was not associated with peri-implantitis.
Conclusions:
- Nearly 20% of patients and 10% of implants developed peri-implantitis within four years.
- Periodontitis severity, lifestyle factors (smoking, sleep), implant location, and prosthetic characteristics are key risk factors.
- These findings aid in predicting and potentially preventing peri-implantitis.

Overview
01:20Mismatch Repair
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
