AI Article Synopsis
- The study examined the saliva of elderly individuals in long-term care facilities to understand how factors like tooth loss and denture use affect biochemical and microbiological properties.
- Researchers collected saliva samples from 161 participants and conducted oral examinations to assess the presence of biofilm, missing teeth, and denture use.
- Findings indicated that edentulism and denture use did not significantly affect saliva's protein levels or microorganism counts, but the presence of biofilm on dentures was linked to specific bacteria in the saliva.
Article Abstract
Background: To analyze biochemical and microbiological parameters of the saliva of institutionalized elders and to investigate the relation of these parameters with edentulism, use of dentures and presence of biofilm.
Material And Methods: A cross-sectional study carried was out in seven long-term institutions. Samples (n=161) of unstimulated saliva were collected for analysis of salivary flow, quantification of total proteins and identification of microorganisms. Oral examination was carried out to verify the number of missing teeth, the use of dentures and the presence of visible biofilm on the surface of teeth and dentures. Associations were performed using chi-square or Fisher's exact test (α<0.05). Mann-Whitney Test was used to identify differences in the salivary flow and total proteins (α<0.05).
Results: There was no association between the type of edentulism and use of dentures with biochemical and microbiological parameters of saliva (>0.05). Associations were observed between the presence of dentures biofilm and the colonization of sp. (=0.038) and sp. (=0.03).
Conclusions: The absence of teeth and use of dentures do not influence the amount of total proteins and the microorganisms count in saliva. Denture biofilms are associated with the presence of sp. and sp. in saliva of institutionalized elders. Candida, long-stay institutions for elders, saliva, Streptococcus, Staphylococcus.

Article Synopsis
- The study examined 444 residents over 18 in Mongolia's Khangai region to assess dentition defects and the need for orthopedic treatment.
- Dentition defects were found in 91.3% of participants, with a noticeable increase in defects as age rose, particularly in those aged 45 to 74.
- Most participants with defects (49.0%) lacked dentures, highlighting a significant need for prosthetics due to economic and lifestyle factors affecting oral health in the region.

Background: Edentulism impacts the physical health and quality of life of older individuals. The prevalence, influencing factors, and differences in terms of edentulism in urban and rural areas of China are unclear.
Objective: This study investigated the denture-wearing conditions and causes affecting older patients with edentulism in urban and rural areas of China and analyzed the differences.

Ingested foreign bodies, although fairly common among children, can present in individuals of all age. Most common risk factors for such cases in adults include psychiatric illness, alcohol abuse and ill-fitting dentures. Most of the ingested foreign bodies pass through the gastrointestinal tract but intervention maybe required in case of impaction, obstruction or perforation.

Background: Oral health is recognized as integral to general health and impaired dentition status may affect physical performance among older adults. This study evaluated the longitudinal association between clinical and self-reported oral health measures and physical performance (outcome) in Brazilian older adults.
Methods: This was a longitudinal study that used data from the second (year 2006), third (year 2010) and fourth (year 2015) waves of the Health Well-being and Aging Study conducted in Brazil.

Purpose: This systematic review (SR) aimed to investigate whether the presence of a cantilever affects the results of implant treatment for partial edentulism, including an analysis of the anterior and posterior regions of the dental arches.
Methods: An electronic search was performed, and original articles published between 1995 and November 2023 were included. The outcomes were the implant survival rate, patient satisfaction, occurrence of mechanical complications, and marginal bone loss around the implants.
