Brazilian Institute of Geography and Statistics (IBGE) data indicate that the elderly population of Brazil numbering 11% in 2003, will attain 33.7% by 2060. This aging process can be diagnosed from the capability workers possess for their labor activities. ProKnow-C was used to conduct the review, carrying out bibliometric and systemic analysis of the literature on the subject. The results led to the compilation of a portfolio with 29 papers, highlighting the most relevant journals, authors and keywords. Systemic analysis provided important results: survey methodology was applied on 26 papers, 21 of which were cross-sectional studies; in all the papers the WAI was associated with sociodemographic data; in 10 studies it was found that the work ability decreased while age increased and the practice of physical exercises was positively associated with the WAI in 11 studies. The results led to the perception that the WAI is an instrument that makes it possible to diagnose the situation of the working life of employees, and, in the case of low rates, the presence of early functional aging is detected. The study highlighted the importance of assessing aspects of the worker’s social life, since these factors influence the work ability positively or negatively.

Temporomandibular disorder (TMD) is an umbrella term used to describe various conditions that affect temporomandibular joints, masticatory muscles, and associated structures. Although the most conservative and least invasive treatment is preferable, more invasive therapies should be employed to refractory patients. Tissue engineering has been presented as a promising therapy. Our study aimed to investigate trends and point out future research directions on TMD and stem cells. A comprehensive search was carried out in the Web of Science Core Collection (WoS-CC) in October 2022. The bibliometric parameters were analyzed through descriptive statistics and graphical mapping. Thus, 125 papers, published between 1992 and 2022 in 65 journals, were selected. The period with the highest number of publications and citations was between 2012 and 2022. China has produced the most publications on the subject. The most frequently used keywords were “cartilage”, “temporomandibular joint”, “mesenchymal stem cells”, and “osteoarthritis”. Moreover, the primary type of study was in vivo. It was noticed that using stem cells to improve temporomandibular joint repair and regeneration is a significant subject of investigation. Nonetheless, a greater understanding of the biological interaction and the benefits of using these cells in patients with TMD is required.

This review article mapped and analyzed the most cited articles on the association of photobiomodulation (PBM) with oral mucositis (OM) and the evolution of clinical protocols in the area. A comprehensive search was performed on the Web of Science Core Collection (WoS-CC) database, leading to the extraction of information such as title, authors, abstract, journal name, number, average of citations, study design, year of publication, institutions, continents, countries, type of laser used, irradiated anatomical points, primary anti-cancer therapy, and laser parameters. Among those, clinical trials and literature reviews were the most common study designs. The main type of laser used was the InGaAlP diode, with a wavelength ranging from 630-660 nm, power going in 40-100 mW, and energy density ranging from 0.375-22 J/cm(2). As for the anatomical sites irradiated by PBM, the cheek mucosa, upper and lower lips, lateral tongue, and bottom of the mouth stood out. This analysis highlights an increasing interest in PBM as a supportive treatment in cases of OM, as well as the evolution of the technique, types of laser devices, and protocols used.
