Abstract

Latar Belakang: COVID-19 merupakan penyakit menular dengan tingkat penularan tinggi, sehingga diagnosis cepat dan akurat sangat penting untuk mengendalikan penyebaran. Saliva memiliki potensi sebagai alternatif diagnostik non-invasif untuk mendeteksi SARS-CoV-2. Metode: Penelitian ini menggunakan studi literatur sistematis terhadap publikasi tahun 2020–2025 dari PubMed, Scopus, dan Google Scholar yang membahas penggunaan saliva sebagai spesimen diagnostik COVID-19. Hasil: Kajian menunjukkan sensitivitas dan spesifisitas saliva sebanding dengan spesimen nasofaring, dengan tingkat kesesuaian diagnosis lebih dari 90%. Saliva dinilai praktis, hemat biaya, serta dapat mengurangi risiko penularan kepada tenaga medis. Namun, terdapat potensi false negatif atau positif pada fase awal penyakit yang perlu diperhatikan. Kesimpulan: Saliva memiliki keunggulan sebagai cairan diagnostik COVID-19 yang efektif, aman, dan nyaman, serta berpotensi digunakan secara luas untuk skrining dan pemantauan penyakit.

Abstract

Alveolar osteitis (dry socket) is a common complication after tooth extraction that delays bone healing and causes significant pain. Conventional treatments are largely palliative and do not actively promote regeneration. Salivary exosomes, rich in bioactive molecules, and chitosan, a biocompatible and biodegradable polymer, might offer a promising combined approach for targeted bone regeneration. The aim of this systematic review was to systematically evaluate the regenerative potential of salivary exosomes encapsulated in chitosan for the treatment of alveolar osteitis. The systematic review was conducted following PRISMA guidelines and the PICO framework. Comprehensive searches were performed across PubMed, ScienceDirect, ProQuest, Cochrane Library, and Google Scholar for English-language articles published between 2021 and 2025. Eligible studies included in vitro, in vivo, and preclinical research assessing chitosan-encapsulated salivary exosomes for bone regeneration. Data were extracted on study design, interventions, outcome measures, and therapeutic effects. From 524 retrieved records, 10 full-text articles were assessed, and two met the eligibility criteria. Both studies demonstrated that chitosan encapsulation improved the stability and delivery efficiency of salivary exosomes. Outcomes included increased osteogenic gene expression (ALP, BMP-2, osteocalcin, RUNX2), enhanced angiogenesis, reduced inflammation, and histological evidence of accelerated bone regeneration compared with conventional treatment. In conclusion, current evidence suggests that salivary exosomes encapsulated in chitosan have strong therapeutic potential for alveolar osteitis by promoting osteogenesis, reducing inflammation, and enhancing bone healing. However, further preclinical validation and controlled human trials are required before clinical translation.

Abstract

Background: Biofilms are involved in a wide variety of microbial infections, including dental caries and periodontitis. The use of probiotics has been a promising prevention and treatment modality with which to combat biofilm-related diseases in the oral cavity. The probiotic Lactobacillus reuteri has been proven to reduce gingivitis and plaque index inside the oral cavity. These bacteria can be found in the digestive system and also in the human oral cavity. Objective: The aim of this study was to identify L. reuteri in the saliva of Indonesian young adults. Methods: Forty saliva samples were collected from 18–24 year-old Indonesian subjects. DNA extraction was performed, and then, the identification of L. reuteri was accomplished using PCR. Six subjects showed positive results. The positive samples were cultured in Rogosa Agar for 24 hours at 37°C anaerobically. Several single colonies were further cultured separately in broth medium before DNA extraction and PCR identification were performed. The four thickest bands were selected for DNA sequencing. Results: An analysis performed using BLAST showed that two of the L. reuteri strains obtained from the Indonesian saliva isolates had 96% (isolate 3.11) and 95% (isolate 5.14) values. This confirmed the presence of new strains based on average nucleotide identity (ANI). The isolate strains of 3.11 and 5.14 have been registered at DDBJ/EMBL/GenBank under the accession number LC382415 and LC382416, respectively. Conclusion: L. reuteri novel strain can be isolated from the saliva of Indonesian young adults.  Further studies involving biochemical tests and phenotypic analysis are needed to better understand these new L. reuteri strains.

Abstract

Primary Sjogren syndrome (pSS) is a chronic autoimmune disorder affecting the exocrine function of the eyes and mouth. Dryness of the mouth and the underlying inflammatory condition may cause alteration of the oral microbiota and connective tissue integrity which may ultimately lead to periodontal disease, such as periodontitis. Studies have shown varying result regarding the association of periodontitis in patients with pSS. This study aims to assess the risk of developing periodontitis in patients with pSS. Literature search was conducted on PubMed, ProQuest, EBSCOHost, and Cochrane databases, with studies evaluating the risk of developing periodontitis in patients with pSS from inception to December 2023 being selected. The Newcastle-Ottawa scale was used in this study to assess the perceived risk of bias of the included studies. This review included one retrospective study and two cross-sectional studies involving 773 patients with pSS. The prevalence of periodontitis in pSS patients is 479 patients (61.9%). Inconsistency of statistical significance is found in regards of relative risk of developing periodontitis. Patients with pSS has an increased relative risk of developing periodontitis. Inconsistency of statistical significance was found between studies.

Abstract

Periodontitis is a persistent inflammatory condition caused by a buildup of oral bacteria that damages the tissues around the teeth. It is defined by the deterioration of these tissues, which can result in tooth loss if not treated. The extent of periodontitis is influenced by various factors, including the host's immune response to bacteria that cause periodontal disease. Periodontal infections induce the differentiation of CD4+ T cells into various subsets, including Th1, Th2, Th17, Tregs, and other subsets. This review aimed to determine if there is an association between different subsets of CD4+ T cells and the severity of periodontitis. The research conducted a scoping review, which utilized the scoping review method to systematically map and analyze the literature results on the subject issue. The article search method employed Scopus, PubMed, and ScienceDirect databases, and a manual search was also conducted using keywords and the Boolean Operators technique. The publications were chosen based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Review (PRISMA-ScR) flow, following the established criteria for inclusion and exclusion. As a result, 11 relevant publications were gathered and subsequently examined, focusing on the CD4+ T cell subsets in individuals with periodontitis. The publications show that individuals with periodontitis display a more prominent expression of subgroups of T cells. Moreover, the severity of periodontitis is strongly influenced by the host's immune response, particularly the balance between proinflammatory and anti-inflammatory CD4+ T cell subsets.
