Background:
Oral infectious diseases, such as dental caries, periodontitis and periapical periodontitis, are often complicated by causative bacterial biofilm formation and significantly impact human oral health and quality of life. Bacteriophage (phage) therapy has emerged as a potential alternative with successful applications in antimicrobial trials. While therapeutic use of phages has been considered as effective treatment of some infectious diseases, related research focusing on oral infectious diseases is few and lacks attention. Therefore, a systematic review was conducted to comprehensively evaluate the overall efficacy of phages in reducing bacterial infections associated with various oral diseases.
Methods:
A systematic search of PubMed, MEDLINE and Web of Science for literature published up to May 2024 was conducted according to inclusion criteria to identify studies assessing bacteriophages as potential therapy for oral infectious diseases. A total of four authors assessed study eligibility and performed data extraction.
Results:
A total of 487 articles published between 1975 and 2024 were retrieved. Among the 10 eligible reports, preliminary studies have been conducted on seven types of phages and reported their antibacterial effect. To be more specific, 3 contained data on dental caries (n = 32), 5 focused on periodontitis (n = 105) and 2 examined periapical diseases (n = 7). The majority of publications (9 out of 10) discussed the impact of phages on biofilm formation. Only one report (1 out of 10) mentioned the safety concern in phage application.
Conclusions:
This review strongly suggests that phages isolated from oral cavity with certain characteristics can be highly effective and are considered suitable candidates for phage therapy in treating oral/odontogenic infections caused by bacteria.

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
