ÖZET
 Son yıllardaki metagenomik çalışmalar, adli vaka çözümlerinde etkili olabilen mikrobiyal genetik araştırmaları, adli bilimlerin kullanımına sunmaktadır. Bu çalışmalar içerisinde, insanların vücut alanını paylaşan kommensal, simbiyotik ve patojenik mikroorganizmaların ekolojik topluluğu olarak belirtilen mikrobiyomların DNA araştırmaları büyük bir yer tutmaktadır. Adli soruşturmalarda tükürük, bulunabilirlik kolaylığı ve noninvaziv olması nedeniyle tüm vücut sıvıları arasında sıklıkla tercih edilir. DNA teknolojisindeki ilerlemeler, şüphesiz ki insan DNA'sının, ısırık izlerinden ve dudak izlerinden elde edilen tükürük lekelerinden bile izolasyonunu sağlamaktadır. Fakat toplanan örneklerin degrade olması veya az miktarda DNA bulunması gibi sebeplerle her zaman kalitesi uygun bir tükürük DNA'sı elde edilemeyebilir. Oysa tükürüğün adli araştırmalarında, tükürük salgısındaki mikrobiyomların (bakteriler, mantarlar, arkeler, mikrobiyal ökaryotlar ve virüsler) analizinden elde edilen bilgiler, olayın failini suçla ilişkilendirebilir. Nitekim insan DNA'sı, şüphelinin gündelik temasından tespit edilemese de mikrobiyom profili tespit edilebilir ve bu da şüphelinin spesifik mikrobiyom profili aracılığıyla tanımlanması olasılığını artırır. Ayrıca şüphelinin yaşam tarzı, birlikte yaşadığı kişiler ve tıbbi durum bilgileri, adli soruşturmalara yardımcı olabilir. Mikrobiyom verilerinin, adli amaçlı kanıt olarak kullanımı ve rutin prosedür hâline gelebilmesi için insan mikrobiyom araştırmalarının adli bakış açısı ile ele alınması gerekir. Bu yazıda, adli alandaki yeni tükürük mikrobiyomu araştırmalarının mevcut durumu, geliştirilen analiz metotları, değerlendirmelerde kullanılan biyoinformatik çözümler ve oral mikrobiyotanın, adli bilimlerde kullanımındaki olası sınırlandırmalar ve uygulamadaki zorluklar hakkında bilgi paylaşımı amaçlanmıştır.

ABSTRACT
 Metagenomic studies in recent years offer microbial genetic studies that can be effective in forensic case solutions to the use of forensic sciences. Among these studies, DNA research of microbiomes, which is defined as an ecological community of commensal, symbiotic and pathogenic microorganisms that share human body space, has a great place. In forensic investigations, saliva is often preferred among all body fluids due to its ease of availability and non-invasiveness. Advances in DNA technology enable the isolation of human DNA, even from saliva stains obtained from bite and lip prints. However, it is not always possible to obtain a salivary DNA of appropriate quality due to the degradability of the samples or the small DNA amount. Whereas, in saliva forensic studies, information obtained from the analysis of salivary microbiomes (bacteria, fungi, archaea, microbial eukaryotes, and viruses) may associate the perpetrator with crime. Indeed, although human DNA cannot be detected from daily contact with the suspect, the microbiome profile can be detected, increasing the likelihood that the suspect will be identified through the specific microbiome profile. Also, information such as the suspect's lifestyle, cohabitants, and medical condition can assist with forensic investigations. In order for microbiome data to be used as forensic evidence and become a routine procedure, human microbiome studies should be handled with a forensic perspective. In this article, it is aimed to share information about the current status of new salivary microbiome research in the forensic field, developed analysis methods, bioinformatics solutions used in evaluations, possible limitations in the use of oral microbiota in forensic sciences and difficulties in application.
