    Aims: The gender and age distribution of temporomandibular disorder (TMD) suggest a possible role for the female hormonal axis in the pathogenesis. The goal of this study was to evaluate if estrogen receptor (ESR1) gene variants contribute to TMD susceptibility in the Turkish population. Methods: A total of 270 people, 130 of whom were TMD patients and 140 healthy controls, were included in the study. The ESR1 PvuII (rs2234693) and Xbal (rs9340799) variants were genotyped using the polymerase chain reaction based restriction fragment length polymorphism (PCR-RFLP). The results were evaluated statistically. Results: There were 110 women (81.48%) and 25 men (18.52%) in the patient group. We found there was a significant association between rs2234693 T/C, C/C genotypes and TMD (p=0.007). Also, the C allele was more prevalent in patients compared to controls (p=0.002). A statistically significant association was observed when the patients were compared with the controls according to TT versus TC+CC (p=0.002). There was no statistical significance between the patient and control groups in terms of rs9340799 genotype and allele distribution. Then we evaluated the relationship between genotype distributions and clinical characteristics. Both males and females had the highest rs2234693 T/C genotype (p=0.049). The majority of people with bruxism, bruxomania, and bruxism plus bruxoma carried the rs2234693 T/C genotype (p=0.025). Conclusions: Our results showed that ESR1 rs2234693 might be associated with TMD risk in the Turkish population, but not rs9340799.

    The Relationship Between Odontogenic Cyst and P53 Codon 72 And P53 Codon 175 Variants in Turkish Patients
    (2023) Tumer, Mehmet Kemal; Keskin, Adem; Aci, Recai; Yigit, Serbulent
    Objective: Odontogenic cysts that cause bone destruction can exhibit various types of metaplasia. Inherited genetic variants in codons 72 and 175, the hotspot codons of p53, known as the guardian of the genome, can cause a wide variety of cancers. We aimed to investigate the effects of the p53 codon 72 and p53 codon 175 variants on odontogenic cyst formation. Methods: This research encompassed 71 individuals with odontogenic cysts and 90 without any conditions as a control group. After DNA was extracting, the p53 codon 72 was detected using PCR techniques, while p53 codon 175 was identified through allele-specific amplification-PCR. Results: The presence of the p53 codon 72 GG genotype and its G allele was less frequent in the group with odontogenic cysts compared to the healthy participants. Conversely, the C allele was found more often in the cyst-afflicted group. For the p53 codon 175, the AA genotype and A allele were more common in the affected group, while the G allele was more predominant in the control group. Conclusion: The p53 codon 175 AA genotype and A allele, p53 codon 72 C allele, and p53 codon 72/codon 175 CCAA combined genotype may be associated with odontagenic cyst formation. Individuals with this allele and genotype can be considered at risk for odontagenic cyst formation.
