    PSYCHOLOGICAL STRESS AND ORAL HEALTH: A COMPARISON OF POST-TRAUMATIC STRESS DISORDER, TOOTH WEAR, AND ORAL HYGIENE BETWEEN INDIVIDUALS WHO EXPERIENCED AND DID NOT EXPERIENCE AN EARTHQUAKE
    (Inonu University, 2026) Öcal, Fikri; Şimşek, Enis; Talmaç, Ayşe Gül Öner; Zayman, Esra Porgalı
    This study investigated the impact of a major natural disaster—the 2023 Türkiye earthquake— on post-traumatic stress disorder (PTSD), tooth wear, and oral hygiene by comparing affected individuals with those who did not experience the earthquake. A total of 504 participants were enrolled in a cross-sectional clinical study conducted at the İnönü University Faculty of Dentistry between June and July 2025. PTSD symptoms were assessed, and oral health evaluations included the Simplified Oral Hygiene Index (OHI-S) and Smith and Knight’s Tooth Wear Index. Results indicated significantly higher PTSD symptoms among individuals who experienced the earthquake, with PTSD prevalence of 43.03% in the exposed group, compared to 17.79% in the non-exposed group. Tooth wear scores were notably higher in participants with PTSD scores of 25 or above, suggesting a potential link between psychological stress and dental health. Oral hygiene was poorer in the earthquake-experienced group and was positively correlated with PTSD scores. Additionally, women exhibited higher PTSD scores and poorer oral hygiene than men, contrary to some previous findings. Younger individuals (<35 years) in the nonexposed group demonstrated better oral hygiene than those in other age groups. Despite these associations, the cross-sectional nature of the study limits causal interpretations. The findings emphasize the multifactorial relationship between psychological trauma and oral health, underlining the need for further longitudinal research to explore the long-term dental impacts of PTSD and disaster-related stress. © 2026 The Author(s).

    The Effect of Baking Soda and Vinegar on Tooth Wear
    (Ataturk Universitesi, 2025) Öcal, Fikri
    Alternative products used for tooth whitening teeth cause serious wear on tooth surfaces. Knowing the factors that cause tooth wear and their localizations plays an important role in reducing risk factors and treatment. In this case report, 2 patients who presented to the clinic with the complaint of tooth wear are presented. Case 1 used a mixture of vinegar and baking soda to whiten her teeth, while Case 2 used baking soda and whitening toothpaste. The wear on the tooth surface deepened in the cervical area. Both patients had horizontal tooth brushing and bruxism. Reduction of risk factors and direct composite restoration were described in the treatment. Alternative products that can be used to whiten teeth cause serious wear on teeth. Elimination of risk factors plays an important role in the treatment of these wear. The location and depth of the lesion play an important role in the treatment. © 2025, Ataturk Universitesi. All rights reserved.
