The aim of the present study was to evaluate the effect of short fiber reinforced composite on the fracture strength of anterior immature teeth treated with regenerative endodontic procedures. A total of 120 permanent maxillary central incisors were selected, and root lengths were standardized. Except for the positive control group (n = 20), the root canals were instrumented to simulate immature teeth with incomplete root development, and the regenerative endodontic procedure was performed. Twenty instrumented teeth acted as negative controls (n = 20), and the remaining 80 teeth were randomly divided into 4 groups according to the chosen coronal restoration material: bulk fill, short fiber reinforced composite (SFRC), polyethylene fiber (Ribbond Ultra), and flowable composite resin. Each specimen was then subjected to fracture testing using a universal testing machine (AGS-X, Shimadzu, Japan). The load to fracture was recorded. Data were subjected to statistical analysis using analysis of variance and the Tukey Honestly Significant Difference test. A significant difference was detected between the groups (p < 0.05), with the positive control group showing the highest mean fracture strength. The SFRC group had significantly higher values than the bulk fill, polyethylene fiber, flowable composite resin and negative control groups. In conclusion, SFRC has a relatively high fracture strength compared to other materials used in regenerative endodontic procedures. The use of SFRC enhanced the fracture strength of immature permanent teeth.

This study aimed to evaluate oral and dental health status, hygiene practices, and access to dental care among adults living in Gaza, Khan Younis, and the central governorates of Palestine. A descriptive cross-sectional survey was conducted in 2025 among 39 adults aged ≥18 years residing in the study regions. Data were collected using a structured questionnaire (14 closed-ended and 4 open-ended questions) addressing oral hygiene habits, healthcare access, living conditions, and perceptions of dental services. The survey was administered via Google Forms. Descriptive statistics were used, and categorical variables were presented as frequencies and percentages. The study included 39 participants (48.7% women, 51.3% men). None reported adequate access to nutritious food. A high proportion (89.7%) experienced toothache within the last two years. The most common response was self-management with analgesics (71.6%), while other strategies included visiting a health facility (28.6%), tooth extraction (28.6%), and use of traditional remedies (28.6%). A small proportion (5.7%) reported taking no action. Only 46.2% had visited a dentist in the last two years. Open-ended responses highlighted key challenges, including lack of hygiene supplies (25.6%), limited access to dental services (20.5%), financial constraints (5.1%), poor nutrition (5.1%), and ongoing oral health problems (5.1%). Findings indicate a substantial burden of untreated oral conditions and limited access to dental care in a conflict-affected population. Oral health needs should be integrated into humanitarian health responses to ensure access to preventive and essential dental services.

Aim: The aim of this study is to evaluate the relationship between endocrine disruptor chemicals using in the daily routine during breastfeeding and pregnancy period and the developmental enamel defects (DDE) and Molar Incisor Hypomineralization (MIH) presence. Method: 313 (n=313) parents and their child who aged between 8 and 11, along with their parents, were enrolled in the study for routine dental check-ups at the pediatric dentistry clinic was included to this current study. This is a descriptional and cross-sectional study. Prior to participant enrolment, this study was approved by the Hamidiye Scientific Ethical Research Committee, University of Health Sciences (22-591). After consent forms were completed, the surveys' questions were scanned via QR codes on patients' phones for them to answer. The dental examination of the child was conducted, and the condition of the teeth was documented based on enamel defects. The relationship between categorical variables obtained from oral findings was examined through chi-square analysis, with analyses conducted using SPSS 20.0 software at a 95% confidence interval. Results: MIH prevalence was 36 % ( n=114) and DDE prevalence was 3% ( n=10). 4% (n=15) of the population have defects on lower incisor teeth. There is a significant relationship between the consumption of packaged foods during the breastfeeding period and the MIH group (p < 0.05). Also, it was observed that there is a statistically significant association between drug usage during pregnancy and the occurrence of MIH and DDE. Conclusion: The likelihood of developmental enamel defects and Molar-Incisor Hypomineralization (MIH) has been associated with the consumption of packaged foods during pregnancy and lactation. Further comprehensive studies are needed regarding the use of endocrine-disrupting chemicals.
