    An assessment of periodontal health in patients with schizophrenia and taking antipsychotic medication
    (Wiley-Blackwell, 2013) Eltas, A.; Kartalci, S.; Eltas, S. D.; Dundar, S.; Uslu, M. O.
    Background and objective: Severe periodontal disease is prevalent among patients with schizophrenia and is caused by the side effect of their medication, poor dental hygiene and smoking. The objective of this study was to evaluate whether the rate of periodontal disease could be modulated by changing the salivary flow rate (SFR) because of the use of antipsychotic medications in patients with schizophrenia. Methods: Group A (n=33) included patients who used medications that may cause xerostomia, or dry mouth and Group B (n=20) included patients who used medications that may cause sialorrhea, an excessive secretion of saliva. The participants' periodontal status was assessed using the plaque index (PI), assessing bleeding on probing (BoP), probing pocket depth (PPD) and clinical attachment levels (CAL). Results: The mean of PI and BoP was significantly higher in Group A than in Group B (P<0.001), but the PPD, CAL and decayed, missing and filled teeth (DMFT) scores were not significantly different in the two groups according to the statistical results (0.05). Conclusions: The researcher concluded that there is a high risk of periodontal disease among patients with schizophrenia, and there is an even higher risk of periodontal disease induced by medication that increased SFR. Preventive dental protocol should be increased during the dental health care of this disadvantaged patient group.

    Does osseointegration occur around nonprimary stabilized titanium implants? A histomorphometric analysis
    (Ariesdue Srl, 2023) Toy, V. E.; Sabanci, A. C.; Dundar, S.; Bozoglan, A.
    Aim The aim of this study was to analyze the levels of bone implant contact (BIC) and bone area between the threads (BABT) of primary and nonprimary stabilized titanium implants histologically in rats. Materials and methods Fourteen Sprague-Dawley rats were categorized as two groups: primary (PS) and nonprimary stabilization (NPS) groups. Totally, 14 titanium implants with machined surfaces were integrated into the tibial bones of the rats with and without primary stabilization in the PS and NPS groups, respectively. After 12 weeks of healing, the rats were sacrificed, block sections were acquired for histological analysis. Results The BIC ratios (%) in the PS and NPS groups were 53.23 +/- 5.65% and 40.79 +/- 5.59%, respectively and was significantly higher in the PS group as compared with that in the NPS group (P<0.05). The mean BABT ratios (%) in the PS and NPS groups were 55.71 +/- 7.32% and 37.14 +/- 2.67% respectively. The BABT ratio (%) was significantly higher in the PS group than in the NPS group (P<0.05). Conclusion The results suggest that osseointegration may occur despite the absence of primary stability at the end of a 12-week healing period but primary stabilization at the time of installation appears to be critical in achieving maximum BIC and BABT.
