Achieving reliable implant stability in type IV (D4) bone remains a clinical challenge due to its thin cortical plates and low trabecular density, which increase the risk of early failure. Novel osteotomy techniques such as osseodensification and the OsseoShaper have been proposed, yet their effects when combined with different implant macrogeometries are not fully understood. This in vitro study evaluated forty osteotomies in standardized polyurethane foam blocks simulating D4 bone density. Three site preparation protocols—conventional osteotomy, osseodensification, and OsseoShaper—were combined with two implant macrogeometries (parallel-walled conical and tri-oval tapered designs). Insertion torque (IT) was measured using a calibrated digital torque meter, and implant stability was assessed by resonance frequency analysis (ISQ). Intraoperative thermal changes were monitored with infrared thermography under constant irrigation. Statistically significant differences were observed among groups (p < 0.05). Osseodensification with parallel-walled implants achieved the highest stability, whereas osseodensification with tri-oval implants showed the lowest. Although osseodensification produced the greatest thermal increase, all values remained below the 47 °C osteonecrosis threshold. Within the study’s limitations, both the osteotomy technique and implant macrogeometry significantly affected stability and thermal outcomes, with osseodensification plus parallel-walled implants providing the most predictable performance in D4 bone.

Purpose: Local anesthetic agents have been widely used in dentistry for several decades. Administration of local anesthetics at body temperature has been reported to shorten the onset time and reduce pain during injection. The aim of this study was to compare the effect of the local anesthetic at body temperature and room temperature before wisdom tooth extraction in terms of injection pain and onset of anesthesia.Materials and Methods: Forty-six adult patients, who were undergoing wisdom tooth extraction, participated in this split-mouth study. To the one side of the patient’s jaws warmed anesthetic solution and to the other side anesthetic solution at room temperature was injected.Results: There was no statistically significant difference between two groups. Mean onset time of anesthesia and VAS scores during injection were similar for room temperature and warmed anesthetic solution groups. None of the patients exhibited any complications during and after injection.Conclusion: Further studies, which include large number of samples, may indicate the effectiveness of warmed anesthetic especially with regard to reducing pain during injection.

Bu çalışmanın amacı Trakya Üniversitesi, Diş Hekimliği Fakültesine başvuran hastalarda bulunan ağız ve diş hastalıklarının ileri sistemik sorunlara ve/veya hasara sebep olma ihtimali bulunan sistemik hastalıklara sahip hasta grupları içindeki sayılarının ve oranlarının değerlendirilmesidir. Trakya Üniversitesi, Diş Hekimliği Fakültesine başvuran rastgele 2000 hasta incelenmiştir. Tedaviye engel olmayan/tıbbi konsültasyon gerekliliği bulunmayan sistemik hastalıklar basit sistemik hastalıklar (SH) olarak, tedavi yapılması uygun olmayan veya tıbbi konsültasyona veya proflaksiye ihtiyaç duyulan sistemik hastalık varlığı ise riskli sistemik hastalık (RSH) olarak değerlendirilmiştir. Hastaların hastaların panaromik ve periapikal radyografları, anamnez formları ve tedavi planları incelenmiş, belirlenen dental problemlerin sayısı ve oranı tespit edilmiştir. Hastaların %39.5’inde SH, SH olan hastaların %31,2’inde ise RSH mevcuttur. RSH en sık ≥ 65 (%28.3) ve 41–62 (%17.5) yaş aralıklarında görülmüştür (P<0.05). En sık görülen RSH ileri kardiyak problemler (%12), geçirilmiş kanser, radyoterapi ve/veya kemoterapi hikayesi (%10.3), gebelik (%9.5) ve aktif kanser, radyoterapi ve/veya kemoterapi hikayesidir (%8, P<0.05). RSH sahip hastalarda en sık görülen dental problemler eksik diş/protetik tedavi gereksinimi (%26.9) ve lokalize periodontal hastalıklardır (%22.7, P<0.05). Detaylı sistemik anamnez ve konsültasyon dental tedaviler esnasında özellikle RSH’a sahip bireylerde yaşanacak sistemik komplikasyonlarda önemli ölçüde azalma sağlayacaktır. Ayrıca diş hekimlerinin olası sistemik komplikasyonlara karşı tıbbi eğitim alması önemlidir.
