Aims: To describe the non-surgical endodontic management of a maxillary first molar with severe, symptomatic external inflammatory root resorption in an adolescent patient, and to report the 12-month outcome. Presentation of Case: A 15-year-old boy presented with spontaneous pain and marked tenderness to percussion in the maxillary right first molar (tooth 16). A periapical radiograph showed advanced external resorption, most severe in the palatal and distobuccal roots, which had become considerably shortened. Root canal treatment was started without delay. Because the resorptive tissue was richly vascularised, controlling intracanal bleeding was difficult and time-consuming despite the short canals. After haemostasis was achieved, a dense calcium hydroxide dressing was placed in all canals. Three weeks later, the patient was almost free of symptoms, and the dressing was intact with no sign of infection. As the lesion was an external inflammatory resorption, each canal was then obturated along its full length with mineral trioxide aggregate (MTA). Discussion: Early diagnosis, elimination of the microbial stimulus, and a calcium hydroxide dressing are central to arresting inflammatory resorption. Full-length MTA obturation was chosen to seal the resorptive communications and to provide a well-sealing, biocompatible barrier in the weakened roots. Conclusion: Prompt endodontic intervention with calcium hydroxide followed by MTA obturation arrested the resorption and preserved the tooth, which remained asymptomatic and functional at the 12-month review.

Bu eser, endodontik tedavi görmüş dişlerin restorasyonunu tedavinin tamamlayıcı değil belirleyici aşaması olarak ele almakta; kökten korona bütünlüğünü doku koruma, materyal seçimi, adeziv simantasyon, ferrule yönetimi ve endokron uygulamaları ekseninde kanıta dayalı biçimde incelemektedir.Temel savı, endodontik ve restoratif aşamaların birbirinden bağımsız iki uygulama alanı değil, aynı tedavi bütünlüğünün ayrılmaz parçaları olduğudur. Kanaldaki biyolojik başarı, koronal sızdırmazlığın sağlanamadığı koşullarda riske girmekte; koronal restorasyonun kalitesi ise kanalın uzun dönem kaderini doğrudan belirlemektedir. Geleneksel yaklaşımın tam kron ve kanal içi post odaklı anlayışının aksine, güncel stratejiler minimum madde kaybıyla maksimum fonksiyonel çıktıyı hedeflemektedir. Minimal invaziv felsefeyi merkeze alan kitap; kalan diş dokusunun miktarı ve kalitesi, ferrule kavramının klinik sınırları, post endikasyonunun güncel kriterleri, endokronların biyomekanik avantajları, adeziv simantasyonun incelikleri ve oklüzal yüklerin restorasyon ömrü üzerindeki etkisini bütüncül bir akışla ele almaktadır. Klinisyenlere her vakada en konservatif, en öngörülebilir

Background/Objectives: Calvarial tumors form a heterogeneous group of benign and malignant lesions, and institutional series remain limited, particularly from Türkiye. This study aimed to describe the clinical, radiological, histopathological, and surgical features and histology-specific outcomes of calvarial tumors treated at a single neurosurgical center. Methods: We retrospectively reviewed 42 patients who underwent surgery for histopathologically confirmed tumors and tumor-like lesions of the cranial vault between 2019 and 2024. Clinical, imaging, histopathological, surgical, and follow-up data were analyzed. Results: The cohort comprised 24 men and 18 women (mean age 42.6 ± 15.3 years; range 7–78). A palpable mass was the most common complaint (64%), and the frontal bone was the most common site (38%). Lesions were benign in 25 patients (60%, including 6 with fibrous dysplasia) and malignant in 17 (40%); osteoma and metastasis were the leading diagnoses. Malignant tumors were larger and had a shorter symptom duration than benign lesions. Total resection was achieved in 36 patients (86%). During a mean follow-up of 32 months, recurrence occurred in 8% (95% CI 2–25%) of benign and 35% (95% CI 17–59%) of malignant tumors (p = 0.045); 8 recurrences occurred after total resection. Conclusions: In this surgical series, a short symptom duration, larger lesion size, and destructive CT features were associated with malignancy, although their diagnostic accuracy requires validation in larger cohorts. Recurrence was uncommon in those with benign lesions but occurred in about one-third of those with malignant tumors, which therefore require multidisciplinary management and close surveillance. Because recurrence also occurred after total resection, the extent of resection alone did not ensure local control.
