Materials and Methods: Forty-five mature maxillary and mandibular anterior teeth, extracted for periodontal reasons, were collected. After the chemo-mechanical instrumentation of the root canal, teeth were filled with four endodontic sealers (Endomethason, AH+, Canason and Apexit). Depending on canal sealers and the CEJ (Cement Enamel Junction), teeth were divided into 8 experimental groups (n = 5) and one control group/CG (n = 5). Teeth color changes (L*a*b*/CIE Commission Internationaled’ Eclaraige) were determinated by a spectrophotometer Vita Easyshade in 4 stages (Baseline, Week 0, 4 and 12). Results: Between the EOCEJ and CG for the parameter L*, there was a statistical significance (p 0.05). The L*a*b* results were: L* (83.6 ± 4.8 → 83.6 ± 4.9);a* (﹣2.68 ± 1.02 → ﹣1.12 ± 0.72) and b* (20.2 ± 4.5 → 24.4 ± 4.2). Conclusions: All endodontic sealers may cause teeth discoloration.展开更多

In this report, we discuss a case of a patient with Gorlin Goltz Syndrome, who was 16 years old when first admitted for an initial appointment. The patient was diagnosed, treated and followed up for 7 years to present day. This syndrome is associated with a broad spectrum of anomalies and neoplasms as basal cell carcinomas, odontogenic keratocysts, palmar and/or plantar pits, and ectopic calcifications of the falx cerebri. It affects multiple organ systems, which include skeletal, teeth, jaw, skin, eyes, reproductive organs, and neural system. All the features however, are rarely observed in a single patient. The following paper presents the significance of early diagnosis of Gorlin Goltz Syndrome and the importance of a multidisciplinary approach in providing proper treatment for the patient.展开更多
