Assessment of the prevalence and characteristics of dens invaginatus in a sample of Turkish Anatolian population

Objective: The objective of this study was to assess the prevalence and characteristics of dens invaginatus in anterior teeth and to classify the type of dens invaginatus in a sample of Turkish Anatolian population. Study design: A retrospective study was performed using full-mouth periapical and panoramic radiographs of 1012 patients. Maxillary and mandibular anterior teeth were evaluated for the presence and characteristics of dens invaginatus. Statistical evaluation of the presence of dens invaginatus related to gender was performed by the Pearson chi-squared test. Results: Dens invaginatus was observed in 13 out of 1012 subjects and in only maxillary lateral incisors. There were no periapical lesions in teeth with types I and II, whereas both of the subjects with type III had apical periodontitis at the time of referral. Males and females were almost equally affected by dens invaginatus (P= 0.98). Conclusion: The anomaly was detected in only maxillary lateral incisors with no gender difference and the most commonly observed type of dens invaginatus was type I (81.25%)

Assessments of ReDo buccal mucosal urethroplasty in terms of functional outcomes

© 2022, The Author(s), under exclusive licence to Springer Nature B.V.Purpose: We aimed to assess the success rates and functional outcomes of ReDo buccal mucosal graft urethroplasty (BMGU) following failed primary BMGU and evaluate the oral morbidity and changes in quality of life (QoL) after this surgery. Materials and methods: Data of the patients with recurrent anterior urethral stricture who underwent ReDo BMGU after failed primary BMGU were retrospectively reviewed. The collected data included the results of the urethral stricture surgery patient-reported outcome measure-lower urinary tract symptoms (USS-PROM-LUTS) and euro-quality of life visual analog scale (EQ-VAS) questionnaires performed preoperatively before and one year after surgery. The cohort was divided into two groups according to procedural success, and these groups were compared. Results: Thirty-two men patients were included. Among these, twenty-seven (84.3%) cases were considered successful following ReDo BMGU. The pre-ReDo BMGU mean stricture length was significantly longer in the failure group (2.3 ± 0.6 vs. 4.4 ± 1.2 cm, p = 0.001). Except for one patient with persistent oral numbness, no severe complication was reported postoperatively in the first year. The mean USS-PROM-LUTS score decreased significantly, while the mean LUTS-related quality of life score increased significantly following ReDo BMGU (p < 0.001, p < 0.001). In addition, the mean total EQ-VAS score increased significantly from 62.75 to 78.45, indicating remarkable improvement (p < 0.001). Conclusions: Although less favorable outcomes can be anticipated in ReDo BMGU due to extensive scar tissue formation and reduced vascularity, high success and patient satisfaction rates and low oral morbidity rates were detected in ReDo BMGU cases

The Effect of Medicaments Used in Endodontic Regeneration Technique on the Dislocation Resistance of Mineral Trioxide Aggregate to Root Canal Dentin

Introduction: The aim of this study was to evaluate the effect of calcium hydroxide (CH) and antibiotic pastes, including a mixture of metronidazole and ciprofloxacin, with and without minocycline or cefaclor, on the dislocation resistance of mineral trioxide aggregate (MTA) to root dentin. Methods: Eighty single-rooted human mandibular premolars were selected. The teeth were prepared by using the ProTaper system. The prepared teeth were then instrumented to a #6 Peeso reamer to obtain a standard internal diameter of 1.5 mm. The reamers were passed 1 mm beyond apex to simulate immature teeth. The specimens were then randomly divided into a control group (no intracanal medicament was used) and 4 experimental groups that were treated with an intracanal medicament: CH, doubl'e antibiotic paste (DAP) with metronidazole and ciprofloxacin, triple antibiotic paste (TAP) with minocycline, or TAP with cefaclor (n = 16). After 3 weeks, the medicaments were removed, and approximately 3 mm of MTA was placed in the coronal third of the canals. A push-out test was used to measure the dislocation resistance between the root dentin and MTA. Data were analyzed by using one-way analysis of variance and Tukey post hoc tests. Results: The dislocation resistance values of the CH, TAP with minocycline, and TAP with cefaclor groups were similar to those of the control group (P > .05), whereas the DAP group had the lowest dislocation resistance when compared with the other groups (P < .05). Overall, there was a predominance of cohesive fail-. ures between root dentin and MTA. Conclusions: The results of this study indicate that the application of DAP as an intracanal medicament reduced the dislocation resistance of MTA to root dentin
