Objective:The aim of this study was to determine the prevalence of double teeth, hypodontia, microdontia, and hyperdontia of primary teeth in Turkish children.Methods:The study group comprised 1149 children (554 girls, 595 boys). The children were examined in twelve local nurseries in Sivas, Turkiye. Clinical data were collected by four dentists according to Kreiborg criteria; which includes double teeth, hypodontia, microdontia, and supernumerary teeth. Statistical analysis of the data was performed using the chi-square test.Results:Dental anomalies were found in 2.0% of children. The distribution of dental anomalies were significantly more frequent (P=.023) in boys (2.9%, n=17) than in girls (1.1%, n=6). In relation to anomaly frequencies at different ages, no difference was found (P = .760).Conclusion:Double teeth were the most frequently (1.3%) observed anomaly. The other anomalies followed as; 0.3% supernumerary teeth, 0.3% microdontia, 0.2% hypodontia. Identification of dental anomalies in the anterior region at an early age is of great importance for esthetic and orthodontic treatment planning.

All file and irrigation systems extruded debris apically. PIPS activation was associated with significantly more extrusion debris in curved canals compared with no activation.

None of the techniques removed the CH dressing completely. Laser-activated irrigation was significantly more effective than needle irrigation.
