Comparison of the Accuracy of Manual and Digital Cephalometric Prediction Methods in Orthognathic Surgical Planning: A Pilot Study.

Objective: To compare and evaluate the reliability of manual and digital cephalometric prediction methods in orthognathic surgical planning.

Methods: Ten adults (5 females and 5 males) with skeletal class III malocclusion were included. The mean patient age was 21.

Effects of a porphyrazine derivative on some developmental characteristics of Drosophila melanogaster.

In this study, the effects of a porphyrazine derivative, [octakis (2-trimethylammoniumethyl thio) porphyrazinatocobalt] octaiodide (CoPzq), were explored on the developmental characteristics, sex ratio and egg fertility of Drosophila melanogaster. CoPzq was preferred in the study due to its probability to be used as a chemotherapeutic agent in medicine. As a result of the application of CoPzq, a phenotypic abnormality was revealed within the individuals of F1 and F2 generation of Drosophila.

The assessment of unaided visual examination, intraoral camera and operating microscope for the detection of occlusal caries lesions.

This study compared the efficiency of unaided visual examination, intraoral camera and operating microscope according to a visual scoring system (ERK) at occlusal caries detection. A total of 84 extracted human molars were mounted to create mouth models with a premolar in contact on both sides. The models were examined in a phantom head simulating clinical conditions by four observers using the three techniques: unaided visual examination, an intraoral camera and on operating microscope according to the ERK scale.
