Report of Two Cases with Unusual Extraction of the Lower Incisor

Two patients received orthodontic treatment after the unusual procedure of extracting the lower incisors. The first case was a young male, whose lower left lateral incisor and three first premolars were removed. The lower left canine and first premolar were used as lower left lateral incisor and canine, respectively. The second case was an adult female, whose lower right central incisor and two upper first premolars were extracted. The three remaining lower incisors were occluded with the four upper incisors. Both cases had good occlusion and profiles, and the patients were satisfied with the results

Dentofacial Deformities Seen in Two Sisters and a Brother

Three cases of similar dentofacial deformities seen in two sisters and a brother are introduced and their orthodontic aspects considered. The first case showed excessive dentofacial deformity for which surgical orthodontic treatment was indicated, but at the patient\u27s request orthodontic treatment alone was attempted with unsatisfactory results. The second case presented asymmetrical skeletal mandibular protrusion, which was satisfactorily treated with surgical orthodontic methods. In the third case, satisfactory results were obtainable with orthodontic methods alone, because treatment was begun during the mixed dentition period. Had this patient not received treatment he would certainly have developed the same mandibular asymmetry exhibited by his elder siblings. The results of the third case suggest an effective role for orthodontic treatment in the prevention of dentofacial deformities, and underscore the importance of early treatment

The correlations of the breath sound with the depth of respiratory and the medical condition of atelectasis

In this paper, we report one of the methods to distinguish patient’s atelectasis condition from the normal condition based on the spectral analysis of the auscultation by the electric stethoscope. Atelectasis is a respiratory collapse defined as the lack of gas exchange within alveoli, and due to airway obstruction, or compression of the lung. This atelectasis condition is conventionally founded as the asymmetric sounds of the left lung area and right one by auscultation using air-conducted stethoscope. We aimed to this auscultation diagnose objectively. We assume that the cumulative sound powers of auscultation sound relate the air-flow volume of the respiratory, and show the power spectrums of auscultation sounds in several cases of respiratory types. The results show that the left-right symmetry of the sound’s powers decreases in the atelectasis cases
