Combined orthodontic and surgical correction of an adolescent patient with thin palatal cortex and vertical maxillary excess.

This paper describes the treatment of a male patient aged 14 years who presented with a skeletal class I, vertical maxillary excess, marked increase in overjet, thin palatal cortex and a gummy smile. Considering the severity of his malocclusion and its impact severity on his psychosocial well being, he was managed with a combined approach of Fixed Orthodontic therapy and Orthognathic surgery, even though his growth was not complete. Records of Pre treatment, Post treatment and three years in retention were analyzed and the functional and esthetic results were found to be fairly stable.

Modified technique of resection denture prosthesis fabrication for a patient with segmental mandibulectomy--a case report.

The rehabilitation of patients following maxillary & mandibular resection is challenging. A prosthesis supported with dental implants is often the treatment of choice, but implants cannot be used predictably in all clinical situations. A tissue supported post resection denture is usually the most acceptable treatment option left in these situations. This case report describes management of a patient who had undergone segmental mandibulectomy & subsequently rehabilitated with resection denture prosthesis. Conventional treatment planning was modified at various stages of fabrication to improve the quality of the final prosthesis.

Orthodontic repositioning of a malposed and dilacerated central incisor.

Dilacerated teeth are commonly seen in the maxillary anterior region. They are a cause for concern to both patients as well as parents when such teeth do not erupt or erupt in an unusual position. Careful planning is required while aligning such teeth. Orthodontists often hesitate aligning severely dilacerated teeth due to high chances of failure. A case of a dilacerated and malposed right central incisor in an eleven-year-old male patient is presented here. The tooth was orthodontically repositioned despite its unusual position and severely dilacerated root.

Red cell distribution width as a measure of severity of iron deficiency in iron deficiency anaemia.

Of the various red cell parameters used for distinguishing iron deficiency anaemia (IDA) from beta-thalassaemia trait BTT, red cell distribution width (RDW), which is an objective measure of the degree of anisocytosis, was examined by us for its discriminating value. RDW was measured in 55 patients of IDA and 56 patients of BTT at presentation with the help of an automated haematology analyser. The mean RDWs in IDA and BTT patients were 18.2 +/- 3.8 and 15.1 +/- 1.2 respectively (P < 0.001). In IDA, RDW showed an inverse relationship with the haemoglobin level (r = -0.543; P < 0.001), while no such correlation was observed in BTT patients. An inverse relation was also observed in IDA between RDW and transferrin saturation (TS). Patients with high RDW had low TS and vice versa. The latter finding, although statistically not significant, suggested that the degree of elevation of RDW in IDA could reflect the severity of iron deficiency. Our study revealed that red cell count, which was significantly higher in BTT patients (P < 0.001), the RDW, and the discriminant function (DF) calculated from these two parameters could be useful in distinguishing IDA from BTT. A RDW above 17.1 strongly suggests the presence of IDA. For RDW below 17.1 the DF can be applied for further discrimination. RDW has the advantage of being obtained directly from the analyser, while DF is a calculated value.
