RESUMEN
Sixty healthy clinical edentulous patients (thirty male and thirty female) were chosen for the study. Panoramic and lateral cephalometric radiographs were taken of each patient. The amount of bone loss was estimated from the panoramic radiographs as per the formula proposed by Wical and Scoop. The rate of mandibular residual resorbed ridge (RRR) expressed as percentage of bone loss per year was then computed. The correlation between the mandibular RRR and gonial cortical thickness and the percentage of cortical bone at the symphysis was tested. These parameters were also compared between the male and female patients. The rate of mandibular RRR, expressed as percentage of bone loss per year, was found to be indirectly correlated with the cortical thickness at gonion as measured from the panaromic and the lateral cephalometric radiographs. The values of students 't' test for mean differences between the female and the male patients with respect to the rate of mandibular RRR and the cortical thickness at the gonion were found to be statistically significant.

The need for dental treatment in paediatric dental patients is immense. The present study was carried out in fifty children in the age group of five to ten years of age with recurrent episodes of dentoalveolar infection. Advanced pulpal infections led to torsion in 54 percent, premature eruption in 46 percent, crater like bone loss in 36 percent, sequestration and dilaceration in 10 percent and 6 percent respectively. Most of the developmental disturbances could have been avoided with timely antibiotics and endodontic intervention.

A case of fourteen year old healthy girl with complaint of a discharging sinus on the lower right side of face is reported. All teeth were vital and there was no evidence of periodontitis. There was no history of extraction of a tooth. Total leucocyte count, differential leucocyte count, fasting blood sugar, chest x-ray and routine urine examination were within normal limits. Actinomycosis and scrofuloderma which simulate such a condition were ruled out by culture study. The intraoral periapical x-ray of mandibular molar showed questionable periapical changes at the time of presentation. But definite osteolysis was observed in the repeat radiograph after three months. It was decided to extract the second molar and curette the sinus tract. The extraction proved to be difficult. On examination of the extracted tooth, it was found that the mandibular second molar and second premolar were fused together. The radiograph of the tooth taken after extraction showed confluence of the premolar pulp with the periodontal membrane. On follow up, the lesion was found to heal satisfactorily.
