ABSTRACT
The rehabilitation of patients with edentulous alveolar ridge is always a challenge, more so in case of a long standing atrophic mandible. Mandible, the largest movable bone in the maxillofacial skeleton is associated with many soft tissue attachments which imparts dislodging forces to prosthesis. In addition to this, the rate of resorption of the mandibular ridge is four times that of the maxilla. These factors make the environment of the mandibular arch less favorable to complete denture stability and retention. An ideal solution would be to augment the atrophic alveolar ridge with native bone of the individual which shall eliminate the possible complications, associated with conventional ridge augmentation procedures. With advent of modern technology, and increased biological understanding, the principles of distraction osteogenesis are increasingly being applied to the craniofacial skeleton and have been found to be a viable option in augmenting the native alveolar bone in the mandible. Here the application of an indigenous stainless steel vertical alveolar distraction device to augment atrophic anterior mandibular ridge is assessed in six patients.
ABSTRACT
BACKGROUND: The aim of this study was to compare the effect of adrenaline on blood glucose concentration in patients with diabetes undergoing tooth extraction under local anesthesia and also to find out whether blood glucose concentration differs if local anesthetics are injected in clinical doses with and without adrenaline. METHODS: Patients included had a tooth in need of extraction, were in the 25-55 years age group, had a random blood sugar level ≤140 mg/dL and were on oral antidiabetic drugs. The 25 patients in Group A were injected with 2 mL of lignocaine hydrochloride without adrenaline (xylocaine 2%) and the other 25 patients (Group B) were injected with 2 mL lignocaine hydrochloride along with adrenaline 1:80,000. Serial blood glucose estimations were made at regular intervals of 10 min before local anesthesia and subsequently 10 and 20 min after local anesthesia. RESULTS: A statistically significant difference of the mean blood glucose concentration was noticed at three different time intervals between the two groups. CONCLUSIONS: Dental local anesthetic solutions containing adrenaline may safely be used in patients with diabetes who had taken their hypoglycemic medications preoperatively.
