Restoration of severly damaged teeth requires comprehensive, carefully planned pretreatment. Usually, the teeth with fractures or caries extended upto or below the alveolar crest, can be treated by conventional surgical crown lengthening at the expense of supporting bone. Forced eruption or extrusion of teeth is an alternative procodure to overcome problems with dental esthetics and removing of supporting tissues. Two case reports are used as a basis for reviewing the forced eruption with and without supracrestal fibrotomy.

The present clinical & histologic trial was designed to investigate the inductive effect of palatal connective tissue on the alveolar mucosa. 11 subjects 19-49 years of age showing good performance in oral hygiene were selected from Shiraz dental school patients. The test tooth (incisor, canine or premolar) had keratinized gingiva equal of less than 2 mm. This tooth together with the adjacent mesial and distal teeth should be free of gingivitis or periodontitis. The base line clinical measurements were done on the test tooth and mesial and distal adjacent teeth. Surgical phase included a mucosal flap at recipient site (with minimal thickness) at the mucogingival line of the test tooth extending somewhat to buccal of adjacent mesial & distal teeth. The remaining tissue on the bone of the area was removed and the bone was exposed. At the donor site (palate), a mucosal flap was reflected and a piece of connective tissue with thickness of 1-2 mm was removed and sutured at the recipient site & then it was covered by overlying flap. The sutures were removed after 7 days. Maintenance phase was performed by regular follow up visits up to 6 months. Six months postoperatively the base line measurements were repeated. Biopsy specimens were obtained from the grafted area and the adjacent intact alveolar mucosa. The specimens were fixed and sent for histologic examination. Data analysis showed that the keratinized and attached gingiva of test teeth and the adjacent mesial & distal teeth increased significantly clinically the added keratinized gingiva was tightly bound to underlying tissues. The probing depth & gingival recession of test teeth did not increased significantly. The light microscopic histoligic examination showed keratinization in 80% of cases. In 30% of cases dense well organized collagen bundles was seen in lamina propria. This study proved that palatal connective tissue graft can induce nonkeratinized alveolar mucosa into masticatory mucosa.

Statement of Problem: The origin of Dental Unit Water Lines (DUWL) contamination is specially related to the formation of biofilm which is composed of microorganisms within water and is located on the tubing lines. Purpose: In this descriptive study, we evaluated the degree of contamination with Gram positive and Gram negative bacteria in DUWLs of the dent-al school and also determined the efficacy of flushing on reducing its microbial count. Materials and Methods: Thirty dental units from all the departments of dental school in Tehran University of Medical Sciences were selected for this study. Sampling consisted of a two step procedure before and after one minute of flushing. The samples were taken from air/water line of each selected dental unit separately. Air/water syringe of each unit was completely disinfected with Deconex before sampling. Results: The range of the contamination varied from190 to 23 ×10 5 CFU/ml. The bacterial contamination included anaerobic Gram negative bacilli, non-fermenting Gram negative bacteria, Gram positive cocci and Gram positive bacilli. In all the samples taken from water taps, contamination was noted, varying from 25 to 1700 CFU/ml. This was significantly lower than the contamination of air/water syringe of the dental units. Conclusion: Applying the right principles for infection control such as using disinfectants or sterile water in dental settings and daily flushing before visiting patients can be of great significance. KEY WORDS: Dental unit; Water line; Bacterial contamination; Flushing
