Evaluation of Patient Perceptions After Frenectomy Operations: A Comparison of Carbon Dioxide Laser and Scalpel Techniques
Authors: Haytac M. Cenk , Ozcelik Onur 
Published: October 2006

Background: A frenum that encroaches on the margin of the gingiva may interfere with plaque removal and cause tension. Frenectomy is the complete removal of the frenum that can be made by scalpels or with soft tissue lasers. The aim of this article was to compare the degree of postoperative pain, such as discomfort and functional complications (eating and speech), experienced by patients after two frenectomy operation techniques.Methods: Forty patients requiring frenectomy were randomly assigned to have treatment either with a conventional technique or with a carbon dioxide (CO2) laser. The postoperative pain and functional complication ratings of each patient were recorded using a visual analog scale on days 1 and 7.Results: The results indicated patients treated with the CO2 laser had less postoperative pain and fewer functional complications (speaking and chewing) (P <0.0001 each) and required fewer analgesics (P <0.001) compared to patients treated with the conventional technique.Conclusions: This clinical study indicates that CO2 laser treatment used for frenectomy operations provides better patient perception in terms of postoperative pain and function than that obtained by the scalpel technique. Considering the above advantages, when used correctly, the CO2 laser offers a safe, effective, acceptable, and impressive alternative for frenectomy operations.
Immediate Restoration of Single Implants Placed Immediately After Tooth Extraction
Authors: Barone Antonio , Rispoli Lorena , Vozza Iole , Quaranta Alessandro , Covani Ugo 
Published: October 2006

Background: Some of the original surgical protocols for implant surgery have been reassessed to satisfy the patient's continuously increasing expectation for shorter rehabilitation time, improved esthetics, and increased comfort. The aim of this study was to evaluate the 12‐month clinical success of 18 single‐tooth implants inserted immediately after tooth extraction and restored the same day with non‐functional loading.Methods: A total of 18 patients (12 women and six men), 22 to 60 years old, were enrolled in this study. Eighteen single implants were inserted in fresh extraction sockets and immediately restored with temporary abutments and crowns. All experimental sites showed an absence of fenestrations or dehiscences of the bone walls and a residual gap between implant surfaces and surrounding bone walls ≤2 mm. All temporary prostheses were positioned the same day of surgery and were not in occlusal contact with opposing arches. The comparison between the baseline and 12‐month visits was performed with the Student t test for paired data (statistically significant at a level of α = 0.05).Results: During the 12‐month follow‐up period, one fixture was removed 4 weeks after implant placement following an abscess. All remaining implants healed uneventfully with no complications and were assessed as stable and successful at the 12‐month checkup. No technical complications such as screw loosening, resin fracture, or pain during chewing were registered during the 12‐month period.Conclusions: Within the limits of the data from this study, it can be suggested that immediate placement and restoration of a single implant can be a valid and successful option of treatment in the case of single compromised teeth. Moreover, this treatment protocol eliminates the need for removable provisional restoration and seems to maintain the preexisting architecture of soft and hard tissues in most cases. Nonetheless, further prospective and long‐term studies are required to obtain a better insight into the limitations of this protocol.
The Use of Celecoxib and Dexamethasone for the Prevention and Control of Postoperative Pain After Periodontal Surgery
Authors: Pilatti Gibson Luiz , André dos Santos Fábio , Bianchi Audilene , Cavassim Rodrigo , Tozetto Claudinéia W. 
Published: October 2006

Background: Conventional non‐steroidal anti‐inflammatory drugs have been widely used in the control of postoperative pain, but sparse information is available on the efficacy of celecoxib, a selective cyclooxygenase‐2 inhibitor, or dexamethasone, a steroidal anti‐inflammatory drug, after periodontal surgeries. The purpose of the present study was to compare the use of celecoxib and dexamethasone in the management of pain after mucoperiosteal flap surgery.Methods: A randomized double‐masked cross‐over clinical trial was conducted on 20 patients from 27 to 52 years old with generalized moderate to advanced chronic periodontitis. Mucoperiosteal flap surgeries for scaling and root planing were performed under local anesthesia on at least three quadrants, with a 4‐week interval between. Each quadrant was randomly assigned to one of the following medication protocols: placebo, 4 mg dexamethasone 1 hour before surgery and 8 hours after the first dose, and 200 mg celecoxib 1 hour before surgery and 12 hours after the first dose. Postoperative pain was accessed during the first 8 hours and on the following 3 days using the visual analog scale (VAS), the 101‐point numerical rate scale (NRS‐101), and the four‐point verbal rating scale (VRS‐4).Results: Pain perception was statistically significantly lower in the celecoxib group than in the placebo group during the first 4 hours using VAS (P = 0.01) and at 1, 2, 3, 4, 6, and 7 hours using NRS‐101 (P = 0.03). The level of pain was lower in the dexamethasone group than in the placebo only at the 3‐hour period (P = 0.001). Statistically significant differences could be found among the groups at 1 hour (P = 0.015), 3 hours (P = 0.004), 4 hours (P = 0.02), and 7 hours (P = 0.05) using VRS‐4. There was no statistically significant difference between the celecoxib and dexamethasone groups.Conclusion: The findings of this study suggest that the preemptive and postoperative use of celecoxib or dexamethasone were effective in the management of postoperative pain following open‐flap debridement.
The Effects of Interimplant Distances on Papilla Formation and Crestal Resorption in Implants With a Morse Cone Connection and a Platform Switch: A Histomorphometric Study in Dogs
Authors: Novaes Arthur B. , de Oliveira Rafael R. , Muglia Valdir A. , Papalexiou Vula , Taba Mário 
Published: October 2006

Background: Implant esthetics have been the focus of attention for the last few years, and one of the most important points is the effect that interimplant distances can have on papilla formation and bone loss. The aim of this study was to evaluate the effect that distances of 1, 2, and 3 mm between implants after prosthetic restoration will have on crestal bone resorption (from the top of the implant to the bone crest [TI‐BC]) and bone resorption (from the top of the implant to the first bone‐to‐implant contact TI‐BIC) in two‐stage implants used in a submerged and non‐submerged protocol.Methods: The mandibular bilateral premolars of seven dogs were extracted, and after 12 weeks, each dog received eight implants. The implants were placed so that three interimplant contact points were created, with 1‐mm (group 1), 2‐mm (group 2), and 3‐mm (group 3) distances constructed on each side. The sides and the position of the groups were randomly selected. After 12 weeks, the implants received metallic prostheses with 5 mm between the contact point and the bone crest. After 8 weeks more, the animals were sacrificed.Results: The TI‐BC was 0.20 and 0.18 mm for group 1, 0.15 and 0.14 mm for group 2, and 0.15 and 0.15 mm for group 3 for non‐submerged and submerged implants, respectively. At the proximal region, the TI‐BC was 0.16 mm for non‐submerged and 0.16 mm for submerged implants. The TI‐BIC was 0.32 and 0.30 mm for group 1, 0.19 and 0.21 mm for group 2, and 0.30 and 0.24 mm for group 3 for non‐submerged and submerged implants, respectively. At the proximal region, the TI‐BIC was 0.26 mm for non‐submerged and 0.25 mm for submerged implants. There was no statistical difference for any of the parameters (analysis of variance [ANOVA]).Conclusion: Distances of 1, 2, and 3 mm between implants do not result in statistically significant differences on TI‐BC and TI‐BIC around submerged or non‐submerged implants with a Morse cone connection and a platform switch.
Biological structure and health implications from tooth size at Mission San Luis de Apalachee

Published: October 2006

AbstractThis study analyzes dental metric variation to examine the biological structure of the native population at Mission San Luis de Apalachee, a late 17th century mission located in the Apalachee Province of Spanish colonial Florida. Three topics are addressed: (1) comparison of tooth sizes among adult and subadults, (2) analysis of the bio‐spatial structure of skeletons within the church area, and (3) comparison of phenotypic profiles of individuals interred within coffins in the ritual nucleus of the church: the altar region. Analyses indicate that subadults had smaller average tooth sizes than adults for the posterior dentition that was particularly evident in mandibular nonpolar molars and premolars. This disparity, also documented in two other mission populations, likely represents ontogenetic stress and resulting increased mortality among those most at risk for early death. Analysis of the spatial structure of graves failed to document biological structuring by side of the aisle or by burial row, although some gross differences were evident when front, middle, and rear church burials were compared. Individuals buried in coffins within the same row were phenotypically similar to one another. However, inter‐row comparisons indicated lack of phenotypic similarity among all coffin interments. These analyses suggest maintenance of kin‐structured burial for elites alone within the San Luis community. Am J Phys Anthropol, 2007. © 2006 Wiley‐Liss, Inc.
