Cutaneous sinus tract from an impacted tooth: A case report with one step surgical treatment
No full textCutaneous sinuses of dental origin are well recognized pathological conditions whose pathogenesis is related to periapical or pericoronal acute inflammatory processes; nevertheless they have to be differentiated from several skin lesions of the face and neck. The case of an edentulous patient with a skin sinus in the left submandibular region from an impacted lower first molar is presented. Clinical and radiographic features of this case are reported, pathogenesis and differential diagnosis are analysed and one-step surgical treatment is described and discussed. Correlation with teeth has always to be made, also in edentulous patients, in which impacted teeth can be occasionally found. If these patients wear total dentures, a one-step surgical intervention can be performed to allow at the same time the best aesthetical results and the immediate functional rehabilitation
Odontomas and supernumerary teeth: is there a common origin?
No full textThe aim of the present work is to analyze all scientific evidence to verify whether similarities supporting a unified explanation for odontomas and supernumerary teeth exist. A literature search was first conducted for epidemiologic studies indexed by PubMed, to verify their worldwide incidence. The analysis of the literature data shows some interesting similarities between odontomas and supernumerary teeth concerning their topographic distribution and pathologic manifestations. There is also some indication of common genetic and immuno-histochemical factors. Although from a nosological point of view, odontomas and supernumeraries are classified as distinct entities, they seem to be the expression of the same pathologic process, either malformative or hamartomatous
Antibiotic prophylaxis: reasoned choice and not casual use
Full text linkCurrently, the scientific world’s position is clear as far as distant site infections are concerned, involving mainly the endocardium but also prosthetic joints, indwelling venous catheters and cardiovascular implantable electronic devices, with a dramatic reduction of the number of subjects in which antibiotic prophylaxis is considered to be necessary. The situation is very different with regard to the antibiotic prophylaxis of surgical site infections since in most oral procedures there are no guidelines or recommendations concerning the use, or not, of antibiotics provided by associations of oral and maxillofacial surgeons worldwide
Effectiveness of a personalized device in the evaluation of mandibular second molar periodontal healing after surgical extraction of adjacent third molar
Full text linkThe primary aim of the present study was to validate the effectiveness of a personalized device able to guide periodontal probing in evaluation of second molar periodontal healing after adjacent third molar surgical extraction. Secondarily, the study analyzed if any patient and tooth related factors affected the second molar periodontal healing as well as if they were able to affect the periodontal probing depth performed with or without the personalized device. Materials and methods: Thirty-five lower second molars were evaluated after extraction of the adjacent third molar. Pre-operative as well as 3 and 12
month post-operative probing depths of the distal surface of the second molar were evaluated. All measurements were taken by two different methods: standard two-point and four-point probing using a personalized onlay-type guide. Periapical radiographs were also evaluated. The Pearson product moment and the general linear model with backward stepwise procedure were used for inferential statistics.
Results: The mean 12-month post-operative probing depth/mean pre-operative probing depth ratio obtained with the guided probing method showed a highly significant effect on the 12-month radiographic post-operative/pre-operative radiographic measure ratio. None of the examined patient- or tooth-related factors showed a significant effect on pre-operative/12-month post-operative radiographic
measure ratio. Conclusions: The use of the proposed personalized device seems to provide a more reliable
estimate of second molar periodontal healing after adjacent third molar surgical extraction. No patient- or tooth-related factors seem to be able to affect either second molar periodontal healing or probing depth measures obtained with or without the personalized device in individuals younger than 25 years old. It can be therefore recommended that lower third molar surgical extraction be performed in young adults

A sixteen year sample of surgically treated supernumerary teeth
No full textIntroduction Supernumerary teeth represent a numerical dental anomaly in which more teeth than the norm are present in the dentition. A sixteen year sample of supernumerary teeth has been reviewed in order to analyse epidemiological data, morphological and topographic features of these teeth, especially of those located in the praemaxillary region. Materials and methods All cases in which supernumerary teeth were surgically treated from 1991 to 2006 at the Oral Surgery Unito of the "Sapienza" University of Rome have been reviewed. Results 118 Caucasian subjects with supernumerary teeth have been reviewed in the range of age comprised between 5 and 42 years: 191 SNTs were collected, 136 from the upper jaw and 55 from the mandible. In the maxilla the incisor region was more frequently involved (67.65%), while in the mandible the one most frequently involved was the premolar region (69.1%). Conoid was the most frequent type of supernumerary teeth. Uneruption of the contiguous permanent teeth was the most commonly associated pathological condition, found in 81 out of the 191 cases of supernumerary teeth (40 patients, 42.4%). Tuberculated, infundibuliform and incisiform-shaped teeth caused uneruption of permanent teeth more frequently than the other morphological types of supernumerary teeth. Conclusion In the upper incisor area, the extraction of SNT is mandatory as early as they are diagnosed, especially if they are tuberculated, infundibuliform and incisiform-shaped, if they are located palatally or just in the middle of the ridge and when more than one SNT is present
Antibacterial prophylaxis of surgical site infections in oral surgery: not only and not always systemic antibiotics
Full text linkAntibacterial prophylaxis is a set of treatment measures, including antibiotic prophylaxis, under surgeon’s responsibility. If local measures are always to be applied, antibiotic prophylaxis administration needs a careful case selection in order to avoid indiscriminate prescription. Local measures include the following: use of sterile instrumentation and special devices to prevent surgical site contamination; good surgical treatment; pre-surgical treatment of acute local infections; pre-surgical calculus removal and perioperative plaque control; post-surgical follow-up. Antibiotic prophylaxis should follow the following five basic principles: only procedures that have high risk of infection need antibiotic prophylaxis; an adequate antibiotic should be chosen; a high dose of antibiotic should be used; the time of administration should be correct; antibiotic activity should be as short as possible
