摘要:

a recently discovered oral disease processof infectious origin, characterized by nonradiographically detectable, hollow, pathologic, alveolar cavitational lesions of significant size, is described. This oral infectious disease process, termed alveolar cavitational osteopathosis, is causally implicated not only in the genesis of certain craniofacial pain syndromes, among them idiopathic trigeminal neuralgia and atypical facial pain, but also in chronic pain syndromes remote from the craniofacial region including the back, chest, arms, legs and cervical areas.A diagnostic process is presented which serves to define the locus of nonradiographically detectable alveolar cavitational osteopathosis and correlates a given pathological site to a given area of pain. Comprehensive schematics have been developed defining the pain pathways emanating from the oral cavity and their specific relationship to sites of perceived pain both in the craniofacial region and other areas of the body.The treatment modality described serves to induce bone growth within the cavitational lesions, resulting in the subsequent eradication of the cavity. The abolition of osteopathosis results in significant or total disappearance of pain symptomatology.

摘要:

this study compared the effect of four treatmentmodalities on connective tissue attachment. Ligature‐induced periodontitis was established around the mandibular premolare of five young beagle dogs over 8 weeks. Following a 2‐week period without ligatures, a reference dog was sacrificed to estimate the extent and nature of the disease. Three dogs received flap procedures in one mandibular posterior segment, and the six experimental roots were treated with citric acid (pH 1) for 3 minutes; the contralateral mandibular segments received flap procedures and the roots were treated with 4% Chlorhexidine gluconate in the Hibiclens® preparation for 3 minutes. One segment of the control dog received flap procedures, and the roots were treated with sterile normal saline; the contralateral segment received closed root planing. The experimental dogs were sacrificed 1, 2 and 3 months after treatment. The control dog was sacrificed 3 months postoperatively. One week before sacrifice each dog received a Procion dye injection.At sacrifice the study segments of all four treated dogs were clinically healthy, with no observable differences between the different treatment modalities. Histologically, the 1‐ and 3‐month Chlorhexidine, the 3‐month saline and 3‐month root planed specimens had long junctional epithelial adhesions with little connective tissue attachment. The 2‐month Chlorhexidine and all citric acid‐treated sections showed appreciable amounts of new connective tissue attachment. Some 2‐month and 3‐month citric acid and 2‐month Chlorhexidine sections showed cementum over the apical portion of the long junctional epithelium. The frequency of occurrence and the length of cementum overlapping epithelium increased appreciably over time.Chlorhexidine was less predictable than citric acid in enhancing connective tissue attachment. When compared with the size of the periodontally involved area in the reference dog, all new connective tissue attachment could have occurred on uninvolved surfaces denuded by the root planing or flap procedures. The finding of cementum overlying the junctional epithelium indicates that coronal migration of connective tissue attachment is possible.

摘要:

in a 22‐year‐old female patient, advanced localized periodontal destruction was observed. The planned treatment consisted of oral hygiene instructions, professional plaque control, deep scaling and root planing and finally modified Widman flap surgery. One molar had to be extracted but was left untreated initially as a control. During the treatment period of 9 months and during 1 year thereafter, samples were taken of the subgingival plaque for darkfield microscopy. The unplanned use of amoxicillin by the patient for a middle ear infection resulted in a suppression below detection level of spirochetes at the investigated sites. At the nontreated control site, the absence of spirochetes was accompanied by a 3‐mm reduction of pocket depth and a 2‐mm gain in clinical probing attachment, while some formation of new alveolar bone was observed. At the treated sites, clinical improvement was observed. However, a distinction between the effect of the periodontal therapy and the nonscheduled use of amoxicillin could not be made at the treated sites. It is concluded that a single course of systemically administered amoxicillin changed the composition of the subgingival microflora over a long period of time (17 months) and had a beneficial effect upon the status of the periodontium.

摘要:

the literature related to smoking and periodontal diseaseis reviewed. The effects of smoking on oral hygiene, gingivitis, necrotizing gingivitis, periodontitis, bacteria and the host's response are presented. From this review it is apparent that while the relationship between smoking and periodontal disease needs further study, smoking is detrimental to periodontal health as it worsens the oral hygiene status and depresses the host's defense posture.

摘要:

eubacterium brachy, a gram‐positive anaerobic rod, has been implicated by cultural studies to be associated with the microflora of periodontal diseases. Serum samples from 184 clinically characterized patients were evaluated in a standardized enzyme‐linked immunosorbent assay (ELISA) for reactivity toE. brachyantigens. Sera from clinically healthy subjects (HS) served as controls. Sera from rapidly progressive periodontitis (RP) patients demonstrated significantly greater reactivity by ELISA than did HS when reactivity with E. brachy antigens was determined (P0.05). The possible significance of these findings and the importance of an extracellular antigen ofE. brachyin the immunopathology of periodontal diseases are discussed.

摘要:

the sonic scaler, the curet, and the reciprocatingmotor‐driven diamond tip were evaluated by comparing the number of rough root surfaces produced by each device in recontouring overhanging root‐surface margins of amalgam and composite resin restorations. Ninety extracted human teeth were restored with amalgam or composite resin so that overhangs were created. Each instrument was used to remove 30 overhangs. The root surfaces apical to the overhangs were photographed under the scanning electron microscope at a magnification of × 140 and compared by five dentists, in a single‐blind manner, with two control photomicrographs of surfaces classified as rough (treated with a coarse diamond bur) or not rough (treated with a greenstone). The number of rough responses for each instrument were compared statistically. For both restorative materials, the sonic sealer produced a significantly greater number of rough responses than did the other two instruments. Similar comparisons between the curets and the diamond‐tip system showed no significant differences. No differences in the number of gaps produced between restoration and tooth were noted among the instruments. Clinical ease of overhang removal was greatest for the reciprocating motor‐driven diamond tip and least for the curet. The approximate time to remove an overhang from a tooth was 3 minutes for the motor‐driven diamond tip, 7 minutes for the sonic sealer and 15 minutes for the curet.

摘要:

this controlled, double‐blind, split‐mouth studywas designed to evaluate postoperative pain experience following periodontal surgery on 20 patients. Two commercially available local anesthetic agents, bupivacaine HCl and lidocaine HCl, were used. Periodontal surgeries were standardized to minimize differences in difficulty, extent and time. A patient questionnaire was used to collect data for the 24‐hour observation period following periodontal surgery. During this period, pain perception was assessed by visual analogue scales. The results indicated that when bupivacaine was used, there was less postoperative pain, fewer postoperative analgesics taken and a longer period of “numbness” (anesthesia) as compared to lidocaine. The patients expressed a strong preference for bupivacaine over lidocaine.
