From the available literature it appears that the total numbers of leukocytes and plasma levels of C-reactive protein (CRP) are consistently higher in periodontitis patients compared with healthy controls. Some systemic markers of inflammation discussed in this review are also regarded as predictive markers for cardiovascular diseases. Therefore changes in these markers in periodontitis may be part of the explanation why periodontitis is associated with cardiovascular diseases and/or cerebrovascular events in epidemiological studies. It is hypothesized that possibly daily episodes of a bacteremia originating from the periodontal lesion are the cause of the changes in systemic markers in periodontitis; the overall size of periodontal lesions in the untreated severe patient may amount to 1500-2000 mm2.</p>","PeriodicalId":75517,"journal":{"name":"Annals of the Royal Australasian College of Dental Surgeons","volume":"18 ","pages":"27-9"},"PeriodicalIF":0.0,"publicationDate":"2006-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26863574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Historically, carbamazepine is and remains the gold standard. Many similarities between the pathophysiologic phenomena observed in epilepsy models and neuropathic pain models justify the rationale for the use of anticonvulsants in the management of neuropathic pain disorders. We have evidence that there is a high intensity of Gamma-aminobutyric acid transporters in the trigeminal sensory nuclei, and that Gamma-aminobutyric transporters expression was increased in the spinal trigeminal nucleus of rats after facial carrageenan injections. These are correlated with increased Gamma-aminobutyric acid uptake in the synaptosomal preparation from the spinal trigeminal nucleus of rats that received the injections and can be antagonised with glial uptake inhibitors. We conclude that Gamma-aminobutyric acid uptake inhibitors may prove to be a novel generation of GABAergic drugs for trigeminal neuralgia.</p>","PeriodicalId":75517,"journal":{"name":"Annals of the Royal Australasian College of Dental Surgeons","volume":"17 ","pages":"70-2"},"PeriodicalIF":0.0,"publicationDate":"2004-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25856737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 3D surface scanner Fiore and its software were used to acquire the 3D scans of the faces while 3D Rugle3 and locally-developed software generated the holistic facial averages. 3D facial averages were created from two ethnic groups; European and Japanese and from children with three previous genetic disorders; Williams syndrome, achondroplasia and Sotos syndrome as well as the normal control group. The method included averaging the corresponding depth (z) coordinates of the 3D facial scans. Compared with other face averaging techniques there was not any warping or filling in the spaces by interpolation; however, this facial average lacked colour information. The results showed that as few as 14 faces were sufficient to create an archetypal facial average. In turn this would make it practical to use face averaging as an identification tool in cases where it would be difficult to recruit a larger number of participants. In generating the average, correcting for size differences among faces was shown to adjust the average outlines of the facial features. It is assumed that 3D facial averaging would help in the identification of the ethnic status of persons whose identity may not be known with certainty. In clinical medicine, it would have a great potential for the diagnosis of syndromes with distinctive facial features. The system would also assist in the education of clinicians in the recognition and identification of such syndromes.</p>","PeriodicalId":75517,"journal":{"name":"Annals of the Royal Australasian College of Dental Surgeons","volume":"17 ","pages":"73-9"},"PeriodicalIF":0.0,"publicationDate":"2004-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25856155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
