A typical characteristic of periodontitis is its correlation with other branches of medicine since periodontal disease is often associated with several other illnesses or systemic conditions which exacerbate or predispose the course of the disease. Amongst the most frequent gastroduodenal diseases are those associated with <i><span>Helicobacter pylori</span></i><span> (Hp) infections such as acute gastritis, chronic atrophic gastritis, gastric atrophy, gastritis ulcers, dysplasia, duodenal ulcer, gastric cancer, gastric MALT-lymphoma. Transmission of the microorganism occurs through iatrogenic pathways (faecal-oral, oral-oral) and through food and water ingestion. From this the possible role of the oral cavity becomes evident as a means of transmitting the microorganism and as an extra-gastric reservoir of Hp which develops inside the oral plaque, the main aetiological agent of periodontal disease. Considering that in a patient affected with periodontal disease the oral cavity presents elevated i</span><span>ndices of bacterial plaque in association with infrabony pockets one is</span><span> brought to ask if it might represent a favourable habitat for Hp colonisation. Furthermore, another query that one might pose is whether the presence of Hp in the oral cavity might be the cause of relapse in gastric infections caused by Hp. Consequently, might non-surgical periodontal treatment, in association with an eradicating gastric therapy, foster decontamination of the microor</span><span>ganism in the oral cavity leading to a better prevention of relapse and</span><span> re-infec</span><span>tion of the gastric cavity? Could non-surgical periodontal treatment thus</span><span> mean prevention of gastric diseases brought on by </span><i><span>Helicobacter pylori</span></i><span>? The objective of this study is therefore to evaluate the incidence of periodontal disease and oral Hp infection in patients affected by gastric Hpinfection and to determine the possible benefits of the association of non-surgical periodontal therapy with eradicating gastric therapy compared with treatment that involves just the eradicating gastric therapy in patients who are affected by periodontal disease and Hp infection.</span>展开更多

The aim of this study was to determine the impact of non-surgical periodontal therapy on salivary levels of TIMP-1 among patients with chronic periodontitis in Nigeria. In this experimental study, unstimulated whole saliva (2 mL) was collected from participants in the experimental and control groups, coded (SP1-40 and SH1-40) respectively and assays for salivary TIMP-1as well as clinical measurements such as plaque (PI), probing depths (PD), and CAL were recorded before and 4 weeks after periodontal treatment. Assay was done using Quantikine human TIMP-1 ELISA kit. Data were presented using frequency tables, means and standard deviation. Paired-T Test assessed association between salivary TIMP-1 before and after treatment. Pearson correlation coefficient was used to correlate salivary TIMP-1 levels with clinical parameters of periodontal disease and levels of statistical significance were set at p < 0.05. A total of 80 respondents participated in the study of which 43.80% were females. Age range was 18 - 60 years with a mean of 35.8 ± 12.46 years. Salivary TIMP-1 levels were lower in the case group (13.58 ± 6.53 ng/mL) than the control (15.27 ± 6.10 ng/mL) at baseline but this was not statistically significant (p = 0.13). There was a statistically significant increase in the salivary levels of TIMP-1 in the case group after phase-one periodontal therapy from 13.58 ± 6.53 ng/mL to 17.24 ± 8.44 ng/mL (p = 0.001). Negative correlations were observed between TIMP-1 and clinical parameters of periodontitis. This was not statistically significant. Therefore, TIMP-1 may not be an ideal biomarker for periodontal diagnosis but may be useful in treatment monitoring of the disease.展开更多

Methods Moderate to advanced chronic periodontitis ( CP) was studied in 36 diabetes mellitus (DM) patients classified as 20 with high and fluctuating blood glucose level (DM-H) and 16 with relatively low and stable blood glucose level (DM-L). 28 non-DM CP patients acted as controls (Non-DM). Plaque index (PlI) , gingival index (GI) , bleeding on probing (BOP) , probing depth (PD) and clinical attachment loss (AL) of all patients were recorded at 6 sites on each tooth at the baseline and 1, 3 and 6 months after oral hygiene instruction (OHI), scaling and root planing. Results It was found that the short-term effect of non-surgical periodon-tal procedure had resulted in significant resolution of gingival inflammation and pronounced reduction in pocket depth and gain of attachment loss in both DM and Non-DM CP patients. Conclusion The pilot study suggested that non-surgical periodontal treatment allowed for favorable treatment responses in a group of Chinese diabetic subjects with chronic periodontitis and that their various profiles of blood glucose did not influence the short-term healing response to OHI, scaling and root planning.展开更多

Skeletal C...Class III malocclusion associated with posterior crossbite, anterior open bite pattern with asymmetric occlusion in adults can be a challenging orthodontic problem, especially for the nonsurgical treatment. Skeletal Class III anteroposterior discrepancies in adult patients are generally managed either by surgical-orthodontic treatment or by orthodontic camouflage through dentoalveolar compensation. Although correction with surgery may be the most effective and stable way, many patients refuse surgical treatment plan because of the costs and traumas it may bring. This case report describes the successful use of TADs with expansion auxiliary wire to treat a 24-year-old man with skeletal class III malocclusion, posterior crossbite, anterior open-bite and asymmetric occlusion, mild upper and lower dental spacing and a chief manifestation of anterior crossbite. The patient refused surgery. A treatment plan was formulated consisting of using auxiliary expansion wire to expand the maxillary arch, 8 mm mini-screws between the roots of the mandibular canines and first premolars, preadjusted edgewise brackets to align the teeth, Class III and asymmetric elastics to correct the canines, premolars, and molars relationship and midline deviation, reverse curve of the nickel-titanium wire combined with anterior vertical elastics to intrude molars and correct the anterior open-bite. In this case, without going through surgery, the posterior cross-bite was corrected, and ideal overjet and overbite relationships, midline coincidence and functional occlusion were all achieved. Satisfactory occlusal, functional, esthetic and stable results were obtained.展开更多

The atrophic scars were composed of rolling scars (three depressions, 8 × 4 mm in diameter), ice pick scars and boxcar scar. The patient was treated with chemical peeling (CP) using 20% glycolic acid (GA) (pH 3.2) and subsequent iontophoresis with vitamin C derivative at one month’s interval twice. Remarkable improvement was observed;the rolling scars almost disappeared with traces of hypopigmented macule. However, the ice pick scars and boxcar scar did not improve. CP and subsequent vitamin C iontophoresis can be an alternative non-surgical and non-invasive treatment for rolling scar in acne.展开更多

Herein we report the case of a patient, exhibiting ICR and elaborate the effects of a non-surgical approach in the amelioration of this condition.CASE SUMMARY A 21-year-old female reporting intermittent pain at the upper left side, multiple restorations, no trauma history, and having received orthodontic treatment was studied. Localized erythematous swelling was noted at the buccal interdental papilla between the left maxillary first molar and second premolar. The diseased pulp and tissue in resorption were removed and the root canal system including the defect were sealed using gutta percha/AH Plus and mineral trioxide aggregate(MTA). At the one-year recall, the tooth showed no symptoms and responded normally to percussion and palpation. The surrounding periodontium exhibited a normal color and the probing depth was normal. Radiographic examination showed a restoration of crestal alveolar bone and good adaption to MTA.CONCLUSION Non-surgical root canal treatment in conjunction with resorption defect orthograde repair with MTA was found to be an effective treatment option in the elimination of ICR. Early diagnoses are recommended in order to employ nonsurgical approaches for management of ICR instead of surgical interventions.展开更多

Materials and Methods: Data from the endodontically treated cases were retrieved, and the patients were recalled for a follow-up appointment at the university. The endodontic diagnosis, radiographs, and the presence of definitive restorations were analyzed in the clinical records. During the follow-up appointment, endodontically treated teeth were classified as present or absent. The nRCT was classified as successful (complete or incomplete healing) or failure (uncertain or unsatisfactory healing). Coronal restoration was classified as absent or present. When it was present, it was classified as permanent or temporary, and its quality as adequate or inadequate restoration. The results were presented as percentages. Results: A total of 257 teeth were endodontically treated. The most prevalent diagnosis was Chronic Apical Periodontitis (33.33%) and the most commonly treated teeth were premolars (46.15%). A total of 52 (21%) treated teeth were clinically and radiographically reexamined. The success rate for the nRCT was 98.08%. About 61.54% of this sample had a definitive composite resin restoration. Conclusion: The nRCT success rate was high. Special attention should be given to the presence and quality of the definitive restoration. Clinical Implications: There was no statistically significant impact between the coronal restoration and the nRCT success (P > 0.05).展开更多

文摘BACKGROUND Most physicians consider molars with chronic apical periodontitis(CAP)lesions as contraindications for immediate implant placement.At the patient’s request,we perform immediate implant placement of the mandibular molars with CAP in clinical practice.AIM To retrospectively analyze and compare the 5-year outcomes of immediate implant placement of the mandibular molars with CAP and those without obvious inflammation.METHODS The clinical data of patients with immediate implant placement of the mandibular molars in the Department of Oral and Maxillofacial Surgery,the Affiliated Hospital of Qingdao University,from June 2015 to June 2017 were collected.The patients were divided into CAP(n=52)and no-CAP(n=45)groups.Changes in bone mineral density and bone mass around implants were analyzed 5 years after implant restoration.RESULTS At 5 years after implantation,the peri-implant bone mineral density was 528.2±78.8 Hounsfield unit(HU)in the CAP group and 562.6±82.9 HU in the no-CAP group(P=0.126).Marginal bone resorption around implants did not differ significantly between the two groups,including buccal(P=0.268)or lingual(P=0.526)resorption in the vertical direction or buccal(P=0.428)or lingual(P=0.560)resorption in the horizontal direction.Changes in the peri-implant jump space did not differ significantly between the two groups,including the buccal(P=0.247)or lingual(P=0.604)space in the vertical direction or buccal(P=0.527)or lingual(P=0.707)space in the horizontal direction.The gray value of cone-beam computed tomography measured using Image J software can reflect the bone mineral density.In the CAP area,the gray values of the bone tissue immediately and 5 years after implant placement differed significantly from those of the surrounding bone tissue(P<0.01).CONCLUSION The results of this study suggest that immediate implant placement of the mandibular molars with CAP can achieve satisfactory 5-year clinical results,without significant differences in the complications,survival rate,or bone tissue condition from the no-CAP mandibular molars.
