Evaluation Of The Clinical Effects Of Mini Five Curettage Instrument And Monocycline Hydrochloride In Class Ⅱ Furcation Involvements Treatment

Classâ…¡molar furcation involvement represent one or more of the furcation in multi-root teeth has been bone resorption, but because furcation areas which have not been absorbed by alveolar bone, so that lesions have not yet interlinked with the contralateral, its the most common clinical furcation involvement. The treatment goal is to clear the the plaque and calculus of lesions , so that periodontal pocket elimination or shallow, and create favorable effect of plaque control and maintenance of the anatomical shape, to strive for some of periodontal tissue regeneration. As the furcation region complex anatomy, has brought some difficulties to the treatment, the prognosis is also worse than the single root teeth.Currently the more convention treatment is periodontal flap surgery, including: the apical repositioned flap, coronally repositioned flap, osteoplasty, bone graft procedure and guided tissue regeneration. However, the use of surgical treatment on the one hand will increase the patient's trauma and psychological fear, on the other hand implant materials, due to high cost, but also increased the economic burden of patients, and the surgical success rate and the amount of renewable organizations still to be improved. In recent years, with the continuous development of periodontal operation of equipment and local slow-release drugs in the treatment of periodontitis, non-surgical treatment of Classâ…¡furcation involvements has been gradually concern. For standard Gracey curettes' work side shank shorter and more generous blade, USA Hu-Friedy Company under a special multi-root tooth anatomy, developed the Mini Five-type curettes:â‘ 3mm the lower shank of the lengthened so that more curettes into the deep periodontal pocket, as well as 5mm or deeper below the root surface;â‘¡Cut blade, only half the length of standard Gracey curette, more easy access to a narrow periodontal pockets and furcation;â‘¢Blade thickness ratio standard Gracey curette reduced by 10%, more in-depth subgingival, and the reduction of tissue expansion;â‘£Adhering to the standard Gracey curette uses area-specific characteristics, precise control. Local drug delivery of periodontal pocket, with the characteristics of high concentrations and little systemic side effects, but also to some extent compensate for partial furcation anatomy of the complexity, subgingival plaque difficult to eradicate. Minocycline hydrochloride ointment is a slow-release of periodontal medicine, the main component of minocycline, has the characteristics of a broad spectrum anti-bacterial, anti-bacterial activity of strong, efficient, long-lasting, easy to penetrate, as well as various types of periodontitis-induced bacteria are highly sensitive to, it was regarded as the preferred drug of periodontal disease medicines.Object The aim of this clinical trial was to evaluate the clinical effects of mini five curettage instrument and monocycline hydrochloride in classâ…¡furcation involvements treatment. We hope that the experiment has achieved good results, for the non-surgical treatment of teeth to provide clinical basis, to reduce the trauma and economic burden of patients and achieved good social effects.Method Thirty-two patients with sixty-eight teeth presenting at classâ…¡furcation involvement were recruited. Plaque index(PLI), bleeding index(BI), probing depth(PD), horizontal probing depth(HPD) were recorded at baseline,and 5 weeks after therapy. Following a baseline examination, an ultrasonic subgingival device was performed with every case, than a single episode of scaling and root planing (SRP) was provided using mini five gracey curette and monocycline hydrochloride in the test group, and standard gracey curette in the control group. Result 1 At baseline, there were differences between two groups(P<0.05); 2 The test group, mean PIL,BI,PD,HPD differed significantly(P < 0.01); 3 Treatment achievement ratio of the test group was 86.29%, which was significantly higher than control group 52.94%(P<0.01).Conclusion The results suggest that non-surgical treatment with mini five gracey curettage instrument and monocycline hydrochloride has a significantly better potential in treating classâ…¡furcation involvements. So that more teeth from to avert surgical treatment, to reduce patient trauma and economic burden.
