The aim of this study was to determine the relationship between inter canine width (ICW) and inter alar width (IAW), inter commissural width (ICoW), and inter canthal distance (ICaD) in Bantu population. Materials and Methods: It was a pilot study included all participants who were aged at least 18 years, without a history of orthodontics treatment from Prosthodontics department, Faculty of Dental Medicine, University of Kinshasa. The Ethics committee of the National Center of Research for Dental Sciences in DR Congo approved the study protocol (CNRSB 1504.218). The participants medical records were obtained from the interview and dental examination. Nature of the study was explained with participant information sheet, and an informed consent of all participants was obtained. The inclusion criteria were no missing maxillary and mandibular teeth, no diastema, and no anterior restorations, 18 years old before enrollment in the study. The exclusion criteria were inability to meet the above requirements, pregnancy, and refusal to participate in the study. The inter-canine width (ICW), inter alar width (IAW), inter canthal distance (ICaD) and inter-commissural width (ICoW) of each participant were measured with a digital Vernier caliper (Mitutoyo, UK Ltd.,) (0.01 mm) three times and the average value was recorded. The inter canthal distance (ICaD) was measured without applying pressure by bringing the recording parts of the caliper just in contact with the medial angle. The inter alar width (IAW) was marked with a fine marked pencil on the widest outer surface of the alae of the nose on either side or width. Those two points were measured without applying pressure by bringing the recording parts of the caliper just in contact with the outer surface. The participant was told to stop breathing shortly to avoid any change in shape of the nose. The inter-commissural width (ICoW) was determined by measuring the maxillary lip vermilion from commissure to commissure without the

Background Guided tissue regeneration procedures provide predictable reconstruction of periodontal tissues in the treatment of furcation involvements in animals and huamns. This study was to compare long-term effectiveness of two different types of polylactic acid (PLA) membranes on periodontal regeneration in surgically created class II furcation defects in dogs.Methods Full thickness mucoperiosteal flap was raised on the buccal aspects of the experimental teeth and class II furcation defects having 5 mm vertical dimensions were created on mandibular premolar III and IV on each quadrant. The exposed root surfaces were thoroughly planed and PLA membranes were placed over the experimental defects on both sites. One site received liquid polymer membrane (LPM), and resorbable periodontal mesh (RPM) membranes were applied to the other site. The animals were sacrificed at 7 months after surgery and the specimens were processed for histological evaluation.Results The average length of new attachment formed on the treated roots in both groups ranged from 3. 02 mm to 4. 5 mm. Complete bone filling was observed at the furcation sites. No statistically significant differences were found between two membranes in any of the parameters (P>0. 05).Conclusion This study demonstrates favorable regenerative outcomes by the use of two different types of PLA membranes that could be used as alternatives for guided tissue regeneration (GTR).

Oral lichen planus （OLP） is a chronic inflammatory disease that is frequently detected in oral tissues. The aim of our study was to identify the prevalence of the detection of periodontopathogenic microorganisms （Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola in OLP patients and to compare with this prevalence of periodontopathogenic microorganisms in healthy non-OLP patients. Our study included 27 （18 chronic periodontitis （OLPP） and 9 gingivitis （OLPG）） patients diagnosed with OLP along with 26 （13 chronic periodontitis （HP） and 13 gingivitis （HG）） healthy non-OLP patients. The multiplex polymerase chain reaction （PCR）with subsequent reverse hybridization method （micro-IDent） was used for identifying periodontopathogenic microorganisms present in subgingival plaque samples. The percentages of detection for A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythia and T. denticola in subgingival plaque samples taken from OLP patients （OLPG and OLPP） were 18.5%, 85.1%, 81.4%, 88.8% and 74%, respectively. Meanwhile, in the non-OLP patients （HG and HP）, these values were 7.6%, 50%, 46.1%, 73% and 57.7%, respectively. Thus, comparing the non-OLP groups with the OLP groups, the periodontopathogens＇ percentages of detection in the OLP groups were higher than those in the non-OLP groups. According to our study results, OLP patients have higher levels of infection with A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythia and T. denticola than non-OLP patients. We argue that the high percentages in patients with OLP may help identify the importance of periodontopathoRenic microorganisms in the progress of periodontal diseases of OLP.

导电水凝胶由于其优异的性能,在可穿戴电子皮肤中的应用引起了广泛关注.然而,挑战依然存在,包括其灵敏度低、循环稳定性差、对极端条件的耐受性有限.本研究提出了一种新型基于液态金属的导电水凝胶,采用双交联聚丙烯酸（PAA）基质,结合了“软”配位和“硬”共价交联机制.这种混合交联网络是通过使用瓜尔胶（GG）稳定的镓（Ga）液滴来催化乙烯基二氧化硅纳米粒子（VSNPs）和丙烯酸（AA）的共聚反应而形成的.生成的Ga3+离子与PAA中的羧基相互作用,形成软配位交联,促进了水凝胶的快速凝胶化.VSNPs的加入显著提高了水凝胶的弹性、韧性和低温耐受性,而无需使用甘油.值得注意的是,其固有的可塑性、粘附性和自愈合性能得以保留.作为应变传感材料,该水凝胶具有17.4的高应变系数（GF）、250 ms的响应时间和恢复时间、0.1%的超低检测下限,以及在100%应变下800次循环的出色稳定性.在甘油溶液中短时间（20分钟）的浸泡进一步将其在-18℃下的延伸率提高到2688%,在1325%-1450%应变范围内的GF提高到28.1,工作范围扩大到0-1450%.延长浸泡时间（4小时）还可以改善其保水性和耐高温性能,使该水凝胶成为可持续、高性能可穿戴电子产品的理想传感材料.
