Dental Treatment and Quantum Mechanics

In clinical practice, dentists sometimes encounter phenomena that cannot be explained by common medical concepts;for example, patients’ bodily symptoms immediately improved after adjusting a denture that was not even inside their mouth, by extracting an infected tooth, and by bringing medicine close to the body. Although it seems difficult to completely elucidate the mechanism through modern medicine, it can be explained using quantum mechanics if it is assumed that symptoms appear because of the pathological waves emitted by the afflicted area of the body. The quantum, the smallest unit of matter composition, exhibits wave-particle duality. The fact that symptoms can be improved simply by bringing dentures or medicines closer to the body indicates that the waves emitted by dentures or medicine interfere with the pathological waves. Thus, the pathological waves are deformed and lead to a change in symptoms. In this way, quantum theory can explain phenomena that are difficult to elucidate in conventional medicine, which are encountered in daily clinical practice. Using biological reactions, unsolved problems in quantum mechanics, such as measurement problems, can be solved.

Objective and Subjective Dental Treatment Needs among Nursing Home Residents

Objective: The aim of the study was to analyze oral, dental and denture hygiene, and the current treatment needs in nursing home residents. Design: Cross-sectional design. Setting: Nursing homes in Saxony, Germany. Participants and Intervention: Participating dentists recorded the frequency of oral, dental and denture care, dental treatment needs, and the request for treatment in 11,144 nursing home residents by using standardized checklists. Results: Mean age of the residents was 82.5 years, and 74.6% were females. For 54.0% of those examined, nursing staff did care for oral, dental, and denture hygiene. 77.5% of the residents performed oral hygiene more frequently than once daily, 19.8% only once a day, and 2.6% performed oral hygiene less frequent. A need for dental treatment was identified in 64.1% of the residents, of which 34.5% were missing dentures, and 29.7% suffered from dental diseases. 58.3% of the residents not requesting treatment had a clinical need for dental therapy. Objective and subjective need for treatment correlated positively (p < 0.001). Conclusion: Nursing home staff should be aware of the poor oral hygiene and health care conditions in residents. In addition to regular dental check-ups, nursing home residents should be given advice on dental care. Furthermore, dentists and health insurances should develop an action plan to improve oral health of nursing home residents, and to reduce additional costs due to lack of dental care.

Dental Treatment for Dizziness and Joint Mobility Disorder Caused by Harmful Electromagnetic Waves

With the development of an IT (Information Technology) society, the opportunity to use electronic devices, such as cell phones and personal computers, has increased. These electronic devices pro-vide many benefits to society. However, there have been a number of reports of electromagnetic hypersensitivity (EHS) related to the use of electronic devices. The symptoms of EHS may include headaches, fatigue, tinnitus, dizziness, memory loss, irregular heartbeat, and skin trouble. Since the pathogenic mechanism of such conditions is not yet clear, further research is required. This report shows how a subject’s dizziness and joint mobility disorder, caused by electromagnetic waves emitted by electronic devices, were cured by removing an onlay from the patient’s mouth and replacing it with a gold alloy onlay. The result indicates that the subject’s symptoms were caused by EHS. Although the symptoms were improved after the dental treatment, the underlying mechanism of the symptoms and the reason why this treatment is successful remain unclear. Further research is required to clarify these issues.

Two Cases of Parkinson’s Disease for Which Dental Treatment Was Effective

The purpose of this study is to document the improvement observed in two cases of Parkinson’s disease (PD) after dental treatment. The first subject is a man in his 60s with severe Parkinson’s disease;medication has not been very effective in this case. Prior to treatment, he was unable to stand without support due to?rigidity. Just after removing as much of the dental infection as possible, he was able to walk, albeit slowly, and as a result of continuing treatment, one month later, the symptoms had significantly improved. The second subject?is a woman in her 40s, who became aware of joint stiffness seven years ago, and was later diagnosed with PD independently at three hospitals. Her main symptoms were rigidity, knee pain, and speech disorder. The dopamine medication worked well against rigidity, but the symptoms reappeared after the medication stopped working. Her condition was significantly improved just after one tooth with an apical lesion was extracted. Although the underlying mechanism has not been clarified, I hypothesize that, at least in these cases, negative signals that passed through the trigeminal nerve to the midbrain affected predominantly the dopaminergic neurons in the substantia nigra of the midbrain. Removal of the harmful signals from the oral area resulted in normalization of the substantia nigra. Further research should be promoted with dental and medical cooperation.

Dental Treatment with 30% Trichloroacetic Acid in a Patient with Moderate Hemophilia A

We present the case of a 51-year-old moderate hemophiliac with gingival bleeding due to papillary inflammation and adherence in the molar area 47. After dental diagnosis a calculus was removed and 30% trichloroacetic acid was placed by a pressurized applicator for five seconds;the procedure was repeated until the bleeding stopped, then tranexamic acid was placed by a gauze. The patient chewed the gauze for 30 minutes and was discharged after repeating the same procedure for 30 minutes more. We observed how local treatment with trichloroacetic acid combined to tranexamic acid placed on the hemorrhagic site was able to stop the bleeding.

Study on the Treatment of Reusable Care Equipment in Public and Private Dental Practices in the City of Conakry

Introduction: The effective sterilization of reusable instruments in dental care is a crucial issue for public health. The aim of this study was to contribute to improving the processing conditions of reusable care instruments in dental practices in the city of Conakry. Methods: We carried out an observational and cross-sectional study of a descriptive type lasting three months from January to April 2022 in public and private dental practices approved for activities. Results: A total of 48 dental practices were surveyed, including 7 public and 41 private. 91.67% had the trays for instrument sterilization. 77.08% had a sterilization device. The instruments were: cleaned 100%, disinfected 70.83%, sterilized 20.83% and 20.83% reused the instruments without being sterilized. 72.97% sterilized the instruments at the end of the day. 50% of respondents declared that there were six stages of sterilization. According to standard standards, one dental office or 2.70% respected the normal sterilization process and 13.51% respected the duration and temperature. The storage quality was inadequate at 95.83%. 95.83% of dental practices are at high risk of contamination. The difficulties encountered by staff in daily activity during our study were lack of hygienists (87.50%), insufficient material resources (58.33%), and lack of protocol procedure (45.83%). Conclusion: This study allowed us to note shortcomings of dental surgeons in the process of processing reusable care materials.

Awareness of Patients toward Dental Implants as an Alternative Treatment to Replace Missing Teeth in Kinshasa, D. R. Congo

Background: Dental implant is an artificial root inserted in the jawbone, which restores a lost tooth so that it looks, feels, and is fit like a natural tooth. It is considered to be the best treatment option for single or multiple missing teeth. The aim of this study was to assess the awareness of patients about dental implants as an alternative treatment in Congolese patients. Materials and Methods: A cross-sectional study was conducted in two institutions namely, CBCO Bandal and Ngaliema Clinic, from August to December 2017. A total of 450 respondents have participated in the survey. A printed questionnaire comprised of 20 questions in order to evaluate patients dental awareness was used. Gender, level of education, awareness of dental implant and dental implants therapy, sources of information and the expectation about the sources of information were assessed. The collected data were entered in Microsoft Excel 2010 and analyzed by SPSS (IBM SPSS 20.0, Chicago, IL, USA) software. Results: Out of 450 participants, 14.4% were aware of dental implants. The main disadvantage of dental implant was the high cost. When asked about the anchorage, 86% didn’t know where the dental implant was anchored. Ninety-two percent didn’t know for how long an implant last, 6% thought that dental implant last for a lifetime. When patients were asked about the sources of information, the dentist (5%) and media (5.5%) were the main sources of information. The majority of patients (88.4%) would like to get information about dental implants from their dentist. Conclusion: Dentists should be more involved in the promotion of information about dental implants as a treatment modality to replace missing teeth.

Non-Thermal Atmospheric Plasma:Can it Be Taken as a Common Solution for the Surface Treatment of Dental Materials?

This study aimed to evaluate the surface roughness and wetting properties of various dental prosthetic materials after different durations of non-thermal atmospheric plasma（NTAP）treatment.One hundred and sixty discs of titanium（Ti）（n：40）,cobalt chromium（Co-Cr）（n：40）,yttrium stabilized tetragonal zirconia polycrystals（Y-TZP）（n：40）and polymethylmethacrylate（PMMA）（n：40）materials were machined and smoothed with silicon carbide papers.The surface roughness was evaluated in a control group and in groups with different plasma exposure times [1-3-5 s].The average surface roughness（Ra）and contact angle（CA）measurements were recorded via an atomic force microscope（AFM）and tensiometer,respectively.Surface changes were examined with a scanning electron microscope（SEM）.Data were analyzed with two-way analysis of variance（ANOVA）and the Tukey HSD test α=0.05）.According to the results,the NTAP surface treatment significantly affected the roughness and wettability properties（P 〈 0.05）.SEM images reveal that more grooves were present in the NTAP groups.With an increase in the NTAP application time,an apparent increment was observed for Ra,except in the PMMA group,and a remarkable reduction in CA was observed in all groups.It is concluded that the NTAP technology could enhance the roughening and wetting performance of various dental materials.

哺乳期是女性分娩后进入的一个特殊生理时期,身体处于恢复阶段,免疫力尚未恢复至产前水平,同时又承担着哺育婴儿等各种身心压力,容易发生口腔疾病。由于乳汁是新生儿重要的营养来源,产妇使用的任何药物都可能进入乳汁,对新生儿产生不良影响。在接诊哺乳期患者时,口腔医生不仅需要根据产妇的全身情况制定方案,还必须把握正确的治疗时机,掌握哺乳期用药知识才能尽量避免严重不良后果的发生。本文就哺乳期口腔疾病治疗的时机选择、药物使用、麻醉和影像检查安全性以及产妇的家庭口腔保健进行归纳总结,以期为哺乳期口腔疾病的临床治疗提供一定参考。

Root Canal Treatment Outcome and Restorative Condition of Teeth Treated by Undergraduates—A Clinical and Radiographic Evaluation

Background: The aim was to evaluate the nonsurgical Root Canal Treatment (nRCT) outcome, the restorative condition and the relationship between the coronal restoration quality and the outcome of teeth endodontic treated by undergraduates at the University of Caxias do Sul School of Dentistry (UCS-SD), Brazil, between 2019 and 2021. 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).

外伤牙早期固定正畸治疗的研究进展

外伤牙的正畸移动是正畸治疗中较常见的难题。尽管已有大量关于外伤牙正畸治疗的研究,但关于不同牙外伤类型、不同创伤程度的外伤牙正畸治疗的最佳方法与治疗时机尚未达成共识。近年,较多学者认为早期开始正畸治疗可以增加外伤牙治疗的成功率并减少牙根粘连的发生。但也有研究显示,外伤牙正畸治疗后可能会出现牙根吸收、牙髓坏死、牙髓钙化。在开始正畸治疗之前记录牙外伤史,全面评估牙外伤患者正畸治疗的收益与风险,对于制定适当的正畸治疗计划是非常重要的。本文就外伤牙早期固定正畸治疗的研究进展进行了综述,以期为相关临床工作提供参考。

三种不同消毒剂对口腔综合治疗台水路消毒效果的比较

目的比较3种不同消毒剂对口腔综合治疗台水路(DUWLs)的消毒效果。方法选取本院2019年装修后待开诊前7台采用独立水源的综合治疗台,分为4组(3组实验组+1组对照组),实验组分别采用500 mg/L含氯消毒剂(A组2台综合治疗椅)、3%过氧化氢(B组2台综合治疗椅)、60 g/L过氧化氢银离子消毒剂(C组2台综合治疗椅)和净化后市政用水纯水(D组对照组1台综合治疗椅),通过3种不同的消毒剂对DUWLs进行消毒,然后收集各组三用枪和高速手机水样进行细菌培养,比较各组DUWLs消毒前及消毒后即刻、1d、3d、7d细菌菌落总数。结果消毒前DU⁃WLs各组细菌菌落总数均严重超标(均>4500 cfu/mL)。3种消毒剂消毒后即刻和消毒后1 d细菌菌落总数明显下降,低于消毒前及对照组。消毒后3 d,除实验C组外,实验A、B两组细菌菌落总数均超过北京市《口腔综合治疗台水路消毒技术规范(DB11/T 1703-2019)》规定的口腔医疗卫生用水标准。消毒后7 d,A、B、C三组细菌菌落总数均接近或超过消毒前水平。结论500 mg/L含氯消毒剂和3%过氧化氢消毒剂对水路消毒效果维持时间短,长期使用对管路内壁造成不可修复的危害。60g/L过氧化氢银离子消毒剂在控制口腔牙椅水路(DU⁃WLs)细菌落数总数和抑制细菌生长时间方面效果最优。
