Human dental pulp stem/stromal cells in clinical practice

Dental pulp stem/stromal cells(DPSCs)are fibroblast-like,neural crest-derived,and multipotent cells that can differentiate into several lineages.They are relatively easy to isolate from healthy and inflamed pulps,with little ethical concerns and can be successfully cryopreserved and thawed.The therapeutic effects of DPSCs derived from animal or human sources have been extensively studied through in-vitro and in-vivo animal experiments and the findings indicated that DPSCs are effective not only for dental diseases but also for systemic diseases.Understanding that translational research is a critical step through which the fundamental scientific discoveries could be translated into applicable diagnostics and therapeutics that directly benefit humans,several clinical studies were carried out to generate evidence for the efficacy and safety of autogenous or allogeneic human DPSCs(hDPSCs)as a treatment modality for use in cell-based therapy,regenerative medicine/dentistry and tissue engineering.In clinical medicine,hDPSCs were effective for treating acute ischemic stroke and human exfoliated deciduous teeth-conditioned medium(SHED-CM)repaired vascular damage of the corpus cavernous,which is the main cause of erectile dysfunction.Whereas in clinical dentistry,autologous SHED was able to rege-nerate necrotic dental pulp after implantation into injured teeth,and micrografts enriched with autologous hDPSCs and collagen sponge were considered a treatment option for human intrabony defects.In contrast,hDPSCs did not add a significant regenerative effect when they were used for the treatment of post-extraction sockets.Large-scale clinical studies across diverse populations are still lacking to provide robust evidence on the safety and efficacy of hDPSCs as a new treatment option for various human diseases including dental-related problems.

The Dental Absces: Epidemiological, Clinical and Therapeutic Aspects at the Dental Office of the Prefectoral Hospital of Siguiri in 2021 in the Republic of Guinea

Introduction: A dental abscess is a collection of pus located in the tissues surrounding the tooth roots. The aim of this work is to describe the epidemiological, clinical and therapeutic aspects of dental abscess in order to contribute to the management of patients suffering from this pathology at the dental office of the Siguiri Prefectural Hospital. Methods: This was a retrospective descriptive study lasting 2 months carried out on the registers of patients received between October 2017 and October 2020 at the dental office of the Siguiri prefectural hospital. Results: 4690 patient files were identified during the study, of which 546 met our selection criteria, i.e. a frequency of 11.64%. During our study, we found 51.83% female compared to 48.17% male, i.e. a sex ratio of 1.07. 54.21% of our patients resided in rural communes compared to 45.76% for the urban commune. The age group most affected was that of 16 - 25 years old or 33.69%. Swelling, pain and functional discomfort were the reasons for consultation in all patients followed by other associated reasons in 41.21%. The premolar-molar group was the most represented, i.e. 86.70%. 80.04% of our patients presented an acute abscess compared to 19.96% of chronic cases. Antibiotic, analgesic, and mouthwash were prescribed in all patients during the study followed by 96.37% of cases prescription of steroidal anti-inflammatory drugs. 93.04% of causal teeth were extracted followed by 6.78% of cases of conservative treatment in our study. In our study, 80.95% of our patients had a good post-therapeutic outcome. Conclusion: This study highlights the need for prevention and early management of dental abscesses.

Clinical efficacy,bone density,and follow-up in implant and orthodontic treatment for inclined adjacent teeth

BACKGROUND Tooth defects can cause elongation of occlusal teeth,leading to insufficient repair space.The combination of dental implant restoration and orthodontic treatment of oblique adjacent teeth has a significant therapeutic effect.AIM To explore clinical efficacy,bone density,and follow-up of implant and orthodontic treatment for patients with inclined adjacent teeth.METHODS In total,98 patients with oblique adjacent teeth were randomly assigned to implant restoration combined with orthodontic treatment(group A,n=49)or to receive implant restoration alone(group B,n=49).Changes in alveolar ridge bone density and apical bone density were observed before and after treatment in the two groups.Changes in chewing function and language function were compared between the two groups of patients.Follow-up lasted for 12 mo after repair to observe any adverse reactions in the oral cavity.RESULTS The clinical effective rates of group A and group B were 97.96%and 85.71%,respectively,with group A having a higher clinical effective rate than group B.After treatment,the bone density of the alveolar ridge and apical bone in both groups decreased compared to before treatment,while the chewing and language functions improved.The changes in various indicators in group A were more significant.After treatment,the satisfaction rate of group A(97.96%)was higher than that of group B(79.59%).The incidence of adverse reactions in group A(2.04%)was lower than that in group B(24.49%).CONCLUSION The amalgamation of implant restoration and orthodontic treatment for adjacent tilted teeth demonstrates notable clinical efficacy,diminishes alveolar bone resorption,and fosters patient functional rehabilitation while exhibiting negligible adverse reactions.

Medical Emergencies in Dental Clinics: A Survey of 2013 Dentists in China

Objective To investigate the feature and frequency of medical emergencies in dental clinics in China and the Methods A survey study was conducted among 2408 dentists who attended continuing educational courses held by Society of Sedation and Analgesia of Chinese Stomatological Association in 18 cities from December 2015 to December 2018.Demographic information of the dentists and the characteristics of medical emergencies they encountered were collected and analyzed.The associated demographic features for dentist experiencing medical emergencies were analyzed by logistic regression model.Results A total of 2013 dentists provided valid responses and reported 2923 events of medical emergencies in dental clinics.Among them,85.0%reported that they had encountered medical emergencies,and 35.5%had encountered at least twice.Syncope(35.9%)and hypoglycemia(30.3%)were the most common reported medical emergencies.Medical emergencies were most likely to occur during local anesthesia(49.9%),out-patient oral surgery(25.9%),and root canal treatment(11.3%).There were 6 patients(0.2%)died in emergencies.84.0%dentists reported that they had never received training courses about medical emergency management in dentistry other than Basic Life Support.Longer practicing time(10-15 years)(OR=0.59,95%CI:0.41-0.85,P=0.004),working in private dental facilities(OR=1.69,95%CI:1.20-2.38,P=0.003)were associated with an increased risk of experiencing medical emergencies.Conclusion More efforts are needed in prevention,early identification,and timely management of medical emergencies in dental clinics in order to prevent fatal outcomes.The results of this survey are useful information for re-designing emergency training courses for Chinese dentists.

To explore and develop a model to maintain and build upon a dental clinic open for all in developing regions, with a primary focus on India

AIM: To study a service model that enables a clinic to be open to all members of the community, irrespective of their ability to pay.METHODS: Sampling methodology was used to gather information in two phases, with the city of Indore as the target region. In the first phase, dental professionals were surveyed to gather the cost of the facility, land and equipment and the cost of sustaining the practice. In the second phase, the residents of Indore were surveyed to collect information regarding their oral health problems and their expenditure for the same. Assessing the current situation, the questions to answer are related to the issues of dental health care access problems and the resources required, human and financial.RESULTS:(1) People younger than 20 years of age form a large proportion(43%) of the population of the city and also a large proportion(54%) of people who visit dental clinics;(2) Dental caries are commonlyfound in the population younger than 20 years of age and mobile teeth in those older than 50 years of age;(3) Dental caries and mobile teeth are almost equally found in people of the age group 20-50 years old;(4) A significantly large proportion of those older than 50 years old have had all their teeth extracted; and(5) A significantly large proportion of the 20-30 years of age group has had no teeth extracted.CONCLUSION: The model which we propose works well for low income patients; however, it places a lot of extra burden on the higher income group. A lot of effort can be put into generating revenue from other sources, including events and donations.

Stress Sensitivity and Signs of Anxiety or Depression among First Year Clinical Dental and Medical Students

Background: Negative stress symptoms are reported in the literature among clinical dental and medical students and can include signs of anxiety or depression. However, very little has been researched about existing psychological preconditions of these students that could make them more vulnerable to negative stress symptoms. Objective: The aims were to explore first year clinical dental and medical students’ experiences of stress intensity, stress sensitivity and signs of anxiety or depression. Gender was also explored as a possible predictor of these psychosocial phenomena. Methods: First year clinical students at Aarhus University dental (n = 49) and medical schools (n = 59) were recruited to fill out a 45-item questionnaire that comprised demographics and three scales: Cohens Perceived Personal Stress (PPS-10), Stress Sensitivity Inventory (SSI) and Depression Anxiety & Stress Scale (DASS-21). Groups and genders were compared by frequency and using association statistics, bivariate odds ratios, nominal logistic regression and ANOVA. Results: Stress intensity perceptions were moderate to high for many. Dental students scored higher than medical students on all mean test scores. In general, women showed higher levels of stress than men. Dental students scored significantly higher than medical students on Depression, Anxiety and Chronic Stress with ANOVA tests. However, when gender, age and medical or dental student status were added into a logistic regression analysis in which high stress sensitivity was the main dependent variable, only high scores in perceived stress intensity and signs of depression and anxiety showed significant main effects. Conclusion: Present study confirmed the literature that reports high degrees of stress among dental and medical students. But more importantly, Stress Sensitivity Inventory appeared to be a reliable and excellent predictor of high perceived stress and signs of depression and anxiety. It can be useful to detect and prevent student psychosocial dysfunction in clinical learning environments. An important challenge for medical and dental educational institutions is to provide specific student emotional support as early as needed as well as to consider appropriate stress prevention curriculum reforms.

Influence of pontic design of anterior fixed dental prosthesis on speech: A clinical case study

BACKGROUND The pontic design of fixed dental prostheses(FDPs)is strongly associated with the phonetic function,and the phonetic function of anterior FDPs with different pontic designs remains understudied.AIM To investigate the immediate and short-term influence of pontic design of anterior FDPs on Chinese speech in a clinical case using objective acoustic analysis.METHODS Two FDPs with two types of pontic design(saddle pontic and modified ridge lap pontic)were fabricated for one patient with maxillary anterior teeth missing.The acoustic analysis of patient’s articulation was conducted immediately after wearing the FDPs and 1 wk after wearing these FDPs.RESULTS The effect of FDP on Chinese vowels(/a/,/o/,/e/,/i/,/u/,and/ü/)was insignificant,because the recovery of vowel distortion occurred within 1 wk for both FDPs.Three(/f/,/s/,and/sh/)of eight Chinese fricative consonants were found to have obvious distortions,and the/s/sound distortion last for more than 1 wk for the patient wearing FDP with modified ridge lap pontic design.CONCLUSION The influence of anterior FDP on articulation of Chinese vowels is insignificant,while the articulation of Chinese fricative consonants is more susceptible.When fabricating anterior FDPs for patients with speech related professions,saddle pontic design can be an alternative option compared with modified ridge lap pontic design.
