Oral microbiota: Discovering and facing the new associations with systemic diseases
No full textThe economic crisis of the first decades of the 2000s had serious repercussions on the economy of individual countries, producing a gradual impoverishment of populations. The reduction in financial resources has significantly reduced citizens’ access to care, forcing them to abandon preventive medicine treatments and check-ups. The health of the oral cavity, which had long been considered of secondary importance when compared with systemic pathologies whose course can be potentially fatal for the patient, has therefore been strongly neglected. In recent years, however, new mechanisms of etiology of systemic diseases have been studied with the aim of evaluating some aspects still unknown. The microbiota, whose interest has grown considerably in the national scientific community, was immediately considered as a key factor in the pathogenesis of some disorders. These analyses have also benefited from numerous advances in the field of crop and molecular diagnostics in the microbiological field. Although pioneering studies have focused on the microbiota of the gastro-intestinal system, subsequent evidence has also been drawn from various studies conducted on the oral microbiota. What emerged is that oral microbiota dysbiosis has been associated with numerous systemic diseases. Therefore, the purpose of this Special Issue is to encourage scientific research on the topic of the relationship between the oral microbiota and systemic diseases, also inviting the use of new techniques for culture and molecular diagnosis. Particular attention will be given to original works in vivo and to literature reviews provided they are carried out with a systematic approach and, if possible, supported by additional quantitative analyses

Personalized dentistry: Approaching a new way for diagnosis and treatment of oral diseases
No full textFor years, it has been thought that the field of dentistry was referring exclusively to some diseases that strictly affect the oral cavity. Dental caries, periodontal disease, and pathologies associated with their worsening were considered almost the only interest in scientific research in dentistry. Recent studies have begun to shed light on the effect of the oral microbiota on general health and on the crucial role of dentistry in its maintenance. In this way, we came to understand that the bacterial populations that make up the oral microbiota can vary profoundly between individuals and that contribute in a fundamental way to outlining the so-called "oral signature". This characteristic is called into question to evaluate the susceptibility, or lack thereof, of the subject to the contraction of a wide range of pathologies, apparently not connected with oral health. From this evidence, it will also be possible to study therapeutic approaches aimed at the eradication of species considered at risk or colonization with species considered protective; thus, giving life to so-called "personalized dentistry". Therefore, this Special Issue is aimed at spreading the scientific knowledge over the current limits in terms of new molecular and culturomic approaches towards the diagnosis of oral microbiota and the treatment techniques of eventually associated systemic diseases. In vivo studies and systematic literature reviews with quantitative analysis of results, when possible, will be given a high priority
Effect of transcutaneous electrical nerve stimulation on pain, edema, and trismus after surgical removal of impacted third molars: a split-mouth randomized clinical trial
No full textBackground: The transcutaneous electrical nerve stimulation (TENS) stimulus inhibits the activity of nociceptive neurons of the central nervous system. Pain relief is achieved by increasing the pulse amplitude of TENS to induce a non-painful paranesthesia beneath the electrodes. This study aimed to assess the effect of TENS on acute pain, edema, and trismus after surgical removal of impacted third molars. Material and Methods: This randomized, double blind, split-mouth clinical trial was conducted on 37 patients with bilaterally impacted mandibular third molars. The angle and body of mandible at the site of surgery in one randomly selected quadrant underwent TENS immediately after surgery (50 Hz, 100-μs short pulse, 15 minutes for 6 days). The TENS stimulator device was used in off mode for the placebo quadrant. The pain score (primary outcome) was measured for 7 days postoperatively, and edema and trismus (secondary outcomes) were assessed at 2, 4 and 7 days, postoperatively. The results were analyzed by repeated measures ANOVA using R software (alpha=0.05). Results: The overall mean pain score was significantly lower in the TENS than the placebo group (P<0.05). The number of taken analgesics in the first 3 days was significantly lower in the TENS group (P<0.001). Postoperative edema in the TENS group was lower than the placebo group but only the difference was not statistically significant (P>.05). The inter-incisal distance, as an index to assess trismus, was not significantly different between the two group at day 2, but it was significantly higher in the TENS group after the second day (P<0.001). Conclusions: TENS effectively decreased pain and trismus following impacted third molar surgery, and may be recommended as a non-pharmaceutical method to relieve postoperative symptoms
Correlation of radiomorphometric indices of the mandible and mandibular angle fractures
No full textThis study assessed the correlation of radiomorphometric indices of the mandible and mandibular angle fractures (MAFs) in an Iranian population. This retrospective study was conducted on 3D computed tomography (CT) scans of 118 patients between 18 to 60 years. The images were divided into two groups with MAFs and other types of mandibular fractures (non-MAF). The gonial angle, ramus height, condylar neck width, minimum ramus width, and mandibular length were all measured using MARCO PACS software. Age, gender, and presence and eruption status of third molar at the fracture side were all recorded. The correlation between these parameters and MAF was analyzed using R software (alpha = 0.05). Of all patients, 41 samples had MAF. The two groups were not significantly different regarding the mean age and gender (P > 0.05). The mean size of gonial angle and ramus height in the MAF group were significantly larger, and smaller than the corresponding values in the non-MAF group, respectively (P < 0.001). The median minimum ramus width in the MAF group was significantly smaller than that in the non-MAF group (P = 0.001). Patients with a large gonial angle had 6.6 times higher odds of MAF compared with other fracture types (P = 0.046). Condylar neck width, mandibular length, and erupted third molars had no significant correlation with type of fracture. Presence of impacted third molar increased the odds of MAF by 5.55 times.Patients with a large gonial angle, short ramus height, minimum ramus width, and impacted third molar are more susceptible to MAF. Surgeons can use these indices to predict the risk of MAF in trauma patients with such facial characteristics, and make a diagnosis by radiographic modalities
Attitude of parents towards oral health and dental treatment of their children during the COVID-19 pandemic
No full textObjective: Increased rate of dental caries among children necessitate regular pediatric dental treatments; however, the COVID-19 pandemic has posed significant challenges for dental visits of children, compromising their oral health. To assess the attitude of parents towards oral health and dental treatment of their children during the COVID-19 pandemic. Material and Methods: 232 eligible parents presenting to the Pediatric Dentistry Department of Qazvin Dental School during March and April 2021 seeking dental care for their children were requested to fill out a questionnaire included data regarding demographic information, child’s dental history, attitude about the COVID-19 and risk of dental treatments. Data were analyzed using independent t-test, one-way ANOVA, and Pearson’s correlation coefficient (alpha=0.05). Results: One-third of the parents reported that fear of contraction of COVID-19 was the reason for not seeking dental care during the pandemic. The majority of the parents stated no change in oral hygiene behavior or consumption of sugary foods during the pandemic. Cancellation of previous dental appointments (P=0.038) and unwillingness to seek dental care at present (P=0.015) were significantly correlated with the susceptibility score. The susceptibility score of the parents was also correlated with their psychological status (P=0.016). A significant correlation was noted between the susceptibility score and attitude as well (r=0.287, P<0.001). Conclusion: High level of concern regarding the COVID-19 prevents parents from seeking dental care for their children. It is imperative to take measures to reassure the parents regarding the safety of dental care for their children during the pandemic to ensure continuation of dental care
Management of special needs patients in dentistry during the SARS-CoV-2 pandemic
No full textSpecial needs patients and their guardians commonly encounter several difficulties due to delayed provision of oral healthcare services in private and public sectors. They are a vulnerable group and are considered highly susceptible to the repercussions of the coronavirus disease-2019 (COVID-19) pandemic. The reduction in the availability of operating rooms and the inability to manage routine visits highlight the need to redesign the doctor-patient and dentist-patient relationship for this category of patients. Diagnostic accuracy and adjustments in drug therapies are crucial elements considering that patients with COVID-19 take drugs that can interfere with those usually prescribed for the control of oral pain and infections. This review aimed to provide some guidelines for the management of patients with special needs in dentistry during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic
Is telephone follow-up really effective in early diagnosis of inflammatory complications after tooth extraction?
No full textTo establish whether telephone follow-up is really able to intercept post-extraction complications and to evaluate the degree of patient satisfaction with this kind of post-surgical monitoring. Six hundred and thirty-eight patients were enrolled and randomly assigned to a test or control group. Test group patients were monitored by telephone follow-up 24 and 72 hours after surgery to investigate the presence of local symptoms that are frequently associated with surgical wound infection and inflammation. Both test and control group patients were examined 7 days at suture removal. Patients with systemic diseases, those in which intra-operative accidents occurred during surgery and those for whom extraction suture was not required, were excluded. At least one complication among alveolar osteitis, alveolar inflammation, alveolar infection and dehiscence involved 15.70% of the patients in the test group and 30.70% of the patients in the control group and telephone follow-up proved to be useful in early identification of anomalies in the post-extraction wound healing process. Comparable results were recorded in all extraction subgroups divided according to the type (surgical and non-surgical) and the number (single and multiple) of extractions performed in the same session. Telephone follow-up showed an 8.60 ± 1.17 (0 to 10 score scale) average acceptance. All cases of alveolar osteitis and infection occurred in patients who underwent antibiotic prophylaxis. Telephone follow-up seems to allow early detection of any possible wound healing complications, it is widely accepted by patients and it could therefore be considered a valid method for wound healing monitoring after tooth extractions, due to its effectiveness, feasibility and low costs
