Stress is a physiological response of the body to stressful life events but may not be when the individual is persistently exposed to the stress trigger, and it negatively affects certain physiological functions, thus triggering psychosomatic diseases. In literature, chronic stress and inadequate coping strategies are found to mediate the risk and development of periodontitis; mechanisms have therefore been proposed to explain the effects of stress on the periodontium. Since stress is a prevalent problem in modern life and given the importance of maintaining oral health, the present literature review aimed to estimate the association between stress and periodontal disease. The research question adopted is the following: “Are psychological stress and periodontal disease related?” The search was conducted in August 2022 and limited to articles in electronic databases from 2017 to 2022 in English, excluding reviews and literature reviews. From the electronic databases, a total of 532 articles were identified and became 306 after reviews and duplicates were removed. An additional bibliographic search was conducted through the same electronic databases, controlled terms and keywords including only systematic reviews, which were previously excluded. Through the bibliography cited in the systematic reviews, an additional 18 articles were identified, with a new total of 324. As a result of reading the title and abstract of these 324 articles, an additional 295 were excluded. Reading the full text of the remaining 29 studies, 2 articles were excluded due to non-adherence to the eligibility criteria. The remaining 27 results were included in our literature review. It has been suggested in the literature that adverse socioeconomic conditions elicit a stress response, which can trigger periodontal inflammation. Most of the 27 articles included in the study confirm and demonstrate a positive association between psychological stress and periodontal disease. Numerous studies have shown the mechanisms through which chronic stress negatively affects periodontal tissues. Therefore, in the light of the results obtained from this review, it is important that oral health professionals, also for general health purposes, consider stress factors among the risk factors of periodontal disease, its severity and decreased efficacy of treatments. It is therefore advisable to act preventively through the interception of chronic stress.

Objective The study evaluated the efficacy of tea tree oil for the treatment of gingivitis. Materials and Methods The tea tree oil was administered in the form of mouthwash and then compared with a mouthwash with chlorhexidine 0.12%. Both treatments were domestic and lasted for 14 days. Patients were chosen according to random criteria, aged between 18 and 60 years, and who showed a clinically evident gingivitis. In clinical evaluation, the following clinical criteria were taken into consideration: gingival index (GI), plaque index (PI), bleeding index (BI), probing depth (PD), the presence of dental dyschromia, and the presence of taste alteration. The subjects were evaluated before (T0) and after the treatment (T1), and the data collected for each patient were recorded on a periodontal chart. Results The comparison showed that tea tree oil offered a better improvement in the evaluation of PI, BOP, and PD; furthermore, it did not cause dental dyschromia and taste alteration. In group A, treated with tea tree oil, PI decreased from 53.25 to 5.50% and BI from 38.41 to 4.22%. In group B, treated with chlorhexidine PI decreased from 47.69 to 2.37% and BI from 32.93 to 6.28%. Instead, the subjects using chlorhexidine 0.12% blamed a distaste for the product that caused a slight taste alteration; 20% of them showed iatrogenic dental dyschromia. Conclusions The collected data showed the efficacy of both treatments. Although further research works will be necessary, this study showed that tea tree oil could be an effective nontoxic substitute for the therapy of gingivitis.

Multiple sclerosis (MS) is an autoimmune disease in which the immune system reacts by damaging the central nervous system, specifically myelin and oligodendrocytes. It is the most debilitating neurological disease among young adults, causing personal, familiar, social, and professional limitations. Multiple sclerosis can cause disturbances in the orofacial district, due to a demyelination process on the nerves of the head and neck district. The aim of this study was to evaluate the oral health status, dysphagia, and quality of life of patients affected by MS. For this study, 101 patients aged between 12 and 70 (47 males, 54 females) affected by MS were selected, and three questionnaires were handed out and anonymously filled in by them: An oral hygiene test, DYMUS (DYsphagia in MUltiple Sclerosis), and IOHIP-14 (Italian version Oral Health Impact Profile). Through the analysis of the questionnaires it was possible to observe pathological conditions, such as gingival inflammation, xerostomia, dysphagia, neuralgia, and dysarthria. Through the analysis it was possible to outline how the roles of a medical team, composed of a dentist, otolaryngologist, and dental hygienist, are fundamental in coping with other medical figures, during the whole development of the diseases, as well as to prevent possible complications.

Objectives The aim of the study was to evaluate the coconut oil pulling efficacy as adjuvant in reducing plaque formation and in treating plaque-induced gingivitis. Materials and Methods A sample of 20 patients was divided into two groups: a study and a control group. In the study group, coconut oil, in form of mouthwash, was administered to a sample of patients affected by gingivitis, aged between 18 and 35. The protocol established a daily application of the product for 30 days, where clinical parameters for plaque formation and gingivitis—plaque index (PI), bleeding index (BI)—will be evaluated during the recalls on a specific periodontal chart. The control group did not associate a coadjuvant to the normal daily oral health procedures and the same clinical parameters were evaluated at t0 and after 30 days (t1). The data were statistically analyzed using Student’s t-test, establishing the significance level as p < 0.05. Results PI and BI decreased in both groups, with a more relevant and significant drop in the study group, from a mean value of PI of 58.0 to 19.3 and a mean value of BI of 33.5 to 5.0. In the control group, the values decreased, respectively, from 53.9 to 29.1 for PI, and from 33.5 to 16.2. Furthermore, no significant side effect was reported during coconut oil pulling therapy. Conclusions The collected data showed significant and promising improvements in reducing plaque formation and gingivitis. However, further researches have to be performed to have more consistent and statistically significant data on larger samples and to fully understand the mechanisms of action and effectiveness.

The focus of this paper is the pediatric dental care of Cleft Lip and Palate (CLP) children and the role of the pediatric dentist in the CLP team. The management of children with cleft lip and palate presents many challenges and a multidisciplinary and prepared team is always required. Affected individuals present a multiplicity of problems: effective management involves a wide range of specialities. The value of a multidisciplinary team is widely known and mentioned in the literature, but very few papers focus on the role and the importance of the pediatric dentist. Therefore, the purpose of this article is to underline the role of the pediatric dentist as a member of the cleft lip and palate team which ranges from prenatal counseling, presurgical prevention and orthopedics, to post-treatment rehabilitation and restoration.
