Comparison of hemodynamic changes with general or local anesthesia during dental treatment in pediatric patients: A prospective clinical study.

BACKGROUND AND AIM: Severe hemodynamic fluctuations during dental treatment can trigger highly undesirable physical reactions. A study was made to determine whether the administration of propofol and sevoflurane contributes to the stabilization of hemodynamic parameters during dental treatment in pediatric patients versus the use of local anesthesia alone. MATERIALS AND METHODS: Forty pediatric patients needing dental treatment were assigned to either general anesthesia with local anesthesia (study group [SG]) or local anesthesia alone (control group [CG]). Two percent sevoflurane in oxygen (100% oxygen, 5 L/min) and continuous propofol infusion (target-controlled infusion [TCI], 2 µg/mL) were used as general anesthesia agents in SG; and 2% lidocaine with 1:80,000 adrenaline was used as local anesthesia in both groups. Heart rate, blood pressure and oxygen saturation were measured before starting dental treatment (baseline) and every 10 min during dental treatment. RESULTS: Blood pressure (p < .001), heart rate (p = .021) and oxygen saturation (p = .007) decreased substantially after the administration of general anesthesia. The levels of these parameters subsequently remained low and then recovered at the end of the procedure. On the other hand, the oxygen saturation values remained closer to baseline in SG versus CG. In contrast, the hemodynamic parameters experienced lesser fluctuations in CG than in SG. CONCLUSIONS: General anesthesia affords more favorable cardiovascular parameters during the entire dental treatment in comparison to local anesthesia alone (blood pressure and heart rate decrease significantly and oxygen saturation proves more stable and with values closer to baseline), and allows dental treatment to be performed on healthy, lacking cooperative ability children who otherwise could not be treated with local anesthesia alone. No side effects were observed in either group.

Hemodynamic and ventilatory changes in pediatric patients with special needs: A comparative clinical study.

Background: Very limited data are available on the hemodynamic and ventilatory changes during sedation and general anesthesia using bispectral index (BIS) monitoring in intellectually disabled children. The purpose was to determine the hemodynamic and ventilatory changes after propofol and sevoflurane administration in children with special needs (CSN) versus healthy children (HC) during dental treatment. Material and Methods: Forty pediatric patients needing dental treatment were allocated into two groups: children without systemic disease (healthy children [HC]) and mentally disabled children (children with special needs [CSN]). Sevoflurane in oxygen (100% oxygen, 5 l/min) and continuous propofol infusion (target-controlled infusion [TCI], 2 µg/ml) were used as sedative agents, and 2% lidocaine with 1:80,000 adrenaline was used as local anesthesia in both groups. Heart rate (HR), oxygen saturation (SaO2), respiratory rate (RR), exhaled carbon dioxide (CO2), blood pressure (BP) and bispectral monitoring (BIS) values were recorded during the entire dental treatment procedure. Results: A statistically significant decrease in systolic BP, diastolic BP and RR was observed, with no significant differences between the healthy and disabled groups. In contrast, the HR and BIS values were lower in the CSN group than in the healthy patients (p ≤ 0.05). Conclusions: Patients with special needs had lower HR and BIS values than healthy patients, while BP, SaO2 and exhaled CO2 showed similar results in both groups. Key words:Bispectral index, hemodynamic changes, ventilatory changes, pediatric patients, special needs.

Effect of Photobiomodulation on Atrophic-Erosive Clinical Forms of Oral Lichen Planus: A Systematic Review.

INTRODUCTION: Oral lichen planus is a chronic autoimmune inflammatory disease of unknown origin, characterized by various clinical forms of which the atrophic-erosive causes patients the greatest symptomatology. For this reason, there are different treatments that improve the associated signs and symptoms. One of these therapies is photobiomodulation (PBM), which, although new, has a high level of acceptance in dentistry based on evidence. However, there are inconsistent results in its application against lichen planus. The aim of this review was to evaluate the effect of photobiomodulation and its effectiveness as a therapeutic alternative for atrophic-erosive lesions. MATERIAL AND METHODS: The databases PubMed, Google Scholar and Cochrane Library were searched to identify studies investigating the photobiomodulation treatment in atrophic-erosive lesions of oral lichen planus. A total of 294 articles were identified, published between 2017 and 2022, and then evaluated; 7 articles that met all the inclusion criteria were included in this study. RESULTS: The type of laser light source used in PBM was the diode laser (four cases), the Nd-YAG laser at the same wavelength of 1064 nm (two cases) and the He-Ne laser (one case). The minimum and maximum wavelengths used were 630 nm and 1064 nm, respectively. Most studies used lesions treated with topical corticosteroids as a control group. The follow-up times of the studies were highly variable. CONCLUSIONS: Photobiomodulation is a treatment that competently combats oral lichen planus lesions by improving signs and symptoms, with no known adverse reactions so far, which makes it more beneficial compared to more conventional therapies, such as corticosteroids, for which side effects have been found.

Oral status of older people in medium to long-stay health and social care setting: a systematic review.

BACKGROUND: Older patients who spend long periods hospitalized or those who are in a situation of institutionalization represent a risk group in this regard, as many of them suffer a degree of dependence and need help to perform the basic tasks of personal care. It is therefore important to learn more of the oral health status of this group of patients in order to make a proper assessment of the situation and to develop protocols for its management. The purpose of the study was to conduct a systematic review to ascertain the oral health status of older people patients admitted to institutions or hospitalized for a long period of time. METHODS: a systematic review of the literature published in two different databases (PubMed, Embase and Cochrane Library) was carried out, with 12 different combinations of keywords based on the following selection criteria: studies published in the last 5 years, in English and/or Spanish and/or Portuguese, with samples of ≥30 patients, performed in patients older than 65 years, admitted to any type of institution and/or hospital center for at least 7 days and in which the state of hard and/or soft tissues of the oral cavity were evaluated in some way. The selected articles were subjected to a thorough analysis. RESULTS: The search strategy covered 1.014 articles: 689 from Pubmed and 325 from Cochrane Library. After applying the eligibility criteria, five articles were selected for our review. The level of evidence of the articles was, a sample of 773 patients most of them were women with an average age older than 70 years old. CONCLUSIONS: The oral health of patients aged more than 65 is worse than that of the rest population. Long hospital stays or being institutionalized in a residence makes this group susceptible to a worsening of their oral health status. It is necessary to develop protocols for the oral health care of these patients, accompanied by training programs for the personnel responsible.

Influence of operator's professional experience in the postoperative course after surgical extrac-tion of the impacted lower third molar: A pilot study.

BACKGROUND: Third molars are present in 96.6% of humans, although they do not always erupt completely. Between 9.5% and 73% of them remain impacted. Surgical removal of impacted third molars is the most common practice in oral and maxillofacial surgery. This procedure results in traumatism and, consequently, the postoperative phase will involve symptomatology. It is uncommon to find studies that directly relate postoperative symptomatology and the operator's experience. The aim of this study was to determine the differences regarding postoperative symp-tomatology in patients undergoing the bilateral extraction of lower impacted third molars and according to the operator's experience. MATERIAL AND METHODS: A prospective cohort double-blind study was conducted in 50 healthy patients (100 molar extractions) to whom both lower third molars were removed by two dentists with different degree of professional experience. The extractions were randomly assigned with a split-mouth design. If an operator extracted the lower third molar on one side, the other operator extracted the contralateral one. The variables studied after four days of postoperative period were Pain (EVA scale), Inflammation and Trismus, in addition to intraoperative time and local anesthesia administered. RESULTS: Statistically significant differences were detected in the time of intervention and in trismus, since the most experienced operator always needed less time and caused higher degree of trismus. However, this does not entail more inflammation or pain in patients, so there are no relevant differences between operators with more or less experience (p>0.05). CONCLUSIONS: The postoperative period is more favorable for the most experienced operator, although the results do not vary in a relevant manner between them. Key words:Preemptive analgesia, dental extraction, cyclooxygenases, real-time polymerase chain reaction.

Is YouTube a useful tool for oral care in patients with Parkinson's disease?

INTRODUCTION: To analyze the quality of YouTube videos offering information about oral care in patients with Parkinson's disease (PD). BACKGROUND: Regular oral and dental care is essential for good general health and well-being. In this regard, the motor and/or cognitive problems of people with PD can complicate correct daily hygiene. MATERIALS AND METHODS: A systematic review was made of YouTube videos for the terms "Parkinson's disease," "dental education," "oral care," "dental care," "oral disease," "oral status," and "oral health." The videos were assessed for content, duration, number of viewings, days since upload, and likes and dislikes. The interaction index and viewing rate were also evaluated. Video quality was rated using a 5-point Likert scale based on the global quality score (GQS). RESULTS: The search identified 620 videos, of which 42 were included in the analysis. The sources of the uploads were universities (n = 15), television channels (n = 8), and other sources (n = 19). Significant differences were recorded according to the source of information in terms of the duration of the videos (P = .021), the number of views (P = .025), viewing rate (P = .028), days since upload (P = .018), likes (P = .048), and dislikes (P = 0.008). CONCLUSIONS: GQS is higher for University videos; YouTube videos are an accessible, effective, informative, and educative tool for improving oral quality of life of patients with PD. RELEVANCE TO CLINICAL PRACTICE: YouTube is increasingly used by patients with chronic disorders, for many reasons, including the desire for a second opinion, the search for support, and a wish to increase personal knowledge of the disease. Likewise, there is a growing interest in the search for information about oral care and coping skills.

Evaluation of endovenous sedation using BIS monitoring in dentistry. A systematic review

BACKGROUND: The aim of the present review was evaluate the utility and validity of the Bispectral Index (BIS) in dental treatment carried out under endovenous sedation, and compare its efficacy with clinical sedation scales. MATERIAL AND METHODS: Electronic and manual literature searches were conducted by two independent reviewers for articles published up to April 2017 in several databases, including Medline and Cochrane Library. RESULTS: Sixteen articles met the inclusion criteria. A correlation was identified between BIS and clinical sedation scales. A BIS range between 75 and 84 showed a high probability of corresponding to an Observer's Assessment of Alertness and Sedation Scale (OAA/S) value of 3; a scored 3 on the Ramsay scale corresponds around 85 on the BIS; while BIS values between 57 and 64 corresponded to a University of Michigan Sedation Scale value of 3. BIS monitoring provides continuous measurement of the patient's hypnotic state or state of consciousness, awareness, and recall. It proved impossible to perform an analysis of statistical data drawn from the studies reviewed due to the disparity of inclusion criteria among the works. CONCLUSIONS: BIS for sedation monitoring might make possible to evaluate sedation levels objectively in real time, reducing the dose of the sedative required, increasing safety, and minimizing secondary effects

Effectiveness of the Botulinum Toxin for Treating Sialorrhea in Patients with Parkinson's Disease: A Systematic Review.

The main objective was to assess the efficacy of botulinum toxin-based treatment for sialorrhea in adult patients with Parkinson's disease. The search was performed by using the Medline-PubMed, EMBASE and Cochrane Library databases from January 2000⁻December 2017, in English/Spanish in patients with Parkinson's disease and sialorrhea. The methodological quality of trials was carried out by following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria and the Newcastle⁻Ottawa Scale (NOS). Finally, a total of 21 articles were identified as fulfilling the inclusion criteria. There is no consensus regarding the site of injection of the toxin (single or multiple points), toxin dose or follow-up period. In all cases there was a reduction of sialorrhea. Treatment safety increases with the use of ultrasonography. Effects approximately occur at one week post-injection and for 3⁻5 months. Botulinum toxin is an effective therapeutic strategy or option in treating sialorrhea in adult patients with Parkinson's disease. More studies with a better design, larger samples and a longer follow-up period are required to confirm these data.

YOUTUBE videos on oral care of the organ or hematopoietic stem cell transplant patients.

OBJECTIVE: Video-sharing websites can be a useful platform for disseminating information. The aim of this study was to evaluate information about the oral health care of the organ transplant and hematopoietic stem cell transplant patients available on YouTube™. METHODS: The transversal study evaluated the content of YouTube™ videos. The videos were located by entering key search terms in the YouTube™ search engine-oral care/dental management/organ transplant/hematopoietic stem cell transplant patients. The videos were then classified as useful, misleading, or as personal experiences reported by patients. The following information was registered: the source of the video, content, interaction, and overall quality. RESULTS: A total of 50 videos were reviewed; 16 (33.14%) were classed as useful, 22 (44%) were misleading, and 12 (24%) reported patients' personal experiences. Significant differences were found in overall quality (p = 0.012). When interaction variables were analyzed statistically significant differences were found for the following: "I did not like this video" (p ≤ 0.05) and comments (p ≤ 0.05). CONCLUSIONS: Several videos reviewed information on oral care of organ transplant and hematopoietic stem cell transplant patients but were sometimes difficult to interpret. Nevertheless, YouTube™ is a tool that can help supply information and promote oral health care education among of organ transplant and hematopoietic stem cell transplant patients.

Pyostomatitis vegetans. Report of two cases and review of the literature.

Pyostomatitis vegetans (PV) is a rare benign chronic mucocutaneous pustular disorder of unknown etiology, though it is usually associated with chronic inflammatory disease of the bowel-particularly ulcerative colitis. At the oral level PV manifests as an exophytic lesion with an erythematous perimeter and a creamy-yellow surface presenting a friable covering membrane which easily disintegrates, giving rise to the development of small ulcers or superficial erosions. The histology shows epithelial acanthosis and superficial ulceration. The underlying connective tissue exhibits neutrophil and eosinophil infiltration, with miliary abscesses in some cases. The present study describes 2 cases of PV associated with ulcerative colitis. The differential diagnosis should be established with Neumann type pemphigus vegetans, since in both cases the lesions are clinically similar and the histology reveals an important eosinophil response, acanthosis, and the formation of intraepithelial miliary microabscesses. The treatment of PV focuses on control of the disease. In the event the orofacial lesions persist, topical oral drugs such as corticoids, with additional antibiotherapy, multivitamin complexes, and nutritional supplements, can be provided.
