Abstract
The role of the oral microbiota in the overall health and in systemic diseases has gained more importance in the recent years, mainly due to the systemic effects that are mediated by the chronic inflammation caused by oral diseases, such as periodontitis, through the microbial communities of the mouth. The chronic infection by the human immunodeficiency virus (HIV) interacts at the tissue level (e.g. gut, genital tract, brain) to create reservoirs; the modulation of the gut microbiota by HIV infection is a good example of these interactions. The purpose of the present review is to assess the state of knowledge on the oral microbiota (microbiome, mycobiome and virome) of HIV-infected patients in comparison to that of HIV-negative individuals and to discuss the reciprocal influence of HIV infection and oral microbiota in patients with periodontitis on the potential establishment of a viral gingival reservoir. The influence of different clinical and biological parameters are reviewed including age, immune and viral status, potent antiretroviral therapies, smoking, infection of the airway and viral coinfections, all factors that can modulate the oral microbiota during HIV infection. The analysis of the literature proposed in this review indicates that the comparisons of the available studies are difficult due to their great heterogeneity. However, some important findings emerge: (i) the oral microbiota is less influenced than that of the gut during HIV infection, although some recurrent changes in the microbiome are identified in many studies; (ii) severe immunosuppression is correlated with altered microbiota and potent antiretroviral therapies correct partially these modifications; (iii) periodontitis constitutes a major factor of dysbiosis, which is exacerbated in HIV-infected patients; its pathogenesis can be described as a reciprocal reinforcement of the two conditions, where the local dysbiosis present in the periodontal pocket leads to inflammation, bacterial translocation and destruction of the supporting tissues, which in turn enhances an inflammatory environment that perpetuates the periodontitis cycle. With the objective of curing viral reservoirs of HIV-infected patients in the future years, it appears important to develop further researches aimed at defining whether the inflamed gingiva can serve of viral reservoir in HIV-infected patients with periodontitis.

Abstract
OBJECTIVE To evaluate the efficacy of topical tacrolimus offered on a custom tray to treat desquamative gingivitis (DG). STUDY DESIGN Eighteen patients with symptomatic DG related to oral lichen planus (OLP) or mucous membrane pemphigoid (MMP) were selected, of which 13 completed the study. Periodontal treatment was followed by the fabrication of a custom silicone tray to apply a tacrolimus gel formulation (0.1%). Clinical evaluation (complaint of pain and burning - visual analog scale from 0 to 10; and the presence of erythema, desquamation, vesicle/blister, erosion, ulcer, and bleeding) was performed by the same examiner on day 1, and every 15 days for 90 days. RESULTS Total remission was found in 4 patients (30.76%). Partial remission was found in 69.24% of the patients, classified with an excellent (30.76%), good (30.76%), and regular (7.69%) recovery, respectively. There was a reduction of about 60% in pain and 65% in burning sensation complaints. Wilcoxon test revealed significant differences between pre- and post-treatment pain and burning sensation symptoms (P < .01). CONCLUSION Topical application of 0.1% tacrolimus gel was effective in the treatment of DG in controlling pain and burning sensation, leading to the clinical remission of gingival lesions in patients with OLP and MMP.

Abstract
Focal dermal hypoplasia (FDH), also known as Goltz syndrome, consists of an unusual genodermatosis that affects tissues of ectodermal and mesodermal origin and various organs and systems, especially skin, bones, eyes, and oral cavity. While systemic manifestations of FDH have been well documented, the oral manifestations have not been extensively discussed. We present a 22-year-old female patient with history of FDH that showed a variety of systemic and oral manifestations. FDH was diagnosed at birth based on cutaneous alterations. Extra and intraoral examination showed facial asymmetry, lip and perioral atrophy, upper lip papilloma, malocclusion, enamel hypoplasia, and gingival hyperplasia. Mucosal lesions, periodontal diseases, and malocclusion were treated by oral surgery, periodontal therapy and orthodontic treatment, respectively. Although FDH is an uncommon syndrome, health professionals should be aware of its systemic and oral manifestations to establish an early diagnosis and adequate treatment.

Abstract
Some studies have demonstrated a high prevalence of Candida species in patients with tuberculosis (TB). This is most likely due to long-term antimicrobial therapy. To date, no longitudinal studies addressed the effects of anti-TB treatment on the fungal burden and virulence of Candida spp. This study investigated the prevalence and virulence of Candida spp. in the oral cavity of 30 TB patients at different stages of treatment through a cohort study. These results were compared with those of 60 systemically healthy individuals in a cross-sectional study. Oral rinse samples from TB patients were collected before 45 and after 120 days of treatment. In the control group, the biological samples were collected only once. Candida spp. were identified by restriction fragment length polymorphism (RFLP) assays, and the following virulence factors were studied: phospholipase C and proteinase production, as well as Candida spp. biofilm and hyphae formation. The clinical diagnosis of TB and its treatment time were associated with the greater fungal burden (p < 0.0001), presence of non-albicans Candida (NAC) species (p = 0.0003), and increased virulence factors when compared with the Candida spp. isolated from systemically healthy individuals. The results showed that anti-TB treatment time was responsible for the increased fungal burden and isolation of NAC in TB patients (p = 0.0233). The increased prevalence, quantification, and virulence of Candida spp. isolated from the oral cavity of TB patients highlight the greater risk of oral lesions and cases of systemic dissemination in these patients.

Abstract
BACKGROUND Human immunodeficiency virus-1 (HIV-1) infected people are more likely to develop tuberculosis (TB), being the leading cause of death in HIV-1. Candida spp has emerged as potential pathogenic fungi in patients with HIV and bronchopulmonary diseases. This systematic review summarizes the available data on the occurrence of oral candidiasis (OC) in the HIV-1/pulmonary tuberculosis (pTB) coinfection. METHODS Articles that reported the occurrence of OC in the HIV-1-pTB coinfection were searched in eight databases. Observational studies that evaluated the association between OC and HIV-1-pTB coinfection were selected. The risk of bias was assessed using the meta-analysis of statistics assessment and review instrument (MAStARI) checklist. RESULTS From a total of 1858 records, after application of inclusion and exclusion criteria, six were included in the meta-analysis. Three studies were at low risk, one at moderate risk, and two at high risk of bias. Considerable heterogeneity across the studies was identified. Meta-analyses performed showed no difference in the prevalence of OC between HIV-1 patients with and without pTB coinfection (odds ratio M-H = 1.77; 95% CI = 0.69 to 4.52). CONCLUSION There is no association between OC and HIV-1/pTB coinfection. PROSPERO REGISTRATION NUMBER CRD42019128735.

Abstract
BACKGROUND Juvenile spongiotic gingival hyperplasia (JSGH) is a benign proliferation of non-keratinised stratified squamous epithelium with evident spongiosis, exocytosis leukocytes and dilated vessels with varying numbers of inflammatory cells. Although uncertain, it has been suggested that the epithelial proliferation is probably related to trauma and local irritants. It emerges as a painless erythematous patch or papule with an irregular surface. CASE REPORTS We present a series of eight cases and a literature review of the clinical presentation and treatment approaches for JSGH. This series includes four females and four males with a mean age of 11.6 years, all complaining of injury to the gums. All lesions were painless and not bleeding. One patient associated the lesion with the onset of trauma and another with a previous history of an eruption cyst. Periapical radiographs of the adjacent area did not show any alteration of bone or teeth. Based on these findings, the diagnostic hypotheses were a non-neoplastic proliferative process or a factitious injury. Incisional biopsy was performed and histopathologic diagnosis was conclusive for JSGH. Surgical excision was conducted in three cases, and the other five cases were supported by clinical observation and plaque control in order to prevent gingival recession defects. After a follow-up period of 11 months (mean), no recurrence was observed for surgically treated cases and mild improvement was achieved with periodontal treatment. CONCLUSION This case series illustrates the importance of diagnosis and follow-up of patients with JSGH. A conservative approach consisting of basic periodontal support instead of surgical excision may be indicated because of the risk of aesthetic defects at the involved areas.

Abstract
Candida albicans is the main causative agent of oral lesions in HIV-infected patients and its oral colonization is a potential source of systemic dissemination. Although the high prevalence of lesions in HIV patients can be explained by the immunosuppressive condition, several studies have reported that natural selection can make C. albicans more virulent in this group of patients. Comparisons of the activity of exoenzymes (phospholipase, proteinase and hemolysin) in C. albicans isolated from HIV-infected and uninfected patients have yielded conflicting results. This study aimed, through a systematic review and meta-analysis, to answer the question: "Is the hydrolytic enzymatic activity of C. albicans, isolated from the oral cavity, different in individuals infected and not infected with HIV?" The question was addressed using the PECO framework: P (Population): children and adults, E (Exposure): HIV infection, C (Comparator): non-HIV-infected patients; O (Outcomes): exoenzymes activity i.e. phospholipase, proteinase and hemolysin. We conducted a systematic search on Pubmed, Embase, Scopus, Livivo, Lilacs, Web of Science, and Science Direct databases, and Google Scholar. The MAStARI tool was used to evaluate the risk of bias in the selected studies. From 2259 studies, 19 were included in this review and 11 comprised the meta-analysis. The activity of phospholipase (M-H = 0.15; Z = 2,76; p = 0.0006) and hemolysin exoenzymes (M-H = 0.07; z = 1,94; p = 0.05) was higher in C. albicans isolated from the oral cavity of HIV-infected patients, whereas the levels of protease activity were not different compared with non-HIV-infected individuals. This study showed a higher phospholipase and hemolysin activity in C. albicans isolates from the oral cavity of HIV-infected patients.

Abstract
OBJECTIVE To evaluate a pilocarpine spray as a treatment for xerostomia in patients treated with radiotherapy (RT) for head and neck cancer (HNC). METHODS This was a placebo-controlled, double-blind, crossover clinical trial of patients complaining of dry mouth after RT for HNC. Forty patients were randomly assigned to either placebo or pilocarpine (1.54%) spray and instructed to use three times a day for 3 months. After 1-month washout period, patients were crossed over to receive placebo or pilocarpine. The assessments were salivary flow (Stimulated Whole Saliva Flow - SWSF), xerostomia (Xerostomia Inventory - XI), and quality of life (QoL/Oral Health Impact Profile - OHIP-14), assessed at baseline, 1 hr (only SWSF), and at 1, 2, and 3 months of treatment. RESULTS Posttreatment SWFS was not statistically different between pilocarpine and placebo regardless of the treatment sequence (paired T test; p > .05), except for the SWFS rates at 2 months after therapy. When comparing pilocarpine with placebo in the time points, there was no significant difference (p > .05) for QoL or XI. Significant differences in improvement in QoL and xerostomia experience appeared along time for pilocarpine group. CONCLUSION The topical application of pilocarpine spray tested was similar to placebo on SWSF assessments in patients treated with RT for HNC.

Abstract
OBJECTIVES Oral lichen planus (OLP) and oral lichenoid lesions (OLL) are chronic inflammatory diseases whose symptoms can impair patient's quality of life (QoL). Psychological factors seem to play an important role in these diseases. This study aimed to determine the impact of oral health and anxiety levels on the QoL of patients with OLP and OLL. PATIENTS AND METHODS This was a cross-sectional study composed of OLP and OLL patients and a control group matched by age and sex with no autoimmune/inflammatory or malignant oral lesions. Anxiety levels and oral health impact on QoL were assessed using the Hamilton Anxiety Scale (HAM-A) and the Oral Health Impact Profile-14 (OHIP-14), respectively. The instruments were filled through personal interview before starting the treatment for oral lesions. RESULTS A total of 87 patients diagnosed with OLP (n = 45) and OLL (n = 42), and 87 controls were included in the study. Statistical differences were observed for the psychic and somatic anxiety dimensions between severities of diseases. Patients with OLP or OLL had higher scores for the OHIP-14 dimensions physiological discomfort and social limitation compared with controls. In addition, higher scores for physical pain, physical disability, social disability, and handicap were detected among patients with greater severity. CONCLUSION Greater severity of OLP and OLL seems to be associated with increased levels of anxiety, higher scores of oral health impact profile, and decreased QoL. CLINICAL RELEVANCE Patients with severe OLP/OLL may benefit from additional therapeutic treatments, such as psychological and/or psychiatric management, concomitant to treatment specific to oral lesions.

Abstract
PURPOSE Florid cemento-osseous dysplasia (COD) is a well-described condition that occurs predominantly in black women. The lesion is usually asymptomatic, but in severe cases, symptoms can occur in association with focal expansion due to infection. The safety of dental procedures that involve areas with florid COD has been little discussed. Therefore, the present study aims to emphasise the importance of nonsurgical periodontal treatment in patients with periodontal diseases and COD. MATERIALS AND METHODS Four thousand five hundred panoramic radiographs from the image bank of the School of Dentistry of Ribeirão Preto were clinically and radiographically evaluated. RESULTS Eleven patients had images compatible with florid COD. Eight patients were asymptomatic and three symptomatic. All patients were diagnosed with chronic periodontitis (CP) and their panoramic radiographs showed mixed radiopaque and radiolucent images in the alveolar bone. In symptomatic patients, besides the clinical signs of CP, exposed bone with severe suppuration occurred in the posterior region of the mandible. CONCLUSIONS The maintenance of systemic and oral health is mandatory to prevent secondary infections, and knowledge about the interface between different dental specialties and florid COD management may prevent erroneous decisions and ensure patient safety, taking into account the dental treatment that can be performed without further complications.

Abstract
Sjögren's syndrome (SS) is a systemic chronic autoimmune disorder affecting the lacrimal and salivary glands. SS may manifest as primary SS (pSS) or secondary SS (sSS), the latter occurring in the context of another autoimmune disorder. In both cases, the dry eyes and mouth affect the patient's quality of life. Late complications may include blindness, dental tissue destruction, oral candidiasis and lymphoma. This paper reports two cases of SS, each of them presenting unusual oral nodular lesion diagnosed as relapsed MALT lymphoma and mucocele. The importance of the diagnosis, treatment and management of the oral lesions by a dentist during the care of SS patients is emphasized, as the oral manifestations of SS may compromise the patient's quality of life.

Abstract
The etiopathogenesis of oral lichen planus (OLP) is still not fully elucidated, and it is believed that its development could involve a neuro-immune-endocrine profile. This systematic review investigated the relationship between cytokines, cortisol, and nitric oxide (NO) in the saliva of OLP patients. An electronic search was conducted in Pubmed/Medline, Scopus, LIVIVO, and Web of Science databases with no restriction of language to identify studies published up to December 2017. Data extraction was performed using the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. A total of 140 articles were retrieved, and 32 articles fulfilled the inclusion criteria (cytokines = 17; cortisol = 9; NO = 6). The most studied cytokines in the saliva of OLP patients were interleukins IL-4, IL-6, IL-8, IFN-ү, and TNF-α, which were higher in OLP patients than in healthy controls (HC). Salivary cortisol was found to be higher in OLP than in HC in most (55.5%) of the selected studies, and all studies related to NO found higher levels of this marker in OLP than in HC. Despite controversial results, our review suggests that OLP patients have an increased inflammatory response, as indicated by the proinflammatory profile of salivary cytokines. In addition, we conclude that salivary cytokine and NO measurements may have significant diagnostic and prognostic potential for monitoring disease activity and therapeutic responses in OLP.

Abstract
The majority of HIV-infected patients develop Candida spp-associated clinical oral lesions. Studies have shown that asymptomatic oral colonization of Candida spp may lead to oral lesions or become a source of disseminated infections. The aim of this study was to verify the effects of periodontal conditions on Candida spp prevalence and Candida spp carriage in the oral cavity of HIV-infected patients compared to non-infected patients. Twenty-five patients not infected with HIV and 48 HIV-infected patients were classified according to periodontal conditions as being periodontal healthy or with periodontal disease. Candida spp carriage and classification were performed in oral rinse samples. Viral load and CD4+ T lymphocyte (CD4+L) counts were performed in blood samples from HIV-infected patients. No differences in Candida spp prevalence related to HIV status or periodontal condition were detected. However, Candida spp carriage was increased in periodontally affected HIV-infected patients when compared to periodontally healthy HIV-infected patients (p= 0.04). Periodontally healthy HIV-infected patients presented Candida spp carriage in similar levels as healthy or periodontally affected non-HIV-infected patients. Candida spp carriage was correlated with CD4+L counting in HIV-infected patients. We concluded that periodontal disease is associated with increased Candida spp carriage in HIV-infected patients and may be a predisposing factor to clinical manifestations of candidiasis.

Abstract
Patients with bisphosphonate-related osteonecrosis of the jaws (BRONJ) who received intravenous or oral bisphosphonates (BP) were selected for determination of their bone microarchitecture as a risk predictor of BRONJ development. The diagnosis of BRONJ was made based on clinical and radiographic findings. The control group consisted of healthy patients. All patients underwent quantitative and qualitative ultrasound measurements of bone at the hand phalanges carried out using the DBM Sonic BP. Ultrasound bone profile index (UBPI), amplitude-dependent speed of sound (AD-SoS), bone biophysics profile (BBP), and bone transmission time (BTT) were measured. The BRONJ group consisted of 17 patients (62 ± 4.24; range: 45-82); 10 (58.8%) were male and seven (41.1%) were female, of whom 11 (64.7%) suffered from multiple myeloma, three (17.6%) from osteoporosis, one (5.8%) from prostate cancer, one (5.8%) from kidney cancer, and one (5.8%) from leukemia. Fourteen (82.3%) of them received intravenous BP whereas three (17.6%) received oral BP. Nine (9/17; 52.9%) patients developed bone exposure: two in the maxilla and seven in the mandible. Regarding quantitative parameters, Ad-SoS was low in the BRONJ group, but not significant. The UBPI score was significantly reduced in BRONJ patients with exposed bone when compared to controls (0.47 ± 0.12 vs. 0.70 ± 0.15; p = 0.004). The present study demonstrated that quantitative ultrasound was able to show bone microarchitecture alterations in BRONJ patients, and suggests that these analyses may be an important tool for early detection of bone degeneration associated with BRONJ.

Abstract
Considering the changes antiretroviral therapy (ART) has brought to the treatment of HIV infection, the current clinical and laboratory profiles of HIV/AIDS individuals referred to oral health centers are crucially important in instructing dentists about the oral health management of these patients. The aim of the present study was to determine the clinical and laboratory profiles of HIV-infected individuals referred to a clinic for patients with special needs between 2005 and 2012 by retrospectively analyzing their dental records. A total of 97 records of HIV patients referred to the School of Dentistry of Ribeirão Preto, Universidade de São Paulo - USP, were analyzed. The Mann-Whitney test was used to determine the associations between mean CD4+ counts, mean viral load, and the presence of HIV-related oral lesions (HIV-OL). Most of the patients were male, and their mean age was 38.3 years. Eighty-nine (92%) patients were on regular ART, 77 (79.4%) had a CD4+ count higher than 200 cells/mm3, and 63 (64.9%) had an undetectable viral load. Twenty patients (20.6%) presented with some HIV-OL, including pseudomembranous and/or erythematous candidiasis and angular cheilitis, which were correlated with a low CD4+ count and with an undetectable viral load (p < 0.05). Among the branches of dentistry, periodontics, followed by surgery and restorative dentistry, was the most sought-after specialty, and no intercurrent events were observed during the dental treatment. It may be concluded that there are no restrictions on the dental treatment of patients on regular ART, It is important, though, that the treatment be based on local characteristics and on the prevention of oral diseases.

Abstract
Atg16L1 mediates the cellular degradative process of autophagy and is considered a critical regulator of inflammation based on its genetic association with inflammatory bowel disease. Here we find that Atg16L1 deficiency leads to an exacerbated graft-versus-host disease (GVHD) in a mouse model of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Atg16L1-deficient allo-HSCT recipients with GVHD displayed increased T cell proliferation due to increased dendritic cell (DC) numbers and costimulatory molecule expression. Reduced autophagy within DCs was associated with lysosomal abnormalities and decreased amounts of A20, a negative regulator of DC activation. These results broaden the function of Atg16L1 and the autophagy pathway to include a role in limiting a DC-mediated response during inflammatory disease, such as GVHD.

Abstract
OBJECTIVE To evaluate the effects of the levels of glycemic control on the frequency of clinical complications following invasive dental treatments in type 2 diabetic patients and suggest appropriate levels of fasting blood glucose and glycated hemoglobin considered to be safe to avoid these complications. METHOD Type 2 diabetic patients and non-diabetic patients were selected and divided into three groups. Group I consisted of 13 type 2 diabetic patients with adequate glycemic control (fasting blood glucose levels <140 mg/dl and glycated hemoglobin (HbA1c) levels <7%). Group II consisted of 15 type 2 diabetic patients with inadequate glycemic control (fasting blood glucose levels >140 mg/dl and HbA1c levels >7%). Group III consisted of 18 non-diabetic patients (no symptoms and fasting blood glucose levels <100 mg/dl). The levels of fasting blood glucose, glycated HbA1c, and fingerstick capillary glycemia were evaluated in diabetic patients prior to performing dental procedures. Seven days after the dental procedure, the frequency of clinical complications (surgery site infections and systemic infections) was examined and compared between the three study groups. In addition, correlations between the occurrence of these outcomes and the glycemic control of diabetes mellitus were evaluated. RESULTS The frequency of clinical outcomes was low (4/43; 8.6%), and no significant differences between the outcome frequencies of the various study groups were observed (p>0.05). However, a significant association was observed between clinical complications and dental extractions (p = 0.02). CONCLUSIONS Because of the low frequency of clinical outcomes, it was not possible to determine whether fasting blood glucose or glycated HbA1c levels are important for these clinical outcomes.

Abstract
INTRODUCTION: This study evaluated whether leprosy reactions could be associated with oral infection. METHODS: Leprosy patients (n = 38) with (Group I) and without (Group II) oral infections were selected. Reactions were identified from the clinical and histopathological features associated with serum C-reactive protein (CRP) and10kDa interferon-gamma-induced protein (IP-10) levels, determined before and after elimination of the foci of infection. RESULTS: Group I presented more reactions than group II did, and improvement of the reactions after dental treatment. Serum CRP and IP-10 did not differ before and after the dental treatment, but differed between the groups. CONCLUSIONS: Oral infection could be an exacerbating factor in leprosy reactions.

Abstract
The aim of this study was to evaluate the efficacy of a 0.05% clobetasol propionate ointment administered in trays to 22 patients with desquamative gingivitis in a double-blind, crossover, placebo-controlled trial. Patients received container number 1 and were instructed to apply the ointment 3 times a day for 2 weeks, and to reduce the application to once a day in the third week. Next, the patients were then instructed to discontinue the treatment for 2 weeks, and were then given container 2, used in the same way and for the same length of time as container 1. Regarding signs, 17 patients presented some improvement, while 5 experienced worsening with clobetasol propionate. With the placebo, 14 patients presented some improvement, and 8 patients presented worsening. For symptoms, there was complete improvement in 2 patients, partial improvement in 12, no response in 7, and worsening in 1 with clobetasol propionate. With the placebo, there was partial improvement in 8 patients, no response in 12 and worsening in 2. No statistically significant difference was found between clobetasol and placebo (p>0.05). Within the period designed to treat the gingival lesions of the patients, clobetasol propionate did not significantly outperform the placebo.

Abstract
Leishmaniasis is a parasitic disease with diverse clinical manifestations, and considered a public health problem in endemic countries such as Brazil. Mucosal lesions usually involve the upper respiratory tract, with a predilection for nose and larynx. Oral involvement is unusual and in most cases it becomes evident after several years of resolution of the original cutaneous lesions. Oral lesions classically appear as mucosal ulcerations, mainly in the hard or soft palate. This report describes the clinicopathological data of 11 cases of mucocutaneous leishmaniasis with oral manifestations. Two cases of Leishmania (Viannia) braziliensis and one case of Leishmania (Leishmania) amazonensis were confirmed by polymerase chain reaction-restriction fragment length polymorphism or DNA sequencing in mucosal samples.

Abstract
O tratamento das lesões gengivais de doenças vesicobolhosas auto-imunes constitui grande desafio na estomatologia, principalmente pela natureza crônica das lesões. O tratamento sistêmico é necessário no controle das apresentações mais graves; entretanto, quando possível, o tratamento tópico é preferível. Este artigo descreve uma técnica oclusiva para aplicação de corticosteróide tópico que tem demonstrado ser eficaz no controle dessas lesões, sobretudo em pacientes com manifestações exclusivamente gengivais.

Abstract
This study technically assessed the WHO-621 periodontal probe made in Brazil as well as its dimensional and weight stability after sterilization. The following characteristics were measured in one hundred (100) new probes: diameter and linear area of tip sphere and beginning and ending references of its colored band by means of indirect computerized morphometric method, and weight, by means of a digital balance within 0.01 mm precision. Fifty (50) probes underwent one hundred (100) cycles of either steam or heat sterilization. The WHO-621 Trinity probe showed mean values of 0.66 mm in its longitudinal and 0.54 mm in its transversal sphere diameters; 0.40 mm2 in its sphere linear area; 3.56 mm and 5.76 mm for the beginning and ending of the colored band, respectively. Its mean weight was 10.12 g with small variation. Some of the measurements showed significant changes after both sterilization procedures. Neither of the sterilization methods showed to be more advantageous (Student's t-test, p = 0.05).
