Abstract
OBJECTIVES To assess the effectiveness of amitriptyline (AMT), and to identify the determinants of the treatment's effectiveness in patients diagnosed with burning mouth syndrome (BMS). BACKGROUND Treatment of BMS is challenging and no established treatment protocol is available. AMT may be an important treatment option, cout not all patients benefit from this drug. Studies assessing factors related to treatment response are valuable in improving decision-making. MATERIALS AND METHODS This case series study examined the medical records of all patients diagnosed with BMS at an oral medicine unit in a university hospital from 2008 to 2022. The patients were divided into responders to AMT and non-responders to AMT. Data on demographic information, comorbidities, medications, types of symptoms and oral subsites affected were collected. Descriptive and bivariate analyses were conducted to assess the association between the independent variables and the outcome, using the Chi-squared test (P < .05). RESULTS Three hundred and fourty-nine patients reported a burning mouth sensation, 50 of them (14.3%) being diagnosed with primary BMS. Of these, 35 were treated with AMT, and 26 (74.2%) responded significantly to AMT. All males responded to AMT, whereas only 67.9% of females responded. The mean dose of AMT among responders was 29.8 ± 12.3 mg, with most patients achieving a response with 25 mg (61.5% of patients), followed by 50 mg (23%). The concomitant use of an anticonvulsant resulted in non-response. CONCLUSIONS AMT may be effective in BMS management for most patients.

Abstract
Ameloblastic carcinoma (AC) is an uncommon malignant odontogenic tumor, with about 200 cases published in the literature. Here, we report a case of AC occurring in the maxilla - at the same anatomical location of an ameloblastoma 8 years earlier. A 23-year-old woman with maxillary swelling of 6-month duration was referred to our service. Extraoral examination revealed a swelling over the right side of the face, lifting her lip and nose. Intraorally, a firm, reddish, nodular swelling involving the right maxilla was observed. Computed tomography showed a hypodense image invading the right maxilla, maxillary sinus, and nasal fossa. An incisional biopsy was performed, followed by histopathologic examination and an immunohistochemical panel, which led to the diagnosis of AC. The lesion was treated with partial maxillectomy followed by immediate rehabilitation. Neither local recurrence of the tumor nor distant metastasis was observed during a 4-year follow-up. AC is a highly malignant lesion which requires aggressive therapy. Its diagnosis should be based on combined clinical, imaging, and pathological manifestations in order to improve diagnostic accuracy.

Abstract
Hyperthyroidism is a common disease, with a prevalence between 0.2% and 0.5%, characterized by an increase in the synthesis and release of thyroid hormones. Management of this condition requires medical intervention to correct the hormonal imbalance and control its clinical manifestations. Methimazole is a thionamide derivative considered among the first-choice treatment options for hyperthyroidism. However, it may cause serious side effects such as neutropenia or agranulocytosis, which, although rare, can lead to death. The clinical manifestations of this complication range from fever, ulcerations in the oral and pharyngeal mucosa, tonsillitis, and lymphadenopathy to hemorrhagic necrosis and septicemia. This report describes the case of a patient with generalized gingival necrosis that was related to the use of methimazole for the treatment of hyperthyroidism.

Abstract
Leucoplasia bucal é uma mancha ou placa predominantemente branca, não-removível por raspagem, que não pode ser caracterizada como nenhuma outra lesão. Seu principal fator de risco é o tabaco. Qualquer região da mucosa pode ser afetada e as lesões apresentam potencial de malignização. Diversas formas de tratamento estão disponíveis, sendo a excisão cirúrgica com bisturi a mais utilizada. Objetivo: realizar uma revisão de literatura a respeito dos tratamentos disponíveis e prognóstico da leucoplasia. Resultados: além da excisão cirúrgica convencional, tratamentos cirúrgicos alternativos como a vaporização da lesão pela aplicação de laser de dióxido de carbono e a criocirurgia vêm se difundindo. Os tratamentos não-cirúrgicos envolvem a aplicação de retinóides, beta-caroteno, bleomicina ou de outros fármacos, relacionados com a terapia fotodinâmica. A escolha do tipo de tratamento a ser empregado se baseia na experiência clínica do profissional, tamanho da lesão e julgamento crítico da relação custo-benefício. Conclusão: a maior experiência clínica e a possibilidade de avaliação microscópica de toda peça cirúrgica favorecem a utilização da remoção cirúrgica convencional. Contudo, é importante destacar que a remoção de toda lesão não descarta a possibilidade de recorrência e de malignização, as quais ocorrem de forma imprevisível, independentemente do tratamento escolhido. Portando, os pacientes com leucoplasia bucal devem ser submetidos a um rígido programa de acompanhamento clínico periódico, favorecendo a identificação precoce da ocorrência de transformação maligna.

Abstract
OBJECTIVE The diagnosis of oral lesions is often challenging for primary healthcare providers, which explains the high number of referrals to specialist care. This favors increases in waiting lines and delays in diagnosis, contributing to high mortality rates from oral cancer. This study aimed to summarize the experience of the EstomatoNet, a telediagnosis program catering to primary care dentists and physicians from southern Brazil. STUDY DESIGN This exploratory study included all queries received by EstomatoNet from June 2015 to December 2016. Health providers (71 dentists and 18 physicians from primary care) submitted requests including clinical information and photographs of oral lesions by means of a cloud-based platform. Specialized oral medicine teleconsultants received the data, conveyed a diagnostic hypothesis, and conveyed management recommendations. RESULTS Actinic cheilitis (n = 41, 15.8%), squamous cell carcinoma (n = 22, 8.5%), and inflammatory hyperplasia (21, 8.1%) were the most frequent diagnoses. Teleconsultants recommended referral to specialists in 42.9% of the cases, total biopsy in 23.6%, and follow-up in 16.2%. After the EstomatoNet use, the intention to refer the patients to face-to-face consultation reduced from 96.9% to 35.1%. CONCLUSION Telediagnosis for oral lesions is feasible and has potential to improve the quality of primary health care by bridging the gap between primary and specialized health care.

Abstract
The aim of the present study was to evaluate the effect of 15% alcohol dependence on ligature-induced alveolar bone loss and TNF-α secretion in Wistar rats. Thirty-three male Wistar rats aged 45-60 days (mean weight=253 g) were randomly allocated test or control groups. Test group (n=18) received 15% alcohol as liquid intake and control group (n=15) received water during the experimental period. TNF-α was analyzed by ELISA assay in 11 animals per group. After 14 days of alcohol/water intake, alcohol dependency was assessed and silk ligatures were placed around the left second upper molars. Ligature presence and body weight were checked weekly. After 40 days, animals were sacrificed and the maxillae were defleshed for morphometric analysis using standardized images. All animals in the test group displayed signs of alcohol dependency at day 14. No statistically significant differences in final body weight (334.83±21.38 vs. 322.48±30.65 g, p=0.20) were observed between groups. In relation to alveolar bone loss, no statistically significant difference was observed among test and control groups both for ligated teeth (0.76±0.06 vs. 0.74±0.10 mm, p=0.60) and unligated teeth (0.41±0.16 vs. 0.35±0.05 mm, p=0.22). The TNF-α secretion also did not display statistically significant differences between test and control groups (10.78±1.84 vs. 12.13±2.11 pg/mL, p=0.12). It may be concluded that 15% alcohol dependency was not capable to alter alveolar bone loss and TNF-α secretion in Wistar rats.

Abstract
OBJECTIVES The aim of this study was to characterize the histomorphometric features of subgemmal neurogenous plaques (SNPs) to better understand their relationship to surrounding microanatomy included in the tissue biopsy samples of the tongue. STUDY DESIGN A 12-year retrospective study on the files of 3 oral pathology centers yielded 28 SNPs. Hematoxylin and eosin-stained sections were used for histologic analysis, and immunohistochemical staining for S100 protein was performed to better characterize the neural structures. Slides were scanned and histomorphometric analysis carried out using ImageScope software. RESULTS Twenty-one women (75%) and 6 men (21.4%) comprised the sample (mean age 46.4 and 49 years, respectively). Twenty cases (71.4%) were juxtaposed to the tongue epithelium and 16 cases (57.1%) were associated with lymphoid tissue. The mean area of the SNPs was 0.160 mm2, and the mean distance to the overlying epithelium was 0.312 mm. CONCLUSIONS SNPs are normal neural structures located on the posterior border of the tongue that represent a non-neoplastic regional anatomic variation. In some cases, signs or symptoms may be present, and further investigation should be performed. Pathologists should be aware of this entity to avoid confusion with neural lesions.

Abstract
The effects of drugs of abuse on oral mucosa are only partly understood. The aims of the present study were to: (1) evaluate the frequency of nuclear changes in normal-appearing oral mucosa of alcoholics and crack cocaine users and (2) assess their association with cell proliferation rate. Oral smears were obtained from the border of the tongue and floor of the mouth of 26 crack cocaine users (24 males and 2 females), 29 alcoholics (17 males and 12 females), and 35 controls (17 males and 18 females). Histological slides were submitted to Feulgen staining to assess the frequency of micronuclei (MN), binucleated cells (BN), broken eggs (BE), and karyorrhexis (KR). A significant increase in the frequency of MN was observed in cells exfoliated from the tongue of crack cocaine users ( p = 0.01), and alcoholics showed a higher frequency of KR in cells obtained from the floor of the mouth ( p = 0.01). Our findings suggest that the use of crack cocaine induces clastogenic effects, whereas alcoholism is associated with higher degrees of keratinization in the floor of the mouth.

Abstract
Oral lichen planus (OLP) is a relatively common chronic mucocutaneous inflammatory disease and a search for novel therapeutic options has been performed. We sought to compare the efficacy of laser phototherapy (LPT) to topical clobetasol propionate 0.05% for the treatment of atrophic and erosive OLP. Forty-two patients with atrophic/erosive OLP were randomly allocated to two groups: clobetasol group (n=21): application of topical clobetasol propionate gel (0.05%) three times a day; LPT group (n=21): application of laser irradiation using InGaAlP diode laser three times a week. Evaluations were performed once a week during treatment (Days 7, 14, 21, and 30) and in four weeks (Day 60) and eight weeks (Day 90) after treatment. At the end of treatment (Day 30), significant reductions in all variables were found in both groups. The LPT group had a higher percentage of complete lesion resolution. At follow-up periods (Days 60 and 90), the LPT group maintained the clinical pattern seen at Day 30, with no recurrence of the lesions, whereas the clobetasol group exhibited worsening for all variables analyzed. These findings suggest that the LPT proved more effective than topical clobetasol 0.05% for the treatment of OLP.

Abstract
Oral Fibroma and Inflammatory Hyperplasia display similarities in their clinical and histopathological appearance. The present study proposed histopathological criteria for the differential diagnosis between those pathological entities. Histological sections of lesions histopathologically diagnosed as Oral Fibroma (n=61) and Inflammatory Hyperplasia (n=75) and were submitted to different techniques (Hematoxylin-Eosin; Masson Trichrome and Phosphomolybdic acid - Picrosirius red) to allow quantitative and qualitative analysis. The qualitative analysis of collagen density was based on sections stained by Hematoxylin-Eosin and focused in the center and periphery of each lesion. Wound and collagen fibers were more frequent and higher in Oral Fibroma, while parallel fibers were more frequent in Inflammatory Hyperplasia (Fisher’s exact test, p

Abstract
This investigation examined the effects of pharmacologically induced precocious puberty on cranial growth in Wistar rats. Forty-eight female newborn Wistar rats were divided into two groups: a control group (C) and an experimental group (E), with four subgroups of six animals each. The time interval from birth until sacrifice differed between the subgroups, and was set at 30, 60, 90, and 120 days. An intramuscular single dose (300 μg) of steroid hormone danazol was administered on day 5 after birth, as a means of inducing precocious puberty. Alizarin (2 mg/100 g) was administered to three animals in each subgroup three days prior to sacrifice. Body mass and dates corresponding to the beginning of the oestrous cycle were recorded. Craniometric measurements were undertaken. Histological analysis using light and fluorescence microscopy was then carried out to qualitatively and quantitatively evaluate the spheno-occipital synchondrosis and to visualize bone deposition patterns. The results were analysed with a Student's t-test and analysis of variance. Precocious puberty was effectively induced and differences between groups denoted an earlier maturation in the experimental rats. In qualitative analysis, a significant increase of total synchondrosis width was noted only in group E60, in comparison with C60, and an increase in the E90 subgroup cortical bone width compared with the C90 subgroup. Histomorphometrically, a statistical difference between total width values of subgroups E60 (434.3 μm) and C60 (323.5 μm) was detected. However, body mass and macroscopic measurements did not show statistically significant differences. An appropriate model for studying bone growth associated with precocious puberty in Wistar female rats was not achieved using steroid hormone danazol, when evaluated at 30 day intervals.

Abstract
The aim of this study was to evaluate the effects of acute alcohol consumption and vitamin E co-treatment upon oxidative stress parameters in rats tongue. Thirty-eight, Wistar rats were separated into five groups (alcohol, alcohol/vitamin E, control, Tween, vitamin E). Alcohol and alcohol vitamin E groups had the standard diet, and 40% alcohol on drinking water. Other groups were fed with the same standard diet and water ad libitum. Vitamin E was given by gavage to vitamin E and alcohol/vitamin E rats twice a week. Alcohol and control groups were subjected to saline gavage and Tween group to 5% Tween 80 solution, the vitamin E vehicle. At day 14, the animals were anesthetized and specimens were obtained from tongue. Lipid peroxidation (TBARS), protein oxidative damage, catalase (CAT) and superoxide dismutase (SOD) activities were quantified. Alcohol group decreased TBARS in relation to control group and alcohol vitamin-treated animals decreased TBARS when compared to Tween and vitamin E groups. SOD activity was lower and CAT activity was higher in animals treated with both alcohol and vitamin E. These results suggest that short-term alcohol consumption decreases lipid peroxidation levels. Alternatively, alcohol/vitamin E group increased CAT, showing the toxicity of this association.

Abstract
O consumo de álcool é um dos fatores de risco para o desenvolvimento do câncer bucal; entretanto, os mecanismos envolvidos no dano gerado pelo álcool são parcialmente compreendidos. Determinadas concentrações de álcool causam aumento da permeabilidade da mucosa bucal, potencializando a penetração de carcinógenos. Além disso, é responsável por um aumento na proliferação epitelial, bem como pela modificação do seu processo de maturação. Outras alterações, como redução da capacidade de reparo de DNA, distúrbios do sistema imune e do estado nutricional podem contribuir na sua relação com o desenvolvimento do câncer bucal. O metabolismo do álcool aumenta a produção de radicais livres e diminui os mecanismos antioxidantes, levando ao estresse oxidativo. O polimorfismo genético das enzimas de degradação do álcool pode ser responsável pela diferença na sensibilidade individual. Algumas isoformas dessas enzimas permitem o acúmulo de metabólitos tóxicos como o acetadeído, que pode causar dano ao DNA ou a outras estruturas celulares. A partir de uma revisão de literatura, esse trabalho tem como objetivo estabelecer uma relação entre os diferentes mecanismos da ação do álcool e a carcinogênese na cavidade oral.
