Three cases of generalized and severe HGF in young patients of the same family without other features are reported. The purpose of this article is to present documented cases and discuss the identification, treatment, and control of the disease. The histopathological characteristics of HGF are emphasized.

The aim of this study was to perform a literature review about the composition and functions of saliva as well as describe the factors that influence salivary flow (SF) and its biochemical composition. Background: Saliva represents an increasingly useful auxiliary means of diagnosis. Sialometry and sialochemistry are used to diagnose systemic illnesses, monitoring general health, and as an indicator of risk for diseases creating a close relation between oral and systemic health. Review: This review provides fundamental information about the salivary system in terms of normal values for SF and composition and a comprehensive review of the factors that affect this important system. Conclusion: Since several factors can influence salivary secretion and composition, a strictly standardized collection must be made so the above-mentioned exams are able to reflect the real functioning of the salivary glands and serve as efficient means for monitoring health. Clinical Significance: Since many oral and systemic conditions manifest themselves as changes in the flow and composition of saliva the dental practitioner is advised to remain up-to-date with the current literature on the subject.

ResumoIntrodução: A pesquisa das condições bucais de usuários de drogas é importante para ser conhecida esta população, cujo crescimento é ascendente no Brasil, a fim de que metas preventivas e atendimento adequado sejam traçados. Objetivo: Identificar o perfil sociodemográfico e a condição bucal desta população, em dois municípios paranaenses. Material e método: Foram coletados, por meio de questionário e de exame físico, dados de 100 indivíduos. Foram obtidos os seguintes valores: índice CPOD, profundidade de sondagem (PS), nível de inserção clínica (NIC), índice gengival (IG), índice de placa (IP) e sangramento à sondagem (SS). Após análise descritiva inicial, empregaram-se os testes t de Student e ANOVA one-way. Resultado: A média da idade foi 29,12 anos. As maiores frequências foram: gênero masculino (95,5%), solteiros (69,0%), baixa escolaridade (41%) e maior consumo de drogas lícitas -tabaco (90,9%) e álcool (84,5%) -, seguidas de crack (80,9%) e maconha (77,3%). A média do CPOD foi 15,21 (DP=5,84) e quanto maior o tempo de dependência, maior este índice (p<0,05). A média da PS foi 3,55 e do NIC, 3,59. O SS ocorreu em 82,7% dos casos e a inflamação moderada, em 79,5%. Placa detectável e moderado acúmulo de placa foram identificados em 39,5% e 35,3%, respectivamente. Conclusão: Predominaram indivíduos do gênero masculino, jovens, solteiros, com baixa escolaridade e consumidores de drogas lícitas e ilícitas, com condição bucal ruim. Sugere-se mais atenção dos profissionais da área odontológica e dos elaboradores de políticas públicas, com vistas a esta população.Descritores: Saúde bucal; usuários de drogas; epidemiologia. AbstractIntroduction: Epidemiological survey of the oral conditions of drug users is an important strategy to know this population, whose growth is increasing in Brazil, so that preventive goals and adequate treatment can be proposed. Aim: The aim of this study was to identify the sociodemographic profile and oral health condition of drug users in rehab of two municipalities of the State of Paraná. Material and method: One hundred individuals participated in the study, which data were collected by questionnaire and physical exam. The following values were obtained: DMFT index (decay-missing-filled index), probing depth (PD), clinical attachment level (CAL), gingival index (GI), plaque index (PI), and bleeding on probing (BOP). Data analyses were performed by Student t test and one-way ANOVA. Result: The mean age of participants was 29.12 years. The major frequencies were: male (95.5%), single (69.0%), lower schooling (41%) and higher consumption of licit drugs tobacco (90.9%) and alcohol (84.5%), followed by crack (80.9%), and marijuana (77.3%). The mean DMFT index was 15.21 (SD=5.84), and the longer the dependence time, the greater this index (p<0.05). Mean PD was 3.55 and mean CAL was 3.59. BOP occurred in 82.7% and 79.5% showed moderate inflammation. Detectable plaque and moderate plaque accumulation were observed in 39.5% and 35.3%, respectively. Conclusion: Prevalence was observed in ...

The aim of this longitudinal study was to assess the relation between the transverse craniofacial dimensions of subjects with Class II, Division 1 malocclusion and the breathing mode presented by them. Forty Angle Class II, Division 1 malocclusion subjects of both genders participated in the study, 23 of which were predominantly nose breathers and 17 were predominantly mouth breathers. The mean age ranged from 10 years and 9 months to 14 years -Age range 1; and from 13 years and 4 months to 16 years and 6 months -Age range 2. Measurements of six transverse craniofacial dimensions were performed in P-A teleradiographs: Total Sphenoid, Total Zygomatic, Total Nasal Cavity, Total Maxilla, Total Mastoid and Total Antegonion. The transversal craniofacial dimensions were measured and compared in both groups at age ranges 1 and 2. The longitudinal assessment of age ranges 1 and 2 showed that there was no statistically significant influence of the breathing mode on the craniofacial dimensions evaluated, or on the alteration of these dimensions. Breathing mode had no influence on craniofacial development in the sample studied.
