HS in periodontal immuneinflammatory response and bone loss: a study in rats.

Acta Odontol Latinoam 2019 Dec;32(3):164-171

Faculdade São Leopoldo Mandic, Departamento de Periodontia, Campinas, Sao Paulo - Brasil.

Halitosis is highly prevalent in periodontitis and attributed mainly to the presence of volatile sulfur compounds (VSC), where hydrogen sulfide (H2S) is the chief culprit in the characteristic malodor of periodontitis and thus may play an active role in its pathogenesis. The aim of this study was to evaluate the effect of H2S in the acute, intermediate and chronic immuneinflammatory host response and alveolar bone loss in vivo by using an animal model of induced periodontal disease. Thirtysix rats were divided into 2 groups: test group (n = 18), rats exposed to H2S (NaHS H2S donor molecule) and control group (n = 18), rats treated with saline only (Ctrl). Read More

Acta Odontol Latinoam 2019 Apr;32(1):10-16

Universidad de Buenos Aires, Facultad de Odontologia, Cátedra de Periodoncia , Buenos Aires, Argentina.

Subepithelial connective tissue graft (SCTG) is an essential therapeutic tool in periodontal plastic surgery and implantology. The aim of this preliminary study was to observe and make a histological and histomorphometric comparison of the composition of subepithelial connective tissue grafts (SCTGs) harvested from the palatal mucosa by two different harvesting techniques: mucoperiosteal (lamina propria and complete submucosa including periosteum) and mucosal (lamina propria and a portion of the submucosa). The main hypothesis proposes that SCTG harvested with the mucosal technique contains a greater proportion of connective tissue proper (CTP) and a lower proportion of adipose tissue (AT) than the mucoperiosteal technique.

The aim of this study was to assess whether caries risk, nutritional status, access to dental care and socio-behavioral factors are associated to two caries experience outcome variables using the Epidemiologic International Caries Detection and Assessment System (ICDASepi), which includes initial enamel caries lesions: 1- The presence of ICDAS-epi caries experience (dmf-ICDASepi ≥ 1), and 2- Having an ICDAS-epi caries experience (dmft-ICDASepi) higher than national figures for the same age. The sample included 316 eight- to 71-month-old children from the municipality of Anapoima, Colombia. Assessments included: prevalence and mean of caries experience using the ICDASepi system without compressed air-drying of teeth surfaces (dmf-ICDASepi), caries risk and nutritional status. Read More

Factors associated to apical overfilling after a thermoplastic obturation technique - Calamus® or Guttacore®: a randomized clinical experiment.

Acta Odontol Latinoam 2018 Jun;31(1):45-52

Universidad el Bosque, Facultad de Odontología, Posgrado de Endodoncia Bogotá, Colombia.

The aims of this study were to analyze whether age, tooth type and sex are related to radiographically visible extrusion of filling material as an unintended outcome in teeth undergoing endodontic treatment with a thermoplastic obturation technique (Calamus® or GuttaCore®) and to determine whether the presence of such overfilling is associated to postoperative pain. We selected 120 teeth with diagnoses involving vital pulp and indication for endodontic treatment. Biomechanical preparation was performed using the Protaper Next® system with X2 or X3 master apical file. Read More

Universidad Del Salvador, Facultad de Ciencias Médicas, Escuela de Odontologia, Cátedra de Fisiología General y Neurofisiologia. Buenos Aires, Argentina.

Major gingival-periodontal changes according to age have been observed in both diabetic and non-diabetic rats. Male Wistar rats weighing 200-220 g were divided into two groups: 1) Nondiabetic (ND) and 2) Diabetic (D) by receiving an intraperitoneal (ip) dose of streptozotocin (STZ) (50 mg /kg). Animals from both groups (ND and D) were euthanized at 4, 8, 12, 17 y 25 weeks after treatment with saline solution or STZ. Read More
