Effect of orthodontic force associated with cigarette smoke inhalation in healthy and diseased periodontium. A histometric and immunohistochemistry analysis in rats

Abstract

Within the limitations of the present study, it was concluded that cigarette smoke inhalation had no influence on the evaluated groups, even with the presence of low levels of nicotine, carbon monoxide and tar. The POTM groups did not present greater bone loss compared to P groups, thus periodontal disease is essential for bone loss.

Effect of two corticotomy protocols on periodontal tissue and orthodontic movement

“…experimental studies. 4,26,27,28 an commonly used method, 21,27,30,31,32 and micro-CT analyses evaluated bone microarchitecture and BMD.…”

“…The orthodontic devices were installed on the animals' lower first molar, as previously described. 21 After anesthesia, a 0.12 mm alloy wire (Morelli, Sorocaba, SP, Brazil) Surgical procedure G1 and G2 animals underwent surgery just after installation of the orthodontic appliance. G1 received trichotomy of the masseter muscle region, and the area was disinfected with chlorhexidine digluconate.…”

“…The muscle was repositioned and sutured with vicryl 4-0 and the skin was sutured with 3-0 silk. 21 The animals were euthanized through transcardial perfusion at 7 and 14 days. 24 Their hemi-mandibles were removed and stored in a buffered 4% paraformaldehyde solution for 72 hours.…”

“…The samples (n=6/group/antibody) were immunohistochemically processed as previously described. 21 We performed indirect immunoperoxidase…”

Benefícios da combinação dos tratamentos periodontal e ortodôntico em pacientes com comprometimento periodontal

“…ISSN 2525-8761 exemplo, após a intrusão de dentes extruídos em decorrência da PD, além de culminar em melhores condições na higiene oral por favorecer o rearranjo oclusal (REGO et al, 2010;CARVALHO et al, 2018;FERREIRA et al, 2018). Entretanto, sabe-se que, em grande parte dos casos, o TO de pacientes periodontalmente comprometidos é bastante restrito, devido ao suporte ósseo reduzido, ancoragem deficiente e ausência significativa de elementos dentários.…”
