Isotretinoin effect on alveolar repair after exodontia-a study in rats.
Summary of "Isotretinoin effect on alveolar repair after exodontia-a study in rats."
To evaluate isotretinoin effect on alveolar repair after tooth extraction of maxillary incisor and serum calcium levels in rats. STUDY
Wistar rats (60-day-old) were assigned to control (CG, n = 12) and experimental (EG, n = 20) groups. EG received daily isotretinoin (7.5 mg/kg) for 30 days before surgery and until euthanasia, 7, 21, 28, or 90 days after tooth extraction. Blood was collected in the EG to analyze serum calcium levels before isotretinoin administration and at euthanasia. Right hemimaxillae underwent histological examination, and the slides were stained with HE and analyzed by descriptive light microscopy.
There was acceleration in the process of alveolar repair in the EG at all time points when compared to controls. Serum calcium levels showed a statistically significant decrease between first and second blood collection at days 21, 28, and 90.
Daily isotretinoin in a dose corresponding to the treatment of cystic acne accelerated alveolar repair.

Isotretinoin is the standard treatment for refractory severe nodulocystic acne. A true association between prior isotretinoin use and development of inflammatory bowel disease (IBD) is uncertain. Addr...
This study has attempted to evaluate the effects of ellagic acid (EA) on alveolar bone healing after tooth extraction in rats.
Acne is a self limiting condition that often results in scarring and disfigurement disproportionate to its clinical severity. Isotretinoin is considered the gold standard in the medical management of ...
Objectives : Can a synthetic bone substitute be used to repair the alveolar cleft to bypass donor site morbidity as well as to shorten the operating time? In earlier experimental studies, micro-str...
The purpose of this research is to determine if a subject's own bone marrow tissue can help regenerate bone in the area of his/her jaw where a tooth has been removed using Tissue Repair Ce...
The purpose of this study is to compare the efficacy and safety of CIP-Isotretinoin and a marketed (generic) formulation of isotretinoin when both are administered twice daily with meals.

The purpose of this study is to document and evaluate how protective covering materials (a barrier membrane called OSSIX-Plus) can help preserve bone size after a tooth is removed. As you ...

Medical and Biotech [MESH] Definitions
Inbred rats derived from Sprague-Dawley rats and used for the study of salt-dependent hypertension. Salt-sensitive and salt-resistant strains have been selectively bred to show the opposite genetically determined blood pressure responses to excess sodium chloride ingestion.
Factors that modify the effect of the putative causal factor(s) under study.
An outbred strain of rats developed in 1915 by crossing several Wistar Institute white females with a wild gray male. Inbred strains have been derived from this original outbred strain, including Long-Evans cinnamon rats (RATS, INBRED LEC) and Otsuka-Long-Evans-Tokushima Fatty rats (RATS, INBRED OLETF), which are models for Wilson's disease and non-insulin dependent diabetes mellitus, respectively.
The reconstruction of a continuous two-stranded DNA molecule without mismatch from a molecule which contained damaged regions. The major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. Excision repair and post-replication repair are sometimes referred to as "dark repair" because they do not require light.
Mutant strains of rats that produce little or no hair. Several different homozygous recessive mutations can cause hairlessness in rats including rnu/rnu (Rowett nude), fz/fz (fuzzy), shn/shn (shorn), and nznu/nznu (New Zealand nude). Note that while NUDE RATS are often hairless, they are most characteristically athymic.
