Is periodontal disease a risk factor for developing severe Covid-19 infection? The potential role of Galectin-3.

Impact Statement: There could be a close relationship between periodontal diseases (PDs) severity and Covid-19 infections. This relationship could be caused by Galectin-3-mediated increased immune response and increased viral attachment. Keeping PDs under control and maintaining rigorous oral hygiene during this troubled Covid-19 pandemic period is very important.

Aggressive periodontitis with streptococcal gingivitis: a case report.

Acute streptococcal gingivitis is an acute inflammation of the oral mucosa and also may be seen with the other oral diseases as aggressive periodontitis that is characterized by a considerable attachment loss over a relatively short period of time. Streptococcal infections of gingiva are seen rarely; also the origin of this gingival inflammation is occasionally different from that of routine plaque-associated gingivitis. The clinical features and treatment methods of these diseases are already reported in previous literatures.

The study based on periodontal condition, blood group, and medical history.

Differences in dental and bone maturation in regions with or without hemihypertrophy in two patients with Russell-Silver syndrome.

Hemihypertrophy (hemihyperplasia) is defined as asymmetric body overgrowth of one or more body parts. Hemihypertrophy can be isolated or be part of well-defined syndromes, such as Russell-Silver syndrome (RSS). RSS is characterized by severe intrauterine growth retardation, postnatal short stature, asymmetry of the face, body, and limbs, short and incurved fifth fingers, broad forehead, pointed small triangular shaped face, girdle nose, normal psychomotor development, variations in the pattern of sexual development, and dental and oral abnormalities.

The gingival crevicular fluid ciprofloxacin level in subjects with gingivitis and periodontitis, and its effects on clinical parameters.

Objectives: The purpose of this study, conducted on patients with gingivitis and periodontitis, was twofold: to find out the serum and gingival crevicular fluid concentration of ciprofloxacin, which is a common drug used effectively against Actinobacillus actinomycetemcomitans and to determine the effects of ciprofloxacin administration on clinical parameters.

Method: A total of 32 adult patients, consisting of 16 subjects with gingivitis and 16 subjects with untreated chronic periodontitis, were included in the study. The subjects were divided into four groups: group I included eight subjects with chronic gingivitis who had not previously received any ciprofloxacin; group II included eight subjects with chronic gingivitis to whom three doses of ciprofloxacin were administered (Siprosan 500 mg) to establish adequate gingival crevicular fluid and serum concentrations of the agent; group III consisted of eight subjects with chronic periodontitis who had not received any ciprofloxacin; group IV included eight subjects with chronic periodontitis to whom three doses of ciprofloxacin were administered to establish adequate gingival crevicular fluid and serum concentrations of the agent.
