INN may affect periodontal pathogenic bacteria, so we aimed to study the effect of INN on intraoral microbial profiles of periodontal disease and healthy periodontium. Our case-control study divided 180 subjects into six groups according to periodontal health status and INN usage as follows: healthy periodontium receiving INN (HINN; n = 30); those with generalized plaque-induced gingivitis receiving INN (GINN; n = 30); and those with stage I generalized periodontitis receiving INN (PINN; n = 30). Subjects not taking INN, were categorized in the same manner: those with a healthy periodontium (HC; n = 30); those with generalized plaque-induced gingivitis (GC; n = 30); and those with generalized periodontitis stage I (PC; n = 30). Plaque samples were collected to determine the prevalence of four periodontal pathogens (Porphyromonas gingivalis, Tannerella forsythia, Treponema dentic...

Material and methods: A case-control study was conducted with a total of 180 human adults divided into six groups. Clinical parameters, including pocket depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were measured at six sites per tooth. Whole unstimulated saliva samples were collected from all subjects to detect salivary level of MMP-8, MMP-9 using Enzyme-linked immunosorbent assay (ELISA). Data were analyzed using IBM SPSS Software. Kruskal Wallis test and Mann-Whitney U-tests were used to test any significant differences in any of the groups on all parameters. Pearson Chi-square test was used to compare the distribution of categorical responses across the study group...

Studies that compared pre- and postextraction radiographs suggest that maxillary sinus pneumatization may occur after posterior tooth extractions. This study’s aim was to establish the prevalence of maxillary sinus pneumatization following extractions in Riyadh, Saudi Arabia. Material and methodology In this cross-sectional study, 282 panoramic images were randomly selected from the radiology department of the Dental University Hospital in Riyadh, Saudi Arabia, from the years 2015 to 2018. The radiographs included were of patients who had one of the following teeth extracted: the second premolar, the first molar, or the second molar. These radiographs were then evaluated for sinus pneumatization following extractions. The distance between the sinus floor and the inferior border of the ...

To assess the variation in TIMP-1 and TIMP-2 observed at different stages of periodontal disease in comparison to those observed in the case of healthy periodontium. Materials and methods An examiner-blind case-control study involving 180 human adults divided into six groups based on their periodontal status. Clinical parameters, including pocket depth, clinical attachment level, and bleeding on probing were measured at six sites per tooth. Whole unstimulated saliva samples were collected from all subjects to evaluate salivary flow rate (SFR). Salivary TIMP-1 and TIMP-2 levels were detected using enzyme-linked immunosorbent assay (ELISA). Data were analyzed using IBM SPSS Software. The Kruskal Wallis test and Mann-Whitney U-tests were employed to verify any significant differences between the groups for all ...
