Abstract Purpose The aim of this study was to compare the clinical outcomes of diode laser excision with conventional scalpel surgery in the management of gingival pyogenic granuloma.

Type II diabetes mellitus (T2DM) is characterized by chronic low-grade inflammation and impaired wound healing, which may have undesirable effects on the outcomes of oral surgery. The expression of proinflammatory cytokines, including IL-6 and IL-8, is fundamental in immune regulation and for tissue damage or recovery. The purpose of the present investigation was to measure salivary IL-6 and IL-8 in patients with type II diabetes mellitus before and after undergoing tooth extraction, as well as in a control group of systemically healthy individuals. This was an observational case–control study that was performed at the college of dentistry university of Kufa, Al Najaf, Iraq from April 2025 to December 2025. Sixty individuals participated in the study, including 30 T2DM patients and 30 gender- and age-matched healthy controls. Unstimulated whole saliva was collected one hour before extraction and two days after extraction. Enzyme linked immunosorbent assay (ELISA) was used to determine the levels of IL-6 and IL-8 in saliva. The statistical analysis between the two groups was analyzed by independent-samples and paired t-test with P < 0.05 considered as significant. At baseline, the concentrations of salivary IL-6 and IL-8 was significantly higher in patients with T2DM compared to controls (P < 0.05). Both cytokines were significantly elevated (P < 0.001) when compared with the basal values in diabetics on day 2 following tooth extraction; this difference was still statistically significant from that observed in controls (P < 0.05). Type II diabetes mellitus patients have a high salivary level of IL 6 and IL-8 at the baseline and an exaggerated response to inflammation after tooth extraction. These results indicate that diabetic patients have a chronic inflammatory phase, which might affect the ability to heal wounds. Salivary IL-6 and IL-8 can be potentially useful, non-invasive biomarkers for monitoring POI in T2DM patients.

Background: Resorption of Crestal bone after implant placement is considered one of the most importantnparameters for implant success. Immediate implant placed in the extraction socket for reducing treatment time. Aim: this study was aiming to make comparison between the immediate and delayed placement of dental implant in the Crestal bone width in bucco- lingual direction clinically and radiographically by using the cone beam computed tomography.

ABSTRACT This research aimed to determine the relationship between the maxillary posterior teeth and maxillary sinus floor (MSF), as well as the impact of nearby tooth loss on the space between MSF and posterior maxillary roots. A number of 120 digital panoramic radiographs were obtained from the archives of several clinics in Al-Najaf, Iraq, with the overall teeth examined in these radiographs including 236 of the 1st premolars, 227 of the 2nd premolars, 227 of the 1st molars, and 231 of the 2nd molars, from the right and left sides. The distances between the apices of the teeth and the maxillary sinus were determined. There are three categories of relationships between upper posterior teeth roots and MSF. These include type Os (root apex exists below or outside MSF), Type Co (root apex in contact with the MSF), and Type Is (root apex above or inside MSF). Type Os is the most encountered among premolars, Type Co is mostly encountered among the 2nd molars, and Type Is, in the 1st and 2nd molars. The study finds no correlation between age, gender, and the distribution of maxillary posterior tooth roots attached to the MSF. The first premolars were the furthest from MS, while the first molars were the closest. The most frequent link between maxillary molar roots and the MS was the Co-relation for the 2nd maxillary molar and the Is relation for the 1st maxillary molar. There is a non-significant decrease in the distance between the apices of the 1st maxillary premolar, 2nd maxillary premolar, and 1st maxillary molar and the MS before and after extraction. KEYWORDS: panoramic radiography, floor of maxillary sinus, upper posterior teeth ABBREVIATIONS: MSF: Maxillary Sinus Floor; MS: Maxillary Sinus; Co: Root in contact with sinus floor; Is: Root inside the sinus; Os: Root outside the sinus

This study aim to evaluate and compare the deflection of premolar teeth cusps that filled incrementally with conventional composite (Universal Ceram X One Sphere TEC TM) and various types of bulk fill composite materials (Kerr SonicFillTM3 , 3M FiltekTM Bulk Fill and Shofu Beautifil Bulk Fill). In this study 40 human, healthy maxillary first premolars were collected and large MOD cavity were prepared in them . According to restorative materials, the teeth were haphazardly categorized in 4 groups (n=10 per group). Group I : The teeth were filled with SonicFill™3 Kerr composite, Group II : The teeth were filled with Filtek Bulk Fill, Group III : The teeth filled with Shofu Beautifil Bulk Fill composite, and Group IV : The Teeth were filled with Dentsply Ceram X One Sphere TEC TM. By the aid of digital microscope intercuspal distance on the tips of the cusps between two index reference points was measured pre preparation of the cavity , post preparation, after 15 minutes of completion of fillings. The cuspal deflection was calculated by determination of the changes in measurements. Inward cuspal deflection was occurred in all teeth after filling , minimal cuspal deflection reported in all study groups that filled with bulk fill filling in comparison with group IV that filled in layering technique with conventional composite. Greater cuspal deflection produced by Beautifil Bulk Fill restorative in comparison with other groups. As a conclusion of this study that using of new bulk filling restorative materials could dramatically minimize cuspal deflection.
