BACKGROUND The aim of this study was to compare the recovery of three putative periodontal pathogens from periodontal lesions in samples using paper points inserted to different depths of the lesions. METHODS Twenty 6-8 mm deep periodontal lesions with bleeding on probing were studied. Microbial samples were obtained using paper points inserted to three different depths of the lesions: orific...

Dental and dental hygiene students must acquire the skill of measuring periodontal pockets and learn to identify the bottom of a pocket, especially of deep periodontal pockets. A new dental model that would enable students to practice measuring deep periodontal pockets was developed at the Tokyo Medical and Dental University. The purpose of this study was to evaluate the feasibility and effecti...

Objective. The aim of this study was to assess the influence of implant-abutment interface (IAI) placement depths on peri-implant tissues in the presence of ligature-induced peri-implant inflammation. Materials and Methods. Two implants with screwed-in IAIs (SI) and two implants with tapped-in IAIs (TI) were inserted in one side of the mandible in six dogs eight weeks after tooth extraction. Fo...

The purpose of this study was to locate the common discrepancy sites in a periodontal examination by new student dentists in a dental school setting and to evaluate student progress after one year of clinical training. Sixty-nine patients were enrolled in the initial phase of this study. Periodontal probing examinations were performed by both dental students and calibrated faculty members. A to...

A new ultrasonic periodontal probe has been developed that offers the potential for earlier detection of periodontal disease activity, non-invasive diagnosis, and greater reliability of measurement. A comparison study of the ultrasonic probe to both a manual probe, and a controlled-force probe was conducted to evaluate its clinical effectiveness. Twelve patients enrolled into this study. Two ha...

Aim: the aim of present study was Evaluate clinical outcome residual subgingival cement in Prosthetic Dentures Reliant on Dental Implants. Method: Databases PubMed, Scopus, Web Science, EBSCO and Embase were searched for systematic literature until March 2022. 95% confidence interval effect size with fixed model Inverse-variance method calculated. Meta-analysis performed using Stata/MP v.16 sof...

objective: low quality of the bone and insufficient bone due to the size of the sinus and resorption of the alveolar ridge decrease the long-term survival of implants in the posterior maxilla compared to other regions of the jaws. surgical procedures to increase bone volume make it possible to place implants longer than 8 mm. in this situation sinus elevation makes it possible to place implants...

This study was conducted to compare the success of implants restored with angled abutments to implants restored with standard abutments. Eighty-one implants in 24 patients were evaluated for up to 36 months. Measurements included probing depths, gingival level, gingival index, and mobility. No significant difference could be found for any of the parameters examined between implants restored wit...

purpose: to determine long-term outcomes of probing in adult patients with nasolacrimal duct (nld) obstruction. methods: patients older than 20 years admitted in labaffinejad hospital with complete nasolacrimal duct obstruction were studied. the selected patients underwent probing under local anesthesia and cases with successful nld probing enrolled the study. patients were examined during the ...
