Influence of rheumatoid arthritis on peri-implant diseases: A longitudinal retrospective clinical and radiographic evaluation.

Background: To investigate the effect of rheumatoid arthritis (RA) on the incidence of peri-implantitis (PI) and peri-implant mucositis (PIM).

Methods: Radiographic and clinical chart reviews were conducted to measure the probing depth (PD), bleeding on probing, and marginal bone loss (MBL) around the implants to diagnose peri-implant diseases based on the 2017 workshop classification. Values were recorded at the baseline (T0) to the last available chart and radiograph (T1).

Narghile (water pipe) smoking among university students in Jordan: prevalence, pattern and beliefs.

Background And Objectives: Narghile is becoming the favorite form of tobacco use by youth globally. This problem has received more attention in recent years. The aim of this study was to investigate the prevalence and pattern of narghile use among students in three public Jordanian universities; to assess their beliefs about narghile's adverse health consequences; and to evaluate their awareness of oral health and oral hygiene.

Predicting recurrent aphthous ulceration using genetic algorithms-optimized neural networks.

Objective: To construct and optimize a neural network that is capable of predicting the occurrence of recurrent aphthous ulceration (RAU) based on a set of appropriate input data.

Participants And Methods: Artificial neural networks (ANN) software employing genetic algorithms to optimize the architecture neural networks was used. Input and output data of 86 participants (predisposing factors and status of the participants with regards to recurrent aphthous ulceration) were used to construct and train the neural networks.
