The aim of this study was to evaluate and to compare the effect of two fluoride varnishes and one fluoride/chlorhexidine varnish on Streptococcus mutans and Streptococcus sobrinus biofilm formation, in vitro. ⋯ The Fluor Protector + Cervitec varnish exerted prolonged antibacterial effects on S. mutans and S. sobrinus biofilms compared to the other varnishes tested.

Propolis and honey are natural bee products with wide range of biological and medicinal properties. The study investigated antimicrobial activity of ethyl alcohol extraction of propolis collected from Saudi Arabia (EEPS) and from Egypt (EEPE), and their synergistic effect when used with honey. Single and polymicrobial cultures of antibiotic resistant human pathogens were tested. ⋯ 1) propolis prevents the growth of the microorganisms in single and mixed microbial cultures, and has synergistic effect when used with honey or ethyl alcohol, 2) the antimicrobial property of propolis varies with geographical origin, and 3) this study will pave the way to isolate active ingredients from honey and propolis to be further tested individually or in combination against human resistant infections.

Maxillary bone losses often require additional regenerative procedures: as a supplement to the procedures of tissue regeneration, a platelet concentrate called PRF (Platelet Rich Fibrin) was tested for the first time in France by Dr. Choukroun. Aim of the present study is to investigate, clinically and histologically, the potential use of PRF, associated with deproteinized bovine bone (Bio-Oss), as grafting materials in pre-implantology sinus grafting of severe maxillary atrophy, in comparison with a control group, in which only deproteinized bovine bone (Bio-Oss) was used as reconstructive material. ⋯ The use of PRF and piezosurgery reduced the healing time, compared to the 150 days described in literature, favoring optimal bone regeneration. At 106 days, it is already possible to achieve good primary stability of endosseous implants, though lacking of functional loading.

To determine the role of laparoscopy in diagnosis and surgical treatment of perforated Meckel's diverticulum (MD) in adults. ⋯ To patients with sudden abdomen pain mimic acute appendicitis accompanied by a past medical history of bloody stools and/or chronic recurrent abdominal pain, proferated MD should be kept in mind as a differential diagnosis. Laparoscopy is a safe and effective surgical modality for diagnosis of proferated MD and has a therapeutic role that results in an excellent cosmetic result.

Comparative Study
What questions do people ask on a human papillomavirus website? A comparative analysis of public and private questions.
In 2004, we launched the question and answer (Q&A) section on a human papillomavirus (HPV) website (www.hpvkorea.org) that provides ample and regularly updated information about HPV. The purpose of this study is to collect data pertaining to questions posed on this website about HPV and its related diseases and analyze the type of questions and frequency before and after introduction of HPV vaccine in Korea. Using these results, we intend to determine the clinical and practical implications for doctors treating HPV and for HPV website providers. ⋯ Our results show that when people consult an internet site about HPV, they actually want to seek about "treatment of HPV and cervical dysplasia", "HPV transmission", "HPV remission", "genital warts", and "risk of cervical cancer" (in this order). Also, our results showed that "genital warts" and "HPV & pregnancy" may have been considered embarrassing topics. Thus, these findings can be used to make informed recommendations for future clinical or internet-based communications with patients and the general public.
