Halitosis is a growing issue and its management is highly challenging. The aim of this study was to evaluate the knowledge and treatment strategies used by French (FD) and Lebanese (LD) dentists. A self-administered structured questionnaire was sent to FD and LD comprising questions about professional characteristics, management, and treatment of halitosis, patients’ referral, and halitosis-related knowledge. A multivariate analysis was conducted to determine differences between FD and LD and to identify parameters that could influence dentists’ management of halitosis. The questionnaire was filled out by 156 FD and 257 LD. Among them, 78.8% of FD and 68.9% of LD were confronted with halitosis management, while only a few routinely asked their patients about halitosis (16% FD, 13.2% LD). Regarding anamnesis, oral hygiene habits were more investigated by FD than LD (p < 0.05). The overall treatment satisfaction was low with 39.7% of FD and 28.4% of LD considering their treatment effective. Regarding halitosis-related knowledge, extra-oral causes were overestimated in both populations. FD (83.4%) and LD (65.8%) considered their education regarding halitosis as insufficient. This study highlights the need of professional education in both countries, targeting proper diagnosis and treatment strategies of halitosis.

Aim. Several limiting factors encourage the clinician to use short implants. Among those, the presence of limiting anatomical elements and the simplification of surgical procedures are particularly significant. The goal of this study is to analyse the opportunity to extend the use of short implants to extrashort implants with a length less than 5mm (ESI). Materials and Methods. Seven patients (3 women, 4 men; mean age 60.4 years) received extrashort implants (Straumann Implant, Palatal Orthosystem, length 4.2mm, diameter 4.1 or 4.8mm) in severe resorbed edentulous posterior areas. The implants were incorporated in partially fixed dentures. The osseous stability and the attachment level were recorded after a loading period of 22 to 54 months. Results. The results demonstrated a success rate of 100%, stability in the osseous level surrounding implants (mean annual mesial and distal loss of 0.026mm and 0.105mm, resp.), and no significant differences in the mean attachment depth between extrashort implants and contralateral teeth or implants (3.7mm versus 3.55mm, SD = 0.87). Splinting ESI with natural teeth resulted in significantly more bone resorption than with other implants (). Conclusion. This exploratory study on the use of extrashort implants demonstrated good reliability over a loading period of 22 to 54 months. Aim.
