Background Ridge resorption following tooth extraction may be reduced by alveolar ridge preservation (ARP). Previous randomized clinical trials and systematic reviews have suggested that autogenous tooth bone graft (ATB) can be an effective alternative material for ARP. However, the results are heterogeneous. Therefore, our research aimed to evaluate the efficacy of ATB in ARP. Methods A systematic search was conducted in Cochrane Library, Embase, MEDLINE and Scopus for studies published from inception to 31 November 2021. We searched searched for randomized, non-randomized controlled trials and case series reporting on ATB use for ARP. The primary outcome was the ridge width difference pre- and post-surgery, measured in millimetres (mm) measured on CBCT (cone beam computed tomography). The secondary outcomes were the histological results. We followed the PRISMA2020 recommendations for reporting our systematic review and meta-analysis. Results The analysis included eight studies for the primary and six for the secondary outcomes. The meta-analysis revealed a positive ridge preservation effect with a pooled mean difference ridge width change of -0.72 mm. The pooled mean residual graft proportion was 11.61%, and the newly formed bone proportion was 40.23%. The pooled mean of newly formed bone proportion was higher in the group where ATB originated from both the root and crown of the tooth. Conclusions ATB is an effective particulate graft material in ARP. Complete demineralization of the ATB tends to decrease the proportion of newly formed bone. ATB can be an attractive option for ARP. Trial registration The study protocol was registered on PROSPERO (CRD42021287890).

Összefoglaló. Bevezetés: A kiégés jelensége fokozottan érinti az egészségügyi dolgozókat, a nagyfokú stressz, a folyamatos fizikai és emocionális megterhelés miatt. A kiégés mérését fogorvosok körében végeztük, mivel Magyarországon még nem készült csak fogorvosokat mérő keresztmetszeti vizsgálat. Célkitűzés: Elsődleges célunk a fogorvosi kiégés előfordulásának, súlyosságának mérése, a rizikófaktorok kiszűrése volt. Másodlagos célul a kiégés veszélyére való figyelem felkeltését tűztük ki az érintett csoportban. Módszer: Az adatgyűjtés a ’Maslach Burnout Inventory – Human Services Survey’ 22 tételes magyar, validált változatával történt online formában. Eredmények: Online kérdőívünket 407 fogorvos töltötte ki. A következő eredményeket kaptuk: az emocionális kimerülés esetében a válaszadók 20%-a (81 fő) tartozik a magas kategóriába, a cinizmus dimenziójának esetében a válaszadók 17,5%-át (70 fő) jellemzi a magas pontszám. A teljesítményvesztés magas dimenziója a minta 75%-ában (302 fő) volt igazolható. Szignifikáns (p≤0,05) védőfaktornak találtuk a harmonikus kollegiális viszonyt, a hobbi meglétét, a 2–4 óra napi munkát, a támogató otthoni és munkahelyi légkört, az egészségi probléma és a saját vállalkozás hiányát. Szignifikáns negatív eltérést 6–10 éve dolgozó férfiak körében találtunk. Következtetés: Az eredmények felhívják a figyelmet a legfontosabb protektív tényezőkre, melyek segítségével csökkenthető a kiégés mértéke. Orv Hetil. 2021; 162(11): 419–424. Summary. Introduction: Burnout has an increased impact on healthcare workers due to severe stress, constant physical and emotional strain. Burnout was measured among dentists, as no such cross-sectional study has been made in Hungary. Objective: Our primary goal was to measure the incidence and severity of dental burnout and to screen for the risk factors. Our secondary goal was to raise awareness of the risk of burnout in the affected group. Method: Data collection was performed online with the 22-item Hungarian validated version of Maslach Burnout Inventory – Human Services Survey. Results: 407 dentists completed our online questionnaire. The following results were obtained: in the case of emotional exhaustion, 20% of the respondents belong to the high category, in the cynicism dimension, 17.5% of the respondents have high scores. The high dimension of performance loss is typical in 75% of the sample. We found that harmonious collegial relationships, the existence of a hobby, 2–4 hours of daily work, a supportive home and work atmosphere, the lack of health problems and self-employment are significant (p≤0.05) protective factors. Significant negative differences were found among men who had been working for 6–10 years. Conclusion: The results draw attention to the most important protective factors that can help reduce the rate of burnout. Orv Hetil. 2021; 162(11): 419–424.

Objectives We aimed to conduct a systematic review on published data in order to investigate the efficacy of mouthwash products containing chlorine dioxide in halitosis. Study design Systematic review and meta-analysis Methods Our search was conducted on 14th October 2021. We searched the following electronic databases: MEDLINE, Embase, Scopus, Web of Science, and CENTRAL. We analysed data on adults with halitosis, included only randomised controlled trials and excluded in vitro and animal studies. The interventional groups used chlorine dioxide, and the comparator groups used a placebo or other mouthwash. Our primary outcomes were changes in organoleptic test scores (OLS) and Volatile Sulfur Compound (VSC) levels from baseline to the last available follow-up. Results We found 325 articles in databases. After the selection process, ten articles were eligible for qualitative synthesis, and 7 RCTs with 234 patients were involved in the meta-analysis. Our findings showed a significant improvement in the parameters of the chlorine dioxide group compared to the placebo group in OLS one-day data (mean difference (MD): -0.82; 95% confidence intervals (95% CIs): [-1.04 –-0.6]; heterogeneity: I2 = 0%, p = 0.67); and one-week OLS data (MD: -0.24; 95% CIs: [-0.41 –-0.07]; I2 = 0%, p = 0.52); and also changes in H2S one-day data (standardised mean difference (SMD): -1.81; 95% CIs: [-2.52 –-1.10]); I2 = 73.4%, p = 0.02). Conclusion Our data indicate that chlorine dioxide mouthwash may be a good supportive therapy in oral halitosis without known side effects.
