Halitoza
Epidemiologia

Halitoza, definiowana jako nieprzyjemny zapach z ust (fetor ex ore), dotyka około 31,8% populacji globalnie (95% CI: 24,6-39,0%), z wyższym rozpowszechnieniem w krajach o niskim i średnim dochodzie (39,8%, 95% CI: 21,1-54,9%) w porównaniu do krajów rozwiniętych (29,0%, 95% CI: 21,2-36,8%). Epidemiologia halitozy jest zróżnicowana geograficznie i demograficznie, z odsetkiem sięgającym 50% w USA oraz wahaniami od 6% do 65,9% w populacjach azjatyckich. Czynniki ryzyka obejmują nalot na języku, choroby przyzębia, próchnicę (z ryzykiem zwiększonym 8,74-krotnie), nieodpowiednią higienę jamy ustnej oraz kserostomię. Pozaustne przyczyny, takie jak palenie tytoniu (2,69-krotnie wyższe ryzyko), choroby układu oddechowego, pokarmowego i metabolicznego, stanowią mniejszy odsetek przypadków. Halitoza znacząco wpływa na jakość życia, zwiększając ryzyko stresu o 60% i depresji u 57% pacjentów, a także prowadząc do społecznego wykluczenia i rozważań nad inwazyjnymi zabiegami chirurgicznymi, które są skuteczne w mniej niż 3% przypadków.

Epidemiologia halitozy

Halitoza (nieprzyjemny zapach z ust, fetor ex ore) jest powszechnym problemem zdrowotnym dotykającym znaczną część populacji na całym świecie. Termin ten powstał z połączenia łacińskiego słowa „halitus” (oddech) oraz greckiego „osis” (proces patologiczny) i odnosi się do nieprzyjemnego zapachu wydobywającego się z jamy ustnej12. Dokładne oszacowanie rozpowszechnienia halitozy jest trudne ze względu na brak jednoznacznych kryteriów definiujących „zły oddech” oraz jego nasilenie, co skutkuje brakiem standaryzacji społecznej i etnicznej w ocenie nieprzyjemnego zapachu13.

Globalne rozpowszechnienie halitozy

Według najnowszych badań, ogólnoświatowe rozpowszechnienie halitozy szacuje się na około 31,8% populacji (95% CI: 24,6-39,0%)45. Wartości te różnią się w zależności od regionu geograficznego i metodologii badania. W krajach rozwiniętych szacunkowe rozpowszechnienie wynosi około 29,0% (95% CI: 21,2-36,8%), podczas gdy w krajach o niskim i średnim dochodzie sięga 39,8% (95% CI: 21,1-54,9%)4.

Różnice w danych epidemiologicznych są znaczące, co widać w poszczególnych badaniach6:

  • W Stanach Zjednoczonych szacuje się, że około 50% populacji dorosłych doświadcza halitozy w pewnym momencie życia67
  • W Chinach rozpowszechnienie halitozy wynosi od 6% do 23%68
  • Wśród indyjskich studentów stomatologii halitoza występuje u 21,7% mężczyzn i 35,3% kobiet6
  • Według innych badań, około 65,9% osób w populacji chińskiej cierpi na halitozę, z wyższym odsetkiem u mężczyzn (55,6%) niż u kobiet (44,4%)9
  • W Bangladeszu, badanie wśród studentów uniwersytetów wykazało, że 55,97% respondentów zgłasza samocenioną halitozę10

Niektóre badania wskazują również, że ciężkie przypadki halitozy stanowią około 5% całkowitej populacji1112. Według Cleveland Clinic, halitoza dotyka około 1 na 4 osoby na świecie, a kombinowane wyniki 13 artykułów z czasopism medycznych wykazały, że dotyczy ona około 31,8% populacji13.

Czynniki demograficzne i społeczne

Wiek i płeć mogą mieć wpływ na występowanie halitozy, choć dane w tym zakresie nie są jednoznaczne5. Niektóre badania sugerują, że częstość występowania halitozy wzrasta z wiekiem6. Związane jest to między innymi ze zmniejszoną produkcją śliny u osób starszych oraz zwiększonym prawdopodobieństwem stosowania leków mogących powodować suchość w jamie ustnej14.

Jeśli chodzi o różnice między płciami, dane są niejednoznaczne. Badania w Chinach wykazały wyższy odsetek halitozy u mężczyzn (55,6%) niż u kobiet (44,4%)9, podczas gdy w Bangladeszu wykazano, że kobiety (74,53%) zgłaszały znacznie wyższy odsetek samocenionej halitozy niż mężczyźni (36,94%)10.

Czynniki socjoekonomiczne również mogą wpływać na występowanie halitozy. Badania wykazały statystycznie istotny związek między zamieszkiwaniem na obszarach wiejskich, niskim miesięcznym dochodem a występowaniem halitozy jamy ustnej15.

Znaczenie kliniczne halitozy

Halitoza stanowi trzeci najczęstszy powód wizyt u dentysty, po próchnicy zębów i chorobach przyzębia615. Według jednego z badań, halitoza znajduje się wśród 100 najbardziej stresujących dolegliwości u ludzi6, co podkreśla jej znaczący wpływ na jakość życia pacjentów.

Świadomość problemu i jego wpływ na jakość życia

Ważnym aspektem epidemiologii halitozy jest świadomość problemu wśród osób dotkniętych tym schorzeniem. Wiele osób cierpiących na halitozę nie jest świadomych swojego problemu i dowiaduje się o nim od innych osób25. Badanie przeprowadzone wśród 160 osób z halitozą wykazało, że tylko 42 osoby (20,5%) były świadome swojego problemu, podczas gdy 118 osób (57,6%) nie zdawało sobie z niego sprawy16.

Halitoza może mieć znaczący wpływ na jakość życia i funkcjonowanie społeczne5. Badania wykazują, że:

  • Osoby z nieprzyjemnym zapachem z ust są o 60% bardziej narażone na stres niż osoby bez tego problemu17
  • 57% osób cierpiących na halitozę zgłasza uczucie depresji związane z tym problemem17
  • 71% osób z halitozą rozważało poddanie się bolesnym i inwazyjnym zabiegom chirurgicznym w celu eliminacji problemu, mimo że operacje są skuteczne w mniej niż 3% przypadków17

Halitoza powoduje znaczne ograniczenia społeczne i może prowadzić do zawstydzenia u większości pacjentów, wpływając na ich codzienne życie1812.

Nadzór i monitoring halitozy

Monitorowanie halitozy w populacji jest utrudnione ze względu na kilka czynników3:

  • Halitoza podlega społecznemu tabu i stygmatyzacji, co może wpływać na chęć udziału w badaniach lub rzetelnego raportowania doświadczeń związanych z tym schorzeniem
  • Brak uniwersalnej zgody co do kryteriów diagnostycznych i metod wykrywania, które powinny być stosowane do określenia, które osoby mają halitozę, a które nie
  • Niektóre badania opierają się na samoocenie halitozy, a istnieją wątpliwości, czy jest to wiarygodny wskaźnik rzeczywistej halitozy

W odpowiedzi na te wyzwania, eksperci sugerują, że potrzebny jest standaryzowany protokół oceny halitozy w badaniach epidemiologicznych19. Jako złoty standard badań nad halitosą powinna być stosowana mechaniczna metoda wykrywania, na przykład halimetr (urządzenie mierzące stężenie związków siarki w wydychanym powietrzu)1916.

Czynniki ryzyka i przyczyny halitozy

Etiologia halitozy jest złożona i wieloczynnikowa20. Łańcuch etiologiczny halitozy wiąże się z obecnością substancji zapachowych w wydychanym powietrzu, szczególnie lotnych związków siarki (VSC) produkowanych przez bakterie12.

Przyczyny wewnątrzustne

Około 80-90% przypadków halitozy ma źródło wewnątrzustne2122. Główne czynniki ryzyka związane z jamą ustną obejmują:

  • Nalot na języku – jest to jeden z najważniejszych czynników ryzyka; grubszy nalot na języku zwiększa ryzyko halitozy920
  • Stan przyzębia – choroba przyzębia jest jedną z głównych przyczyn nieprzyjemnego zapachu z ust189
  • Próchnica zębów – osoby z próchnicą zębów mają 8,74 razy większe prawdopodobieństwo rozwoju halitozy niż pacjenci bez próchnicy15
  • Nieodpowiednia higiena jamy ustnej – jest to wiodąca przyczyna przewlekłej halitozy2322
  • Kserostomia (suchość jamy ustnej) – często spowodowana przez niektóre leki, odwodnienie i oddychanie przez usta22

Przyczyny zewnątrzustne

Chociaż rzadziej, halitoza może również wynikać z przyczyn pozaustnych i problemów ogólnoustrojowych24. Do najważniejszych czynników zewnątrzustnych należą:

Warto zauważyć, że wszystkie wymienione pozaustne przyczyny halitozy stanowią jedynie niewielki odsetek ogólnej liczby przypadków26.

Implikacje dla zdrowia publicznego

Halitoza stanowi istotny problem zdrowia publicznego ze względu na jej wysoką częstość występowania i wpływ na jakość życia11. Każdego roku Amerykanie wydają ponad 10 miliardów dolarów na produkty higieny jamy ustnej (gumy, płyny do płukania ust, pasty do zębów itp.) w celu zwalczania przewlekłej halitozy17.

Znaczenie edukacji i profilaktyki

Biorąc pod uwagę, że większość przypadków halitozy ma podłoże wewnątrzustne i jest związana z czynnikami, którym można zapobiec, edukacja w zakresie higieny jamy ustnej i profilaktyki odgrywa kluczową rolę31. Regularne wizyty kontrolne u dentysty połączone z dobrym programem higieny jamy ustnej mogą znacząco zmniejszyć częstość występowania przewlekłej halitozy22.

Badania wykazują, że większość osób zgłaszających, że regularnie szczotkują zęby, nadal ma halitosę, co wskazuje na potrzebę poprawy jakości, a nie tylko częstotliwości zabiegów higienicznych16.

Współpraca interdyscyplinarna

Ze względu na złożoną etiologię halitozy, uzasadnione jest organizowanie konsultacji w zakresie halitozy w środowisku multidyscyplinarnym, gromadzącym periodontologów, specjalistów ENT (laryngologów), specjalistów medycyny wewnętrznej oraz psychologów lub nawet psychiatrów24.

Osoby cierpiące na halitosę mogą być początkowo oceniane przez lekarza podstawowej opieki zdrowotnej (POZ)32. W przypadku podejrzenia przyczyn związanych z jamą ustną, lekarz POZ może skierować pacjenta do dentysty32. Wizyta u dentysty może pomóc wykluczyć chorobę przyzębia i zidentyfikować wszelkie problemy z jamą ustną, które mogą przyczyniać się do nieprzyjemnego zapachu z ust32.

W przypadku utrzymującej się halitozy, której przyczyna nie została zidentyfikowana lub wyeliminowana przez leczenie stomatologiczne, konieczne może być skierowanie pacjenta na odpowiednie leczenie medyczne33.

Trendy i prognozy

Wyniki badań sugerują ogólnoświatowy trend wzrostu częstości występowania halitozy4. Badania opublikowane po 2007 roku wykazują wyższą częstość występowania halitozy, co może być związane ze zmianami w nawykach żywieniowych, zwiększonym spożyciem alkoholu i stosowaniem przypraw jako środków aromatyzujących w żywności34.

W krajach o niskim i średnim dochodzie, wyższe wskaźniki choroby przyzębia mogą być powiązane z wyższą ogólną częstością występowania halitozy34. Sugeruje to, że poprawa opieki stomatologicznej i dostępu do usług zdrowotnych w tych regionach może przyczynić się do zmniejszenia występowania halitozy.

Wyzwania w badaniach nad halitosą

Pomimo dużej liczby publikacji na temat halitozy, niewiele wiadomo o jej epidemiologii i wpływie na jakość życia35. Trudności w przeprowadzaniu badań epidemiologicznych wynikają z różnic w metodologii, kryteriach diagnostycznych i definicjach halitozy36.

Potrzebne są dalsze badania wykorzystujące standardowe metody oceny i definicje, aby lepiej zrozumieć rozpowszechnienie halitozy w różnych populacjach i opracować skuteczne strategie jej zapobiegania i leczenia.

Rozpowszechnienie halitozy w różnych regionach świata

Podsumowanie danych epidemiologicznych

Halitoza stanowi powszechny problem zdrowotny, dotykający około jednej trzeciej populacji światowej54. Chociaż dokładne szacunki różnią się w zależności od regionu i metodologii badania, jasne jest, że halitoza ma znaczący wpływ na zdrowie publiczne i jakość życia osób nią dotkniętych11.

Większość przypadków halitozy (80-90%) ma źródło wewnątrzustne, co podkreśla znaczenie higieny jamy ustnej i regularnej opieki stomatologicznej w zapobieganiu i leczeniu tego schorzenia2131. Odpowiednia edukacja pacjentów, wczesna diagnostyka i multidyscyplinarne podejście do leczenia są kluczowe dla skutecznego zarządzania halitosą2433.

Istnieje potrzeba dalszych badań standardyzujących metodologię oceny halitozy, co pozwoli na bardziej dokładne porównania danych epidemiologicznych między różnymi populacjami i lepsze zrozumienie czynników wpływających na występowanie tego schorzenia19.

    https://www.ncbi.nlm.nih.gov/books/NBK534859/
    Halitosis is a term coined from the merger of the Latin halitus (breath) and Greek osis (pathological process) to describe a condition that meant an unpleasant odor from the mouth or bad breath, as we commonly call it. […] The quantum of data available on halitosis is fairly insufficient as there are no distinct criteria to define a bad odor and its extent for an individual. Hence, a lack of social and ethnic standardization of malodor is the main hindrance for carrying out scientific studies. […] Exact documentation of prevalence rates is difficult owing to the nonspecificity in defining a halitosis patient. Certain studies have shown the prevalence of halitosis up to 50%. Differences in prevalence values, however, would vary nationwide or community-wide due to differences in the method of the study.

    https://www.uptodate.com/contents/bad-breath
    Halitosis (from the Latin word for breath, “halitus”; also known as oral malodor, “fetor ex ore,” or“fetor oris”) is a common condition. Patients may not be aware of their own bad breath and learn of it from another person. […] This topic will cover the epidemiology, pathogenesis, causes, evaluation, and management of halitosis. […] Halitosis is defined as “malodor with intensity beyond a socially acceptable level perceived.” It is a significant concern for many individuals and may negatively affect their quality of life and personal relationships.
  • #3 Bad breath – Wikipedia
    https://en.wikipedia.org/wiki/Bad_breath
    Epidemiology: It is difficult for researchers to make estimates of the prevalence of halitosis in the general population for several reasons. Firstly, halitosis is subject to societal taboo and stigma, which may impact individuals’ willingness to take part in such studies or to report accurately their experience of the condition. Secondly, there is no universal agreement about what diagnostic criteria and what detection methods should be used to define which individuals have halitosis and which do not. Some studies rely on self reported estimation of halitosis, and there is contention as to whether this is a reliable predictor of actual halitosis or not. In reflection of these problems, reported epidemiological data are widely variable. […] Estimated rates of bad breath vary from 6% to 50% of the population. Concern about bad breath is the third most common reason people seek dental care, after tooth decay and gum disease. It is believed to become more common as people age.

    Halitosis (bad breath) is an unpleasant odour coming from the mouth that may originate from an oral or non-oral sources. It can be unpleasant enough to cause personal embarrassment. The reported prevalence estimates range from 2.4 to 78% with the American Dental Association reporting that 50% of American adults suffer. […] The main aim of this review was to assess the prevalence of halitosis in adults and adolescents. […] The estimated prevalence halitosis in the general population = 31.8% (95%CI; 24.639.0%) […] Prevalence in developed countries = 29.0% (95%CI; 21.236.8) and […] low-middle income countries = 39.8% (95% CI; 21.154.9) […] Our results demonstrated that the estimated prevalence of halitosis was 31.8%, with high heterogeneity between studies. The results suggest a worldwide trend towards a rise in halitosis prevalence.

    In a recent meta-analysis, the overall worldwide prevalence of halitosis was found to be 31.8%. […] Studies differ regarding gender and age differences and the prevalence of halitosis. […] It is well-recognized that individuals with halitosis may not perceive that they have halitosis and first learn of it from another person. […] Halitosis impacts social functioning, psychological well-being and overall quality of life.

    Studies show that 50 percent of adults have had bad breath, or halitosis, at some point in their lives. […] Bad breath that just wont go away or a constant bad taste in your mouth can be a warning sign of advanced gum disease, which is caused by a sticky, cavity-causing bacteria called plaque. […] Mouth infections can cause bad breath. However, if your dentist has ruled out other causes and you brush and floss every day, your bad breath could be the result of another problem, such as a sinus condition, gastric reflux, diabetes, liver or kidney disease. In this case, see your healthcare provider. […] If youre concerned about whats causing your bad breath, make an appointment to see your dentist. Regular checkups allow your dentist to detect any problems such as gum disease or dry mouth and stop them before they become more serious.

  • #10 Self-perceived halitosis and associated factors among university students in Dhaka, Bangladesh | BMC Oral Health | Full Text
    https://bmcoralhealth.biomedcentral.com/articles/10.1186/s12903-024-04586-y
    Bad breath (halitosis) is a common problem affecting psycho-social wellbeing of young people. We aimed to explore the extent of self-perceived halitosis and associated factors among university students in Dhaka, Bangladesh. A total of 55.97% of students had self-perceived halitosis, with females (74.53%) having a significantly higher proportion than males (36.94%) (p0.001). A significantly higher proportion of halitosis was found among participants who were overweight (61%), had obesity (60.77%), smoked cigarette (46.79%), consumed alcohol (71.43%), lacked exercise (66.29%), were on unhealthy diet (57.35%), consumed coffee/tea (61.35%), breathed through mouth (64.60%), brushed tooth infrequently (85.71%), changed toothbrush after 6 months (77.42%), did not use toothpaste (94.74%), did not use/ sometimes used fluoride toothpaste (75.76%), lacked dental floss use (60.85%), did not use toothpick (62.87%), did chew or sometimes chewed sugar-free chewing gum (75.82%), did not clear / cleaned tongue sometimes (76.14%), did use mouth freshener regularly or occasionally (64.97%), did not use or used mouthwash sometimes (58.87%) were also associated with higher self-perceived halitosis (p0.05 for all). This study reveals a high proportion of self-perceived halitosis and relevant factors. There should be more public education on the causes of halitosis and potential management approaches. Globally, many people suffer from halitosis. An estimated 31.8% of the general population (95% CI 24.639.0%) were found to suffer from halitosis in 2017. However, due to the lack of an accepted definition of halitosis, the subjective nature of reporting, and the different methodologies used, there is much heterogeneity in the reporting of its prevalence across the globe. In Bangladesh, the only study exploring halitosis was among women in Dhaka city, where the prevalence of halitosis was found to be 75%. Self-perceived halitosis (SPH) represents a prevalent oral health concern transcending demographic boundaries. Beyond its apparent social implications, SPH exerts considerable influence on individuals quality of life. Particularly within the university milieu, where academic pursuits intertwine with social dynamics, the impact of SPH extends beyond mere discomfort, potentially affecting academic performance and interpersonal relationships. Therefore, this study aimed to assess SPH and its associated factors among Bangladeshi university students. Our study found that approximately 55.97% of the participants reported self-perceived halitosis. This finding is consistent with previous research conducted in India and Saudi Arabia among comparable populations, where the prevalence of self-reported halitosis ranges from 40 to 60%. Additionally, several former studies have investigated the prevalence of SPH, revealing varying rates across different regions and demographics. For instance, studies conducted in North America, Europe, Asia, and other regions have documented SPH prevalence rates spanning from approximately 20% to over 60%, highlighting the widespread nature of this oral health concern. Furthermore, research suggests that SPH is not confined to specific geographic regions or socioeconomic statuses but affects individuals across diverse populations globally.

    Older adults are more vulnerable to dry mouth one of the leading causes of bad breath and they may find it difficult to maintain proper oral hygiene as they age, says geriatrics medicine specialist Taryn Lee, MD. […] Bad breath also could be a sign that an older adult is having difficulty caring for themselves, Dr. Lee says. […] I worry more about bad breath because it may be a sign of other geriatric problems,” Dr. Lee says. „Things that we take for granted sometimes aren’t that easy for our older patients to do. […] Saliva helps wash away bacteria that can lead to bad breath. As we age, we not only produce less saliva, we are also more likely to be on medications or combinations of medicines that can cause dry mouth. […] Fortunately, bad breath is rarely an issue for older adults who practice good oral hygiene, avoid tobacco and alcohol, eat a healthy diet and drink plenty of fluids.
