Antimicrobial Treatment of Periodontal Diseases
U ovom se Älanku ocjenjuje vrijednost sustavne protumikrobne terapije bolesti parodonta. Poznavati tip parodontne infekcije može biti važno u izboru protumikrobne terapije. Protumikrobno lijeÄenje treba prilagoditi razlikama u osjetljivosti na antibiotike pojedinih parodontnih patogena.
U literaturi je opisano mnogo razliÄitih vrsta antibiotske terapije Å”to otežava odluku o izboru antibiotika u kliniÄkoj praksi. Vrijednost sustavne upotrebe antibiotika u zaustavljanju progresije parodontnih bolesti ispitana je u mnogobrojnim studijama. Glavni kandidati za antibiotsku terapiju jesu pacijenti kojima konvencionalnom mehaniÄkom terapijom nije zaustavljeno napredovanje bolesti. Opravdana je upotreba i u bolesnika s lokaliziranim agresivnim parodontitisom ili drugim rano razvijenim oblicima bolesti, te u pacijenata sa sustavskim bolestima koje utjeÄu na parodontitis. Dokazano je da kao dodatak uobiÄajenoj terapiji može poboljÅ”ati ishod lijeÄenja. Ozbiljne nuspojave koje sa sobom donosi sustavna uporaba antibiotika, kao Å”to su razvoj rezistencije, te porast oportunistiÄkih mikroorganizama, ne opravdavaju rutinsku uporabu antibiotika u lijeÄenju kroniÄnih, sporoprogredirajuÄih oblika parodontnih bolesti.This paper presents a critical evaluation of the use of systemic antimicrobial treatment in periodontal disease. Recognizing specific types of periodontal infections can significantly influence the choice of antimicrobial treatment. Therapy should be tailored to differences in antibiotic susceptibility between various periodontal pathogens.
Many different antibiotic regimens have been described in the literature, making the choice in clinical practice difficult. Numerous studies have examined the impact of systemic antibiotic treatment in stopping the progression of periodontal diseases. Major candidates for antibiotic therapy are patients whose disease continues to progress despite conventional mechanical treatment. Antibiotics can also be used in patients with localized aggressive or other early developed forms of periodontitis, as well as in patients with systemic diseases affecting the course of periodontitis. They have proven to be beneficial as an adjunct to standard therapy. Serious side-effects of systemic antibiotic treatment, such as development of resistance and increase in opportunistic microorganisms, do not justify their use in the treatment of chronic, slowly-progressive forms of periodontal diseases
Comparison of Periodontal Health in Two Different Rural Population Types in Croatia
Planinsko selo ima manji stupanj parodontne bolesti i gubitka priÄvrstka od primorskoga sela. Usporedba parodontnog zdravlja i potreba tretmana izmeÄu primorske i planinske seoske sredine uÄinjena je na uzorku od 441 osobe (40% populacije) dobi iznad 15 godina uporabom Parodontnog indeksa zajednice (CPI) i indeksa Gubitka priÄvrstka (LA). Prevalencija parodontne bolesti u u objema sredinama vrlo je visoka. Gingivitis i parodontitis javljaju se vrlo rano. Prevalencija zdravog parodonta nije zabilježena iznad 30. godine ni u primorskoj ni u planinskoj sredini. Plitiki parodontni džepovi postoje veÄ u adolescenata u primorju 11,76% (p < 0,05), a u planini od 20. godine - 14, 26%. Iznad 30. godine u objema sredinama viÅ”e od 50% populacije ima plitki ili duboki džep, a iznad 55. godine oko 40% obiju populacija ima registriran barem jedan duboki džep. IskljuÄenih sekstanata u svim dobnim skupinama ima planinsko selo i to u rasponu od 2 do 11 puta viÅ”e (p < 0,05). U objema populacijama viÅ”e od 4 sekstanta je iznad 65. godine iskljuÄeno. Zbog manjega broja preostalih zubi planinsko selo ima i manji stupanj parodontne bolesti.
ViÅ”e od 50% populacija iznad 35. godine ima gubitak priÄvrstka > 6mm (prosjeÄno u 1 sekstantu). Iznad 45. godine gotovo da i nema sekstanata s gubitkom priÄvrstka < 3mm. ViÅ”e od 90% ispitanika obaju podruÄja treba neku vrstu parodontnog tretmana.The rural population in mountain region has less periodonal disease and attachment loss degree. A comparison of periodontal health and necessary treatment between the littoral and rural populations in mountain region was conducted on a sample of 441 individuals (40% of the population) in the 15+ age group, by applying the Community Periodontal Index (CPI) and the Loss of Attachment Index (LA). The prevalence of periodontal disease in both areas appears to be very high. The occurrence of gingivitis and parodontitis is evident at an early age. Neither in the littoral nor in the mountains region was the prevalence of healthy periodont in the 30+ age group recorded. In the littoral area shallow periodontal pockets are already present with adolescents - 11.76% (p<0.05), and in the mountain region from the age of 20 - 14.26%. More than 50% of the 30+ population of both regions has either deep or shallow pockets, while approximately 40% of the 55+ population in both groups has at least one deep pocket. The mountain village has excluded sextants in all age groups, ranging from 2 to 11 times more then the littoral village (p<0.05). In the 65+ group of both populations more than 4 sextants are excluded. Because of the smaller number of remaining teeth, the mountain village records less periodontal disease.
More than 50% of the 35+ age group has loss of attachment >6mm (approximately in one sextant). In the 45+ age group there is almost no sextant with loss of attachment <3mm. More than 90% of the examinees in both regions need some kind of periodontal treatment
Therapy of Advanced Periimplantitis - Case Presentation Clinical and Microbial Results after 10 Months
Sve viÅ”e bude postavljenih usadaka neizbježno je da Äe biti viÅ”e komplikacija u vezi s takvim terapijskim postupkom. Jedna od komplikacija koju je najteže izlijeÄiti i koja posljediÄno može dovesti do gubitka usatka jest bakterijski uzrokovan periimplantitis. U ovome prikazu sluÄaja opisat Äe se uspjeÅ”na terapija uznapredovala periimplantitisa. Pacijent u dobi od 58 godina poslan je parodontologu zbog smetnji u usnoj Å”upljini u obliku neugodna zadaha te gnojenja oko zuba i usadaka. Prigodom parodontoloÅ”koga pregleda opaženo je da su oba usatka na mjestima 22 i 25 zahvaÄena periimplantatnim mukozitisom te da postoji krvarenje i gnojenje pri sondiranju. Kod usatka u podruÄju 25 postojao je i problem potpunoga nedostatka keratinizirane gingive. Na temelju kliniÄkog i rtg nalaza te pozitivnog mikrobioloÅ”og nalaza na parodontopatogene dijagnosticiran je periimplatitis oko oba usatka. Inicijalna parodontoloÅ”ka terapija zavrÅ”ena je u Äetiri posjeta. Pacijent je dobio upute kako da održava oralnu higijenu te je ukljuÄena antiseptiÄka terapija, ispiranje klorheksidinom i uporaba klorheksidinskoga gela izravno u džepove oko usadaka. Kako i nakon takve terapije gnojenje nije prestalo, ukljuÄena je i antibiotska terapija te ispiranje džepova jodom. Nakon Å”to je infektivni proces uspjeÅ”no stavljen pod nadzor, u daljnjem terapijskom postupku proveden je parodontoloÅ”ki kirurÅ”ki zahvat kako bi se oko usatka 25 pokuÅ”ao ispraviti nedostatak keratinizirane gingive i dobiti nov priÄvrstak. PoÅ”to je režanj odignut, povrÅ”ina usatka oÄiÅ”Äena je sterilnom vatom natopljenom u klorheksidin, a s nepca je uzet vezivni presadak te je postavljen na kosti i na izložene navoje usatka. Preko presatka postavljen je Gengigel (hijaluronska kiselina) radi boljeg cijeljenja rane. Pet mjeseci nakon operacije ponovljena je mikrobioloÅ”ka raÅ”Älamba te viÅ”e nije bilo parodontnih patogena, a kliniÄka mjerenja su pokazala da je smanjena dubina sondiranja, da ne postoji krvarenje ili gnojenje i da je nastala zona keratinizirane gingive od 2 mm oko usatka 25.With the ever increasing number of placed implants it is inevitable that the number of complications connected with such therapeutic procedure will also increase. One of the complications which is hardest to treat and which consequently can lead to loss of the implant, is bacterial caused periimplantitis. This case presentation describes the successful therapy of advanced periimplantitis. The male patient, aged 58 years, was referred to the periodontist because of problems in the oral cavity in the form of unpleasant breath and suppuration around the tooth and implant. During the periodontal examination it was observed that both implants on places 22 and 25 were affected by periimplantic mucositis and bleeding and suppuration occurred during probing. With regard to the implant in area 25 the problem of complete loss of keratinised gingiva was also present. On the basis of the clinical and X-ray findings, and positive microbial test for periodontopathogens, periimplantitis was diagnosed around both implants. Initial periodontological therapy was carried out in four visits. The patient received instructions on the maintenance of oral hygiene and antiseptic therapy was included, rinsing with chlorhexidine and application of chlorhexidine gel directly into the pockets around the implants. As after this therapy the suppuration did not stop antibiotic therapy was included, with rinsing of the pockets with iodine. After successful control of the infective process, further therapy involved a periodontological surgical operation in order to correct the loss of keratinised gingiva around implant 25 and to obtain new attachment. After lifting the flap the surface of the implant was cleaned with sterile cotton wool soaked in chlorhexidine, and from the palate a connective transplant was taken and placed on the bone and the exposed thread of the implant. Gengigel (hyaluronic acid) was placed over the transplant for better healing of the wound. Five months after the operation microbial analysis was repeated. Periodontal pathogens were no longer present and clinical measurements showed reduced probing depth, absence of bleeding and suppuration, and the occurrence of zones of keratinised gingiva of 2 mm around implant 25
Oralna higijena kao važan Äimbenik u sprjeÄavanju pneumonije povezane s mehaniÄkom ventilacijom
Inadequate oral hygiene in intensive care units (ICUs) has been recognized as a critical issue, for it is an important risk factor for ventilator associated pneumonia (VAP). VAP is an aspiration pneumonia that occurs in mechanically ventilated patients, mostly caused by bacteria colonizing the oral cavity and dental plaque. It is the second most common nosocomial infection and the leading cause of complications and death in mechanically ventilated patients. It has been suggested that improvement of oral hygiene in ICU patients could lead to a reduced incidence of VAP. Although diverse oral care measures for ICU patients have been proposed in the literature, there is no evidence that could identify the most efficient ones. Although there are several evidence-based protocols, oral care measures are still performed inconsistently and differ greatly between individual ICUs. This paper lists the oral care measures most commonly performed in ICUs, indicating their advantages and disadvantages. Brushing with regular toothbrush and rinsing with chlorhexidine are considered optimal measures of oral hygiene in critically ill patients. To date, there is no definitive agreement about the most effective oral care protocol, but evidence demonstrates that consistent performance of oral care may lower the incidence of VAP in critically ill patients.NezadovoljavajuÄa oralna higijena na jedinicama intenzivnog lijeÄenja (JIL ) prepoznata je kao kljuÄno pitanje, jer predstavlja znaÄajan Äimbenik rizika za razvoj pneumonije povezane s mehaniÄkom ventilacijom. Pneumonija povezana s mehaniÄkom ventilacijom je aspiracijska pneumonija koja se javlja kod mehaniÄki ventiliranih bolesnika i veÄinom je uzrokovana bakterijama koje koloniziraju usnu Å”upljinu i zubni plak. Druga je po redu najÄeÅ”Äa nozokomijalna infekcija i vodeÄi je uzrok komplikacija i smrti u mehaniÄki ventiliranih bolesnika. Smatra se kako bi poboljÅ”anje oralne higijene u JIL moglo rezultirati smanjenom incidencijom pneumonije povezane s mehaniÄkom ventilacijom. Iako su u literaturi predložene razne mjere oralne higijene za bolesnike u JIL , ne postoje dokazi koji bi pokazali koje su od njih najuÄinkovitije. Iako postoji nekoliko protokola temeljenih na dokazima, mjere oralne higijene se joÅ” uvijek provode nedosljedno i razlikuju se meÄu pojedinim JIL . Ovaj rad navodi mjere oralne higijene koje se najÄeÅ”Äe provode u JIL i ukazuje na njihove prednosti i nedostatke. Optimalnim mjerama oralne higijene smatraju se Äetkanje obiÄnom zubnom Äetkicom i ispiranje klorheksidinom. Iako do danas ne postoji suglasje o najuÄinkovitijem protokolu oralne skrbi, pokazalo se kako dosljedno provoÄenje oralne higijene može smanjiti incidenciju pneumonije povezane s mehaniÄkom ventilacijom u kritiÄno bolesnih pacijenata
Quantitative Analysis of Candidiasis and Pyrosis in Oral Lichen Ruber
Retrospektivnim istraživanjem elaborirani su svi sluÄajevi OLR-a u pacijenata koji su doÅ”li na lijeÄenje u Zavod za oralnu medicinu StomatoloÅ”kog fakulteta SveuÄiliÅ”ta u Zagrebu u razdoblju od 1. sijeÄnja 1995 do 31. prosinca 1998 godine. Svrha rada bila je utvrditi ÄestoÄu infekcije Candidom albicans i postojanje piroze u pacijenata s OLR-om. ProsjeÄna starost žena je 55 godina, muÅ”karaca 53. U žena je OLR bio u dvostruko veÄoj frekvenciji nego u muÅ”karaca (66,6 : 33,3 %). NajÄeÅ”Äe se OLR javljao izmeÄu 40 i 60. godina života. NajÄeÅ”Äa je forma OLR planus (69%). U 75 pacijenata ili 43,1% od ukupno 174 OLR naÄena je kandidijaza, a simptom piroze postojao je u 62 pacijenta ili 35,6%. Pacijenata samo s kandidijazom bez piroze bilo je 39 ili 22,4%, samo s pirozom bez kandidijaze 26 ili 14,9%, a s kandidijazom i pirozom 36 ili 20,7%. Zbog tako visoke ÄestoÄe infekcije Candidom albicans i postojanja simptoma piroze, kada su dijagnosticirani, u terapijskim postupcima OLR-a treba lijeÄiti i kandidijazu i pirozu.All oral lichen ruber (OLR) cases seen at the Department of Oral Medicine, School of Dental Medicine University of Zagreb, from January 1, 1995 to December 31, 1998, were included in this retrospective study. The aim of the study was to assess the prevalence of Candida (C. albicans) infection and burning mouth syndrome (BMS) in OLR patients. The mean age of the examined men and women was 53 and 55 years, respectively. In women, the prevalence of OLR was twice as high as in men (66.6% : 33.3%). OLR most commonly occured between the age of 40 and 60 years. The most frequent type of OLR was lichen planus (69%). C. albicans was detected in 75 of 174 (43.1%) patients, while BMS was present in 62 (35.6%) patients. There were 39 (22.4%) patients with candidiasis (without BMS), 26 (14.9%) with BMS (without candidiasis), and 36 (20.7%) with both candidiasis and BMS. The high prevalence of C. albicans infection and BMS concurrence indicates to the need for simultaneous treatment of both entities
Radiographic and Prosthetic Assessment Prior to Implantoprosthetic Therapy
Jedan od osnovnih uvjeta uspjeÅ”nosti terapije oseointegrirajuÄim usadcima jest dobro predkirurÅ”ko planiranje. Svrha je ovoga rada prikazati na sluÄaju djelomiÄne bezubosti u distalnom dijelu mandibule moguÄnosti radioloÅ”ke i protetske ocjene prije kirurÅ”koga tretmana. Na modelu Äeljusti uÄinjeno je dijagnostiÄko navoÅ”tavanje. Nakon toga izraÄena je Å”ablona iz vakuum termoplastiÄne folije. Metalne kuglice poznatoga promjera stavljene su u pozicije navoÅ”tanih zuba kako bi se radioloÅ”kom tehnikom ocijenila moguÄnost implantacije u predviÄenim pozicijama. UÄinjen je klasiÄni ortopantomogram te na temelju njega i slojeviti tomogram s toÄnim presjecima mandibule na položajima buduÄih usadaka. Na temelju rendgenskih nalaza odreÄen je položaj i duljina usadaka. Prikazan je klasiÄan dvofazni kirurÅ”ki protokol te operacijska tehnika s intraoralnim pretprotetskim Å”ablonama. Uporabljeni su usadci Astratech microthread koniÄnoga profila kako bi se promjerom usatka Å”to viÅ”e približili promjeru buduÄega zuba. Dužina usatka odreÄena je u skladu s navedenom radioloÅ”kom raÅ”Älambom tako da je usadak na poziciji 35 kraÄi od usadaka 34 i 37 zbog anatomske pozicije foramena mentale. Pri kirurÅ”kome pozicioniranju usatka osim pozicije koja je odreÄena Å”ablonom usadci su u okomitome smjeru pozicionirani u skladu s bioloÅ”kom Å”irinom sluznice i u konaÄnici parodontoloÅ”ko estetskim zahtjevima. Rezultati prikazuju uspjeÅ”nost terapije nakon dobra planiranja i pripreme. Prikazana je prednost slojevite tomografije u planiranju i odreÄivanju anatomsko-morfoloÅ”kih karakteristika donje Äeljusti koja nam daje sigurnost u izboru dužine, a osobito Å”irine usatka. PredkirurÅ”ko planiranje je postupak kojime možemo predvidjeti položaj usatka i estetiku buduÄega protetskog rada te tako olakÅ”ati kirurÅ”ki zahvat.One of the fundamental pre-conditions for successful therapy by osseo-integrating implants is good pre-surgical planning. The aim of this work is to present the possibilities of radiographic and prosthetic evaluation prior to surgical treatment in the case of partial edentulousness.in the distal part of the mandibula. Diagnostic wax-up is done on a model of the jaw. After which a pattern is made of vacuum thermoplastic foil. Metal pellets of known diameter are placed in the positions of the waxed-up teeth to enable radiographic evaluation of the possibility of implantation in the planned positions. Classical orthopantomography is performed on the basis of which a multi-layer tomogram is done with exact cross-sections of the mandibula in the positions of future implants. On the basis of radiographic findings the position and length of the implants are determined. The classical two-phase surgical protocol is described and surgical technique with intraoral pre-prosthetic patterns. Astratech microthread implants of conical profile are used to ensure that the implant diameter is as close as possible to the diameter of the future tooth. The length of an implant is determined in accordance with the cited radiographic analysis, so that the implant in position 35 is shorter in relation to implants 34 and 37, due to the anatomic position of the foramen mentale.
During surgical positioning of implants, apart from the position which is defined by the pattern, in the vertical direction the implants are positioned in accordance with the biological width of the mucous membrane and finally with periodontal aesthetic requirements. The results show the success of the therapy following good planning and preparation. The advantage is shown of multi-layer tomography in planning and determining the anatomical-morphological characteristics of the lower jaw, which provides assurance in the choice of length and particularly the width of the implant. Pre-surgical planning is a procedure by which it is possible to foresee the position of an implant and aesthetics of future prosthetic work, and thus to facilitate the surgical intervention
The Distribution of Periodontal Disease and Loss of Attachment in Jaw Sextants in Different Age Groups ā CrossāSectional Study
The distribution of periodontal disease stages is not the same in both human jaws,
parts of the same jaw or in different ages of life. In the sample of 2,730 sextants, 455 persons
15+ years of age, analysis of distribution of both periodontal disease and loss of attachment
in jaw sextants in different age groups was made, using the Community Periodontal
Index (CPI) and Loss of Attachment (LA). Statistical significance testing was
checked using the Pearson Chi-Square-test with probability of 95%. Healthy periodontium
is mostly found in upper anterior sextant (36%, p < 0.001), and bleeding on
probing in lower right sextant (25.45%, p < 0.001). There is most calculus in lower anterior
sextant (48.19%, p < 0.001), followed by upper posterior (15ā17%). Deep pockets are
more often in lower anterior sextant (31.87%, p < 0.001), and upper and lower posterior
sextants are without teeth in 18ā20.5% of cases, but lower anterior sextant in only 7.73%
(p < 0.001). Cumulative minimal loss of attachment (0ā3 mm) significantly is more often
present in upper anterior sextant (21.2%, p < 0.001), while values 5ā11 mm are more
often in lower anterior sextant (25ā43%, p < 0.001). Loss of attachment 12mm appears
in only 1.4% present sextants and it is rear on left jaw side. Significant differences in
distribution of both periodontal disease and loss of attachment appear in age 30+
Parodontne bolesti kao Äimbenik rizika
There is an increasing body of evidence in periodontology that speaks in favor of the association between human chronic inflammatory diseases and opportunistic infections. Considering their frequency and microbiological etiology, periodontal diseases, especially severe periodontitis, have become subjects of many studies. Periodontitis is a major infectious threat to the whole organism, since it can affect distant organs and tissues by releasing microbes, their products and mediators of inflammation into the bloodstream. This fact has reduced the boundaries between medicine and dentistry, but the change in thinking has developed an entirely new field of periodontology, also known as āperiodontal medicineā.
Over the past decade a growing body of scientific evidence shows a strong connection between periodontal disease and systemic conditions and diseases such as atherosclerosis, cardiovascular and cerebrovascular diseases, premature birth, diabetes and respiratory diseases. Most of the research has been focused on the relationship between periodontal disease and atherosclerosis since they have many common, potential pathophysiological mechanisms, including complex etiology, and share many risk factors, especially smoking history. There is data linking periodontitis with an increased risk for atherosclerosis and thromboembolic events. Periodontitis in pregnant women may increase the risk for preterm birth and low birth-weight. The role of diabetes as a risk factor for periodontal disease has been investigated earlier, but a number of studies suggest that there may be a two-way relationship, in accordance with the concept that infection may weaken metabolic control of diabetes.
The results of numerous studies and the development of periodontal medicine have led to productive cooperation with colleagues in medicine, and discovered many new evidences that suggest that the oral cavity is an integral part of the human body, and that systemic health must include oral and periodontal health.Sve je viÅ”e dokaza koje govore u prilog povezanosti kroniÄnih upalnih bolesti Äovjeka s oportunistiÄkim infekcijama u parodontologiji. Parodontne bolesti, posebice uznapredovali parodontitis, postale su predmet mnogobrojnih istraživanja s obzirom na uÄestalost i mikrobioloÅ”ku etiologiju. Parodontitis predstavlja veliku infektivnu opasnost za cijeli organizam jer otpuÅ”tajuÄi mikroorganizme, njihove produkte te medijatore upale u krvotok može djelovati na udaljene organe i tkiva. Navedena Äinjenica smanjila je granice izmeÄu medicine i stomatologije te je promjenom razmiÅ”ljanja doÅ”lo do razvoja potpuno novog podruÄja u parodontologiji koje je nazvano āparodontna medicinaā. Tijekom proÅ”log desetljeÄa sve veÄi broj znanstvenih Äinjenica upuÄuje na snažnu povezanost parodontnih bolesti i sistemnih stanja i bolesti kao Å”to su: ateroskleroza, kardiovaskularne i cerebrovaskularne bolesti, prijevremeni poroÄaj, dijabetes i pluÄne bolesti. NajviÅ”e istraživanja bilo je usmjereno na povezanost izmeÄu parodontitisa i ateroskleroze s obzirom da imaju mnogo zajedniÄkih, potencijalnih patofizioloÅ”kih mehanizama, kompleksne su etiologije te dijele brojne riziÄne faktore, meÄu kojima je najznaÄajniji status puÅ”aÄa. PronaÄeni su dokazi koji povezuju parodontitis s poveÄanim rizikom za aterosklerozu i tromboemboliÄkim zbivanjima. Parodontitis trudnica može poveÄati rizik za prijevremeno roÄenje i smanjenu poroÄajnu težinu djeteta. Uloga dijabetesa kao faktora rizika za parodontitis istražena je ranije, ali odreÄen broj studija ukazuje da možda postoji i dvosmjerni odnos, u skladu s koncepcijom da infekcija može doprinijeti oslabljenoj metaboliÄkoj kontroli dijabetesa. Rezultati mnogobrojnih studija i razvoj parodontne medicine doveli su do plodonosne suradnje s kolegama u medicini i otkrili mnoga nova saznanja koja potvrÄuju da je usna Å”upljina integralni dio ljudskog tijela te da sistemsko zdravlje mora ukljuÄivati oralno i parodontno zdravlje
Unrealistic Optimism and Demographic Influence on Oral Health-Related Behaviour and Perception in Adolescents in Croatia
Znanje i motivacija smatraju se osnovnim odrednicama zdravstveno-higijenskih navika. U ovom radu željeli smo prouÄiti utjecaj demografskih karakteristika, percepcije, motivacije i educiranosti adolescenata na oralno zdravlje i njihove oralnohigijenske navike. Ispitivanje je provedeno anonimno, anketnim upitnikom godine 2006. na uzorku od 302 srednjoÅ”kolca u dobi od 17 do 19 godina, u tri grada u razliÄitim regijama koriÅ”tene su neparametrijske statistiÄke metode za analizu podataka. Percepcija adolescenata o oralnom zdravlju na visokoj je razini, za razliku od niske percepcije oralnih bolesti. Iako razliÄiti demografski, socijalni i spolni Äimbenici utjeÄu na oralnohigijenske navike, na njih manje utjeÄe znanje adolescenata. Pa Äak i oni s veÄim znanjem o oralnim bolestima i prevenciji, nisu ÄeÅ”Äe primjenjivali osnovne higijenske navike, niti su se ÄeÅ”Äe koristili pomoÄnim sredstvima, mijenjali Äetkicu, posjeÄivali
stomatologa ili izbjegavali Å”eÄer. OÄito je da adolescenti ne izvlaÄe smisao iz informacija o riziku za vlastito zdravlje, niti mogu jednostavno prepoznati vezu vlastita ponaÅ”anja i rizika kojem se izlažu. To je povezano s nerealnim optimizmom i tendencijom da se negativni dogaÄaji uoÄavaju rjeÄe, a pozitivni ÄeÅ”Äe na sebi nego na drugima.Knowledge and motivation are considered to be essential determinants of health-related behaviour. The aim of this study was to evaluate the influence of demographic characteristics, perception, knowledge and motivation regarding oral health of adolescents on their habits in oral hygiene. The study was conducted in 2006 in the
sample of 302 secondary school students, aged 17 to 19, from three cities in different Croatian regions using a questionnaire. Data were analysed by nonparametric statistics. Adolescents have relatively high perception regarding oral health, but their perception of oral diseases is quite low. Although different demographic, social and gender-related factors affect oral health behaviours, they are less affected by adolescentsā knowledge. And in fact those who were better educated about oral diseases and prevention didnāt practice basic hygiene significantly more often, nor used additional products, changed their toothbrush, visited dentist or avoided sugar. It is obvious that young people do not draw personal implications from health risk information, or can not easily recognise the link between their own behaviour and the risk they are putting themselves into. It has been related to unrealistic optimism, the tendency to perceive negative events as less likely and positive events as more likely to oneself than to others
