Tooth Wear Related Signs in the Croatian Navy Employees

Abstract

Svrha: U ovom se istraživanju željelo odrediti stupanj trošenja zuba kod pripadnika Hrvatske ratne mornarice te procijeniti oralne znakove i demografske čimbenike povezane s tim procesom. Materijali i postupci: Uzorak se sastojao od 1092 pripadnika Hrvatske ratne mornarice u dobi od 20 do 60 godina (srednja dob 37,06±7,85) i to 985 muškaraca i 107 žena. Mjerenje iznosa trošenja zuba temeljilo se na relativnom stupnju nalaza brusnih faseta (ljestvica 0 – 4). Ukupno trošenje zuba (iznos zbroja svih brusnih faseta) i indeks trošenja zuba (prosječan godišnji porast zbroja svih faseta korigiran za postotak zuba koji nedostaju) korelirani su s demografskim podacima, hipertrofijom žvačnih mišića i njihovom napetošću nakon buđenja, pomičnošću zuba, lineom albom, impresijama na jeziku, bukalnim ranicama, nekarijesnim cerviksnim lezijama (NKCL-om), brojem zuba i anamnestičkim podatkom o bruksizmu kako bi se odredile specifične povezanosti tih varijabli s trošenjem zuba. Rezultati: Postotak zuba s okluzijskim trošenjem bio je od 21,66 posto u najmlađoj dobnoj skupini do 52,45 posto u najstarijoj. Ukupno trošenje zuba bilo je najjače izraženo kod ispitanika u najstarijoj dobnoj skupini, a najmanje kod najmlađih. Linearna multipla regresijska analiza pokazala je da je povećano trošenje zuba bilo značajno povezano s NKCL-om (β=0,55, p<0,001), impresijama na jeziku (β=0,17, p<0,001), muškim spolom (β=-0,105, p<0,001), mišićnom napetošću (β=0,103, p<0,05) i hipertrofijom mišića (β=0.063, p<0.05). Koeficijent determinacije (R2) modela iznosio je 0,49. Zaključak: Rezultati ovog istraživanja upućuju na to da su NKCL, impresije na jeziku, napetost mišića, muški spol i hipertrofija mišića potencijalni čimbenici koji pokazuju najveću povezanost s trošenjem zuba. Nije pronađena znatna povezanost između indeksa trošenja zuba i linee albe, pomičnsti zuba, bukalnih ranica i anamnestičkog podatka o bruksiranju.Objective: The objective of this study was to determine the severity of tooth wear in a sample of Croatian navy employees and to evaluate oral signs and demographic factors related to it. Materials and Methods: The sample included 1092 navy employees aged 20 to 60 years (mean age 37.06±7.85), 985 men and 107 women. The tooth wear severity measurements were based on the relative degree of faceting (0-4 scale). The tooth wear score (the sum of all facets scores) and tooth wear index (average annual growth of sum of ratings corrected for the percent of missing teeth) were correlated to demographic data, masticatory muscles hypertrophy, masticatory muscles tension upon awakening, tooth mobility, linea alba, tongue indentations, traumatic ulcers, noncarious cervical lesions (NCCL), number of teeth and self-reported bruxism in order to determine the specific correlates of tooth wear. Results: The percentage of teeth with occlusal wear ranged from 21.66% in the youngest age group to 52.45% in the oldest age group. The tooth wear score was highest in 40-60-year-old subjects, and lowest in 20-30-year-old subjects. The stepwise multiple linear regression analysis showed that increased tooth wear was significantly associated with NCCL (ß=0.55, p<0.001), tongue indentations (ß=0.17, p<0.001), male gender (ß=- 105, p<0.001), muscle tension (ß=0.103, p<0.05), and muscle hypertrophy (ß=0.063, p<0.05). The R² of the model was 0.49. Conclusion: The results of this study suggest that NCCL, tongue indentations, muscle tension, male gender and muscle hypertrophy are potential factors that may influence or predict tooth wear. There was no significant relationship or association between tooth wear index and linea alba, tooth mobility, traumatic ulcers and self report of bruxism
