Abstract
Svrha: Želio se procijeniti intenzitet dentinske preosjetljivosti prije postupaka supragingivne i subgingivne instrumentacije i nakon njih. Materijal i metode: Bio je odabran prikladan uzorak od 200 ispitanika obaju spolova u dobi od 18 do 71 godine, a dijagnosticiran im je bio marginalni gingivitis, gingivna recesija i umjeren i/ili izrazit kronični parodontitis. Preosjetljivost je ustanovljena kliničkim pregledom te izmjerena mehanički provlačenjem sonde preko izloženog dentina i toplinskim podražajima – mlazom zraka iz pustera na osjetljivim područjima. Rezultati: Otkriveno je nekoliko vrsta preosjetljivosti kod istog pojedinca, a najčešća je bila preosjetljivost dentina u području korijena zuba. Najviše ispitanika bolovalo je od kroničnog parodontitisa, najčešće su imali više od pet preosjetljivih zuba, a povećana preosjetljivost bila je zabilježena nakon supragingivne i subgingivne instrumentacije. Sekundarni čimbenici koji su pojačavali osjetljivost i sve varijable vezane uz preosjetljivost, statistički su značajni (p<0,05). Zaključak: Preosjetljivost je česta kod pacijenata s parodontnom bolešću, a izraženija je nakon inicijalne parodontne terapije te kada je udružena s ostalim lokalnim čimbenicima.Objective: To evaluate the intensity of dentin hypersensitivity before and after the procedures of supragingival and subgingival instrumentation. Method: The convenience sample consisted of 200 patients of both genders, aged 18-71 years, who had chronic marginal gingivitis, gingival recession and moderate and/or severe chronic periodontitis. The hypersensitivity was diagnosed by clinical examination and measured by means of mechanical (dragging the probe over the exposed dentin) and thermal (air blast from a triple syringe) stimuli in sensitive areas. Results: The data revealed several types of hypersensitivity in the same individual, with the highest percentage in the tooth root; the largest percentage in the sample had chronic periodontitis; most patients had more than five hypersensitive teeth; increased hypersensitivity was found after supragingival and subgingival instrumentation; the presence of secondary factors exacerbating the sensitivity was recorded; and all variables associated with hypersensitivity had statistical significance
(p <0.05). Conclusion: It is concluded that hypersensitivity is a common condition in patients with periodontal disease, which is more pronounced after initial periodontal therapy and when associated with other local factors
