Abstract (english)

Objective:

The objective of the study was to establish whether there is a difference in the presence of potentially pathogenic anaerobic microorganisms around the implant and the homologous tooth in implant-prosthetic patients who received individual information about maintaining their oral hygiene. -----

Material and methods:

The study included 30 subjects with dental implants and metal-ceramic crowns. A periodontal probe was used to record the approximal plaque index (API), the papilla bleeding index (PBI), the periodontal pocket probing depth (PD) and the gingival recession. The fluid around the implant and the gingival sulcus fluid around the homologous tooth on the opposite lateral side were sampled. -----

Results:

The results have shown a positive API and PBI on 30% of the implants and a negative one on 70% of the implants. The average mucosal retraction measured around the implants was 0.15 mm, and the average probing depth was 2.25 mm. The API and PBI were positive on 78.3% of the homologous teeth. The average gingival retraction measured was 1.06 mm, and the average probing depth was 1.85 mm. Anaerobic bacteria were found in 12 out of 30 subjects (40%). Anaerobic bacteria were isolated only on the implant in 7 subjects, only on the homologous tooth in 3 subjects and both on the implant and the homologous tooth in 2 subjects. -----

Conclusions:

Anaerobic bacteria were more abundantly present on implants than on homologous teeth.

Abstract (croatian)

Svrha: Svrha studije bila je utvrditi ima li razlike u prisutnosti potencijalno patogenih anaerobnih mikroorganizama
oko implantata i homolognog zuba kod pacijenata koji su nakon postavljanja dentalnih
implantata bili upućeni u individualni pristup u održavanju oralne higijene. ----- Materijal i postupci:
U istraživanju je sudjelovalo 30 ispitanika (10 muškaraca i 20 žena) prosječne dobi 49,6 godina (22
– 78 godina). Implantati su bili protetički opskrbljeni metalkeramičkim krunicama prosječne starosti
5,26 godina (2 – 14 godina). Na kontrolnom pregledu parodontnom sondom zabilježeni su sljedeći
indeksi i mjere: aproksimalni indeks plaka (API), indeks krvareće papile (PBI), dubina sondiranja parodontnih
džepova (PD) i recesija gingive. Vestibularno se uzorkovala tekućina oko implantata i gingivalna
sulkusna tekućina oko homolognog zuba na kontralateralnoj strani. ----- Rezultati: Rezultati naše
studije pokazali su pozitivan API na 30 % implantata, a na 70 % bio je negativan. Vrijednosti PBI-ja
bile su identične vrijednostima API-ja. Izmjerena je prosječna retrakcija mukoze oko implantata od
0,15 mm i prosječna vrijednost dubine sondiranja oko implantata od 2,25 mm. Na homolognim zubima
API je bio pozitivan na 78,3 % zuba, kao i PBI. Izmjerena je prosječna retrakcija gingive od 1,06
mm i prosječna vrijednost dubine sondiranja od 1,85 mm. U skupini od 30 ispitanika, anaerobne bakterije
pronađene su kod njih 12 (40 %). Kod sedam ispitanika anaerobne bakterije izolirane su samo
na implantatu, kod tri samo na homolognom zubu, a kod dva i na implantatu i na homolognom zubu. -----
Zaključak: Zapaženo je više anaerobnih bakterija na implantatu u odnosu prema homolognom zubu.
