Group 1
Teeth diagnosed with an indication for full coronal restoration and treated with stainless steel crown.
|
Clinical periodontal assessments were carried out for all participants at baseline (T0), as well as during the third-month (T1) and sixth-month (T2) follow-up visits. The clinical periodontal status was assessed with the probing pocket depth (PPD), bleeding on probing (BOP), plaque index (PI), and gingival index (GI). For each patient, GCF measurements and sample collection were performed at baseline (T0), as well as during the third-month (T1) and sixth-month (T2) visits. MMP-8 and IL-1β analyses were performed on GCF samples by the enzyme-linked immunosorbent assay (ELISA). |
|
Group 2
Teeth diagnosed with an indication for full coronal restoration and treated with prefabricated zirconia crown.
|
Clinical periodontal assessments were carried out for all participants at baseline (T0), as well as during the third-month (T1) and sixth-month (T2) follow-up visits. The clinical periodontal status was assessed with the probing pocket depth (PPD), bleeding on probing (BOP), plaque index (PI), and gingival index (GI). For each patient, GCF measurements and sample collection were performed at baseline (T0), as well as during the third-month (T1) and sixth-month (T2) visits. MMP-8 and IL-1β analyses were performed on GCF samples by the enzyme-linked immunosorbent assay (ELISA). |

Group 3
Teeth diagnosed with an indication for full coronal restoration and treated with fiber glass crown.
|
Clinical periodontal assessments were carried out for all participants at baseline (T0), as well as during the third-month (T1) and sixth-month (T2) follow-up visits. The clinical periodontal status was assessed with the probing pocket depth (PPD), bleeding on probing (BOP), plaque index (PI), and gingival index (GI). For each patient, GCF measurements and sample collection were performed at baseline (T0), as well as during the third-month (T1) and sixth-month (T2) visits. MMP-8 and IL-1β analyses were performed on GCF samples by the enzyme-linked immunosorbent assay (ELISA). |

Group 4
Healthy primary molars (control group)

assessment of probing pocket depth (PPD)
기간: From beginning to the end of treatment at 6 months
|
probing pocket depth (PPD) was measured the distance between the gingival margin and the deepest point of the sulcus.
PPD was evaluated from six surfaces (mesiobuccal, midbuccal, distobuccal, mesiolingual/mesiopalatal, midlingual/midpalatal, and distolingual/distopalatal) of the teeth.
The measurements were done utilizing a Williams periodontal probe.
|
From beginning to the end of treatment at 6 months
|
|
assessment of matrix metalloproteinase-8 (MMP-8) level in gingival crevicular fluid (GCF)
기간: in the sixth month (after sample collection was complete)
|
MMP-8 was performed on GCF samples by the enzyme-linked immunosorbent assay (ELISA) in the Medical Biochemistry Research and Application Laboratory of the Recep Tayyip Erdogan University Faculty of Medicine.
Twenty-four hours before the assay procedure, the eppendorf tubes were removed from the deep freezer and allowed to thaw progressively at -20 °C followed by +4 °C.
Prior to analysis, both the samples and assay reagents were equilibrated to room temperature (18-25 °C).
Each GCF specimen was analyzed individually without combining the samples.
The results were expressed in ng/mL (MMP-8).

|
Assessment of bleeding on probing (BOP)
기간: From beginning to the end of treatment at 6 months
|
Bleeding on probing (BOP) scores were obtained from four surfaces (mesial, distal, buccal, and palatal/lingual) of the primary second molars.
The measurements were done utilizing a Williams periodontal probe.
|
From beginning to the end of treatment at 6 months
|
|
Assessment of plaque index (PI)
기간: From beginning to the end of treatment at 6 months
|
Plaque index (PI) scores were obtained from four surfaces (mesial, distal, buccal, and palatal/lingual) of the primary second molars.
The measurements were done utilizing a Williams periodontal probe.
|
From beginning to the end of treatment at 6 months
|
|
Assessment of Gingival index (GI)
기간: From beginning to the end of treatment at 6 months
|
Gingival index (GI) scores were obtained from four surfaces (mesial, distal, buccal, and palatal/lingual) of the primary second molars.
The measurements were done utilizing a Williams periodontal probe.

|
Assessment of interleukin-1 beta (IL-1β) level in gingival crevicular fluid (GCF)
기간: in the sixth month (after sample collection was complete)
|
In GCF samples taken from patients, IL-1β level was determined by enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's instructions at the Medical Biochemistry Research and Application Laboratory of Recep Tayyip Erdoğan University Faculty of Medicine.
Twenty-four hours before the assay procedure, the eppendorf tubes were removed from the deep freezer and allowed to thaw progressively at -20 °C followed by +4 °C.
Prior to analysis, both the samples and assay reagents were equilibrated to room temperature (18-25 °C).
Each GCF specimen was analyzed individually without combining the samples.
The results were expressed in pg/mL (IL-1β).
