Abstract
Objective: This clinical study evaluated the success of two different splint materials bonded on periodontally treated mobile teeth.Methods: A total of 14 patients were included in the study. Patients were randomly assigned to the groups to receive either with or wire composite splint (WCS) or fiber-reinforced composite splint (FCS). Clinical periodontal parameters were performed and periotest values were recorded at baseline, and after 6 and 12 months. Patients were asked to complete a self-administered questionnaire after the splinting procedures. Failure types for the splints were categorized.Results: Baseline PI values showed significant decrease at 6 month follow up in the WCS (p=0.0019) and FCS (p<0.0001) groups and remained stable after 12 months (WCS; p=0.36, FCS; p=0.63). During the course of the study, PD and RD values exhibited no change between and within groups. Clinical parameters including PD, RD, PI and BOP were stable at 6 and 12 months follow-up period. In 6 patients (4 FCS, 2 WCS), reparable failures occurred during the observation period. In four patients (3 FCS, 1 WCS) splints failed completely and were removed. The periotest values of the failing teeth ranged between 47.3 and 50. In 3 patients in the WCS and 1 patient in the FCS group, periotest values were ? 40 but no splint failures were observed.Conclusion: FCS tends to show increased mechanical limitations compared to WCS. Teeth with periotest values above 40 may be more prone to splint failures independent of the splint material.
Highlights
Periodontitis is an inflammatory disease induced by bacterial biofilms that accumulate in the gingival margin and characterized by gingival inflammation, loss of connective tissue attachment and alveolar bone [1]
Power analysis was performed based on the Periotest values, and the results indicated that a number of 7 patients in each group is required to discriminate the difference between 2 groups (%80 power, alpha = 0.05) when anticipated Periotest value difference and standard deviation was 2.5 and 1.5, respectively
Inter - and intra-group assessments of periodontal parameters including Pocket depth (PD), Gingival recession (GR), clinical attachment level (CAL), Plaque index (PI) and Bleeding on probing (BOP) were similar between the fiber-reinforced composite splint (FCS) and wire composite splint (WCS) groups during the follow-up period (Figure 2)
Summary
Periodontitis is an inflammatory disease induced by bacterial biofilms that accumulate in the gingival margin and characterized by gingival inflammation, loss of connective tissue attachment and alveolar bone [1]. Calculus, elimination of deep periodontal pockets and occlusal adjustment are treatment options and result in healthy periodontium but reduced height of the supporting tissues [2]. The continuous loss of the supporting tissues during periodontal disease progression may result in increased tooth mobility, yielding to tooth drifting and exfoliation [3]. Tooth mobility can be a consequence of occlusal trauma in addition to the periodontal inflammation and attachment loss. From the clinical point of view, it is important to clarify the reason for increased tooth mobility as a result of widened periodontal ligament, reduced height of the supporting tissues or their combination[4]. Tooth mobility is a result of intra-alveolar displacement of the root and usually assessed by exposing the crown of the tooth to a certain force and determining the distance that the crown can be displaced in buccal and/or lingual direction [5]
