Clinical Performance of Orthodontic Bands in the Restorative Treatment of Hypomineralised Primary Second Molars
Clinical Performance of Orthodontic Bands in the Restorative Treatment of Hypomineralised Primary Second Molars: a Randomised Clinical Trial

Szczegółowy opis
Hypomineralised second primary molars are more susceptible to post-eruptive enamel breakdown, carious lesions, hypersensitivity, and premature tooth loss. Although preformed stainless steel crowns have demonstrated favourable clinical performance in primary molars, orthodontic bands may represent a less invasive restorative approach for maintaining affected teeth until physiological exfoliation. However, their clinical performance in hypomineralised primary teeth has not been investigated.
This parallel-group randomised clinical trial will include 30 children presenting at least one hypomineralised second primary molar with extensive post-eruptive enamel breakdown or a cavitated carious lesion requiring restorative treatment. Participants will be randomly allocated to receive either an orthodontic band cemented with glass ionomer luting cement after restoration of the cavitated lesion or a preformed stainless steel crown placed using the Hall technique. When more than one tooth is eligible, one index tooth will be randomly selected for the primary analysis.
Clinical assessments will be performed immediately after treatment and at 6, 12, and 18 months. Marginal adaptation, retention, and carious lesions adjacent to the restoration margins will be assessed using modified United States Public Health Service criteria. Biofilm accumulation will be assessed using the Silness and Löe Plaque Index. Treatment acceptability will be evaluated immediately after treatment using separate questionnaires for children and caregivers. Physiological exfoliation during follow-up will be recorded separately and will not be considered treatment failure.

Interwencja / Leczenie |
|---|---|
|
Eksperymentalny: Bands
Participants allocated to this arm will receive selective removal of softened carious dentine when carious tissue is present, followed by restoration of the cavity with conventional glass ionomer restorative cement (GC Gold Label 9).
A prefabricated stainless steel orthodontic band will then be adapted to the index tooth and cemented with glass ionomer luting cement (Meron).

Aktywny komparator: Crowns
articipants allocated to this arm will receive a preformed stainless steel crown placed using the Hall technique, without caries removal, local anaesthesia, or tooth preparation.
When a large cavity is present, glass ionomer restorative cement (GC Gold Label 9) will be placed at its base without prior caries removal.
The crown will be cemented with glass ionomer luting cement (Meron).

Podstawowe miary wyniku

Opis środka |
Ramy czasowe |
|---|---|---|
|
Marginal adaptation
Ramy czasowe: 18 months after treatment
|
Marginal adaptation will be assessed using modified United States Public Health Service criteria: Alpha, continuous margin without a detectable gap; Bravo, minor discontinuity not requiring clinical intervention; and Charlie, marginal defect requiring repair or replacement.
Alpha and Bravo will be considered clinically satisfactory, whereas Charlie will be considered a failure.
|
18 months after treatment
|
|
Retention
Ramy czasowe: 18 months after treatment
|
Retention will be classified as Alpha when the orthodontic band or stainless steel crown remains firmly cemented and functional, or Charlie when it is lost or dislodged and requires recementation or replacement.
Alpha will be considered successful retention and Charlie a failure.
|
18 months after treatment
|
|
Presence of carious lesions
Ramy czasowe: 18 months after treatment
|
Carious lesions adjacent to the restoration margins will be assessed clinically and classified as Alpha when absent or Charlie when present.
Alpha will be considered clinically satisfactory and Charlie a failure.

18 months after treatment

Biofilm accumulation
Ramy czasowe: Immediately after treatment and at 6, 12, and 18 months
|
Biofilm accumulation will be assessed using the Silness and Löe Plaque Index, ranging from 0 to 3: 0, absence of biofilm; 1, thin biofilm film along the free gingival margin; 2, moderate accumulation within the gingival sulcus; and 3, abundant accumulation within the gingival sulcus.
Lower scores indicate less biofilm accumulation.

Child-reported treatment acceptability
Ramy czasowe: Immediately after treatment
|
Acceptability will be assessed using a five-item questionnaire.
Each item will be scored from 0 to 4, resulting in a total score ranging from 0 to 20.
The negatively worded item will be reverse-scored.
Higher total scores indicate greater treatment acceptability.
