Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The expected outcome was based on the null hypothesis where: the clinical longevity of the composite resin restorations performed after the 36 and 48 months period would be similar between the methods used for selective removal of caries lesions and the type of rehydration used in dentin .;We expect similarity in composite resin restorations after the 4-year follow-up period, regardless of the method of rehydration of the dentin used. | — |
Secondary
| Measure | Time frame |
|---|---|
| The clinical and photographic evaluation of the restorations was statistically analyzed by Kappa and Fisher's exact test (p <0.05). The results showed that there was no statistically significant difference between the groups tested for the retention criteria when a composite resin restoration performed after the selective removal of the caries using the Er: YAG laser biomodified with chlorhexidine had to be replaced. For the marginal discolouration criteria, there was a statistically significant difference for all the evaluated groups, where 5 composite resin restorations presented a Bravo score for the drill of the biomodified group with water, 5 for the biomodified drill group with chlorhexine, 13 for the Er: YAG group biomodified with water and 9 for the Er: YAG laser group biomodified with chlorhexine, after selective removal of caries lesions clinically followed for 4 years compared to the baseline. For the marginal adaptation criteria, there was a statistically significant difference for the Er: YAG group Biodegradable laser with chlorhexine, where 6 composite resin restorations presented Bravo score after selective removal of caries lesions after 4 years of clinical follow-up in relation to the baseline. For the secondary caries criteria there was no statistically significant difference between the evaluated groups, where a composite resin restoration performed after selective removal of biomodified caries lesions with water and two restorations of the biomodified laser group with chlorhexidine showed a recurrence of the caries and were repaired. ;The clinical evaluation of pulp vitality through the presence and / or absence of painful symptoms of percussion and / or spontaneous sensitivity, fistula and edema in the region of restored permanent molars will be analyzed statistically by the Kappa test and Fisher's exact test.;Radiographic evaluation of vitality pulp performed by the Strindberg index will be analyzed statistically by the Kappa test and Fisher's | — |
