RESUMO
AIM AND OBJECTIVE: This study was done to assess peri-implant soft tissues and hard tissues in immediate and delayed titanium implants cases. MATERIALS AND METHODS: This study was conducted on 84 patients who were randomly divided into two groups. Group I was immediate implant group (42 patients) and group II was delayed implant group (42 patients). Parameters such as peri-implant esthetic score, crestal bone defect, and densitometry of peri-implant were evaluated after 1 week, 1 month, 3 months, and 6 months. RESULTS: The mean peri-implant esthetic score at first week in group I was 7.4 and in group II was 5.8, at first month in group I was 6.8 and in group II was 4.6, at third month in group I was 6.7 and in group II was 4.5 and at sixth month in group I was 6.4 and in group II was 4.4. The difference was significant (p value < 0.05). The mean peri-implant crestal bone loss (mm) after 1 week, 1 month, 3 months, and 6 months in group I was 0.24, 0.64, 0.86, and 1.04 and in group II was 0.28, 0.70, 0.94, and 1.14, respectively. The difference was nonsignificant (p value > 0.05). The mean peri-implant bone densitometry after 1 week, 1 month, 3 months, and 6 months in group I was 52.4, 45.6, 42.4, and 40.2 and in group II was 64.2, 60.5, 55.2, and 47.6, respectively. The difference was significant (p value < 0.05). CONCLUSION: Instantaneous implants exhibited enhanced esthetic and purposeful result such as healing of peri-implant bone and peri-implant soft tissues when compared to delayed implants. CLINICAL SIGNIFICANCE: Immediate implants can be used to improve esthetic and determined result in healing of peri-implant bone and peri-implant soft tissues.

AIM AND OBJECTIVE: To compare the effectiveness of erbium:yttrium-aluminum-garnet laser, GentleWave irradiation, photodynamic therapy (PDT), and sodium hypochlorite in smear layer removal and dentin permeability with a scanning electron microscope (SEM). MATERIALS AND METHODS: Seventy-five recently extracted single-rooted teeth (maxillary second premolars) were randomly divided into 5 groups of 15 each. Group I teeth was the control group in which conventional root canal preparation (RCP) [17% ethylenediaminetetraacetic acid (EDTA)] was done without laser irradiation, group II teeth underwent RCP and GentleWave™ treatment, group III teeth were subjected to Er:YAG laser irradiation, group IV uses low-level 660 nm (PDT), and group V samples were irrigated with 5.25% NaOCl. All samples were viewed under the SEM. Images at the coronal, middle, and apical part of the root canal were obtained at ×1000. A scoring system for smear layer removal and debris removal scoring was used for analysis. RESULTS: Smear layer removal was significantly higher at different points (coronal, middle, and apical area) in group I, followed by V, IV, II, and group III in declining order (p < 0.05). Intercomparison between the groups at different points indicates a significant difference in smear layer removal score between group I and group V at coronal, middle, and apical third. The result was not significant at coronal third and middle third, between group I and V, II and III, II and IV. The result was not significant at apical third between I and V, II and III, and II and IV (p < 0.05). Ethylenediaminetetraacetic acid and sodium hypochlorite are effective in smear layer removal followed by the Er-YAG laser technique. CONCLUSION: Ethylenediaminetetraacetic acid and NaOCl are effective in smear layer removal. Er:YAG laser-activated RCP was comparatively efficient in cleaning the smear layer and opening dentinal tubules. CLINICAL SIGNIFICANCE: Er:YAG laser-activated RCP was comparatively efficient in cleaning the smear layer and it can be used for effective removal of smear layer for clinical usage.
