ABSTRACT
OBJECTIVES: The aim of this case series is to present the potential applications of the GingivalStat approach, that is, the use of temporary gingival stabilizers, to favor early gingival margin remodeling and prevent the occurrence of gingival rebound following esthetic clinical crown lengthening. CLINICAL CONSIDERATIONS: Four patients requiring clinical crown lengthening were treated for esthetical and functional reasons. The surgical approach included: (a) gingival margin recontouring; (b) full-thickness flap elevation; (c) osteotomy (to achieve an adequate dimension between the alveolar bone crest and the CEJ) and osteoplasty (to reduce the bone thickness and improve the buccal bone anatomic profile, where indicated); (d) temporary gingival stabilizer placement using a block-out resin or a composite (the GingivalStat approach); and (e) flap repositioning, adaptation, and suture. One- to five-year follow-ups, reported in the different case scenarios, show evidence of clinically stable gingival margins around the treated teeth. CONCLUSIONS: Within the limits of this case series, it can be concluded that the GingivalStat approach appears as a further maneuver to cope with clinical crown lengthening procedures at esthetic sites. GingivalStat seems to favor gingival margin contour remodeling during the early phase of healing as well as prevent the occurrence of gingival rebound. CLINICAL SIGNIFICANCE: GingivalStat approach may guide gingival margin remodeling and prevent gingival rebound after wound healing of sites submitted to esthetic clinical crown lengthening.

Este estudo propôs verificar a eficácia da utilização do laser de baixa intensidade (LBI) como terapêutica alternativa à terapia medicamentosa na redução da dor pós-operatória de cirurgias para aumento da coroa clínica. A amostra foi constituída por 30 pacientes adultos que foram divididos aleatoriamente em dois grupos: Grupo controle (n = 14) tratado com prescrição medicamentosa (Paracetamol 750 mg) e Grupo experimental (n = 16) tratados com laserterapia de baixa intensidade (seis aplicações pontuais, sendo três na região vestibular e três na palatina/lingual, de 20 mW/10 segundos, com comprimento de onda 660 nm, de 5 joules/ponto) imediatamente após o ato cirúrgico, em sete dias e 14 dias. Pode-se observar que o grupo experimental obteve melhores resultados, ou seja, menos dor que o grupo controle, porém sem diferença estatisticamente significante. Concluímos que o protocolo de aplicação LBI não apresentou resultados estatisticamente significantes, porém, a LBI foi uma terapia alternativa eficaz na redução da dor pós-operatória.
This study aimed to verify the effectiveness of the use of low intensity laser therapy (LILT) as an alternative therapy to drug therapy in reducing the postoperative pain of surgeries to increase clinical crown. The sample consisted of 30 adult patients and were randomly divided into two groups: control group (n=14) treated with conventional medication prescrition (Paracetamol 750mg) and experimental group (n=16) treated with low intesensity laser therapy (six specific applications, three in the buccal region and three in the palatal/lingual mW/10 20 seconds with a wavelength of 660 nm, 5 joules/ point) immediately after surgery, 7 and 14 days. In this study, we can observe that the experimental group achieved better results but the LILT was less pain referred to the control group, but no statistically significant difference. We conclude that the LILT application protocol did not result in statistically significant results. But based on the results obtained, we can conclude that LILT was an effective alternative therapy in reducing referred pain postoperatively.

AIM: The aim of this study was to evaluate the clinical outcome of teeth submitted to odontoplasty during clinical crown lengthening surgery (CCLS), when compared to their contralateral non-operated teeth. MATERIALS AND METHODS: Fourteen patients submitted to odontoplasty during CCLS were evaluated according to plaque index, bleeding on probing, probing depth and final restoration outcome (total success, relative success and failure). RESULTS: The mean follow-up period was 13.57 (± 8.00) months, and ranged from 6 to 24 months. Twelve cases presented total success of the final rehabilitation and 2 cases presented relative success. The cases of relative success were due to the necessity for a new periodontal intervention (scalling). No differences were observed with respect to periodontal parameters (P>0.05) and the patients that showed relative success presented generalized poor oral hygiene. CONCLUSIONS: The odontoplasty during clinical crown lengthening surgery is a feasible procedure in the management of extensive crown destruction.
