Combination of orthodontic movement and periodontal therapy for full root coverage in a miller class iii recession: a case report with 12 years of follow-up

One of the main purposes of mucogingival therapy is to obtain full root coverage. Several treatment modalities have been developed, but few techniques can provide complete root coverage in a class III Miller recession. Thus, the aim of this case report is to present a successful clinical case of a Miller class III gingival recession in which complete root coverage was obtained by means of a multidisciplinary approach. A 17-year-old Caucasian female was referred for treatment of a gingival recession on the mandibular left central incisor. The following procedures were planned for root coverage in this case: free gingival graft, orthodontic movement by means of alignment and leveling and coronally advanced flap (CAF). The case has been followed up for 12 years and the patient presents no recession, no abnormal probing depth and no bleeding on probing, with a wide attached gingiva band. A compromised tooth with poor prognosis, which would be indicated for extraction, can be treated by orthodontic movement and periodontal therapy, with possibility of 100% root coverage in some class III recessions.

Um dos principais objetivos da terapia mucogengival é atingir a cobertura completa da raiz. Diversas modalidades de tratamento têm sido desenvolvidas, mas poucas técnicas podem obter a cobertura total da raiz em uma recessão gengival classe III de Miller. Assim, o objetivo deste relato é apresentar um caso de sucesso clínico de uma recessão gengival classe III de Miller na qual foi obtida a cobertura completa da raiz por meio de uma abordagem multidisciplinar. Uma jovem de 17 anos sexo feminino, leucoderma, foi encaminhada para tratamento de uma recessão gengival no incisivo central inferior esquerdo. Para a cobertura radicular foi planejado: enxerto gengival livre, movimento ortodôntico por meio de alinhamento e nivelamento e retalho reposicionado coronariamente (CAF). Este caso tem sido acompanhado por 12 anos e o paciente apresenta ausência de recessão, sem profundidade de sondagem anormal e sem sangramento à sondagem com ampla faixa de gengiva inserida. Dentes comprometidos e com mau prognóstico, que seriam extraídos em muitos casos, podem ser tratados por meio de movimento ortodôntico e terapia periodontal. 100% de cobertura da raiz é possível e pode ser conseguida em alguns casos de recessão gengival classe III.

Gingival overgrowth and drug association: A review.

Drugs used locally or systemically induce several alterations in micro and macroscopic tissues. However, nearly 20 drugs have been reported so far in the literature associated with gingival enlargement. Many systemic diseases have limited therapeutic options and such drugs or their metabolites have an adverse influence on different systems/organs, and one of these is that they initiate or accelerate the overgrowth of gingival tissue. The increase in size may be to the extent that teeth may be partially or completely covered, and the resultant 'gummy smile' may result in aesthetic concern for the patient.In the presence of bacterial inflammation in the gingiva, many of these drugs enhance the production of collagen by fibroblast cells, and simultaneously retard the destruction of collagen and hence increase the bulk of gingival tissue. It is apparent that there is a subpopulation of fibroblasts which is sensitive to these drugs. The exuberant growth of gingival tissue is of great aesthetic concern, which may require mechanical removal of bacterial plaque, calculus, and surgical intervention, and/or substitution of the drug with analogs. A relatively healthy oral environment provided by the dentist will reduce local microflora that will help in eliminating the major focus of infection. Physicians, general practitioners, and dentists need to make a coordinated and concise treatment plan that will be beneficial for the patients. This article will facilitate full information to physicians to involve dentists in the multidisciplinary treatment plan.
