Results of a 20-year oral hygiene and prevention programme on caries and periodontal disease in children attended at a private periodontal practice.

OBJECTIVES: The objective of this study was to evaluate the long-term effect of an oral hygiene and prevention programme on caries and periodontal disease in a group of children attended at a private periodontal practice. METHODS: A total of 50 systemically healthy children, 25 males and 25 females, 03-13years old, were invited to join a long-term plaque control programme. All children had no caries and had no evidence of clinical bone loss. The participants were selected amongst children whose parents (mother, father or both) were treated of gingivitis, aggressive periodontitis or chronic periodontitis in a private periodontal practice. Subjects were separated in groups according to their parents' periodontal diagnosis, i.e., gingivitis, aggressive periodontitis or chronic periodontitis. The following outcomes were evaluated: a) probing depth, b) plaque (PI) and gingival (GI) indexes. The plaque control programme applied consisted of a regular maintenance regime at 6-to 12-month interval with an experienced periodontist. RESULTS: In total 30 subjects fulfilled the 20-year period of maintenance. The mean recall frequency was 6.4 (± 3.1) months, and the mean PI and GI were 0.4 (± 0.3) and 0.3 (± 0.3) respectively. The average rate of caries lesions was 1.0 (± 1.4). None of the patients exhibited clinical or radiographic evidences of alveolar bone loss, and no tooth was lost by caries. In addition, there were no statistically significant differences between groups (P>0.05). CONCLUSIONS: Adequate oral hygiene measures and periodic professional plaque control led to low levels of dental plaque, gingivitis and caries lesions.

Bony exostoses developed subsequent to free gingival grafts: case series.

Bony exostosis (BE) is described as a benign localised overgrowth of bone of unknown aetiology. Buccal bony exostosis (BBE) development secondary to soft tissue graft procedures has been reported in a small number of cases. The dental literature describes BBE development also at sites where free gingival grafts (FGG) have been used to increase the amount of gingiva. The following case series describes BBE development at nine sites (five cases) at which FGG was performed to increase the width of the attached gingiva. The presence of exostoses has been recognised during postoperative visits. Histological examination revealed osseous enlargements compatible with the diagnosis of exostoses at two re-entry procedures. In conclusion, based on previous reports, periosteal trauma, eg fenestration, seems to be the main aetiologic agent associated with the development of BBE in areas where FGG were placed.

Estudo clinico e histologico comparativo, em gengiva humana, da tecnica de sutura continua com duas agulhas em alca, com a tecnica de sutura interrompida interproximal. / Clinical and histological comparative study in human gingiva of the continuos suturing technic with two needles in loop with the interrupted interproximal suturing technic

Um estudo comparativo em gengiva humana foi realizado utilizando duas tecnicas de sutura: uma classica interrompida interproximal e outra continua com duas agulhas em alca. As diferencas clinicas observadas baseiam-se na melhor adaptacao obtida com o retalho e nas melhores condicoes de trabalho determinadas pela maior rapidez e maior facilidade na remocao do cimento cirurgico conseguidas com a tecnica de sutura continua. A analise da saude gengival no periodo de tres meses, alem de outros aspectos clinicos estudados nao puderam demonstrar diferencas apreciaveis existentes entre estas duas tecnicas. Os resultados histologicos demonstraram um mesmo padrao de reparacao, se bem que maturacao tecidual mais precoce e menor grau de inflamacao foram observados no lado em que utilizamos a tecnica continua com duas agulhas
