  • Special Patient Care Effect of occlusal calculus utilized as a potential “biological sealant” in special needs patients with gastric feeding tubes: a qualitative in vitro contrast to pit and fissure sealant restorations

    Barry M. Owens

    2016 Jul/Aug; 64(4):24-29. 

    Marginal microleakage of intact occlusal calculus of primary molars extracted from a patient with a gastric feeding tube was compared with microleakage of pit and fissure sealants in calculus-free molars from a prior study. Observations indicated that calculus may serve as a “natural” occlusal surface sealant, rendering its removal from occlusal surfaces unnecessary in some patients.

    When a 9-year-old patient suffered external root resorption after avulsion and reimplantation of the permanent maxillary left lateral incisor, the root canal was obturated with gutta percha and mineral trioxide aggregate. The 3-year recall examination revealed no mobility, soft tissue alterations, or progression of resorption.

    This study assessed the impact of the width of keratinized mucosa (WKM) on periodontal parameters, including modified bleeding index, modified plaque index, modified gingival index, and gingival recession, and found that an association does exist between the WKM and peri-implant soft tissue health. A minimum of 2 mm of keratinized mucosa is recommended.

    A study evaluating the influence of material opacity and preheating on a composite resin demonstrated that preheating at 60°C reduced both the sorption and solubility of the composite, but the opacity only affected the results for a specific shade of the material.

    2016 Jul/Aug; 64(4):62-65.

    Antibiotic prophylaxis guidelines for the asplenic dental patient have changed over the last 30 years. While antibiotic prophylaxis is not routinely indicated prior to dental procedures for asplenic adult dental patients without risk factors, it should be considered for young children, immunocompromised patients with underlying disease, or any patient during the first 3 years after a splenectomy.

    To assess the effects of different surface treatments on adhesion of Candida albicans to porcelain, porcelain discs received no surface treatment or were glazed, overglazed, or polished. Adhesion of C albicans was lowest in the overglazed group, and polishing provided a surface as smooth as a glazed surface.

    2016 Jul/Aug; 64(4):e5-e9. 

    A study in medically compromised patients with gingival inflammation demonstrated that toothbrushing alone, with water but without toothpaste, improved the health of gingival tissues and reduced the biofilm. The addition of an antibiotic solution to the toothbrush increased healing and further reduced bacteria.
