Gingival recession is a common manifestation in most populations. Gingival recession is clinically manifested by an apical displacement of the gingival tissues, leading to root surface exposure. Gingival recession may be a concern for patients for a number of reasons such as root hypersensitivity, erosion, root caries, and esthetics (Wennstrom 1996). Recently, new techniques have been suggested for the surgical treatment of multiple adjacent recession type defects. These are mainly derived from the coronally advanced flap, a supraperiosteal envelope technique in combination with a subepithelial connective tissue graft, or its evolution as a tunnel technique. The current case reports introduce a novel, minimally invasive approach applicable for both isolated recession defects as well as multiple contiguous defects in the maxillary anterior region. Access to the surgical site is obtained by means of an approach referred to as vestibular incision subperiosteal tunnel access.

Aims: The aim of this study was to estimate the pH of saliva, concentration of calcium and inorganic phosphate, and calculus formation before and after usage of Recaldent ® (GC Tooth Mousse Plus TM ), Functionalized Tricalcium Phosphate (3M ESPE ClinPro TM Tooth Creme) and standard dentifrice (Colgate dental cream). Settings and Design: Randomized double-blind study. Materials and Methods: A total of 50 subjects were recruited, the subjects were assessed at their first visit, on the 21 st day and on the 42 nd day. At the first visit, scaling was carried out and oral hygiene instructions were given. After 21 days, the subjects were given coded dentifrices where the operator and the subjects both were unaware of the type of dentifrice. Clinical parameters assessed were Plaque index, Gingival index, and Calculus index. Salivary samples were obtained to measure calcium, phosphate levels, and pH at 21 st day and 42 nd day. Statistical Analysis: ANOVA test, t-test, Mann-Whitney test, Kruskal-Wallis test. Results: The mean salivary calcium level and mean salivary phosphate level were higher in Group III (functionalized tricalcium phosphate (3M ESPE ClinPro TM Tooth Creme) as compared to Group II (Recaldent ® GC Tooth Mousse Plus TM ) and Group I (Colgate dental cream) on the 42 nd day after using dentifrices, which was statistically significant. This showed that the usage of remineralizing dentifrices led to an increase in the salivary calcium, phosphate, and pH but it did not reach the level of super saturation of the ions caused by elevated pH which could lead to calculus formation. Conclusions: Thought here was a statistically significant increase in salivary calcium and phosphate level in all three groups from baseline to 42 nd day, there was no calculus formation.
