BACKGROUND: The Mexican serviceberry, Malacomeles denticulata, have been used as a successful oral therapy by Mexican communities without enough scientific support. OBJECTIVE: To evaluate the M. denticulata extracts with selective antibacterial properties over dental biofilm bacteria. METHODS: Fruit, Leaf, and Stem of M. denticulata extracts were evaluated with micro-broth dilution method using ATCC bacteria. OD600 values had compared against each positive control (T-student-test). Anaerobically viability had confirmed by Colony-Forming-Units. Thin-Layer-Chromatography was used to identify the number of compounds and phytochemicals to identify secondary metabolites of the selected extracts. RESULTS: Streptococcus mutans showed Minimum-Bactericidal-Concentrations_(MBC) at 30 mg/mL to Fruit, Leaf, and Stem extracts. Periodontal-pathogens Aggregatibacter actinomycetemcomitans serotype b_(MBC = 30 mg/mL_p <  0.01); Fusobacterium nucleatum subsp. nucleatum_(MBC = 30 mg/mL_p<0.001); Parvimonas micra_(MBC = 15 mg/mL_NS); Porphyromonas gingivalis_(MBC = 30 mg/mL_NS); and Prevotella intermedia_(MBC = 3.75 mg/mL_NS) presented higher sensitivity to Leaf-Methanol, than the primary colonizers. Phytochemicals showed positive results to anthraquinones, coumarins, flavonoids, saponins, saponins steroids/triterpenoids, steroids/triterpenes, and tannins/phenols. CONCLUSION: We suggest the natural extracts of fruit and leaf of the Mexican serviceberry for the preventive use over the oral cariogenic or periodontal biofilm species, by their selective antibacterial properties against pathogenic species evaluated in-vitro, and due to the presence of antibacterial secondary metabolites identified as flavonoids and saponins of M. denticulata leaf extracts.

The aim of this research was to synthesize a hydrogel for wound dressing by mixing of polyvinyl alcohol (PVA) and chitosan (CTS) and processed by combination technique of freezing-thawing and irradiation by gamma ray, and to study of its properties. PVA aqueous solution 10% (w/v) was mixed with 2% (w/v) chitosan (CTS) solution and homogenized. The PVA-CTS mixture was processed by freezing-thawing up to 3 cycles, and then irradiated by gamma rays at the doseranged of 20-50 kGy  (dose rate was 10 kGy/hour). Result showed that PVA-CTS hydrogel with the gel fraction of 83%, 87%, 90%, and 83% were obtained at the irradiation dose of 20 kGy, 30 kGy, 40 kGy, and 50 kGy, respectively. Increasing of irradiation dose caused increasing of water absorption of hydrogel, i.e. 1.700 %, 1.715 %, 1.913 %, and 2.036 %, respectively, and the hydrogel reached the equilibrium in 25 hours. The hydrogel showed very slow water evaporation rate (~ 2%) at the initial time (1 hour) and then increased very fast (up ~50 %) at 24 h, i.e. 43%, 39.13%, 44%, and 53%, respectively. The elongation at break of hydrogels were obtained 245%, 322%, 322%, and 205% with the maximum value were obtained at irradiation dose ranged of 30-40 kGy. The presence of chitosan in the PVA hydrogel made it having higher antibacterial properties with the inhibitionzone value of 8 mm at irradiation dose of 30-40 kGy compared to PVA hydrogel as a negative control (6 mm) and to chloramphenicol as a positive control (8 mm).
