These WHO key index age groups may be inserted into the global oral health databank and provide a 'pathfinder' baseline for formulating and conducting future public oral health programmes in the Republic of Moldova, with an emphasis on children in rural locations.
Objectives: The aim of this investigation was to evaluate the epidemiological data on dental injuries in permanent teeth among seventh and tenth grade schoolchildren in the Republic of Moldova. Study design:The pathfinder study model was chosen to evaluate the prevalence of Traumatic Dental Injuries (TDI). Schoolchildren ages 12 and 15 years old were examined: In the capital city (four schools), in two other major cities–(two schools each city), and in four villages (one per each village) in accordance with the WHO's recommendations. Results: A total of 720 seventh and tenth grade schoolchildren were examined. The overall prevalence of TDI was found to be 16.4% (total of 118 children). The prevalence of TDI was greater in the older age cohort (p<0.05). Children from rural areas presented with greater prevalence of TDI compared to children who live in urban region (p<0.03). The maxillary central incisors were found to be the most common teeth affected by trauma constituting 57.1% of the evaluated TDI cases. Enamel fracture was the main type of TDI (83%). Conclusions: The TDI mainly involved enamel fractures. Urban schoolchildren show lower rates of TDI compared to rural schoolchildren.
Background:
We aimed to compare the clinical and histological secondary healing effectiveness of various types of high-level laser versus scalpel excision in mucosa frenectomy.
Methods:
Forty-five Sprague Dawley rats were used in this study. These rats were divided into two laser intervention groups (CO2, n = 15; diode, n = 15) and one control group with scalpel excision (n = 15). The effectiveness of therapy has been assessed based on the comparison of intraoperative, postoperative, and histological parameters on days 7, 21, and 35, and postoperative weight changes as pain indicator.
Results:
Both laser groups demonstrated significantly (P < 0.05) less bleeding than did the control group during the intraoperative stage, whereas the CO2 laser showed more precise cutting compared with the diode laser (P < 0.05). The highest healing score was reported in the CO2 and scalpel groups on the first week of healing than in the diode group (P < 0.05). However, no significant difference was observed between the groups on days 21 and 35. Weight loss was significantly (P < 0.05) demonstrated in the diode group compared to the scalpel and CO2 groups till day 7. Both laser groups demonstrated delayed healing process compared with the scalpel. Nevertheless, the CO2 group followed the scalpel trends after day 7.
Conclusion:
Scalpel and CO2 laser yielded a superior clinical outcome compared with the diode excision of oral mucosa, whereby the CO2 has been proposed as the most effective laser type at the end of the first postoperative month.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
