Congenitally missing teeth are a common developmental abnormality. It is defined as the developmental absence of teeth excluding the third molars. It is more commonly seen in permanent dentition but rarely in primary dentition. Second premolars are the most commonly missing teeth after the third molars. This paper reports a case of non-syndromic bilaterally congenitally missing second premolars in the mandibular region and its management.
Aim: Oral health can affect the quality of life (QoL), and the oral health impact profile-14 (OHIP-14) index utility to assess this impact. Objective: To study the impact of oral health on quality of life of patients older than 50 years, verifying, preliminarily, the reliability of the OHIP-14 index. Methods: We studied the internal consistency of the index by applying the alpha-Cronbach coefficient. The OHIP-14 index was obtained by the additive method, and the patients were divided according to gender, age and education level. Results: Considering all the issues that make up the OHIP-14 index, good internal consistency was obtained. The homogeneity of the questions in the index, it was confirmed that condition, since the difference between the value of the total Cronbach’s alpha-factor and issues was less than 0.03. The values of the intraclass correlation show the stability of their items. Conclusion: The OHIP-14 index was consistent and proved to be there relatively high impact of oral health on QoL of patients, with a predominance of physical pain in its components “feel bothered to feed” and “feel pain in the mouth” as well as the components of the psychological impairment.
Objectives: When using dental handpieces (HP), a phenomenon of backflow leads to an external and internal soiling and contamination of HP, especially in their narrow air/water pipes. To prevent any cross-infection, HP need to be sterilized after a thorough cleaning. This work aims to establish and assess a method for testing their cleaning. Indeed, there is a methodological gap concerning its validation because of their complex architecture.
Materials and Methods: This method is declined into a protocol using artificial soilings and ninhydrin tests. Its evaluation with a washer-disinfector-lubricator-dryer (WDLD) within 2 cleaning cycles with each 6 HP and after control tests, heads to validate its relevance and to demonstrate the effectiveness of the cleaning provided.
Results: After each cycle, all HP were externally clean. Our method also showed an internal cleanliness except for 2 HP whose engines in the automaton were defective.
Conclusion: This work fits with the improvement of infection control in dental practices. It is the first method developed to control the internal cleaning of HP without having to break them, and it demonstrates the need for HP to be put into an internal rotation during their cleaning. It fills the methodological gaps concerning their cleaning and allows assessing HP cleaning from dedicated WDLD. According to standard NF EN ISO15883, the method could be used for initial steps of operational or performances qualifications concerning HP cleaning.
