Role of professional expertise in the decision-making process for periodontally compromised teeth.

The objective of this study was to evaluate factors that may influence decision-making with regard to extraction or maintenance of periodontally compromised teeth. A questionnaire with 2 distinct clinical scenarios, each including a radiographic image, was provided to students in their final year of dental school and practicing dentists. The participants were asked to record the action that they would take in each case (tooth maintenance vs extraction) and provide a justification for their decision. The questionnaires were answered by 158 dental students and 57 dentists (N = 215). Among the sample as a whole, 31.16% of participants recommended extraction in scenario 1, while only 5.58% recommended that action in scenario 2. In scenario 1, there was a statistically significant difference in the recommendations of the dental students and the dentists, with the former group significantly more disposed to conservative action, that is, maintenance of the tooth (P < 0.001; chi-square test). When the actions recommended by participants specializing in implants or periodontics (or both) were compared with those recommended by other specialists, there was a statistically significant difference between the groups regarding maintenance and extraction (P = 0.012; Fisher exact test), with the former group recommending fewer extractions. When the responses were evaluated in terms of the participants' years of specialty practice, it was observed that professionals with fewer than 20 years of practice were more conservative in their decisions, choosing tooth maintenance significantly more often than specialists with longer experience (P = 0.031; Fisher exact test). Among the majority of both dental students and practicing dentists, the decision in both scenarios was to maintain the compromised teeth; however, the results suggested that that both the years of experience of the individual and the specialty of the practitioner can influence decision-making.

Detection of human papillomavirus in dental biofilm and the uterine cervix of a pregnant adolescent.

CONTEXT: Adolescence and pregnancy are considered to be risk factors for human papillomavirus (HPV) infection. The relationship between this infection in the uterine cervix and oral HPV infection is controversial. CASE REPORT: This report describes a case of a pregnant 16-year-old adolescent who presented HPV infection in the uterine cervix and the mouth. Smears were collected from the cervix and the tongue/palate. Dental biofilm samples were also collected. The microarray technique was used to detect HPV. The HPV 56 subtype was observed in the cervical smear and HPV 6 in dental biofilm. CONCLUSION: In this pregnant adolescent, HPV infection was present in both the cervix and the mouth, but the HPV subtypes infecting these two areas were different.

CONTEXTO: A adolescência e a gestação são consideradas fatores de risco para a infecção pelo papilomavírus humano (HPV). A relação entre essa infecção no colo do útero e na boca num mesmo paciente é controversa. RELATO DE CASO: Descrever o caso de uma adolescente grávida de 16 anos que apresentou a infecção pelo HPV no colo do útero e na boca. Esfregaços foram realizados no colo do útero e em língua/palato. Amostras de biofilme dental também foram coletadas. Para detectar o HPV, foi utilizada a técnica do microarranjo. O HPV 56 foi o subtipo encontrado no esfregaço cervical e o tipo HPV 6 no biofilme dental. CONCLUSÕES: Observamos, nessa adolescente grávida, a presença do HPV na boca e no colo do útero, mas os subtipos virais que infectavam essas duas regiões eram distintos.
