Dental staff and patient attitudes about nicotine replacement therapy samples in dental care: A National Dental Practice-Based Research Network study.

OBJECTIVES: Cigarette smoking negatively affects oral health. Nicotine replacement therapies (NRT; e.g. nicotine patch or lozenge) and brief interventions (e.g. Ask-Advise-Refer; AAR) can improve cessation outcomes but are underutilized. NRT sampling (NRTS) increases NRT utilization by providing patients with samples of NRT as part of routine healthcare. Ask-Advise-Refer is a brief intervention where practitioners: ask patients about tobacco use, advise those using tobacco to quit and refer to the state quit line. The objective of this qualitative study was to explore dental care practitioners' and patients' attitudes and experiences regarding tobacco cessation treatment and perceptions of two brief intervention models, assessed separately: NRTS and AAR. METHODS: Twenty-four dental care practitioners and nine patients, recruited through the National Dental Practice-Based Research Network, participated in semi-structured telephone interviews. Interviews assessed experiences with tobacco use intervention and attitudes towards NRTS and AAR. Thematic analysis identified emergent themes related to feasibility and acceptability of NRTS and AAR. RESULTS: Practitioners varied on how they address tobacco use, from systematically to idiosyncratically. Some practitioners recommend NRT; few had prescribed it. Practitioners had favourable attitudes towards AAR and NRTS, with most believing that both interventions would be acceptable and feasible to implement. Concerns regarding AAR were time and patient resistance to discussing tobacco use. Concerns regarding NRTS were patient resistance to using NRT, side effects or medication interactions, and capacity to provide follow-up. Patients reported that oral health practitioners generally ask about tobacco use but do not provide interventions. Patients were open to discussing their tobacco use with practitioners and had favourable attitudes about NRTS. CONCLUSIONS: This formative work suggests that NRTS and AAR may be feasible to implement in dental care settings. Future studies are needed to assess the effectiveness and implementation potential of NRTS in dental care settings.

Symptom changes and crack progression in untreated cracked teeth: One-year findings from the National Dental Practice-Based Research Network.

OBJECTIVES: The study objective was to: (1) quantify symptom (pain) and crack changes during one year of follow-up, among teeth that had at least one visible crack at baseline but which did not receive treatment for those cracks; (2) identify any patient traits/behaviors and external tooth/crack characteristics correlated with these changes. METHODS: In this observational study, 209 National Dental Practice-Based Research Network dentists enrolled a convenience sample of 2858 subjects, each with a single, vital posterior tooth with at least one observed external crack; 1850 teeth remained untreated after one year of follow-up and were the cohort for analyses. Data were collected at the patient-, tooth-, and crack-level at baseline, one-year follow up (Y1), and interim visits. Associations between changes in symptoms and cracks were identified, as were changes in symptoms associated with baseline treatment recommendations. RESULTS: Changes in pain symptoms were observed in 32% of patients; decreases were twice as common as increases (23% vs. 10%). More changes were observed in cold pain than in biting pain and spontaneous pain combined; 2% had increases in biting pain and 2% in spontaneous pain. Only 6% had an increase in the number of cracks. Changes in pain symptoms were not associated with an increase in the number of cracks, but were associated with baseline treatment recommendations. Specifically, pain symptom changes (especially decreases) were more common when the tooth was recommended for treatment at baseline. CONCLUSIONS: Cracked teeth that have not received treatment one year after baseline do not show meaningful progression as measured by increased symptoms or number of cracks during follow-up. CLINICAL SIGNIFICANCE: Untreated cracked teeth, most of which were recommended for monitoring at baseline and some of which were recommended for treatment but did not receive treatment, remained relatively stable for one year with little progression of cracks or symptoms.
