Brief summary

To investigate the effects of using an intra-oral camera (IOC) during supportive periodontal therapy, and oral hygiene mobile text messages (SMS) between appointments on clinical, behavioral and psychological parameters of patients with gingivitis.

Detailed description

Dental hygiene behaviours are of paramount importance for controlling gingival health. There is evidence on the use of IOC and of text messages in boosting motivation, sustainability and clinical efficacy of dental hygiene behaviors. Orchestrating these two technologies is expected to create a coaction effect which could improve behavior change interventions, but the effectiveness of such strategy needs to be inspected.

Interventions

DEVICEMobile Text Messages

Dental inter-proximal control with floss holder and receiving 16 SMS during 4 months.

DEVICEIntra Oral Camera

SPT - Appointment with Intra-Oral Camera * Examination and diagnosis (15 min) using Intra-oral camera. * Motivation, discussion about desired outcomes and treatment needs (using Intra-oral camera) followed by instrumentation (scaling, polishing) (30 min).

Design outcomes

Primary

Measure	Time frame	Description
Change from BOMP (Bleeding on Marginal Probing) at 4 & 8 months	Baseline, 4 months & 8 months	Gingival bleeding Index

Secondary

Measure	Time frame	Description
HAPA (Health Action Process Approach) behavioral variables questionnaire.	Baseline, 4 & 8 months.	Measures adapted to oral health from previous studies with the HAPA model (Godinho et al. 2015) were used. All the HAPA variables were evaluated using a 7 point Likert-type scale, ranging from totally disagree (1) to totally agree (7), unless otherwise stated.
SMS (Short Messages Service) text messages opinion questionnaire	At 4 months.	Opinion about receiving SMS and how can it influence the appointment.
Intra Oral Camera opinion questionnaire	At 4 and 8 months.	Opinion about receiving Intra Oral camera and how can it influence the appointment.
Self-report Dental Hygiene Behaviors questionnaire.	Baseline, 4 and 8 months.	Level of toothbrushing and dental floss frequency.
