Brief summary

The aim of the present cross-sectional study is to assess the presence of AP and caries in psoriasis vulgaris individuals and to examine whether these medications influence these oral conditions. Therefore, 154 patients diagnosed with psoriasis were included in the study and subjected to oral examination to assess for presence of periapical lesions and caries experience.

Detailed description

The aim of the study is to evaluate the prevalence of apical periodontitis (AP) and caries in subjects with psoriasis vulgaris. 152 patients with psoriasis vulgaris were included in the study. The severity and extent of psoriasis were assessed according to The Psoriasis Area Severity Index (PASI), the Body Surface Area (BSA), and the Physician's Global Assessment Scale (PGA). Periapical status was assessed through dental examination and periapical radiographs. Data regarding Periapical Index (PAI), caries experience expressed as the Decayed, Missing, Filled Teeth Index (DMFT), and psoriasis medications were recorded. A predictive logistic regression model for the presence of AP and a linear regression model were then built to relate the severity and extent of AP to the type of drug therapy taken for psoriasis and to the severity and extent of the skin disease.

Design outcomes

Primary

MeasureTime frameDescription
Apical PeriodontitisThe time frame for this observational study is defined by the initial assessment conducted at baseline. No follow-up measurements are scheduled, and the study aims to explore associations and characteristics at a single time pointThe periapical status was investigated by palpation, percussion, thermal cold testing, and panoramic radiographs. Afterward, teeth that exhibited deep carious lesions, deep restorations, no response to pulp testing, or painful response to biting and/or percussion or palpation were suspected of AP. Those teeth underwent further periapical radiograph using the long cone paralleling technique with a film holder. AP cases were diagnosed based on the identification of at least one tooth with periapical radiolucency outpacing twice the width of the periodontal ligament space and having PAI \> 2.
Periapical Index Score (PAI)The time frame for this observational study is defined by the initial assessment conducted at baseline. No follow-up measurements are scheduled, and the study aims to explore associations and characteristics at a single time pointPeriapical health was assessed radiographically using the PAI score that was determined through visual inspection of the periapical area, assigning a numerical value based on the extent and severity of inflammation. Scores ranged from 0 to 5
The DMFT index is calculated by summing the scores for decayed (D), missing (M), and filled (F) teeth for an individual or a group of individualsThe time frame for this observational study is defined by the initial assessment conducted at baseline.
